Catia Mold Tool Design Tutorial

Parting line

A parting linein industrial casting of moldsis the border line in which draft angles change direction. That is, it is the dividing line that splits the core and cavity halves of a molded part. It is sometimes a starting point for the mold parting surface. In engineering drawingparting line is often abbreviated as PL.

ASME 's Y Many molders will repair or even replace the mold tooling so that the flash is reduced to an acceptable tolerance or eliminated altogether.

Secondary operations to remove parting line flash include hand trimming, vibratory tumbling, media blasting and cryogenic deflashing. From Wikipedia, the free encyclopedia.

Injection moulding BrE or Injection molding AmEis a manufacturing process for producing parts by injecting material into a mould. Injection moulding can be performed with a host of materials mainly including metalsfor which the process is called die-castingglasseselastomersconfections, and most commonly thermoplastic and thermosetting polymers.

CATIA V5 Bottle Mold Design

Material for the part is fed into a heated barrel, mixed, and forced into a mould cavitywhere it cools and hardens to the configuration of the cavity. Injection moulding is widely used for manufacturing a variety of parts, from the smallest components to entire body panels of cars.

Advances in 3D printing technology, using photopolymers which do not melt during the injection moulding of some lower temperature thermoplastics, can be used for some simple injection moulds. Parts to be injection moulded must be very carefully designed to facilitate the moulding process; the material used for the part, the desired shape and features of the part, the material of the mould, and the properties of the moulding machine must all be taken into account.

The versatility of injection moulding is facilitated by this breadth of design considerations and possibilities. Injection moulding is used to create many things such as wire spools, packagingbottle capsautomotive parts and components, gameboyspocket combssome musical instruments and parts of themone-piece chairs and small tables, storage containers, mechanical parts including gearsand most other plastic products available today.

Injection moulding is the most common modern method of manufacturing plastic parts; it is ideal for producing high volumes of the same object. Injection moulding uses a ram or screw-type plunger to force molten plastic material into a mould cavity; this solidifies into a shape that has conformed to the contour of the mould.

It is most commonly used to process both thermoplastic and thermosetting polymerswith the volume used of the former being considerably higher. Thermoplastics also have an element of safety over thermosets; if a thermosetting polymer is not ejected from the injection barrel in a timely manner, chemical crosslinking may occur causing the screw and check valves to seize and potentially damaging the injection moulding machine. Injection moulding consists of high pressure injection of the raw material into a mould which shapes the polymer into the desired shape.

In multiple cavity moulds, each cavity can be identical and form the same parts or can be unique and form multiple different geometries during a single cycle. Moulds are generally made from tool steelsbut stainless steels and aluminium moulds are suitable for certain applications. Aluminium moulds typically are ill-suited for high volume production or parts with narrow dimensional tolerances, as they have inferior mechanical properties and are more prone to weardamage, and deformation during the injection and clamping cycles; however, aluminium moulds are cost-effective in low-volume applications, as mould fabrication costs and time are considerably reduced.

When thermoplastics are moulded, typically pelletised raw material is fed through a hopper into a heated barrel with a reciprocating screw. Upon entrance to the barrel the temperature increases and the Van der Waals forces that resist relative flow of individual chains are weakened as a result of increased space between molecules at higher thermal energy states.

This process reduces its viscositywhich enables the polymer to flow with the driving force of the injection unit. The screw delivers the raw material forward, mixes and homogenises the thermal and viscous distributions of the polymer, and reduces the required heating time by mechanically shearing the material and adding a significant amount of frictional heating to the polymer.

The material feeds forward through a check valve and collects at the front of the screw into a volume known as a shot.The following information defines the minimum requirements for Upmold injection molds produced by Upmold Engineering. Alternatives that will contribute to improved tool life, minimum wear, ease of molding, and ease of Manufacturing will be considered within the confines of the original quotation and Customer supplied mold design and build standards.

The Engineering Manager must approve any deviations from the Upmold standards, and any deviations must be documented and approved by the Customer.

Upmold molds are not recommended for abrasive or corrosive materials without written customer approval, and appropriate plating of all part related items. Nitriding is required otherwise, as in the case of straight wall lifter designs. Hardened S-7 steel should be considered for all lifter designs. The amount will be determined based on the mold size and number of ejector plate activated actions.

Standard inserted hardened interlocks are acceptable as the part design permits. All interlock designs must protect internal shut-offs. Examples given are the most common types as used by Upmold. The Customer will specify the general steel types.

China 38 Vietnam 1.The world of CAD offers many alternatives to shops that want to use the latest 3-D technology for their mold design. This article looks at the benefits of the various approaches and offers some tips on choosing the most appropriate one. The software will automatically create the necessary holes as components are added to the design. Many 3-D mold design systems include wizards to speed the design of the core and cavity from the product design.

Some 3-D software also incorporates a wizard to design the slides needed for parts incorporating undercuts. Creating the optimum split surface for the core often requires small adjustments, which can be undertaken most easily with surface modeling. Peter Dickin. The main methods for creating designs are solid modeling and surface modeling.

Surface modeling was the earliest form of CAD. It is based on shaping surfaces by pulling, bending, twisting and stretching them until the required shape is created. The surfaces can be joined together to enclose a volume and so represent complete objects. Solid modeling is based principally on standard geometric shapes, which can be combined in various ways, mainly developed from the Boolean operations of subtraction, addition and intersection.

When they were first introduced almost 20 years ago, solid modelers had the advantage of being much easier to learn and use, but they lacked the flexibility of surface modelers in creating complex shapes. Since then, the developers of surface modelers have made their systems much easier to use, while the suppliers of solid modelers have added more flexible modeling tools.

Thus, the distinction between the two types of system is now not so clear-cut. Surface modelers still have two general advantages over solid modelers for the first stage of the mold design, the creation of the core and cavity. First, they tend to be more tolerant of poor quality data.

Both types of programs offer methods for fixing problems—such as poorly trimmed surfaces or overlapping edges—that might result from inexperienced product designers or inaccurate data translation. However, surface modelers can usually import data that a solid modeler might fail to accept at all. Many surface and solid modeling programs offer wizards that can automate the creation of the core and cavity design from the part geometry.

In both cases, the wizards allow the process to be completed more quickly. However, surface modelers are more flexible when the split surface generated by the automated method needs small adjustments to give the optimal design. In general terms, solid modeling can be better for simpler product designs because it remains easier to use, while the greater flexibility of surface modeling will be better for producing tooling from more complex components.

The other key choice for the tooling designer is whether or not to import the design history with the product model. This history shows how the design was created and maintains relationships between different elements of the design.

Supporters of an integrated-software approach to product design and mold design claim that this is important as it allows changes to the product design to be reflected automatically in the mold design.

However, retaining the history can be a disadvantage when making minor changes to the product design to aid manufacturability. For example, the mold designer might want to increase the radius of one fillet in the model to improve material flow, but find that this is impossible without altering other linked fillets.

Similarly, he may wish to increase the draft angle on a single surface to make it easier to remove the part from the mold and discover that this cannot be done without affecting other surfaces.

Once the core and cavity have been finalized, work can begin on the remainder of the mold assembly. Since most mold components are made up from fairly simple, prismatic geometry, solid modeling is the most appropriate method for their design and their assembly into the overall mold. Catalogs of standard mold components are required to complete the mold design efficiently as the user does not want to spend time creating these components over and over again.

These catalogs are now available in a number of mold design systems, although the range of catalogs varies between the different systems. The software also needs to allow the moldmaker to design—quickly and easily—any non-standard components that might be required since few molds can be completed simply from standard components. As well as offering different catalogs, mold design systems differ in the degree of automation they incorporate.

Some software includes a special option that allows parametric components to react automatically as they are placed within an assembly, adding all of the necessary fit-features to the connecting components.Recommend Documents. Product overview. One experience.
