Description

Composite mold with 3D cooling channels

technical field

The utility model relates to an injection mold, and in particular to a composite mold with 3D cooling channels that can effectively improve cooling performance and is easy to be modularized to save manufacturing costs.

Background technique

In injection molding technology, in addition to considering the yield rate of parts, in order to shorten the molding time, holes are opened on the mold as cooling water channels, so that the mold can achieve a certain degree of uniform temperature through its own heat conduction, so as to achieve cooling. Colloid and achieve the purpose of molding, which is a well-known technology in the industry.

However, the cooling water channel on the traditional mold is limited by the processing method. Usually, the cooling water channel can only be formed on the mold by means of straight hole milling or drilling. Although the cooling water channel formed by the drilling method can control the temperature of the injection mold to a certain extent, the cooling water channel formed by the traditional drilling method cannot uniformly dissipate heat for the curved surface or complex shape of the product In the case of uneven heat dissipation of the mold, it will directly affect the quality of the injection parts, shrinkage yield, manufacturing time and cost. Therefore, how to achieve uniform heat dissipation design for the complex curved surface of the part has always been one of the topics of the industry's joint efforts. .

At present, the more popular mold cooling channel design scheme is to manufacture a special-shaped cooling channel (Conformal Cooling Channel) with 3D or complex curved surfaces by means of additive manufacturing technology (Additive Manufacturing, AM; also known as additive technology). Its technology is to use the method of layered processing and superposition forming to construct a 3D image file of the object to be produced, and then cut it into 2D planes layer by layer, and then stack the 2D planes layer by layer (such as Laser sintering layer by layer) to make a 3D entity by adding materials layer by layer. Using this layered manufacturing technology, a complex 3D cooling water channel can be directly formed on the mold. This, although it can solve the problem of heat dissipation in the traditional drilling water channel However, the cost of manufacturing entities with the current additive manufacturing technology is still high. If you want to make a mold with 3D cooling channels by stacking layers in a layer-by-layer manner, it is obviously not necessary in terms of manufacturing costs. Economical, and the greater the thickness of the object (mold) to be laminated, the higher the number of material stacks and the higher the manufacturing cost. Not exactly an ideal design option.

According to the experience, traditionally relying on drilling technology to manufacture cooling water channels has the problem of uneven heat dissipation. Although the existing build-up manufacturing technology can overcome the problem of temperature control, the greater the thickness of the material stack required for the mold, the greater the manufacturing cost. More expensive, less economical, and not suitable for modular mass production. Therefore, for the above two mold technologies for making cooling water channels, each has advantages and disadvantages and cannot be combined, that is, the following utility model is produced.
