What are the characteristics of the appearance design of injection moulds? Appearance design can leave a deep impression, consumers can’t see the internal quality of the product, but they can observe whether the product’s appearance design is smooth and the process quality is good, and then do a good job of overall accurate positioning of the product, such as appearance design is not standard, it may lead to the injection mold completely scrapped, so be

Calculation method of cavity and core working size of injection molding tool 1. Radial dimensions of the cavity and core (1) cavity radial size: injection mold cavity and core working size calculation,  the basic size of the plastic part is a large size, the tolerance is negative deviation. If the original tolerance on the plastic part of the label does not match this, should be converted to one-way negative deviation according to this provision. The

The design principle of injection mold launch mechanism (1) Push out mechanism should be set on the side of the moving mold as far as possible: Since the action of the push out mechanism is driven by the top bar installed on the injection molding mechanism, in general, the push out mechanism is located on the side of the moving mold. Because of this, the parting surface should be designed in such a way that

Structure composition and classification of injection mold push-out mechanism Before the injection parts are removed from the injection mold, there is a process of releasing the molded parts from the injection mold. The action of the push-out mechanism is done by the top bar or hydraulic cylinder mounted on the mold closing mechanism of the injection molding machine. (A) the composition of the launch mechanism In the injection mold, the push out mechanism is composed

When it comes to molds, people often associate die-casting molds with injection molds. In fact, the differences between the two are very large. By dry die casting, liquid or semi liquid metal is filled into the mold cavity at a very high speed and solidified under pressure to obtain a die casting. It is generally used for metal materials, and injection molding is the main method of thermoplastic molding. Thermoplastic plastic is made of thermoplastic
