Injection mold with insert positioning function

Abstract

The invention discloses an injection mold with the insert positioning function. The injection mold comprises an insert mounting part; the insert mounting part is provided with threaded holes and is arranged on a mold body in a threaded connection mode; an insert mounting groove is formed in the insert mounting part; an insert positioning part is arranged at the side edge of the insert mounting groove; a storage cavity is formed in the insert positioning part; a limiting ball and a spring are arranged in the storage cavity; the spring abuts against the limiting ball to enable the limiting ballto be in a working state; an electromagnet and a heating body are arranged in the insert positioning part; the electromagnet is electrified and then attracts the limiting ball so as to enable the limiting ball to be separated from the working state; after the heating body heats a heat conductive part, the heat is transmitted to the limiting ball through the spring so that a metal insert can be heated when the limiting ball works; a vent hole is formed in the bottom of the insert mounting groove and is connected with an air inlet part; and the air inlet part is connected to an air pump. Compared with the prior art, the injection mold with the insert positioning function has the advantages that the metal insert can be limited at a preset position, and therefore accidents caused by disengagement of the metal insert can be avoided.

Description

technical field [0001] The invention belongs to the field of mold equipment for injection molding machines, in particular to an injection mold with insert positioning. Background technique [0002] Plastic products with inserts are widely used at present. It solves the problem that ordinary plastic parts cannot satisfy the mechanical properties, and improves the strength of plastic parts, especially in transmission. When designing molds for plastic products with inserts, it is important to consider how to ensure safe and reliable setting of inserts and efficient and stable production. [0003] Instructions attached figure 1 The part shown is a plastic product with an insert, which is used in a wide range of applications, mainly for transmissions. The plastic material for this part is ABS, with a metal shaft insert in an elongated shape resembling a worm. When designing the mold for this part, special consideration was required for the fixation of the metal insert and the ...

AI Technical Summary

Problems solved by technology

If the installation and fixing mechanism is not stable and reliable enough, the insert will be out of the original position when the film is laminated, which will cause the mold to be damaged

Moreover, it will also cause the ABS plastic melt to follow the axial runner to other positions of the mold, making the work impossible, and the operator must write down the mold to clean it up.

This not only affects the production and processing work, but also seriously reduces the quality of the product
