Side core-pulling mechanism for dog-leg cam of compression mould

Abstract

The invention discloses a side core-pulling mechanism for a dog-leg cam of a compression mould. The side core-pulling mechanism is installed on a male mould and a female mould of the compression mould, wherein the male mould and the female mould are oppositely assembled to form a cavity used for plastic compression moulding; and movable side cores capable of inserting in / retreating from the cavity under the driving of a moving mechanism is further arranged in a static mould. The side core-pulling mechanism further comprises the dog-leg cam, a slide block and an elastic element which are arranged on the male mould, and a press rod which is fixedly connected to the slide block, wherein the slide block is arranged in a slide block cavity in the female mould in a manner of slide fit, the end head of one end pointing at the female mould, of the dog-leg cam, is externally-tilted and provided with a rectangular section, and an inclined hole in slide fit with the dog-leg cam is formed in the slide block; the drive end of each movable side core is fixedly connected with the slide block; and the axial direction of the press rod is parallel to the axial direction of each movable side core, a shaft shoulder is further arranged on the press rod, and the elastic element is pressed onto the female mould by the shaft shoulder. The side core-pulling mechanism has the technical effects of saving labour and increasing production efficiency.

Description

technical field [0001] The invention relates to the field of plastic compression molding moulds, in particular to a bending pin lateral core-pulling mechanism of a compression mold. Background technique [0002] In the production of plastic products, especially the use of plastic raw materials with poor molding fluidity, compression molding technology is often used. Compression molding is also called compression molding and compression molding. Its working principle is: add loose plastic raw materials into the high-temperature cavity and feeding chamber, and then close the mold at a certain speed, and the plastic melts and flows under the action of heat and pressure. , and quickly fill the entire cavity, solidify and shape at the same time, and then open the mold to take out the product to become the required plastic part with a certain shape. The mold used for compression molding is called a compression mold, which usually includes a concave mold and a convex mold, and the...

AI Technical Summary

Problems solved by technology

[0004] The moving mechanism of the existing active core is mostly set independently, and the manual core pulling mechanism is widely used, which consumes a lot of manpower and the production efficiency is low; in contrast, the action of opening or closing the compression mold has been widely used such as a press. Higher efficiency bodies of the class as a power source
