A mold release structure for long cylindrical injection molded parts

Abstract

The invention discloses a mold demoulding structure for a long cylindrical injection molded part, and relates to the technical field of auxiliary devices around the mold. By designing this auxiliary demoulding and discharging device, the problem of the removal of cylindrical workpieces from the bottom mold cavity of the injection mold is solved. , the high temperature is hot and there may be problems with injection molding hair. A mold release structure for a long cylindrical injection molded part, including a warp plate; the right side of the top surface of the mounting frame is welded with two rotating tubes at the front and rear in a vertical manner, and a rotating shaft runs through the two rotating tubes ; The rocker plate is a shallow groove structure, and the rocker plate that is pressed on the lower left will also make the brush-shaped washing shaft that is engaged with the gears in the cooling cabin on the left side rotate through linkage. The surface of the workpiece entering the cooling chamber is cleaned by rotating and scraping due to the plastic fluff left during molding. Therefore, it can be seen that the device has the functional characteristics of assisting in picking, cooling, and synchronously cleaning burrs.

Description

technical field [0001] The invention relates to the technical field of mold auxiliary tooling, in particular to a mold demoulding structure for a long cylindrical injection molded part. Background technique [0002] The mold used to make plastic products is an injection mold in a simple sense. When in use, the high-temperature solution obtained by melting the plastic is poured into the injection mold, and the plastic product is obtained through the cavity structure of the injection mold. This design The setting and description for the peripheral auxiliary devices of the upper and lower closing mode plastic injection molds used in the preparation process of cylindrical or round tube products. [0003] The structure of the combined mold injection mold described above, for example, discloses an injection mold in Chinese Patent No. CN201820174602.2, comprising: an upper mold and a lower mold; the upper mold is provided with a cylindrical upper mold core, and the upper mold core ...

AI Technical Summary

Problems solved by technology

[0005] The object of the present invention is to provide a mold demoulding structure for elongated cylindrical injection molded parts, so as to solve the problem that the existing mold is an injection mold with an upper mold and a lower mold. Due to the high heat left on it during pouring, when the mold is opened to pick up the piece, the residual heat and high temperature phenomenon will easily cause hand burns, and the taken out cylindrical product will leave edges in the middle and peripheral areas of the workpiece due to mold clamping. Edges or edges, and even burrs and burrs. This phenomenon is difficult to avoid, and subsequent manual polishing is required, which will affect the work efficiency of the final product.
