Demolding structure of long-barrel-shaped injection molding part mold

Abstract

The invention discloses a demolding structure of a long-barrel-shaped injection molding part mold, relates to the technical field of mold periphery auxiliary devices, and solves the problems that whena cylindrical workpiece is taken out of a bottom mold cavity of an injection mold, hands are scalded by high temperature and injection molding burrs possibly exist by designing such auxiliary demolding and discharging device. The demolding structure of the long-barrel-shaped injection molding part mold comprises a part warping plate. A front rotating pipe and a rear rotating pipe are welded at the right side of the top face of a mounting frame in a perpendicular mode, and a rotating shaft runs through the two rotating pipes. The part warping plate is of a shallow groove cavity structure. Thewarping plate which is pressed downwards at the left side enables a brush-shaped washing shaft meshed with a gear in a cooling cabin at the left side to rotate in a linkage mode; and therefore, it canbe seen that the plastic burrs left on the surface of a workpiece sliding into the cooling cabin in the forming process is subjected to rotary sweeping, scraping and cleaning, and it can be seen thatthe device has the functional characteristics of auxiliary workpiece taking, cooling and synchronous burr cleaning.

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.
