Injection mold for producing sewage treatment pipe

Abstract

The invention provides an injection mold for producing a sewage treatment pipe. The injection mold comprises a central worm driving type gear de-threading mechanism, a threaded core rotating assemblyand a worm driving assembly; the central worm driving type gear de-threading mechanism aims at solving the technical problem that because the narrow space in a multi-cavity de-threading die gear de-threading mechanism cannot be fully utilized, the cost of single-mold manufacturing is increased, and has the beneficial effects that the that the problem that the internal thread demolding wrapping force of the product is difficult to fall off is solved. The injection mold has the beneficial effects that the demolding of threads is separated through the rotation of a threaded core, the demolding ofa product is performed by pushing an ejector rod and a push pipe on the outer circle of the thread, the thread is free of deformation, and the demolding action is reliable.

Description

technical field [0001] The invention relates to the technical field of moulds, in particular to an injection mold for producing sewage treatment pipes. Background technique [0002] In the manufacturing process of sewage treatment pipes, injection molds are often used for manufacturing and molding. In the thread-removing mechanism of injection molds, if the mold space structure is relatively narrow and the product requires a multi-cavity layout, rack drives are used to perform thread removal. One will increase the structural size of the mold, and the other requires more intermediate transfer mechanisms; the other is the need to add additional cylinder drive mechanisms, and the number of cavities in the multi-cavity layout will be reduced, and the space in the middle will not be fully utilized. The single mold manufacturing cost of the mold increases. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an injection m...
