Die for producing four-way tube

Abstract

The invention provides a die for producing a four-way tube, and belongs to the technical field of dies. The die comprises: a movable die core provided with an arc-shaped groove and a forming part; a fixed seat which is fixedly provided with an arc-shaped guide rail; an arc-shaped rack which is movably connected with the arc-shaped guide rail; a connecting pull rod seat which is arranged in the arc-shaped groove and can move along the arc-shaped groove, wherein the connecting pull rod seat is fixedly connected with an arc-shaped rack; a first sliding block seat which is movably connected with the connecting pull rod seat, wherein the first sliding block seat can be close to or far away from the forming part; an arc-shaped mold core which is connected with the first sliding block seat; and a gear which is meshed with the arc-shaped rack, wherein the gear can drive the arc-shaped rack to move so as to drive the connecting pull rod base to move along the arc-shaped groove. The die has the beneficial effects that core pulling and demolding can be conducted on a Y-direction arc-shaped bent tube through rotation of the connecting pull rod seat and movement of the first sliding block seat.

Description

Technical field [0001] The present invention belongs to the field of mold, involving a mold for producing four-way tube. Background technique [0002] There is currently some plastic outer casings that produce production by injection molds, which have some complex structures to cause very difficulties in demolding. [0003] In order to overcome the problem of demolding, there are currently some easy-demold molds, such as Chinese patents, 201921162156.4, which disclose a mold structure of a rotating core release, for an internal threaded well product The upper mold assembly and the lower mold assembly, the upper die assembly, and the upper die assembly are included to form a cavity, which further includes a transverse core mechanism and a longitudinal core mechanism, and the longitudinal core mechanism is fixed to the upper fixation. Between the plate and the upper panel, the lateral core mechanism is provided between the upper panel and the lower template, and the lateral core me...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned mold is only suitable for demoulding of threaded holes, not suitable for demoulding of multi-pipe products. For example, when producing four-way pipes on some auto parts, there is a problem of difficult demoulding. The structure of this automobile plastic four-way pipe is very the complexity of

[0005] This four-way pipe has a main body, and four branch pipes are arranged on the main body, which are respectively a flange pipe, an oblique thin pipe, a Y-direction arc bend pipe and a right-angle bend pipe. The four branch pipes are interlaced, resulting in the existing It is difficult to pull the core out of the mold, especially the core pullout of the Y-direction curved pipe is more difficult. The existing core pullout structure cannot achieve the purpose of demoulding, so there is a certain room for improvement
