Problems solved by technology

[0002] When the existing injection mold is demoulding the front mold and the rear mold, the front mold moves upwards under the drive of the driving part to complete the separation from the rear mold. At this time, since there are multiple limit points when the mold is closed, when the mold is demoulded, The limit points are separated, so that after demolding, the front mold will be offset in the plane, so that it will take extra time to calibrate the plane position when the next mold is closed, which will reduce the production efficiency, and the When , the structure is prone to excessive formation, wasting energy

Embodiment Construction

[0007] See figure 1 , which includes a front mold 1, a rear mold 2, A plate 3, and a B plate 4. There is a cavity between the front mold 1 and the rear mold 2 (not shown in the figure, which belongs to the existing mature structure), and the front mold 1 is fastened Connect A board 3, the relative positions of A board 3 and B board 4 are evenly distributed with guide grooves 5, the guide grooves 5 are arranged vertically, the limit bolts 6 are located in the guide grooves 5, and the guide grooves 5 run through B board 4, guide grooves 5 extends from bottom to top to the middle of plate A 3, the threaded part of the limit bolt 6 runs through the guide groove 5 from bottom to top and then fastens and connects to plate A 3, and the lower part of the limit bolt 6 is the bolt part 7.

Abstract

The invention provides a demolding limiting structure. Through the demolding limiting structure, in demolding, a front mold does not shift in the plane so that the next mold closing process can be carried out fast and accurately, and the distance of travel is less so that energy is saved. The demolding limiting structure comprises a front mold, a rear mold, an A plate and a B plate. A cavity is formed between the front mold and the rear mold. The front mold is fixedly connected to the A plate. The demolding limiting structure is characterized in that the opposite parts of the A plate and the B plate are provided with a guide groove; the guide groove is arranged vertically; a limiting bolt is arranged in the guide groove; the guide groove passes through the B plate and extends to the middle of the A plate from bottom to top; a screw thread part of the limiting bolt passes through the guide groove from bottom to top and is fixedly connected to the A plate; and the a lower part of the limiting bolt is a screw part.

Description

technical field [0001] The invention relates to the structural technical field of product molds, in particular to a mold release limiting structure. Background technique [0002] In the existing injection mold, when the front mold and the rear mold are demolded, the front mold moves upwards under the drive of the driving part to complete separation from the rear mold. At this time, since there are multiple limit points when the mold is closed, when the mold is demoulded, The limit points are separated, so that after the demoulding, the front mold will be offset in the plane, so that it will take extra time to calibrate the plane position when the next mold is closed, which will reduce the production efficiency, and the When , the structure is prone to excessive formation, wasting energy. Contents of the invention [0003] The invention provides a demoulding limiting structure, which prevents the front mold from shif...
