Abstract

The utility model discloses a belong to plastic injection mold technical field, especially a plastic injection mold's ejection mechanism. The utility model provides an easily take out the plastic injection mold's ejection mechanism of part, including end faller, a plurality of shaping ejector pin, end faller surface is provided with a plurality of first recesses, and every shaping ejector pin includes ejecting section, interlude, linkage segment, and the linkage segment of a shaping ejector pin matches to be installed in a first recess, and the diameter of the interlude of every shaping ejector pin is less than the diameter of ejecting section.

Description

A kind of ejecting mechanism of plastics injection mould
Technical field
The utility model relates to plastics injection mould technical field, especially a kind of ejecting mechanism of plastics injection mould.
Background technology
In plastic mold manufacture, the raised spiral of some plastic part products is on push rod, and comprise multiple convex tendon, so multiple shaping push rod must be used, shaping push rod is vertically installed in parallel in mold insert, and when producing, the section of ejecting of shaping push rod is mated with mold insert and is connected, after shaping push rod ejects, interlude is arranged in insert structure.Plastic part is formed after push rod ejects, and plastic material meets cold will contraction, to make between the convex tendon of plastic part, to shaping push rod generation clamping force that it is shaped, to cause difficult drop-off between shaping push rod and plastic part, the pickup difficulty of part.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of ejecting mechanism being easy to the plastics injection mould taking out part.
The utility model solves the ejecting mechanism of a kind of plastics injection mould that its technical problem adopts, comprise end needle plate, multiple shaping push rod, needle plate surface, the described end is provided with multiple first groove, each shaping push rod comprises the section of ejecting, interlude, linkage section, the linkage section Matching installation of a shaping push rod is in first groove, and the diameter of the interlude of each shaping push rod is less than the diameter of the section of ejecting.
Further, the interlude surface of each shaping push rod is provided with the second vertical groove.
Further, the linkage section place of each shaping push rod is provided with circular hole, and described circular hole is connected with rotating shaft, and described rotating shaft is arranged on end needle plate.
Further, described rotating shaft is straight pin.
Further, the bottom of each shaping push rod is provided with fillet structure.
The beneficial effects of the utility model are: the diameter diameter of the interlude of each shaping push rod being less than the section of ejecting, after shaping push rod ejects, what now shaping push rod was arranged in mold insert is interlude, so be that shaping push rod now and between mold insert exists gap, make shaping push rod be subject to plastics forming part convergent force to swinging to gap direction, reduce, to its clamping force, even to eliminate, be easy to the taking-up of plastics forming part, enhance productivity.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Parts, position and numbering in figure: end needle plate 1, first groove 11, shaping push rod 2, the section of ejecting 21, interlude 22, second groove 221, linkage section 23, circular hole 231, fillet structure 24, mold insert 3, face needle plate 4, plastics forming part 5, convex tendon 51.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, the ejecting mechanism of a kind of plastics injection mould of the utility model, comprise end needle plate 1, mold insert 3, face needle plate 4, multiple shaping push rod 2, end needle plate 1 surface is provided with multiple first groove 11, each shaping push rod 2 comprises the section of ejecting 21, interlude 22, linkage section 23, it is inner that all shaping push rods 2 are arranged on mold insert 3, the linkage section 23 of a shaping push rod 2 passes face needle plate 4 Matching installation in first groove 11, and there is gap between face needle plate 4 and shaping push rod 2, end needle plate 1, face needle plate 4 play fixing, spacing shaping push rod 4; The diameter of the interlude 22 of each shaping push rod 2 is less than the diameter of the section of ejecting 21.After shaping push rod 2 ejects, what now shaping push rod 2 was arranged in mold insert 3 is interlude 22, so be that shaping push rod 2 now and between mold insert 3 exists gap, shaping push rod 2 is made to be subject to plastics forming part 5 convergent force (mutually drawing close between convex tendon 51) to swinging to gap direction, reduce the clamping force to it, even eliminate, be easy to the taking-up of plastics forming part 5, enhance productivity.
Concrete, the diameter in order to the interlude 22 making shaping push rod 2 is less than the diameter of the section of ejecting 21, can be provided with the second vertical groove 221, second groove 221 diameter of interlude is diminished on interlude 22 surface of each shaping push rod 2.
Concrete, in order to be beneficial to the swing making shaping push rod 2 at taking-up part, linkage section 23 place of each shaping push rod 2 is provided with circular hole 231, and described circular hole 231 is connected with rotating shaft, and rotating shaft is arranged on end needle plate 1, and rotating shaft can select straight pin.In order to further, the bottom of each shaping push rod 2 can be provided with fillet structure 24.
