Abstract

The utility model discloses a kind of inexpensive secondary ejecting mechanisms for crystalline plastics, including thimble seat, material bar thimble, ejector retainner plate, template and at least two product thimbles;Product thimble bottom end is embedded on ejector retainner plate, and top is for ejecting product and is located in the through-hole opened up in template;Material bar thimble bottom is arranged return spring, and is fixedly connected with thimble seat, and top is used for ejecting product material bar, and is located at the positioning hole that template center position opens up;Material bar thimble bottom and the return spring being arranged thereon are all set in the accommodation groove that ejector retainner plate opens up;Expect the following table face contact of top and the product material bar of bar thimble and is not connected to.

Description

A kind of inexpensive secondary ejecting mechanism for crystalline plastics
Technical field
The utility model belongs to the technical field of injection molding production, and in particular to a kind of low cost two for crystalline plastics Secondary ejecting mechanism.
Background technique
When secondary ejecting mechanism is because of injection mould, compression mod, Double-ejection is needed in special knockout course, and at this time Secondary ejecting mechanism is needed to complete its function.Structure is complicated for the secondary ejecting mechanism of existing crystalline plastics, and on product top During out, cast gate is be easy to cause to pull, personnel have to carry out secondary operation to product again.
Utility model content
The purpose of this utility model is that be directed to above-mentioned deficiency in the prior art, provide a kind of for crystalline plastics Inexpensive secondary ejecting mechanism, to solve the problems, such as that the prior art be easy to cause product to pull and structure is complicated.
In order to achieve the above objectives, the technical scheme adopted by the utility model is that:
A kind of inexpensive secondary ejecting mechanism for crystalline plastics comprising thimble seat, material bar thimble, ejector retainner plate, Template and at least two product thimbles;Product thimble bottom end is embedded on ejector retainner plate, and top is for ejecting product and is located at mould In the through-hole opened up on plate;Material bar thimble bottom is arranged return spring, and is fixedly connected with thimble seat, and top is produced for ejecting Product material bar, and it is located at the positioning hole that template center position opens up;Material bar thimble bottom and the return spring being arranged thereon are equal It is set in the accommodation groove that ejector retainner plate opens up;Expect the following table face contact of top and the product material bar of bar thimble and is not connected to.
Preferably, accommodation groove is in convex, and open-topped aperture is less than the aperture of return spring.
Preferably, thimble seat is set in plastics board ejection position.
Preferably, two product thimbles are embedded on product thimble.
Inexpensive secondary ejecting mechanism provided by the utility model for crystalline plastics, has the advantages that
Upward active force (top power) of the utility model thimble seat by board, drives material bar thimble to move upwards, this When return spring compress, bear certain compressing force, and the deformation of return spring needs a process, therefore expect that bar thimble will first produce The ejection of product material bar, when return spring compression reaches ultimate attainment, ejector retainner plate drives product thimble to move upwards, and then by product top Out.The utility model separately ejects product material bar and product, can effectively improve product and pull problem, and the utility model The problem of structure is simple, can efficiently solve traditional mechanism structure is complicated.
Detailed description of the invention
Fig. 1 is the structure chart of the inexpensive secondary ejecting mechanism for crystalline plastics.
Fig. 2 is that the return spring of the inexpensive secondary ejecting mechanism for crystalline plastics compresses figure.
Fig. 3 falls figure for the inexpensive secondary ejecting mechanism product material bar for crystalline plastics.
Fig. 4 falls figure for the inexpensive secondary ejecting mechanism product for crystalline plastics.
Wherein, 1, thimble seat;2, ejector retainner plate;3, product thimble;4, template;5, product material bar;6, product;7, expect bar top Needle;8, return spring;9, location hole;10, through-hole;11, accommodation groove.
Specific embodiment
Specific embodiment of the present utility model is described below, in order to facilitate understanding by those skilled in the art The utility model, it should be apparent that the utility model is not limited to the range of specific embodiment, to the common skill of the art For art personnel, if various change the attached claims limit and determine the utility model spirit and scope in, These variations are it will be apparent that all are created using the utility model of the utility model design in the column of protection.
According to one embodiment of the application, with reference to Fig. 1, the inexpensive Double-ejection for crystalline plastics of this programme Mechanism, including thimble seat 1, material bar thimble 7, ejector retainner plate 2, template 4 and at least two product thimbles 3.
3 bottom end of product thimble is embedded on ejector retainner plate 2, and top is used for ejecting product 6, and opened up in template 4 In through-hole 10, through-hole 10 is consistent with the pore size of product thimble 3, it is ensured that uniform force during ejection of product 6.
Material 7 bottom of bar thimble is arranged return spring 8, and is fixedly connected with thimble seat 1, and top is used for ejecting product material bar 5, and be located in the location hole 9 that 4 center of template opens up.
Material 7 bottom of bar thimble and the return spring 8 being arranged thereon are all set in the accommodation groove 11 that ejector retainner plate 2 opens up, Expect the following table face contact of top and the product material bar 5 of bar thimble 7 and is not connected to.It is certain that return spring 8 is used to bearing thimble seat 1 Pressure, and in this process causes certain delay, i.e., after the ejection of product material bar 5, then product 6 is ejected, it is ensured that the two point Every ejection.
Accommodation groove 11 is in convex, and open-topped aperture is less than the aperture of return spring 8, for fixing return spring 8.Thimble seat 1 is set in plastics board ejection position, for bearing the upward active force of board.
Upward active force (top power) of the utility model thimble seat 1 by board, drives material bar thimble 7 to move upwards, Return spring 8 compresses at this time, bears certain compressing force, and the deformation of return spring 8 needs a process, therefore expects bar thimble 7 First product material bar 5 is ejected, when the compression of return spring 8 reaches ultimate attainment, ejector retainner plate 2 drives product thimble 3 to move upwards, in turn Product 6 is ejected.The utility model separately ejects product material bar 5 and product 6, can effectively improve product 6 and pull problem, And the utility model structure is simple, the problem of can efficiently solving traditional mechanism structure is complicated.
Although being described in detail in conjunction with specific embodiment of the attached drawing to utility model, should not be construed as to this The restriction of the protection scope of patent.In range described by claims, those skilled in the art are without creative work The various modifications and deformation that can make still belong to the protection scope of this patent.
