Abstract

The utility model discloses an ejection pile of an injection mold. The ejection pile comprises a cylindrical top (1) and a return spring (2) arranged on the outer side of the cylindrical top (1), wherein a square cavity (4) is arranged in the cylindrical top (1), a square column-shaped top (3) is embedded in the cavity (4), the side length of the square column-shaped top (3) is 0.5-0.8mm smaller than that of the cavity (4), and the bottom of the square column-shaped top (3) is clung to the bottom of the cavity (4). The square cavity is arranged in the cylindrical top, when the square column-shaped top is to be used, the square column-shaped top with specified height is inserted into the cavity, the formed ejection pile accords with the ejecting requirement of the product and then can be used; and the ejection pile of the injection mold is convenient to operate and is capable of increasing the working efficiency.

Description

A kind of injection mold ejects stake
Technical field
The utility model relates to the injection mold technical field, is specifically related to a kind of injection mold and ejects stake.
Background technology
Ejecting mechanism is to break away from public for the product with injection mo(u)lding, mother module core, in order to guarantee that product can break away from public affairs smoothly, mother module core, do not stay burr etc., for the different positions that ejects, need the difform stake that ejects, the stake that ejects commonly used is for the cylindrical, top that ejects the even product of injection moulding with for the square column type top that ejects the inhomogeneous product of injection moulding, when using ejecting mechanism, injection moulding shape for product, to eject effect in order improving, to need interim the replacing eject stake and since an ejecting mechanism to eject stake more, dismounting is wasted time and energy, and reduces production efficiency.
The utility model content
The purpose of this utility model is to overcome deficiency of the prior art, provides a kind of injection mold to eject stake, will square cavity be set in the cylindrical, top, when needs user cylindricality is pushed up, only need the square column type tip cutting of certain height is entered in the cavity, can use, easy to operate, enhance productivity.
In order to achieve the above object, the technical scheme that adopts of the utility model is:
A kind of injection mold ejects stake, comprise cylindrical, top and the return spring that is nested in the cylindrical, top outside, it is characterized in that: described cylindrical, top is provided with square cavity, described cavity is embedded with the square column type top, the little 0.5-0.8mm of the length of side of described square column type top side ratio cavity, the bottom of described square column type top/bottom part and cavity is close to.
Aforesaid a kind of injection mold ejects stake, it is characterized in that: the degree of depth of described cavity is 1/3rd of cylindrical, top height, and the height on described square column type top is the twice of cavity depth.
Aforesaid a kind of injection mold ejects stake, it is characterized in that: the length of side of described cavity equates with the cylindrical, top radius.
The beneficial effects of the utility model are: injection mold of the present utility model ejects stake, to square cavity be set in the cylindrical, top, when needs user cylindricality is pushed up, only need the square column type tip cutting of certain height is entered in the cavity, what form ejects the requirement that ejects that stake meets product, can use, easy to operate, enhance productivity.
Description of drawings
Fig. 1 is the structural representation that injection mold of the present utility model ejects stake.
Fig. 2 is that injection mold of the present utility model ejects the structural representation after the square column type top is inserted in stake.
The implication of mark is as follows in the accompanying drawing:
1: cylindrical, top; 2: return spring; 3: the square column type top; 4: cavity.
The specific embodiment
Below in conjunction with Figure of description, the utility model is further described.
As shown in Figure 1, a kind of injection mold ejects stake, comprise cylindrical, top 1 and the return spring 2 that is nested in dome 1 outside, cylindrical, top 1 is provided with square cavity 4, cavity 4 is interior can setting-in square column type top 3, square column type pushes up the little 0.5-0.8mm of the length of side of 3 side ratio cavitys 4, preferred 0.5mm fits more tight like this, prevents that square column type from pushing up 3 and rocking in cavity 4, and square column type pushes up the bottom of 3 bottoms and cavity 4 and is close to, the length of side of cavity 4 equates that with cylindrical, top 1 radius the degree of depth of cavity 4 is 1/3rd of cylindrical, top 1 height, according to the requirement for the treatment of demoulding product, here embodiment is that the height on square column type top 3 is the twice of cavity 4 degree of depth, meet the demoulding requirement that ejects the inhomogeneous product of injection moulding, the height on cylindricality top 3 does not limit, according to actual needs, easy to operate, enhance productivity.
More than show and described basic principle of the present utility model, principal character and advantage.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is by appending claims and equivalent circle thereof.

Claims (3)

1. an injection mold ejects stake, comprise cylindrical, top (1) and be nested in the return spring (2) in dome (1) outside, it is characterized in that: described cylindrical, top (1) is provided with square cavity (4), described cavity (4) is embedded with square column type top (3), the little 0.5-0.8mm of the length of side of described square column type top (3) side ratio cavity (4), bottom, described square column type top (3) is close to the bottom of cavity (4).
2. a kind of injection mold according to claim 1 ejects stake, it is characterized in that: the degree of depth of described cavity (4) is 1/3rd of cylindrical, top (1) height, and the height on described square column type top (3) is the twice of cavity (4) degree of depth.
