Abstract
The utility model discloses the bullet block structure that a kind of injection mold inside contracts in slide block, including mavable module core, wedge block, inside contract slide block, positive stop, jacking block, spring；The external wall of upper portion of described wedge block is inclined-plane, there is one section of straight figure on the top on this inclined-plane, inside contract slide block and slip in mavable module core, inside contract the inwall of slide block and the inclined-plane of wedge block external wall of upper portion against, positive stop activity is nested with in the vat inside contracting slide block step trough, the inner of jacking block is fixed in the middle part of positive stop, and the gap of outer end of jacking block is set in the sulculus inside contracting slide block step trough, and spring housing is connected on jacking block.Owing to the slide block that inside contracts of the present utility model moves inward, and jacking block is blocked by the wedge block above having straight figure thus realizes withstanding product and prevents from product to be bonded at inside contracting on slide block, when the straight figure of wedge block departs from positive stop, positive stop and jacking block just together with move inward, depart from the indent of plastic, complete action of loosing core, there is the reliable advantage of having stable behavior.
Description
Technical field
This utility model relates to a kind of injection mold, particularly relates to the bullet agllutination that a kind of injection mold inside contracts in slide block
Structure.
Background technology
Plastics injection mould is the instrument producing plastic, and application is widely.In plastic injection mo(u)lding, as
Shown in Fig. 1, owing to there is indent 101 inside of plastic 10, need to carry out side core-pulling, therefore, dealer is badly in need of designing one
The structure of side core-pulling.
Summary of the invention
The purpose of this utility model is to provide the reliable injection mold of a kind of having stable behavior to inside contract the bullet agllutination in slide block
Structure.
For achieving the above object, technical solution of the present utility model is:
This utility model is the bullet block structure that a kind of injection mold inside contracts in slide block, including mavable module core, wedge block, inside contracts cunning
Block, positive stop, jacking block, spring；Described wedge block activity is set in mavable module core, and the external wall of upper portion of wedge block is inclined-plane,
There is one section of straight figure on the top on this inclined-plane；The described slide block that inside contracts slips in mavable module core, and the inwall inside contracting slide block is oblique
Face, the inclined-plane of this inclined-plane and wedge block external wall of upper portion against, offer a step trough in the upper lateral inside contracting slide block；Described limit
Position block activity is nested with in the vat inside contracting slide block step trough, and the inner of jacking block is fixed in the middle part of positive stop, outside jacking block
Splaying is set in the sulculus inside contracting slide block step trough, and spring housing is connected on jacking block and the two ends of spring act against spacing respectively
Block and inside contracting on the cascaded surface of slide block step trough.
After using such scheme, owing to this utility model includes mavable module core, wedge block, inside contracts slide block, positive stop, top
Block, spring, when moving platen is released, inside contract slide block and move inward, and jacking block is blocked by the wedge block above having straight figure thus
Realization is withstood product and is prevented from product to be bonded at inside contracting on slide block, when the straight figure of wedge block departs from positive stop, positive stop and
Jacking block moves inward the most together, departs from the indent of plastic, completes action of loosing core, have the reliable advantage of having stable behavior.
With specific embodiment, this utility model is further described below in conjunction with the accompanying drawings.

Detailed description of the invention
As shown in Fig. 2, Fig. 3, Fig. 6, this utility model is the bullet block structure that a kind of injection mold inside contracts in slide block, including moving
Die 1, wedge block 2, inside contract slide block 3, positive stop 4, jacking block 5, spring 6.
Described wedge block 2 activity is set in mavable module core 1, and the external wall of upper portion of wedge block 2 is inclined-plane 21, on this inclined-plane 21
Top there is one section of straight figure 22.
The described slide block 3 that inside contracts slips in mavable module core 1, and the inwall inside contracting slide block 3 is inclined-plane 31, this inclined-plane 31 and wedging
The inclined-plane 21 of block 2 external wall of upper portion against, offer a step trough 32 in the upper lateral inside contracting slide block 3.
Described positive stop 4 activity is nested with in the vat inside contracting slide block 3 step trough 32, and the inner of jacking block 5 is fixed on
In the middle part of positive stop 4, the gap of outer end of jacking block 4 is set in the sulculus inside contracting slide block 3 step trough 32, and spring 6 is socketed in jacking block 4
Upper and spring 6 two ends act against positive stop 4 respectively and inside contract on the cascaded surface of slide block 3 step trough 32.
Operation principle of the present utility model:
As shown in Figure 4, Figure 5, when moving platen 20 is released, inside contract slide block 3 and move inward, and jacking block 5 is by above there being straight body
The wedge block 2 of section 22 blocks thus realizes withstanding product 10 and prevent from product 10 to be bonded at inside contracting on slide block 3, when the straight figure of wedge block 2
22 when departing from positive stop 4, positive stop 4 and jacking block 5 just together with move inward, depart from the indent 101 of product 10, complete
Loose core action, there is the reliable advantage of having stable behavior.During matched moulds, jacking block 5 playbacks under the effect of wedge block 2 and spring 6.
The above, only this utility model preferred embodiment, therefore can not limit what this utility model was implemented with this
Scope, the equivalence change i.e. made according to this utility model claim and description and modification, all should still belong to this reality
In the range of containing with new patent.
