Description
Technical field
The utility model relates to a kind of injection mold, particularly relates to a kind of slide block cavity inward turning and turns core-pulling mechanism.
Background technology
In mould for plastics, development is plastics injection mould faster.Its plastic product is also applied in daily life more and more widely, as each industrial circles such as building, machinery, electronics, instrument, instrument.The structure of the plastic product on existing market becomes increasingly complex, many plastic products all have inside groove, thereby require mould also have can this inside groove of injection moulding structure, this just requires to have a kind of structure that mould is extracted out from inside groove that can be intact, but this mould of can extracting out quickly and easily has certain difficulty, and this respect is also those skilled in the art's problem to be solved always, as, a kind of hearing aid earphone shell, it has a plurality of inside grooves, need employing repeatedly to loose core and just can complete the demoulding, structure is very complicated.
Utility model content
The purpose of this utility model is to provide a kind of slide block cavity inward turning with the demoulding of complicated inside groove moulding that completes to turn core-pulling mechanism.
For achieving the above object, technical solution of the present utility model is:
The utility model is that a kind of slide block cavity inward turning turns core-pulling mechanism, and it comprises take-up housing, the first slide block, the second slide block, the 3rd slide block, Four-slider, the 5th slide block, limited block, the top of the 5th described slide block has an accommodating cavity, and Four-slider activity is nested with in the accommodating cavity on the 5th slide block top, and the 5th slide block slips on the slide block guide rail of take-up housing by the two side on it, described limited block activity is equipped with on the sidewall on the 5th slide block top, and the two ends of limited block pass the sidewall on the 5th slide block top and lean with take-up housing inwall and the movable Four-slider sidewall being nested with at the 5th slide block accommodating cavity respectively, the lower end of the first described slide block is fixed on the upper end of Four-slider, the middle part of the second slide block is connected to the top of Four-slider in swingable mode by bearing pin, the bottom of the 3rd slide block is fixedly connected on the top of Four-slider, the first slide block is between the second slide block and the 3rd slide block, middle part at the first slide block is outwards convexly equipped with a projection, in the lower end of the second slide block, be provided with outside barb and this barb face relative with the bumping surface of the first slide block, the the first slide block projection top moving down is pressed the barb of the second slide block and is ordered about the second upper end of slide block and inwardly swings around its bearing pin.
Described limited block has two, respectively movable being located in the two side on the 5th slide block top; On two madial walls of take-up housing, be respectively equipped with the groove with limited block socket; On the two side of Four-slider, be respectively equipped with the groove with limited block socket.
Adopt after such scheme, because the activity of the utility model Four-slider is nested with in the accommodating cavity on the 5th slide block top and the 5th slide block slips in take-up housing by the two side on it, the 5th slide block can move relative to take-up housing, Four-slider can move relative to the 5th slide block, thereby form twice demoulding action, and being all fixed in upper end and second slide block of Four-slider, the 3rd slide block by bearing pin, in swingable mode, is connected to the top of the 5th slide block, the the first slide block projection moving down can push up to press the barb of the second slide block and order about the second upper end of slide block and inwardly swing around its bearing pin, realize the demoulding of the second slide block, the utility model is completed and there is the demoulding of complicated inside groove moulding.
Below in conjunction with the drawings and specific embodiments, the utility model is further described.
Accompanying drawing explanation
Fig. 1 is the state diagram of the utility model matched moulds;
Fig. 2 is that Four-slider of the present utility model starts retrude figure;
Fig. 3 is the state diagram that slide block of the present utility model departs from product completely.
The specific embodiment
As shown in Figure 1, the utility model is that a kind of slide block cavity inward turning turns core-pulling mechanism, and it comprises take-up housing 1, the first slide block 2, the second slide block 3, the 3rd slide block 4, Four-slider 5, the 5th slide block 6, limited block 7.
The top of the 5th described slide block 6 has 61, the Four-slider 5 activities of an accommodating cavity and is nested with in the accommodating cavity 61 on the 5th slide block 6 tops, and the 5th slide block 6 slips on the slide block guide rail of take-up housing 1 by the two side on it.
Described limited block 7 has two, activity is located in the two side on the 5th slide block 6 tops respectively, and the two ends of limited block 7 pass the sidewall on the 5th slide block 6 tops and lean with take-up housing 1 inwall and movable Four-slider 5 sidewalls that are nested with at the 5th slide block 6 accommodating cavities 61 respectively.On two madial walls of take-up housing 1, be respectively equipped with the groove 11 with limited block 7 sockets; On the two side of Four-slider 5, be respectively equipped with the groove 51 with limited block 7 sockets.
The lower end of the first described slide block 2 is fixed on the upper end of Four-slider 5, the middle part of the second slide block 3 is connected to the top of Four-slider 5 in swingable mode by bearing pin 8, the bottom of the 3rd slide block 4 is fixedly connected on the top of Four-slider 5, the first slide block 2 is between the second slide block 3 and the 3rd slide block 4, at the middle part of the first slide block 2, be outwards convexly equipped with a projection 21, in the lower end of the second slide block 3, be provided with outside barb 31 and 31 of this barbs relative with 21 of the projections of the first slide block 2, the first slide block 2 projections 21 that move down can push up to press the barb 31 of the second slide block 3 and order about the second slide block 3 upper ends and inwardly swing around its bearing pin 8, thereby the demoulding.
The course of work of the present utility model:
1, as shown in Figure 2, while moving after Four-slider 5, the first slide block 2 also moves together backward, the first slide block 2 projections 21 that move down can push up to press the barb 31 of the second slide block 3 and order about the second slide block 3 upper ends and swing around its bearing pin 8 inside (along Four-slider 5 vertical direction), throw off head forming area.
2, as shown in Figure 3, Four-slider 5 continues to move down until contact with the 5th slide block 6 and limited block 7 snaps in the groove 51 of Four-slider 5, promote the 5th slide block 6 and move together, the groove 11 that limited block 7 departs from take-up housing 1, thus whole slide block is spun off in product 10
The above, it is only the utility model preferred embodiment, therefore can not limit the scope that the utility model is implemented with this, the equivalence of doing according to the utility model claim and description changes and modifies, and all should still belong in the scope that the utility model patent contains.
