Abstract
The utility model discloses a two-slope secondary core-pulling structure of an injection mold. The structure comprises an upper mold, a lower mold, a first gliding block, a second gliding block, a locking block, a fixed column, an inclined guide column, an oil cylinder plate and an oil cylinder, wherein the first gliding block is glidingly connected onto the lower mold, the outer end of the first gliding block is connected with a rod end of a piston rod of the oil cylinder, and a cylinder body of the oil cylinder is fixed on the outer wall of the lower mold through the oil cylinder plate; upper parts of the fixed column and the inclined guide column are fixed on the upper mold, and lower parts of the fixed column and the inclined guide column are glidingly connected with guide column holes in the first gliding block and the second gliding block respectively; the second gliding block is glidingly connected onto the first gliding block, and the outer end of the second gliding block is propped against the locking block fixed on the outer wall of the upper mold. According to the structure, the two gliding blocks, namely, the first gliding block and the second gliding block, are adopted, the second gliding block is driven by the inclined guide column to finish core pulling of a side hole, and the first gliding block is driven by the oil cylinder to finish core pulling of a side pit, so that core pulling of the side hole and the side pit can be finished by the structure in one mold-opening process; and the structure is simpler in structure and reliable in action.
Description
Technical field
The utility model relates to a kind of mould of plastics, particularly relates to two kinds of gradient twice core pulling structures of a kind of injection mold.
Background technology
In mould for plastics, development is plastics injection mould faster.In the time of plastic shaping, not only require to improve the quality of products, enhance productivity, but also require mould structure simple, reduce and be produced into wood.But to plastic piece structure complexity and with side opening and the recessed product of profile side, some moulds go out the also more complicated of mould emptier of product at automatic trip, have a strong impact on service life and the maintenance of injection mold.At present, mostly adopt slide block to do side recessed, this structure need have left and right slide block, and production space, many caves is formed to restriction, and the profile of mould is larger, complex structure, and spue line affects product appearance.
Utility model content
The purpose of this utility model is to provide two kinds of gradient twice core pulling structures of injection mold of a kind of simple in structure, reliable in action.
For achieving the above object, technical solution of the present utility model is:
The utility model is two kinds of gradient twice core pulling structures of a kind of injection mold, and it comprises upper die and lower die, the first slide block, the second slide block, latch segment, fixed leg, Angle Pin, tank plate, oil cylinder; Described patrix and counterdie are oppositely arranged, and between forms die joint; The first described slide block slips on counterdie, and die cavity is stretched in the inner of the first slide block, and the outer end of the first slide block is connected with the rod end of the piston rod of oil cylinder, and the cylinder body of oil cylinder is fixed on by tank plate on the outer wall of counterdie; The top of described fixed leg is fixed on patrix, and slip in the guide pillar hole on its underpart and the first slide block; The second described slide block slips on the first slide block, and the inner of the second slide block is a core, and this core stretches into die cavity, and the outer end of the second slide block leans with the latch segment being fixed on patrix outer wall; The top of described Angle Pin is fixed on patrix, and slip in the guide pillar hole on its underpart and the second slide block.
Adopt after such scheme, because the utility model adopts two slide blocks such as the first slide block, the second slide block, drive the second slide block to complete loosing core of side opening by Angle Pin, complete recessed the loosing core of side by hydraulic oil cylinder driving the first slide block, make the utility model can in a die sinking process, complete side opening and recessed the loosing core of profile side, structure is comparatively simple, reliable in action.
Below in conjunction with the drawings and specific embodiments, the utility model is further described.
Accompanying drawing explanation
Fig. 1 is matched moulds state diagram of the present utility model;
Fig. 2 is parting state diagram of the present utility model.
The specific embodiment
As shown in Figure 1 and Figure 2, the utility model is two kinds of gradient twice core pulling structures of a kind of injection mold, and it comprises patrix 1, counterdie 2, the first slide block 3, the second slide block 4, latch segment 5, fixed leg 6, Angle Pin 7, tank plate 8, oil cylinder 9.
Described patrix 1 is oppositely arranged with counterdie 2, and between forms die joint.
The first described slide block 3 slips on counterdie 2, and the outer end that die cavity 10, the first slide blocks 3 are stretched in the inner of the first slide block 3 is connected with the rod end of the piston rod of oil cylinder 9, and the cylinder body of oil cylinder 9 is fixed on by tank plate 8 on the outer wall of counterdie 2; The top of described fixed leg 6 is fixed on patrix 1, and slip in the guide pillar hole on its underpart and the first slide block 3; The second described slide block 4 slips on the first slide block 3, and the inner of the second slide block 4 is a core 41, and the outer end that this core 41 stretches into die cavity 10, the second slide blocks 4 leans with the latch segment 5 being fixed on patrix 1 outer wall, and when matched moulds, latch segment 5 can lock the second slide block 4; The top of described Angle Pin 7 is fixed on patrix 1, and slip in the guide pillar hole on its underpart and the second slide block 4, drives the second slide block 4 to move around.
Operation principle of the present utility model:
When matched moulds, fixed leg 6 locks the first slide block 3, and latch segment 5 locks the second slide block 4.
When die sinking, Angle Pin 7 drives the second slide block 4 to complete loosing core of side opening; Oil cylinder 9 drives the first slide block 3 to complete recessed the loosing core of side, makes the utility model can in a die sinking process, complete side opening and recessed the loosing core of side.
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.
