Abstract
The utility model discloses a mold insert mould for taking out core die lower surface through -hole, including hydro -cylinder, mold insert, the slider of loosing core, guide block and ejector pin, the output of hydro -cylinder with the one end of slider of loosing core is connected, loose core the slider with the guide block passes through the dovetail and connects, the guide block sets up the loose core top of slider, loose core the slider with all be provided with on the guide block with mold insert complex through -hole, the ejector pin passes loose core the slider with the guide block with the mold insert is connected. The utility model discloses a guide block, latch segment and mold insert three are fixed, so realize the axial motion of mold insert, accomplish the action of loosing core, and the structure is formed simply, and the product drawing of patterns is convenient.
Description
Technical field
The utility model relates to a kind of mould, refers more particularly to a kind of mold insert mould for core-pulling die lower surface through hole.
Background technology
In mold ejection structure, pneumatic jack application is more widely, the mould structure of existing conventional pneumatic jack, and demoulding difficulty is analyzed its main cause and is:
1, on product-forming, whole circle position of bone highest point is greater than 90mm, and the draft angle of two side is less, only has 0.2 degree, also has bottom surface to distribute many ribs simultaneously, and structure just determines the difficult demoulding of product.
2, product material uses TPO plastic rubber material, softer, sticking mould, die surface the rough and smooth all can increase knockout press, and die surface is too coarse, and when ejecting, frictional force is large, ejects difficulty; Die surface is smooth, and product laminating die surface, forms vacuum, ejects also difficulty, therefore the roughness of die surface needs strict control, but still has the problem ejecting difficulty.
3, dark cavity segment in the middle of ejecting structure, because there being the topology requirements such as oblique top, can not do first looses core ejects again, uses conventional thimble ejecting block, and because plastic material is softer, increasing ejects area, with large thimble and ejecting block as far as possible.But the position of bone is too dark, even if adopt large jacking block, still have top to protrude existing, muscle and the bad phenomenon of appearance occur.
Utility model content
It is simple that the purpose of this utility model is just to provide a kind of structure to solve the problem, the practical and convenient mold insert mould for core-pulling die lower surface through hole.
The utility model is achieved through the following technical solutions above-mentioned purpose:
The utility model comprises oil cylinder, mold insert, core-pulling slide block, guide pad and push rod, the output of described oil cylinder is connected with one end of described core-pulling slide block, described core-pulling slide block is connected by dovetail groove with described guide pad, described guide pad is arranged on the top of described core-pulling slide block, and described core-pulling slide block and described guide pad are provided with the through hole coordinated with described mold insert, and described push rod is connected with described mold insert with described guide pad through described core-pulling slide block.
Particularly, latch segment is provided with between described guide pad and described mold insert.
Further, the junction of described core-pulling slide block and chute is provided with dovetail chute.
The beneficial effects of the utility model are:
The utility model is fixed by guide pad, latch segment and mold insert three, so realize the axially-movable of mold insert, completes action of loosing core, and structure composition is simple, and product stripping is convenient.
Accompanying drawing explanation
Fig. 1 is three-dimensional structure diagram of the present utility model;
Fig. 2 is face upwarding stereogram of the present utility model;
In figure: 1-guide pad, 2-mold insert, 3-latch segment, 4-core-pulling slide block, 5-push rod, 6-oil cylinder, 7-chute.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As illustrated in fig. 1 and 2, the utility model comprises oil cylinder 6, mold insert 2, core-pulling slide block 4, guide pad 1 and push rod 5, the output of oil cylinder 6 is connected with one end of core-pulling slide block 4, and core-pulling slide block 4 is connected by dovetail groove with guide pad 1, and guide pad 1 is arranged on the top of core-pulling slide block 4, core-pulling slide block 4 and guide pad 1 are provided with the through hole coordinated with mold insert 2, and push rod is connected with mold insert with guide pad through core-pulling slide block.
Be provided with latch segment 3 between guide pad 1 and mold insert 2, core-pulling slide block 4 is provided with dovetail chute with the junction of chute 7.
Operation principle of the present utility model is as follows:
When oil cylinder 6 drives core-pulling slide block 4 horizontal movement, when moving to fixed position, push rod 5 moves, core-pulling slide block 4 does vertical motion through the guide pad 1 of dovetail configuration, because guide pad, latch segment and mold insert three fix, so realize the axially-movable of mold insert 2, complete action of loosing core.
These are only preferred embodiment of the present utility model, not in order to limit the utility model, all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included in protection domain of the present utility model.
