Description
Technical field
The utility model relates to a kind of mold ejection mechanisms, more particularly, to top opposite inside sliding block in a kind of injection mold
Mechanism out.
Background technique
A kind of equipment common in industrial production when injection mold can produce varied different plastic part and produce
Product, the scope of application is very extensive, the specific structure since Injection Molding Products shape difference itself is huge, in each mold
It is different from.In actual production, there are the moulding of many places bulge-structure, demolding structure in particular for some product sides
It is technical a great problem, the mode usually exited in product side setting sliding block, but often produce during demoulding
Product lateral projections position is bonded sliding block, and the structure of product side is directly damaged during sliding block exits, cannot be smoothly completed
Demoulding.
Utility model content
In view of the above-mentioned problems, the utility model is intended to provide in a kind of injection mold opposite ejecting mechanism inside sliding block,
By reducing the contact area of sliding block and product come so that sliding block will not damage product surface during exercise, by increasing auxiliary block
Mode carry out secondary separation, the process smoothly demoulded is effectively ensured, while protecting a product from damage.
The technical solution of the utility model is opposite ejecting mechanism inside sliding block in a kind of injection mold, including is located at product
The sliding block of two sides, is provided with the stepped mounting holes of multiple perforation sliding block sides in the sliding block, by extroversion in the mounting hole
It is inside sequentially installed with unhook, connecting rod and auxiliary block, end point is connected to sliding block lateral surface, the unhook inside on the outside of the unhook
Returning spring is provided between end and mounting hole, end point connects connecting rod on the inside of the unhook, and connecting rod is located in returning spring,
Returning spring is in compressive state when molding state, and the connecting rod other end is connected in auxiliary block, and the auxiliary block, which is located at, to be produced
On the outside of product in adjacent bulge-structure gap, bullet of the auxiliary block in returning spring when die sinking original state sliding block exits product two sides
It holds at the bulge-structure of product lateral surface on the lower still top of power effect.
Preferably, slanting guide pillar hole is provided on the outside of the sliding block, the inclined guide pillar of upper mold passes through slanting guide pillar hole, upper and lower mould die sinking
Shi Shangmo moves up through inclined guide pillar band movable slider and slides in and out far from product lateral surface.
The utility model structure novel, by existing slider designs at split type, guarantee will not damage during demoulding
Product surface, while the secondary phase in sliding block is designed to ejecting mechanism, smooth demoulding has been effectively ensured.

Specific embodiment
As shown in Figures 1 to 7, the utility model provides in a kind of injection mold opposite ejecting mechanism, packet inside sliding block
The sliding block 1 positioned at product two sides is included, the stepped mounting hole 2 of multiple perforation 1 sides of sliding block is provided in the sliding block 1, it is described
Ecto-entad is sequentially installed with unhook 3, connecting rod 4 and auxiliary block 5 in mounting hole 2, and 3 outside end points of the unhook are connected to sliding block
1 lateral surface is provided with returning spring 6, the connection of 3 inside end points of the unhook between unhook 3 inside ends and the mounting hole 2
Connecting rod 4, connecting rod 4 are located in returning spring 6, and returning spring 6 is in compressive state when molding state, and 4 other end of connecting rod connects
It connects in auxiliary block 5, the auxiliary block 5 is located in bulge-structure gap adjacent on the outside of product, and die sinking original state sliding block 1 moves back
Auxiliary block 5 under the elastic force effect of returning spring 6 still hold at the bulge-structure of product lateral surface by top when product two sides out.
Preferably, slanting guide pillar hole 7 is provided on the outside of the sliding block 1, the inclined guide pillar of upper mold passes through slanting guide pillar hole 7, upper and lower mould
Upper mold moves up through inclined guide pillar band movable slider 1 and slides in and out far from product lateral surface when die sinking.
The utility model is larger for that lateralarea, while surface is protruded but also with multiple tracks or concave inward structure portion
The product of position, this product itself difficulty in demoulding is very big, and existing sliding block stripping means are due to sliding block itself and product
Contact area is big, and when demoulding is easy to pull product surface, the smooth demoulding of this kind of product how is directed to, to industry technology people
It is always a technical problem for member.Auxiliary is arranged at product lateral surface protrusion or concave inward structure position in the utility model
Block will be that region that sliding block is contacted with product is changed to auxiliary block and contacts with product originally, so that practical top shoe is contacted with product
Region area be greatly reduced, the surface that sliding block is contacted with product is substantially flat surface, thus sliding block die sinking when to
Product surface will not be pulled when moving from product surface outside, while auxiliary block still is pushed up to hold and produced under the action of returning spring
Product surface, when the distance that sliding block moves out is greater than the stroke of returning spring, auxiliary block is followed by sliding block and moves out together,
Since contact area is small between each auxiliary block and product, product will not be damaged when auxiliary block is separated with product, herein
Demoulding is smoothly completed in the process.
The above is only the better embodiment of the utility model, not makees limit in any form to utility model
System, all technical principles according to the utility model any simple modification, equivalent variations or modification made to the above embodiment,
It is still within the scope of the technical solutions of the present invention.
