The automatic demoulding mould
Technical field
The utility model belongs to a kind of mould, particularly relates to a kind of automatic demoulding mould.
Background technology
Present mould all is made up of upper die and lower die, when vulcanizing the back demoulding early stage, operator with vulcanizate with the mode of scratching, draw each product that from mold well, comes off. the bad height of product (cracky) after long, the demoulding of this mode activity duration, when vulcanizing the demoulding afterwards, product owing to vulcanizate inside skeleton (ironware) is arranged, cause rubber product sulfuration after-contraction limited, be difficult for the demoulding.
Summary of the invention
Goal of the invention of the present utility model is: at the problem of above-mentioned existence, provide a kind of solution product sulfuration back demoulding difficulty, improve demoulding efficiency, reduce the bad automatic demoulding mould that the demoulding causes.
The technical solution adopted in the utility model is such:
A kind of automatic demoulding mould comprises upper die and lower die, it is characterized in that: some intermediate die layers are arranged between counterdie and patrix, and independent of one another between the mould layer, after all part matched moulds, inside is model cavity.
Connect by reference column between the described mould layer.
Described some intermediate die layers are one deck.
On the described intermediate die layer semi-finished product workpiece is installed.
The pedestal of described counterdie is provided with top board, and movable fuse is arranged on the top board.
In sum, owing to adopted technique scheme, the beneficial effects of the utility model are: go up modular invariance, part separated into two parts with the difficult demoulding of counterdie, separate by mould three parts, cause product stripping to be simple and easy to get, it is bad effectively to control out the product that is molded as.
Description of drawings
Fig. 1 is the utility model STRUCTURE DECOMPOSITION schematic diagram.
Mark among the figure: 1 is patrix, and 2 is the intermediate die layer, and 3 is counterdie, and 4 is the semi-finished product workpiece, and 5 is reference column, and 6 is top board, and 7 is movable fuse, and 8 is pedestal.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is done detailed explanation.
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
As shown in Figure 1, a kind of automatic demoulding mould comprises patrix 1 and counterdie 3, it is characterized in that: one deck intermediate die layer 2 is arranged between counterdie 3 and patrix 1, semi-finished product workpiece 4 is installed on the intermediate die layer 2, and the pedestal 8 of counterdie 3 is provided with top board 6, and movable fuse 7 is arranged on the top board 6.
During work, the product after sulfuration is when the upper, middle and lower mould separates, when the top board 6 that arranges on the pedestal 8 upwards promotes, movable fuse 7 can be intermediate die layer 2 jack-up, product has spilt outside the mould most, causes product stripping to be simple and easy to get, and it is bad effectively to control out the product that is molded as.
The above only is preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of within spirit of the present utility model and principle, doing, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
