Abstract
The utility model provides a molding die, belongs to the technical field of dies, and solves the problems that a casting runner in an existing die is long and thick, and more raw materials are stored in the casting runner, resulting in great waste, and furthermore, a pouring gate needs to be pruned, resulting in complicated production technology, high production cost and the like. The molding die comprises left and right die holders, wherein left and right die cores with a plurality of cavities are arranged inside the left and right die holders, respectively; the pouring gate corresponding to each cavity is formed on the right mold core; a heat preservation block and a mounting block are sequentially arranged on the right side of the right die holder; casting runners communicated with the pouring gate are arranged inside the right die holder and the heat preservation block; a heating device for heating and carrying out heat preservation on the casting runners is arranged inside the heat preservation block; a thimble which can extend to the pouring gate, blocks the pouring gate and is driven by a power device is fixed on the mounting block. The molding die has the advantages that no pouring gate is formed on the molded product, the utilization rate of raw materials is improved, the production cost is low, and the machining quality is ensured and enhanced.
Description
Technical field
The utility model belongs to technical field of mold, refers in particular to a kind of mould.
Background technology
The mould of existing plastics, rubber, is after raw material fusing, by runner, to inject in die, and cooling die makes goods cooling and shaping, then completes shearing, demoulding action.
In above-mentioned mould; on die, offer cast gate, sprue and runners is connected and realizes raw-material injection, so the goods after moulding also need to prune cast gate conventionally; and need reclaim reprocessing to raw material in mold runner; raw material in some mold runner can not be recycled, and because the casting runner in mould is all long thicker, the raw material of internal reservoir are more; cause great waste; also need in addition cast gate to prune, complex manufacturing, production cost is high.
Summary of the invention
The purpose of this utility model is to provide a kind of mould, and the part of its moulding is without pruning cast gate, and the material in the casting runner of mould directly utilizes in the time of can casting next time, does not waste raw material, is conducive to the production automation.
The purpose of this utility model is achieved in that
A kind of mould, comprise left and right die holder, it is characterized in that: in the die holder of left and right, be respectively arranged with the left and right die with a plurality of die cavities, on right die, offer the cast gate of corresponding each die cavity, the right side of right die holder is disposed with heat insulating block and mounting blocks, in right die holder and heat insulating block, be provided with the casting runner being communicated with cast gate, in heat insulating block, be provided with the heater to casting runner heating and thermal insulation, on mounting blocks, be fixed with the thimble being driven by power set that can extend cast gate and stop up cast gate, right die holder, on heat insulating block and mounting blocks, be provided with the through hole that thimble passes through, on heat insulating block, be provided with the charging aperture being communicated with the runner of casting.
In above-mentioned a kind of mould, described heater is electric heater unit, and described electric heater unit is electrically connected to the control box that is fixed on heat insulating block outside.
In above-mentioned a kind of mould, described power set are cylinder or hydraulic cylinder, and described cylinder or the action of hydraulic cylinder are controlled by the magnetic valve and the controller that are fixed in the control box in heat insulating block outside.
In above-mentioned a kind of mould, described a plurality of die cavities are two die cavities or four die cavities.
Than prior art, outstanding and useful technique effect is:
1, in the utility model, be provided with thimble, withstand cast gate after casting finishes, thereby make on moulded products, without cast gate, to have improved raw-material utilization rate, production cost is low.
2, casting runner of the present utility model adopts heater to add thermosetting hot flow path, keeps the temperature constant in runner, and melt temperature is well controlled, melt more uniformity enter each die cavity, the quality of processing parts is guaranteed and promotes.
3, the utility model is applicable to the cast molding mould with cushion block to high ferro casting.
Accompanying drawing explanation
Fig. 1 is structural upright schematic diagram of the present utility model.
Fig. 2 is partial structurtes schematic perspective view of the present utility model.
Fig. 3 is the half sectional view after STRUCTURE DECOMPOSITION of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, with specific embodiment, the utility model is further described, referring to Fig. 1-3:
A kind of mould, comprise left and right die holder (1, 4), in the die holder of left and right, be respectively arranged with the left and right die (2 with a plurality of die cavities 10, 3), on right die, offer the cast gate 11 of corresponding each die cavity, the right side of right die holder is disposed with heat insulating block 6 and mounting blocks 8, in right die holder and heat insulating block 6, be provided with the casting runner 13 being communicated with cast gate, in heat insulating block 6, be provided with the heater 7 to casting runner heating and thermal insulation, on mounting blocks 8, be fixed with the thimble being driven by power set 9 that can extend cast gate 11 and stop up cast gate 11, right die holder 4, on heat insulating block 6 and mounting blocks 8, be provided with the through hole (12 that thimble 9 passes through, 15, 16), on heat insulating block 6, be provided with the charging aperture 5 being communicated with the runner 12 of casting.
Operation principle of the present utility model is: adopted the plastics etc. of 7 pairs of fusings of heater to control temperature, after casting finishes, then when next time, casting started in runner plastics reheat fusing and can again start casting; Thimble extends cast gate 11 and stops up cast gate 11, can effectively guarantee that in die cavity, plastics do not flow backwards, and the goods that the demoulding simultaneously goes out are without cast gate, it is directly finished product, with respect to prior art, reduce follow-up manufacturing procedure, also reduced the waste for no reason of plastics, reduced production cost.
