Abstract
The utility model relates to an injection mold of an electric smelting hot plate. The injection mold comprises a round plate, wherein the round plate is provided with a central hole and five branch runners, and the five branch runners are collected at the center of the central hole to form a main runner. According to the injection mold provided by the utility model, glue can be uniformly fed from five points of the central inner hole, so that the injection molding is directly realized; during injection molding, smelt plastic is simultaneously and quickly injected into a threaded slot inside the hot plate through the five points, so that the loss of injection pressure is reduced, and the hot plate can be successfully molded; in addition, by utilizing the injection mold provided by the utility model, after a product is molded, the shrinkage of the aperture of the central hole is smaller, so that the non-circularity of the inner hole of the hot plate reaches the size requirement; the electric smelting hot plate manufactured by the injection mold in the injection molding manner does not carry out secondary punching, so that the machining process is reduced, the pollution on the surfaces of products is reduced, and the production efficiency is improved.
Description
Technical field
The present invention relates to a kind of electric smelting heat dish injection mold.
Background technology
Because PE electric smelting saddle type main body is thinner with the wall thickness of heat dish, and there is multiple tracks fine thread groove inside, during injection moulding, enter glue has some setbacks very much, product is difficult to normal moulding, and its center bore out-of-roundness requires stricter, therefore at present general preparation method is that heat dish is made to solid plastic cement disk, then cut off the mouth of a river, after cooling Deng it, put into again on punch press and carry out punching by the mode of cold punching, although the method can guarantee hot disk center aperture out-of-roundness and reach dimensional requirement, but must turn the processing of order cold punching, make production efficiency lower, and product surface is easily subject to greasy dirt, the materials such as dust pollute, affect the welding quality of saddle type main product.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of electric smelting heat dish injection mold is provided.
Described electric smelting heat dish injection mold comprises disk, and disk is provided with centre bore and 5 runners, and described runner and disk junction are glue-feeder, and runner converges formation sprue in centre bore center.
Described disk inside is provided with fine thread groove.
In runner and disk junction, thimble is set.
Described glue-feeder is vertically towards thimble.
During injection moulding, molten plastic can enter glue by 5 glue-feeders simultaneously and enters fast heat dish internal whorl groove place, reduces the injection pressure loss, makes this heat dish moulding smoothly.
Compared with prior art, the mould that the utility model provides can adopt evenly enter glue and can reduce the injection pressure loss at 5, make this heat dish injection mo(u)lding smoothly, can make formed product rear center aperture shrink less simultaneously, guarantee that in heat dish, bore-out-of-round reaches dimensional requirement, use in addition the electric smelting heat dish of the utility model making without secondary punching, reduce manufacturing procedure, reduce product surface and pollute, enhance productivity.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model injection moulding schematic diagram;
Wherein 1 is disk, and centered by 2 hole, and 3 is sprue, and 4 is runner, and 5 is thimble.
The specific embodiment
A heat dish injection mold, comprises disk as shown in Figure 1, and disk is provided with centre bore and 5 runners, and described runner and disk junction are glue-feeder, and runner converges formation sprue in centre bore center.Described disk inside is provided with fine thread groove, in runner and disk junction, thimble is set, and described glue-feeder is vertically towards thimble.Manufacture the aperture requirement of Shi，An Re disk center and PE shrinkage factor and select the injection mold of an internal diameter specification, use higher injection speed and pressure to mold injection polyethylene melten gel, as shown in Figure 2; After the smooth moulding of product, die ejector pin is product automatic ejection, and the mouth of a river that then directly cuts off heat dish endoporus can obtain product.
