The utility model provides a pair of multithread way injection mold carries out the transport of raw materials through a plurality of runner boards, realizes that the product of different dimensions can carry out the cooperation and the modification of runner, satisfies the production demand, reduces the mould cost simultaneously.
Description
Technical Field
The utility model relates to a multithread way injection mold.
Background
At present, injection molds are widely used, and in order to improve injection molding efficiency, mold cores in the molds are assembled by adopting insert structures, so that one set of molds can produce a plurality of products, an injection runner of the molds is particularly important, and because the runner bears the distance from a raw material to a cavity, the injection pressure and the flowing speed of the raw material in the runner need to be ensured during injection molding, the raw material can quickly enter the cavity and is not easy to cool due to the short runner, the product is easy to concentrate in stress and push, the raw material can be cooled too early due to the long runner, even the product is blocked in the runner, the production is influenced, the products produced by the molds of a plurality of inserts are different, the runner needs to be modified according to different products, and the high-efficiency original purpose of the multi-insert molds is violated.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a multithread way injection mold utilizes a plurality of templates to form the mould runner, realizes the different runners of different mold insert mould adaptations, and the combination of multilayer runner board can realize the velocity of flow control of raw materials in the mould simultaneously, improves production efficiency's simultaneous control cooling precision.
In order to solve the above problem, the utility model provides a pair of multi-runner injection mold has adopted following technical scheme:
a multi-runner injection mold comprises an upper mold, a runner assembly and a lower mold; the runner assembly is positioned between the upper die and the lower die and is connected with the upper die and the lower die; the runner assembly comprises a plurality of runner plates, and the runner plates are sequentially distributed between the upper die and the lower die; each runner plate is provided with an injection molding runner, and the injection molding runner is sunken on the runner plate.
Furthermore, each flow channel plate is provided with a positioning hole, and the positioning holes penetrate through the flow channel plate and are positioned on the periphery of the flow channel plate.
Furthermore, the number of the positioning holes is not less than two, and the positioning holes are symmetrically distributed on four corners of the runner plate.
Furthermore, each runner all be provided with the mouth of moulding plastics, the mouth of moulding plastics link up the runner board, communicate adjacent two the runner board.
Furthermore, the lower die is provided with a positioning pin, and the positioning pin extends upwards along the lower die and is matched with the runner plate.
The beneficial effects of the utility model reside in that: the utility model provides a pair of multithread way injection mold carries out the transport of raw materials through a plurality of runner boards, realizes that the product of different dimensions can carry out the cooperation and the modification of runner, satisfies the production demand, reduces the mould cost simultaneously.
