Abstract
The utility model provides a water pump stator injection mold, includes mould, lower mould and die cavity, is equipped with the opening on one side of upper mould lower part set up the locating piece in the opening, the locating piece pegs graft from top to bottom with the lower mould, the die cavity is arranged in respectively on mould, locating piece and the lower mould, is equipped with the jack that extends along upper and lower direction and correspond with the electricity plug of water pump stator on the locating piece. In the water pump stator injection molding process, the electric plug can be prevented from being broken while the electric plug is prevented from being injection-molded to form a protective layer, and the product molding rate is improved.
Description
Technical Field
The utility model relates to a water pump stator production facility especially relates to a water pump stator injection mold.
Background
The water pump stator is an important component of the water pump, and because the water pump is soaked in water during working, in order to prevent the water pump stator from short circuit, a protective layer needs to be injected outside the water pump stator. Traditional water pump stator injection mold comprises last mould, lower mould and die cavity, because of being equipped with the electric plug that connects that can not mould plastics on the water pump stator, above-mentioned water pump stator injection mold sets up the jack that corresponds with connecing the electric plug on last mould, will connect the electric plug to insert the jack, prevents to connect the electric plug by the protective layer of moulding plastics. Because connect the electric plug and incline or later stage collision leads to directional inaccurate when the assembly, at water pump stator injection mold compound die in-process, connect the electric plug and can't get into the jack smoothly and be gone into the mould striking rupture, cause the water pump stator to become the waste product.
Disclosure of Invention
The utility model relates to a solve above-mentioned technical problem, provide a water pump stator injection mold, at the water pump stator in-process of moulding plastics, it can avoid when the protective layer of moulding plastics will connect the electric plug, prevents to connect the electric plug rupture, improves the product shaping rate.
The technical solution of the utility model is that:
the utility model provides a water pump stator injection mold, includes mould, lower mould and die cavity, its special character lies in: the die cavity is respectively arranged on the upper die, the positioning block and the lower die, and the positioning block is provided with a jack which extends along the vertical direction and corresponds to an electric connection plug of the water pump stator.
Furthermore, a bolt is arranged on the lower surface of the positioning block, an insertion hole is formed in the upper surface of the lower die, and the bolt is vertically inserted into the insertion hole.
Furthermore, a first ejector rod penetrates through the lower die and is arranged at a position, corresponding to the positioning block, of the lower die, a second ejector rod penetrates through the lower die and is arranged at a position, corresponding to the cavity, of the lower die, the first ejector rod upwards ejects the positioning block, and the second ejector rod upwards ejects the water pump stator after injection molding.
Further, a push plate is fixedly installed at the lower end of the first ejector rod, the lower end of the second ejector rod is suspended above the push plate, the push plate moves upwards to push the first ejector rod and the second ejector rod successively, and then the positioning block and the water pump stator after injection molding are pushed upwards successively.
The utility model has the advantages that:
the injection molding machine is characterized in that a notch is formed in one side of the lower portion of the upper die, a positioning block is arranged in the notch, the positioning block is connected with the lower die in an inserting mode, a cavity is formed in the upper die, the positioning block and the lower die respectively, a jack which extends in the vertical direction and corresponds to an electric connection plug of a water pump stator is formed in the positioning block, the water pump stator is placed in the cavity of the lower die during injection molding operation, the positioning block is inserted into the upper surface of the lower die, the electric connection plug of the water pump stator is inserted into the jack of the positioning block, then the upper die is moved downwards to be matched, injection molding materials are filled in the cavity, and injection molding operation is completed. Because the electric plug is inserted into the jack of the positioning block in advance before die assembly, and the electric plug is righted in the plug assembling process of the positioning block and the lower die, the electric plug is prevented from being broken while the injection molding protective layer is avoided, and the product forming rate is improved.
