Technical field
The present invention relates to a kind of injection molds, relate in particular to a kind of thermosetting property BMC plastic packaging stator plastic packaging mold.
Background technique
Tubular molding compound BMC is a kind of molding intermediate materials of semidry method manufacture glass-fiber reinforced thermo-setting product, by Unsaturated polyester resin, lower shrinkage/low-contour additive, initiator, inner pattern releasing agent applicable, mineral filler etc. are pre-mixed into paste, Thickener, colorant etc. are added, the glass fibre with different length is stirred in dedicated material kettle, thickened Journey ultimately forms the intermediary material of bulk, can be used for being molded and being molded.The material flowability is poor, in injection moulding process It is easily condensed in runner and die cavity, injection molding is caused to be unable to complete successfully even scrap of the product.
Summary of the invention
BMC material is made to flow smoothly thermosetting in runner the technical problems to be solved by the present invention are: providing one kind Property BMC plastic packaging stator plastic packaging mold.
In order to solve the above technical problems, the technical scheme adopted by the invention is as follows: the plastic mould of thermosetting property BMC plastic packaging stator Tool, including horizontally disposed bottom plate offer ejection hole in the middle part of bottom plate, and bottom plate two sides are equipped with parallels side by side, in parallels on bottom plate Between be movably equipped with and push away cladding plate, push away fixed vertical on cladding plate and be equipped with the lower thimble of several die sinking pushers, a pair of of parallels top is equipped with down Mounting plate, lower installation board are equipped with lower template, several lower mold cores are equipped in lower template, and lower template top is equipped with cope plate, upper mold Several upper cavities matched with each lower mold core are equipped in plate, two sides are equipped with spacer block side by side on cope plate, set between spacer block There are upper guidance tape and dirty guidance tape, the runner that the guidance tape that flows down is equipped with sprue and is connected with each upper cavity shunts Road is connected with the injection hole on upper cavity;Upper guidance tape top is equipped with upper mounting plate, and two sides are equipped with side by side on upper mounting plate Cushion block, two upper cushion block upper shelfs are equipped with top plate, and import department's circulation area of the runner is less than runner main part Circulation area is equipped with the shunting column of inverted cone-shaped, runner side flow path wall on upper guidance tape in the position for corresponding to injection hole The inner wall of elongated surfaces and injection hole is tangent;The flow path wall of the other side and the bottom cylindrical for shunting column are tangent.
As a preferred solution, it is equipped with cooling water channel in the upper guidance tape, is equipped with cooling in the dirty guidance tape Water channel.
As a preferred solution, several electric heating wires are equipped in the cope plate;It is equipped in the lower template several Electric heating wire.
As a preferred solution, be movably equipped with upper mold top roller in the top plate, upper mold top roller be located at below top plate Upper-mould top be connected, upper-mould top be equipped with several vertical die sinking pusher thimbles.
The beneficial effects of the present invention are: the flow passage structure of this mold make the material of flowing it is a large amount of it is close in injection hole The side wall of the tangent side of wall flows into injection hole, under the gap through injection hole and still is along still spiral.The structure So that Fluid pressure increases, fluid flowing is smooth, avoids material accumulation in runner and generates solidification phenomenon, so that injection-molded finished Rate greatly improves.
Due to being equipped with cooling water channel in upper guidance tape, cooling water channel is equipped in the guidance tape that flows down, it is ensured that material is flowing Shi Buhui condensation.
Due to being equipped with several electric heating wires in cope plate;It is equipped with several electric heating wires in lower template, is carried out after material injection Heating may make workpiece to be rapidly solidificated into type, improve injection efficiency.
Due to being movably equipped with upper mold top roller in top plate, upper mold top roller is connected with the upper-mould top being located at below top plate, on Mould top plate is equipped with several vertical die sinking pusher thimbles, facilitates the demoulding of workpiece, and can steadily deviate from workpiece, keeps away Stress is damaged when exempting from workpiece demoulding.
