Description
Technical field
The invention belongs to mold production equipment technologies, and in particular to a kind of to be bonded the anti-top plain boiled water bucket injection mould of part
Tool.
Background technique
Injection mold is the mould and tool with required product pattern, and the plastic composition matter of melting is injected in mold,
Cooling, pressure maintaining, demoulding forms the product of required pattern, generally circulation production model, short molding cycle, high production efficiency,
Melt is small to the abrasion of mold, can forming shape is complicated in large quantity, picture on surface and label is clear, dimensional accuracy is high product
Plastic, but the prior art considers unfortunately:
In bucket mold injection molding production process, demoulds part and generally used thimble, the product plastic that will have been cooled down,
From the intracavitary ejection of lower die, due to cooling not enough thoroughly either because the plastics after melting have certain viscosity, adherency
On the surface of lower mold cavity, thimble is too small with plastic contact area when jacking up plastic, since thimble has climbing power,
Then the pressure excessive for plastic surface is formd, the surface of plastics is squeezed, its modification is stretched, changes surface thickness at this
It is different with the thickness in other places, white convex at stretching, or even plastic bucket surface fracture can be made to crack, lead to bucket
Occurs leak in use process later, or fragmentation easily.
Summary of the invention
In view of the deficienciess of the prior art, being bonded the anti-top plain boiled water bucket injection mould of part it is an object of the present invention to provide a kind of
Tool, to solve to be adhered in lower die due to cooling not enough thoroughly either because the plastics after melting have certain viscosity
The surface of chamber, thimble is too small with plastic contact area when jacking up plastic, since thimble has climbing power, is then formed
The pressure excessive for plastic surface, squeezes the surface of plastics, stretches its modification, changes at this surface thickness and other
The thickness of side is different, white convex at stretching, or even plastic bucket surface fracture can be made to crack, and causes bucket later
Occur leak in use process, or easily fragmentation the problem of.
To achieve the goals above, the present invention is to realize by the following technical solutions: a kind of to be bonded the anti-top of part white

Slot b roll inside, the track sliding being equipped with inside pattern main body 462, jacks up 4611 holding level of lid and moves up, will form
Plastic jack up, jack up lid 4611 and have rotary force, will not have with molding plastic it is glutinous and, and because of the contact area with plastic
The phenomenon that becoming larger, push up power and shared, plastic is made be not white because of the excessive appearance top of pressure and crack, can completely make plastic de-
Mould guarantees the quality of plastic.
The present invention is solved due to cooling not enough thoroughly either because the plastics after melting have certain viscosity, adherency
On the surface of lower mold cavity, thimble is too small with plastic contact area when jacking up plastic, since thimble has climbing power,
Then the pressure excessive for plastic surface is formd, the surface of plastics is squeezed, its modification is stretched, changes surface thickness at this
It is different with the thickness in other places, white convex at stretching, or even plastic bucket surface fracture can be made to crack, lead to bucket
Occur leak in use process later, or easily fragmentation the problem of, the present invention is combined with each other by above-mentioned component, is stored up
Gas in air cavity 43 is passed through inside pattern main body 462, pushes piston block 4613, and for movable screw rod 4612, rotation is provided upwards
Power, the free ball d of movable 4612 two sides of screw rod are equipped with inside pattern main body 462 in ball fixing groove b roll inside
Track sliding, jack up 4611 holding level of lid move up, molding plastic is jacked up, jack up lid 4611 have rotary force,
Will not have with molding plastic it is glutinous and, and because the contact area with plastic becomes larger, push up power and shared, make plastic will not be because of pressure
The phenomenon that strong excessive appearance top is white and cracks, completely can be such that plastic demoulds, guarantee the quality of plastic.
Above only describes basic principle of the invention and preferred embodiment, those skilled in the art can be according to foregoing description
Many changes may be made and improves, and these changes and improvements should be within the scope of protection of the invention.
