Description

Injection mould

Technical Field

The utility model relates to a stationery mold processing, in particular to injection mold.

Background

Injection molding is a tool for producing plastic products and also for giving the plastic products complete structure and precise dimensions, and injection molding is a processing method used for mass production of parts with complex shapes. Specifically, the plastic melted by heating is injected into a mold cavity from an injection molding machine at high pressure, and a formed product is obtained after cooling and solidification.

The existing injection mold generally comprises an upper mold and a lower mold, a mold cavity is formed between the upper mold and the lower mold, a pull rod mounting plate is fixedly arranged on the upper mold, a pull rod which penetrates through the upper mold and is connected with the lower mold is mounted on the pull rod mounting plate, and an injection molding opening communicated with the mold cavity is formed in one surface of the lower mold, which faces back to the upper mold. The linkage between the upper die and the lower die is realized through the arrangement of the pull rod, so that the moving upper die can drag the lower die to move through the pull rod, a certain distance is pulled between the lower die and the equipment through the pull rod, and the distance pulled is used for cleaning waste materials on an injection molding port.

Because the stroke that opens and shuts of injection molding machine is limited, and the setting of pull rod mounting panel has increased injection mold's whole thickness in the current mould to lead to pulling open the distance between lower mould and the equipment to receive the restriction, make the staff can't carry out convenient clearance to the waste material on the mouth of moulding plastics.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing an injection mold, this injection mold volume is smaller and more exquisite to realize the convenient clearance to the mouth of moulding plastics upper waste material.

The above technical purpose of the present invention can be achieved by the following technical solutions: the utility model provides an injection mold, includes mould and lower mould, constitute the die cavity between last mould and the lower mould, the mouth of moulding plastics of intercommunication die cavity is seted up to the one side of going up the mould dorsad to the lower mould, it can drive the one-way linkage component that the lower mould removed to be connected with between last mould lateral wall and the lower mould lateral wall to make to go up the mould, works as go up the mould and remove and form between the two when opening the interval, it removes to go up the mould through one-way linkage component drive lower mould.
