Description
Technical field
The utility model relates to a kind of injection mold, in particular to a kind of mould inscribe mold.
Background technique
Currently, plastic cement products are many kinds of, such as decorative product and consumer electronics product, plastic cement products usually pass through mould
Has injection molding.
In existing molding production, cast gate material head is generally all had by mold product after molding, as shown in Figure 1, through passing
The reason of injection molding manner of system product 9 after molding, usually has circular cast gate material head 90, the cast gate material head 90 formation
To remain in the plastics of the melting in running channel to be connected with molded product in mold cavity, it is cooling after be integrated.And required production
As shown in Fig. 2, i.e. after injection molding, people also need to remove cast gate material head 90 product, to process aperture 94.
Traditional injection moulding mode causes one of NC of palpus increase after every formed product to go material head processing technology, and this process bands
There are many uppity risks, product higher for some appearance requirements easily causes mirror surface when milling material head such as mirror surface product
It scratches, and the protective film of mirror surface needs to tear and re-replaces new after milling material, milling cutter mouth stress is crossed conference and made during milling material head
Make Jiao Kou whiting, etc..This causes the output fraction defective of product in production process high, substantially increases manufacturing cost.
Cropping technology is typically only capable to using side by the way of glue in mould in the prior art, automatic to cut off pouring for side
Mouthful, and the material head of tapping as shown in Figure 2 can not then be handled.
In addition, the product 9 (such as Fig. 1 and Fig. 2) with back-off 91 can be often encountered in the prior art, when being opened ejecting product
It is easy to draw bad back-off 91, though mold in the prior art has the mechanism of some trippings, it can be difficult to guaranteeing complete in ejecting product
Back-off 91 is not pulled entirely, this can affect to the quality of product 9；Moreover, tripping mechanism in the prior art is usual
Structure is complicated, to increase die cost.
Utility model content
The purpose of this utility model is that in view of the above-mentioned drawbacks in the prior art, providing a kind of mould inscribe mold, energy

To realize above-mentioned purpose of utility model, the utility model adopts the technical scheme that a kind of mould inscribe mold,
Including master mold, male model and the ejecting mechanism being installed in the male model, the master mold and the male model cooperatively form type chamber, institute
The intracavitary molding product of the type can be ejected by stating ejecting mechanism, and the master mold is provided with the cast gate communicated with the type chamber, institute
It states male model and offers the mounting hole communicated with the type chamber, the mould inscribe mold further includes material cutting mechanism, the material cutting mechanism
Including sliding the outer knife that is coupled in the mounting hole, the outer knife is oppositely arranged with the cast gate, can under external force on
Row cuts off the material head formed in the cast gate.
In addition, the utility model also proposes following attached technical scheme:
The outer knife is provided with cutting edge, and the peripheral shape of the cutting edge is consistent with the opening of the product.
The material cutting mechanism further includes the oil cylinder being fixed on the male model, and the oil cylinder, which provides, drives the outer knife uplink
External force.
The material cutting mechanism further includes upper mobile board interconnected and lower movable plate, the upper mobile board and lower movable plate
It is connected with the outer knife.
The male template offers the accepting hole that can accommodate the upper mobile board and lower movable plate.
The material cutting mechanism further includes the interior knife being arranged in the outer knife, and the interior knife is connected with the ejecting mechanism.
The ejecting mechanism includes upper plate and lower roof plate interconnected, and the interior knife is by the upper plate and lower roof plate
Cooperation is fixed.
The material cutting mechanism further includes the thimble being arranged in the interior knife, and the thimble and the male model are connected.
The end of the outer knife, interior knife and thimble cooperatively forms groove.
The end of the thimble is provided with the plush copper protruded into the groove, that end of the plush copper towards the cast gate is big
In that end being connect with the thimble.
Compared with the prior art, utility model has the advantages that
1., can be before the intracavitary plastics solidification of type by gate cutting, after product ejection, material head by being provided with cutter assembly
With product energy delamination, increases the process for removing material removal head without subsequent, accelerate production efficiency, reduce human cost；
2. cast gate is automatically cut off in mold, as a result, the consistent part of exterior quality, and traditional pass through subsequent machine
