Technical field
The utility model relates to injection forming mold field, especially a kind of mold that can be fervent in internal realization cast gate.
Background technique
Using injection forming mold carry out product injection molding produce when, some using PMMA material product,
Molding gate is relatively thick, and there are certain difficulties when this will lead to shearing pouring gate after shaping.Traditional side gate shearing
Mode, such as the cutting of laser cutting, jig etc., all can cause the post-processing of product bad.It just needs to undesirable sometimes in this way
Workpiece carries out the operations such as repairing processing, improves whole production cost, extends the process of product processing, and will lead to production
Inefficiency.Therefore a kind of method or apparatus for being able to solve the above problem is needed now.
Summary of the invention
The utility model is to propose that a kind of structure is simple to solve above-mentioned deficiency present in the prior art, and design is skilful
It is wonderful, it is rationally distributed, the mesh of production efficiency can be improved to reach reduction production cost in the cutting that mould inside carries out cast gate
Mold.
The technical solution of the utility model is: a kind of to realize the fervent mold of cast gate, the mold in inside
Including fixed clamping plate 1, the lower section of fixed clamping plate 1 is provided with A plate 2, and fixed die insert 3 is provided in A plate 2, and the mold also wraps
Moving clamping plate 4 is included, the moving clamping plate 4 has been sequentially arranged above bottom needle plate 5, face needle plate 6, square iron 7 and B plate 8, the B plate 8
Inside be provided with moving die insert 9, and the fixed die insert 3 and moving die insert 9 can in molding shape forming cavity, it is characterised in that:
Type core mandril 10, the top of type core mandril 10 and 11 phase of dynamic mould core being located in moving die insert 9 are connected on the bottom needle plate 5
Even, oil cylinder 12 is additionally provided in bottom needle plate 5, the working end of the oil cylinder 12 and activity, which are worn, to be connect in face needle plate 6, square iron 7 and B plate
Connecting rod 13 in 8 is connected, and the top of connecting rod 13 is provided with reduction platform 14, is provided with cast gate cutter 15 in the reduction platform 14
It is contacted with the top of reset spring 16, the reset spring 16 with the bottom of moving die insert 9, the connecting rod 13 and cast gate cutter 15
Central axes be parallel to each other, and the central axes of the two and vertical direction are in 3-8 ° of angle, the sword on 15 top of cast gate cutter
Match at portion and the cast gate on dynamic mould core 11.
The utility model compared with the existing technology, has the advantages that
The mold that can be fervent in internal realization cast gate of this kind of structure type, simple in sturcture, ingenious in design, layout is closed
Reason, it the problems of when preparing the thicker workpiece of molding gate, is added for traditional injection moulding mold in the inside of mold
A set of cutter mechanism, creatively improves cast gate cutting mode, obtains a kind of in mould inside hot cutting pouring gate
Mould structure.It can in the end that product is injected, be not opened before, in resin material completely cooling and relatively soft
The cutting of cast gate is carried out under state, this mode removes issuable unfavorable condition when cast gate after capable of effectively avoiding molding,
And reduce production cost；The process that product processing can also be reduced simultaneously, shortens the overall processing time of product, improves production effect
Rate.And its manufacture craft is simple, and manufacturing cost is cheap, it can be said that it has a variety of advantages, particularly suitable for
It is promoted and applied in this field, market prospects are very wide.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model embodiment.
Specific embodiment
Below in conjunction with Detailed description of the invention specific embodiment of the present utility model.One kind can be realized in inside as shown in Figure 1:
The fervent mold of cast gate, the mold include fixed clamping plate 1, and the lower section of fixed clamping plate 1 is provided with A plate 2, is provided in A plate 2
Fixed die insert 3, the mold further include moving clamping plate 4, and the moving clamping plate 4 has been sequentially arranged above bottom needle plate 5, face needle
Plate 6, square iron 7 and B plate 8 are provided with moving die insert 9 in the B plate 8, and the fixed die insert 3 and moving die insert 9 can close
Shape forming cavity when mould, is connected with type core mandril 10 on the bottom needle plate 5, the top of type core mandril 10 be located at moving die insert 9
Interior dynamic mould core 11 is connected, and oil cylinder 12 is additionally provided in bottom needle plate 5, and the working end of the oil cylinder 12 and activity, which are worn, to be connect in face
Connecting rod 13 in needle plate 6, square iron 7 and B plate 8 is connected, and the top of connecting rod 13 is provided with reduction platform 14, in the reduction platform 14
It is provided with cast gate cutter 15 and reset spring 16, the top of the reset spring 16 is contacted with the bottom of moving die insert 9, the company
The central axes of bar 13 and cast gate cutter 15 are parallel to each other, and the central axes of the two and vertical direction are in 3-8 ° of angle, described to pour
Match at the blade and the cast gate on dynamic mould core 11 on 15 top of mouth cutter.
The utility model embodiment can realize that the course of work of the fervent mold of cast gate is as follows in inside: in molding machine
Under drive, dynamic model part is whole towards cover half componental movement, until fixed die insert 3 and moving die insert 9 mutually molding shape forming cavity；
The material of molten condition is perfused into type chamber for molding machine, forms product after material is cooling；
After material forming, before die sinking, control system can control the movement of oil cylinder 12, and oil cylinder 12 drives connecting rod 13 along own axes
It moves upwards, and then drives the blade on 15 top of cast gate cutter to cutting at the cast gate of product after molding, due at this time
Resin material is completely cooling not yet, and hardness is relatively low, therefore can quickly and swimmingly realize the cutting of cast gate；
When oil cylinder 12 does ejection movement, reset spring 16 is compressed, and after the completion of cutting action, 12 pressure release of oil cylinder,
Under the action of reset spring 16, connecting rod 13 and cast gate cutter 15 all can be moved downward oppositely, initial position be returned to, under waiting
Cutting operation；
After cutting, molding machine drives dynamic model part downlink, since the process of entire cast gate cutting is all in mould inside
It completes, therefore the mandril of demoulding directly ejects product after die sinking, product can be removed from the molds by operator.
