Description
Technical field
This utility model is related to technical field of mold, particularly to a kind of injection mold that can automatically excise stub bar.
Background technology
Injection production process in, molten plastic by running gate system enter mold cavity, connection injection machine and die cavity this
One section of plastics is referred to as stub bar.For the product of batch production, general stub bar can be linked together with product, needs by rear processing
Operation is made a return journey material removal head, thus this needs to increase manpower during rear processing, to carry out stub bar using manual operations
Remove, which increase production cost, also can there is the risk of scratching products simultaneously in the operation of rear processing.
Utility model content
For solving above-mentioned technical problem, the purpose of this utility model is to provide a kind of injection mould that can automatically excise stub bar
Tool, can automatically cut off stub bar in die sinking, reduce human cost, decrease the generation of the problem in rear manufacturing procedure.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, this utility model is achieved through the following technical solutions: one
Plant the injection mold that can automatically excise stub bar, including front mould and rear mold, this front mould includes panel and front template, and this rear mold includes bottom
Plate, two support blocks being vertically installed on front side of base plate, the board being horizontally placed on two support blocks and be located at board on
Rear pattern plate, is provided with top board between two support blocks, top board is provided with thimble, be provided with front cavity, in rear pattern plate in described front template
Be provided with rear cavity, front cavity and rear cavity cooperatively form injection die cavities, described thimble sequentially pass through forward board, rear pattern plate and after
Die, passes through mechanical shutter and connects, described board is provided with the edge of a knife and enters son, and this edge of a knife enters between described front template and rear pattern plate
Son advances through rear pattern plate and rear cavity, and the end that the edge of a knife enters son is stretched in injection die cavities, and described board is further fixed on a control
Screw processed, is provided with the shoulder hole being made up of large diameter hole and small diameter bore in rear pattern plate, this control screw penetrates the rank of rear pattern plate
In terraced hole, control the head of screw to be located in large diameter hole, and the height of large diameter hole is more than the height of the head controlling screw.
The beneficial effects of the utility model are: the rear pattern plate in this utility model is due to by mechanical shutter and front template
Connect, thus when molding first time, rear pattern plate and front template geo-stationary, the board in rear mold is moved rearwards by, and the edge of a knife enters son
It is moved rearwards by with respect to product, thus the edge of a knife of movement enters son and can cut off stub bar, realize stub bar and product separation.Control spiral shell
Behind the bottom of large diameter hole that the head of silk is resisted against rear pattern plate, in the presence of controlling screw, rear pattern plate is with board and whole
Rear mold is moved rearwards by, and completes second die sinking, and thimble can be with ejecting product.This utility model can be during die sinking, profit
Enter son with the edge of a knife and complete the cut-out to stub bar, artificial removal's stub bar need not be passed through in subsequent handling, save total system of product
The time of journey, reduce production cost, and the generation of the various problems in manufacturing procedure after can also reducing.
Brief description
Fig. 1 is the structural representation in matched moulds state for this utility model.
Fig. 2 is the structural representation when molding first time for this utility model.
Fig. 3 is the structural representation when molding for second for this utility model.
Fig. 4 is the structural representation when product is ejected for this utility model.
Specific embodiment
Below in conjunction with the accompanying drawings preferred embodiment of the present utility model is described in detail, so that advantage of the present utility model
Can be easier to be readily appreciated by one skilled in the art with feature, thus make apparent clear and definite to protection domain of the present utility model
Define.
As shown in Figures 1 to 4, a kind of injection mold that can automatically excise stub bar, including front mould and rear mold, this front mould includes
Panel 1 and front template 2, this rear mold includes base plate 3, two support blocks 4 being vertically installed on base plate 3 front side, is horizontally placed on two
Board 5 on individual support block 4 and the rear pattern plate 6 being located on board 5, are provided with top board 7, top board 7 are provided between two support blocks 4
Thimble 8, is provided with front cavity 9 in described front template 2, is provided with rear cavity 10 in rear pattern plate, and front cavity 9 and rear cavity 10 cooperatively form
Injection die cavities, described thimble 8 sequentially passes through forward board 5, rear pattern plate 6 and rear cavity 10, described front template 2 and rear pattern plate 6 it
Between connected by mechanical shutter 11, described board 5 is provided with the edge of a knife and enters son 12, and this edge of a knife enters son 12 and advances through rear pattern plate 6
With rear cavity 10, the end that the edge of a knife enters son 12 is stretched in injection die cavities, and described board 5 is further fixed on a control screw 13, after
It is provided with the shoulder hole 601 being made up of large diameter hole and small diameter bore, this control screw 13 penetrates the ladder of rear pattern plate 6 in template 6
In hole 601, control the head of screw 13 to be located in large diameter hole, and the height of large diameter hole is more than the head controlling screw 13
Highly.
During work, mold product by the injection die cavities of this injection mold, then, as shown in Fig. 2 rear mold is moved back by
Dynamic, because front template 2 and rear pattern plate 6 pass through mechanical shutter 11 and connect, the rear pattern plate 6 in rear mold is static with respect to front template 2,
The edge of a knife enters son 12 and is moved rearwards by with respect to the rear cavity 10 in rear pattern plate 6 and rear pattern plate 6, thus the edge of a knife of movement enters son 12 and cuts
