Specific embodiment
In order that the purpose of this utility model, technical scheme and advantage become more apparent, below in conjunction with accompanying drawing and implementation
Example, is further elaborated to the utility model.It should be appreciated that specific embodiment described herein is only used to explain
The utility model, is not used to limit the utility model
It is as Figure 1-4 a specific embodiment of the present utility model：A kind of injection mold of side forming through holes, bag
Include mavable module core 1, fixed mold core 2, side through hole sliding block 3, the profiling punch-pin 1-1 being arranged in mavable module core 1 and be arranged in fixed mold core 2
Profiling die cavity 2-1, the side through hole sliding block 3 is provided with some taper cores 5 towards the side of profiling punch-pin 1-1, described
The tip radius of taper core 5 are less than bottom radius, and the profiling punch-pin 1-1 is provided with and coordinates with the taper gap of taper core 5
Tapered hole 6, the overflow edge value of the gap less than plastic cement of the taper core 5 and tapered hole 6.
It is preferable to carry out as one kind, the mavable module core chute 1-2 that the mavable module core 1 is provided with, the fixed mold core 2 is provided with fixed
Die chute 2-2, the mavable module core chute 1-2 and fixed mold core chute 2-2 cooperatively form the cunning slided for side through hole sliding block 3
Road.
Used as being further preferable to carry out, the side through hole sliding block 3 is two sliding blocks being symmetrical set.
Used as being further preferable to carry out, the end of taper type core 5 is corresponding to profiling punch-pin 1-1 on side through hole sliding block 3
The gap of 0.2~0.3mm is left on the wall of side between the bottom of tapered hole 6.
It is preferable to carry out as one kind, the taper of the taper core 5 is more than 3 °.
Used as being further preferable to carry out, the injection mold also includes the side for other edge formings of plastic cement products
Sliding block 24.
Workflow of the present utility model is：Injection matched moulds during, first control mavable module core 1 move, make its with
Fixed mold core 2 is fastened, then slides side through hole sliding block 3 by external force, make side through hole sliding block 3 along mavable module core chute 1-2 and
The slideway that fixed mold core chute 2-2 is formed is slided, until in the tapered hole 6 on the wall of the insertion profiling punch-pin 1-1 of taper core 5 sides.
As the insertion depth of taper core 5 gradually increases, tapered hole 6 gradually increases the lateral pressure of taper core 5, makes taper core
Friction between 5 side walls and the side wall of tapered hole 6 gradually increases.The frontal impact for so allowing for side through hole sliding block 3 is converted into
Frictional force on the circumferencial direction of taper core 5 with tapered hole 6, until the stop motion of side through hole sliding block 3, now taper core 5
End and the bottom of tapered hole 6 between leave the gap of 0.2~0.3mm, and the side wall of taper core 5 and the side wall of tapered hole 6 it
Between overflow edge value of the gap less than plastic cement, wherein mavable module core 1, fixed mold core 2 and side through hole sliding block 3 enclose to form injection moulding plastic product
The forming cavity of product.The situation of the fracture of taper core 5 so can be both greatly reduced, while in turn ensure that the position of taper core 5
Zero deflection, makes punch position on each plastic cement products shell accurate, errorless.
Fig. 5-7 is another embodiment of the present utility model, and the difference with upper one embodiment is：The side
Side through hole sliding block 3 is towards being additionally provided with the cylinder core 7 that is abutted against with profiling punch-pin 1-1 sides wall on the side of profiling punch-pin 1-1.Institute
State cylinder core 7 and be uniformly arranged on side through hole sliding block 3 towards on the side of profiling punch-pin 1-1.
The workflow of the present embodiment is：In side through hole sliding block 3 towards uniform in addition on the side of profiling punch-pin 1-1
Cylinder core 7 is set, during the matched moulds of injection, when in the insertion tapered hole 6 of taper core 5 on side through hole sliding block 3 and
When depth gradually increases, tapered hole 6 gradually increases the lateral pressure of taper core 5, the side wall of taper core 5 and the side of tapered hole 6
Friction between wall gradually increases, and the movement velocity of side through hole sliding block 3 can gradually slow down.Now cylinder core 7 start with
Profiling punch-pin 1-1 sidewall contacts, until the stop motion of side through hole sliding block 3, so by cylinder core 7 and profiling punch-pin 1-1
The distance holding abutted against between the side and profiling punch-pin 1-1 sides wall that can ensure side through hole sliding block 3 everywhere is equal, makes note
Thickness is uniform everywhere for the plastic cement products side wall that modeling is obtained.
Although reference be made herein to multiple explanatory embodiments of the present utility model are described to the utility model, but,
It should be understood that those skilled in the art can be designed that a lot of other modification and implementation methods, these are changed and implementation method
To fall within spirit disclosed in the present application and spirit.More specifically, in disclosure, drawings and claims
