Function avoids note rubber equipment exhaust, so that rubber overflow be avoided to generate overlap.The present invention is suitable for automobile chassis shock absorbing bushing
Class product solves the problems, such as the deburring of shock absorbing bushing class product in rubber mold, it is ensured that non-trimming after such product depanning is saved
Rubber material and artificial, improves the utilization rate and production efficiency of sizing material.
Detailed description of the invention
Fig. 1 is a kind of schematic diagram of internal structure of the rubber mold of bushing non-trimming structure；
Fig. 2 is a kind of fractionation schematic diagram of the rubber mold of bushing non-trimming structure.
Specific embodiment
In order to make the present invention more obvious and understandable, hereby with preferred embodiment, and attached drawing is cooperated to be described in detail below.
The present invention is a kind of rubber mold of bushing non-trimming structure, as shown in Figure 1 and Figure 2 comprising cope plate 6, upper mold
The top of plate 6 is equipped with runner plate 3, and stripper 4 and spring 5 are equipped between cope plate 6 and runner plate 3；Spring 5 is set to and is distributed in
In groove around template 6；Stripper 4 is set to the middle position of cope plate 6.The bottom of cope plate 6 passes through middle template 9 and lower die
Plate 16 connects, and the bottom of cope plate 6 is equipped with upper groove, and the bottom of lower template 16 is equipped with lower groove, divides in upper groove and lower groove
Not She You upper mold mold insert 8 and lower die mold insert 11, upper mold mold insert 8 is fixed on cope plate 6 by upper mold positioning pin 2；Lower die mold insert
11 are fixed in lower template 16 by lower die positioning pin 13.Bushing 12 are equipped in lower die mold insert 11.Upper mold mold insert 8, lower die mold insert
The type chamber of bushing product 10 is equipped between 11 and middle template 9, cope plate 6 is equipped with material hole 1, the top runner plate 3 of material hole 1
It connects, it is intracavitary that material hole 1 from the top of cope plate 6 is through to type, and cope plate 6 is equipped with exhaust system, and exhaust system is from upper mold
It is intracavitary that the top of plate 6 is through to type.Exhaust system includes relief hole 7, and it is intracavitary that relief hole 7 from the top of cope plate 6 is through to type,
