Abstract
The utility model provides a rubber injection mold, the cope match -plate pattern upper end is connected with the runner, glue injection pipe is connected to the lower extreme of runner, glue injection pipe sets up inside the cope match -plate pattern, be equipped with intermediate lever portion on the lower bolster, the partly of intermediate lever portion sets up in middle template, form the die cavity between intermediate lever portion and the middle template, glue injection pipe's terminal external connection has first exhaust passage, the bottom of die cavity is connected with the second exhaust passage, the die cavity wraps up the seal groove with the junction of second exhaust passage, the end -to -end connection of the second exhaust passage vacuum pump of bleeding, the outside of vacuum pump setting at the mould of bleeding. The beneficial effects of the utility model are that the vacuum pump of bleeding that the mould is outer is connected with the inside exhaust passage of mould, and first exhaust passage setting is in the position of runner department, can take out the air among the liquid rubber in the runner from falling, and the air that the second exhaust passage will persist in rubber is taken out from totally once more, has avoided the phenomenon that appears the bubble among the rubber component, has improved the qualification rate of producing rubber component.
Description
Technical field
This utility model belongs to rubber manufacturing technology apparatus field, especially relates to a kind of rubber injection mold.
Background technology
Rubber injection moulding machine, referred to as rubber injection machine, is a technology of rubber molded product production, is mainly used in the production of rubber molded product, for instance electrical apparatus insulation part, crash roll, sealing member etc. General Purpose Rubber mould injecting glue mode has mold pressing and a transmission note pressure two kinds, and both injecting glue modes make material glue utilization rate low, and in the production of rubber product, owing to rubber temperature in injection moulding is higher, easily there is bubble, lacks the problems such as material in product. So, all can be provided with exhaust apparatus generally in a mold, for discharging produced bubble in injection moulding. But, this exhaust apparatus make baroque rubber time, it is impossible to ensure with gas can fully and completely discharge, increase the disqualification rate of rubber.
Utility model content
The purpose of this utility model be to provide a kind of simple in construction, simple to operate, can thoroughly discharge the gas produced in mould, the rubber injection mold that production efficiency is high smoothly.
The technical solution of the utility model is: a kind of rubber injection mold, from top to bottom include cope match-plate pattern, intermediate die plate, lower bolster, the inside of described lower bolster is provided with lower bolster bed course, described cope match-plate pattern upper end is connected to cast gate, the lower end connection glue injection pipe of described cast gate, described injected rubber hose is arranged on inside cope match-plate pattern, described lower bolster is provided with intermediate shank portion, a part for described intermediate shank portion is arranged in intermediate die plate, die cavity is formed between intermediate shank portion and intermediate die plate, described injected rubber hose is connected with die cavity, the exterior end of described injected rubber hose is connected to first exhaust passage, the bottom of described die cavity is connected to the second exhaust passage, the junction environmental sealing ring recess of described die cavity and the second exhaust passage, one end of described first exhaust passage is connected with the second exhaust passage and converges, the end of described second exhaust passage connects aspirator vacuum pump, described aspirator vacuum pump is arranged on the outside of mould.
Further, the junction environmental sealing circle of described injected rubber hose and first exhaust passage.
This utility model has the advantage that and has the benefit effect that owing to adopting technique scheme, aspirator vacuum pump outside mould is connected with the exhaust passage of mould inside, in time the air having inside die cavity is detached when carrying out injection moulding, first exhaust passage is arranged on the position of cast gate, air in liquid rubber in cast gate can be detached, when injecting, the air remained in rubber is detached totally by the second exhaust passage again, avoid the phenomenon that bubble occurs in rubber, improve the qualification rate producing rubber, ensure the end product quality of rubber, in exhaust passage, seam is provided with seal groove, it is possible to further prevents air by the gap in the middle of cope match-plate pattern and lower bolster, effectively intercepts air, reach better effect.

Fig. 1 is structural representation of the present utility model.
In figure:
1, cope match-plate pattern 2, intermediate die plate 3, lower bolster
4, lower bolster bed course 5, cast gate 6, injected rubber hose
7, intermediate shank portion 8, die cavity 9, first exhaust passage
10, the second exhaust passage 11, seal groove 12, aspirator vacuum pump
13, sealing ring
Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is elaborated.
As shown in Figure 1, this utility model one rubber injection mold, from top to bottom include cope match-plate pattern 1, intermediate die plate 2, lower bolster 3, the inside of described lower bolster 3 is provided with lower bolster bed course 4, described cope match-plate pattern 1 upper end is connected to cast gate 5, the lower end connection glue injection pipe 6 of described cast gate 5, it is internal that described injected rubber hose 6 is arranged on cope match-plate pattern 1, described lower bolster 3 is provided with intermediate shank portion 7, a part for described intermediate shank portion 7 is arranged in intermediate die plate 2, die cavity 8 is formed between intermediate shank portion 7 and intermediate die plate 2, described injected rubber hose 6 is connected with die cavity 8, the exterior end of described injected rubber hose 6 is connected to first exhaust passage 9, the bottom of described die cavity 8 is connected to the second exhaust passage 10, the junction environmental sealing ring recess 11 of described die cavity 8 and the second exhaust passage 10, one end of described first exhaust passage 9 is connected with the second exhaust passage 10 and converges, the end of described second exhaust passage 10 connects aspirator vacuum pump 12, described aspirator vacuum pump 12 is arranged on the outside of mould.
Further, the junction environmental sealing circle 13 of described injected rubber hose 6 and first exhaust passage 9.
The work process of this example: the aspirator vacuum pump 12 outside mould is connected with the exhaust passage of mould inside, when carrying out injection moulding work, first exhaust passage arranges 9 in the position of cast gate 5, air times first exhaust passage 8 in liquid rubber in cast gate 5 detaches, the air remained in die cavity 8 in rubber is detached totally by the second exhaust passage 10 again, avoid the phenomenon that bubble occurs in rubber, improve the qualification rate producing rubber, it is ensured that the end product quality of rubber; It is provided with seal groove 11, it is possible to further prevent air by the gap in the middle of cope match-plate pattern 1 and lower bolster 3, effectively intercept air, reach better effect at exhaust passage seam.
Above an embodiment of the present utility model is described in detail, but described content has been only preferred embodiment of the present utility model, it is impossible to be considered for limiting practical range of the present utility model. All equalizations made according to this utility model application range change and improvement etc., all should still belong within patent covering scope of the present utility model.
