Downward through excessively upper thermal insulation board and heating plate, it is connected by heat insulation cap with cope plate inlet, when being molded, lower template and upper
Template is formed with mold cavity after carrying out matched moulds in frame, is injected into rubber with the passage in heat insulation cap by being molded import
Template inlet, the mold cavity that lower template and cope plate carry out being formed after matched moulds in frame is entered by cope plate inlet
Middle carry out injection molding.
Injection channel in the injection rebound is made up of the formed pipe being independently molded, and the corner of formed pipe is preferably
Circular shape, alleviates the resistance in passage, improves mobility.
Formed pipe both sides in the injection rebound are mounted on heating rod, and the effect of heating rod is to maintain the steady of temperature
Qualitative, its heating rod is conducive to softening the rubber in the formed pipe before start in the injection rebound of heating, under being easy to
A part as injection molded elastomer during secondary injection.
The injection rebound is that formed pipe is integrally cast with aluminum alloy materials, is easy to manufacture, also allows for improving scattered
It is hot.
Heat insulation cap is provided between the injection outlet and cope plate, makes injection rebound and mould (high by heat insulation cap
Temperature) thermal source isolation.
Beneficial effects of the present invention：It is provided with injection rebound independent in injection import, injection outlet, injection rebound
Formed pipe is provided with, shaping interface tube is connected to form injection channel, alleviated in passage with injection import, injection outlet respectively
Resistance, improves mobility.Injection outlet penetrates thermal insulation board and heating plate separately down, is injected by heat insulation cap and cope plate
Mouth is connected, and injection rebound is that formed pipe is integrally cast with aluminum alloy materials, and aluminum alloy materials enter when temperature is too high
Row quick heat radiating, then have heating rod so that injection rebound 4 in rubber be maintained at about 70 DEG C temperature, make rubber in formed pipe 44
Soft state is kept, heat insulation cap prevents the high temperature of mould from having influence on injection rebound, carries out thermal source isolation, and will not vulcanize again just
Can make in passage rubber can and the part as injection molded elastomer in injection next time, it is ensured that under the rubber energy that injection passes through the inside
Secondary to use, it is conducive to the generation for avoiding injection molding sprue material head, it also avoid manually or auxiliary machinery is carried automatically
The waste material of injection hole is taken, while not only saving raw material by this result, the operation of automation is reduced so that Machine automated change
Obtain more reliable and real.

Embodiment
It is described further with reference to Fig. 1, Fig. 2, Fig. 3, Fig. 4 and Fig. 5：
A kind of rubber injection mold device, including frame 1, lower template 2, cope plate 3, injection rebound 4, lower template 2 and upper mould
Plate 3 is carried out being formed with mold cavity after matched moulds in frame 1, and injection import 41, injection outlet 42 are provided with injection rebound 4,
Formed pipe 44 is independently arranged in injection rebound 4, the corner of the formed pipe 44 is circular shape, it, which is conducive to improving, notes
Injection Molding during modeling, the interface of formed pipe 44 forms injection channel with injection import 41, the connection of injection outlet 42 respectively, is molded by
Mouth 42 penetrates thermal insulation board 9 and heating plate 8 separately down, is connected by heat insulation cap 46 with cope plate inlet, in injection
When, lower template 2 and cope plate 3 are formed with mold cavity after carrying out matched moulds in frame 1, by the passage in heat insulation cap 46 by rubber
Cope plate inlet is injected into, enter lower template 2 and cope plate 3 by cope plate inlet is carried out after matched moulds in frame 1
The both sides of formed pipe 44 carried out in the mold cavity of formation in injection molding, the injection rebound 4 are mounted on heating rod 45, plus
The effect of hot pin 45 is to maintain the stability of temperature, and injection rebound is that formed pipe is integrally cast with aluminum alloy materials, aluminium
Alloy material carries out quick heat radiating when temperature is too high, then has heating rod so that rubber is maintained on 70 DEG C in injection rebound 4
Lower temperature, makes rubber in formed pipe 44 keep soft state, heat insulation cap prevents the high temperature of mould from having influence on injection rebound, carries out
Thermal source is isolated, and will not vulcanize can make in passage rubber can and the part as injection molded elastomer in injection next time.
