There are a large amount of gases, particularly summarize a large amount of gases in the end of material flowing.At present, existing compression mold because
It is bad so as to cause to be vented using passive exhaust mode, trapped gas phenomenon often occurs, cause product produce lack of fill, lack material,
The problems such as burning.
The content of the invention
It is an object of the invention to provide a kind of Vacuuming structure of compression mold, and it can be in product molding process
It is middle to be quickly drawn out caused gas in mold cavity, to solve to be vented bad make existing for compression mold in the prior art
Into trapped gas the problem of.
To use following technical scheme up to this purpose, the present invention：
A kind of Vacuuming structure of compression mold, it includes the upper die and lower die being equipped with, in the upper mould
It is provided with upper mold core at the heart, the corresponding upper mold core is provided with down in being provided with die cavity, the bottom of the die cavity on the lower mould
Die, wherein, the bottom of the upper mould is provided with seal sleeve, and lower mould external diameter described in the minor diameter fit of the seal sleeve is set
Put, be provided with refractory seals part between the lower mould and seal sleeve, will be upper by seal sleeve during the Ccope closing machine
Cavity between mould and lower mould is sealed, and the first evacuation passageway is offered at the top of the seal sleeve, and described first takes out
Vacuum passage connects the first vacuum extractor by connector, and the bottom of the lower mould offers what is connected with the mold cavity bottoms
Second evacuation passageway, second evacuation passageway connect the second vacuum extractor by connector.
Especially, the mating surface between the die cavity and lower die offers several air discharge ducts, is opened on the lower die
Provided with the connectivity slot for connecting several described air discharge ducts, second evacuation passageway connects through the lower die and die cavity
It is logical.
Especially, the connector uses attaching nut.
Especially, some leads are provided between the upper die and lower die.
Especially, it is provided between the bottom surface of the lower die and the lower mould in the periphery of second evacuation passageway
Refractory seals part.
Especially, the refractory seals part is thermostable fluorine silicon rubber loop.
Beneficial effects of the present invention are that the Vacuuming structure of the compression mold is applied in heat compared with prior art
Gu on the product of material BMC, SMC moulding compound compression forming, not only design structure is reasonable, and processing technology is simple.And production
The bright and clean basic zero defect of product surface, product inherent quality is uniform, and compactness is good, has passed through industrial frequency withstand voltage test requirements document.Avoid
Because being vented the trapped gas phenomenon of bad appearance, job efficiency and quality requirements are improved, the consistent favorable comment of client is obtained.
