Abstract
The utility model discloses a mould with a pumping system. The mould comprises a front die, a rear die, a front die core at the center of the rear part of the front die and a rear die core at the center of the front part of the rear die, wherein the front die part is provided with a pumping channel connected with an external pumping device; primary air discharge ducts of which one end is communicated with a mould body, and secondary air discharge ducts communicated with the other ends of a plurality of primary air discharge ducts are arranged on the rear die core; the pumping channel is communicated with secondary air discharge ducts, and a sealing ring encircled on an outer ring of the rear die core is arranged on the rear die. The die core part is sealed through the sealing ring, and then the die core part is vacuumized through the pumping system, thus, flowing resistance of BMC (bulk molding compounds) plastic in the mould body can be reduced, so as to completely fill the mould and produce qualified injection parts.
Description
Technical field
The utility model relates to a kind of mould with extract system.
Background technology
In the prior art, because that the product sizing material adopts is BMC, and BMC is thermosetting plastic, mobile extreme difference, cause the mold filling difficulty, usually make at last goods produce the defectives such as notes are discontented, depression, overlap, bubble, crackle, buckling deformation, change in size, thereby how to guarantee that the quality of this finished product is puzzlement those skilled in the art's a large technical barrier.
The utility model content
The technical problems to be solved in the utility model provides a kind of mould with extract system.
Solving the problems of the technologies described above, a kind of technical scheme that the utility model adopts is: a kind of mould with extract system, comprise front mould, rear mold, be positioned at the front core rod at center, front mould rear portion and be positioned at the rear core rod of rear mold front central, described front mould partly is provided with the bleed-off passage that is connected with the air extractor of outside, be provided with the one-level air discharge duct that a plurality of ends are connected with die ontology and the secondary air discharge duct that is connected with the other end of a plurality of described one-level air discharge ducts on the described rear core rod, described bleed-off passage is connected with described secondary air discharge duct, is provided with the sealing ring that is centered around described rear core rod outer ring on the described rear mold.
Preferably, described bleed-off passage includes a transverse tube and a plurality of vertical tube, the upper end of a plurality of described vertical tubes is connected with described transverse tube, the bottom of a plurality of described vertical tubes is connected with described secondary air discharge duct, one end part seal of described transverse tube, the other end of described transverse tube is connected with the air extractor of outside.
Preferably, described vertical tube has 2.
Preferably, described bleed-off passage has 2, and setting parallel to each other.
Preferably, be not communicated with mutually between a plurality of described one-level air discharge ducts.
Preferably, described secondary air discharge duct is connected with all described one-level air discharge duct, and described secondary air discharge duct forms closed pipeline.
Because technique scheme is used, the utility model compared with prior art has following advantages: by sealing ring the mould heart is partly sealed, by extract system the mould heart is partly vacuumized again, thereby can reduce the resistance that the BMC plastic cement flows in die ontology, thereby can mold filling complete, produce qualified moulding.
