Description
Technical field
The present invention relates to the injection mo(u)lding field of water knockout drum, particularly a kind of injection molding forming method of plastics water knockout drum.
Background technology
At present, the use of water knockout drum is extensive, and is of a great variety, and main product has copper water knockout drum, rustless steel water separator, copper plastics water knockout drum etc. on the market.Mainly rustless steel water separator is mainly by after stainless steel material assembly unit or the solid forging by copper for the copper water knockout drum, and by machining seal with screwed joint (viscose glue mode), the joint ball valve of bleeder branch road partly assembles.
These two kinds of water knockout drum occupation rates of market are very high, but in use are prone to quality problems such as the cracking that leaks; And whole water knockout drum comprises and being responsible for and its accessory copper filter and copper ball valve, all is source of heat releases, is not incubated, easily dewfall, heat loss greatly, waste energy; The above problem causes the plastics water knockout drum more and more to obtain people's attention.Because plastics have light weight, corrosion-resistant, the characteristics of not adsorbing incrustation scale, insulation, non-dewfall, and the plastics water knockout drum person in charge can be integrated with bleeder branch road ball valve and joint, promptly make it integrated welding by injection mo(u)lding, its long service life and production efficiency all are improved.Therefore, the advantage of plastics water knockout drum is conspicuous.
Using more plastics water knockout drum at present is that copper is moulded water knockout drum, in its production process, mainly is by injection mold and mold insert (return connector) single injection-molded that is embedded in the die cavity.Advantage is that the product that injection moulding is come out is that the person in charge and return connector are an integral body, and being different from the traditional copper water knockout drum need be threaded, and saves assembling procedure, and reduces the tie point that leaks; But there is following shortcoming in one-shot forming: in the process of injection moulding, the person in charge's bleeder moulding needs mandrel, before the die sinking, must loose core; If the bleeder is many and the person in charge is longer, not only stroke is big and the consumption time is long for the process of loosing core, and damages the end face circularity of being responsible for easily in the process of loosing core, and is unfavorable for being connected with the follow-up of other auxiliary equipments.
In sum, there is following deficiency in the method for the single injection-molded of plastics water knockout drum at present: the process of, loosing core complexity, and the fragile person in charge's end face circularity is unfavorable for being connected with the follow-up of other auxiliary equipments; Two, in being threaded of water knockout drum and mold insert, because of exist the gap easily infiltration leak.
Summary of the invention
The objective of the invention is to overcome above-mentioned the deficiencies in the prior art, provide a kind of being beneficial to cooperate and reduce the leak injection molding forming method of plastics water knockout drum of possibility of infiltration.
For reaching above-mentioned purpose, the technical solution used in the present invention is: a kind of injection molding forming method of plastics water knockout drum, and process respectively earlier and be responsible for and metal joint, by quadric injection mould, both are shaped to one then.
Particularly, described quadric injection mould is that first injection-molded plastic is responsible for, and reserves or offer the water knockout drum installing hole, metal joint is placed in this installing hole again, at last this installing hole is carried out injection moulding once more, and plastics are responsible for and metal joint moulding one.
Further, the described injection molding forming method utilization person in charge, metal joint and injecting molding die are finished, and injecting molding die comprises front mould, front mould core rod, back mould, back mould core rod and ejector, and this quadric injection mould may further comprise the steps:
1) at first, the described person in charge goes up and bores the water knockout drum installing hole, and removes the installing hole particularly dirty Material-of-the-active and the dust in aperture;
2) secondly, described mold insert outer surface wraps encapsulate, and it is inserted on the bleeder mandrel of back mould core rod;
3) again, described bleeder mandrel end is by the water back that is threaded, threaded together;
4) then, the installing hole position of being responsible for is preheated, be partly dissolved near the sizing material of installing hole; Then it is inserted in the die cavity of back mould core rod, and installing hole and water back one a pair of on;
5) last, described front and back mould is lumped together; Connect power supply, heat the inner heating rod that is provided with of described water back; Inject the fusion sizing material by the feeding mouth that is arranged on the front mould, described fusion sizing material injects die cavity by runner; Near the sizing material of fusion fusion fusion sizing material that injects and the installing hole, and wrap mold insert, go out the plastics water knockout drum by the die cavity somatotype;
6) after above-mentioned steps was finished, the front and back mould separated, and ejector ejects plastics water knockout drum integral body, and an injection cycle action is finished.
Preferably, the installing hole described in the step 1) is no less than 1.
Preferably, the time that preheats described in the step 3) is 30-50 second.
Preferably, the described ejector described in the step 6) comprises push pedal, thimble and back-moving spring external member, and an end of described thimble and back-moving spring external member is located on the mould of back, and the other end connects push pedal.
The present invention has following beneficial effect with respect to prior art:
1, the injection molding forming method of plastics water knockout drum of the present invention in the process of loosing core, guarantees the person in charge's end face circularity, is beneficial to the follow-up of other auxiliary equipments to be connected;
2, the injection molding forming method of plastics water knockout drum of the present invention, water knockout drum and the moulding of mold insert integral molded plastic be not because of existing the gap to reduce the possibility that infiltration is leaked in cooperating;
3, the injection molding forming method of plastics water knockout drum of the present invention, as early as possible the position, bleeder of tubing is preheated 30～50 seconds before the injection moulding, near the bleeder sizing material part, the abundant fusion of the outer encapsulate of bleeder and metal joint when guaranteeing follow-up moulding improves the intensity and the sealing property of the product of producing.
