Abstract
The utility model discloses an injection mold which is characterized in that the injection mold comprises a front mold, a front mold core, a rear mold, a rear mold core and an ejector, wherein the rear mold core is arranged in the rear mold, the ejector is arranged outside the rear mold, and a mold insert placing chamber and a pipe fitting placing chamber are sequentially and perpendicularly arranged in the rear mold core. When the injection mold is in a working state, the front mold core and the rear mold core are closed together to form the integral pipe fitting placing chamber; and a heating rod wire access passage is arranged in the rear mold, the mold insert placing chamber is provided with a bleeder core shaft, the end of the bleeder core shaft is connected with a heating pipe and a heating rod is arranged in the heating pipe. In the process of injection molding, since a secondary injection molding method is adopted, the core pulling process after the completion of injection molding is simplified, the roundness of the end surface of a main pipe is guaranteed and the subsequent connection of other accessories is facilitated; and moreover, since the main pipe is integrated with a metal joint, the threaded connection is not required for the main pipe and the metal joint, and the probability of water seepage and leakage at the connection point is reduced.
Description
Technical field
The utility model relates to the injection moulding field of water knockout drum, particularly a kind of injection-type mould.
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 injection forming mold 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.
The utility model content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, provides a kind of being beneficial to cooperate and reduce the leak injection forming mold of possibility of infiltration.
For reaching above-mentioned purpose, the technical solution adopted in the utility model is: a kind of injection forming mold, comprise front mould, front mould core rod, back mould, back mould core rod and ejector, back mould core rod is located in the mould of back, and ejector is located at outside the mould of back, back mould core rod inside is provided with the mold insert placed cavity, be provided with the bleeder mandrel in the described mold insert placed cavity, the terminal heating pipe box that connects of bleeder mandrel, front and back mould core rod lumps together, form the pipeline placed cavity, and the spiral injection channel that is communicated with the mold insert placed cavity.
Preferably, be provided with heating rod in the described heating pipe box, be provided with heating rod electric wire Vomitory in the mould of described back.
Preferably, described heating pipe box is an aluminum heating pipe box.
Preferably, described ejector 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 utility model has following beneficial effect with respect to prior art:
1, injection forming mold described in the utility model 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, injection forming mold described in the utility model, 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 ejector structure of injection forming mold described in the utility model is convenient to resetting of back mould and separating of back mould and injection molding part, and is simple in structure, convenient durable.
