Abstract
The invention provides an injection-molding device comprising a mold and an injection nozzle, wherein, the mold comprises a mold body and a mold holder; an injection channel is arranged in the mold body; the mold holder comprises a bushing, a groove is formed on the mold holder, and the bushing is fixed in the groove; an injection opening is formed at the end adjacent to the mold body in the bushing and communicated with the injection channel of the mold body; screwing-in screw teeth are formed on the circumferential surface in the bushing; the injection nozzle comprises a nozzle head, a leakage-proof gasket ring and a fixing seat; threads formed on the outer surface of the nozzle head, and the threads are meshed with the screwing-in screw teeth; the leakage-proof gasket ring is located between the threads and the fixing seat and fixed to the fixing seat. When molding materials are injected into the mold, the injection nozzle is screwed into the bushing by using the threads of the injection nozzle and the screwing-in screw teeth of the bushing; meanwhile, the opening of the bushing is plugged by the leakage-proof gasket ring, and then, the molding materials are injected into the mold by the injection nozzle, thereby preventing the molding materials from seeping from the injection opening.
Description
Technical field
The present invention relates to a kind of device for injection moulding.
Background technology
When accurate object of moulding or thin part, understand ejection formation under the condition of high-voltage high-speed usually at present.The injection nozzle of present device for injection moulding generally presents circular arc; It is not tight that the nozzle of circular arc and the inlet of mould generally contact, and has the slit, under high-voltage high-speed; Owing to penetrate kick; Injecting the mould material can ooze out from the slit, even causes injection nozzle from mould, to rebound out, thereby influences shaping finished product.
Summary of the invention
In view of this, be necessary to provide a kind of and can avoid in the ejection formation process device for injection moulding that the mould material oozes out from inlet.
A kind of device for injection moulding, it comprises mould and injection nozzle, said mould comprises die body and die holder, and an injection channel is arranged in the said die body; Said die holder comprises a lining, forms a groove on the said die holder, and said lining is fixed in the groove; Said bush inside has an inlet near die body one end, and said inlet communicates with the injection channel of die body, has the screw-in thread on the inner circumferential surface of said lining; Said injection nozzle comprises a shower nozzle, antidiarrheal gasket ring and holder, and said showerhead outer surface forms screw thread; Said screw thread is meshed with said screw-in thread, and said antidiarrheal gasket ring and is fixed on the holder between screw thread and holder.
Said device for injection moulding utilizes the screw thread of injection nozzle to be meshed with the screw-in thread of bush inside, and injection nozzle is screwed in the lining, utilizes the antidiarrheal gasket ring to block the lining opening simultaneously, carries out ejection formation then.Thereby preventing to inject the mould material oozes out from inlet.
Description of drawings
The device for injection moulding decomposing schematic representation that Fig. 1 provides for embodiment of the present invention.
The device for injection moulding combination sketch map that Fig. 2 provides for embodiment of the present invention.
The specific embodiment
To combine accompanying drawing below, the present invention will be done further detailed description.
See also Fig. 1, the present invention provides a kind of device for injection moulding, and it comprises mould 10, injection nozzle 20.This injection nozzle 20 can be connected with mould 10, will inject the mould material and be injected into said mould 10.
See also Fig. 2, said mould 10 comprises die body 11 and die holder 12.One injection channel 110 is arranged in the said die body 11.Said die holder 12 comprises lining 120 and locating ring 121.Form a groove 122 on the said die holder 12, in the said locating ring 121 fixedly embedded grooves 122 on said die holder 12.Said lining 120 places locating ring 121, is fixedly connected with locating ring 121.Through said locating ring 121 said lining 120 is fixed on the said die holder 12.Said lining 120 inner packet explanatory notes in brackets inlet 1200 and screw-in thread 1201.Said inlet 1200 is positioned at lining 120 and communicates near an end of die body 11 and with the injection channel 110 of die body 11.Said screw-in thread 1201 is formed on the inner circumferential surface S1 of said lining 120.
Said injection nozzle 20 comprises showerhead 21 and holder 22.Said showerhead 21 comprises screw thread 210 and antidiarrheal gasket ring 211.Said screw thread 210 is formed on the outer surface of said showerhead 21, and it is meshed with the screw-in thread 1201 of said lining 120, and injection nozzle 20 can be screwed in the lining 120.Said antidiarrheal gasket ring 211 and is fixed on the holder 22 between said screw thread 210 and said holder 22, and the pore size of antidiarrheal gasket ring 211 sizes and said lining 120 is suitable.The degree of depth of the length of said showerhead 21 and said lining 121 is suitable, and when making injection nozzle 20 be screwed in the lining 120, showerhead 21 stretches in the inlet 1200 of lining 120, and said antidiarrheal gasket ring 211 blocks said lining 120 openings.
When in mould, injecting the mould material; Utilize the screw thread 210 of injection nozzle 20 and the screw-in thread 1201 of lining 120 that injection nozzle 20 is threaded in the lining 120; Said antidiarrheal gasket ring 211 blocks said lining 120 openings, utilizes injection nozzle 20 will inject the mould material at last and is injected into mould 10 through inlet 1200 and injection channel 110.
Said device for injection moulding utilizes the screw thread of injection nozzle to be meshed with the screw-in thread of bush inside, and injection nozzle is screwed in the lining, utilizes the antidiarrheal gasket ring to block the lining opening at last, carries out ejection formation then.Can prevent to inject the problem that the mould material oozes out from inlet thus.
Those skilled in the art will be appreciated that; Above embodiment only is to be used for explaining the present invention; And be not to be used as qualification of the present invention; As long as within connotation scope of the present invention, the appropriate change that above embodiment is done all drops within the scope that the present invention requires to protect with changing.
