Description
Technical field
The present invention relates to a kind of overlap crush-cutting instrument of rubber.
Background technology
Overlap overflows into the gap locations such as mould spue line or stripper pin in moulding process and the residue material limit stayed on Injection moulded part.
Also there is overlap in rubber edge in the production process of rubber, and overlap is also low due to the closely sealed precision of the contact surface between punch and die, and doses is too much, and clout leaks at weak seal place and formed.In prior art, rubber overlap processing method is varied, mainly comprises following three kinds: free-hand facture, freezing processing method, cylinder grinding method.Different to the requirement of hardware when these three kinds of methods use, process the effect obtained also not identical, and processing cost there is notable difference.
(1) free-hand facture: workman is free-hand to be separated rubber with inside and outside overlap along certainly tearing mouth (the thinner thickness place between overlap with rubber) open, and by simple cutting implement as flat-nose pliers etc. is wiped out failing to process clean remaining overlap.This method is simple and practical, does not need main equipment to drop into, but this method Disposal quality is undesirable; Secondly, certain requirement is had to the technical merit of workman.If flat-nose pliers is as improper use, rubber can be broken or cut off the part of rubber body, and then cause substandard products.Utilize the method, higher to the requirement of mould, need just can be completed by injection moulding from tearing mouth open because formed, so will ensure reasonably from tearing mouth-shaped open, the mould that just must have.Be shaped by mould burn-in effects once certainly tear mouth open, the mouth of certainly tearing open of injection moulding gained easily makes overlap process unclean when overlap is separated, tear mouth open and remain overlap.
(2) freezing processing method: the one as batch process rubber burrs has effective ways, freezing processing method is widely used, it utilizes liquid nitrogen rubber to be cooled to rapidly subzero tens degree, reach the object of low temperature brittleness, make rubber and inside and outside overlap be in a kind of brittle state; Recycling compressed air by the blowout at a high speed of a kind of tiny plastic cement material for making clothes, on the rubber making it to act on low temperature brittleness and inside and outside overlap.From tearing a mouthful thinner thickness open, easily break after being subject to plastic cement material for making clothes high-speed impact, and then play the object removing overlap.This method is applicable to the overlap work for the treatment of of rubber in enormous quantities, and production efficiency is higher.But, utilize the party to need to drop into good hardware setting, as refrigerator and with refrigerator supporting can the recycling device of recovering liquid nitrogen or special supply station in a large number, therefore processing cost is higher.The object of low temperature brittleness is to make to be in brittle state from tearing the rubber that mouth goes out open, but whole rubber is all in low temperature brittleness state during practical operation, the plastic cement material for making clothes of such high speed blowout also can strike on body while tearing mouth open at shock, and then it is damaged to cause body to produce, and affects the quality of final products.The whole low temperature brittleness of rubber, can cause harmful effect to properties of product, the situation of the especially brittle deflashing of multiple low-temperature.Utilize the method also must ensure to be in specific requirement from the thickness tearing mouth open, if thickness is excessive, then very easily cause the phenomenon that overlap is residual, treatment effect is not good.
(3) cylinder grinding method: are put into cylinder together with the steel ball that rubber and some are differed in size.In the process that drum turning rolls, jogging inside and outside overlap when relying on steel ball to contact with rubber, to reach the object of process overlap.This method equipment needed thereby drops into low, economical and practical, but the effect of process is undesirable, also higher to the requirement of certainly tearing mouth open, certainly tear open mouthful thickness undesirable time, overlap treatment effect is just poor.Because the rigidity of steel ball is far above the rigidity of rubber, after steel ball clashes into rubber in rolling process, damage is greatly produced to the outward appearance of rubber, affect the presentation quality of rubber.
In sum, very easily cause overlap to remain, damage the phenomenon of body by prior art process overlap, overlap treatment effect is not good.
