As a further improvement of the utility model, the number of the chewing tips is 2-10.
As a further improvement of the utility model, the tip is made of beryllium copper.
The utility model discloses an advance gluey system of moulding plastics, it includes injection mold and as above arbitrary one the side advance to glue hot chewing, injection mold includes a plurality of product die cavity, and every product die cavity all is located adjacent two and chews between the point, the product die cavity includes the notes runner of two relative settings, the side advances to glue hot chewing adjacent play of chewing the point and glues the mouth and face to annotating the runner. Wherein, two relative injection gates that set up are located the both sides of product, carry out the symmetry respectively from both sides and advance to glue, and the pressurized is even, does not have the problem that the unilateral was exerted pressure, has significantly reduced the defect of moulding plastics of plastic products.
As a further improvement of the utility model, the injection gates are positioned at two sides of the big end part of the product cavity.
Compared with the prior art, the beneficial effects of the utility model are that:
the technical scheme of the utility model, adopt two side symmetric positions to advance gluey structure, can not produce off-centre in theory, improved eccentric problem by a wide margin, also reduced product defect problems such as shrink or drape over one's shoulders cutting edge of a knife or a sword, improved the product percent of pass. Due to the improvement of the eccentricity problem, the abrasion of the collision part of the die cavity can be greatly reduced, the service life of the die is greatly prolonged, and the use and maintenance cost of the die is reduced. The glue inlet hot nozzle has a simple and practical structure, and has a great help effect on the injection molding production of complex plastic parts.
