Abstract
The invention discloses a push rod capable of exhausting. The push rod comprises a push rod head, a tool withdrawal groove, a rod body and a suspension table, wherein the tool withdrawal groove is formed in the lower end of the push rod head; the rod body is arranged below the tool withdrawal groove; the suspension table is arranged at the bottom end of the rod body; an upper exhausting groove is formed in one side of the push rod head; a lateral exhausting groove is formed in the rod body; the lateral exhausting groove and the upper exhausting groove are formed in the same side; the lateral surface of the lateral exhausting groove is levelly connected with the tool withdrawal groove in parallel; a convex shoulder is arranged on the suspension table on the same side of the lateral exhausting groove in the rod body; the other side of the suspension table is level and parallel to the rod body without any convex shoulder. The push rod provided by the invention has the advantages of simple structure and convenience in repairing and assembling, so that the quality of a modeling product can be ensured; meanwhile, the modeling period can be shortened; energy consumed by an injector can be reduced; the production efficiency of injection molding is greatly improved.
Description
Technical field
The present invention relates to a kind ofly in injection is produced, gas in die cavity can be discharged in time can exhaust push rod with what guarantee product quality.
Background technology
Injection mold is the important process equipment during plastic injection is produced.Injection mould belongs to swaging die, in injection mo(u)lding, moisture in plastics is met vaporization at high temperature or because plastic additive is at high temperature decomposed to form gas, and after matched moulds in die cavity residual air itself all can cause accumulating in mold cavity large quantity of air, when plastic melt enters die cavity injection moulding fast, these gas need to be discharged in time, otherwise can burn because the high temperature of the compressed generation of gas causes the local charing of goods; Or due to gas, can not discharge in time injection pressure is increased, cause die cavity softened and on goods, form overlap; In addition, if gas cannot be discharged in time, the resistance that pressure in die cavity and melt advance is strengthened, finally make melt filling speed reduce or occur the defects such as lack of fill, these unfavorable factors can finally have influence on Forming Quality and the injection cycle of goods, as product surface formation current mark, gas line, weld mark, part are not fully filled, even cause the local overlap of goods or local charing to burn.Therefore, gas need be got rid of in time, be guaranteed product quality.
Summary of the invention
For the technical problem of above-mentioned existence, the object of the invention is: proposed a kind ofly in injection is produced, gas in die cavity can be discharged in time can exhaust push rod with what guarantee product quality.
Technical solution of the present invention is achieved in that can exhaust push rod, comprises push rod cup, escape, the body of rod, hanging platform; Described push rod cup lower end is provided with escape; Described escape is arranged with the body of rod; The bottom of the described body of rod is provided with hanging platform; One side of described push rod cup offers air discharge duct; On the described body of rod, offer side air discharge duct, described side air discharge duct and upper air discharge duct homonymy, and the side surface of side air discharge duct is concordant with escape joins.
Preferably, be provided with protrusion shoulder with the hanging platform of the side air discharge duct homonymy on the body of rod, described hanging platform opposite side is mutually concordant with the body of rod, without protruding shoulder.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
Of the present invention can exhaust push rod, simple in structure, repair is convenient, can guarantee the quality of shaped article, can shorten molding cycle simultaneously, reduce the energy resource consumption of injector, greatly improve injection moulding production efficiency, the structure of described hanging platform, can realize the installation of push rod in upper ejector plate, so, can guarantee reliable installation and the easy motion of push rod, can solve again when push rod is more and occur the problem that installing space is interfered.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, technical solution of the present invention is described further:
Accompanying drawing 1 is front view that can exhaust push rod of the present invention;
Accompanying drawing 2 is assembling schematic diagram that can exhaust push rod of the present invention;
Accompanying drawing 3 is the enlarged drawing of the A portion in accompanying drawing 2;
Wherein: 1, push rod cup; 2, escape; 3, the body of rod; 4, hanging platform; 5, upper air discharge duct; 6, side air discharge duct; 7, master mold version; 8, plastic; 9, mother module core; 10, male die core; 11, male model plate; 12, can exhaust push rod; 13, upper ejector plate; 14, gas is discharged direction.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention is described.
As accompanying drawing 1-3 be depicted as of the present invention can exhaust push rod, comprise push rod cup 1, escape 2, the body of rod 3, hanging platform 4; Described push rod cup 1 lower end is provided with escape 2; Described escape 2 is arranged with the body of rod 3; The bottom of the described body of rod 3 is provided with hanging platform 4; One side of described push rod cup 1 offers air discharge duct 5; Describedly on the body of rod 3 of upper air discharge duct 5 homonymies, offer side air discharge duct 6, described side air discharge duct 6 and upper air discharge duct 5 homonymies, and the side surface of side air discharge duct 6 is concordant with escape 2 joins; Be provided with protrusion shoulder with the hanging platform 4 of side air discharge duct 6 homonymies on the body of rod 3, described hanging platform 4 opposite sides are mutually concordant with the body of rod 3, without protruding shoulder.
After push rod cup 1 assembling that can exhaust push rod 12, in male die core 10, the end face of push rod cup 1 is than the high 0.05～0.1mm of male die core 10 end face, with plastic 8 inner surfaces after avoiding moulding because many glue forms boss; Upper air discharge duct and the male die core 10 of described push rod cup 1 form little gap, its gap width is less than the grain density of plastics, prevent that in forming process, glue phenomenon is leaked in generation, the little gap that this place forms will form the initiating terminal of gas extraction system, and the body of rod 3 and the male model plate 11 of the opposite side of described side air discharge duct 6 forms the assembling form of interference fits; One section of side air discharge duct 6 at upper air discharge duct 5 homonymies is tangent with the side surface of escape 2, make gas extraction system form unobstructed gas return path, after assembling, this section is in male die core 10, and the gas in die cavity is by can finally being got rid of outside mould by the space between male model plate 11 and upper ejector plate 13 after the exhausting loop of exhaust push rod.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
Of the present invention can exhaust push rod, simple in structure, repair is convenient, can guarantee the quality of shaped article, can shorten molding cycle simultaneously, reduce the energy resource consumption of injector, greatly improve injection moulding production efficiency, the structure of described hanging platform, can realize the installation of push rod in upper ejector plate, so, can guarantee reliable installation and the easy motion of push rod, can solve again when push rod is more and occur the problem that installing space is interfered.
Above-described embodiment is only explanation technical conceive of the present invention and feature; its object is to allow person skilled in the art can understand content of the present invention and be implemented; can not limit the scope of the invention with this; all equivalences that Spirit Essence is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
