Description
Technical field
The present invention relates to a kind of mechanism of rubber machine；Specifically a kind of Zhuan She mechanisms applied to rubber injection moulding machine.
Background technology
In rubber machine, injection device is typically all that viscous state rubber raw materials, which pass through, to be turned to penetrate on plate directly in turning to penetrate on plate
Hole enter lower section mould in；Injection device penetrates plate in pressure injection using contacting firmly with turning, and is easily damaged.
In addition, turning to penetrate plate suqare big, lower section needs to design runner, but area is big so that the pressure point of injection device conduction
Dissipate, pressure is reduced, and the viscous state rubber raw materials in runner do not press tightly reality, material head increase.
The content of the invention
The present invention is in view of the shortcomings of the prior art, provide using soft contact, and the one kind that can reduce material head is applied to rubber
The Zhuan She mechanisms of glue injection (mo(u)lding) machine.
In order to solve the above-mentioned technical problem, the present invention is addressed by following technical proposals：One kind is applied to rubber and noted
Penetrating the Zhuan She mechanisms of forming machine includes injection device and turns to penetrate plate, and the injection device is set down, including injection rod, oversheath
And it is arranged on the nozzle of front end；To penetrate on plate to be provided with for described turn and turn perforation, the chambering at two ends for turning perforation forms step edge,
Counter flange and nut are separately installed with, the cylindrical portion insertion of the counter flange turns in perforation, and method is provided with cylindrical portion
Blue stepped hole, against the upper surface of counter flange, the nozzle is inserted in the flange stepped hole injection rod；Turn to penetrate head
Upper surface be concave spherical surface, the lower end of the nozzle is convex spherical, and the convex spherical is engaged with the concave spherical surface.
The flange stepped hole is provided with first step and second step, is provided with the first step and turns to penetrate head, institute
State and spring is provided with second step, penetrate for described turn and injection orifice is set in head, the described turn of upper surface for penetrating head can contradict nozzle, institute
State the lower surface for turning to penetrate head and contradict the spring；The upper surface for turning to penetrate head is concave spherical surface, and the lower end of the nozzle is convex spherical,
The convex spherical is engaged with the concave spherical surface.
The nut and turn to penetrate between plate flexible pad is set.
The present invention compared with prior art, has the advantages that：1. in work, the lower pressure of injection rod is a part of
It is conducted to by nut and turns to penetrate plate, some is conducted to the rubber in runner by counter flange, majority is undertaken by counter flange
Lower pressure, rather than all undertake lower pressure by turning to penetrate plate in original structure；Lower pressure to turn to penetrate plate and counter flange
Form the sunk area of a distance element, lowermost end of the counter flange positioned at depression；Because counter flange undertakes the lower pressure of majority,
It is more than its downward displacement to turn to penetrate plate, such that the pressure in the stress area below counter flange is bigger, from
And caused expansive force during rubber vulcanization is more effectively resisted, also cause more consolidation between counter flange and mould, produced
The waste materials such as raw overlap are less, wasted so as to reduce；Turn to penetrate head and spring 2. being provided with, first, nozzle can be avoided to penetrate plate with turning
Direct hard contact, change and form soft contact, nozzle can be reduced and turn to penetrate the cementation zone damage of plate；Second, spring
Elastic force can guarantee that nozzle and turn to penetrate the seamless cooperation between head in injection process with lifting preliminary stage, can prevent nozzle from noting
Sprayed outside the rubber of liquid matter state during penetrating, can prevent that nozzle is excessive in the rubber not cooled down completely of lifting preliminary stage；
Third, the resilience for turning to penetrate head additionally aids automatic cutting, the rubber material head between injection port and mould is cut off, and in first step
Rubber material head, facilitate and follow-up take waste material and take overlap；3rd, nut and turn to penetrate between plate flexible pad is set；First, energy
Reduce the plate that turns to penetrate positioned at two steps between and produce fatigue of materials；Second, counter flange is set to cancel in the lower pressure of injection rod
Afterwards, resilience crest is higher, and fracture effect is more preferable.

Embodiment
The present invention is described in further detail with embodiment below in conjunction with the accompanying drawings：As shown in figs. 1-7, mark such as
Under：Injection device 1, injection rod 11, oversheath 12, nozzle 13, convex spherical 14, turn to penetrate plate 2, turn perforation 21, step along 22, transition
Flange 3, flange stepped hole 31, first step 32, second step 33, nut 4, turn penetrate first 5, injection orifice 51, concave spherical surface 52, spring
6th, pad 7, runner 8, mould 9.
A kind of Zhuan She mechanisms applied to rubber injection moulding machine include injection device 1 and turn to penetrate plate 2, and injection device is down
Set, including injection rod 11, oversheath 12 and the nozzle 13 for being arranged on front end；Turn to penetrate on plate to be provided with to turn perforation 21, turn to penetrate
The chambering at two ends in hole forms step along 22, is separately installed with counter flange 3 and nut 4, the cylindrical portion insertion of counter flange turns to penetrate
Flange stepped hole 31 is provided with hole, and in cylindrical portion, for injection rod against the upper surface of counter flange, nozzle is inserted in flange platform
In rank hole；Flange stepped hole is provided with first step 32 and second step 33, is provided with first step and turns to penetrate first 5, second
Spring 6 is provided with rank, turns to penetrate setting injection orifice 51 in head, nozzle can be contradicted by turning to penetrate the upper surface of head, turn to penetrate the lower surface of head
Contradict spring.
Under the driving of pressure, the viscous state rubber raw materials in injection rod and nozzle chambers, pass through the note for turning to penetrate in head
Perforation enters in air stream enter runner, final to inject in die cavity, waits pressurize and condensation；Deng pressurize and after condensation a period of time, viscous state rubber
Glue becomes solid rubber；When injection device moves down, counter flange also can stress to bottom offset, so as to extrude runner so that only use
Reduced to fill the rubber consumption of runner；Injection device pressure upstream is disappeared, and spring, which forces, to be turned to penetrate the upward resilience of head, so as to cut off
The broken end of solid rubber in die cavity.
Turn to penetrate the upper surface of head and the lower end of nozzle is engaged, the upper surface for preferably turning to penetrate head is concave spherical surface 52, nozzle
Lower end be convex spherical 14, the pattern that convex spherical is engaged with concave spherical surface, tapered cooperation can also be used.
Counter flange raised can typically turn to penetrate the lower surface several to tens of plate, depending on rubber model, injection
Pressure, the size of runner 8, the position of mould 9 etc. are different.
In nut and it can also turn to penetrate between plate flexible pad 7 is set, elastic pad can be metallic cover pad
Piece, graphite flake, sheet asbestos, basin pad etc. have high temperature resistant and have the pad of a small amount of rebound performance, it is only necessary to increase several and tens
The fluctuation of silk, it is possible to so that cut-out effect is more preferable, play a part of Double spring so that counter flange Bottom Runby and resilience
The effect of distance increase, the rubber effect being compacted in runner and cut-out rubber column cap is more preferable.
