Description

The mould of pendulum plate pushing out product

Technical field

The present invention relates to injection-moulding plastic and die cast metal moulding, is the mould of pendulum plate pushing out product.

Background technology

Ejecting mechanism, has following several structure at present, and A has by push piece power resources: motor-driven release, product is released and manually released to hydraulic pressure backing-out punch.Motor-driven release is to utilize injector or die casting machine mould opening force as power, by relevant driving parts, makes it reach the effect that ejects goods masterpiece for releasing part.It is to using hydraulic coupling or compressed air to release as power that hydraulic pressure backing-out punch is released, and such ejecting mechanism moves back and forth and realizes pushing out product by hydraulic cylinder or pneumatic cylinder piston.It is to utilize manpower that the release setting on mould is released for manual pushing out product.Though this class mold mechanism is simple in structure, die cost is low, but inefficiency, and labor strength is large, inconvenient operation.And motor-driven release and hydraulic pressure ejecting mechanism, though their automaticities are strong, operating efficiency is high, but mould is complicated, die cost is high, and mould volume is large, must select special-purpose injector or die casting machine to produce simultaneously, another mould is installed, debugs, keeps in repair inconvenient, mould auxiliary component is many, therefore causes die manufacturing cycle long, affects new product release.B has by push piece part movement mode: straight line push piece, oblique push piece, rotation push piece, swing push piece; C is by push piece mechanism form: have that push rod is released, ejector sleeve is released, push pedal is released.Though firmly, pressure is good for the action of several mould pushing-off mechanisms above, but owing to being all to adopt that goods are local to be released, thus goods to release vestige large, affect products appearance quality, even more serious cause to push up pierce product or stuck release part causes mould to scrap.In order to overcome the deficiency of above mold mechanism, I am in conjunction with production line practical experience for many years, and spy provides following a kind of mould to solve the deficiency of above-mentioned mould.

Summary of the invention

The present invention is to provide the mould of pendulum plate pushing out product, as shown in the figure, after mould is opened, when the push pedal (8) of dynamic model part contacts with the push rod of injector, at this moment push rod is exerted pressure to push pedal (8), push pedal (8) drives push piece plate, moving bulb push rod (7) action of push piece strip, and bulb push rod (7) forces pendulum plate (4) to do arc core-pulling action.Pendulum plate (4) be take connecting axle (5) as axle center rotation, and goods are separated from the circular arc core of mould.This mold mechanism is conducive to the product molding with certain radian, and it has simplified mould structure, has saved die steel material, has reduced production cost.The mould of pendulum plate pushing out product, has solved manual pushing out product, inefficiency, and labor strength is large, unhandy problem.Solved motor-driven release and hydraulic pressure ejecting mechanism, mould structure is complicated, and die cost is high, and mould volume is large, must select just fertile problem of special-purpose injector and die casting machine simultaneously.Solved the problem of mould installation, debugging, maintenance inconvenience.Solved the long problem of die manufacturing cycle.While having solved ejector sleeve, push rod release, release vestige large, affect the problem of quality of item.Having solved while ejecting causes top to pierce the problem of product or stuck release part scrap mould.The mould of pendulum plate pushing out product, it is characterized in that: top clamping plate (1) becomes concavo-convex cooperation with slide block (2), the first screw (3) is fastenedly connected with bulb push rod (7), the bulb partial design of bulb push rod (7) becomes helicitic texture that can be movable, pendulum plate (4) is fixed on fixed block (9) with axle (5), core (11) is fastened on moving platen (6) with the second screw (2), pendulum plate (4) becomes glade plane space to coordinate with core (11), guide pillar (13) is slidably matched with the guide pin bushing (14) being arranged on push pedal (8) and ejector pin retaining plate (10).

Accompanying drawing explanation

Below in conjunction with accompanying drawing, the present invention is further described

Shown in figure:

Fig. 1 is mould matched moulds situation sectional side elevation

Sectional side elevation when Fig. 2 is mould release

In figure, numeral number represents respectively:

1---top clamping plate 2---slide block 3---the first screw

4---pendulum plate 5---axle 6---moving platens

7---bulb push rod 8---push pedal 9---fixed heads

10---ejector pin retaining plate 11---core 12---the second screws

13---guide pillar 14---guide pin bushing

The specific embodiment:

It shown in figure, is the mould of pendulum plate pushing out product, Fig. 1 is matched moulds situation, when the pressure of injector or die casting machine is exerted pressure to liquation, mold cavity injects after melt, the ejection system of injector or die casting machine (hereinafter referred to as former) starts action, work as dynamic model, after cover half separates, dynamic model part moves backward with the power of former, when the push pedal (8) of dynamic model part contacts with former push rod, at this moment the push rod of former is exerted pressure to push pedal (8), promote push pedal (8) mobile, push pedal (8) drives ejector pin retaining plate (10) to promote bulb push rod (7) action, bulb push rod (7) forces pendulum plate (4) to do arc core-pulling action.Pendulum plate (4) be take axle (5) as axle center rotation, and goods are departed from away from mold cores (11).Complete after the release of goods, during matched moulds, the baroclinic block of mould is exerted pressure to slide block (2), and slide block (2) forces pendulum plate (4) return to the action of mould inside direction.

Claims (1)

1. put the mould of plate pushing out product, it is characterized in that: top clamping plate (1) becomes concavo-convex cooperation with slide block (2), the first screw (3) is fastenedly connected with bulb push rod (7), the bulb partial design of bulb push rod (7) becomes helicitic texture that can be movable, pendulum plate (4) is fixed on fixed block (9) with axle (5), core (11) is fastened on moving platen (6) with the second screw (2), pendulum plate (4) becomes glade plane space to coordinate with core (11), guide pillar (13) is slidably matched with the guide pin bushing (14) being arranged on push pedal (8) and ejector pin retaining plate (10).
