Abstract
The utility model relates to an automobile storage box mold with an exhaust structure, belonging to the technical field of exhaust structures of molds. The exhaust structure of the mold comprises an exhaust combination block, a blowing device, an air tap and an exhaust passage, and the exhaust structure outside a cavity can cause a temporary vacuum state of an exhaust passage opening during blowing, so that air in the cavity can be pumped out of the cavity due to the difference of pressure of injecting raw materials in the cavity and outside pressure, and the high-efficiency exhausting effect can be achieved. The mold enables air in the cavity to be automatically discharged out of the cavity when a plastic part is subjected to injection molding, thereby reducing the molding pressure in the cavity, reducing the molding time, saving the cost, and improving the working efficiency. According to the mold, the percent of defective products caused by burning is lowered, the waste is reduced, high-efficiency plastic part molding is achieved, and the passing percent of molded products is enhanced.
Description
Technical field
The utility model relates to a kind of automobile storage box mould with exhaust structure, belongs to the exhaust structure technical field of mould.
Background technology
In existing injection moulding die casting mouth design, pressure when exhaust structure generally relies on plastic raw materials to inject die cavity is extruded intracavity gas from die gap, its exhaust velocity is slower and passive, thereby and also increases bad risk because of the not good goods burn that causes of exhaust effect possibly after product molding.
Summary of the invention
In order to solve problems of the prior art, the utility model provides a kind of automobile storage box mould with exhaust structure, and the exhaust dynamics when improving plastic parts moulding increases plastic parts moulding qualification rate.
The technical solution adopted in the utility model is: a kind of automobile storage box mould with exhaust structure, it comprises straight jacking block and the straight push rod being connected with straight jacking block by fixing pin, it also comprises an exhaust structure, described exhaust structure adopts an air exhaust combination piece and a blowning installation, air exhaust combination piece is fixed on straight jacking block by connecting pin, be provided with a valve at the top of blowning installation, between the air exhaust combination piece on described straight jacking block and blowning installation, adopt exhaust duct to be connected.
Described straight jacking block is being provided with sealing ring with the outside of straight push rod intersection.
The beneficial effects of the utility model are: this exhaust structure with the automobile storage box mould of exhaust structure adopts an air exhaust combination piece and a blowning installation, air exhaust combination piece is fixed on straight jacking block by connecting pin, be provided with a valve at the top of blowning installation, between the air exhaust combination piece on straight jacking block and blowning installation, adopt exhaust duct to be connected.Exhaust structure outside die cavity causes the of short duration vacuum state in exhaust road junction place in air blowing process, makes to be drawn out of in chamber under pressure in the time that plastic raw materials injects die cavity of gas in die cavity and outside pressure differential effect, thereby realizes exhaust high efficiency.When this mould can be realized plastic injection moulding, by outside automatic the gas in die cavity discharge side, reduce briquetting pressure in chamber and reduce molding time simultaneously, cost-saving, increase work efficiency.Reduce the goods that cause because of burn bad simultaneously, reduce waste, make goods reach the requirement of customer satisfaction.
Brief description of the drawings
Fig. 1 is the gas flow schematic diagram of a kind of automobile storage box mould with exhaust structure in the time of moulding.
In figure: 1, straight jacking block, 2, air exhaust combination piece, 3, connect pin, 4, fixing pin, 5, straight push rod, 6, sealing ring, 7, exhaust duct, 8, valve, 9, blowning installation.
Detailed description of the invention
Referring to accompanying drawing, structure of the present utility model is described further.
Fig. 1 shows a kind of structure of the automobile storage box mould with exhaust structure and gas flow signal in the time of moulding.Straight push rod 5 and an exhaust structure that the automobile storage box mould with exhaust structure comprises straight jacking block 1, is connected with straight jacking block 1 by fixing pin 4, exhaust structure adopts an air exhaust combination piece 2 and a blowning installation 9, air exhaust combination piece 2 is fixed on straight jacking block 1 by connecting pin 3, be provided with a valve 8 at the top of blowning installation 9, between the air exhaust combination piece 2 on straight jacking block 1 and blowning installation 9, adopt exhaust duct 7 to be connected.Straight jacking block 1 is being provided with sealing ring 6 with the outside of straight push rod 5 intersections.
While adopting technique scheme to carry out plastic injection process, outside valve 8 from blowning installation 9 is blown downwards along the diagram direction of arrow, cause the inner of short duration vacuum state of blowning installation 9, now the pressure in die cavity can be higher than blowning installation 9, under this pressure-acting, intracavity gas can be extracted out the gap between air exhaust combination piece 2, outside exhaust duct 7 discharge sides.Sealing ring 6 also can stop the gas outside die cavity to enter exhaust duct 7 Inner along the gap at straight push rod 5 places simultaneously, thereby improves exhaust efficiency.
