Self-flow injection method and self-flow injection molding barrel thereof

Abstract

The invention discloses a self-flow injection method and a self-flow injection molding barrel thereof. A transition diversion tube with a guide tube nozzle is connected to a barrel body or a barrel cover, a sealing element is arranged in the transition diversion tube, a liquid outlet is formed at the transition diversion tube after the sealing element is opened, a breathable blind hole is formed in a position which is opposite to the transition diversion tube, and when oil is injected, the horizontal injection molding barrel is rotated, so that the liquid outlet is controllably switched between a liquid-free cavity and a liquid cavity in the barrel, and a valve device of an existing self-flow valve controlled injection molding barrel is replaced. Thus, the number of parts is reduced, the structure is simple, the assembly is simple and convenient, the manufacturing process is simple, and closing and filling of an automatic line can be implemented, so that the purpose of reducing the cost of unit products is achieved, the auxiliary filling technique is preferably popularized and applied, and the problems of manpower consumption, effort consumption, time consumption, serious waste, environmental pollution and the like because a large quantity of traditional injection molding barrels are used at present are solved.

Description

technical field [0001] The invention belongs to the field of barrel packaging, and in particular relates to a self-flow filling method and a self-flow injection molding barrel. Background technique [0002] In the field of barrel packaging, injection-molded barrels used to pack 10-20 liters of lubricating oil or antifreeze are generally called injection-molded barrels. The valve-controlled filling method and its self-flowing valve-controlled injection barrel mainly solve many shortcomings of traditional injection barrels when filling oil. The technical solution is to symmetrically set liquid outlet holes and The air intake hole of the waterproof and breathable membrane uses a valve and a flexible conduit to assist in diversion. The filling steps are: 1. Connect the valve and the flexible conduit to the liquid outlet; 2. Close the valve; 3. Place the injection barrel horizontally so that the liquid outlet faces Next; 4. Insert the soft conduit into the filling port; 5. Open ...

AI Technical Summary

Problems solved by technology

[0013] The purpose of the present invention is to overcome the shortcomings of the existing injection molding barrels, and provide a self-flow filling method and the self-flow injection molding barrels, which reduce the number of parts, simple structure, easy assembly, less manufacturing processes, and can implement automatic line-closing lid filling. In order to achieve the purpose of reducing the cost of unit products, it is conducive to the promotion and application of this auxiliary filling technology, and solves the current situation of laborious, laborious, time-consuming, serious waste, and environmental pollution caused by the extensive use of traditional injection molding barrels.
