Automatic production equipment for hot water bag and method for producing hot water bag

Abstract

The invention discloses automatic production equipment for a hot water bag and a method for producing the hot water bag. Guide pillars are vertically arranged at the four corners of an engine base of the equipment, and upper support frames are fixedly arranged at the upper ends of the guide pillars. A close mould oil cylinder is arranged at the center of the engine base, and a main sliding block is arranged at the upper end of a piston rod of the close mould oil cylinder. Two sets of translation guide rails and two sets of upper moulds and lower moulds are arranged between the upper support frames and the main sliding blocks. Mould cores are respectively arranged on the upper sides of the lower moulds, and each mould core comprises a core body and a frame. A mould head is arranged on one side of the frame, a threaded core rod is arranged between the mould head and the core body, and the two ends of the threaded core rod are respectively inserted into the mould head and the core body. After is mould closed, each core body is positioned between the corresponding upper mould and lower mould and form a thin-wall empty chamber in a shape like the hot water bag. Translation driving mechanisms are arranged on the lower sides of a first lower mould base and a second lower mould base. The method adopts compression moulding forming and blowing demoulding for automatic production. The equipment and the method are specially used for automatic production of the hot water bag and have the advantages of convenience in demoulding, high rate of finished products and long service life.

Description

technical field [0001] The invention relates to a rubber product production device and a production method thereof, in particular to a hot water bag production equipment and a hot water bag production method. Background technique [0002] In the Chinese patent database, there are: one-time molding inflatable molds and methods for processing hot water bottles using them. The application number of this application: 201510717934.1; application date: 2015-10-29; publication number: CN105196519A; publication date: 2015-12- 30. The mold includes an upper mold shell, a lower mold shell, a die head and an integrated mold core matched with the upper mold shell and the lower mold shell; the bottom of the upper mold shell and the lower mold shell are each provided with a hot water bottle Groove, the grooves of the upper mold shell and the lower mold shell together form a hot water bag-shaped through hole; the integrated mold core includes a mold core body and a frame structure, and the...

Problems solved by technology

Its disadvantages are: despite such a mold design, the equipment used for the mold has not been disclosed; in addition, the hot water bottle is molded on the mold core, and due to the good elasticity of the rubber material, it is difficult to remove the film and the production efficiency is low. Not enough automation
