Large-scale forming mechanism for EVA rubber shoes

Abstract

The invention discloses a large-scale forming mechanism for EVA rubber shoes. The large-scale forming mechanism for the EVA rubber shoes is provided with a linear electric cylinder so that a lower mold and an upper mold can be located on the same straight line, plastic is put into a feeding mechanism, the molten plastic flows out of a filtering hole, passes through a discharging pipe and then flows into a material pressing pipe, a second air cylinder is driven, the liquid plastic is downwards extruded until the liquid plastic flows out of a flow pipe to flow into an upper mold cavity in the upper mold, then a first air cylinder is driven, the upper mold and the lower mold are attached, after cooling, the first air cylinder is driven, the linear electric cylinder is driven while the upper mold moves upwards, the next lower mold is moved to the position right below the upper mold, in the manufacturing process, large-scale production is realized, the automation is basically realized, and the working efficiency is improved; and meanwhile, a second piston rod provided by the large-scale forming mechanism moves downwards to downwards extrude the liquid plastic until the liquid plastic flows out of the flow pipe to flow into the upper mold cavity in the upper mold, the extruded plastic liquid is more compact, the mold is firmer, and the formed plastic shoes are more wear-resistant.

Description

technical field [0001] The invention relates to the field of molding EVA rubber shoes, in particular to a large-scale molding mechanism for EVA rubber shoes. Background technique [0002] In the field of chemistry and organic chemical industry, EVA refers to "ethylene-vinyl acetate copolymer" and its rubber and plastic foam materials, which can be used to make plastic shoes. Plastic is a molten liquid during the manufacturing process, so it can be heated to melt, pressurized to flow, cooled to solidify, and formed into various shapes. [0003] In the prior art, the production of rubber shoes is generally processed by mechanical equipment, heated by manual feeding, and then injection molded. After one mold is completed, the next mold is injection molded. It is impossible to form a large-scale production system. Also wasted time during operation, reduced efficiency. At the same time, EVA rubber shoes are not tight enough between the plastic and the plastic after molding in t...

Problems solved by technology

[0003] In the prior art, the production of rubber shoes is generally processed by mechanical equipment, heated by manual feeding, and then injection molded. After one mold is completed, the next mold is injection molded. It is impossible to form a large-scale production system. It also wastes time during operation and reduces efficiency

At the same time, EVA rubber shoes are not tight enough between the plastic and the plastic after being formed in the natural state during production, the mold is not strong enough, and its wear resistance cannot be guaranteed.
