Problems solved by technology

In order to force the shaped rubber tube to leave the mold, it is necessary to continuously pull the rubber tube toward the discharge end. However, since the inner wall of the rubber tube is in contact with the mold core, the friction force on the rubber tube is relatively

Abstract

The invention relates to the field of rubber, and particularly discloses a rubber pipe molding device which comprises a framework, a stepper motor, an extrusion pipe and a core mechanism. A feed pipeis fixed onto the extrusion pipe; the core mechanism comprises an inner rod, a rotary shaft, a liquid inlet pipe, a liquid outlet pipe and a piston, the inner rod can be driven by the stepper motor torotate, an accommodating cavity is arranged in the inner rod, openings are formed in the side walls of the accommodating cavity, elastic sheets are arranged outside the openings and are fixed to theouter wall of the inner rod, first magnets are embedded in the elastic sheets, and second magnets are fixed onto the rotary shaft; the piston is positioned in the accommodating cavity and is in threadfit with the rotary shaft, balls are arranged between the piston and the rotary shaft, a slide groove is formed in the side walls of the accommodating cavity, and a slider is fixed onto the piston; aliquid inlet check valve and a liquid outlet check valve are fixed into the liquid inlet pipe and the liquid outlet pipe, and the liquid inlet pipe and the liquid outlet pipe are communicated with the accommodating cavity. According to the scheme, the rubber pipe molding device has the advantages that tensile force required for pulling rubber pipes can be reduced, and the rubber pipes can be prevented from being dragged to deform.

Description

technical field [0001] The invention relates to the field of rubber, in particular to the field of rubber tube molding. Background technique [0002] The rubber tube is resistant to ultraviolet light, ozone, high and low temperature (-80 to 300 degrees), high transparency, strong resilience, compression resistance, oil resistance, stamping resistance, acid and alkali resistance, wear resistance, flame retardant, voltage resistance, conductivity, etc. Performance, suitable for various harsh working environments, the production of rubber tubes has also been greatly developed. [0003] At present, the commonly used rubber tube molding equipment is an extrusion device, which heats the rubber raw material to a molten state, then uses a special extrusion device to extrude it, and then cools and cuts it. Because the cross-section of the rubber tube is circular, the extrusion device generally includes a cylindrical mold on the periphery and a cylindrical mold core inside the mold. ...
