Problems solved by technology

The existing three-color plastic sole molding machine has three sets of plasticizing and injection mechanisms and material blocking cylinder components at different positions around the turntable mechanism. Four operators are required in the production process. It has brought a lot of pressure to the enterprise; in addition, the heating devices in the existing plasticizing and injection mechanisms all use resistance wires as heating elements to heat the raw materials in the barrel by conduction, resulting in low thermal efficiency

Abstract

The invention relates to a three-color plastic sole molding machine, comprising a clamping mechanism, a rotary mechanism, plasticizing and injection mechanisms, a hydraulic system and a control system. A primary injection device and an auxiliary injection device are provided, wherein the auxiliary injection device is provided with two groups of plasticizing and injection mechanisms, so that only two stations require workers to finish the injection molding of a three-color color product, thereby reducing operating workers; at the same time, the heating device consists of an electromagnetic spiral coil winding on a coil frame, high frequency alternating current power supply is applied on the spiral coil to induce eddy current on an iron injection screw for heating, and the raw materials are directly heated from the inside of a material canister, so as to achieve rapid heating and higher heating efficiency.

Description

technical field [0001] The invention relates to a molding machine for plastic soles, in particular to a molding machine for three-color plastic soles. Background technique [0002] Plastic sole molding machines usually include mold clamping mechanism, turntable mechanism, plasticizing and injection mechanism, hydraulic system and control system. There is a barrel in the plasticizing and injection mechanism, a heating device is installed on the barrel, an injection screw is installed in the barrel, an injection head is arranged at the front end of the barrel, an injection hole is arranged in the injection head, and a blocking material is connected in front of the injection head. A cylinder assembly, a motor and an injection mechanism for driving the injection screw are provided at the rear end of the barrel. The existing three-color plastic sole molding machine has three sets of plasticizing and injection mechanisms and material blocking cylinder components at different posi...
