Plastic thermal molding machine

Abstract

The invention discloses a modified invention of a plastic thermal molding machine. The plastic thermal molding machine comprises a material rack, a conveying device, a heating device, a molding device, a blanking device, and a stacking device. The plastic thermal molding machine is characterized in that the molding machine comprises a molding mould, a fixed mould plate, a moving mould plate, and a power source. The fixed mould plate is provided with guide pillars. The moving mould plate is matched with the guide pillars through guide sleeves. The molding mould is installed on the moving mould plate. The moving mould plate is connected with the power source through an arm of force. The arm of the force is connected with the moving mould plate and the power source through a spindle. A roller pin is installed between the spindle and the shaft joint of the arm of the force. The molding device and the blanking device of the plastic thermal molding machine utilize the power source to drive the mould. Pressure of the power source is big and clamping force of the power source is strong. Products are good in molding effect and good in quality. Abrasion of the spindle to the roller pin is small. Service life is long. Production cost can be reduced.

Description

technical field [0001] The invention relates to an improved invention of a plastic thermoforming machine. Background technique [0002] The plastic thermoforming machine is mainly composed of a heating part, a forming part and a punching part. The punching part of the existing plastic thermoforming machine is completed by another equipment using manual feeding, so the labor intensity of the workers is high, and the hidden danger of accidents is high. The production cost is relatively high; the upper and lower molds of the forming part and the punching part are connected to the power source through the force arm, and the mold and the force arm, and the force arm and the power source are all hinged, that is, connected through the rotating shaft. In order to avoid the direct impact of the rotating shaft If the shaft is damaged, a shaft sleeve is set on the rotating shaft. After long-term use, the shaft sleeve will be worn, and the worn parts are concentrated, easily damaged, an...

[0002] The plastic thermoforming machine is mainly composed of a heating part, a forming part and a punching part. The punching part of the existing plastic thermoforming machine is completed by another equipment using manual feeding, so the labor intensity of the workers is high, and the hidden danger of accidents is high. The production cost is relatively high; the upper and lower molds of the forming part and the punching part are connected to the power source through the force arm, and the mold and the force arm, and the force arm and the power source are all hinged, that is, connected through the rotating shaft. In order to avoid the direct impact of the rotating shaft If the shaft is damaged, a shaft sleeve is set on the rotating shaft. After long-term use, the shaft sleeve will be worn, and the worn parts are concentrated, easily damaged, and need to be replaced frequently. This will not only increase the workload, reduce production efficiency, but also increase production costs; Due to the small force on the hinge, only vacuum molding can be used. The vacuum molding pressure is small, the clamping force is small, and the effect is poor.
