Working principle of fully automatic rubber soles press moulding machine

1. Mould structure and automated operation
Mold layering design: The mould consists of a bottom mould plate, a middle cover plate and an upper cover plate. The bottom mould plate is used to place the rubber raw material. The middle cover plate and the upper cover plate are closed by a hydraulic system to form a closed cavity.

Manipulator control device: The manipulator is driven by a telescopic cylinder and a clamping cylinder to realize the automatic opening and closing of the middle cover plate of the fully automatic rubber sole press moulding machine and the push-pull operation of the mould, replacing the traditional manual prying steps of the mould, reducing labor intensity and improving efficiency.

2. Hydraulic drive and pressure control
Hydraulic main system: The hydraulic system of the fully automatic rubber sole press moulding machine consists of a main cylinder, a hydraulic motor and an auxiliary cylinder. The main cylinder drives the heating plate to move up and down, applying pressure to close the mould; the hydraulic motor pushes the mould in and out of the heating zone through a gear tooth row.

Pressure regulation: Adjust the hydraulic parameters according to the sole thickness and material characteristics to ensure uniform pressure distribution during vulcanization and avoid product defects caused by underpressure or overpressure.

3. Heating and vulcanization process
Layered heating system: The upper, middle and bottom heating plates are used to efficiently transfer heat to the mold through heat conduction plates (such as copper or aluminum), and the temperature control accuracy can reach ±2°C. The vulcanization temperature is usually set at 150-180°C, and the time is adjusted according to the material formula.
Thermal efficiency optimization: The heating element is directly embedded near the mold to reduce heat loss, saving more than 30% energy compared to traditional platen heating methods.

4. Automated process and multi-station collaboration
Mold transportation: The mold enters and exits the heating zone through the sliding tracks of the front and rear workbenches, and the hydraulic motor drives the polished rod and gear to achieve precise positioning.
Continuous production: The equipment supports multi-mold cycle operation. While one set of molds is heated and vulcanized, the other set can be filled with raw materials and pre-processed to improve production efficiency.
