Cangbao Pipe Molding Machine, national registered trademark
Pipe molding machine includes motor, oil pump, electromagnetic reversing valve, mold base, and case. Oil pump is arranged within the machine case. Heat dissipation, noise reduction, high efficiency, energy effectiveness, and other design objectives are achieved through immersing the oil pump below oil level. Driven by the motor, the oil pump exports hydraulic oil, toelectromagnetic reversing valve, and in this period, the valve opened in forward direction, so oil goes through and pushes the plunger inside cylinder to move forward, enabling the shrinking of mold base inner diameter, so molds are closed and pressed on the pipe sleeve. When the preset fine adjustment valve is reached, the closing and molding will seize automatically. And at this time, the electromagnetic opens in backing direction, and oil pushes the plunger to move backward, so the molds are opened, and rubber pipe pressing ends.
