The main purpose and scope of vulcanizing machine

Main uses and scope of use
This flat vulcanizing machine is a special equipment for pressing various general smaller specifications rubber model products and thermosetting and thermoplastic plastic model products.
Hold for a certain period of time, soften the rubber together, and quickly flow through the mold cavity, reduce or eliminate the flashing and meat shortage of the product, and make the product more dense, which is helpful to eliminate the occurrence of moisture and volatile substances in the blank Bubbles, and then improve the product qualification rate.
4. Components and structural characteristics of each part of the machine
This machine is mainly composed of the host part, hydraulic control part, electrical control part, etc. The column-type down-pressure structure is selected, and the whole machine has a compact structure and beautiful appearance.
(1) The main part includes frame plate, oil cylinder, plunger, working table, sealing structure, guide equipment, upper beam and lock nut, etc. The equipment has high strength, high safety, stable movement of plunger and hot plate, and temperature Evenly.
(2) The hydraulic control part is composed of oil tank, oil supply equipment, conditioning and safety maintenance equipment, pressure-holding mold opening and other parts. The set of controls is stable, safe and reliable, and the large oil supply makes the equipment work efficiency will be extremely high Great progress.
The electrical control unit set of this machine is safe and reliable. Together with the hydraulic unit set, it forms the entire control system of the equipment, which mainly includes motor maintenance equipment, temperature conditioning equipment, timing equipment, alarm equipment and so on.
5. Hydraulic system
Due to the high clamping pressure of the machine, the selected oil cylinder is also large, which requires the hydraulic station to supply a large flow of hydraulic oil when the equipment is closed; in order to complete this intention, the hydraulic system of the machine uses high and low pressure compound In the mold closing process, the large flow low pressure oil supplied by the large flow low pressure pump is mainly used to complete the action. When the pressure is increased after the mold closing, the low pressure unloading overflows, and the small flow high pressure pump supplies high pressure, which ensures both The operating efficiency of the equipment has been reduced, and its driving rate has been reduced, achieving the intention of reducing consumption and increasing efficiency.
In order to reduce the equipment area and improve the utilization rate of the plant, the hydraulic control station selects the patented floating coupling type dual pump, and the vertical installation method with the motor, which makes the structure extremely compact and reduces noise.
When starting, the motor drives the oil pump. The oil pump filters the hydraulic oil through a mesh oil filter on the oil suction line, and outputs pressure oil at the oil outlet. At this time, the high and low pressure oils are maintained by the high and low pressure relief valves. , Flows through the high and low pressure check valve and pressure maintaining check valve, enters the oil cylinder, and pushes the plunger to quickly rise for mold clamping action; after the mold is closed, the system enters the pressure increase state, the oil pressure rises, and the low pressure check valve on the valve plate Closed, the low-pressure pump is maintained by the low-pressure relief valve to do the unloading operation of 0.5Mpa, and the high-pressure relief valve is maintained to maintain the high-pressure pump to supply high-pressure oil to the system alone; when the pressure reaches the specified value, the power supply is automatically cut off, click to stop the operation, The pressure-holding check valve closes quickly and maintains the pressure in the cylinder together with the manual control valve; after the pressure is completed, the manual control valve is opened, then the hydraulic oil in the cylinder flows back to the oil tank through the manual control valve, the mold opening is completed, and a working cycle is completed. During the whole action, the pressure of the system has been indicated by the pressure gauge.
