The large plastic storage cylinder blow molding machine extruder squeezes the molten material into the storage tank. When the material level of the storage tank rises to a certain height, the displacement sensor 2 sends a detection signal, and after the control part receives the signal, press the advance The adjusted program outputs an analog signal composed of a plurality of voltage values, and the proportional amplifier drives the proportional valve to move, and the gap of the die-core (the wall thickness of the parison) is adjusted by controlling the movement of the cylinder.

Small extruders usually use manual direct feeding; large extruders or multiple extruders are produced side by side. The feeding method of the hopper can be carried out by spring feeding, vacuum feeding and compressed air pipeline feeding.

Plastic Hollow blow molding machines keep the head of the parison clean and are an important prerequisite for extrusion blow molding of high performance products.

The opening and closing mode of the plastic extrusion blow molding machine of the blow molding machine is an important process in the plasticization, injection, pressure keeping and cooling, product molding and product demoulding of the injection machine. With the opening and closing mode action of the mold clamping device, the mold can form a cavity of the injection molded product, thereby ensuring that the mold cavity is not expanded by the pressure of the injection melt, thereby ensuring the quality of the injection molded product. It can be seen that the firm reliability of the combination of the forming mold, the movement flexibility of the mold opening and the convenient and safe removal of the finished part are all ensured by the accurate and reliable action of the mold clamping device.

Kingplas - Chinese Plastic Blow Molding Machine Manufacturer There are many heating methods for the hollow blow molding machine barrel, and the resistance heating method and the electric induction heating method are used more. Cast aluminum sleeve heaters are the most widely used in resistance heating.

Extrusion stretch blow molding machine biaxial stretch orientation blow molding technology is developed on the basis of ordinary extrusion hollow blow molding machine. The containers produced by the extrusion blown process have a certain degree of orientation of the axial and radial macromolecules, so they show excellent performance and develop rapidly.

Hollow plastic blow molding machine hydraulic servo system is a hydraulic system with high precision technical requirements. It mainly consists of electro-hydraulic servo valve, relief valve, check valve, inlet and return filter, accumulator, hydraulic manifold, high pressure hydraulic Pump and motor, oil cooler, fuel tank and other components.

The opening and closing action of the mold clamping device of the China extrusion hollow plastic blow molding machine is an important process in the injection molding machine's plasticization, injection, pressure holding and temperature reduction, product molding and product demoulding. With the opening and closing action of the mold clamping device, the mold can form a cavity of the injection molded product, thereby ensuring that the mold cavity is not expanded by the pressure of the injection melt, which also ensures the quality of the injection molded product. It can be seen that the firm and reliable combination of the forming mold, the flexibility of the combination of the mold opening, and the convenience and safety of taking out the finished product from the mold are all guaranteed by the accurate and reliable movement in the mold clamping device.

There are many heating methods for the hollow cylinder of the blow molding machine, and the resistance heating method and electric induction heating method are more commonly used. In resistance heating, cast aluminum jacket heaters are most commonly used.

The manufacturing price of large blow molds and tools is relatively high, accounting for a large proportion of fixed asset investment. The blow mold factory has good economic benefits for mold maintenance and maintenance, and it is also an important guarantee for the stability and improvement of the quality of blow mold products.

Hollow blow molding electro-hydraulic proportional valves use proportional electromagnets (torque motors, force motors, servo motors, etc.) that have a driving force proportional to the input current to replace the manual given device, and are connected with the basic parts of the valve (with ordinary hydraulic control The valves are basically the same).

Hollow blow molding machine hydraulic servo system is a hydraulic system with high-precision technical requirements, mainly composed of electro-hydraulic servo valves, relief valves, check valves, inlet and return filters, accumulators, hydraulic manifolds, high-pressure hydraulics Pump and motor, oil cooler, fuel tank and other components.
