In recent years, pharmaceutical packaging products have developed rapidly. The demand of plastic packaging container is increasing day by day, and the molding equipment of plastic packaging container is also increasing. It not only refers to the high speed and high pressure stability of the equipment during the molding process, but also requires the container production to achieve high stability in terms of size fluctuation and quality fluctuation. That is to say, the size and geometry of the container produced must be of high precision. Other indicators such as the quality of exterior and interior production efficiency can also be achieved at a higher level. How will the development direction of injection and blowing machinery present in the future?
First, hydraulic control system with high sensitivity, high reproducibility and stability. In the hydraulic system, in order to realize the function of energy conversion, transfer and control, the plunger screw of the precision injection blowing molding machine is driven by the hydraulic motor, and the injection is controlled by the hydraulic system. The injection pressure, injection speed and plasticizing pressure are controlled by a valve installed in the hydraulic system for single procedure control and unified regulation.
Second, it has fine tuning control performance, excellent and reliable operation and easy to use electronic control system. The adjustment of screw speed of injection blower depends on electronic instrument. An electronic indicator consists of a sensor and a display. According to the difference of unidirectional pulse, the screw speed value determined by computer can be accurately displayed on the display.
Three, it can be high-speed and high-pressure injection of the billet, and in the process of blowing the shrinkage of the container can be very small. Another characteristic of the precision injection blow molding machine is the development of injection pressures, high pressures and ultra-high pressures, which aim to reduce the shrinkage after blow molding and increase the density of the container. Due to the high injection pressure, injection speed, compared with the ordinary blow molding machine, its clamping system has good rigidity, good durability, enough die force and blow force, and can resist high pressure, high pressure pressure. High speed injection of molten plastic, mold deformation is small.
Four, it has excellent plasticizer device, can fully plasticize plastic at uniform temperature, and can be accurately measured. When the melt is injected into the billet mold and begins to form into a blow mold, the plunger screw in the inner cylinder of the injection blower rotates, allowing the feeder to transport plastic pellets filled with juice to the front end of the mold. Tighten and heat. Under the action of the plasticizing material, the material is plasticized. When the melt accumulated at the front end of the syringe is equal to the set injection amount, the screw will generate a certain amount of thrust, so that the screw can accurately measure the melt and appear on the display screen, thus ensuring the accuracy of the pre-formed plastic amount.
Five. Design and manufacture of precision injection billet film and blow mould. The design and manufacture of fine blank mold and blow mold is the premise of obtaining precision container. Therefore, in the design of billet blow mold, the shrinkage rate of plastic raw materials and the factors affecting the accuracy of the container in the mold structure design should be considered, and these factors should be minimized as far as possible. These factors generally include the shrinkage rate of the raw material, the distribution of the shrinkage rate, the location of the injection billet and injection flow, the distribution of the temperature control pipe of the billet mold and the cold water pipe of the blow mold, and the selection of the mold material.
