Problems solved by technology

The advantage of this device is its simple structure. The disadvantage is that the injection pressure must be high enough to overcome the force of the spring to open the nozzle. High pressure will further heat the raw material, resulting in chemical changes such as degradation. This device is especially not suitable for silica gel, which requires low temperature. Raw material for injection molding
The other is to use external force to drive the needle valve, which requires a relatively complex mechanical structure, which is expensive and expensive to maintain

Abstract

The invention discloses a multicolor vertical injection molding machine for a center rotating tower and an injection molding method. The injection molding machine comprises a rack, a lower die plate,an upper die plate, a die locking plate, guide pillars, the center rotating tower, a material injection device and a center rotating tower stripping device. The center rotating tower is internally provided with positioning grooves used for positioning insert seats so that the insert seats can be installed conveniently. A hopper basket in the material injection device is provided with heating plates which are intersected longitudinally and transversely so that materials can be evenly heated. The material injection effect can be better by controlling the temperature of a material cylinder. The material cylinder is provided with a material nozzle. A needle valve and pneumatic control are adopted so that material control can be more reliable. Reliable stripping of finished products can be achieved through the stripping device. By means of the injection molding method, die locking is adopted for achieving die opening and die assembling; the center rotating tower is used for achieving multicolor material injection forming; and the center rotating tower stripping device is used for achieving stripping.

Description

technical field [0001] The invention relates to a vertical injection molding machine. Background technique [0002] Injection molding machines generally include vertical injection molding machines and horizontal injection molding machines. Injection molding machines are usually composed of injection system, mold clamping system, hydraulic transmission system, electrical control system, lubrication system, heating and cooling system, safety monitoring system, etc. The injection system is one of the most important components of the injection molding machine. Generally, there are three main forms: plunger type, screw type, and screw pre-molded plunger injection type; currently the most widely used is the screw type, which is used in injection molding machines. In the injection molding process, after a certain amount of plastic is heated and plasticized within a specified time, the molten plastic is injected into the mold cavity through a screw under a certain pressure and spee...
