The structure of the injection molding machine, injection molding machine according to the way of plasticizing divided into plunger type injection molding machine and screw injection molding machine; According to the machine can be divided into the hydraulic drive and mechanical and hydraulic & ndash; Machinery ( Connecting rod) Type; According to the operation mode is divided into automatic, semi-automatic, manual injection molding machine. What are the classification of the plastic injection molding machine? ( 1) Horizontal injection molding machine: this is the most common type. The clamping part and injection part center online at the same level, and the mould is opened along the horizontal direction. Its characteristic is: the fuselage short, easy to operation and maintenance; Low center of gravity, installation is relatively stable; Products out after use gravity fall automatically, easy to realize automatic operation. At present, the injection molding machine on the market use this kind of type more. ( 2) Vertical injection molding machine, the clamping part and injection part in the same vertical center line, and the mould is opened along the vertical direction. As a result, it covers an area of small, easy to put insert, it's convenient to make loading and unloading of the mould, the materials from the hopper into the plasticizing more evenly. But not easy to automatically after products out, must be removed by hand, not easy to realize automatic operation. Vertical injection made for small injection molding machine, general is to use more below 60 grams of injection molding machine, large and medium-sized machine should not be used. ( 3) Angle of injection molding: direction and its injection mold interface in the same plane, it is especially suitable for machining center parts are not allowed to leave the gate marks the plane of the products. It covers an area smaller than horizontal injection molding machine, but fell into the mould insert is easy to tilt. This type of injection made for small machine. ( 4) Multimode disc injection molding machine: it is a kind of more special injection molding machine location operation, its characteristic is clamping device used the rotating disc structure, mould around the axis of rotation. This type of injection molding machine give full play to the plasticizing capacity of injection device, can shorten the production cycle, improve the machine's production capacity, and therefore particularly suitable for cooling to finalize the design or due to put long insert and need more auxiliary time of mass production of plastic products, but because of the large, complex mold clamping system, mould clamping force of clamping device is often small, in the production of plastic products such as sole in the injection molding machine. Injection molding is a process of circulation, each cycle mainly includes: quantitative loading & ndash; The molten plasticizing & ndash; Injection pressure & ndash; Molding cooling & ndash; Rev pick-up. After take out the plastic mold closing again, for the next cycle.
