Core two-color toothbrush injection molding machine, production can be without re-opening the mold, the original mold of the core two-color toothbrush can be. The injection molding machine is equipped with twin screw barrel and specially designed compound nozzle, which realizes the innovative injection molding processing technology of the two-color toothbrushes with the core and achieves the goal of beautiful appearance. In the injection process, the two raw materials are respectively shot into the mold hole to achieve the sandwich injection effect, wherein the outer layer of the melt is called the skin transparent material, and the inner layer of the melt is called the core color material. The core color material and the skin transparent material produce beautiful appearance. Core two-color toothbrush injection molding machine features: high speed, high precision, high repeatability mold locking part 1 High precision and high rigidity template, to achieve the requirements of precision injection molding. 2 The five-point hyperbolic vertical arm clamping mechanism and hard chrome-plated high tension Golin column make the clamping action stable and durable. 3 Lengthening die stroke and large modulus suitable for installation of various molds. 4 Non-regressive, vibration or multiple oil pressure ejection function. 6 Fast opening and locking, low pressure mold protection and high pressure mold locking between the variable segment sensitive and accurate, so that the opening and closing mold action is both rapid and stable. Injection part 1 nitriding screw and melt cartridge. 2 High speed and high pressure injection and melting properties can improve production. 3 Automatic cleaning of melt tube and automatic shift table. 4 screw back pressure control. The control system can input pressure, speed, position, time and melt tube temperature data directly from the computer. 1 Setting of injection pressure, speed and screw position. 2 Set pressure, speed and time. 3 Use high-precision electronic ruler to accurately measure the position of template, screw and thimble. 4 injection glue amount detection function and screw anti-cold start. 5 Mixed two-color injection molding machine parameters and mold data can be stored in the computer or through an external SD memory card. 6 Multi-layer password protection to prevent data from being easily changed the hydraulic control part 1 Equipped with high-horsepower electric motor to drive high-displacement oil pump for high-speed and high-pressure performance. 2 Efficient precision oil circuit design and with imported brand control valves and accessories, to provide precision injection molding conditions. 3 The oil pressure control is placed close to its control mechanism to reduce the reaction error caused by oil circuit detour.

After receiving the electronic signal through D5, the pressure oil enters the preplasticized tube cavity through V3, and the oil discharged from the preplasticized tube is directly returned to the oil T, so that the preplasticized tube rotates to complete the preplasticized action. The oil in the rodless chamber of the injection cylinder reaches the return oil T through V2, and then reaches the return oil T through V4. Adjusting V4 can achieve the adjustment of screw backward speed. Clamping control module This module is mainly for clamping, mould protection, high voltage clamping, clamping action and program control. Two-color injection molding machine It works in a similar way to the injection/molding control module. (4) Ejection control module The module mainly controls the actions and procedures of the mold ejection, ejection, core withdrawal, etc. It works in a similar way to the injection/molding control module.

Hydraulic system requirements (1) Injection molding machine from the beginning of the opening mold to the end of the opening mold, the middle to go through the opening mold slow - fast - slow - low pressure protection - high pressure lock - mold base multi-stage pressure preservation - pre-plastic - cooling - mold slow - fast - slow - ejection and other multi-action process. Each procedure has different pressure and speed requirements, that is, at different times or different positions in the flow, the flow and pressure are instantaneous and multistage changes, therefore, the reliability, reliability, silence and safety requirements of the hydraulic system of the injection molding machine and the hydraulic components of the system are very high.
