Problems solved by technology

The all-electric injection molding machine with this structure has the following problems: first, because the moving device is driven by a geared motor, the moving device and the fixed plate are connected by a spring, and the nozzle contact force between the nozzle and the mold depends only on the force of the spring. The elastic deformation is used to realize the detection, so it is impossible to accurately control the contact force of the nozzle during injection and non-injection; second, because the nozzle and the mold always maintain consistent contact force when the injection molding machine is working normally, the nozzle and the mold during the mold opening and closing process There will be relative movement between them, resulting in problems such as easy wear of the nozzle or glue leakage

Abstract

The invention discloses an injection moulding machine which includes a die locking system and an injection moulding system, wherein the die locking system includes a fixed die plate. The injection moulding system is provided with a servo hydraulic system which is used for driving the injection moulding system to move relative to the fixed die plate. The servo hydraulic system includes a total-moving oil cylinder and a total-moving oil cylinder hydraulic control mechanism which are communicated with each other through an oil pipe. The injection moulding machine is high in universality, is high in sensitivity and control precision, can alleviate nozzle abrasion and prevent rubber leakage, is better in die compatibility and technological adaptability and is low in cost.

Description

technical field [0001] The invention relates to a molding device, in particular to an injection molding machine. Background technique [0002] Injection molding machine is the main molding equipment for making thermoplastics or thermosetting plastics into various shapes of plastic products using plastic molding molds. Traditional all-electric injection molding machines generally include a mold clamping system driven by a servo motor and an injection system. The injection system includes a moving device driven by a geared motor. Features. The all-electric injection molding machine with this structure has the following problems: First, because the moving device is driven by a geared motor, the moving device and the fixed plate are connected by a spring, and the nozzle contact force between the nozzle and the mold depends only on the force of the spring. The elastic deformation is used to realize the detection, so it is impossible to accurately control the nozzle contact forc...
