Injection molding pressure adjustable injection molding device based on light sensation control

Abstract

The invention relates to the technical field of plastic injection molding and discloses an injection molding pressure adjustable injection molding device based on light sensation control. The injection molding device comprises a base and a housing. An injection molding assembly is movably connected outside the base, a protecting shell is movably connected in the base, a cam is movably connected inthe protecting shell, a spring I is movably connected in the protecting shell, a gate is movably connected outside the spring I, a die is movably connected in the base, and a movable block is movablyconnected in the housing. Under interaction of the base, the injection molding assembly, the protecting shell, the cam, the spring I, the gate and the die, a raw material is in a constant temperaturestate before flowing into the die, so that it brings a huge benefit to form a plastic then, and therefore, the product quality is guaranteed to the maximum extent. Moreover, the amount of the raw material flowing into the die can be controlled by a driving power supply, so that rejected products due to excessive raw materials can be avoided.

Description

technical field [0001] The invention relates to the technical field of plastic injection molding, in particular to an injection molding device with adjustable injection pressure based on light perception control. Background technique [0002] Injection molding is a method of producing shapes for industrial products. Products usually use rubber injection molding and plastic injection molding. Injection molding can also be divided into injection molding molding method and die casting method. Injection molding machine is the main molding equipment for making thermoplastics or thermosetting materials into various shapes of plastic products using plastic molding molds. Injection molding is realized through injection molding machines and molds. Rubber injection molding is a production method in which rubber is injected directly from the barrel into the mold for vulcanization. Although rubber injection molding is an intermittent operation, the molding cycle is short, the product...

AI Technical Summary

Problems solved by technology

[0006] Aiming at the deficiencies of the prior art, the present invention provides an injection molding device with adjustable injection pressure based on light sensing control, which has the advantages of adjustable pressure and precise control, and solves the problem of traditional injection molding machines that cannot take into account the pressure And the constant temperature effect during injection molding, which will cause the thickness of each part to be different during plastic molding. Some injection molding machines can achieve greater injection pressure, but the constant temperature effect is not good, and some injection molding machines can guarantee the constant temperature effect during injection molding. , but the injection pressure is not ideal, and the control of injection pressure will directly affect the fluidity of injection molding raw materials, so that the finished product is prone to defective products during the forming process
