Embodiment approach

[0019] In the first embodiment of the present invention, please continue to refer to figure 1 Shown. A first barrel passage 61, a second barrel passage 71 and a third barrel passage 51 are penetrated inside the barrel body 1. A first connecting channel 62, a second connecting channel 72 and a third connecting channel 52 are provided inside the connecting body 2. A first nozzle passage 63, a second nozzle passage 73, and a third nozzle passage 53 are arranged inside the nozzle 3. The first injection channel includes a first cartridge channel 61 located in the cartridge body 1, a first connection channel 62 located in the connecting body 2, and a first nozzle channel 63 located in the nozzle 3. The second injection channel includes a second cartridge channel 71 located in the cartridge body 1, a second connection channel 72 located in the connecting body 2, and a second nozzle channel 73 located in the nozzle 3. The third injection passage includes a third barrel passage 51 lo...

Abstract

The invention discloses an injection device of an injection molding machine, which comprises a charging barrel main body, a connecting main body and a nozzle, wherein the charging barrel main body is connected with the connecting main body which is connected with the nozzle; the charging barrel main body and the connecting main body are respectively provided with a first injection channel, a second injection channel and a third injection channel which are respectively connected with the nozzle; and the first injection channel, the second injection channel and the third injection channel which are arranged on the charging barrel main body are respectively connected with an exhaust device. By adopting the first injection channels, the second injection channels and the third injection channels, the injection device effectively realizes a plurality of times of injection on one injection molding machine, thus effectively reducing the loss of injection pressure, avoiding residue of melted materials in a flow channel, and guaranteeing the performances of products. Furthermore, by adopting an exhaust channel and a vacuum pump, the injection device effectively enables negative pressure to be formed in the exhaust channel, accelerating the discharge of gas and improving the production efficiency and the product quality.

Description

Technical field [0001] The invention relates to an injection device, in particular to an injection device for an injection molding machine. Background technique [0002] Injection molding machine is a kind of main molding equipment that uses plastic molding molds to make plastic products of various shapes. High pressure is applied to molten plastics to inject and fill the mold cavity. In the traditional process, if you need to inject different plastic products with multiple layers, you first need to complete the inner layer injection on an injection molding machine, and then take the second and third injections on other injection molding machines. Secondary molding. However, this traditional injection molding process is complicated, time-consuming and labor-intensive, and the processed products tend to retain residual stress, which reduces the molding quality of plastic products. Summary of the invention [0003] The purpose of the present invention is to provide an injection de...
