Description

Technical Field

[0001] This application relates to the field of injection molding machines, and in particular to a discharging device for an injection molding machine. Background Art

[0002] An injection molding machine is the main molding equipment for making various shaped plastic products from thermoplastic or thermosetting materials using plastic molding dies. Its working principle is similar to that of a syringe used for injection. With the thrust of a screw (or plunger), the plastic in a molten state (i.e., viscous flow state) that has been plasticized is injected into a closed mold cavity, and the product is obtained after curing and shaping. Injection molding machines can form plastic products with complex shapes, precise dimensions, or metal inserts in one go, and have been widely used in various fields such as national defense, electromechanics, automobiles, transportation, building materials, packaging, agriculture, culture, education, health, and people's daily lives.

[0003] In the related art, reference can be made to the Chinese utility model patent with the authorization announcement number CN218453141U, which discloses an intermittent plastic injection molding machine. A thermoplastic mechanism is installed inside the box body, and the thermoplastic mechanism is connected to a crushing device at the top of the box body. A telescopic mold mechanism is arranged on one side of the thermoplastic mechanism. An exhaust gas filtering mechanism is installed on the inner top of the box body. The exhaust gas filtering mechanism includes a gas collecting hood, and the gas collecting hood is located on the inner top of the box body. An air inlet fan is installed inside the gas collecting hood, and the top of the gas collecting hood is connected to a filtering cylinder through a delivery pipe. In this intermittent plastic injection molding machine, by opening a connection port on the thermoplastic cylinder, the connection port is connected to the crushing device at the outer top of the box body. By installing an exhaust gas filtering mechanism on the inner top of the box body, the exhaust gas generated during the thermoplastic process is inside the box body, and under the action of the exhaust gas filtering mechanism, the exhaust gas is collected and filtered.

[0004] After the injection molding machine discharges the material, subsequent deburring and other treatments need to be carried out on the injection molded parts. However, the temperature of the injection molded parts is relatively high, and there is a risk of scalding when workers directly take and process them. Summary of the Utility Model
