Description

Technical Field

[0001] The utility model relates to the technical field of injection molds, in particular to a novel injection mold. Background Art

[0002] With the advancement of science and technology and the changes in market demand, injection mold technology is also developing continuously. Injection mold is a tool used for plastic injection molding. It is usually composed of two or more metal parts to form a closed cavity. During the injection molding process, the plastic is melted and injected into the mold cavity through the syringe under high pressure. After the mold is cooled and solidified, the mold is opened to take out the molded plastic product.

[0003] After the plastic melt is formed in the mold, the plastic carries a lot of heat during molding, which causes the plastic product to form close thermal contact with the inner wall of the mold and adhere to the inner wall of the mold, forming a strong adhesion interface. As the plastic cools and solidifies, the adhesion force gradually increases, resulting in the plastic product being difficult to separate smoothly from the inner wall of the mold when the mold is opened, that is, the problem of demolding difficulty occurs.

[0004] In order to solve the above problems, a new injection mold is proposed in this application. Utility Model Content

[0005] Based on the technical problems existing in the background technology, the utility model proposes a novel injection mold.

[0007] A blow pipe is mounted on one side of the movable mold close to the fixed mold, and an air cylinder member connected to the movable mold is mounted on the outer periphery of the fixed mold, and the blow pipe and the air cylinder member are connected through an air guide hose;

[0008] The end of the air cylinder is connected with a striking piece for striking the fixed mold.

[0009] Preferably, the air cylinder component includes an air cylinder body, which is installed on the outer periphery of the fixed mold, an air cavity is opened in the air cylinder body, a piston part connected to the movable mold is slidably arranged in the air cavity, one end of the air guide hose is connected to the outer periphery of one end of the air cylinder body, and the air guide hose is connected to the air cavity, and the other end of the air guide hose is connected to the blowing pipe.

[0010] Preferably, the piston part comprises a piston body, the piston body is slidably arranged in the air cavity, a movable rod is installed at the end of the piston body, and one end of the movable rod away from the piston body slides through the other end of the cylinder body and is connected to the movable mold.

[0011] Preferably, the striking member includes a reciprocating rod and a striking block, the reciprocating rod slides through one end of the cylinder body and is connected to the piston body, the striking block is installed at the end of the reciprocating rod away from the piston body, and the striking block is located on the side of the fixed mold away from the movable mold, and a plurality of striking rods for striking the fixed mold are installed on the striking block.

[0012] Preferably, a molding chamber is provided in the fixed mold, and a plurality of air holes communicating with the molding chamber are provided on the blowing pipe.

[0013] The above technical solution of the utility model has the following beneficial technical effects:

[0014] By providing the air blowing pipe, air cylinder part, air guide hose and striking part, after the product is injection molded in the fixed mold, the injection molding machine can be used to drive the movable mold to repeatedly approach or move away from the fixed mold. In the process of the movable mold approaching or moving away from the fixed mold, the air cylinder part can drive the air cylinder part to move back and forth. When the air cylinder part moves back and forth, the gas can be continuously guided into the air blowing pipe through the air guide hose. The air blowing pipe is used to cool the product in the fixed mold. When the air cylinder part moves back and forth, the striking part can drive the striking part to strike the fixed mold back and forth, thereby vibrating the product in the fixed mold, making it easier for the product to be separated from the fixed mold. This structure can make it easier for the product to be separated from the fixed mold through the air blowing cooling and striking vibration structure, thereby improving the product demoulding effect.

[0018] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.

[0019] like Figure 1 and Figure 2As shown, a novel injection mold proposed by the utility model comprises a fixed mold 1 and a movable mold 2 which is separable from the fixed mold 1;

[0020] In this embodiment, a blowing pipe 3 is provided on the side of the movable mold 2 close to the fixed mold 1; a molding chamber is provided in the fixed mold 1, and a plurality of air holes connected to the molding chamber are provided on the blowing pipe 3; an air cylinder part 4 connected to the movable mold 2 is installed on the outer periphery of the fixed mold 1, and the blowing pipe 3 and the air cylinder part 4 are connected through an air guide hose 5.

[0021] In this embodiment, the air cylinder member 4 includes an air cylinder body 41, which is mounted on the outer periphery of the fixed mold 1, and an air cavity is provided in the air cylinder body 41, and a piston portion 42 connected to the movable mold 2 is slidably provided in the air cavity, one end of the air guide hose 5 is connected to the outer periphery of one end of the air cylinder body 41, and the air guide hose 5 is communicated with the air cavity, and the other end of the air guide hose 5 is communicated with the air blowing pipe 3. The piston portion 42 includes a piston body 421, which is slidably provided in the air cavity, and a movable rod 422 is installed at the end of the piston body 421, and one end of the movable rod 422 away from the piston body 421 slides through the other end of the air cylinder body 41 and is connected to the movable mold 2.

[0022] In this embodiment, the end of the gas cylinder member 4 is connected with a striking member 6 for striking the fixed mold 1. The striking member 6 includes a reciprocating rod 61 and a striking block 62. The reciprocating rod 61 slides through one end of the gas cylinder body 41 and is connected to the piston body 421. The striking block 62 is installed at one end of the reciprocating rod 61 away from the piston body 421, and the striking block 62 is located on the side of the fixed mold 1 away from the movable mold 2. A plurality of striking rods 63 for striking the fixed mold 1 are installed on the striking block 62.

[0023] It should be noted that: after the product is injection molded in the fixed mold 1, the injection molding machine can be used to drive the movable mold 2 to repeatedly approach or move away from the fixed mold 1. In the process of approaching or moving away from the fixed mold 1, the movable mold 2 can drive the piston body 421 to reciprocate in the cylinder body 41 through the movable rod 422. When the piston body 421 reciprocates in the cylinder body 41, the gas can be continuously guided to the air blowing pipe 3 through the air guide hose 5, and the product in the fixed mold 1 can be blown and cooled through the air holes opened on the air blowing pipe 3. When the piston body 421 reciprocates in the cylinder body 41, the reciprocating rod 61 can drive the striking block 62 to approach or move away from the fixed mold 1, and then the striking rod 63 on the striking block 62 strikes the fixed mold 1 reciprocatingly. When the fixed mold 1 is struck, the product in it will vibrate, making it easier for the product to be separated from the fixed mold 1. This structure can make it easier for the product to be separated from the fixed mold 1 through the structure of air blowing cooling and striking vibration, thereby improving the effect of product demoulding.
