Description

Technical Field

[0001] The invention relates to the technical field of injection molds, in particular to an injection mold which is easy to eject and demould. Background Art

[0002] Injection molds are molds used for plastic injection molding. Injection molds are tools that match plastic molding machines in the plastic processing industry, giving plastic products complete configurations and precise dimensions. The design and manufacture of injection molds are important links to ensure the precision and appearance of plastic products. They are installed on plastic injection machines for use. The basic structure of injection molds includes two parts: the movable mold and the fixed mold. The movable mold is the part that contacts the raw material and needs to ensure smoothness and precision, while the fixed mold is the part that fixes the mold structure. The pouring system is also called the runner system, which refers to the runner part after the raw material enters the cavity from the nozzle, including The main channel, cold material hole, branch channel and gate are directly related to the molding quality and production efficiency of injection molded products. The injection mold is large in size and heavy in weight. It needs to be moved with lifting equipment and wire rope. Some injection molded parts commonly found on the market are relatively weak. When being ejected and demolded, they are easily damaged and deformed, or demolding is more laborious, affecting the injection molding efficiency. After the top mold structure is connected to the injection molding machine, the connection position is prone to wear or looseness, and voids are prone to occur, affecting the injection molding accuracy. During the process of lifting and moving the injection mold, it is easy to shake and has poor stability. Summary of the invention

[0003] The disclosed embodiment relates to an injection mold which is easy to eject and demould. When the mold body needs to be hoisted, after the external part is connected to the mold body, the hoisting wire rope can be controlled to be connected to the fixed head. During the traction and lifting process, the wire rope pulls the fixed head and the vertical plate component to rise together. While rising, the movable shaft component slides and displaces inside the guide groove. Since the guide groove is an inclined structure, the vertical plate component moves inward, so that the push plate component contacts and clamps the side of the mold body, thereby generating a force to clamp the mold body and improve stability. At the same time, the push plate component drives the extrusion head to move outward together. The extrusion head is inserted into the fixed head and slides inside to extrude the wire rope, thereby improving the fixing effect of the wire rope, and improving the hoisting stability and connection strength.

[0021] The working principle of this embodiment is as follows: when the mold body 1 is needed, the external part 3 is controlled to be connected with the mold body 1 in advance, and then the wire rope to be hoisted is controlled to be connected with the fixed head 306, and then the wire rope, the fixed head 306 and the vertical plate component 305 are controlled to rise together through the hoisting equipment, and the vertical plate component 305 is forced to rise, so that the movable shaft component 303 slides inside the guide groove 301, and at the same time, the force plate 304 is pulled inside the control plate 302. Since the guide groove 301 is an inclined structure, the vertical plate component 305 The push plate component 307 is moved inward by force, and contacts the side of the mold body 1, generating a force to clamp the mold body 1, thereby improving the fixing effect and stability of the mold body 1. After the push plate component 307 is forced, it drives the extrusion head 308 to move outward together, and the extrusion head 308 squeezes the wire rope to improve the fixing effect of the wire rope. When the mold body 1 moves to the use position, the injection molding machine controls the injection molding machine connecting rod 204 to connect with the connecting head 201, and controls the sliding head 207 to insert into the slot 203. The control bolt is inserted into the inner groove 208 to firmly fix the sliding head 207 and the pushing structure 205. The pushing structure 205 is pressed against the injection molding machine connecting rod 204. At the same time, the clamping structure 206 clamps the injection molding machine connecting rod 204 to improve the connection effect and avoid looseness or shaking. Then, the mold body 1 is controlled to be used to make the injection molded part inside the mold body 1. After the injection molding is completed, the top mold structure 2 is controlled to rise, and the piston push rod 108 is controlled to operate. The piston push rod 108 squeezes the set 106. The air inside controls the displacement of the push rod assembly 107 by pressure, and the push rod assembly 107 drives the moving plate 103 and the auxiliary assembly 104 to move together. The auxiliary assembly 104 pushes the ejector assembly 102 upward, generating a preliminary force to push the injection molded part. When the push rod assembly 107 moves to the position of the connecting pipe 105, the airflow enters the inside of the connecting pipe 105, and then is discharged through the moving groove 101 and the inside of the ejector assembly 102. With the help of the airflow impact force and pressure, the injection molded part is conveniently demolded, which improves the demolding efficiency.
