Description

Technical Field

[0001] The invention relates to the technical field of injection molding devices, and more particularly to an injection molding device used for producing automobile rearview mirrors. Background Art

[0002] The injection device is one of the molding equipment used to manufacture automobile rearview mirrors. Among them, the common injection device mainly consists of a base, an inverted U-shaped hanging beam, an injection crucible structure, an injection punch, a guide pipe, a support buffer base, a lower pressure plate and a mold holder and other mechanisms. The production process of the automobile rearview mirror by the injection device is as follows: pour the metal liquid into the injection crucible structure, and adjust the telescopic rod to make the upper pressure plate body press the lower pressure plate, and fix the automobile rearview mirror mold at the same time; control the operation of the punching machine to drive the punching connecting rod and the injection punch to descend, and spray the metal liquid into the mold through the injection bin and the guide pipe; after the injection is completed, start the cooling pipeline to allow the coolant to enter the cooling coil through the water injection cooling connecting pipe for cooling; after the finished product is cooled, release the telescopic rod and take out the finished product; In the process of producing automobile rearview mirrors with injection molding, we found that the connection ends of the guide tube, stamping components and production molds are prone to falling off or loosening. The main reasons for this problem are: 1. The connectors of the guide tube are loose: Since the connectors are affected by vibration and impact during long-term use, wear and tear is very likely to occur between components; 2. External factors: If excessive force or improper operation methods are used during operation, the guide tube may be damaged or loosened; When the above phenomenon occurs, the following effects will occur: 1. Flow control impact: The looseness of the guide tube may cause changes in its internal channel, thereby affecting the flow through it; 2. Increased pressure loss: When the guide tube is loose, the fluid may encounter additional resistance when passing through, resulting in increased pressure loss; 3. Increased leakage risk. Loose guide tubes may cause gaps in the connection, thereby increasing the risk of leakage. The above effects cause the automobile rearview mirror to be unable to be produced normally, resulting in certain economic losses; Therefore, we are in urgent need of a press-injection device for automobile rearview mirror production to solve the above-mentioned technical problems.

At the same time, the two groups of electric control valves input stable currents, and the compressed air inside the auxiliary hollow column 601 enters into the limit plate 607 through the input groove 608, driving the limit plate 607 to move into the main countersunk groove. When the pressure value inside the limit plate 607 reaches a certain value, the torsion spring plate 610 is driven to rotate, and the compressed air inside the limit plate 607 is input into the telescopic plate 609, driving the telescopic plate 609 to increase its length, and then it is stuck into the inner wall of the main countersunk groove, so that the limit plate 607 is fixed and limited in the main countersunk groove; When the connection between the guide tube 507 and the outer wall of the jet device 1 and the air pump 501 is not complete, the length of the corresponding hollow pillar 602 changes, which causes the pressure data collected by the air pressure sensor on the auxiliary hollow pillar 601 and the hollow pillar 602 to change.
