Description

Technical Field

[0001] This utility model relates to the field of molding equipment technology, and in particular to an automatic molding device for ACT lower cover. Background Technology

[0002] The ACT lower cover includes a plastic shell and a metal component embedded in the plastic shell. One end of the metal component has a pin that extends from the tail end of the plastic shell. During the molding process of the ACT lower cover, the metal component is first assembled into the mold before injection molding. Most common injection molding devices have only one upper mold and one lower mold. After the metal component is placed into the lower mold, the upper mold is closed for injection molding. After injection molding is complete, the molds are separated, the product is removed from the lower mold, and a new metal component is placed before the next injection molding can be performed. This method is inefficient. Therefore, this invention proposes an automatic molding device for the ACT lower cover. Utility Model Content

A third cylinder 1008 with its output end facing the second material receiving block 1003 is horizontally fixed at the top of the mounting block 1004. A limiting push block 1009 matching the limiting recess 1007 is connected to the push rod of the third cylinder 1008. A gripper cylinder 1010 is provided between the first material receiving block 1002 and the second material receiving block 1003. Two positioning grippers 1011 distributed along the Y direction are connected to the output end of the gripper cylinder 1010. The metal part 5 to be assembled is placed on the first support block 1002 and the second support block 1003. The front section of the metal part 5 is inserted into the limiting gap 1006, the middle section of the metal part 5 is inserted between the two positioning claws 1011, and the tail end of the metal part 5 is L-shaped and falls into the limiting recess 1007. The third cylinder 1008 drives the limiting push block 1009 to retract, and the limiting push block 1009 is pushed into the limiting recess 1007, thereby assembling the metal part 5. The metal part 5 is positioned in the X direction. The gripper cylinder 1010 drives the two positioning grippers 1011 to come into contact with each other and clamp the metal part 5, thereby positioning the metal part 5 in the Y direction. After positioning, the first multi-axis robot 701 drives the second vacuum nozzle 705 to suck up the positioned metal part 5. Then, the gripper cylinder 1010 and the third cylinder 1008 are reset. The first multi-axis robot 701 transports and installs the metal part onto the lower mold 3.

[0036] The working process of this application is as follows: In the initial state, both lower molds 3 are unloaded, the slider 307 is away from the contour block 301, the push rod of the fourth cylinder 611 is in a retracted state, and the mounting plate 604 is in a vertical state. The first multi-axis robot 701 drives the second vacuum nozzle 705 to pick up and transport the metal part 5 to be assembled onto the lower mold 3. The positioning protrusion 302 extends into the positioning hole on the metal part 5, and the pin of the metal part 5 perpendicular to its end face extends into the positioning groove 304, thereby aligning the metal part 5 with the mold 301. The metal part 5 is positioned in the positioning recess on its lower end face. The first cylinder 308 drives the second contour block 309 to move closer to the contour block 301. The pins of the metal part 5 extend into the pin clearance hole 311. The turntable 2 rotates 180°, and the lower mold 30 carrying the metal part 5 rotates to the bottom of the upper mold 4. The unloaded lower mold rotates to the right. The press drives the upper mold 4 to close downwards and perform injection molding. At the same time, the first multi-axis robot 701 assembles the metal part into another unloaded lower mold 3. After injection molding is completed, the upper mold 4 separates. The turntable 2 rotates 180° again, the lower mold containing the product moves to the right for material handling and unloading, and the lower mold containing the metal part 5 moves to the left for injection molding. By alternately feeding material from the two lower molds, continuous injection molding is achieved, greatly improving production efficiency. When the lower mold 3 containing the product moves to the right, the ejector rod of the fourth cylinder 611 extends, thereby driving the mounting plate 604 to rotate horizontally. The material handling assembly 609 moves above the product, and the second cylinder 6095 drives the second mounting plate 6093 downwards. The first vacuum nozzle 6094 then sucks up the product. On the upper surface of the product, the second cylinder 6095 resets, thereby grabbing the product away from the lower mold 3. The push rod of the fourth cylinder 611 retracts, pulling the mounting plate 604 to rotate to the horizontal. The second multi-axis machine 801 drives the pneumatic gripper 803 to clamp the product. The first vacuum nozzle 6094 releases the product. The second multi-axis machine 801 transports the product onto the conveyor belt 901. The product is conveyed and cooled along the conveyor belt 901. After cooling, the product slides down the unloading slide plate 902 into the receiving frame 903.

[0037] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
