[0025] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0026] As described in the background section, different specifications of machine heads have different diameters and different lowest points during disassembly. The rapid alternation of old and new machine heads requires a dual-station rotatable design, and the stability cannot be effectively guaranteed when installing a new machine head.

[0027] To solve this technical problem, this utility model provides a tooling trolley for changing the head of a molding machine, which includes a base plate 1, a top plate 2 directly above the base plate 1, protrusions 3 installed at the four corners of the top of the base plate 1 and the four corners of the bottom of the top plate 2, lifting support frames 4 installed on the sides of the base plate 1 and the top plate 2 through the protrusions 3, a rotating disk is provided at the front end of the top of the top plate 2, a bracket plate 8 is installed on the top of the rotating disk, two support grooves 9 are symmetrically opened on the surface of the bracket plate 8, a stabilizing mechanism 10 is installed on the surface of the top plate 2, the stabilizing mechanism 10 includes a locking component and a supporting component, a rectangular groove 11 is opened on the surface of the top plate 2 near the rear, the locking component is movably disposed in the rectangular groove 11, and the supporting component is disposed at the front end of the top plate 2.

[0028] The scissor lift support frame 4 driven by cylinder 5 can effectively adjust the height of the top plate 2, facilitating the disassembly of machine heads of different specifications and reducing the labor intensity of operators. The bracket plate 8 is rotatably installed above the top plate 2, and the operator can manually rotate the bracket plate 8 to quickly interchange the positions of the two machine heads, making it easy to place the new machine head in the installation position. The drive gear 12 is moved by the rectangular plate 16, so that the locking column 15 is accurately embedded in the semi-circular groove 26 of the bracket plate 8 to achieve rigid locking and reduce positioning errors. Example 1

[0029] Please refer to Figure 1A cylinder 5 is installed on the surface of the base plate 1. The lifting support frame 4 is set as a scissor lifting assembly, and the bottom ends of the two lifting support frames 4 are connected to the crossbar 6. The output end of the cylinder 5 is connected to the crossbar 6. The cylinder 5 provides power, and its output end is connected to the crossbar 6. When the cylinder 5 extends, it pushes the crossbar 6 to move to the rear of the device, causing the bottom ends of the two scissor lifting support frames 4 to unfold to the side, thereby lowering the top plate 2 and the bracket plate 8 above it. When the cylinder 5 retracts, the crossbar 6 moves forward, the bottom ends of the lifting support frames 4 retract inward, and the top plate 2 and the bracket plate 8 above it lower. The mechanical power of the cylinder 5 replaces the traditional manual lifting handle. The operator does not need to repeatedly manually rotate the handle. Especially in the scenario of changing heavy machine heads, it can greatly reduce manpower consumption and shorten the lifting time. The scissor lifting assembly is an existing mature mechanism, which will not be elaborated on here. Example 2

[0030] Further optimizations to Example 1, specifically, such as... Figure 2-5 As shown: The locking assembly includes a gear 12, which is rotatably mounted inside a rectangular groove 11. A smooth surface 13 is provided at the end of the gear 12, and an extension rod 14 is fixedly mounted on the surface of the smooth surface 13. A locking post 15 is fixedly mounted at the top of the extension rod 14. A rectangular plate 16 is movably disposed below the rectangular groove 11, and a rack 17 is provided on the surface of the rectangular plate 16, meshing with the gear 12. By moving the rectangular plate 16 back and forth, the rack 17 on its surface can drive the gear 12 to rotate within the rectangular groove 11. When the gear 12 rotates, it drives the coaxial smooth surface 13 and the extension rod 14 to rotate synchronously, causing the locking post 15 at the top to lift upwards or fall downwards. When the rectangular plate 16 moves backwards, the gear 12 drives the locking post 15 to rise; when the rectangular plate 16 moves in the opposite direction, the gear 12 drives the locking post 15 to fall, and the extension rod 14 and the locking post 15 retract into the rectangular groove 11.

[0031] A protruding strip is fixedly installed at the end of the bracket plate 8. A semi-circular groove 26 is formed on the surface of the protruding strip. The semi-circular groove 26 corresponds to the locking post 15. The semi-circular groove 26 and the locking post 15 are matched in shape to form a surface contact positioning structure. When the rectangular plate 16 moves backward, the gear 12 drives the locking post 15 to rise. The locking post 15 will be locked in the semi-circular groove 26. When the rectangular plate 16 moves in the opposite direction, the gear 12 drives the locking post 15 to fall. The locking post 15 will move out of the semi-circular groove 26. Through this mechanism, the operator only needs to apply a small force to move the rectangular plate 16, and the locking post 15 will generate a large locking force through the gear 12 transmission.

[0032] A positioning plate 19 is fixedly installed at the bottom rear of the top plate 2. A guide rod 20 is provided below the top plate 2. A lead screw 21 is fixedly installed at the rear end of the guide rod 20. The lead screw 21 passes through the positioning plate 19 through a thread. A sleeve 18 is fixedly installed at the bottom of the rectangular plate 16. The sleeve 18 is movably fitted onto the surface of the guide rod 20. Two retaining rings are fixedly installed on the surface of the guide rod 20. The two retaining rings are respectively located in front of and behind the sleeve 18. The diameter of the retaining rings is larger than the diameter of the sleeve 18. The lead screw 21 passes through the positioning plate 19 through a thread. When the lead screw 21 is rotated, due to the threaded engagement, the lead screw 21 will move linearly along the axial direction. The rear end of the lead screw 21 is fixedly connected to the guide rod 20. Therefore, when the lead screw 21 moves, it drives the guide rod 20 to move back and forth synchronously. The rectangular plate 16 is fitted onto the guide rod 20 through the sleeve 18. When the guide rod 20 moves, it pushes or pulls the sleeve 18, causing the rectangular plate 16 to translate along the axial direction of the guide rod 20.

[0033] An L-shaped frame 23 is fixedly installed below the top plate 2 and on both sides of the rectangular groove 11. The end of the rectangular plate 16 is movably engaged in the L-shaped frame 23. The end of the rectangular plate 16 is embedded in the gap between the horizontal limiting edge of the L-shaped frame 23 and the top plate 2, forming a lateral limiting and vertical support. When the rectangular plate 16 moves back and forth under the drive of the guide rod 20, its end slides along the horizontal limiting edge of the L-shaped frame 23, ensuring that the rectangular plate 16 only moves in a straight line in the front and back direction and cannot deviate left or right or sway up and down.

[0034] The support assembly includes a lifting plate 24, which is movably mounted on the front end of the top plate 2. The front end of the guide rod 20 is connected to the surface of the lifting plate 24 via a pivot and a connecting rod 25. The guide rod 20 moves back and forth by rotating the lead screw 21. Its front end is connected to one end of the connecting rod 25 via a pivot, and the other end of the connecting rod 25 is connected to the lifting plate 24 via a pivot. When the guide rod 20 moves forward, it pulls the lifting plate 24 down along the front end of the top plate 2 via the connecting rod 25. When the guide rod 20 moves backward, it pulls the lifting plate 24 up along the front end of the top plate 2 via the connecting rod 25. After the lifting plate 24 is raised, its top can support the front end of the bracket plate 8, further ensuring the stability of the bracket plate 8. Example 3

[0035] Further optimizations to Example 2, such as Figure 1 , 6 As shown: The surface of the lifting plate 24 is provided with a T-shaped slider, and the front end of the top plate 2 is provided with a T-shaped groove. The T-shaped slider is slidably installed in the T-shaped groove. When the guide rod 20 pushes the lifting plate 24 through the connecting rod 25, the T-shaped slider makes a linear lifting and lowering motion in the T-shaped groove to ensure that the movement trajectory of the lifting plate 24 is strictly vertical and to avoid tilting or jamming caused by lateral force.

[0036] A turntable 22 is fixedly installed at the rear end of the lead screw 21; through the turntable 22, the operator can control the lead screw 21 to rotate.

[0037] A push handle 27 is bolted to the rear end of the top plate 2, and casters 7 are installed at the four corners of the bottom of the bottom plate 1. The push handle 27 is bolted to the rear end of the top plate 2. The operator can move the top plate 2 and the bottom plate 1 by applying horizontal pushing or pulling force. Since the top plate 2 and the bottom plate 1 are connected by the lifting support frame 4, the force of the push handle 27 is transmitted through the top plate 2 to the casters 7 at the bottom of the bottom plate 1, so as to realize the overall movement of the tooling trolley.

[0038] The process of using the tooling trolley for replacing the molding machine head provided by this utility model is as follows: First, push the trolley under the molding machine head to ensure that the trolley is parked stably and avoids tilting. Then, operate cylinder 5 to control the lifting of the scissor-type lifting support frame 4. Cylinder 5 retracts, pulling the crossbar 6 forward, the lifting support frame 4 retracts, and the top plate 2 and bracket plate 8 rise. Remove the old machine head and place it in the support groove 9. Then, manually rotate the bracket plate 8. Under the action of the rotating disc, the positions of the two support grooves 9 are interchanged, and the new machine head is placed in the installation position. Then, rotate the turntable 22 to drive the lead screw 21 to rotate, causing the guide rod 20 to move backward. The guide rod 20 pushes the rectangular plate 16 to move backward. The rack 17 drives the gear 12 to rotate. The gear 12 drives the extension rod 14 and the locking post 15 to lift upward and lock into the semi-circular groove 26 of the bracket plate 8. At the same time, the connecting rod 25 pushes the lifting plate 24. As it rises, the lifting plate 24 rises vertically along the T-slot, abutting against the front end of the bracket plate 8 to provide additional support and prevent the machine head from tilting. The bracket plate 8 is now in a stable state, making it convenient for workers to operate.
