[0025] A second linkage assembly is assembled between the first mold 5 and the movable mold 8, which is used to slide the movable mold 8 away from or close to the mold groove on the first mold 5. The second linkage assembly includes a first cylinder 2 and a second cylinder 9. The first cylinder 2 is bolted to the workbench 3, and the output shaft of the first cylinder 2 is horizontally arranged along the length direction of the workbench 3.

The second cylinder 9 is bolted to the right end of the second mold 7, and the output shaft of the second cylinder 9 is horizontally arranged along the length direction of the workbench 3. A connecting plate is welded and fixed on the movable mold 8, and the second cylinder 9 is located on the left side of the connecting plate and the output shaft of the second cylinder 9 is fixedly connected to the connecting plate.

[0026] The first cylinder 2 and the second cylinder 9 are both double-acting cylinders and the cylinder bodies are connected through a pipeline. The air inlet end of the first cylinder 2 is connected to the air outlet end of the second cylinder 9 through a pipeline, and the air outlet end of the first cylinder 2 is connected to the air inlet end of the second cylinder 9 through another pipeline.

[0027] A second groove 16 is cut horizontally along the width direction on the top of the workbench 3, and the second groove 16 is located between the two limiting grooves 4. A push plate 6 is limitedly slidably engaged in the second groove 16, and the push plate 6 is engaged with the first screw rod 13 through a first linkage assembly, which is used to drive the push plate 6 to slide along the second groove 16.

[0028] The second linkage assembly includes a first bevel gear 11 and a second bevel gear 12. A second screw 15 is placed horizontally in the second groove 16 along the width direction of the workbench 3, and the second screw 15 is rotatably connected to the workbench 3. The second screw 15 passes through the push plate 6 and is threadedly connected to the push plate 6. The second screw 15 rotates forward and penetrates into the first groove 10. The first bevel gear 11 is located in the first groove 10 and is coaxially fixedly connected to the second screw 15. The second bevel gear 12 is displaced in the first groove 10 and is coaxially fixedly connected to the first screw 13. The first bevel gear 11 is meshed with the second bevel gear 12.

[0029] Working principle: When closing the mold, start the motor 1, the output shaft of the motor 1 drives the first screw 13 to rotate, and the first screw 13 pushes the first mold 5 and the second mold 7 to slide closer to each other along the limiting groove 4. In this process, the first screw 13 drives the second bevel gear 12 to rotate, the second bevel gear 12 drives the first bevel gear 11 to rotate, the first bevel gear 11 drives the second screw 15 to rotate, and the second screw 15 drives the push plate 6 to move from front to back along the second groove 16.

[0030] The first mold 5 and the second mold 7 do not contact the push plate 6 during the sliding process.

[0031] When the first mold 5 slides close to the second mold 7, the first mold 5 drives the output shaft of the first cylinder 2 to extend. The gas in the chamber on the right side of the piston of the first cylinder 2 enters the chamber of the second cylinder 9 on the right side of the piston of the second cylinder 9 from the gas outlet of the first cylinder 2 through the connected pipe and the gas inlet of the second cylinder 9. At the same time, the gas in the chamber on the left side of the piston of the second cylinder 9 enters the chamber of the first cylinder 2 on the left side of the piston of the first cylinder 2 from the gas outlet of the second cylinder 9 through the connected pipe and the gas inlet of the first cylinder 2.

[0032] During this process, the gas pushes the piston in the second cylinder 9 to drive the output shaft to retract, and the output shaft of the second cylinder 9 drives the movable mold 8 to approach the mold groove of the first mold 5 along the through groove of the second mold 7 through the connecting plate. At the same time, the movable mold 8 drives the connected limit block to slide along the movable groove 14.

[0033] The movable mold 8 does not contact the push plate 6 during the sliding process.

[0034] When the first mold 5 and the second mold 7 are in contact and finally sealed, the movable mold 8 is butted against the mold groove of the first mold 5, thereby forming a mold cavity for lampshade molding. At this time, the push plate 6 is located behind the first mold 5 and the second mold 7. At the same time, the limit block on the movable mold 8 is butted against the second mold 7.

[0035] Then, injection molding is performed into the mold cavity.

[0036] During demoulding, the output shaft of the motor 1 is reversed relative to that during mold closing. At this time, the output shaft of the motor 1 drives the first screw 13 to reverse, and the first screw 13 pushes the first mold 5 and the second mold 7 to slide away from each other along the limiting groove 4. During this process, the first screw 13 drives the second bevel gear 12 to reverse, the second bevel gear 12 drives the first bevel gear 11 to reverse, the first bevel gear 1 drives the second screw 15 to reverse, and the second screw 15 pushes the push plate 6 to move from back to front along the second groove 16.

[0037] The first mold 5 and the second mold 7 do not contact the push plate 6 during the sliding process.

[0038] During the process of the first mold 5 sliding away from the second mold 7, the first mold 5 drives the output shaft of the first cylinder 2 to retract. The gas in the chamber on the left side of the piston of the first cylinder 2 enters the chamber of the second cylinder 9 on the left side of the piston of the second cylinder 9 from the air inlet end of the first cylinder 2 through the connected pipe and the air outlet end of the second cylinder 9. At the same time, the gas in the chamber on the right side of the piston of the second cylinder 9 enters the chamber of the first cylinder 2 on the right side of the piston of the first cylinder 2 from the air inlet end of the second cylinder 9 through the connected pipe and the air outlet end of the first cylinder 2.

[0039] During this process, the gas pushes the piston in the second cylinder 9 to drive the output shaft to extend, and the output shaft of the second cylinder 9 drives the movable mold 8 to move away from the mold groove of the first mold 5 along the through groove of the second mold 7 through the connecting plate. At the same time, the movable mold 8 drives the connected limit block to slide along the movable groove 14.

[0040] The movable mold 8 does not contact the push plate 6 during the sliding process.

[0041] When the movable mold 8 slides out of the mold groove of the first mold 5, the molded lampshade falls onto the workbench 3. As the push plate 6 continues to slide, the push plate 6 pushes the molded lampshade out from between the first mold 5 and the second mold 7, so as not to affect the next mold closing and improve production efficiency.

[0042] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
