[0023] Specifically, the first cylinder 11 contracts to drive the rotating plate 10 to move, thereby driving the second connecting rod 9 to rotate around the rotating connection of the second mounting column 6, so that the first connecting rod 8 drives the second sliding plate 4 to slide in the first sliding groove 7, and then the first sliding plate 3 drives the mounting plate 2 to move upward. When the second sliding plate 4 slides into the first sliding groove 7 in the second mounting column 6, the mounting plate 2 and the first sliding plate 3 will flip ninety degrees.

[0024] Reference Figure 1 The pushing mechanism includes a support plate 12, the side wall of the support plate 12 is fixedly connected to the surface of a second mounting column 6, an electric telescopic rod 13 is installed on the upper surface of the support plate 12, and the output end of the electric telescopic rod 13 is fixedly connected to a pushing plate 14, and the lower surface of the pushing plate 14 is higher than the upper surface of the second mounting column 6.

[0025] Specifically, the support plate 12 supports the electric telescopic rod 13 , making it easier to install the electric telescopic rod 13 .

[0026] The outer wall of the mounting plate 2 fits with the inner wall of the lower mold 1 , one side of the first sliding plate 3 fits with the inner wall of one side of the lower mold 1 , and the top surfaces of the first sliding plate 3 and the second sliding plate 4 fit with the top surface of the lower mold 1 .

[0027] Specifically, the arrangement of the mounting plate 2, the first sliding plate 3 and the second sliding plate 4 will not affect the effect of the injection molding and the use of the device.

[0028] Reference Figure 2 A first fixing column 15 is fixedly connected between the two second connecting rods 9 , between the two rotating plates 10 , and between the two first connecting rods 8 .

[0029] Specifically, the provision of the first fixing column 15 helps to improve the stability of the movement between the first connecting rod 8 , the second connecting rod 9 and the rotating plate 10 .

[0030] Reference Figure 3 A second fixing column 16 is fixedly connected between the two first mounting columns 5 and between the two second mounting columns 6 .

[0031] Specifically, the provision of the second fixing column 16 helps to improve the stability of the movement between the mounting plate 2 and the first sliding plate 3, and prevents the first sliding plate 3 from tilting due to excessive force.

[0036] Working principle: When the device is used, the second cylinder 20 is started to drive the fixed plate 19 to slide downward in the second slide groove 18, thereby driving the upper mold 23 to approach the lower mold 1, so that the positioning block 21 enters the positioning groove 22, and the lower surface of the upper mold 23 is in contact with the upper surface of the lower mold 1 and closed. After the injection molding of the raw material is completed and cooled, the upper mold 23 is lifted up to a certain position by the second cylinder 20, and the first cylinder 11 is started to contract and drive the rotating plate 10 to move, thereby driving the second connecting rod 9 to rotate with the second mounting column 6 rotating connection as the axis, thereby making the first connecting rod 8 drive the second sliding plate 4 to slide in the first slide groove 7, thereby making the first sliding plate 3 drive the mounting plate 2 to move upward, thereby driving the cooled and molded product to move upward and detach from the lower mold 1, which can be used for cooling. The molded product can be quickly demoulded. When the second sliding plate 4 slides into the first sliding groove 7 in the second mounting column 6, the mounting plate 2 and the first sliding plate 3 will drive the finished product to flip 90 degrees.
