[0024] It should be noted here that: through the setting of the demolding mechanism, under the pushing action of the pushing mechanism, the flipping and reciprocating shaking of the lower mold 103 are utilized to facilitate the separation of the solidified finished product in the lower mold 103, thereby realizing the rapid demolding of the rectangular silicone ring, reducing the production cycle of a single rectangular silicone ring, and further improving the molding efficiency of the rectangular silicone ring. When the rectangular silicone ring is demolded, the raw material injection and heating and curing in the injection molding of the rectangular silicone ring are carried out simultaneously, thereby reducing the waiting time between each process and further improving the molding efficiency of the rectangular silicone ring.

[0025] See also Figure 3 The connecting assembly shown in the figure includes a spline groove 301 provided at one end of the first connecting rod 202 close to the lower mold 103, a spline rod 302 is slidably connected to the spline groove 301, and an end of the spline rod 302 away from the first connecting rod 202 is connected to the lower mold 103 through a mounting rod 303;

[0026] It should be noted here that: through the setting of the connecting assembly, the lower mold 103 can be driven to rotate through the first connecting rod 202, and space can be provided for the shaking of the lower mold 103.

[0027] See also Figure 3 , as shown in the figure, mounting rings 401 are respectively provided on the side walls of the first connecting rod 202 and the mounting rod 303, a spring 402 is provided between the two mounting rings 401, the spring 402 is sleeved on the side wall of the first connecting rod 202, one end of the spring 402 is connected to one of the two mounting rings 401, and the other end of the spring 402 is rotatably connected to the other of the two mounting rings 401;

[0028] It should be noted here that: through the setting of the spring 402, when the push rod 503 passes over the triangular plate 502, the elastic action of the spring 402 will push the lower mold 103 to shake in the opposite direction, and one end of the spring 402 is rotatably connected to the mounting ring 401, thereby preventing the spring 402 from deforming.

[0029] See also Figure 3 The pushing mechanism shown in the figure includes a pushing plate 501, one end of the second connecting rod 203 away from the lower mold 103 is connected to the pushing plate 501, a side of the pushing plate 501 close to the fixed plate 201 is fixedly connected to a plurality of triangular plates 502, a side of the fixed plate 201 close to the pushing plate 501 is fixedly connected to a pushing rod 503, and the other end of the pushing rod 503 slides on the side wall of each triangular plate 502;

[0030] It should be noted here that the setting of the pushing mechanism facilitates the shaking of the lower mold 103.

[0031] Working principle: When the rectangular silicone ring is injection molded, the cylinder 105 is first used to push the upper mold 104 and the lower mold 103 together, and then the silicone raw material is injected into the lower mold 103 through the injection pipe 106. After the raw material is injected, the cylinder 105 drives the upper mold 104 away from the lower mold 103, and then the mounting plate 102 is rotated to rotate the lower mold 103 injected with the raw material out, and the next empty lower mold 103 is rotated to the bottom of the upper mold 104;

[0032] When the lower mold 103 into which the raw material is injected rotates out, the raw material will be solidified by the solidification mechanism. After the solidification is completed, the mold is rotated again. When the mold is rotated to a safe area, the motor 204 is started to drive the first connecting rod 202 to rotate. During the rotation of the first connecting rod 202, the lower mold 103 is turned over by the spline groove 301 and the spline rod 302.

[0033] During the flipping of the lower mold 103, the push plate 501 on the second connecting rod 203 will be synchronously driven to rotate. When the triangular plate 502 on the push plate 501 is against the push rod 503, the lower mold 103 will be pushed to shake under the mutual force and the guiding action of the spline groove 301 and the spline rod 302. When the push rod 503 passes over the triangular plate 502, the lower mold 103 will be pushed to shake in the opposite direction under the elastic action of the spring 402. Therefore, during the flipping of the lower mold 103, the triangular plate 502 and the push rod 503 are against each other, so that the lower mold 103 is reciprocated during the flipping process. Therefore, through the flipping and reciprocating shaking of the lower mold 103, the solidified finished product in the lower mold 103 is easily separated, thereby realizing the rapid demoulding of the rectangular silicone ring, reducing the production cycle of a single rectangular silicone ring, and further improving the molding efficiency of the rectangular silicone ring.

[0034] And when the rectangular silicone ring is demoulded, the raw material injection and heating and curing in the rectangular silicone ring injection molding are carried out simultaneously, thereby shortening the waiting time between each process and further improving the molding efficiency of the rectangular silicone ring.

The mounting plate 102 is provided with an annular hole 602, and the annular hole 602 is located below the three lower molds 103.

[0037] It should be noted here that: by setting up the collecting mechanism, it is convenient to collect the finished products demoulded from the lower mold 103, so as to facilitate the subsequent taking.
