[0030] The present disclosure will be described in detail below with reference to the drawings and in combination with the embodiments.

[0031] As Figures 1-3As shown in the figure, a control device for opening and closing a mold includes a guide rail 100, a movable block 201, a first clamping plate 202 and a second clamping plate 203. The first clamping plate 202 and the second clamping plate 203 are fixedly connected to the movable block 201, and the movable block 201 can move along the guide rail 100. The mold includes an upper mold 302 and a lower mold 301. One end of the upper mold 302 is rotatably connected to the lower mold 301, and the guide rail 100 is an arc-shaped structure. The fixture is conveyed on a conveyor belt, and the conveyor belt passes through the guide rail 100. The gap between the first clamping plate 202 and the second clamping plate 203 is greater than the thickness of the upper mold 302.

[0032] A first slider 204 is provided on the movable block 201, and a first chute 101 for the first slider 204 to move is provided on the guide rail 100.

[0033] A movable groove is provided on the second clamping plate 203. A support block 205 is provided in the movable groove. A support spring 2051 is provided at the bottom end of the support block 205. A through cavity is provided on the side wall of the movable groove, and the through cavity extends to the first slider 204. A fixing rod 206 is inserted into the through cavity. The fixing rod 206 moves along with the movement of the support block 205. An inclined groove is provided at one end of the fixing rod 206, and the inclined groove is provided below the support block 205. A second slider 2061 is provided on the fixing rod 206, and a second chute for the second slider 2061 to move is provided on the inner wall of the through cavity. A first return spring 2062 is provided on the second slider 2061, and the first return spring 2062 abuts against one end of the second chute.

[0034] An installation groove is provided on the first slider 204. A fixed block 207 and a movable block 208 are provided in the installation groove. A roller 2081 is provided on the movable block 208. The fixed block 207 moves along with the movement of the movable block 208. Specifically, a connecting rod 209 is hinged to the fixed block 207, and one end of the connecting rod 209 is hinged to the movable block 208. A second return spring 210 is provided on the fixed block 207, one end of the second return spring 210 abuts against the inner wall of the installation groove, an electromagnet 211 is provided in the installation groove, and a ferromagnetic block is provided on the fixed block 207.

[0035] After the molding part is injection-molded, the upper mold 302 is opened, and the lower mold 301 is placed on the conveyor belt to convey the mold. The manipulator takes out the molding part in the lower mold 301; the conveyor belt drives the mold to continue moving. At this time, the upper mold 302 is in an open state. The upper mold 302 moves between the first clamping plate 202 and the second clamping plate 203 of the movable block 201 at the top of the slide rail. The electromagnet 211 is energized to attract the fixed block 207 into the installation groove. The connecting rod 209 rotates to make the moving block 208 extend out of the installation groove. The roller 2081 abuts against the inner wall of the first chute 101 to drive the movable block 201 to move on the guide rail 100. The first clamping plate 202 abuts against the upper mold 302 to push the upper mold 302 to move. When the upper mold 302 is turned to an inclined state, the upper mold 302 falls downward under the action of gravity. The upper mold 302 falls on the support block 205 to push the support block 205 to move. At this time, under the action of inertia, the support block 205 moves a large distance. The support block 205 abuts against the inclined groove of the fixed rod 206 to push the fixed rod 206 to move. The fixed rod 206 extends out of the through cavity and abuts against the inner wall of the first chute 101 to fix the movable block 201, avoiding the forced movement of the movable block 201 due to the inertia when the upper mold 302 is turned down, and protecting the motor on the movable block 201; after the upper mold 302 falls and pushes the support block 205 to move, the support spring 2051 pushes the support block 205 to reset upward. The movable block 201 continues to drive the upper mold 302 to turn over. The upper mold 302 abuts against the second clamping plate 203 until the movable block 201 moves to the bottom end of the guide rail 100. Then the upper mold 302 covers the lower mold 301. At this time, the upper mold 302 is separated from the second clamping plate 203. The upper mold 302 is between the first clamping plate 202 and the second clamping plate 203. The conveyor belt continues to drive the closed mold to move, and the mold performs the next round of foaming and molding operation.
