By setting the guide block 7, the support frame 3 is provided with auxiliary support. The base plate 1 is fixedly connected to the upper end of the support, and a cylinder 9 is fixedly installed in the middle of the upper end of the support 8. The cylinder rod of the cylinder 9 passes through the support 8 and is slidably connected to the support 8. The lower end of the cylinder rod of the cylinder 9 is fixedly connected to the upper mold 10. The lower end of the upper mold 10 is fixedly connected to the guide pin 11. The upper end of the lower mold 4 is provided with an annular groove 13. By setting the guide pin 11 and the annular groove 13 to cooperate, misalignment between the upper mold 10 and the lower mold 4 is prevented. The upper mold 10 is fixedly connected to the inside of the feed pipe 12.
[0022] Please see Figure 2The adjustment mechanism 2 includes a motor 21, which is fixedly installed on the base plate 1. The rotating shaft of the motor 21 passes through the base plate 1 and is rotatably connected to the base plate 1. The rotating shaft of the motor 21 is fixedly connected to the support frame 3. A guide rod 22 is fixedly connected to the lower end of the support frame 3. A slide cylinder 23 is slidably connected to the outer side of the guide rod 22. A spring 24 is provided on the outer side of the guide rod 22. One end of the spring 24 is fixedly connected to the support frame 3, and the other end of the spring 24 is fixedly connected to the slide cylinder 23. By setting the spring 24, the slide cylinder 23 is elastically pressed down. A locking tooth 25 is fixedly connected to the lower end of the slide cylinder 23. The locking tooth 25 is slidably connected to the base plate 1. By driving the support frame 3 to rotate through the motor 21, the lower mold 4 can change positions. And by the spring 24 acting on the slide cylinder 23, the locking tooth 25 is inserted into the base plate 1, limiting the support frame 3. This allows the lower mold 4 to automatically change positions, making the device more efficient for silicon carbide electrostatic chuck injection molding.
[0023] Please see Figure 2 The ejection mechanism 5 includes a push rod 51. The push rod 51 is slidably connected inside the lower mold 4. A support ring 52 is fixedly connected to the upper end of the push rod 51. The support ring 52 is slidably connected to the lower mold 4. A top plate 53 is fixedly connected to the lower end of the push rod 51. An inclined block 54 is fixedly connected to the lower end of the top plate 53. A square rod 55 is fixedly connected to the upper end of the bottom plate 1. A baffle 56 is slidably connected to the outer side of the square rod 55. The baffle 56 is slidably connected to the inclined block 54. A compression spring 57 is provided on the outer side of the square rod 55. One end of the compression spring 57 is fixedly connected to the bottom plate 1, and the other end of the compression spring 57 is fixedly connected to the baffle 56. By setting the compression spring 57, the baffle 56 is elastically pushed upward. By moving the top plate 53 and contacting the baffle 56, the top plate 53 moves upward, which in turn causes the push rod 51 to drive the support ring 52 to move upward, thereby automatically lifting the formed silicon carbide electrostatic chuck, making it easier to demold the silicon carbide electrostatic chuck.
[0024] The specific implementation process of this utility model is as follows: In use, the motor 21 is started, driving the support frame 3 to rotate. The support frame 3 drives the guide rod 22 to move, the guide rod 22 drives the slide cylinder 23 to rotate, and the slide cylinder 23 drives the locking tooth 25 to move and misalign with the slot on the base plate 1, thereby causing the slide cylinder 23 to move upwards. This causes the spring 24 to be compressed. The rotation of the support frame 3 causes the lower mold 4 to change position. After the lower mold 4 completes its position change, the motor 21 stops rotating, and the support frame 3 stops rotating. At this time, the locking tooth 25 corresponds to the slot position of the current corresponding position. The spring 24 resets, causing the slide cylinder 23 to move downwards, thereby causing the locking tooth 25 to enter the slot, limiting the slide cylinder 23 and thus limiting the support frame 3. By driving the support frame 3 to rotate through the motor 21, the lower mold 4 can change its position, and through the action of the spring 24 on the slide cylinder 23, the locking tooth 25... Inserted into the base plate 1, it limits the support frame 3, thereby allowing the lower mold 4 to automatically switch positions, making the injection molding of silicon carbide electrostatic chucks more efficient. The cylinder 9 is activated, driving the cylinder rod to extend, which in turn moves the upper mold 10 downwards, causing the upper mold 10 and lower mold 4 to close. Then, material is fed into the mold cavity through the feed pipe 12 for injection molding. The movement of the support frame 3 moves the ejector rod 51, which in turn moves the top plate 53, which in turn moves the inclined block 54, causing it to contact the baffle 56. This causes the inclined block 54 to move upwards, which in turn moves the top plate 53 upwards, which in turn moves the ejector rod 51 upwards, which in turn moves the support ring 52 upwards, ejecting the molded silicon carbide electrostatic chuck from the lower mold 4, making demolding of the silicon carbide electrostatic chuck easier.
