A conical plate frame 136 is fixedly installed on the support frame 135. The conical plate frame 136 is used to prevent the pillars from flying out. The conical plate frame 136 is fixedly matched with the supporting circular plate 120. The upper surface of the material distribution plate 130 and the inner side surface of the conical plate frame 136 are both provided with a rubber buffer layer.

The lower surface of the supporting circular plate 120 is fixedly provided with a discharging convex ring 121 which contacts and cooperates with the discharging push pin 106.

[0026] The working principle of a production equipment capable of quickly forming a comb disclosed in the present invention is as follows: controlling a first drive motor 127, the output shaft of the first drive motor 127 can drive one of the lead screws 124 to rotate, and while the lead screw 124 rotates, the other lead screw 124 is also driven to rotate through a synchronous toothed disc 123 and a synchronous chain 125, the rotation of the two lead screws 124 will drive a rotating ring bracket 117 to move along the axis, the movement of the rotating ring bracket 117 will drive a rotating ring 116 to move, the rotating ring 116 will drive a rotating bobbin 115 to move, the rotating bobbin 115 drives a reinforcing frame 114 to move, and the reinforcing frame 114 drives an upper template 101 to move, thereby being able to change the distance between the upper template 101 and the lower template 102 (the hexagonal sliding column 103 and the lower template 102 slide relative to each other).

[0027] Initially, the upper mold plate 101 and the lower mold plate 102 are in a closed state, and the external molten plastic is pressurized and injected into the collecting pipe 112 through the sliding sleeve 113, and then distributed to the corresponding molded grooves through multiple injection pipes 111 (the injection pipe 111, the collecting pipe 112, and the sliding sleeve 113 are all embedded with heating coils to prevent the molten plastic from solidifying and causing blockage). When the molten plastic fills the molded grooves, the air in the grooves needs to be discharged during this process. During the injection process, the second drive motor 128 needs to be started. The output shaft of the second drive motor 128 drives the driven pulley 118 to rotate through the transmission belt 119. The rotation of the driven pulley 118 drives the rotating bobbin 115 to rotate. The rotation of the rotating bobbin 115 drives the reinforcing frame 114 to rotate. The rotation of the reinforcing frame 114 drives the upper mold plate 101 to rotate. The rotation of the reinforcing frame 114 also drives the injection pipe 111 and the collecting pipe 112 to rotate. The tube 112 rotates (the collecting tube 112 and the sliding sleeve 113 rotate relative to each other), the rotation of the upper template 101 will drive the hexagonal sliding column 103 to rotate, and the rotation of the hexagonal sliding column 103 will drive the lower template 102 to rotate. At this time, the upper template 101 and the lower template 102 will rotate synchronously, and the plastic melt inside the molded groove will flow toward the edge under the action of centrifugal force. Since the density of air is lower than that of the plastic melt, the air will move toward the center of rotation of the upper template 101, and then be discharged through the semicircular exhaust groove 109. After the plastic melt in the molded groove is filled, the injection of the plastic melt is stopped, and then cooling and shaping are waited (the cooling speed of the upper template 101 and the lower template 102 can be accelerated by the high-speed rotation of the upper template 101 and the lower template 102, or water cooling can be used to set a circulating water channel inside the upper template 101 and the lower template 102 for cooling).

[0028] The speed of the second drive motor 128 is reduced, and finally the first drive motor 127 is controlled to move the upper template 101 upward, and the upper template 101 is separated from the lower template 102. Due to the draft angle, the surface area of ​​the upper template 101 in contact with the formed comb is larger than the surface area in contact with the lower template 102, so the formed comb will adhere to the upper template 101. When the unloading push pin 106 on the upper template 101 moves to contact the unloading convex ring 121, the return spring 107 will be compressed, and the unloading push pin 106 will be relative to the unloading hole 108. Slide, so that the discharge push pin 106 is inserted into the groove opened on the upper template 101, and the formed comb is pushed down. During this process, the comb is always in a rotating state, so when it falls, it will be separated between the opposite surfaces of the upper template 101 and the lower template 102 by the centrifugal force, and then fall onto the distribution plate 130. The rotation of the distribution plate 130 can drive the formed comb to rotate. When the comb contacts the discharge paddle 134, it will be guided to separate from the distribution plate 130. A transmission belt can be set at the separation position to transmit the comb to the specified position. The rotation of the distribution plate 130 is driven by the third drive motor 132. The output shaft of the third drive motor 132 drives the distribution gear 131 to rotate, the distribution gear 131 drives the distribution gear ring 133 to rotate, and the distribution gear ring 133 drives the distribution plate 130 to rotate.
