[0011] Preferably, there are multiple limiting blocks, and the multiple limiting blocks are in two groups, and are evenly arranged on one side of the outer surface of the left and right support rods.
[0012] Preferably, one end of the support rod contacts one side of the outer surface of the movable ring and passes through one side of the outer surface of the movable ring to the other side of the outer surface of the movable ring.
[0013] Preferably, one end of the device tube is fixedly connected to one side of the inner wall of the device box, and the other end contacts the other side of the inner wall of the device box, penetrates one side of the inner wall of the device box, extends to one side of the outer surface of the device box, and is fixedly connected to the device box.
[0014] Preferably, one end of the auxiliary tube contacts one side of the outer surface of the device tube, penetrates one side of the outer surface of the device tube, enters the device tube, and is fixedly connected to the device tube.
[0015] Preferably, one end of the connecting rod is provided with a device ring, and the device ring is fixedly connected to one end of the connecting rod, and the support rod passes through the device ring.
[0016] The auxiliary tube has upper and lower sliding grooves on both sides of its inner wall. The outer surface of the upper and lower sliding grooves contacts the inner wall of the auxiliary tube and extends through the inner wall to the outer surface of the auxiliary tube. The insertion rod is installed inside the auxiliary tube, and a sliding rod is installed on the outer surface of the insertion rod. One end of the sliding rod is fixedly connected to the outer surface of the insertion rod, and the other end is slidably connected to the inner wall of the upper and lower sliding grooves, which makes the insertion rod more stable when it moves up and down.
[0017] Furthermore, a limiting groove is provided on one side of the inner wall of the device box, and one side of the outer surface of the limiting groove contacts one side of the inner wall of the device box and penetrates one side of the inner wall of the device box to one side of the outer surface of the device box. A sliding rod is provided on one side of the outer surface of the connecting seat, and one end of the sliding rod is fixedly connected to one side of the outer surface of the connecting seat, while the other end is slidably connected to the inner wall of the limiting groove, thereby allowing the connecting seat to move only left and right. The connecting seat is fixedly connected to the slot plate, thereby allowing the slot plate to move only left and right. There are two shafts, and the contact ends of the two shafts are connected by bearings. A limiting groove is provided on the inner ring of the bearing, and one end of the limiting groove is slidably connected to the inner wall of the slot plate, thereby allowing one end of the shaft to move left and right when the slot plate moves left and right, thereby causing the lower end of the shaft to push the movable rod and the insertion rod to move up and down.
[0018] The device ring moves left and right on the outer surface of the support rod, and one end of the movable tube contacts one side of the outer surface of the device ring, penetrates one side of the outer surface of the device ring, and extends to one side of the inner wall of the device ring, where it is fixedly connected. This allows the device ring to drive the connecting rod to move left and right as the movable tube moves. Limit grooves are provided on both sides of the inner wall of the movable tube, with one side of the outer surface of the limit groove contacting one side of the inner wall of the movable tube and penetrating one side of the inner wall of the movable tube into the tube. A fixed rod is located inside the movable tube, and sliders are provided on both sides of the outer surface of the fixed rod. One side of the outer surface of the slider is fixedly connected to one side of the outer surface of the fixed rod, and the other end is connected to the inner wall of the limit groove. The sliding connection allows the fixed rod to move only up and down without disengaging from the movable tube. A fixing hole is provided on the outer surface of the support rod, penetrating the support rod and fitting the fixed rod. This allows the fixed rod to engage with the fixing hole during up and down movement, thus fixing the position of the movable tube. When the movable tube is fixed, the insertion rod is precisely engaged with the heating rod. A sliding groove is provided on one side of the outer surface of the device box, with one side of the groove contacting and penetrating the outer surface of the device box to the inner wall of the device box. The movable tube passes through the sliding groove and is slidably connected to it, allowing the movable tube to move left and right.
[0019] Preferably, one end of the threaded rod is fixedly connected to one side of the outer surface of the auxiliary groove plate, and the other end contacts one side of the inner wall of the auxiliary box, penetrates one side of the inner wall of the auxiliary box, extends to one side of the outer surface of the auxiliary box, and extends to one side of the outer surface of the cover plate.
[0020] A ring groove is provided on one side of the outer surface of the cover plate, and one side of the outer surface of the ring groove contacts one side of the outer surface of the cover plate and penetrates one side of the outer surface of the cover plate into the cover plate. A limiting slide rod is provided on the outer surface of the threaded ring, and one end of the limiting slide rod is fixedly connected to one side of the outer surface of the threaded ring, while the other end is slidably connected to the inner wall of the ring groove. This makes the threaded ring more stable when it rotates. The threaded ring and the threaded rod are threadedly connected, so that when the threaded ring rotates, the threaded rod drives the auxiliary groove plate to move up and down.
[0021] Furthermore, a rotating rod is provided on one side of the outer surface of the turntable, and there are two rotating rods. The right rotating rod is slidably connected to the inner wall of the auxiliary groove plate, and the left rotating rod is in contact with the auxiliary support rod. Thus, when the threaded ring rotates, the threaded rod drives the auxiliary groove plate to move up and down, thereby causing the turntable to rotate. This allows the left rotating rod to push the auxiliary support rod and the limiting support rod to move.
[0022] Compared with the prior art, the present invention provides a component production mold, which has the following beneficial effects:
[0023] 1. This invention, through a movable tube set in the base device, causes the connecting rod to move left and right, which in turn causes the connecting seat to move the slot plate left and right, thereby causing one end of the shaft to move left and right. When one end of the shaft moves left and right, the other end of the shaft moves up and down, thereby causing the insert rod to move up and down. When the insert rod is inserted into the heating rod, the heating rod is fixed. When the insert rod is disengaged from the heating rod, the heating rod can be removed, thereby achieving the effect of replacing the heating rod.
[0024] 2. In this invention, a support rod is installed inside the base device, and a limiting block is provided on one side of the outer surface of the support rod. The limiting blocks have different lengths, with the lowest limiting block being the longest and its length being greater than the inner diameter of the movable ring. This ensures that when the lowest movable ring moves downward, it is restricted by the lowest limiting block, and when the second movable ring moves downward, the second limiting block restricts the second movable ring. This allows the heating rod to be regularly positioned inside the device tank.
[0025] 3. In this invention, a threaded ring is installed inside the cover plate device, and the threaded ring is threadedly connected to a threaded rod. When the threaded ring rotates, the threaded rod moves up and down, causing the turntable to rotate. A rotating rod is provided on one side of the outer surface of the turntable, and one side of the outer surface of the rotating rod contacts one side of the outer surface of the auxiliary support rod. When the rotating rod rotates, it presses against the auxiliary support rod, causing the limiting support rod to insert into the base device. When the rotating rod disengages from the auxiliary support rod, the auxiliary support rod moves under the action of a spring, causing the limiting support rod to disengage from the base device. This makes the cover plate device easy to remove and allows for internal observation. Attached Figure Description

[0043] Through the above technical solution, the auxiliary tube 109 has upper and lower sliding grooves on the left and right sides of its inner wall. The outer surface of the upper and lower sliding grooves contacts the inner wall of the auxiliary tube 109 and penetrates the inner wall of the auxiliary tube 109 to the outer surface of the auxiliary tube 109. The insertion rod 110 is installed inside the auxiliary tube 109. A sliding rod is provided on the outer surface of the insertion rod 110. One end of the sliding rod is fixedly connected to the outer surface of the insertion rod 110, and the other end is slidably connected to the inner wall of the upper and lower sliding grooves. This makes the insertion rod 110 more stable when it moves up and down.
[0044] Furthermore, a limiting groove is provided on one side of the inner wall of the device box 106, and one side of the outer surface of the limiting groove contacts one side of the inner wall of the device box 106 and penetrates one side of the inner wall of the device box 106 to one side of the outer surface of the device box 106. A sliding rod is provided on one side of the outer surface of the connecting seat 114, and one end of the sliding rod is fixedly connected to one side of the outer surface of the connecting seat 114, and the other end is slidably connected to the inner wall of the limiting groove, so that the connecting seat 114 can only move left and right.

[0045] The device ring moves left and right on the outer surface of the support rod 116, and one end of the movable tube 117 contacts one side of the outer surface of the device ring, penetrates one side of the outer surface of the device ring, and extends to one side of the inner wall of the device ring, where it is fixedly connected. This allows the device ring to drive the connecting rod 115 to move left and right when the movable tube 117 moves left and right. Limit grooves are provided on both sides of the inner wall of the movable tube 117, and one side of the outer surface of the limit groove contacts one side of the inner wall of the movable tube 117, penetrating one side of the inner wall of the movable tube 117 and extending into the movable tube 117. The fixed rod 118 is located inside the movable tube 117, and sliders are provided on both sides of the outer surface of the fixed rod 118. One side of the outer surface of the slider is fixedly connected to one side of the outer surface of the fixed rod 118, and the other end is slidably connected to the inner wall of the limit groove. The fixed rod 118 can only move up and down and will not disengage from the movable tube 117. The outer surface of the support rod 116 is provided with a fixing hole, which penetrates the support rod 116 and is adapted to the fixed rod 118. When the fixed rod 118 moves up and down, it is inserted into the fixing hole, thereby fixing the position of the movable tube 117.

The right rotating rod is slidably connected to the inner wall of the auxiliary groove plate 207, and the left rotating rod is in contact with the auxiliary support rod 205. Thus, when the threaded ring 209 rotates, the threaded rod 208 drives the auxiliary groove plate 207 to move up and down, thereby causing the turntable 206 to rotate. This allows the left rotating rod to push the auxiliary support rod 205 and the limiting support rod 204 to move.
[0049] In use, when replacing the heating rod 108, the fixed rod 118 is moved up and down. When the fixed rod 118 is disengaged from the support rod 116, the movable tube 117 is moved left and right, causing the connecting rod 115 and the slot plate 113 to move. This causes one end of the shaft 112 to move left and right, and the other end of the shaft 112 to drive the movable rod 111 and the insertion rod 110 to move up and down. When the insertion rod 110 is inserted into the heating rod 108, the position of the heating rod 108 is fixed. When the insertion rod 110 is disengaged from the heating rod 108, the heating rod 108 can be removed, thus achieving the effect of replacing the heating rod 108.
