A guide protrusion is installed on the inner edge of the directional tube 2, and the guide protrusion is movably docked in the 7-shaped channel.

[0021] Beneficial effects of the present invention:

[0022] 1. The insulating cylinder manufacturing mold changes the positions of the linkage frame, the bidirectional lead screw and the inner groove disk through the engagement relationship between the linkage shaft and the linkage frame. The different changes of the straight line segment position can be controlled under the cooperation of the scale on the linkage frame surface. Under the threaded relationship between the bidirectional lead screw and the inner groove disk, the inner groove disk moves and cooperates with the linkage frame, and the bearing piece 1 can be unfolded or folded, so as to control the radius of the semicircular segment position. Under the action of the guide frame and the guide frame, the bearing piece 1 can be linked with the bearing piece 2 to synchronously approach or deviate from the position of the bearing seat when unfolding or folding, so as to make detailed adjustments when manufacturing insulating cylinders of different sizes;

[0023] 2. The insulating tube manufacturing mold of the present invention can make it difficult for the docking plate and the docking seat to deviate from their positions when docking through the configuration of the directional tube 1 and the constraint tube. At this time, the inner mold mechanism can be in the most central position on the bearing platform, further improving the casting accuracy of the insulating tube. In the initial state, the constraint frame 1 will be supported by the periphery of the docking plate, and gradually enter the directional tube 1 with the docking seat. At this time, the constraint frame 1 is supported by the docking seat. When the docking seat is separated from the tip position of the constraint frame 1, under the characteristics of the torsion-type elastic member 1, the tip of the constraint frame 1 changes and touches the upper surface of the bearing part of the docking seat. At this time, the principle of the constraint frame 2 is the same as the above and is supported by the inner edge of the bearing part of the docking seat, thereby ensuring the accuracy of the inner mold mechanism during assembly and the sealing effect between the inner mold mechanism and the bearing platform.

[0024] 3. When the insulating tube manufacturing mold of the present invention completely enters the directional tube one through the bearing part of the docking seat, the limiting tube will gradually penetrate and extend out of the connecting channel, and the directional tube two will be moved upward. The inner edge of the directional tube two will act on the linkage column, and the linkage column will extend and move on the straight-section elastic member three. At this time, the linkage column drives the constraint arm to unfold, and then the linkage circle one is rotated, so that the guide protrusion enters the second section of the 7-shaped channel. At this time, the telescopic state of the directional tube two can be limited, and the linkage circle one is rotated. At this time, the guide protrusion enters the second section of the 7-shaped channel, and the linkage circle two is rotated synchronously. Under the action of the bite, the constraint cap rotates. Under the characteristics of the thread connection, the constraint cap will move toward the back of the docking disk when it rotates. At this time, the bearing part of the docking seat and the docking disk are closely contacted to limit it, so that the inner mold mechanism can be quickly installed and disassembled.

DETAILED DESCRIPTION

[0045] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0046] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention.

In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0049] Example 1, reference Figure 1 and 2 , an insulating tube manufacturing mold, comprising a bearing platform 100, an inner mold mechanism 200 and an outer mold 300; the outer mold 300 is arranged on the upper surface of the bearing platform 100, the inner mold mechanism 200 is arranged on the inner edge of the outer mold 300, the inner mold mechanism 200 is located on the upper surface of the bearing platform 100, an elastic layer 101 is arranged on the surface of the bearing platform 100, wherein the elastic layer 101 ensures the sealing effect of the inner mold mechanism 200 and the outer mold 300 and the bearing platform 100 when they are connected, a bearing column 102 is arranged at the corner position of the lower surface of the bearing platform 100, a bearing frame 103 is arranged at the inner edge position of the bearing column 102, and a long channel 104 is milled on the bearing platform 100;

[0050] Reference Figure 2 , 3, 4, 5 and 6, the inner mold mechanism 200 includes a bearing seat 201, a bidirectional screw 202, a bearing piece 1 205 and a bearing piece 2 211, the bearing seat 201 is arranged in the middle position of the bearing platform 100, the bidirectional screw 202 is parallel to the edge position of the bearing seat 201, a guide seat 215 is embedded in the long channel 104, and the guide seat 215 is movably connected to the bidirectional screw 202, wherein the guide seat 215 and the long channel 104 are embedded, so that the guide seat 215 cannot rotate, and the normal rotation of the bidirectional screw 202 can be guaranteed at this time, and the guide seat 215 can telescopically move in the long channel 104 to meet the position changes of the bearing plate 206, the inner pattern plate 203 and the bidirectional screw 202 during the telescopic movement, the outer thread of the bidirectional screw 202 is connected to the inner pattern plate 203, and the inner pattern plate 203 is movably connected to the connecting frame 204, and the bearing piece 1 205 is movably connected to the inner pattern plate 203. Connected to the outward portion of the connecting frame 204, a linkage frame 208 is arranged on one side of the inner pattern disc 203 facing the bearing seat 201, and the linkage frame 208 is telescopically movable in the bearing seat 201, and the inner edge of the linkage frame 208 is milled with a tooth-notch-type pattern, and a linkage shaft 209 is movably arranged in the bearing seat 201, and the surface of the linkage shaft 209 is milled with a tooth-notch-type pattern, and the linkage frame 208 is engaged with the linkage shaft 209. A telescopic frame 210 is arranged on the adjacent side of the bearing seat 201 close to the inner pattern disc 203, and a bearing sheet 211 is arranged on the movable part of the telescopic frame 210, and a guide frame 213 is arranged on the inner edge of the bearing sheet 211, and a guide frame 214 is arranged on the bearing sheet 1 205, and the guide frame 213 telescopically moves in the guide frame 214, wherein the linkage frame 208 and the telescopic frame 210 can be correspondingly provided with scales, so as to know the size of the semicircle and the straight line segment of the adjusted inner mold mechanism 200;

[0051] The linkage shaft 209 is operated, and the linkage frame 208 undergoes telescopic movement under the effect of the bite, and at this time, the positions of the bidirectional lead screw 202 and the inner grooved disk 203 can be changed. This is based on the fact that the guide seat 215 can telescopically move on the long channel 104, and the different changes in the position of the straight line segment can be controlled under the cooperation of the scale on the surface of the linkage frame 208. Subsequently, the bidirectional lead screw 202 is operated, and under the effect of the thread connection, the inner grooved disk 203 undergoes relative movement. In this process, the linkage frame 208 can also carry the seat 201 to achieve vertical movement without affecting the bite of the linkage shaft 209 and the linkage frame 208. At this time, Under the action of the connecting frame 204, the carrier sheet 1 205 is unfolded and folded to control the radius of the semicircular segment position. Under the action of the guide frame 213 and the guide frame 214, the carrier sheet 1 205 can be linked with the carrier sheet 211 to synchronously approach or deviate from the position of the carrier seat 201 when unfolding or folding. At the same time, the carrier sheet 1 205 will not affect the position of the carrier sheet 211 when following the position change of the bidirectional lead screw 202 and the inner pattern plate 203. Under the action of the telescopic frame 210, the radius of the semicircular segment position can be obtained, so that detailed adjustments can be made when manufacturing insulating cylinders of different sizes.

[0052] When pouring the insulating cylinder, after the linkage shaft 209 and the bidirectional lead screw 202 are rotated to the specified number of revolutions, a layer of PE plate is hooped around the outer ring of the carrier sheet 1 205 and the carrier sheet 2 211. It should be noted that the thickness of the PE plate has been calculated when the linkage shaft 209 and the bidirectional lead screw 202 are controlled and adjusted. At this time, the space between the PE plate and the outer mold 300 is the size of the insulating cylinder to be poured, and a grid can be added in the space to increase the strength of the insulating cylinder after pouring. This device is used for insulating cylinders with a certain range of size differences. When the required size difference is too large, the large-sized insulating cylinder can be manufactured by using the overall device for large sizes.

[0053] Reference Figure 5 and 7 The middle section of the bidirectional lead screw 202 is sleeved with a bearing plate 206, a telescopic frame 207 is installed between the bearing plate 206 and the bearing sheet 205, and a T frame 216 is arranged on one side of the bearing plate 206 facing the bearing seat 201, and the T frame 216 telescopically moves in the bearing seat 201;

[0054] After the position of the carrier plate 206 changes due to the threaded connection, the telescopic frame 207 can further guide the unfolding and folding movement of the carrier plate 205, thereby improving the stability of the carrier plate 205 during adjustment. Under the action of the T frame 216, the stability of the bidirectional lead screw 202 and the inner pattern plate 203 during position change is further improved;

[0055] Example 2, refer to Figure 1 ,2 , 5 and 8, a docking seat 421 is installed at the bottom of the bearing seat 201, and the bottom protruding position of the docking seat 421 is a disc-shaped bearing part. A constraint module 402 is telescopically moved in the bearing platform 100, wherein the constraint module 402 is provided with a guide in the bearing platform 100 to ensure that it will not be separated and rotated. A bearing cylinder 400 is installed on the upper surface of the bearing frame 103, and a docking plate 401 is installed at the position where the bearing cylinder 400 extends into the constraint module 402;

[0056] Reference Figure 8 , 9 and 11, the constraint module 402 includes an directional cylinder 1 403, a constraint cylinder 410, a constraint frame 1 411, a constraint frame 2 412 and a constraint unit 413, the directional cylinder 1 403 is telescopic in the bearing cylinder 400, the constraint cylinder 410 is arranged at the inner edge position of the bearing cylinder 400 extending into a section of the directional cylinder 1 403, the constraint cylinder 410 and the directional cylinder 1 403 are docked by using a directional protrusion 1, the bearing cylinder 400 is milled with a directional channel at a position close to the directional protrusion 1, and the directional protrusion 1 performs telescopic movement in the directional channel; the directional cylinder The first constraint frame 411 is distributed at an equal angle at the peripheral position of the first constraint frame 403, and the second constraint frame 412 is distributed at an equal angle on the inner edge surface of the constraint cylinder 410. By installing the first constraint frame 411 and the second constraint frame 412, the docking seat 421 can be tightly docked with the docking plate 401. The first directional cylinder 403 faces the inner mold mechanism 200 and is located at a peripheral position. A storage channel is reserved. The first constraint frame 411 is movably docked in the storage channel. The docking point between the first constraint frame 411 and the storage channel is provided with a twisting elastic member 1.

The constraint frame 2 412 and the docking frame are movably docked, and a torsion-rotating elastic member 2 is arranged at the movable part of the constraint frame 2 412 and the docking frame, and its form is the same as that of the torsion-rotating elastic member 1, but the direction of action is different;

[0057] The configuration of the directional cylinder 403 and the constraint cylinder 410 can make it difficult for the docking plate 401 and the docking seat 421 to deviate from their positions when docking. When the directional cylinder 403 is controlled to change its position by telescopic movement, the constraint cylinder 410 changes its position along with it during this process. The bearing part of the docking seat 421 will be located at the inner edge of the directional cylinder 403. At the same time, the constraint cylinder 410 extends into the inner edge of the bearing part of the docking seat 421, thereby further constraining the position of the docking seat 421. At this time, the inner mold mechanism 200 can be located at the most central position on the bearing platform 100, further improving the casting accuracy of the insulating cylinder and improving the assembly efficiency of the inner mold mechanism 200 on the bearing platform 100.

[0058] The restraining frame 411 changes position synchronously with the directional tube 403. In the initial state, the restraining frame 411 is resisted by the periphery of the docking plate 401, and gradually enters the directional tube 403 with the docking seat 421. At this time, the restraining frame 411 is resisted by the docking seat 421. When the docking seat 421 is separated from the tip of the restraining frame 411, due to the characteristics of the torsion elastic member 1, the tip of the restraining frame 411 changes and touches the upper surface of the bearing part of the docking seat 421. At this time, the docking seat 421 is in close contact with the docking plate 401. At the same time, the second constraint frame 412 moves synchronously with the constraint cylinder 410. At this time, the second constraint frame 412 is supported by the inner edge of the docking plate 401, and gradually enters the directional cylinder 1 403 with the docking seat 421. At this time, the second constraint frame 412 is supported by the inner edge of the docking seat 421. When the inner edge of the docking seat 421 is separated from the tip of the second constraint frame 412, under the characteristics of the second torsion elastic member, the tip of the second constraint frame 412 changes and touches the inner edge of the bearing part of the docking seat 421, and the docking seat 421 is further closely contacted with the docking plate 401.

After the control restraining arm 416 is moved, it can directly act on the surface of the bearing part of the docking seat 421, and under the supporting action of the restraining cap 419, the bearing part of the docking seat 421 and the docking plate 401 can be further restrained in position after being fitted and docked, and the sealing effect during the casting of the insulating tube is guaranteed;
