Technical Field

[0001] This utility model relates to the field of PPR pipe mold hanger technology, and in particular to a mold hanger for PPR pipe production. Background Technology

[0002] In the production of PPR pipes, processes such as injection molding, blow molding, extrusion, die casting or forging, smelting, stamping, and stretching are involved, requiring the use of corresponding molds. Sometimes, these molds need to be changed or their positions adjusted. Therefore, an existing technology for a mold hanger used in PPR pipe production, with publication number CN220976270U, ​​involves sliding a third gear along a square rod to separate it from the second gear, thus releasing the limit on the rotating rod. This allows the hooks to be pulled along the sliding rod, enabling adjustment of the distance between the hooks on both sides according to the mold dimensions. After adjustment, the third gear is released, and it resets under the spring force, re-engaging with the second gear and preventing it from rotating. This prevents the rotating rod from rotating, thus limiting the position of the two hooks and facilitating stable mold lifting.

[0003] However, the existing technology has a fixed shell above the hook, which limits the height of the mold that the hook can clamp. Once the height of the mold exceeds the height of the hook, the existing technology cannot be used smoothly. In other words, the existing technology is limited in terms of the height of the mold to which it is applicable. Utility Model Content

[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] like Figures 1-4 As shown, a mold hanger for PPR pipe production includes two sliding seats 1, which are arranged in parallel and located on both sides of the mold. A movable seat 2 is inserted into the upper surface of the sliding seat 1. The bottom edge of the movable seat 2 is inserted into the upper surface of the sliding seat 1, and a connecting strip 12 is fixedly installed on the movable seat 2 relative to the bottom edge of the inner wall. An electric push rod 11 is arranged horizontally and perpendicular to the roller 3 between the connecting strip 12 and the sliding seat 1. In actual use, the two sliding seats 1 are moved to the long side of the mold and fit against the mold. After the mold is lifted by traction, the electric push rod 11 retracts and pulls the connecting strip 12 to drive the movable seat 2 to slide in the direction of the mold from the sliding seat 1.

[0024] The top edge of the movable base 2 has a horizontally set slot 18, and several slide blocks 6 are slidably installed in the slot 18. The upper surface of the movable base 2 is hollowed out along the extension direction of the slot 18. The slide blocks 6 are connected to the hollowed-out parts of the surface of the movable base 2 by bolts. By connecting with the hollowed-out parts at different positions, it is easy to adjust the installation spacing of the slide blocks 6. A vertically set insert 5 is set through the upper surface of the slide block 6. The bottom edge of the insert 5 extends horizontally to form a block 17 for overlapping with the bottom edge of the mold. When the mold is lifted, the movable base 2 moves away from the mold to make the block 17 misaligned with the mold. After the mold is lifted, the movable base 2 moves towards the mold until the block 17 moves to the bottom of the mold. At this time, the mold can be put down, and the block 17 on both sides can be used to support the bottom sides of the mold, which is convenient for transferring the mold by pushing the sliding frame.

[0025] A horizontally arranged reel 3 is rotatably connected to the inner wall of the sliding seat 1. At least two winding frames 9 are fitted on the surface of the reel 3. The winding spool of the winding frame 9 is inserted into the surface of the reel 3, and the frame of the winding frame 9 is inserted into the inner top edge of the movable seat 2. One end of the stranded wire wound on the winding spool inside the winding frame 9 is provided with a pin 10 for threaded connection with the positioning hole on the mold surface. A motor 15 is embedded and fixedly installed on the side of the movable seat 2, which is distributed at the same height as the reel 3. The main shaft of the motor 15 passes through the surface of the movable seat 2 and is fixedly connected to one end of the reel 3. The surface of the reel 3 has a section along the central axis that is connected to the winding frame 9. The inner winding spool passes through the slot 14. The top of the movable frame is fixedly installed with a rail 16 that is parallel to the spool 3 and passes through the wire threading frame. The position of the winding frame 9 can be easily adjusted by personnel through the insertion of the frame part of the winding frame 9 into the top of the movable frame. Then, the motor 15 drives the spool 3 to rotate, and with the cooperation of the slot 14, the winding spool in the winding frame 9 rotates, realizing the release of the stranded wire wrapped on the surface. This makes it convenient for the pin 10 to be threadedly connected to the positioning hole on the surface of the mold or to be inserted in the horizontal direction. The winding spool can then be used to wind up the stranded wire to lift the mold.

[0026] Several inserts 5 on the same movable seat 2 are connected to a horizontally arranged crossbeam 4 on their side top edges. The crossbeam 4 is located above the movable seat 2. Hydraulic rods 7 are embedded in the outer top edge of the movable seat 2 near both ends of the crossbeam 4. The hydraulic rods 7 are vertically arranged and their telescopic ends are fixedly connected to the surface of the crossbeam 4. By extending the hydraulic rods 7, the crossbeam 4 can drive the inserts 5 on its surface to rise and fall, thereby enabling the lifting of the mold and facilitating mold lifting and avoiding interference.

[0027] Both the top and bottom edges of the movable base 2 are hollowed out. An upper winch 8 is fixedly installed on both sides of the top edge of one movable base 2, and a lower winch 13 is fixedly installed on both sides of the bottom edge of the other movable base 2. The stranded wire wound inside the lower winch 13 and the upper winch 8 passes through the adjacent hollowed-out area on the side of one movable base 2 and intersects the hollowed-out area at the same height on the other movable base 2. After the mold is lifted, to prevent the two movable bases 2 from tilting inwards and moving closer together due to the weight of the mold, such as... Figure 1 As shown, the strands wound on the upper winch 8 and lower winch 13 on the left movable seat 2 pass through the hollowed-out area at the same height on the right movable seat 2 and are tied tightly. Then, the upper winch 8 and lower winch 13 are used to wind up the strands, which tightens the strands and generates a pulling force on the two movable seats 2, forcing the two movable seats 2 to move closer to the mold and clamp the side of the mold. This achieves the relative fixation of the two movable frames and the mold during the transfer.

[0028] The method of using this utility model is as follows: The sliding seat 1 is set on both sides of the mold to be transferred. The sliding seat 1 is fixed to the ground with bolts. At this time, the two moving seats 2 are far apart from each other, so that the mounting block 17 is misaligned with the mold. The motor 15 drives the reel 3 to rotate, and with the cooperation of the slot 14, the reel in the winding frame 9 rotates, so that the stranded wire wrapped on the surface is released. This makes it convenient for the pin 10 to be threadedly connected to the positioning hole on the surface of the mold or inserted in the horizontal direction. The winding wire can be wound up by the reel to lift the mold to a position higher than the mounting block 17. The electric push rod 11 retracts and pulls the connecting bar 12 to drive the moving seat 2 to slide from the sliding seat 1 towards the mold until the mounting block 17 moves to the bottom of the mold. At this time, the mold is put down, and the mounting blocks 17 on both sides can be used to support the bottom sides of the mold. Then, the upper winch 8 and the lower winch 13 are used to fix the relative position of the two moving seats 2 with the mold, so that the mold can be transferred by pushing the sliding frame.

[0029] The wiring diagrams of the motor 15, hydraulic rod 7, and electric push rod 11 in this utility model are common knowledge in the field. Their working principles are known technologies. The appropriate model is selected according to actual use. Therefore, the control method and wiring layout of the motor 15, hydraulic rod 7, and electric push rod 11 will not be explained in detail.

[0030] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
