Description

Technical Field

[0001] This invention belongs to the field of mold technology, and specifically relates to an energy-saving mold for producing cold shrink cable accessories. Background Technology

[0002] Cold-shrink cable accessories are key components for the insulation and sealing protection of power transmission line joints. The industry mainstream adopts a high-temperature vulcanization molding process using liquid silicone rubber. The heat insulation capacity and heat loss of the molding die directly determine the power consumption of the production line and the overall production cost of the product.

[0003] Commercially available simple translation molds do not have integrated self-locking components. After the lower mold separates from the upper mold, when the part is taken out from the top of the lower mold, the lower mold is prone to shaking and shifting. At this time, the gap between the lower mold and the upper mold increases, and a large amount of internal heat is leaked out from the gap.

[0004] Therefore, it is necessary to invent an energy-saving mold for producing cold-shrink cable accessories to solve the above problems. Summary of the Invention

[0005] To address the aforementioned problems, this invention provides an energy-saving mold for producing cold-shrink cable accessories, thereby solving the issues raised in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an energy-saving mold for producing cold-shrink cable accessories, comprising: an upper mold plate and a lower mold plate, each having a built-in forming cavity for holding a heating rod; a material passage pipe installed on the front side of the lower mold plate for introducing material into the forming cavity; an upper heating plate and a lower heating plate respectively installed on the top of the upper mold plate and the bottom of the lower mold plate for conducting heat to the upper and lower mold plates; a driving component located at the bottom of the lower heating plate for driving the lower mold plate to pressurize the upper mold plate; and a lifting plate located at the output end of the driving component, with the lower heating plate mounted on the top of the lifting plate using a sliding component.

[0007] Furthermore, the upper heating plate is installed at the bottom of the top plate, the driving component is installed at the top of the bottom plate, the top surface of the bottom plate is penetrated by a vertical rod, and fastening sleeves are provided at both the top and bottom of the top plate, with the fastening sleeves spirally sleeved on the surface of the vertical rod.

[0008] Furthermore, the top and bottom of both the upper and lower heating plates are provided with support plates, and the upper template is connected to the upper heating plate using the support plates, and the lower template is connected to the lower heating plate using the support plates.

[0009] Furthermore, the sliding component includes: a sliding plate and a crossbar; two horizontally arranged crossbars are fixed to the top of the lifting plate, the two crossbars are arranged in parallel, the outer circumference of the crossbars does not contact the surface of the lifting plate, the sliding plate is slidably sleeved on the surface of the crossbars by means of a sliding groove, and the lower heating plate is fixed to the top surface of the sliding plate by means of a frame plate.

[0010] Furthermore, a protruding plate is fixed to the front end of the crossbar, and a bottom groove corresponding to the protruding plate is opened on the front side of the slide plate. The bottom groove is located in the front part of the slide groove, and an insert rod that penetrates the protruding plate is fixed inside the bottom groove.

[0011] Furthermore, the surface of the convex plate is provided with an insertion hole, and the length of the insertion rod is greater than the width of the convex plate.

[0012] Furthermore, the front end of the crossbar is locked with a locking member, which includes a folding plate, a pressure rod, a limiting rod, a wedge, and an elastic element. The front side of the convex plate is provided with a folding plate, and a limiting rod is fixed to the front side of the convex plate. A groove is provided at the center of the folding plate. The folding plate is sleeved on the surface of the limiting rod through the groove. The top of the folding plate is rotatably sleeved on the front end of the pressure rod. The rear end of the pressure rod uses a chamfered surface to press the inclined surface of the wedge. The elastic force of the elastic element makes the inclined surface of the wedge fit against the chamfered surface of the pressure rod.

[0013] Furthermore, a side plate is fixed to the top of the wedge block, and an inner rod is provided inside the pressure rod that penetrates the side plate. The bottom surface of the side plate is connected to the inside of the pressure rod by an elastic element.

[0014] The technical effects and advantages of this invention are as follows: 1. This invention uses an upper heating plate, a lower heating plate, and a heating rod to control the temperature in a coordinated manner, resulting in a uniform temperature distribution inside the molding cavity. The vertical rod and the double-layer fastening sleeve lock the top plate and the upper template. The double parallel suspended horizontal rods ensure that the slide plate will not tilt during the translation process, avoiding tilted gaps between the upper and lower templates. The driving component ensures that the upper and lower templates are in a tight mold-closing state, reducing heat leakage from gaps and reducing heat loss.

[0015] 2. The present invention uses the weight of the frame plate, the lower heating plate and the slide plate to make the insertion rod pass through the insertion hole of the protruding plate. Under the rotation of the folding plate, the pressure rod squeezes the wedge block. The wedge block and the slide groove cooperate to limit the slide plate, so as to prevent the lower template from shifting or shaking during the process of collecting the original parts. Pressing the bottom of the front side of the folding plate makes it easy to quickly unlock the wedge block and push the slide plate back to the bottom of the upper template.

[0017] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0018] This invention provides an energy-saving mold for producing cold-shrink cable accessories, such as... Figure 1 As shown, it includes: upper template 1, lower template 2, material passage pipe 3, upper heating plate 4, lower heating plate 5, driving component 6, lifting plate 7, top plate 8, bottom plate 9, vertical rod 10 and fastening sleeve 11. The driving component 6 is set as a driving cylinder. The bottom plate 9 is placed horizontally on the ground. Vertical rods 10 are fixed on the top surfaces of both ends of the bottom plate 9. The vertical rods 10 vertically penetrate the top plate 8. Fastening sleeves 11 are provided at the top and bottom of the top plate 8. The fastening sleeves 11 are spirally sleeved on the surface of the vertical rods 10. At this time, the top plate 8 is horizontally located at the top of the bottom plate 9.

[0019] The upper heating plate 4 and the lower heating plate 5 are both equipped with support plates at their top and bottom. The upper heating plate 4 is connected to the bottom surface of the top plate 8 via the support plates, and the lower heating plate 5 is connected to the top surface of the lifting plate 7 via the support plates. The upper template 1 is connected to the upper heating plate 4 via the support plates, and the lower template 2 is connected to the lower heating plate 5 via the support plates. The driving component 6 is installed on the top of the base plate 9, and the lifting plate 7 is driven and installed at the output end of the driving component 6. The end of the lifting plate 7 is slidably sleeved on the surface of the vertical rod 10. Both the upper heating plate 4 and the lower heating plate 5 have built-in heating wires, and the heat generated by the heating wires is conducted to the upper template 1 and the lower template 2, respectively.

[0020] Both the bottom surface of the upper mold 1 and the top surface of the lower mold 2 are provided with molding cavities. The rear end of the heating rod 101 is located inside the molding cavity, and the front end of the heating rod 101 is externally connected to a power supply and controller for heating the material inside the molding cavity. The front side of the lower mold 2 is provided with a material passage pipe 3, through which the material is introduced into the molding cavity. The material is set as liquid silicone rubber.

[0021] The upper template 1 and the lower template 2 have built-in forming cavities for holding the heating rod 101; the material passage pipe 3 is installed on the front side of the lower template 2 for feeding material into the forming cavity; the upper heating plate 4 and the lower heating plate 5 are respectively installed on the top of the upper template 1 and the bottom of the lower template 2 for conducting heat to the upper template 1 and the lower template 2; the driving component 6 is located at the bottom of the lower heating plate 5 for driving the lower template 2 to pressurize the upper template 1; the lifting plate 7 is located at the output end of the driving component 6, and the lower heating plate 5 is installed on the top of the lifting plate 7 by means of a sliding component.

[0022] Specifically, two heating rods 101 are placed on top of the lower mold plate 2, with the rear ends of the heating rods 101 inside the molding cavity of the lower mold plate 2. The drive unit 6 is activated, and the lifting plate 7 at the output end of the drive unit 6 moves up on the surface of the vertical rod 10. The lifting plate 7 uses the lower heating plate 5 to drive the lower mold plate 2 to move up synchronously. At this time, the lower mold plate 2 brings the heating rods 101 closer to the upper mold plate 1. Since both fastening sleeves 11 are limited by the top plate 8 through the vertical rod 10, the top plate 8 uses the frame plate to limit the upper heating plate 4 and the upper mold plate 1 until the upper mold plate 1 and the lower mold plate 2 are in the mold closing state. The upper mold plate 1 and the lower mold plate 2 cooperate to clamp the heating rods 101. At this time, the molding cavity is wrapped around the outside of the heating rods 101, and the heating rods 101 are set as mandrels.

[0023] The controller activates the heating rod 101, and the heat generated by the heating wire is conducted to the upper mold plate 1 and the lower mold plate 2, bringing the molding cavity to the vulcanization temperature. The molding raw material is refined to form liquid silicone rubber, which is then introduced into the molding cavity through the feed pipe 3. The material undergoes vulcanization at the vulcanization temperature, and is then molded inside the molding cavity to form a component. This component is then wrapped around the rear end of the heating rod 101.

[0024] After vulcanization, the lifting plate 7 at the output end of the drive component 6 moves down on the surface of the vertical rod 10. The top plate 8 uses the frame plate to limit the upper heating plate 4 and the upper template 1. The lifting plate 7 uses the lower heating plate 5 to drive the lower template 2 to move down synchronously. The upper template 1 separates from the lower template 2. At this time, the original part and the heating rod 101 move down synchronously with the lower template 2. When the heating rod 101 is removed from the molding cavity of the lower template 2, the flash, sprue and other waste materials of the original part are cut off. The original part is processed by manual trimming, and the waste materials are collected and recycled. After the original part is separated from the heating rod 101, the heating rod 101 is placed back on the top of the lower template 2, completing the molding process of the cold shrink cable accessory.

[0025] In this embodiment, the upper heating plate 4, the lower heating plate 5 and the heating rod 101 work together to control the temperature, resulting in a uniform temperature distribution inside the molding cavity. The vertical rod 10 and the double-layer fastening sleeve 11 lock the top plate 8 and the upper template 1. The driving component 6 ensures that the upper template 1 and the lower template 2 are in a tight mold-closing state, reducing heat leakage from gaps and lowering heat loss.

[0026] To quickly remove the original part from inside the molding cavity, a sliding component is used to create a misalignment and separation between the upper mold plate 1 and the lower mold plate 2. Figures 1 to 3 In this system, the sliding components include a sliding plate 12 and a crossbar 13. Two horizontally arranged crossbars 13 are fixed to the top of the lifting plate 7. The two crossbars 13 are parallel to each other, and their outer circumferences do not contact the surface of the lifting plate 7. The sliding plate 12 is slidably fitted onto the surface of the crossbars 13 via a sliding groove 121, and the lower heating plate 5 is fixed to the top surface of the sliding plate 12 via a frame plate. A protruding plate 14 is fixed to the front end of the crossbar 13, and a bottom groove 122 corresponding to the protruding plate 14 is opened on the front side of the sliding plate 122, which is located in front of the sliding groove 121.

[0027] Specifically, the lifting plate 7 uses the lower heating plate 5 to drive the lower template 2 to move down synchronously. After the upper template 1 separates from the lower template 2, the driving component 6 stops working. The sliding plate 12 is pulled, and the sliding plate 12 moves forward on the surface of the crossbar 13 using the sliding groove 121. The moving sliding plate 12 causes the bottom groove 122 to gradually approach the convex plate 14. The moving sliding plate 12 uses the frame plate to drive the lower heating plate 5 and the lower template 2. At this time, the lower template 2 and the upper template 1 move out of alignment. The lower template 2 uses the heating rod 101 to drive the molded part to move forward synchronously until the sliding plate 12 uses the bottom groove 122 to lock onto the outside of the convex plate 14. The moving sliding plate 12 stops, making it convenient to remove the molded part from the molding cavity of the lower template 2.

[0028] After the molded part is removed, the slide plate 12 is pushed in the opposite direction. The slide plate 12 gradually moves away from the convex plate 14 until the rear end of the crossbar 13 limits the slide plate 12. At this time, the molding cavity of the lower template 2 corresponds to the molding cavity of the upper template 1, so that the upper template 1 and the lower template 2 can continue to process the molded part using the molding cavity.

[0029] In this embodiment, the double parallel suspended crossbars 13 ensure that the slide plate 12 will not tilt during the translation process, and avoid tilting gaps between the upper template 1 and the lower template 2. At this time, the bottom groove 122 and the convex plate 14 can realize the rapid positioning of the slide plate 12.

[0030] To ensure the stability of the lower template 2 during the collection of the original parts, the sliding plate 12 is locked using a locking mechanism. Figures 1 to 4In this design, the locking components include: a folding plate 16, a pressure rod 17, a limiting rod 18, a wedge 19, and an elastic element 20, wherein the elastic element 20 is configured as a spring sheet; the surface of the convex plate 14 is provided with an insertion hole 141, and an insertion rod 15 penetrating the convex plate 14 is fixed inside the bottom groove 122, the length of the insertion rod 15 being greater than the width of the convex plate 14. The folding plate 16 is provided on the front side of the convex plate 14, and the limiting rod 18 is fixed on the front side of the convex plate 14. A groove 161 is provided at the center of the folding plate 16, and the folding plate 16 is sleeved on the surface of the limiting rod 18 using the groove 161. The top end of the folding plate 16 is rotatably sleeved on the front end of the pressure rod 17, and the rear end of the pressure rod 17 uses a chamfered surface to press the inclined surface 191 of the wedge 19. The elastic force of the elastic element 20 causes the inclined surface 191 of the wedge 19 to fit against the chamfered surface of the pressure rod 17.

[0031] A side plate is fixed to the top of the wedge block 19, and an inner rod 21 that penetrates the side plate is provided inside the pressure rod 17. The bottom surface of the side plate is connected to the inside of the pressure rod 17 by an elastic element 20.

[0032] Specifically, the slide plate 12 is moved forward on the surface of the crossbar 13 by pulling. When the slide plate 12 covers the outside of the convex plate 14 through the bottom groove 122, the frame plate, the lower heating plate 5 and the slide plate 12 use their own weight to make the insertion rod 15 pass through the insertion hole 141 of the convex plate 14, and the front end of the insertion rod 15 presses the bottom of the rear side of the folding plate 16.

[0033] The compression of the insert rod 15 causes the folding plate 16 to rotate. The folding plate 16 rotates on the surface of the limiting rod 18 using the groove 161. The top of the rotating folding plate 16 pushes the pressure rod 17 backward. At this time, the folding plate 16 slides on the surface of the limiting rod 18 using the groove 161. The rear end of the pressure rod 17 moves backward inside the crossbar 13. The backward-moving pressure rod 17 uses the chamfered surface to press the inclined surface 191 of the wedge block 19. The pressure of the chamfered surface causes the wedge block 19 to move downward. During the downward movement, the wedge block 19 uses the side plate to press the elastic element 20, and the inner rod 21 makes the wedge block 19 and the side plate move downward stably until the bottom of the wedge block 19 moves out of the crossbar 13. At this time, the wedge block 19 cooperates with the inner wall of the pressing groove 121 to complete the limitation of the slide plate 12, so as to prevent the lower template 2 from shifting or shaking during the process of collecting the original parts.

[0034] After the original is collected, press the bottom of the front side of the folding plate 16. The folding plate 16 cooperates with the front end of the pull rod 17. At this time, the pull rod 17 cannot restrict the wedge block 19. The elastic force of the elastic element 20 causes the wedge block 19 to enter the interior of the crossbar 13. At this time, the wedge block 19 cannot restrict the slide plate 12, making it easy to push the slide plate 12 back to the lower part of the upper template 1. At this time, the upper template 1 corresponds to the lower template 2.

[0035] In this embodiment, the weight of the frame plate, the lower heating plate 5 and the slide plate 12 causes the insertion rod 15 to pass through the insertion hole 141 of the protruding plate 14. Under the rotation of the folding plate 16, the pressure rod 17 presses the wedge block 19. The wedge block 19 cooperates with the slide groove 121 to limit the slide plate 12, so as to prevent the lower template 2 from shifting or shaking during the process of collecting the original parts. Pressing the bottom of the front side of the folding plate 16 makes it easy to quickly unlock the wedge block 19 and push the slide plate 12 back to the bottom of the upper template 1.

[0036] Working principle of this invention: Reference Figures 1 to 4 As shown, two heating rods 101 are placed on top of the lower mold plate 2, with the rear ends of the heating rods 101 inside the molding cavity of the lower mold plate 2. The drive unit 6 is activated, and the lifting plate 7 at the output end of the drive unit 6 moves up on the surface of the vertical rod 10. The lifting plate 7 uses the lower heating plate 5 to drive the lower mold plate 2 to move up synchronously. At this time, the lower mold plate 2 brings the heating rods 101 closer to the upper mold plate 1. Since both fastening sleeves 11 limit the top plate 8 through the vertical rod 10, the top plate 8 uses the frame plate to limit the upper heating plate 4 and the upper mold plate 1 until the upper mold plate 1 and the lower mold plate 2 are in the mold closing state. The upper mold plate 1 and the lower mold plate 2 cooperate to clamp the heating rods 101, and at this time the molding cavity is wrapped around the outside of the heating rods 101.

[0037] The controller puts the heating rod 101 into working state, and the heat generated by the heating wire is conducted to the upper template 1 and the lower template 2 respectively. The material is introduced into the molding cavity through the material pipe 3. The material completes vulcanization at the vulcanization temperature. At this time, the material is formed inside the molding cavity to form the original part. The original part is wrapped around the rear end of the heating rod 101.

[0038] After vulcanization, the lifting plate 7 at the output end of the drive component 6 moves down on the surface of the vertical rod 10. The top plate 8 uses the frame plate to limit the upper heating plate 4 and the upper template 1. The lifting plate 7 uses the lower heating plate 5 to drive the lower template 2 to move down synchronously. The upper template 1 and the lower template 2 separate. At this time, the original part and the heating rod 101 move down synchronously with the lower template 2. The slide plate 12 moves forward on the surface of the crossbar 13 by pulling. When the slide plate 12 covers the outside of the convex plate 14 through the bottom groove 122, the frame plate, the lower heating plate 5 and the slide plate 12 use their own weight to make the insertion rod 15 pass through the insertion hole 141 of the convex plate 14, and the front end of the insertion rod 15 presses the bottom of the rear side of the folded plate 16.

[0039] The compression of the insert rod 15 causes the folding plate 16 to rotate. The folding plate 16 rotates on the surface of the limiting rod 18 using the groove 161. The top of the rotating folding plate 16 pushes the pressure rod 17 backward. At this time, the folding plate 16 slides on the surface of the limiting rod 18 using the groove 161. The rear end of the pressure rod 17 moves backward inside the crossbar 13. The backward-moving pressure rod 17 uses the chamfered surface to press the inclined surface 191 of the wedge block 19. The pressure of the chamfered surface causes the wedge block 19 to move downward. During the downward movement, the wedge block 19 uses the side plate to press the elastic element 20, and the inner rod 21 makes the wedge block 19 and the side plate move downward stably until the bottom of the wedge block 19 moves out of the crossbar 13. At this time, the wedge block 19 cooperates with the inner wall of the pressing groove 121 to complete the limitation of the slide plate 12, so as to prevent the lower template 2 from shifting or shaking during the process of collecting the original parts.

[0040] When the heating rod 101 is removed from the molding cavity of the lower mold plate 2, the flash, sprue, and other waste materials of the original sprue are cut off. The original sprue is processed by manual trimming, and the waste materials are collected and recycled. After the original sprue is separated from the heating rod 101, the heating rod 101 is placed back on top of the lower mold plate 2. Press down the bottom of the front side of the folding plate 16. The folding plate 16 cooperates with the front end of the pressure rod 17. At this time, the pressure rod 17 cannot restrain the wedge 19. The elastic force of the elastic element 20 causes the wedge 19 to enter the interior of the crossbar 13. At this time, the wedge 19 cannot restrain the slide plate 12, making it easy to push the slide plate 12 back to the lower part of the upper mold plate 1. At this time, the upper mold plate 1 and the lower mold plate 2 correspond, making it easy for the upper mold plate 1 and the lower mold plate 2 to continue to process the molded part using the molding cavity.

[0041] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it.
