Description

Technical Field

[0001] This utility model relates to the field of insulator production technology, and more specifically, to a molding die for an insulator. Background Technology

[0002] Insulators are devices that can withstand voltage and mechanical stress, installed between conductors at different potentials or between conductors and grounding components. There are many types of insulators. Although the structure and shape of different types of insulators vary greatly, they are all composed of two main parts: insulating parts and connecting hardware. The formation of insulating parts requires the cooperation of molding molds for manufacturing.

[0003] A molding die for an insulator, disclosed in Chinese Patent Publication No. CN115816771B, includes an upper die and a lower die. The bottom surface of the upper die has an upper injection cavity, and the top surface of the lower die has a lower injection cavity. The insulator is engaged with the lower injection cavity. Vent holes are provided at both ends of the lower injection cavity. A frame-shaped air groove is provided on the top surface of the lower die, and the vent holes are connected to the air groove. Annular grooves are provided on both sides of the lower injection cavity, and an annular ring is engaged within the annular groove. An engagement block is provided at the top of the annular ring. Engaging grooves are provided at the front and rear of the upper injection cavity, and the positions of the engagement grooves correspond to the positions of the engagement blocks. The inner wall of the annular ring is in contact with the cast iron parts at the front and rear of the insulator.

[0004] The dimensions of the upper and lower molds in the above-mentioned device are already fixed. If it is necessary to produce insulators of different sizes and models, it is necessary to redesign suitable molds, which takes a lot of time and results in low production efficiency.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figures 1-7 This utility model provides a technical solution:

[0029] A molding die for an insulator includes guide posts 10. Four sets of guide posts 10 are slidably connected to template 1 and template 2. Template 1 and template 2 are each composed of two sets of strip plates. The front outer wall of template 1 and template 2 is provided with a groove 13. The groove 13 penetrates the inner wall of template 1 and template 2. Several sets of sliders 12 are movably connected to the inner wall of the groove 13. A mold 6 is fixedly installed between the outer walls of every two sets of sliders 12 on the left and right sides. An extrusion component 8 is installed between the inner wall of the groove 13 and the outer wall of the mold 6. A locking component 3 is installed on the rear side of template 1 and template 2. A limit component 5 is installed on the front side of template 1 and template 2. An injection pipe 9 is installed on the top of one set of molds 6. A pushing component 4 is installed on the top of template 1 and the bottom of template 2.

[0030] Furthermore, the extrusion assembly 8 includes a guide rod 83, which is fixed to the inner wall of the rear side of the slide 13. The front end of the guide rod 83 extends to the inlet of the front end of the slide 13. Several sets of sliders 12 are slidably connected to the guide rod 83. An extrusion plate 84 is slidably connected to the rear end of the guide rod 83. A second spring 81 is fixedly installed between the rear side of the extrusion plate 84 and the inner wall of the rear side of the slide 13. The second spring 81 is sleeved on the outside of the guide rod 83. The front side of the extrusion plate 84 is in close contact with the outer wall of the rear side of the mold 6. A handle 7 is fixedly installed on the outer wall of the rear side of the extrusion plate 84. The handle 7 is connected to the locking assembly 3.

[0031] When the number of molds 6 needs to be increased, first move the extrusion plate 84 to the rear end of the slide 13 using the handle 7, and lock the handle 7 using the locking component 3. Then, push the molds 6 to be added from the front end of the slide 13 into the mold 1 and mold 2 respectively. Then, block the entry end of the slide 13 using the limiting component 5. Finally, release the restriction of the extrusion plate 84 by the locking component 3, so that the spring 2 81 automatically pushes the extrusion plate 84 to press the mold 6 located at the rear end of the slide 13 tightly, so that multiple sets of molds 6 are tightly arranged together to form a large mold 6.

[0032] Furthermore, the locking component 3 includes a limiting hole 35, which is formed on the side wall of the handle 7. Mounting blocks 32 are fixedly installed on the rear outer walls of both template 1 and template 2. A limiting rod 34 is inserted into the side wall of the mounting block 32, and a handle 31 is fixedly installed on the right end of the limiting rod 34.

[0033] Hold the handle 31 and pull it to the right. When the upper limit hole 35 of the handle 7 moves to the position parallel to the limit rod 34, push the limit rod 34 into the limit hole 35 through the handle 31 to lock the handle 7.

[0034] Furthermore, a limiting plate 33 is fixedly installed on the outer wall of the front end of the limiting rod 34, and a spring 36 is fixedly installed between the outer wall of the right side of the limiting plate 33 and the outer wall of the left side of the mounting block 32. The spring 36 is sleeved on the outside of the limiting rod 34.

[0035] When the upper limit hole 35 of the grip 7 moves to a position parallel to the limit rod 34, after releasing the grip 7, the spring 36 will automatically push the limit rod 34 through the limit plate 33 to insert it into the limit hole 35.

[0036] Furthermore, the limiting component 5 includes a rotating shaft 51, which is fixed to the front outer wall of template 1 and template 2 near the entry end of the slide 13. A baffle 52 is rotatably connected to the outer wall of the rotating shaft 51. A stop block 53 is fixedly installed at the right end of the front outer wall of template 1 and template 2. The stop block 53 is L-shaped, and the baffle 52 and the stop block 53 are plugged into each other.

[0037] When it is necessary to add mold 6, rotate baffle 52 to move it away from inside stop block 53. After adding mold 6, rotate baffle 52 back into stop block 53 to limit the outside of the inlet end of slide groove 13 and prevent mold 6 from moving out of slide groove 13.

[0038] Furthermore, the pushing component 4 includes a mounting bracket 42. Two sets of mounting brackets 42 are fixed to the top of template 1 and the bottom of template 2, respectively. Cylinders 41 are fixedly installed on the top and bottom of both sets of mounting brackets 42. The top of the cylinders 41 is fixed to an external object. The overlap and separation of template 1 and template 2 can be controlled by the extension and retraction of the cylinders 41.

[0039] Furthermore, a control device 11 is fixedly installed on the outer wall of template 1. The control device 11 is electrically connected to the cylinder 41. The control device 11 is a PLC controller used to control the operation of the cylinder 41.

[0040] Working principle: First, the extrusion assembly 8 is moved to the rear side of the slide 13. Then, the extrusion assembly 8 is locked by the locking assembly 3. Then, the limiting assembly 5 is opened, and an appropriate amount of mold 6 is inserted into the mold plate 1 and mold plate 2 through the slide 13. Then, the limiting assembly 5 is closed to block the inlet end of the slide 13. Then, the locking assembly 3 is released from locking the extrusion assembly 8, so that the extrusion assembly 8 automatically squeezes each set of mold 6 tightly between the mold plate 1 and mold plate 2. Then, the pushing assembly 4 pushes the mold plate 1 and mold plate 2 closer to each other along the guide post 10 until the mold plate 1 and mold plate 2 are in contact. Finally, the material is injected into the mold 6 through the injection pipe 9.
