Description

Technical Field

[0001] This invention relates to the field of wire drawing machine technology, specifically to a die assembly for a wire drawing machine. Background Technology

[0002] In the process of processing yarn, the raw materials need to be transported to the injection molding machine. After the raw materials are heated to a molten state by the injection molding machine, they are injected into the mold assembly and extruded to form a film. The film is cooled in cooling water and then cut into filaments, which are finally woven on a circular loom.

[0003] In the prior art, patent number CN208247405U, entitled "A Die Assembly for a Wire Drawing Machine," includes an upper die and a lower die, with a cavity provided between the upper die and the lower die. An adjusting block is integrally connected to the upper die, and an extrusion gap communicating with the cavity is formed between the adjusting block and the lower die. An adjusting mechanism is provided on one side of the adjusting block to drive the adjusting block closer to or further away from the lower die, which has the effect of preventing burrs from being generated in the die assembly and causing damage to the extruded film.

[0004] However, existing wire drawing machines require manual pulling of the film into cooling water after extrusion. Since personnel are in direct contact with the surface of the film, the film temperature is high, and manual movement of the film can cause wrinkles and deformation. Summary of the Invention

[0005] The purpose of this invention is to provide a die assembly for a wire drawing machine to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a die assembly for a wire drawing machine, comprising: A limiting plate has a first fixing ring and a second fixing ring fixed on its surface.

The film passes between the first clamping plate and the second clamping plate, squeezing the first and second clamping plates, causing the spring to be compressed and retract into the groove. The clamping strips on the surfaces of the first and second clamping plates clamp the film. By directly moving the first and second clamping plates, the film can be transferred without causing wrinkles. Attached Figure Description

The insertion rods 19 on the surface of one set of the first clamping plate 17 and the second clamping plate 20 can be inserted into the arc plate 18 on the surface of the other set of the first clamping plate 17 and the second clamping plate 20, so that the two sets of the first clamping plate 17 and the second clamping plate 20 can be combined, making it easier to remove the first clamping plate 17 and the second clamping plate 20 from the film surface and place them on the top of the support plate 16.

[0028] Example 2: Based on Example 1, the first fixing ring 14 and the second fixing ring 15 are connected to the side plate 3. An upper mold body 1 and a lower mold body 2 are provided on one side of the side plate 3. A heat insulation plate 5 is provided on the surface of the upper mold body 1 and the lower mold body 2. A wiring cover 6 and a lifting column 7 are provided on the top of the upper mold body 1 and the lower mold body 2. An aviation socket 8 is also provided on the top of the upper mold body 1 and the lower mold body 2. The first fixing ring 14 and the second fixing ring 15 are fixed to the surface of the side plate 3 by screws. 14 and the second fixing ring 15 are located on both sides of the side plate 3. The limiting plate 13 is located at the bottom of the upper mold body 1 and the lower mold body 2. An opening is provided between the upper mold body 1 and the hook-type fine adjustment rod 4. The limiting plate 13 is located at the bottom of the opening. A hole is opened on the surface of the support plate 16. The stabilizing rod 25 can be inserted into the hole on the surface of the support plate 16, so that the upright 21 is located at the top of the support plate 16. The center rod 23 is located between the upright 21 and the stabilizing rod 25. The diameter of the center rod 23 is smaller than that of the stabilizing rod 25. The diameter of the upright 21 is the same. The first clamping plate 17 and the second clamping plate 20 are sleeved on the surface of the central rod 23. The first clamping plate 17 and the second clamping plate 20 can move up and down outside the central rod 23. The surfaces of the first clamping plate 17 and the second clamping plate 20 are provided with grooves 24. One end of the spring 22 is connected to the groove 24 on the surface of the first clamping plate 17, and the other end of the spring 22 is connected to the groove 24 on the surface of the second clamping plate 20. The spring 22 has a pushing force on the first clamping plate 17 and the second clamping plate 20, so that the first clamping plate 17 and the second clamping plate 20 move away from each other. Two sets of arc plates 18 are fixed at the middle position of the first clamping plate 17 and the second clamping plate 20. The surface of one set of arc plates 18 is fixed with a plug rod 19, and the surface of the other set of arc plates 18 is provided with a round hole.

The film extruded between the hook-type fine adjustment rods 4 and the upper mold body 1 passes between the first clamping plate 17 and the second clamping plate 20. After the first clamping plate 17 and the second clamping plate 20 approach each other, the clamping strips 26 on the surfaces of the first clamping plate 17 and the second clamping plate 20 can clamp the surface of the film. When the holding plates 20 come close to each other, the spring 22 is compressed and can retract into the groove 24. A stabilizing rod 25 is inserted into the support plate 16. The film passes between the first clamping plate 17 and the second clamping plate 20, and the first clamping plate 17 and the second clamping plate 20 are compressed, so that the spring 22 is compressed and can retract into the groove 24. The clamping strips 26 on the surface of the first clamping plate 17 and the second clamping plate 20 clamp the film.

After the film exits, it moves according to the limitation of the limiting plate 13. A stabilizing rod 25 is inserted into the support plate 16. The film passes between the first clamping plate 17 and the second clamping plate 20. By squeezing the first clamping plate 17 and the second clamping plate 20, the spring 22 is compressed and can retract into the groove 24. The clamping strips 26 on the surface of the first clamping plate 17 and the second clamping plate 20 clamp the film. The film can be transferred by directly moving the first clamping plate 17 and the second clamping plate 20 without causing wrinkles. The first clamping plate 17 and the second clamping plate 20 are provided in two sets. The insertion rods 19 on the surface of one set of the first clamping plate 17 and the second clamping plate 20 can be inserted into the arc plate 18 on the surface of the other set of the first clamping plate 17 and the second clamping plate 20, so that the two sets of the first clamping plate 17 and the second clamping plate 20 can be combined, making it easy to remove the first clamping plate 17 and the second clamping plate 20 from the film surface and place them on the top of the support plate 16.
