Description

Technical Field

[0001] This utility model relates to the field of catheter forming, and in particular to a medical catheter tip forming device. Background Technology

[0002] Medical catheters generally refer to various tubing devices specifically designed for the medical field. These catheters are designed in a variety of different shapes and sizes according to different medical uses and body parts. They are widely used in clinical diagnosis, treatment and nursing processes, and can effectively deliver drugs, drain fluids or perform other medical procedures.

[0003] In daily work, it has been found that during the molding process of medical catheter tips, the molding mold is usually kept at a high operating temperature because the plastic material needs to be heated to a molten state for shaping. When the molding process is completed and the operator needs to remove the molded catheter from the mold, the excessively high surface temperature of the mold can be quickly transferred to the operator's fingers through heat conduction. This sudden high temperature contact can not only cause instantaneous burns to the operator's hands, but may also lead to cumulative heat damage during long-term operation, seriously affecting production safety and the operator's health. Utility Model Content

[0004] The purpose of this invention is to address the problem that in existing technologies, molding molds typically maintain high operating temperatures. When the molding process is completed and the operator needs to remove the molded catheter from the mold, the excessively high surface temperature of the mold can be rapidly transferred to the operator's fingers through heat conduction. This sudden high-temperature contact can not only cause instantaneous burns to the operator's hands but may also lead to cumulative heat damage during long-term operation, seriously affecting production safety and the operator's health. Therefore, this invention proposes a medical catheter tip molding device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a medical catheter end forming device, comprising a chamber, two chamber doors rotatably connected to the surface of the chamber, a base plate fixedly connected to the inner wall of the chamber, a first cylinder fixedly installed on the top of the base plate, a first sliding groove and a limiting groove formed on the surface of the base plate, a first mold fixedly installed on the piston end of the first cylinder, the bottom of the first mold slidably connected to the surface of the first sliding groove, a forming component formed at the end of the base plate near the limiting groove, and a cooling component formed on the top of the forming component;

[0006] The molding assembly includes a second mold, a mounting plate, and guide rods. The second mold is fixedly installed on the top of the base plate. A clamping groove is provided on the side of the second mold. The mounting plate is fixedly installed on the bottom of the base plate near the limiting groove. Four openings are provided on the surface of the second mold. There are four guide rods, and all the guide rods are slidably connected to the surface of the openings.

[0007] As a further embodiment of this utility model, two clamping plates are slidably connected to the surface of the clamping groove. The two clamping plates are arranged opposite to each other on both sides of the second mold. Each clamping plate is rotatably connected to a first connecting rod at its end. The end of the first connecting rod away from the clamping plate is rotatably connected to a first slider.

[0008] As a further embodiment of this utility model, a second cylinder is fixedly installed at the bottom of the mounting plate, and a receiving plate is fixedly installed at the piston end of the second cylinder. A second sliding groove is provided on both sides of the receiving plate, and the second sliding groove is slidably connected to the first slider.

[0009] As a further embodiment of this utility model, a first push plate is fixedly installed at one end of the guide rod, and a second push plate is fixedly installed at the other end. Two third push plates are symmetrically installed on the surface of the second push plate. A third sliding groove is opened on the surface of the third push plate. Corrugated pipes are fixedly installed at the connection between the first push plate and the second mold, and at the connection between the second push plate and the second mold.

[0010] As a further embodiment of this utility model, a third cylinder is fixedly installed at the bottom of the base plate, a receiving block is fixedly installed at the output end of the third cylinder, and a second slider is fixedly installed at both ends of the receiving block, with the second slider slidably connected to the third slide groove.

[0011] As a further embodiment of this utility model, the cooling assembly includes a first motor, a fixed column, and a second motor. The first motor is fixedly installed on the top of the chamber, and the fixed column is fixedly installed on the upper surface of the inner wall of the chamber. A second connecting rod is fixedly installed at the output end of the first motor. The second connecting rod is L-shaped and rotatably connected to the bottom of the fixed column. The second motor is located at the bottom of the second connecting rod, and a fan blade is fixedly installed at the output end of the second motor.

[0012] As a further embodiment of this utility model, a first fixing rod is fixedly installed on both sides of the fixing column, and a second fixing rod is rotatably connected to the end of the first fixing rod. A rotating shaft is fixedly installed on the top of the second motor, and the rotating shaft is rotatably connected to the end of the second connecting rod. The side of the second motor is rotatably connected to the surface of the second fixing rod.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] In this invention, a second motor drives the fan blades to rotate, thereby dissipating heat from the first and second molds. The first motor also drives the second connecting rod to rotate. Since the second connecting rod is L-shaped and limited by the first and second fixed rods, it causes the fan blades and the first motor to oscillate, resulting in more even heat dissipation. A second cylinder pushes the receiving plate, causing the first connecting rod to deflect under the sliding cooperation of the first slider and the second slide groove, bringing the two clamping plates closer together and clamping the end of the guide rod for easy demolding. Furthermore, a third cylinder pushes the receiving block, allowing the guide rod to slide along the opening direction of the second mold under the cooperation of the second slider and the third slide groove. This allows the first push plate to push the guide tube, enabling demolding and preventing safety hazards caused by manual operation. Attached Figure Description

[0021] Please see Figure 1-5This utility model provides a technical solution: a medical catheter end forming device, including a chamber 1, two chamber doors 2 rotatably connected to the surface of the chamber 1, a base plate 11 fixedly connected to the inner wall of the chamber 1, a first cylinder 3 fixedly installed on the top of the base plate 11, a first sliding groove 12 and a limiting groove 13 opened on the surface of the base plate 11, a first mold 31 fixedly installed on the piston end of the first cylinder 3, the bottom of the first mold 31 slidably connected to the surface of the first sliding groove 12, a forming component 4 opened at the end of the base plate 11 near the limiting groove 13, and a cooling component 5 provided on the top of the forming component 4.

[0022] In this embodiment: the molding component 4 includes a second mold 41, a mounting plate 42 and guide rods 44. The second mold 41 is fixedly installed on the top of the base plate 11. The second mold 41 has a clamping groove 43 on its side. The mounting plate 42 is fixedly installed on the bottom of the base plate 11 near the end of the limiting groove 13. The surface of the second mold 41 has four openings. There are four guide rods 44, and all the guide rods 44 are slidably connected to the surface of the openings.

[0023] To address the issue of manual removal by staff after catheter formation, please refer to [link / reference]. Figure 2-4 Two clamping plates 431 are slidably connected to the surface of the clamping groove 43. The two clamping plates 431 are arranged on both sides of the second mold 41. The ends of the clamping plates 431 are rotatably connected to the first connecting rods 432. The end of the first connecting rods 432 away from the clamping plates 431 is rotatably connected to the first slider 433.

[0024] A second cylinder 421 is fixedly installed at the bottom of the mounting plate 42. A receiving plate 422 is fixedly installed at the piston end of the second cylinder 421. A second sliding groove 423 is provided on both sides of the receiving plate 422. The second sliding groove 423 is slidably connected to the first slider 433. Driving the second cylinder 421 can push the receiving plate 422. The first connecting rod 432 will deflect under the sliding cooperation between the first slider 433 and the second sliding groove 423, thereby bringing the two clamping plates 431 closer together, thereby clamping the end of the guide rod 44 for easy demolding.

[0025] A first push plate 441 is fixedly installed at one end of the guide rod 44, and a second push plate 442 is fixedly installed at the other end. Two third push plates 443 are symmetrically installed on the surface of the second push plate 442. A third slide groove 444 is opened on the surface of the third push plate 443. A corrugated pipe 45 is fixedly installed at the connection between the first push plate 441 and the second mold 41, and at the connection between the second push plate 442 and the second mold 41. The model of the corrugated pipe 45 is MED-PP-BW50-S. The corrugated pipe 45 can assist the entry of the conduit material.

[0026] A third cylinder 46 is fixedly installed at the bottom of the base plate 11. A receiving block 461 is fixedly installed at the output end of the third cylinder 46. A second slider 462 is fixedly installed at both ends of the receiving block 461. The second slider 462 is slidably connected to the third slide groove 444. The third cylinder 46 can push the receiving block 461. With the cooperation of the second slider 462 and the third slide groove 444, the guide rod 44 can slide along the opening direction of the second mold 41, so that the first push plate 441 can push the guide tube to demold it, preventing the user from operating it by hand and causing safety hazards.

[0027] To resolve the issue of excessively high catheter temperature, please refer to [link / reference]. Figure 5 The cooling assembly 5 includes a first motor 51, a fixed column 52, and a second motor 54. The first motor 51 is fixedly installed on the top of the chamber 1. The fixed column 52 is fixedly installed on the upper surface of the inner wall of the chamber 1. A second connecting rod 53 is fixedly installed at the output end of the first motor 51. The second connecting rod 53 is L-shaped and rotatably connected to the bottom of the fixed column 52. The second motor 54 is located at the bottom of the second connecting rod 53. A fan blade 542 is fixedly installed at the output end of the second motor 54. Driving the second motor 54 can drive the fan blade 542 to rotate, thereby dissipating heat from the first mold 31 and the second mold 41.

[0028] First fixing rods 521 are fixedly installed on both sides of the fixing column 52. Second fixing rods 522 are rotatably connected to the ends of the first fixing rods 521. A rotating shaft 541 is fixedly installed on the top of the second motor 54. The rotating shaft 541 is rotatably connected to the end of the second connecting rod 53. The side of the second motor 54 is rotatably connected to the surface of the second fixing rod 522. The first motor 51 can drive the second connecting rod 53 to rotate. Since the second connecting rod 53 is L-shaped, and under the limitation of the first fixing rod 521 and the second fixing rod 522, the second connecting rod 53 will drive the fan blade 542 and the first motor 51 to swing, thereby making the heat dissipation more uniform.

[0029] Working principle: Raw material is fed into the conduit of the second push plate 442. The raw material enters the second mold 41 and the first mold 31 through the corrugated pipe 45 for molding. When demolding is required, the second motor 54 drives the fan blade 542 to rotate, thereby dissipating heat from the first mold 31 and the second mold 41. Furthermore, the first motor 51 drives the second connecting rod 53 to rotate. Since the second connecting rod 53 is L-shaped and limited by the first fixed rod 521 and the second fixed rod 522, the second connecting rod 53 will drive the fan blade 542 and the first mold 31 to rotate. A motor 51 oscillates, thus making heat dissipation more even; the second cylinder 421 drives the receiving plate 422, wherein the first connecting rod 432 deflects under the sliding cooperation of the first slider 433 and the second slide groove 423, thereby bringing the two clamping plates 431 closer together and clamping the end of the guide rod 44; then the third cylinder 46 pushes the receiving block 461, and under the cooperation of the second slider 462 and the third slide groove 444, the guide rod 44 can slide along the opening direction of the second mold 41, so that the first push plate 441 can push the guide tube and demold it.

[0030] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
