Abstract
Description
Technical Field
[0001] This utility model relates to the field of manufacturing technology, specifically to a vertical heating device. Background Technology
[0002] Intra-aortic balloon counterpulsation (IABP) involves inserting a balloon between the descending aorta and renal artery via femoral artery puncture. Driven and controlled by an intra-aortic balloon counterpulsation pump, the balloon inflates during diastole and deflates at the end of diastole, thereby increasing coronary perfusion and reducing cardiac workload. As a crucial component of the IABP balloon catheter, the balloon's performance directly determines the overall performance of the IABP balloon catheter.
[0003] During the fabrication of balloons, the tubing first needs to be preheated to alter the material properties of the section to be formed, which is beneficial for subsequent blow molding expansion. However, in existing technologies, the tubing is arranged horizontally during preheating, and the middle of the tubing will sag due to gravity during the heating process, resulting in deformation of the balloon after molding. Utility Model Content
[0004] The purpose of this invention is to provide a vertical heating device with small deformation and uniform heating.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a vertical heating device, including a housing, a heating mold is provided on the housing, the mold cavity of the heating mold is arranged in a vertical direction, and an upper clamp and a lower clamp are respectively provided above and below the heating mold.
[0006] Furthermore, the heating mold includes a left heating half-mold and a right heating half-mold. The left heating half-mold and the right heating half-mold are driven by a finger cylinder to dock to form a heating mold cavity or to separate. Heating rods and thermocouples are provided inside the left heating half-mold and the right heating half-mold.
[0007] Furthermore, a first through hole and a second through hole are provided along the length direction of the left heating half mold and the right heating half mold. The heating rod is fixed in the first through hole and the length of the heating rod is the same as the length of the first through hole. The thermocouple is fixed in the second through hole. Two heating rods are symmetrically arranged on both sides of the thermocouple.
[0008] Furthermore, left clamping blocks are provided on both the upper and lower surfaces of the left heating half-mold, and right clamping blocks are provided on both the upper and lower surfaces of the right heating half-mold. The left and right clamping blocks have the same structure, are mirror-symmetrical and staggered in the height direction, and have a V-shaped opening facing the right clamping block. The two V-shaped openings are connected to clamp the material tube.
[0009] Furthermore, when the heating half mold and the right heating half mold are joined, the center line of the clamping joint formed by the left clamping block and the right clamping block is on the same vertical line as the center line of the mold cavity of the heating mold.
[0010] Furthermore, the upper and lower clamps are clamping cylinders.
[0011] Furthermore, a vertical plate is fixed to the side of the chassis, extending upward and protruding above the chassis. The heating mold, upper clamp, and lower clamp are all mounted on the vertical plate.
[0012] Furthermore, a fixed cover is provided on the outside of the heating mold, and protective covers are provided on the outside of the upper and lower clamps. The fixed cover and the protective cover are provided with openings for the feed pipe to enter and exit.
[0013] Furthermore, the chassis is equipped with a power supply module, a mold temperature control module, and a time control module.
[0014] In the above scheme, by setting the mold cavity of the heating mold in a vertical direction, the heating method of the material tube is optimized to ensure that the material tube will not be affected by gravity during the heating and softening process, thus improving the deformation of the balloon after molding.

Detailed Implementation
[0020] like Figures 1-3As shown, a vertical heating device includes a housing 10, on which a heating mold 20 is mounted. The cavity of the heating mold 20 is arranged vertically, and an upper clamp 30 and a lower clamp 40 are respectively arranged above and below the heating mold 20. In use, the middle section of the balloon tube passes through the cavity of the heating mold 20, and the upper and lower ends of the tube are clamped by the upper clamp 30 and the lower clamp 40 respectively. By arranging the cavity of the heating mold 20 vertically, the heating method of the tube is optimized, ensuring that the tube will not sag due to gravity during the heating and softening process, thereby improving the deformation of the balloon after molding.
[0021] See Figure 3 , Figure 4 The heating mold 20 includes a left heating half mold 21 and a right heating half mold 22. The left heating half mold 21 and the right heating half mold 22 are driven by a finger cylinder to dock to form a heating mold cavity A or to separate, which facilitates the loading and unloading of the material tube. Heating rods 23 and thermocouples 24 are provided in the left heating half mold 21 and the right heating half mold 22. The heating rods 23 generate heat to heat the mold, and the thermocouples 24 measure the mold temperature in real time and accurately and feed it back to the control unit to ensure that the temperature of the mold cavity is suitable.
[0022] Preheating requires ensuring a consistent temperature along the entire length of the material tube to avoid localized overheating or underheating. A first through-hole and a second through-hole are provided along the length of the left heating half-mold 21 and the right heating half-mold 22. A heating rod 23 is fixed within the first through-hole, and its length matches the length of the first through-hole. A thermocouple 24 is fixed within the second through-hole. Two heating rods 23 are symmetrically arranged on either side of the thermocouple 24. The length of the heating rod 23 covers the length of the half-mold, and the symmetrical arrangement of two heating rods 23 on either side of the thermocouple 24 ensures that the temperature is equal at all locations along the entire length of the mold cavity, guaranteeing uniform heating of the material tube.
[0023] During the heating process, it is essential to ensure that the tube section within the mold cavity remains straight. To achieve this, left clamping blocks 25 are provided on both the upper and lower surfaces of the left heating half-mold 21, and right clamping blocks 26 are provided on both the upper and lower surfaces of the right heating half-mold 22. The left and right clamping blocks 25 and 26 have identical structures, are mirror-symmetrical, and are staggered in the height direction. The left clamping block 25 has a V-shaped opening facing the right clamping block 26, and the two V-shaped openings interlock to clamp the tube. The staggered height arrangement of the left and right clamping blocks 25 and 26 ensures that during mold closing, one clamping block is in the upper position and the other in the lower position, with the symmetrical V-shaped openings overlapping to secure the tube. Ideally, the lower surface of one clamping block 25 and the upper surface of the other clamping block 26 should slide in contact with each other to further improve the stability of the tube clamping.
[0024] To further ensure the uniformity of heating of the tube, when the heating half mold 21 and the right heating half mold 22 are connected, the center line of the clamping joint formed by the left clamping block 25 and the right clamping block 26 is on the same vertical line as the center line of the mold cavity of the heating mold 20. That is, the tube is not only in the vertical direction, but also in the center of the mold cavity, so that the tube is heated evenly at all positions, which improves the uniformity of subsequent blow molding expansion.
[0025] Furthermore, the upper clamp 30 and the lower clamp 40 are clamping cylinders that clamp the upper and lower ends of the material tube.
[0026] A vertical plate 11 is fixed to the side of the chassis 10. The vertical plate 11 extends upward and protrudes above the chassis 10. The heating mold 20, the upper clamp 30 and the lower clamp 40 are all set on the vertical plate 11. The vertical plate 11 provides sufficient vertical space for arranging components, which can reduce the volume and weight of the entire heating device and make operation convenient.
[0027] The heating mold 20 is equipped with a fixed cover 50, and the upper clamp 30 and lower clamp 40 are equipped with protective covers 60. The fixed cover 50 and the protective cover 60 are provided with inlets and outlets for the feed pipe. The fixed cover 50 and the protective cover 60 can prevent external impurities from entering the heating mold 20, the upper clamp 30 and the lower clamp 40, and can also prevent the heating mold 20, the upper clamp 30 and the lower clamp 40 from being damaged by impact.
[0028] Furthermore, the chassis 10 is equipped with a power supply module, a mold temperature control module, and a time control module. The temperature control module controls the temperature of the mold cavity, and the time control module controls the heating time, thereby ensuring the heating effect.
