Description

Technical Field

[0001] This utility model is a balloon forming device, belonging to the field of balloon processing equipment. Background Technology

[0002] A balloon molding apparatus is a device used to manufacture balloons, primarily for use in the medical field. Through the combined action of stretching and blow molding, polymer tubing is stretched under high pressure and high temperature in a biaxial manner (longitudinal and radial) to conform to the shape of a mold, forming a balloon. The balloon molding apparatus mainly consists of a mold system, a clamping mechanism, an inflation mechanism, a heating and cooling system, and a control system.

[0003] In the prior art, the heating system of the balloon molding device is used to heat the preform or mold to bring the material to a suitable molding temperature. Common heating methods include resistance heating and electromagnetic heating. The cooling system is used to quickly cool and solidify the balloon after molding to ensure the size and shape stability of the balloon. This is generally achieved through water jackets or cooling fans. Since the balloon blow molding mold is made of metal, the cooling starts from the outside of the mold and the temperature reaches the inside of the mold groove slowly, which reduces the cooling and molding speed of the balloon and thus reduces the efficiency of balloon blow molding.

[0004] In summary, this utility model provides a balloon forming device to solve the above problems. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a balloon forming device to solve the problem mentioned in the background technology that the cooling temperature reaches the inside of the mold groove slowly, thereby reducing the balloon forming speed.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a balloon molding device, including a base plate, with fixed plates fixedly installed on both sides of the top of the base plate, electric push rods fixedly installed around the perimeter of the opposite side of the two fixed plates, a connecting plate being installed between the output ends of every four adjacent electric push rods, a mold being fixedly installed on the opposite side of the two connecting plates, a mold groove being opened on the opposite side of the two molds, a slot being fixedly opened at the top of the two mold grooves, the top of the two slots extending to the top of the mold, and a cooling pipe assembly being fixedly installed between the top and bottom of the two molds, the cooling pipe assembly cooling the mold by injecting circulating condensate into the internal space of the mold.

[0007] Furthermore, the mold groove is hemispherical in shape, and the groove opening is semi-cylindrical.

[0008] Furthermore, the cooling pipe assembly includes a condensate delivery chamber, which is located inside the mold. The inlet end of the condensate delivery chamber extends to the top of the mold, and the outlet end of the condensate delivery chamber extends to the bottom of the mold.

[0009] Furthermore, the top of the mold, located at the inlet end of the condensate conveying chamber, is connected to an inlet pipe, and the bottom of the mold, located at the outlet end of the condensate conveying chamber, is connected to an outlet pipe.

[0010] Furthermore, one end of the inlet pipe passes through the connecting plate, and one end of the outlet pipe passes through the connecting plate.

[0011] Furthermore, the conveying path of the condensate conveying chamber is "S" shaped, and the overall outline of the condensate conveying chamber is circular.

[0012] Furthermore, both the inlet pipe and the outlet pipe are fixedly connected to the connecting plate, and one end of each of the inlet pipe and the outlet pipe is connected to a telescopic flexible hose.

[0013] The beneficial effects of this utility model are:

[0014] By activating the heat exchanger connected by the internal telescopic hoses of the two cooling pipe groups, and connecting the telescopic hoses connected to the inlet pipe to the outlet of the external heat exchanger, and connecting the telescopic hoses connected to the outlet pipe to the inlet of the external heat exchanger, the condensate inside the delivery chamber can be circulated and pumped through the two telescopic hoses to continuously cool the mold. This cools the balloon inside the mold groove, accelerates the balloon molding speed, and effectively improves the efficiency of balloon blow molding.

[0015] The condensate delivery chamber has an "S" shaped delivery path and a circular overall outline, which allows the condensate delivery chamber to surround the mold groove, thereby achieving uniform heat exchange and effectively improving the uniformity of the cooling and forming of the balloon inside the mold groove, thus effectively improving the quality of balloon blow molding.

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] Please see Figures 1-4 This utility model provides a technical solution: a balloon forming device, including a base plate 1, with fixed plates 2 fixedly installed on both sides of the top of the base plate 1, and electric push rods 3 fixedly installed on all four sides of the opposite side of the two fixed plates 2. A connecting plate 4 is installed between the output ends of every four adjacent electric push rods 3. Each electric push rod 3 is connected to an external power source and is equipped with the same power control switch. A mold 5 is fixedly installed on the opposite side of the two connecting plates 4. A mold groove 6 is opened on the opposite side of the two molds 5. A slot 7 is fixedly opened on the top of the two mold grooves 6. The top of the two slots 7 extends to the top of the mold 5. A cooling pipe assembly 8 is fixedly installed between the top and bottom of the two molds 5. The cold mold 5 has an internal space, which serves as a condensate delivery chamber. The cooling pipe assembly 8 cools the mold 5 by injecting circulating condensate into the internal space of the mold 5, thereby cooling the balloon inside the mold groove 6.

[0024] Please see Figures 2-3 The mold groove 6 is hemispherical, and the groove opening 7 is semi-cylindrical. The two mold grooves 6 are spliced ​​together to form a balloon groove. After the two groove openings 7 are spliced ​​together, the end of the blowing pipe on which the balloon embryo is sleeved is clamped, thereby ensuring the airtightness of the balloon during the blow molding process. The cooling pipe assembly 8 includes a condensate conveying chamber 81. The condensate conveying chamber 81 is opened inside the mold 5. The liquid inlet end of the condensate conveying chamber 81 extends to the top of the mold 5, and the liquid outlet end of the condensate conveying chamber 81 extends to the bottom of the mold 5. The top of the mold 5 and the liquid inlet end of the condensate conveying chamber 81 are connected to the liquid inlet pipe 82, and the bottom of the mold 5 and the liquid outlet end of the condensate conveying chamber 81 are connected to the liquid outlet pipe 83.

[0025] Please see Figures 2-4One end of the liquid inlet pipe 82 passes through the connecting plate 4, and one end of the liquid outlet pipe 83 passes through the connecting plate 4. The liquid inlet pipe 82 is fixedly connected to the connecting plate 4, and the liquid outlet pipe 83 is fixedly connected to the connecting plate 4. The conveying path of the condensate conveying chamber 81 is "S" shaped, and the overall outline of the condensate conveying chamber 81 is circular, so that the condensate conveying chamber 81 can wrap around the mold groove 6, thereby achieving uniform heat exchange.

[0026] Please see Figures 2-4 Both the inlet pipe 82 and the outlet pipe 83 are fixedly connected to the connecting plate 4. One end of each of the inlet pipe 82 and the outlet pipe 83 is connected to a telescopic hose 84. The telescopic hose 84 connected to the inlet pipe 82 is connected to the outlet end of the external heat exchanger, and the telescopic hose 84 connected to the outlet pipe 83 is connected to the inlet end of the external heat exchanger. By starting the external heat exchanger, the condensate inside the condensate delivery chamber 81 can be circulated and pumped through the two telescopic hoses 84, which can continuously cool the mold 5, thereby cooling the spherical tube inside the mold groove 6 and accelerating the spherical tube forming speed. The telescopic hose 84 can be extended and retracted with the movement of the connecting plate 4 to ensure the normal delivery of condensate.

[0027] Detailed implementation method: By placing the end of the air blowing tube containing the balloon preform between the two slots 7, the balloon preform can be located between the two mold grooves 6. Activate each electric push rod 3 to push the two molds 5 to move in opposite directions. When the two molds 5 are in contact with each other, the two mold grooves 6 can be spliced ​​together, and the two slots 7 can be spliced ​​together to form a balloon groove. After the two slots 7 are spliced ​​together, the end of the air blowing tube containing the balloon preform is clamped, thereby ensuring the airtightness of the balloon blow molding process.

[0028] After blow molding is completed, the heat exchanger connected by the internal telescopic hoses 84 of the two cooling pipe groups 8 is activated. The telescopic hose 84 connected to the liquid inlet pipe 82 is connected to the liquid outlet of the external heat exchanger, and the telescopic hose 84 connected to the liquid outlet pipe 83 is connected to the liquid inlet of the external heat exchanger. By activating the external heat exchanger, the condensate inside the condensate delivery chamber 81 can be circulated and pumped through the two telescopic hoses 84, which can continuously cool the mold 5, thereby cooling the balloon inside the mold groove 6, accelerating the balloon forming speed, and effectively improving the balloon blow molding efficiency. The telescopic hoses 84 can be extended and retracted with the movement of the connecting plate 4 to ensure the normal delivery of condensate.

[0029] The condensate conveying cavity 81 has an "S" shaped conveying path and a circular overall outline, which allows the condensate conveying cavity 81 to surround the mold groove 6, thereby achieving uniform heat exchange and effectively improving the uniformity of the cooling and forming of the balloon inside the mold groove 6, thus effectively improving the quality of the balloon blow molding process.
