A cooling structure for bellows processing

Abstract

This utility model discloses a cooling structure for bellows processing, relating to the field of bellows production technology. It includes two mating half-molds, a first half-mold and a second half-mold. The heat-conducting ring on the second half-mold is an independently set concentrated heat-conducting point, which can conduct heat away from the contact area between the bellows and the mold, improving cooling efficiency and thus forming efficient heat dissipation in specific areas of the bellows. This improves the overall heat conduction and heat dissipation efficiency of the mold. The flat, annular groove shape of the heat exchange annular groove increases the contact area between the cooling medium and the mold, improving heat exchange efficiency. The heat-conducting metal particles distributed on the inner wall further enhance the heat conduction performance. The columnar connecting grooves distributed on both sides of the first and second half-molds have a small diameter, thus the areas on both sides of the first and second half-molds have greater strength. This ensures that the first and second half-molds, after being assembled and installed on the injection molding machine, can well withstand the pressure applied by the limiting mechanism on the injection molding machine, improving the mold strength while further accelerating the mold's heat dissipation efficiency.

Description

Technical Field

[0001] This utility model relates to the field of corrugated pipe manufacturing technology, and specifically to a cooling structure for corrugated pipe processing. Background Technology

[0002] A corrugated pipe is a type of pipe made by connecting foldable corrugated sheets along the folding and stretching direction. It mainly includes metal corrugated pipes and plastic corrugated pipes, and is widely used in industries such as petrochemicals, instrumentation, aerospace, chemicals, power, water conservancy, and metallurgy.

[0003] Plastic corrugated pipes are produced by injection molding using molds. When the mold for corrugated pipe production is installed on the injection molding machine, a limiting structure is often set on the injection molding machine to ensure the sealing between the molds. This creates pressure on both sides of the mold, which requires the mold to have a certain strength. As a result, in order to ensure the strength during use, the water cooling grooves inside the mold are relatively narrow, which makes the heat dissipation effect of the mold poor and the cooling time long during use, thus reducing the production efficiency of corrugated pipes.

[0004] In summary, the existing corrugated pipe production molds have the problem that the internal water cooling grooves are relatively narrow, resulting in poor heat dissipation and long cooling time during use, which reduces the production efficiency of corrugated pipes. Utility Model Content

[0005] The purpose of this utility model is to provide a cooling structure for corrugated pipe processing, so as to solve the technical problem that the water cooling grooves inside the existing corrugated pipe production molds are relatively narrow, resulting in poor heat dissipation and long cooling time during use, which reduces the production efficiency of corrugated pipes.

[0006] The technical problem to be solved by this utility model can be achieved through the following technical solution:

[0007] A cooling structure for bellows processing.

[0008] It includes a first mold and a second mold that cooperate with each other, and the first mold and the second mold are fixedly connected by a locking member. The inner walls of the first mold and the second mold are provided with a corrugated groove and a corrugated groove, and the depth of the second corrugated groove is greater than the depth of the first corrugated groove. The inner wall of the second corrugated groove is provided with a heat-conducting ring, and the highest end of the heat-conducting ring is flush with the lowest end of the first corrugated groove.

[0009] Both the first and second half-molds have two sets of interconnected heat exchange ring grooves symmetrically opened at their upper and lower ends. The heat exchange ring grooves are located outside the first and second corrugated grooves. The width of the heat exchange ring grooves is greater than the width of the first and second corrugated grooves. The inner wall of the heat exchange ring grooves is distributed with many heat-conducting metal particles. Both sides of the first and second half-molds have symmetrically opened connecting grooves for connecting the heat exchange ring grooves.

[0010] Preferably, the locking element includes a bolt and a nut, the heat exchange annular groove is a flat annular groove, and the connecting groove is a columnar groove.

[0011] Preferably, both ends of the first half-mold and the second half-mold are symmetrically provided with fixing plates.

[0012] Preferably, the fixing plate has a threaded groove for installing a locking element.

[0013] Preferably, both the first and second half-molds are provided with two sets of liquid guide pipes connected to the heat exchange ring groove on their outer sides, with one set of liquid guide pipes for liquid inlet and the other set of liquid guide pipes for liquid outlet.

[0014] Preferably, a flow valve for controlling the flow rate of the cooling medium is provided on the outside of the liquid guide tube.

[0015] Preferably, both half-mold one and half-mold two have two sets of symmetrically distributed heat exchange chambers inside, and the heat exchange chambers are located between the corrugated groove two and the heat exchange ring groove.

[0016] Preferably, the heat exchange annular groove has an arc-shaped protrusion on its side wall near the heat exchange gas chamber.

[0018] Preferably, the materials of the first half-mold and the second half-mold are aluminum alloy.

[0019] The beneficial effects of this utility model are:

[0020] 1. In this utility model, the heat-conducting ring set on the inner wall of the second corrugated groove is an independently set concentrated heat-conducting point, which can quickly conduct heat away from the contact part between the corrugated pipe and the mold, improve cooling efficiency, and thus form efficient heat dissipation for the characteristic area on the corrugated pipe, thereby improving the overall heat conduction and heat dissipation efficiency of the mold. The heat exchange ring groove with the shape of a flat ring groove increases the contact area between the cooling medium and the mold, improving heat exchange efficiency. The heat-conducting metal particles distributed on the inner wall further enhance the heat conduction performance. The columnar connecting grooves distributed on both sides of the first and second half molds have a small diameter, so the area on both sides of the first and second half molds has greater strength, ensuring that the first and second half molds can adapt well to the pressure applied by the limiting mechanism on the injection molding machine after being assembled and installed on the injection molding machine, improving the strength of the mold and further accelerating the heat dissipation efficiency of the mold.

[0021] 2. In this utility model, the heat exchange chamber can assist in heat exchange and further improve the cooling efficiency. At the same time, the gas flow in the heat exchange chamber also helps to remove some heat. The arc-shaped protrusion can increase the heat exchange area, so that the heat in the heat exchange chamber can be transferred to the cooling medium flowing in the heat exchange ring groove more quickly, thereby improving the heat exchange efficiency.

Detailed Implementation

[0028] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.

[0029] like Figure 1-4 As shown, a cooling structure for bellows processing.

[0030] The device includes two mating mold halves, 1 and 2, which are fixedly connected by a locking element 5. This cooling structure mainly consists of the mating mold halves 1 and 2, which provide forming space for corrugated pipe processing and achieve cooling function through their internal structure. The locking element 5 includes bolts and nuts. Fixing plates 3 are symmetrically arranged at both ends of the mold halves 1 and 2. The fixing plates 3 have threaded grooves 4 for installing the locking element 5. When the device is in use, the mold halves 1 and 2 are assembled together, and the bolts are passed through the threaded grooves 4 and tightened with nuts, thereby fixing the mold halves 1 and 2 together tightly, ensuring the stability of the mold during corrugated pipe processing and ensuring the forming quality of the corrugated pipe.

[0031] Both half-mold 1 and half-mold 2 have corrugated grooves 8 and 9 on their inner walls, with the depth of corrugated groove 9 being greater than the depth of corrugated groove 8. A heat-conducting ring 10 is provided on the inner wall of corrugated groove 9, with the highest end of the heat-conducting ring 10 flush with the lowest end of corrugated groove 8. Both half-mold 1 and half-mold 2 have two sets of interconnected heat exchange ring grooves 12 symmetrically formed at their upper and lower ends, located outside corrugated grooves 8 and 9. The width of the heat exchange ring groove 12 is greater than that of corrugated groove 8. The widths of 8 and 9 of the corrugated groove are as follows: the heat exchange ring groove 12 is a flat ring groove, and numerous heat-conducting metal particles are distributed on the inner wall of the heat exchange ring groove 12. Symmetrical connecting grooves 14 for connecting the heat exchange ring groove 12 are provided on both sides of the inner surfaces of half-mold 1 and half-mold 2. The connecting grooves 14 are columnar grooves. Corrugated groove 8 and corrugated groove 9 provide the forming contour for the corrugated tube. A heat-conducting ring 10 is provided on the inner wall of corrugated groove 9, and the highest end of the heat-conducting ring 10 is flush with the lowest end of corrugated groove 8. This is an independently set feature. The heat-conducting ring 10 concentrates the heat dissipation point, which can quickly conduct heat away from the contact area between the bellows and the mold, improving cooling efficiency and thus forming efficient heat dissipation in the characteristic area of ​​the bellows. This improves the overall heat conduction and heat dissipation efficiency of the mold. After injection molding, the operator can selectively cut the protruding area on the outside of the bellows that matches the second bellows groove 9 to ensure the consistency of the bellows. The flat ring groove 12 increases the contact area between the cooling medium and the mold, improving heat exchange efficiency. The heat-conducting metal particles distributed on the inner wall further enhance the heat conduction performance. The heat exchange ring groove 12 is distributed at the upper and lower ends of half mold 1 and half mold 2. The columnar connecting groove 14 is distributed on both sides of half mold 1 and half mold 2. While connecting the heat exchange ring groove 12, the connecting groove 14 has a small diameter, so the area on both sides of half mold 1 and half mold 2 has greater strength, ensuring that half mold 1 and half mold 2 can adapt well to the pressure applied by the limiting mechanism on the injection molding machine after being assembled and installed.

[0032] In this embodiment, specifically, two sets of liquid guide pipes 6 connected to the heat exchange ring groove 12 are provided on the outer side of both half mold 1 and half mold 2. One set of liquid guide pipes 6 is used for liquid inlet and the other set of liquid guide pipes 6 is used for liquid outlet. A flow valve 7 for controlling the flow rate of cooling medium is provided on the outer side of the liquid guide pipes 6. The flow valve 7 can adjust the flow rate of cooling medium according to the actual situation of bellows processing, thereby controlling the heat dissipation efficiency and ensuring processing quality.

[0033] In this embodiment, specifically, two sets of symmetrically distributed heat exchange chambers 11 are provided inside both half-mold 1 and half-mold 2. The heat exchange chambers 11 are located between the corrugated groove 2 9 and the heat exchange ring groove 12. The heat exchange ring groove 12 has an arc-shaped protrusion 13 on the side wall near the heat exchange chamber 11. The heat exchange chambers 11 can assist in heat exchange and further improve cooling efficiency. At the same time, the gas flow in the heat exchange chambers 11 also helps to remove some heat. The arc-shaped protrusion 13 can increase the heat exchange area, so that the heat in the heat exchange chambers 11 can be transferred to the cooling medium flowing in the heat exchange ring groove 12 more quickly, thereby improving heat exchange efficiency.

[0034] In this embodiment, specifically, the outer walls of half mold 1 and half mold 2 are provided with compensation grooves 15. The compensation grooves 15 are used to compensate for the deformation of the mold during thermal expansion and contraction, so as to ensure the accuracy of the mold.

[0035] In this embodiment, specifically, the materials of half mold 1 and half mold 2 are aluminum alloys. Aluminum alloys have good thermal conductivity and can quickly conduct away the heat generated during the processing of the corrugated pipe.

[0036] The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0037] The working principle of this utility model is as follows: When the device is in use, half mold 1 and half mold 2 are fixed together by locking member 5. Then, multiple sets of devices are installed on the injection molding machine. The injection molding machine injects molding into the mold. Cooling medium is injected into the heat exchange ring groove 12 through a set of liquid guide pipes 6. The flow valve 7 controls the flow rate of the cooling medium. After absorbing heat, the cooling medium is discharged from another set of liquid guide pipes 6. The heat generated by the pipe is conducted to the cooling medium through the heat conduction ring 10, heat exchange ring groove 12, heat exchange air chamber 11 and other structures. The cooling medium carries away the heat, thereby cooling the corrugated pipe. After the corrugated pipe is processed, the locking member 5 is loosened, half mold 1 and half mold 2 are separated, and the shaped corrugated pipe is taken out.

[0038] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
