Description

Technical Field

[0001] This utility model relates to the field of inductor manufacturing technology, specifically a hot pressing mold for a hot pressing device used in inductor manufacturing. Background Technology

[0002] An inductor is a component that converts electrical energy into magnetic energy and stores it. The structure of an inductor is similar to a transformer, but it has only one winding. An inductor has a certain inductance, which only impedes changes in current. If no current is flowing through the inductor, it will attempt to impede the current flow when the circuit is closed; if current is flowing through the inductor, it will attempt to maintain a constant current when the circuit is open. Inductors are also called chokes, reactors, or dynamic reactors.

[0003] In the hot pressing process of inductors, the traditional hot pressing mold does not close the upper and lower molds accurately, which affects the hot pressing effect. At the same time, the traditional hot pressing mold is not convenient for cooling the overheated mold after hot pressing, which affects the subsequent mold processing. Therefore, it is necessary to design a hot pressing mold for hot pressing devices in inductor production. Utility Model Content

[0004] The purpose of this invention is to provide a hot pressing mold for a hot pressing device used in the production of inductors, so as to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a hot pressing mold for a hot pressing device for inductor production, comprising a base plate, a column disposed on the top of the base plate, a top plate disposed on the top of the column, and a cylinder disposed on the top plate. The output end of the cylinder is connected to an adjusting plate. An upper mounting seat is fixed at the bottom of the adjusting plate. An upper mold base is mounted on the bottom of the upper mounting seat through an upper fixing mechanism. A lower mounting seat is disposed at the top of the base plate directly below the upper mold base. A lower mold base is mounted on the top of the lower mounting seat through a lower fixing mechanism.

[0006] A frustum-shaped mold cavity is provided in the middle of the top of the lower mold base, and a cooling section is provided on the lower mold base outside the frustum-shaped mold cavity;

[0007] The cooling section includes a heat-conducting shell located outside the frustum mold cavity. The heat-conducting shell is provided with an inclined platform. A lower cooling groove is provided at the lower part of the inclined platform, and an upper cooling groove is provided at the upper part of the inclined platform. Several liquid guiding grooves for connecting the lower cooling groove and the upper cooling groove are provided on the inclined platform.

[0008] The lower mold base is provided with a circulating liquid delivery mechanism on its outer side for introducing coolant into the lower and upper cooling tanks or exporting coolant from the lower and upper cooling tanks. The upper mold base is stabilized by the upper fixing mechanism, and the lower mold base is fixed by the lower fixing mechanism. This facilitates accurate mold closing by pushing the upper mold base toward the lower mold base with a cylinder. When the mold in the lower mold base needs to be cooled after hot pressing, coolant is introduced into the lower and upper cooling tanks through the circulating liquid delivery mechanism. The overheated mold located in the frustum mold cavity transfers heat to the heat-conducting shell, and then exchanges heat with the coolant to achieve the cooling operation of the mold, which facilitates subsequent mold processing operations.

[0009] In a further embodiment, the circulating infusion mechanism includes a coolant storage tank located on one side of the lower mounting base. The coolant storage tank is provided with an inlet pipe and an outlet pipe. An inlet pump is provided on the inlet pipe, and a valve is provided on the outlet pipe.

[0010] The heat-conducting shell is equipped with two liquid guide heads. One end of each liquid guide head extends into the bottom of the lower cooling tank, and a liquid guide hole communicating with the lower cooling tank is opened on the liquid guide head. One end of the liquid inlet pipe and the liquid outlet pipe are respectively connected to the adjacent liquid guide head. After the mold is hot-pressed in the frustum mold cavity, the heat in the lower part of the mold is more difficult to dissipate than the heat in the upper part of the mold due to the small space in the lower part of the frustum mold cavity and the large space in the upper part of the mold. When the mold needs to be cooled, the valve is closed, and the coolant in the coolant storage tank is injected into the lower cooling tank through the liquid guide hole on the liquid guide head by the liquid inlet pipe and the liquid inlet pump. This fully exchanges the heat in the lower part of the mold. The coolant continuously injected into the lower cooling tank enters the upper cooling tank through the liquid guide tank to exchange the heat in the upper part of the mold. Thus, the cooling efficiency of the mold is guaranteed without the need for a large amount of coolant. After a period of time, the valve is opened, and the coolant that has absorbed heat flows back to the coolant storage tank through the liquid outlet pipe for cooling. The cooled coolant continues to be transported to the cooling section through the liquid inlet pipe to realize the circulation of coolant.

[0011] In a further embodiment, the top of the heat-conducting shell is provided with a plurality of heat-conducting pillars, the bottom of which extends into the upper cooling tank. The arrangement of the heat-conducting pillars facilitates the further extraction of heat from the coolant that has absorbed heat in the upper cooling tank.

[0012] In a further embodiment, the upper fixing mechanism includes an upper pad fixed to the bottom of the upper mounting base, an upper fixing plate fixed to the bottom of the upper pad, an upper mold base disposed at the bottom of the upper fixing plate, and an upper positioning post fixed to the upper pad, which passes through the upper fixing plate and the upper mold base in sequence.

[0013] The lower fixing mechanism includes a lower pad plate fixed to the top of the lower mounting base, a lower fixing plate fixed to the top of the lower pad plate, a lower mold base disposed on the top of the lower fixing plate, and a lower positioning post penetrating the lower fixing plate fixed to the lower pad plate.

[0014] The lower mold base has an upper positioning hole at its top that mates with the upper positioning pin, and a lower positioning hole at its bottom that mates with the lower positioning pin. The upper positioning pin, in conjunction with the upper pad and the upper fixing plate, stabilizes the upper mold base. The lower positioning pin extends into the lower positioning hole and, in conjunction with the lower pad and the lower fixing plate, stabilizes the lower mold base. During the mold closing process of the upper and lower mold bases, the upper positioning pin extends into the upper positioning hole, ensuring accurate mold closing between the upper and lower mold bases.

[0015] In a further embodiment, the lower mold base is provided with a plurality of heat dissipation holes. The heat dissipation effect of the lower mold base is improved by setting the heat dissipation holes, thereby improving the heat dissipation effect of the mold.

[0016] In a further embodiment, a guide sleeve is fixed at the bottom of the upper mounting base, and a guide post is fixed at the top of the lower mounting base. A guide groove is provided on the guide sleeve to cooperate with the guide post. The cooperation between the guide sleeve and the guide post ensures accurate mold closing between the upper mold base and the lower mold base.

[0017] In a further embodiment, guide blocks are installed at both ends of the adjusting plate, and the guide blocks are slidably sleeved on the column. The guide blocks ensure that the adjusting plate moves stably up and down along the column.

[0018] In a further embodiment, the coolant storage tank is equipped with a cooling fan, and the coolant storage tank has an exhaust vent. The coolant storage tank is also equipped with a coolant inlet pipe and a coolant outlet pipe. The cooling fan, in conjunction with the exhaust vent, facilitates the cooling of the coolant flowing back into the coolant storage tank. The coolant inlet pipe and coolant outlet pipe facilitate the replacement of the coolant that has been used for a long time in the coolant storage tank.

[0019] Compared with the prior art, the beneficial effects achieved by this utility model are as follows: the upper mold base is stabilized by the upper fixing mechanism, and the lower mold base is stabilized by the lower fixing mechanism, which facilitates the accurate mold closing by pushing the upper mold base toward the lower mold base with a cylinder. When the mold in the lower mold base needs to be cooled after hot pressing, coolant is introduced into the lower cooling tank and the upper cooling tank through the circulating liquid delivery mechanism. The overheated mold located in the frustum mold cavity transfers heat to the heat-conducting shell, and then exchanges heat with the coolant to realize the cooling operation of the mold, which facilitates the subsequent mold processing operation.

Detailed Implementation

[0026] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the invention. However, it will be apparent to those skilled in the art that the invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid obscuring the invention.

[0027] Please see Figure 1-5 This utility model provides a technical solution: a hot pressing mold for a hot pressing device for inductor production, including a base plate 1, a column 2 on the top of the base plate 1, a top plate 3 on the top of the column 2, and a cylinder 4 on the top plate 3. The output end of the cylinder 4 is connected to an adjusting plate 5. An upper mounting seat 7 is fixed at the bottom of the adjusting plate 5. An upper mold base 10 is mounted on the bottom of the upper mounting seat 7 through an upper fixing mechanism. A lower mounting seat 12 is provided on the top of the base plate 1 directly below the upper mold base 10. A lower mold base 15 is mounted on the top of the lower mounting seat 12 through a lower fixing mechanism, wherein the lower mold base 15 is located directly below the upper mold base 10.

[0028] A frustum-shaped mold cavity 19 is provided in the middle of the top of the lower mold base 15, and a cooling section 20 is provided on the lower mold base 15 outside the frustum-shaped mold cavity 19.

[0029] The cooling section 20 includes a heat-conducting shell 21 located outside the frustum mold cavity 19. The heat-conducting shell 21 is provided with a ramp 22. A lower cooling groove 23 is provided at the lower part of the ramp 22, and an upper cooling groove 24 is provided at the upper part of the ramp 22. A plurality of liquid guiding grooves 25 are provided on the ramp 22 to connect the lower cooling groove 23 and the upper cooling groove 24.

[0030] The lower mold base 15 is provided with a circulating liquid delivery mechanism on its outer side for introducing coolant into the lower cooling tank 23 and the upper cooling tank 24 or for exporting coolant from the lower cooling tank 23 and the upper cooling tank 24. The upper mold base 10 is stabilized by the upper fixing mechanism, and the lower mold base 15 is stabilized by the lower fixing mechanism. This facilitates the accurate mold closing by pushing the upper mold base 10 toward the lower mold base 15 with the cylinder 4. When the mold in the lower mold base 15 needs to be cooled after hot pressing, coolant is introduced into the lower cooling tank 23 and the upper cooling tank 24 through the circulating liquid delivery mechanism. The overheated mold located in the frustum mold cavity 19 transfers heat to the heat-conducting shell 21, and then exchanges heat with the coolant to achieve the cooling operation of the mold, which facilitates the subsequent processing of the mold.

[0031] In a further embodiment, the circulating infusion mechanism includes a coolant storage tank 29 located on one side of the lower mounting base 12. The coolant storage tank 29 is provided with an inlet pipe 30 and an outlet pipe 32. The inlet pipe 30 is provided with an inlet pump 31, and the outlet pipe 32 is provided with a valve 33.

[0032] The heat-conducting shell 21 is equipped with two liquid guide heads 26. One end of each liquid guide head 26 extends into the bottom of the lower cooling tank 23. Each liquid guide head 26 has a liquid guide hole 27 communicating with the lower cooling tank 23. One end of the liquid inlet pipe 30 and the liquid outlet pipe 32 are respectively connected to the adjacent liquid guide head 26. After hot pressing in the frustum mold cavity 19, the heat in the lower part of the mold is more difficult to dissipate than the heat in the upper part due to the smaller lower space and larger upper space of the frustum mold cavity 19. When cooling of the mold is required, the valve 33 is closed, and the liquid inlet pipe 30 and the liquid inlet pump 31 work together to cool the liquid in the coolant storage tank 29. The coolant is injected into the lower cooling tank 23 through the guide hole 27 on the guide head 26, which fully exchanges heat with the lower part of the mold. The coolant continuously injected into the lower cooling tank 23 enters the upper cooling tank 24 through the guide groove 25, which exchanges heat with the upper part of the mold. Thus, the cooling efficiency of the mold is guaranteed without the need for a large amount of coolant. After a period of time, the valve 33 is opened, and the coolant that has absorbed heat flows back to the coolant storage tank 29 through the outlet pipe 32 for cooling. The cooled coolant continues to be transported to the cooling section 20 through the inlet pipe 30, realizing the circulation of coolant.

[0033] In a further embodiment, the top circumferential of the heat-conducting shell 21 is provided with a plurality of heat-conducting pillars 28, the bottom of which extends into the upper cooling tank 24. The arrangement of the heat-conducting pillars 28 facilitates the further export of heat from the coolant that absorbs heat in the upper cooling tank 24. A fan is provided on the outside of the upper mold base 10 to carry away the heat exported by the heat-conducting pillars 28.

[0034] In a further embodiment, the upper fixing mechanism includes an upper pad 8 fixed to the bottom of the upper mounting base 7, an upper fixing plate 9 fixed to the bottom of the upper pad 8, an upper mold base 10 disposed at the bottom of the upper fixing plate 9, and an upper positioning post 11 fixed on the upper pad 8, which passes through the upper fixing plate 9 and the upper mold base 10 in sequence.

[0035] The lower fixing mechanism includes a lower pad 13 fixed to the top of the lower mounting base 12, a lower fixing plate 14 fixed to the top of the lower pad 13, a lower mold base 15 located on the top of the lower fixing plate 14, and a lower positioning post that penetrates the lower fixing plate 14 fixed on the lower pad 13.

[0036] The lower mold base 15 has an upper positioning hole 16 at the top that mates with the upper positioning pin 11, and a lower positioning hole at the bottom that mates with the lower positioning pin. The upper positioning pin 11, in conjunction with the upper pad 8 and the upper fixing plate 9, stabilizes the upper mold base 10. The lower positioning pin extends into the lower positioning hole and, in conjunction with the lower pad 13 and the lower fixing plate 14, stabilizes the lower mold base 15. During the mold closing process of the upper mold base 10 and the lower mold base 15, the upper positioning pin 11 extends into the upper positioning hole 16, ensuring accurate mold closing of the upper mold base 10 and the lower mold base 15.

[0037] In a further embodiment, a plurality of heat dissipation holes 34 are provided on the lower mold base 15. The heat dissipation effect of the lower mold base 15 is improved by the setting of the heat dissipation holes 34, thereby improving the heat dissipation effect of the mold. The lower mold base 15 is cooled by air by a fan on the outside of the upper mold base 10.

[0038] In a further embodiment, a guide sleeve 17 is fixed at the bottom of the upper mounting base 7, and a guide post 18 is fixed at the top of the lower mounting base 12. A guide groove is provided on the guide sleeve 17 to cooperate with the guide post 18. Through the cooperation between the guide sleeve 17 and the guide post 18, the upper mold base 10 and the lower mold base 15 can be accurately closed.

[0039] In a further embodiment, guide blocks 6 are installed at both ends of the adjusting plate 5. The guide blocks 6 are slidably sleeved on the column 2. The setting of the guide blocks 6 makes the adjusting plate 5 move up and down stably along the column 2.

[0040] In a further embodiment, the coolant storage tank 29 is equipped with a cooling fan, and the coolant storage tank 29 is provided with an exhaust port. The coolant storage tank 29 is also provided with a coolant inlet pipe and a coolant outlet pipe. The cooling fan, in conjunction with the exhaust port, facilitates the cooling of the coolant flowing back into the coolant storage tank 29. The coolant inlet pipe and coolant outlet pipe facilitate the replacement of the coolant that has been used for a long time in the coolant storage tank 29.

[0041] Working principle: The cylinder 4 pushes the adjusting plate 5 downward, which in turn pushes the upper mounting base 7 downward, so that the upper mold base 10 below the upper mounting base 7 and the lower mold base 15 directly below the upper mold base 10 can close together. The upper positioning pin 11, in conjunction with the upper pad 8 and the upper fixing plate 9, stabilizes the upper mold base 10. The lower positioning pin extends into the lower positioning hole, in conjunction with the lower pad 13 and the lower fixing plate 14, to stabilize the lower mold base 15. During the mold closing process of the upper mold base 10 and the lower mold base 15, the upper positioning pin 11 extends into the upper positioning hole 16, so that the upper mold base 10 and the lower mold base 15 close together accurately. The guide sleeve 17 cooperates with the guide pin 18 to ensure accurate mold closing of the upper mold base 10 and the lower mold base 15. When the mold in the lower mold base 15 needs to be cooled after hot pressing, the valve 33 is closed and the liquid inlet pipe 3... In conjunction with the inlet pump 31, the coolant in the coolant storage tank 29 is injected into the lower cooling tank 23 through the guide hole 27 on the guide head 26. The overheated mold located in the frustum mold cavity 19 transfers heat to the heat-conducting shell 21, and then exchanges heat with the coolant, fully exchanging heat at the bottom of the mold. The coolant continuously injected into the lower cooling tank 23 enters the upper cooling tank 24 through the guide groove 25 to exchange heat at the top of the mold, thus ensuring the cooling efficiency of the mold without requiring a large amount of coolant. After a period of time, the valve 33 is opened, and the coolant that has absorbed heat flows back to the coolant storage tank 29 through the outlet pipe 32 for cooling. The cooled coolant continues to be transported to the cooling section 20 through the inlet pipe 30, realizing the circulation of coolant and facilitating subsequent mold processing operations.
