Description

Technical Field

[0001] The utility model relates to the technical field of forming molds, in particular to a demoulding mold for radiators. Background Art

[0002] With the development of society and the progress of technology, both the living standard and the quality of life have been improved, and the housing conditions are also better. Especially in the north, when the weather is cold in winter, there are heating and heat dissipation devices in every household's indoor to ensure the indoor temperature.

[0003] At present, in order to achieve the purpose of less material consumption and good heat dissipation effect of radiators, the wall thickness of the heat source circulating water flow pipeline and the connection port of the radiator should be as small as possible. Now the wall thickness is designed to be no more than 4 mm to achieve a better heat dissipation effect. However, in the process of producing the above-mentioned radiators, to successfully demould the formed radiators, a push tube needs to be set to act on the connection port. But due to the too small wall thickness at the connection port, with the traditional push tube structure, it is easy to break during the ejection process and the radiator cannot be successfully ejected. Therefore, a push tube device is urgently needed to demould the radiator repeatedly. Summary of the Utility Model

[0004] In order to overcome the shortcomings in the prior art, the purpose of the utility model is to provide a demoulding mold for radiators.

[0005] To achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A demoulding mold for radiators, comprising an upper mold, a lower mold, a mold core and an ejection mechanism. A cavity for forming a radiator is formed between the upper mold and the lower mold. The mold core is arranged in the cavity. The ejection mechanism is connected to the lower mold. The ejection mechanism includes an ejection fixing rod, a push tube, a cooling rod and a seal. One end of the ejection fixing rod passes through the lower mold and is arranged in the cavity. The push tube is sleeved on the ejection fixing rod. A first cooling channel is opened inside the ejection fixing rod. The cooling rod is fixedly connected in the first cooling channel. A second cooling channel is opened inside the cooling rod. An inlet and an outlet are opened on the ejection fixing rod. The inlet is communicated with the second cooling channel of the cooling rod, and the outlet is communicated with the first cooling channel. The seal is fixedly connected to one end of the ejection fixing rod.

[0007] Compared with the prior art, the demoulding mold for radiators of the present application has the following beneficial effects:

[0008] In actual application, by improving the shape of the ejector tube, the cross-section of the ejector tube is designed to be annular, so as to increase the contact area with the connection port of the radiator and improve the success rate of demolding. A cooling water flow channel is also arranged inside the ejection fixing rod. The cooling water flows from the water inlet to the cooling water port of the cooling rod, then enters the second cooling channel, flows from one end of the second cooling channel into the first cooling channel of the ejection fixing rod, and finally flows out from the water outlet to complete the water circulation. By setting like this, the temperature of the ejection fixing rod is reduced, which is beneficial to cyclic demolding and reduces the wear between the bushings.

[0009] Preferably, the wall thickness of the cross-section of the top of the ejector tube is equal to or less than that of the cross-section of the connection port of the radiator.

[0010] Beneficial effects: By setting the cross-sectional diameter of the top of the ejector tube to be the same as or less than the diameter of the radiator by 0.5 mm of the unilateral diameter dimension, the ejector tube is in balanced contact when demolding and ejecting, with a larger contact area, reducing the probability of damage to the radiator and facilitating the repeated use of the ejector tube.

[0011] Preferably, a first oil cylinder and a movable die core are further provided. The first oil cylinder is fixedly connected to the top of the lower die. A movable die core is movably connected to the first oil cylinder. A first through hole is provided on the die core. The movable die core passes through the first through hole and abuts against one end of the ejection fixing rod.

[0012] Preferably, movable slideways are provided on both the first oil cylinder and the lower die. Oil pressure sliders are movably arranged on the movable slideways. The oil pressure sliders are fixedly connected to the movable die core.

[0013] Beneficial effects: By setting the first oil cylinder to drive the movable die core to move up and down, the movable die core can be moved upward after the radiator is cast, facilitating the demolding operation of the ejection mechanism for the radiator.

[0014] Preferably, the die core includes a fixed locking block and an inclined locking block. The fixed locking block and the inclined locking block are spliced at the center to form a casting cavity. A radiator module is arranged in the casting cavity.

[0015] Beneficial effects: This die core adopts a central assembly method, different from the traditional two-side assembly method. By setting the fixed locking block to be fixed at the center and bottom positions of the cavity as a reference point to calibrate the position of the subsequent installed radiator module, and the inclined locking block is fixed at the top and left and right sides of the radiator module. By setting like this, the problem that all modules need to be completely removed and calibrated when replacing the radiator module is greatly reduced, saving the time for replacing the module.

[0016] Preferably, an annular groove is arranged inside the ejector tube, and an annular convex ring is arranged on the ejection fixing rod. The annular groove is matched with the annular convex ring.

[0017] Beneficial effects: By providing a circular convex ring that cooperates with a circular groove, when the ejector fixing rod is driven by a power mechanism, it can drive the push tube to move and demold the radiator.

[0018] Preferably, a cooling port is provided on the cooling rod, one end of the cooling port communicates with the second cooling channel, and the other end of the cooling port communicates with the water inlet.

[0019] Beneficial effects: By providing a cooling port on the cooling rod, cooling water can flow through the water inlet to the second cooling channel to cool the push tube mechanism. Description of the Drawings

[0030] The following is a further detailed description through specific embodiments

[0031] The reference numerals in the accompanying drawings of the specification include: upper die 1, lower die 2, die core 3, ejection mechanism 4, cavity 5, ejection fixing rod 6, ejector tube 7, cooling rod 8, seal 9, first cooling channel 10, second cooling channel 11, water inlet 12, water outlet 13, top of the ejector tube 14, radiator connection port 15, first oil cylinder 16, movable die core 17, first through hole 18, movable slideway 19, oil pressure slider 20, fixed locking block 21, inclined surface locking block 22, casting cavity 23, radiator module 24, annular groove 25, annular convex ring 26, cooling port 27, radiator 28.

[0032] As shown in the Figures 1-10 accompanying drawings: This embodiment shows a demoulding die for a radiator, including an upper die 1, a lower die 2, a die core 3 and an ejection mechanism 4. A cavity 5 for forming the radiator 28 is formed between the upper die 1 and the lower die 2. The die core 3 is arranged in the cavity 5. The ejection mechanism 4 is connected to the lower die 2. The ejection mechanism 4 includes an ejection fixing rod 6, an ejector tube 7, a cooling rod 8 and a seal 9. One end of the ejection fixing rod 6 passes through the lower die 2 and is arranged in the cavity 5. The ejector tube 7 is sleeved on the ejection fixing rod 6. A first cooling channel 10 is provided inside the ejection fixing rod 6. The cooling rod 8 is fixedly connected inside the first cooling channel 10. A second cooling channel 11 is provided inside the cooling rod 8. Water inlets 12 and water outlets 13 are provided on the ejection fixing rod 6. The water inlet 12 is communicated with the second cooling channel 11 of the cooling rod 8, and the water outlet 13 is communicated with the first cooling channel 10. The seal 9 is fixedly connected to one end of the ejection fixing rod 6.

[0033] Specifically, by making the cross-sectional shape of the ejector tube 7 match the cross-section of the radiator connection port 15, the contact area during demoulding can be increased in this way, the ejection is more balanced, and the success rate of demoulding is improved. A cooling water circulation channel is also provided inside the ejection fixing rod 6. Cooling water flows from the water inlet 12 to the cooling port 27 inside the cooling rod 8, then flows from the cooling port 27 to the second cooling channel 11. The end of the second cooling channel 11 is communicated with the first cooling channel 10. Finally, the cooling water flows out from the water outlet 13 to complete the water circulation. In this way, the temperature of the ejector mechanism 4 is reduced, and the wear of the guide sleeve during demoulding is reduced.

[0034] As shown in the Figure 5 and 8 accompanying drawings: The cross-section of the top of the ejector tube 14 in this embodiment is equal to or smaller than the wall thickness of the cross-section of the radiator connection port 15.

[0035] Specifically, the cross-sectional diameter of the top of the ejector tube 14 is set to a circular ring shape that is the same as the shape of the radiator connection port 15, or the cross-sectional diameter of the top of the ejector tube 14 is set to a circular ring shape that is 0.5 mm smaller than the single-side diameter of the radiator connection port 15, which is convenient for contacting the radiator connection port 15 during demoulding. The increased contact area reduces the probability of the radiator being damaged during demoulding.

[0036] As shown Figure 2 in the figure: In this embodiment, a first oil cylinder 16 and a movable die core 17 are further provided. The first oil cylinder 16 is fixedly connected to the top of the lower die 2. A movable die core 17 is movably connected to the first oil cylinder 16. A first through hole 18 is formed in the die core 3. The movable die core 17 passes through the first through hole 18 and abuts against one end of the ejection fixing rod 6.

[0037] As shown Figure 2 in the figure: In this embodiment, movable slideways 19 are formed in both the first oil cylinder 16 and the lower die 2. Oil pressure sliders 20 are movably arranged on the movable slideways 19. The oil pressure sliders 20 are fixedly connected to the movable die core 17.

[0038] Specifically, the first oil cylinder 16 drives the movable die core 17 to move up and down, ensuring that the movable die core 17 can pass through the die core 3 and be connected in the casting cavity 23 during the pouring process. When demolding is required after pouring is completed, the first oil cylinder 16 drives the movable die core to move upward, so that the push tube 7 can eject the radiator 28 to complete demolding.

[0039] As shown Figure 7 in the figure: The die core 3 of this embodiment includes a fixed locking block 21 and an inclined locking block 22. The fixed locking block 21 and the inclined locking block 22 are spliced at the center to form a casting cavity 23. A radiator module 24 is arranged in the casting cavity 23.

[0040] Specifically, the radiator module 24 is installed in the casting cavity 23 by a central assembly method, that is, the fixed locking block 21 is determined as the reference surface. The fixed locking block 21 is installed at the center point and the bottom feed port of the casting cavity 23. Then the radiator modules 24 are assembled in sequence from both sides. Finally, the inclined locking block 22 is fixed on the top and both sides of the radiator module 24. The advantage of such a setting is that if there is an error in one side of the radiator module 24, only the module on that side needs to be removed for calibration, without the need to disassemble all of them, saving the assembly time.

[0041] As shown Figures 4-6 in the figure: An annular groove 25 is formed inside the push tube 7 of this embodiment. An annular convex ring 26 is arranged on the ejection fixing rod 6. The annular groove 25 is matched with the annular convex ring 26.

[0042] Specifically, by abutting the annular groove 25 against the annular convex ring 26, when the power device pushes the ejection fixing rod 6, the push tube 7 can be driven to move, so as to realize the effect of ejecting the radiator 28 to complete demolding.

[0043] As shown Figure 9 in the figure: A cooling port 27 is formed in the cooling rod 8 of this embodiment. One end of the cooling port 27 is communicated with the second cooling channel 11, and the other end of the cooling port 27 is communicated with the water inlet 12.

[0044] Specifically, by opening the cooling port 27, cooling water can be connected to the second cooling channel 11 through the cooling port 27, facilitating the water circuit circulation.

[0045] The above are only embodiments of the present invention. Specific technical solutions and / or common knowledge such as characteristics well known in the art are not described in detail herein. It should be noted that for those skilled in the art, without departing from the technical solution of the present invention, several deformations and improvements can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the implementation effect of the present invention and the practicality of the patent.
