Description

Technical Field

[0001] This utility model relates to an injection mold, specifically a high-efficiency mold for forming the base of an aromatherapy diffuser. Background Technology

[0002] Aroma diffuser base molds are specialized injection molding tools used for the mass production of aroma diffuser base components. They are made by injecting high-temperature molten plastic into an injection tank and allowing it to cool and solidify.

[0003] In existing aroma diffuser base molds, after molten material is injected into the injection tank, a large amount of heat accumulates in the space at the top of the injection tank due to the characteristic that heat rises. Since the cooling system of the aroma diffuser base mold has the same heat dissipation structure at different depths, the heat dissipation rate is the same at different depths. This results in the slowest heat dissipation at the top of the injection tank, leading to different cooling rates of the molten material at different depths. Consequently, the material of the aroma diffuser base produced has poor uniformity at different heights. Utility Model Content

[0004] The purpose of this invention is to provide a high-efficiency mold for forming the base of an aroma diffuser. The cooling rate is basically the same at different depths, and the material uniformity at different heights of the formed aroma diffuser base is better, overcoming the problem of poor material uniformity caused by different cooling rates of molten material at different depths in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency molding mold for an aromatherapy diffuser base, comprising an upper mold base and a lower mold base disposed below the upper mold base. The structures of both the upper and lower mold bases are existing technologies and will not be described in detail here. The lower mold base includes a base and a cooling mechanism is provided on it. The cooling mechanism includes a refrigerant pool and a waste liquid pool disposed on one side of the refrigerant pool. Both the refrigerant pool and the waste liquid pool are cavity structures with openings at the top and hollow interiors. Both the refrigerant pool and the waste liquid pool are fixed to the lower mold base. A pump body is fixed on the refrigerant pool, and a delivery pipe, a distribution pipe, and a control pipe are sequentially connected to the pump body. The refrigerant inlet pipe and the cold flow pipe are equipped with a heat-conducting component inside the cold flow pipe. There are multiple sets of refrigerant inlet pipes, cold flow pipes, and heat-conducting components. The multiple sets of cold flow pipes gradually move away from the injection molding tank from top to bottom. This is because the heat of the molten material in the injection molding tank will gradually rise. Therefore, in order to make the heat at different depths in the injection molding tank more evenly dissipated, the upper cold flow pipe needs to be closer to the injection molding tank. The heat-conducting component includes a copper sheet and a heat spreader and heat pipes arranged sequentially on the copper sheet. The copper sheet is fixed inside the base and embedded in the inner wall of the injection molding tank, so that the copper sheet can directly absorb the heat of the molten material in the injection molding tank.

[0006] Preferably, an injection groove is provided on the upper surface of the base, and multiple sets of heat conduction chambers are provided on the outer side of the injection groove. Each set of heat conduction chambers has three units, each set of cold flow pipes and each set of heat conduction components have three units, and each set of cold flow pipes and each set of heat conduction components are located in one set of heat conduction chambers.

[0007] Preferably, there are multiple liquid outlets, and each of the multiple liquid outlets is connected to multiple sets of refrigerant inlet pipes.

[0008] Preferably, all sets of cold flow pipes are horizontally arranged and are arranged around the outer circle of the injection molding tank, so that all sets of cold flow pipes can absorb heat from the outer circle of the injection molding tank.

[0009] Preferably, the two ends of the heat spreader are fixed to the copper sheet and the heat pipe respectively. Each heat spreader is provided with multiple heat pipes that are evenly distributed. The heat pipes are U-shaped and have different lengths at different depths. The heat pipes at the top have smaller lengths and the heat pipes at the bottom have larger lengths.

[0010] Preferably, a copper plate is fixed to the end of multiple heat pipes away from the heat spreader. The copper plate is fixed to the outer circle of the cold flow pipe and to the inner wall of the base, so that the structure of the copper plate remains stable. Half of the outer circle of the cold flow pipe is fixed to the base, and the other half is in contact with the copper plate, so as to better absorb the heat on the copper plate.

[0011] Preferably, the heat-conducting assembly further includes a support fixed to the bottom of the multiple heat pipes; the support is used to support the multiple heat pipes.

[0012] Preferably, the ends of the multiple cold flow pipes furthest from the refrigerant inlet pipe are all connected to refrigerant outlet pipes, and the multiple refrigerant outlet pipes are all located above the waste liquid pool.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model, by setting up multiple sets of refrigerant inlet pipes and multiple sets of cold flow pipes at different heights, covers the heat dissipation at different depths in the injection molding tank. The distance between the multiple sets of cold flow pipes and the injection molding tank gradually decreases from bottom to top, so that the heat accumulated at the top of the injection molding tank can be dissipated more quickly through the cold flow pipes located at the top. This allows the cooling effect of the coolant to be more evenly distributed throughout the injection molding tank. Therefore, during the molding process, the molten material at different depths in the injection molding tank cools more evenly, and the cooling rate at different depths is basically the same. The uniformity of the material at different heights of the molded aroma diffuser base is better.

[0015] 2. This utility model, through the setting of multiple sets of cold flow pipes, simultaneously discharges heat from different depths in the injection molding tank. Each set of cold flow pipes is equipped with a large area of ​​copper sheet and heat spreader plate on the inner side, which makes the heat absorption faster and accelerates the molding rate, thus realizing the efficient molding process of the aroma diffuser base.

Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0026] Please see Figure 1 One embodiment of this utility model is a high-efficiency mold for forming the base of an aromatherapy machine, which includes an upper mold base 1 and a lower mold base 2 disposed below the upper mold base 1. The structures of the upper mold base 1 and the lower mold base 2 are existing technologies and will not be described in detail here. A cooling mechanism 3 is provided on the lower mold base 2.

[0027] Please see Figure 2 The lower mold base 2 includes a base 21, and the cooling mechanism 3 includes a refrigerant pool 31 and a waste liquid pool 32 disposed on one side of the refrigerant pool 31. Both the refrigerant pool 31 and the waste liquid pool 32 are cavity structures with an opening at the top and a hollow interior. Both the refrigerant pool 31 and the waste liquid pool 32 are fixed on the lower mold base 2. A pump body 33 is fixed on the refrigerant pool 31. The cooling mechanism 3 also includes multiple refrigerant output pipes 39 fixed on the base 21.

[0028] Please see Figure 3The pump body 33 is connected in sequence to a delivery pipe 34, a diversion pipe 35 and multiple sets of refrigerant input pipes 36. One end of the delivery pipe 34 is connected to the diversion pipe 35, and the other end extends into the interior of the refrigerant pool 31 and draws refrigerant from the refrigerant pool 31. The diversion pipe 35 is provided with multiple liquid outlets, and the multiple liquid outlets are respectively connected to multiple sets of refrigerant input pipes 36.

[0029] Please see Figure 4 An injection molding groove 22 is provided on the upper surface of the base 21, and multiple sets of heat conduction chambers 23 are provided on the outer side of the injection molding groove 22. The volume of the multiple sets of heat conduction chambers 23 gradually increases from top to bottom.

[0030] Please see Figure 5 Multiple refrigerant inlet pipes 36 are connected to cold flow pipes 37 at their ends away from the distribution pipe 35. A heat-conducting component 38 is installed inside the cold flow pipe 37. Multiple sets of refrigerant inlet pipes 36, cold flow pipes 37, and heat-conducting components 38 are provided. The multiple sets of cold flow pipes 37 gradually move away from the injection molding tank 22 from top to bottom. This is because the heat from the molten material in the injection molding tank 22 gradually rises. Therefore, to ensure that the heat at different depths within the injection molding tank 22 is dissipated more evenly, the upper cold flow pipes 37 need to be closer to the injection molding tank 22. The heat-conducting component 38 includes a copper sheet 381 and a heat spreader 382 and heat pipes 383 sequentially arranged on the copper sheet 381. The copper sheet 381 is fixed inside the base 21 and embedded in the inner wall of the injection molding tank 22, allowing the copper sheet 381 to directly absorb the heat from the molten material in the injection molding tank 22. The two ends of the heat spreader 382 are respectively connected to the copper sheet 381. 1. Heat pipes 383 are fixed to each heat spreader 382. Each heat spreader 382 is equipped with multiple heat pipes 383. The heat pipes 383 are U-shaped and have different lengths at different depths. The heat pipes 383 at the top have shorter lengths and the heat pipes 383 at the bottom have longer lengths. The ends of the multiple heat pipes 383 away from the heat spreader 382 are fixed to a copper plate 384. The copper plate 384 is fixed to the outer circle of the cold flow pipe 37 and is also fixed to the inner wall of the base 21, so that the structure of the copper plate 384 remains stable. Half of the outer circle of the cold flow pipe 37 is fixed to the base 21 and the other half is fixed to the copper plate 384 to better absorb the heat on the copper plate 384. The heat conduction assembly 38 also includes a support 385, which is fixed to the bottom of the multiple heat pipes 383. The support 385 is used to support the multiple heat pipes 383 and is fixed to the bottom wall of the heat conduction chamber 23.

[0031] Please see Figure 6Each heat conduction chamber 23 has three units, each set of cold flow pipes 37 and each set of heat conduction components 38 have three units. Each set of cold flow pipes 37 and each set of heat conduction components 38 are arranged in a heat conduction chamber 23. The multiple sets of cold flow pipes 37 are arranged horizontally and are arranged around the outer circle of the injection molding tank 22, so that the multiple sets of cold flow pipes 37 can absorb heat from the outer circle of the injection molding tank 22. The multiple heat pipes 383 in each heat conduction chamber 23 are evenly distributed. Multiple refrigerant output pipes 39 are connected to the multiple sets of cold flow pipes 37 respectively. The multiple refrigerant output pipes 39 are arranged above the waste liquid pool 32, so as to discharge the waste liquid that has absorbed heat into the waste liquid pool 32. In this embodiment, the refrigerant is water and ethylene glycol-based liquid.

[0032] Please refer to the following: Figures 1 to 6 In this invention, refrigerant is injected into a refrigerant pool 31, followed by molten material injected into an injection molding tank 22. This drives a pump 33 to operate, and the refrigerant is drawn out through a delivery pipe 34. The refrigerant is then distributed through multiple diversion pipes 35 to multiple sets of refrigerant input pipes 36. Subsequently, the heat at different depths within the injection molding tank 22 is absorbed through the flow of multiple sets of cold flow pipes 37. Since the heat tends to accumulate at the top of the injection molding tank 22, the uppermost cold flow pipe 37 is closest to the pump 33, allowing for faster heat absorption. The heat within the injection molding tank 22 is conducted to the cold flow pipes 37 via copper sheet 381, heat spreader 382, ​​heat pipe 383, and copper plate 384. The heat is ultimately absorbed by the refrigerant within the cold flow pipes 37 and released through multiple refrigerant output pipes 39, thus completing heat conduction and achieving rapid heat dissipation. This process is beneficial for the efficient molding of the aromatherapy diffuser base.

[0033] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
