Description

Technical Field

[0001] The invention relates to the technical field of aluminum alloy casting, in particular to a cooling device for casting an aluminum alloy connecting piece. Background Art

[0002] The casting of aluminum alloy workpieces is to inject high-temperature and high-pressure liquid metal into a mold, and then cool the liquid metal through a cooling device to obtain a workpiece of the desired shape. Aluminum alloy castings have the advantages of stable quality and good mechanical properties. Most of the current cooling devices circulate the coolant through the mold through a circulating pump, and then take away the heat from the aluminum alloy casting to achieve a cooling effect. This cooling method not only consumes electricity, but also consumes water resources.

[0003] Chinese patent CN116833396B discloses a motor housing casting device and a casting method thereof, including a casting device, a demoulding assembly is installed on the side of the casting device, a liquid injection assembly is installed on the side of the demoulding assembly, a fixed mold assembly is installed on both sides of the casting device, a cooling assembly is installed on the top of the casting device, and a first hydraulic cylinder is installed on the top of the demoulding assembly. The motor housing casting device uses a first hydraulic cylinder to control the first telescopic rod to press down, thereby driving the first spring to be sleeved into the inner side of the upper mold, and to push out the cast motor housing, and the second hydraulic cylinder controls the second telescopic rod to rise at the bottom, driving the second sleeve to push out the housing part inside the lower mold, so that the motor housing can be quickly separated after production is completed through two-way pushing, and the rebound force of the first spring and the second spring can assist in improving the pushing effect, and at the same time facilitate the later reset processing.

[0004] The above-mentioned prior art discloses a motor casing casting device and a casting method thereof, wherein a cooling component is used to spray coolant on a casting mold, thereby efficiently cooling the casting mold and rapidly solidifying the casting liquid. However, after multiple castings and cooling, metal debris will remain in the inner cavity of the casting mold. If it is not cleaned, it will affect the next casting. In addition, during the casting process of aluminum alloys, the temperature of the casting mold is generally maintained within the range of 150°C-200°C. During the cooling process of the aluminum alloy casting, the temperature of the casting mold will also drop, which will affect the quality of the next casting. If the casting mold is preheated again, it will not only be time-consuming but also power-consuming. In addition, the general coolant circulation is pressurized by a circulating pump, and the heat generated during the casting process cannot be used to circulate the coolant.

[0005] In view of the above problems, a cooling device for casting aluminum alloy connecting parts is proposed. Summary of the invention

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] In order to solve the technical problem that the temperature of the casting mold 9 decreases during the cooling process of the aluminum alloy casting, which will affect the quality of the next casting workpiece, if the casting mold 9 is preheated again, it will not only be time-consuming but also power-consuming. Figure 1-Figure 5 , Figure 7-10 and Fig.12 As shown, the following preferred technical solutions are provided:

[0038] A cooling device for casting aluminum alloy connecting parts comprises a base 1 and a support frame 2 fixedly mounted on the top surface of the base 1. The base 1 is arranged to support and fix many parts. A plurality of support columns 3 are fixedly mounted on the top surface of the base 1. A load-bearing plate 4 is fixedly connected to the top surfaces of the plurality of support columns 3. A down-pressing component 5 is fixedly mounted through the middle of the top surface of the load-bearing plate 4. The purpose of the load-bearing plate 4 is to support and limit the down-pressing component 5. The moving end of the down-pressing component 5 is slidably sleeved on the outer peripheral walls of the plurality of support columns 3. An upper mold 6 is fixedly mounted on the middle of the bottom surface of the down-pressing component 5. Through such an arrangement, the down-pressing component 5 can slide stably in the vertical direction, and the upper mold 6 can further slide on a preset track, thereby reducing the probability of position displacement of the down-pressing component 5 and the upper mold 6 during sliding, which is beneficial to improving the casting quality of the aluminum alloy workpiece.

[0039] A first outer mold 7 and a second outer mold 8 are slidably mounted on the top surface of the support frame 2, respectively. The first outer mold 7 and the second outer mold 8 are symmetrically arranged. A casting mold 9 is also arranged on the top surface of the support frame 2, and the first outer mold 7 and the second outer mold 8 are respectively arranged on both sides of the casting mold 9. A pair of bidirectional telescopic components 30 are fixedly mounted on the top surface of the support frame 2, and the two telescopic ends of the bidirectional telescopic components 30 are respectively fixedly mounted on the side walls of the first outer mold 7 and the second outer mold 8. The bidirectional telescopic components 30 can drive the first outer mold 7 and the second outer mold 8 to slide synchronously in opposite directions. A first evaporation chamber 10 is fixedly mounted on the outer side wall of the first outer mold 7, and steam is generated by utilizing the heat during the casting process. The first evaporation chamber 10 and the two bidirectional telescopic components 30 are connected by pipelines 100, respectively. Steam enters the bidirectional telescopic components 30 through the pipelines 100, which can drive the bidirectional telescopic components 30 to operate. A second evaporation chamber 20 is fixedly mounted on the outer side wall of the second outer mold 8, and steam is also generated by utilizing the heat during the casting process.

[0040] The first electronic valve 40 and the second electronic valve 50 are fixedly installed on the top surface of the support frame 2, and the first condenser 60, the second condenser 70, the first liquid storage chamber 80 and the second liquid storage chamber 90 are fixedly installed on the top surface of the base 1, the second evaporation chamber 20 is connected to the first liquid storage chamber 80 and the second liquid storage chamber 90 through the pipeline 100, and the two two-way telescopic components 30 are connected to the first condenser 60 and the second condenser 70 through the pipeline 100 respectively, and the first liquid storage chamber 80, the first condenser 60, the first electronic valve 40, the casting mold 9, the second electronic valve 50, the second condenser 70 and the second liquid storage chamber 90 are connected in sequence through the pipeline 100.

[0041] The support frame 2 includes a base 21 fixedly mounted on the top surface of the base 1, and a first slide groove 22 and a second slide groove 23 are respectively opened on the top surface of the base 21.

The first outer mold 7 is embedded and slidably installed in the inner cavity of the first slide groove 22, and the second outer mold 8 is embedded and slidably installed in the inner cavity of the second slide groove 23.

[0042] The base 21 includes a base body 211 , and a through slot 212 is formed in the base body 211 .

[0043] The pressing assembly 5 includes an electric telescopic column 51 which is fixedly installed through the middle of the top surface of the load-bearing plate 4 and a moving part 52 which is fixedly installed at the lower end of the electric telescopic column 51. The moving part 52 is slidably mounted on the outer peripheral walls of several support columns 3. Such an arrangement enables the moving part 52 to slide stably in the vertical direction.

[0044] The upper mold 6 includes an upper mold body 61 fixedly mounted at the middle of the bottom surface of the moving part 52. A pouring port 62 is provided on the upper mold body 61. During the casting process of the aluminum alloy workpiece, the electric telescopic column 51 drives the upper mold body 61 to press on the casting mold 9 through the moving part 52, and then the high-temperature liquid metal is poured into the casting mold 9 from the pouring port 62 for molding.

[0045] The first evaporation chamber 10 includes an evaporation chamber body 101 fixedly mounted on the outer side wall of the first outer mold 7, and a first electronic gas valve 102 and a second electronic gas valve 103 are respectively connected to the side walls at both ends of the evaporation chamber body 101. The first electronic gas valve 102 and the second electronic gas valve 103 are respectively connected to two two-way telescopic components 30 through pipelines 100. The steam in the evaporation chamber body 101 enters the inner cavities of the two two-way telescopic components 30 through pipelines 100, driving the two two-way telescopic components 30 to operate synchronously.

[0046] The bidirectional telescopic assembly 30 includes a shell 301 fixedly mounted on the top surface of the base body 211, wherein a first chamber 302 and two second chambers 306 are respectively arranged inside the shell 301, and the two second chambers 306 are respectively arranged on both sides of the first chamber 302, and sliding rods 307 are respectively slidably installed in the inner cavities of the two second chambers 306, and the sliding rods 307 and the corresponding second chambers 306 are elastically arranged by springs 309, and connecting rods 308 are respectively fixedly mounted on the inner side walls of the two sliding rods 307, and one of the two connecting rods 308 is fixedly connected to the side wall of the first outer mold 7, and the other is fixedly connected to the side wall of the second outer mold 8. Fixedly connected, air holes 305 are respectively opened on the inner walls on both sides of the inner cavity of the first chamber 302, and the air holes 305 are connected to the corresponding second chamber 306. An air intake valve 303 is arranged on the side wall of the shell 301, and the air intake valve 303 is connected to the first chamber 302, and the air intake valve 303 on the two two-way telescopic components 30 are connected to the first electronic gas valve 102 and the second electronic gas valve 103 respectively through the pipeline 100, and a pressure relief valve 304 is arranged on the top surface of the shell 301, and the pressure relief valves 304 on the two two-way telescopic components 30 are connected to the first condenser 60 and the second condenser 70 respectively through the pipeline 100.

[0047] Specifically, during the casting process, the electric telescopic column 51 is started, the upper mold body 61 is pressed onto the casting mold 9, and then liquid metal is injected into the casting mold 9 from the filling port 62. The heat of the liquid metal will be conducted to the inner cavities of the first evaporation chamber 10 and the second evaporation chamber 20 through the casting mold 9, the first outer mold 7 and the second outer mold 8, respectively, so that the water in the first evaporation chamber 10 and the second evaporation chamber 20 is converted into water vapor, and the generated steam is temporarily stored in the inner cavities of the first evaporation chamber 10 and the second evaporation chamber 20.

[0048] Furthermore, the steam in the evaporation chamber body 101 will pass through the first electronic gas valve 102, the second electronic gas valve 103, the pipeline 100 and the air inlet valve 303, and enter the inner cavity of the two first chambers 302 respectively, and then enter the inner cavity of the second chamber 306 respectively through the air hole 305. When the steam pressure is greater than the elastic force of the spring 309, it will push the two sliding rods 307 and the connecting rod 308 to slide in the opposite direction in the inner cavity of the two second chambers 306, so that the first outer mold 7 and the second outer mold 8 move in opposite directions on the top surface of the base 21 and separate from the casting mold 9. At this time, the high-temperature and high-pressure steam in the inner cavity of the second evaporation chamber 20 enters the inner cavity of the first liquid storage chamber 80 through the pipeline 100. The water in the inner cavity of the first liquid storage chamber 80 is heated and pressurized in the cavity. After the water in the inner cavity of the first liquid storage chamber 80 is pressurized, it will flow through the casting mold 9 through the pipe 100, take away the heat on the casting mold 9, and then enter the second condenser 70 through the pipe 100 for condensation. The condensed water will enter the second liquid storage chamber 90 through the pipe 100 for storage. When the cooling is completed, the steam in the inner cavity of the first chamber 302 and the second chamber 306 is released to the first condenser 60 and the second condenser 70 through the pipe 100 for condensation. The condensed water will flow into the first liquid storage chamber 80 and the second liquid storage chamber 90 through the pipe 100 for circulating cooling, thereby improving the utilization rate of water resources.

[0049] Furthermore, under the elastic force of the spring 309, the sliding rod 307 and the connecting rod 308 will respectively drive the first outer mold 7 and the second outer mold 8 to move synchronously in the direction close to the casting mold 9 until the first outer mold 7 and the second outer mold 8 are in contact with the casting mold 9, and then the electric telescopic column 51 drives the upper mold body 61 to reset upward, and the operator can take out the aluminum alloy casting in the casting mold 9. At this time, the first outer mold 7 and the second outer mold 8 still have a relatively high temperature, which can preheat the casting mold 9 to prevent affecting the quality of the next casting. Through the above-mentioned arrangement, without affecting the cooling of the aluminum alloy casting, the residual temperature of the first outer mold 7 and the second outer mold 8 can also be used to preheat the casting mold 9, which not only improves the utilization rate of heat, but also is beneficial to subsequent casting operations, and reduces the probability of affecting subsequent casting due to the excessively low temperature of the casting mold 9.

[0050] In order to solve the technical problem that metal debris will remain in the inner cavity of the casting mold 9 during the cooling process of the aluminum alloy casting, affecting the next casting, such as Figure 1 , Figure 3-Figure 5 , Figure 7-Figure 8 and Figure 10-13 As shown, the following preferred technical solutions are provided:

[0051] The first outer mold 7 includes an outer mold body 71 embedded and slidably installed in the inner cavity of the first slide groove 22, and a first rack 72 is fixedly installed on the side wall of the outer mold body 71 opposite to the second outer mold 8, and a first insertion hole 73 is also opened on the side wall of the outer mold body 71 opposite to the second outer mold 8.

[0052] The second outer mold 8 includes an outer mold body 81 embedded and slidably installed in the inner cavity of the second slide groove 23, and a second rack 82 is fixedly installed on the side wall of the outer mold body 81 opposite to the outer mold body 71. A second plug hole 83 is also provided on the side wall of the outer mold body 81 opposite to the outer mold body 71. The setting of the first plug hole 73 enables the second rack 82 to be inserted into the first plug hole 73 when the outer mold body 81 and the outer mold body 71 are close to each other, and thus will not cause obstruction to the relative movement of the outer mold body 81 and the outer mold body 71. The second plug hole 83 enables the first rack 72 to be inserted into the second plug hole 83, also to avoid obstructing the relative movement between the outer mold body 81 and the outer mold body 71.

[0053] The casting mold 9 includes a pair of fixed rods 91 fixedly installed on the top surface of the base body 211, and ratchet gears 92 are fixedly installed on the inner side walls of the two fixed rods 91 respectively. The inner side walls of the two ratchet gears 92 are commonly fixedly connected with an inner mold 93, and the two ratchet gears 92 are meshedly connected with the first rack 72 and the second rack 82 respectively.

[0054] Specifically, when the outer mold body 1 71 and the outer mold body 2 81 move in opposite directions on the top surface of the base body 211 and separate from the inner mold 93, due to the action of the ratchet gear 92, the first rack 72 and the second rack 82 will not drive the inner mold 93 to flip over, and thus will not overturn the aluminum alloy casting in the inner mold 93. When the cooling work is completed, when the two-way telescopic component 30 drives the outer mold body 1 71 and the outer mold body 2 81 to move synchronously in the direction close to the inner mold 93, the first rack 72 and the second rack 82 drive the ratchet gear 92 to rotate, thereby driving the inner mold 93 to flip over on the fixed rod 91, pouring out the metal debris generated in the inner cavity of the inner mold 93 to prevent affecting the next casting. When the outer mold body 1 71 and the outer mold body 2 81 are completely reset, the inner mold 93 is just opened upward, and the inner mold 93 is in contact with the outer mold body 1 71 and the outer mold body 2 81, which does not affect the subsequent casting and heat conduction.

[0055] In order to solve the technical problem that the heat in the casting process cannot be used for coolant circulation, such as Figure 1 , Figure 5-Figure 6 , Figure 8 , Fig.10 and Fig.12 As shown, the following preferred technical solutions are provided:

[0056] The second evaporation chamber 20 includes an evaporation chamber body 201 fixedly mounted on the outer side wall of the outer mold body 81, and a third electronic gas valve 202 and a fourth electronic gas valve 203 are respectively connected and arranged on the top surface of the evaporation chamber body 201. The third electronic gas valve 202 is connected to the first liquid storage chamber 80 via a pipeline 100, and the fourth electronic gas valve 203 is connected to the second liquid storage chamber 90 via a pipeline 100.

[0057] The second electronic valve 50 includes a valve body 501 fixedly mounted on the top surface of the base body 211, and a first channel 502, a second channel 503 and a third channel 504 are respectively arranged on the valve body 501. The first channel 502 is connected to the inner mold 93 through a pipe 100, the second channel 503 is connected to the second condenser 70 through a pipe 100, and the third channel 504 is connected to the second liquid storage chamber 90 through a pipe 100. The composition structure and connection method of the first electronic valve 40 and the second electronic valve 50 are consistent.

[0058] The second liquid storage chamber 90 includes a liquid storage tank 901 fixedly installed on the top surface of the base 1 and a one-way air valve 902 connected and fixedly installed on the top surface of the liquid storage tank 901. The one-way air valve 902 and the fourth electronic air valve 203 are connected by a pipeline 100. A water valve 903 is connected on the side wall of the liquid storage tank 901. The water valve 903 and the third channel 504 are connected by a pipeline 100. The composition structure and connection method of the second liquid storage chamber 90 are consistent with those of the first liquid storage chamber 80.

[0059] Specifically, when cooling the aluminum alloy casting, the high-temperature and high-pressure steam in the inner cavity of the evaporation chamber main body 201 enters the inner cavity of the first liquid storage chamber 80 through the third electronic gas valve 202 and the pipeline 100 to heat and pressurize the water in the inner cavity of the first liquid storage chamber 80. After the water in the inner cavity of the first liquid storage chamber 80 is pressurized, it will flow through the inner mold 93 through the pipeline 100, take away the heat on the inner mold 93, and then enter the valve body 501 through the pipeline 100 and the first channel 502, and then enter the second condenser 70 through the second channel 503 and the pipeline 100 for condensation. The condensed water will enter the liquid storage tank 901 through the pipeline 100 for the next cycle cooling.

[0060] Furthermore, when the next cooling is performed, the high-temperature and high-pressure steam in the inner cavity of the evaporation chamber main body 201 enters the liquid storage tank 901 through the fourth electronic gas valve 203, the pipeline 100 and the one-way gas valve 902, and the water in the inner cavity of the liquid storage tank 901 is heated and pressurized. The pressurized water will enter the inner cavity of the valve body 501 through the water valve 903, the pipeline 100 and the third channel 504, and then flow through the inner mold 93 through the first channel 502 and the pipeline 100, taking away the heat on the inner mold 93, and then enter the first condenser 60 through the pipeline 100 and the first electronic valve 40 for condensation. The condensed water will enter the first liquid storage chamber 80 through the pipeline 100 for storage, which is convenient for subsequent circulating cooling. In this way, circulating cooling can be formed, and circulating cooling can be achieved by utilizing the heat in the casting process. The purpose of heating water with steam is to make the temperature of the cooling water higher than the room temperature, so that no condensation will appear on the casting mold 9 and the aluminum alloy casting during the cooling process, which is beneficial to improving the quality of the aluminum alloy casting.
