Description

Technical Field

[0001] The invention belongs to the technical field of mold temperature control, in particular to a temperature control device for a die-casting mold. Background Art

[0002] The mold temperature controller is a temperature control device used for die-casting molds. It mainly achieves precise control of the mold temperature through the circulation of heating or cooling media.

[0003] The mold temperature controller is connected to the pipelines on the die-casting mold through the oil return pipeline and the oil delivery pipeline. Its principle is to pump the heated oil into the internal pipeline of the mold through the heat transfer oil circulation system, and use heat exchange to preheat or cool the mold, thereby avoiding sticking or dimensional deviation caused by high temperature, reducing mold thermal stress shock, and preventing mold cracking or premature aging.

[0004] For example, the invention patent with the announcement number CN105818348B discloses a mold temperature control device including a gas storage tank, a heating tank and a heat exchanger. The aforementioned gas storage tank is provided with a steam output air pipe, the aforementioned heating tank has a water inlet and a built-in heating pipe, the aforementioned heating tank is connected to the gas storage tank through a gas pipe, the aforementioned heat exchanger has a cold water inlet, a hot water outlet, a steam recovery port and a condensed water outlet, and the hot water outlet is connected to the water inlet of the aforementioned heating tank. It is characterized in that: the gas storage tank and the heating tank are both strip-shaped and arranged up and down at intervals, and the gas pipes are at least three, which are arranged at both ends and the middle of the gas storage tank. Compared with the prior art, the advantage of the present invention is that the multi-channel design can make the whole of the heating tank enter the gas storage tank in sufficient quantity at the same time, so that the steam saturation output from the gas storage tank is relatively high, thereby ensuring the heat transfer effect of the output steam. In the above scheme, the temperature of saturated steam is determined by its pressure, but in actual application, if the steam contains water or local overheating occurs, it will cause temperature fluctuations.

[0005] Another example is the invention of enhanced polypropylene engineering plastic processing equipment and its preparation method with publication number CN119773163A. The enhanced polypropylene engineering plastic processing equipment and its preparation method include a screw extruder, a feeding mechanism located at the top of the screw extruder, a heat conduction mechanism located outside the screw extruder, an upper mold body and a lower mold body located at the output end of the screw extruder, the upper mold body and the lower mold body are combined, and a mold support frame is supported at the bottom end of the lower mold body, and the bottom end of the mold support frame is fixedly connected to a base; the heat conduction mechanism includes a heat pipe body and a cold pipe body, and the heat pipe body is filled with heat conduction oil, and the cold pipe body is filled with coolant, and a plurality of hollow heat conduction blocks are connected between the heat pipe body and the cold pipe body at the same time. The enhanced polypropylene engineering plastic processing equipment and its preparation method disclosed in the present invention have the advantages of ensuring the melting requirements, fluidity, miscibility and finished product quality of the raw materials during the feeding process, while playing a role in saving costs. In addition, it also avoids the cooling of the mold during the cooling process, and provides effective protection for the mold. However, when the mold temperature is too high, the oil temperature will rise rapidly inside the mold, causing local gasification of the oil to produce bubbles. These bubbles will act like a heat-insulating layer and hinder the heat conduction between the mold and the heat-conducting oil, thereby reducing the heat exchange effect between the oil and the inner wall of the mold, and causing the mold's local temperature to be too high or too low to increase. And when the bubbles flow into narrow pipes or pumps with the oil, it will cause a sudden change in local pressure, and cause additional impact on the pump and other equipment, shortening its service life.

[0006] Based on this, in order to solve the above problems, a die-casting mold temperature control device is proposed. Summary of the invention

The bottom end of the defoaming slurry mechanism is located above the liquid surface of the heat transfer oil in the liquid collecting cylinder and can be telescopically adjusted with the liquid level. Fan blades are also arranged on the periphery of the defoaming slurry mechanism. When the heat transfer oil in the oil return pipe is output, it can impact the fan blades and drive the defoaming slurry mechanism to rotate.

[0009] Preferably, the top of the separation tank is fixedly connected to a condensing mechanism for collecting and condensing the gas in the separation tank and then returning it to the separation tank. Preferably, the drainage temperature control mechanism includes a pump body, whose input end is connected to the bottom of the liquid collecting barrel, and the output end of the pump body is fixedly connected to an electrically controlled three-way valve, and the two output ends of the electrically controlled three-way valve are respectively connected to the heating chamber and the cooling chamber, and the output ends of the two are connected to the same drainage pipe.

[0010] Preferably, the defoaming slurry mechanism comprises a main shaft movably connected to the oil return pipe, a spline shaft is splined in the main shaft, a cavity is opened at the bottom end of the spline shaft, a crushing blade is fixedly connected to the bottom end of the spline shaft, and an adjustment component for reducing the pressure of the spline shaft on the liquid surface of the liquid collecting cylinder is symmetrically arranged in the main shaft; The bottom end of the spline shaft extends into the liquid surface of the liquid collecting barrel and is subjected to the buoyancy of the liquid so that the crushing blades are located above the liquid surface.

[0011] Preferably, the adjustment assembly comprises a gear movably connected to the inside of the main shaft, and a round rack meshing with the gear is also vertically movably connected inside the main shaft; A plurality of groups of ring teeth that can mesh with gears are vertically arranged in the middle of the spline shaft.

[0012] Preferably, a conical dispersion plate located below the conical porous plate is fixedly connected to the outer periphery of the main shaft.

[0013] Preferably, a funnel located between the crushing blades and the conical dispersion plate is fixedly connected inside the separation tank, and a gap is left between the funnel and the outer wall of the spline shaft.

[0014] Preferably, the condensation mechanism includes a condensation box located above the separation tank, the top of the separation tank is fixedly connected to an exhaust pipe, and the top of the exhaust pipe is connected to the condensation box, cooling fins are also provided in the condensation box, the bottom of the condensation box is fixedly connected to a liquid return pipe, the bottom end of the liquid return pipe is connected to the middle of the separation tank, and a pressure relief valve is also provided on the top of the condensation box.

[0015] Preferably, the bottom of the condensation tank is an inclined surface, and the bottom of the inclined surface is connected to the liquid return pipe. Preferably, the bottom end of the liquid return pipe is V-shaped.

[0016] Compared with the prior art, the present invention has the following beneficial effects: The above scheme allows the heat transfer oil to enter the oil return pipe and squeeze the tension spring baffle to move downward. At this time, the heat transfer oil will form a conical heat transfer oil film through the inner wall of the output end of the oil return pipe and the outer wall of the tension spring baffle to enter the separation tank and impact the fan blades, causing it to drive the defoaming slurry mechanism to rotate and separate the heat transfer oil film. The dispersed heat transfer oil will fall on the conical porous plate and fall into the liquid collecting cylinder through the guidance of the conical porous plate. In the above process, the heat transfer oil will release a large amount of heat and the gas inside it due to being dispersed. At the same time, the ultrasonic generator is running to discharge the gas inside the heat transfer oil in the liquid collecting cylinder to make it float. At the same time, the bubbles floating on the liquid surface at the top of the liquid collecting cylinder are broken by the rotation of the bottom end of the defoaming slurry mechanism. Finally, the heat transfer oil is heated or cooled by the liquid discharge temperature control mechanism and then re-input into the die-casting mold for temperature control, thereby avoiding the bubbles in the heat transfer oil from affecting the mold. In the above scheme, when the heat transfer oil impacts the fan blades, the main shaft and the spline shaft will be driven to rotate, thereby rotating the crushing blades. At the same time, under the buoyancy of the cavity and the balancing force of the adjustment component, the crushing blades will be able to fit the liquid surface of the heat transfer oil in the liquid collecting cylinder, ensuring that when the oil input volume of the return oil pipe and the oil output volume of the discharge temperature control mechanism change, the crushing blades can adapt to the changes in the liquid surface in the liquid collecting cylinder and can continue to crush the bubbles floating in the heat transfer oil on the liquid collecting cylinder; The above scheme guides the heat transfer oil to the top of the crushing blade through the funnel and flows down along the conical surface on it, thereby driving the bubbles floating in the middle of the liquid collecting cylinder from the center to the outside. Since the speed of the end of the crushing blade is faster, the crushing blade can have a better effect on the crushing of bubbles. The above scheme can store part of the cooled heat transfer oil in the bent part of the return liquid pipe, thereby forming a communicating vessel structure, ensuring that the condensed liquid in the condensation tank can enter the separation tank through the return liquid pipe, and at the same time can prevent the gas in the separation tank from entering the condensation tank through the return liquid pipe to ensure that the gas and liquid pipelines can work separately and avoid mutual interference.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. 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.

[0029] like Figures 1 to 10 As shown, the present invention provides a temperature control device for a die casting mold, comprising a separation tank 1, an oil return pipe 2 and a liquid discharge temperature control mechanism 3, the oil return pipe 2 and the liquid discharge temperature control mechanism 3 are both installed with a temperature sensor 21, the output end of the oil return pipe 2 is connected to the upper part of the separation tank 1, a conical porous plate 12 is fixedly connected to the middle part of the separation tank 1, and a gap is left between the outer periphery of the conical porous plate 12 and the inner wall of the separation tank 1, a liquid collecting cylinder 11 for receiving the heat transfer oil output by the oil return pipe 2 is arranged at the bottom of the separation tank 1, and the input end of the liquid discharge temperature control mechanism 3 is connected to the bottom of the liquid collecting cylinder 11; A baffle 22 is fixedly connected to the bottom of the oil return pipe 2. A tension spring baffle 24 is provided on the oil return pipe 2 to block the output end of the oil return pipe 2 in the initial state. An air hole 23 is opened on the top of the oil return pipe 2. An ultrasonic generator 4 is fixedly connected to the separation tank 1, and its generating end extends to the inside of the liquid collecting cylinder 11; A defoaming slurry mechanism 6 located inside the separation tank 1 is movably mounted on the oil return pipe 2. The bottom end of the defoaming slurry mechanism 6 is located above the liquid surface of the heat transfer oil in the liquid collecting cylinder 11 and can be adjusted to extend and contract with the height of the liquid surface. Fan blades 7 are also arranged on the periphery of the defoaming slurry mechanism 6. When the heat transfer oil in the oil return pipe 2 is output, it can impact the fan blades 7 and drive the defoaming slurry mechanism 6 to rotate. The top of the separation tank 1 is fixedly connected to a condensation mechanism 5 for collecting and condensing the gas in the separation tank 1 and then reflowing it into the separation tank 1; By adopting the above scheme, the heat transfer oil enters the return oil pipe 2 and squeezes the tension spring baffle 24 downward. At this time, the heat transfer oil will form a conical heat transfer oil film through the inner wall of the output end of the return oil pipe 2 and the outer wall of the tension spring baffle 24 to enter the separation tank 1, and impact the fan blades 7, so that it drives the defoaming slurry mechanism 6 to rotate and separate the heat transfer oil film. The dispersed heat transfer oil will fall on the conical porous plate 12 and fall into the liquid collecting cylinder 11 through the guidance of the conical porous plate 12. In the above process, the heat transfer oil will release a large amount of heat and the gas inside it due to being dispersed. At the same time, the ultrasonic generator 4 is running to discharge the gas inside the heat transfer oil in the liquid collecting cylinder 11 to make it float. At the same time, the bubbles floating on the liquid surface at the top of the liquid collecting cylinder 11 are broken by the rotation of the bottom end of the defoaming slurry mechanism 6. Finally, the heat transfer oil is heated or cooled by the liquid discharge temperature control mechanism 3 and then re-input into the die-casting mold for temperature control, thereby avoiding the bubbles in the heat transfer oil from affecting the mold.

[0030] like Figure 1 and Figure 2 As shown, the liquid discharge temperature control mechanism 3 includes a pump body 31, whose input end is connected to the bottom of the liquid collecting cylinder 11, and the output end of the pump body 31 is fixedly connected to an electric-controlled three-way valve 32, and the two output ends of the electric-controlled three-way valve 32 are respectively connected to a heating chamber 33 and a cooling chamber 34, and the output ends of the two are connected to the same liquid discharge pipe 35; By adopting the above scheme, the temperature sensor 21 on the return oil pipe 2 can detect the temperature of the returning heat transfer oil and determine whether the temperature in the die-casting mold is too high, thereby controlling the electric three-way valve 32 to connect with the heating chamber 33 or the cooling chamber 34, and finally inputting the cooled or heated heat transfer oil into the mold through the drain pipe 35.

[0031] like Figure 2-Figure 10 As shown, the defoaming pulp mechanism 6 includes a main shaft 61 movably connected to the oil return pipe 2, a spline shaft 63 is splined in the main shaft 61, a cavity 631 is opened at the bottom end of the spline shaft 63, a crushing blade 62 is fixedly connected to the bottom end of the spline shaft 63, and an adjustment component 64 for reducing the liquid surface pressure of the spline shaft 63 on the liquid collecting cylinder 11 is symmetrically arranged in the main shaft 61; The bottom end of the spline shaft 63 extends to the liquid surface of the liquid collecting cylinder 11 and the buoyancy of the liquid enables the crushing blade 62 to be above the liquid surface; The adjustment assembly 64 includes a gear 641 movably connected to the inside of the main shaft 61, and a round rack 642 meshing with the gear 641 is also vertically movably connected inside the main shaft 61; A plurality of groups of ring teeth capable of meshing with the gear 641 are vertically arranged in the middle of the spline shaft 63; By adopting the above scheme, when the heat transfer oil impacts the fan blade 7, the main shaft 61 and the spline shaft 63 are driven to rotate, thereby rotating the crushing blade 62. At the same time, under the buoyancy of the cavity 631 and the balancing force of the adjustment component 64, the crushing blade 62 can be close to the liquid surface of the heat transfer oil in the liquid collecting barrel 11, ensuring that when the oil input amount of the return oil pipe 2 and the oil output amount of the discharge temperature control mechanism 3 change, the crushing blade 62 can adapt to the change of the liquid surface in the liquid collecting barrel 11 and can continue to crush the bubbles floating in the heat transfer oil on the liquid collecting barrel 11; It is worth noting that the round rack 642 has a downward trend due to its own gravity, and the meshing of the gear 641 and the spline shaft 63 can reduce the buoyancy of the spline shaft 63, so as to avoid the situation where the spline shaft 63 has too much gravity and the cavity 631 cannot provide sufficient buoyancy, resulting in the liquid surface flow and the mixing of bubbles when the crushing blade 62 rotates deep into the liquid surface; and because the bottom of the spline shaft 63 is cylindrical, and the cavity 631 is the part opened at the bottom of the spline shaft 63, when the main shaft 61 rotates to drive the spline When the shaft 63 rotates, the bottom of the spline shaft 63 will also rotate in the heat transfer oil portion stored in the liquid collecting barrel 11. Since the top section of the spline shaft 63 is a smooth circle, and the projection of the spline shaft 63 in the vertical direction is the center of the liquid collecting barrel 11, when the spline shaft 63 rotates, the influence of the spline shaft 63 on the heat transfer oil liquid level in the liquid collecting barrel 11 can be ignored, thereby avoiding the situation where the spline shaft 63 rotates and causes the liquid surface in the liquid collecting barrel 11 to generate a vortex, thereby affecting the bubble breaking effect of the breaking blade 62.

[0032] like Figure 6-Figure 8 As shown, the outer periphery of the main shaft 61 is fixedly connected with a conical dispersion plate 611 located below the conical porous plate 12; the interior of the separation tank 1 is also fixedly connected with a funnel 13 located between the crushing blade 62 and the conical dispersion plate 611, and a gap is left between the funnel 13 and the outer wall of the spline shaft 63; By adopting the above scheme, the heat transfer oil is guided to the top of the crushing blade 62 through the funnel 13 and flows down along the conical surface thereon, thereby driving the bubbles floating in the middle of the liquid collecting cylinder 11 from the center to the outside. Since the speed of the end of the crushing blade 62 is faster, the crushing blade 62 can have a better effect on crushing the bubbles.

[0033] like Figure 1 , Figure 2 and Figure 4As shown, the condensation mechanism 5 includes a condensation box 51 located above the separation tank 1, the top of the separation tank 1 is fixedly connected with an exhaust pipe 55, and the top of the exhaust pipe 55 is connected with the condensation box 51, and a heat dissipation fin 52 is also arranged in the condensation box 51, the bottom of the condensation box 51 is an inclined surface, and the bottom of the inclined surface is fixedly connected with a liquid return pipe 53, the bottom end of the liquid return pipe 53 is connected with the middle part of the separation tank 1, and a pressure relief valve 54 is also arranged on the top of the condensation box 51; the bottom end of the liquid return pipe 53 is V-shaped; By adopting the above scheme, after the hot gas in the heat transfer oil is separated, it will enter the condensation box 51 through the exhaust pipe 55 and be cooled by the heat dissipation fins 52. At this time, the condensed liquid droplets generated by the cooling will flow back to the separation tank 1 through the condensation box 51 and the return pipe 53 for circulation, thereby avoiding the situation where part of the heat transfer oil is gasified and discharged and wasted. At the same time, through the V-shaped bending arrangement at the bottom of the return pipe 53, part of the cooled heat transfer oil can be stored in the bending part of the return pipe 53, thereby forming a communicating vessel structure, ensuring that the condensed liquid in the condensation box 51 can enter the separation tank 1 through the return pipe 53, and at the same time, it can prevent the gas in the separation tank 1 from entering the condensation box 51 through the return pipe 53 to ensure that the gas and liquid pipelines can work separately and avoid mutual interference.

[0034] The working principle and use process of the present invention: The heat-conducting oil in the die-casting mold passes through the return oil pipe 2 and squeezes the tension spring baffle 24 to go downward. At this time, the heat-conducting oil will form a conical heat-conducting oil film through the inner wall of the output end of the return oil pipe 2 and the outer wall of the tension spring baffle 24 to enter the separation tank 1, and impact the fan blades 7, so that it drives the defoaming slurry mechanism 6 to rotate and separate the heat-conducting oil film. The dispersed heat-conducting oil will fall on the conical porous plate 12 and fall into the liquid collecting cylinder 11 through the guidance of the conical porous plate 12. In the above process, the heat-conducting oil will release a large amount of heat and the gas inside it due to being dispersed. At the same time, the ultrasonic generator 4 is running to discharge the gas inside the heat-conducting oil in the liquid collecting cylinder 11 to make it float. At the same time, the bubbles floating on the top liquid surface of the liquid collecting cylinder 11 are broken by the rotation of the bottom end of the defoaming slurry mechanism 6. Finally, the heat-conducting oil is heated or cooled by the liquid discharge temperature control mechanism 3 and then re-input into the die-casting mold for temperature control; When the fan blade 7 rotates, the fan blade 7 will drive the spline shaft 63 to rotate through the main shaft 61, thereby causing the crushing blade 62 to rotate. At the same time, under the buoyancy of the cavity 631 and the balancing force of the adjustment component 64, the crushing blade 62 will be able to fit the liquid level of the heat transfer oil in the liquid collecting barrel 11, ensuring that when the oil input amount of the return oil pipe 2 and the oil output amount of the discharge temperature control mechanism 3 change, the crushing blade 62 can adapt to the change of the liquid level in the liquid collecting barrel 11; at the same time, the setting of the funnel 13 guides the heat transfer oil to the conical surface at the top of the crushing blade 62 and flows along it, so that the bubbles floating in the middle of the liquid collecting barrel 11 can be driven from the center to the outside. Since the speed of the end of the crushing blade 62 is faster, the crushing effect of the crushing blade 62 on the bubbles can be better; After the hot gas in the heat transfer oil is separated, it will enter the condensation tank 51 through the exhaust pipe 55 and be cooled by the heat dissipation fins 52. At this time, the condensed liquid droplets generated by the cooling will flow back to the separation tank 1 through the condensation tank 51 and the return pipe 53 for circulation, thereby avoiding the situation where part of the heat transfer oil is gasified and discharged and wasted. At the same time, the V-shaped bending shape at the bottom of the return pipe 53 can store part of the cooled heat transfer oil in the bending part of the return pipe 53, thereby forming a communicating vessel structure, ensuring that the condensed liquid in the condensation tank 51 can enter the separation tank 1 through the return pipe 53, and at the same time, it can prevent the gas in the separation tank 1 from entering the condensation tank 51 through the return pipe 53, so as to ensure that the gas and liquid pipelines can work separately and avoid mutual interference.
