After the die-casting is completed, in order to improve the processing efficiency, low-temperature heat transfer oil is also used to cool the movable mold and the fixed mold to assist in heat dissipation and shorten the time required for cooling and forming the clutch housing. However, both the preheating process and the cooling process require waiting for a period of time, which is unavoidable and cannot be optimized from the processing flow.

A pipe 412 and a second pipe 413, the first pipe 412 is connected to the first flow channel 411, a second flow channel 421 is opened inside the fixed mold 42, an ejection assembly is installed on the fixed mold 42, an automatic connecting assembly 5 for connecting the first flow channel 411 and the second flow channel 421 is installed between the fixed molds 41 and 42, 43 is installed on one side surface of the fixed mold 41, and a heat transfer oil tank 414 is fixedly connected to the side surfaces of the two fixed molds 41 close to each other, two fixed pipes 4141 facing the first pipe 412 and the second pipe 413 are installed on the heat transfer oil tank 414, and an adjustable connecting mechanism 6 is installed between the two fixed pipes 4141 and the first pipe 412 and the second pipe 413.

[0018] In the existing automobile clutch housing die-casting process, after the movable mold and the fixed mold are closed to form a mold cavity, and before the high-temperature molten metal liquid is injected, high-temperature heat transfer oil is usually used to preheat the movable mold and the fixed mold. After the die-casting is completed, in order to improve the processing efficiency, low-temperature heat transfer oil is also used to cool the movable mold and the fixed mold to assist in heat dissipation and shorten the time required for cooling and forming the clutch housing. However, both the preheating process and the cooling process require waiting for a period of time, which is inevitable and cannot be optimized from the processing flow. Therefore, how to further improve the production and processing efficiency is a problem to be solved; In order to solve the above problems, the present invention sets two sets of die-casting molds 4, and the opening and closing of the two sets of die-casting molds 4 can be controlled by two driving mechanisms 2 respectively. During the die-casting process, the two sets of die-casting molds 4 perform die-casting production of the clutch housing alternately. For example, one set of die-casting molds 4 is preheated after the die-casting is completed and waits for the injection of molten metal liquid, while the other set of die-casting molds 4 is cooled and formed after the die-casting is completed. The advantage of such a setting is that although the time required for the preheating process and the cooling process is inevitable, this part cannot be optimized from the processing flow, but if this time period can be used well, the overall optimization can be further performed from other aspects, thereby improving the processing efficiency; In the present invention, the technical scheme adopted is to optimize the preheating process and the cooling process. Specifically, in the prior art, in order to facilitate the circulation and recycling of heat transfer oil in the movable mold and the fixed mold, a preheating flow channel and a cooling flow channel are usually separately provided for preheating and cooling. The existence of the double flow channels increases the difficulty of production and processing of the fixed mold and the movable mold, and the two flow channels work independently, and the two flow channels will affect each other, thereby reducing the effect of preheating and cooling. In addition, the spacing between the movable mold and the fixed mold is variable. In order to meet the use requirements, a set of high-temperature heat transfer oil supply device and low-temperature heat transfer oil supply device need to be provided on each of the movable mold and the fixed mold, which increases the cost, or the preheating flow channel and the cooling flow channel of the two are connected by means of a connecting pipe, so as to share a set of high-temperature heat transfer oil supply device, but the connecting pipe will move with the change of the spacing between the fixed mold and the movable mold, which may interfere with the staff taking out the formed clutch housing die casting in the subsequent processing process; In order to solve this problem, in the present invention, two heat transfer oil tanks 414 are provided, one of which is responsible for the supply and return of high-temperature heat transfer oil, and the other is responsible for the supply and return of low-temperature heat transfer oil. By providing an adjustable connecting mechanism 6, the two fixed pipes 4141 of the heat transfer oil tank 414 are connected to the first pipeline 412 and the second pipeline 413 respectively by means of the adjustable connecting mechanism 6. By providing an automatic connecting component 5, after the fixed mold 41 and the fixed mold 42 are closed, the first flow channel 411 and the second flow channel 421 can be connected to each other through the automatic connecting component 5, so that the heat transfer oil tank 414 can be connected to the second flow channel 411 and the second flow channel 421. The heat transfer oil passes through one of the fixed pipes 4141 and enters the first pipeline 412 through the connecting function of the adjustable connecting mechanism 6, and then flows along the first flow channel 411 to the automatic connecting component 5 on the fixed mold 41 away from the first pipeline 412. With the mutual connection between the two groups of automatic connecting components 5 on the fixed mold 41 and the fixed mold 42 after mold closing, the heat transfer oil enters the second flow channel 421 and enters the second pipeline 413 along the second flow channel 421. Finally, with the connecting function of the adjustable connecting mechanism 6, it enters the other fixed pipe 4141 and finally flows back to the same heat transfer oil tank 414, completing the circulation flow; Based on the above-mentioned circulation flow process, the adjustable connecting mechanism 6 in the present invention has two connecting states, one is to connect the heat transfer oil tank 414 located on the same fixed mold 41 with the first pipe 412 and the second pipe 413, and the other is to connect the heat transfer oil tank 414 located on different fixed molds 41 with the first pipe 412 and the second pipe 413 on another heat transfer oil tank 414. The two connecting states cooperate with the basic circulation flow process, so that in the present invention, when the heat transfer oil tank 414 with high temperature heat transfer oil is connected to the first pipe 412 and the second pipe 413 through the fixed pipe 4141 and the adjustable connecting mechanism 6, 2. When the circulating flow channel composed of the first flow channel 411, the second flow channel 421, the second pipeline 413 and the two groups of automatic connecting components 5 supplies circulating high-temperature heat-conducting oil to preheat the fixed mold 41 and the fixed mold 42, another heat-conducting oil tank 414 with low-temperature heat-conducting oil supplies circulating low-temperature heat-conducting oil to the circulating flow channel composed of another group of first pipelines 412, the first flow channel 411, the second flow channel 421, the second pipeline 413 and the two groups of automatic connecting components 5 through another group of fixed pipes 4141 and the adjustable connecting mechanism 6 to cool the other group of fixed molds 41 and the fixed mold 42; After preheating and cooling are completed, in the next work process, when the fixed mold 41 and the fixed mold 42 of the subsequent preheating group need to be cooled and the fixed mold 41 and the fixed mold 42 of the cooling group need to be preheated, it is only necessary to switch the connection state of the adjustable connecting mechanism 6. The fixed pipe 4141 on the heat transfer oil tank 414 with high temperature heat transfer oil is connected with the first pipe 412 and the second pipe 413 on the fixed mold 41 that needs to be preheated through the adjustable connecting mechanism 6, and the fixed pipe 4141 on the heat transfer oil tank 414 with low temperature heat transfer oil is connected with the first pipe 412 and the second pipe 413 on the fixed mold 41 that needs to be cooled through the adjustable connecting mechanism 6. Since preheating and cooling can be switched through the adjustable connecting mechanism 6, preheating The hot runner and the cooling runner can share one runner, so the overall operation is simple and easy to use, and the control operation of high and low temperature thermal oil supply is greatly optimized and reduced, thereby saving time and improving the overall processing efficiency. It can effectively solve the above-mentioned problems. In addition, since one of the two die-casting molds 4 is preheating and the other is cooling, and they share the high-temperature thermal oil tank 414 and the low-temperature thermal oil tank 414, the two complement each other in processing flow, so that the frequency of use of both the high-temperature thermal oil tank 414 and the low-temperature thermal oil tank 414 has been doubled, thereby significantly shortening the idle time, and further reducing unnecessary heat loss during the idle process.

[0019] like Figure 2 and Figure 6As shown, the protection mechanism 3 includes a top plate 31, which is fixedly connected to the output end of the telescopic cylinder 21. Two first mounting holes 32 are symmetrically opened on the top plate 31. First limit rods 33 are slidably connected in the two first mounting holes 32. One end of the first limit rod 33 is fixedly connected to the fixed mold 42. A protection spring 34 is sleeved on the first limit rod 33, and the protection spring 34 is located between the top plate 31 and the fixed mold 42.

[0020] By controlling the extension or contraction of the telescopic cylinder 21, the top plate 31 can be driven to approach the fixed die 41 or move away from the fixed die 41 with the help of the output end of the telescopic cylinder 21. In this process, the fixed die 42 is driven to approach the fixed die 41 or move away from the fixed die 41 with the help of the elastic force of the protection spring 34 on the top plate 31 and the fixed die 42. With the help of the elastic buffering effect of the protection spring 34, in the process of driving the fixed die 42 to approach the fixed die 41 and completing the mold closing with the fixed die 41, the situation of damage to the die-casting mold 4 caused by too fast mold closing due to operational errors can be prevented.

[0021] like Figure 6 and Figure 7 As shown, the ejection assembly includes two ejection grooves 422 opened on the fixed mold 42, and the two ejection grooves 422 are slidably connected with ejection rods 423, and the ejection rods 423 are fixedly connected with a pressure plate 424, and a third bracket 22 is fixedly connected between the telescopic cylinder 21 and the bottom plate 11, and a mounting frame 23 is installed on the telescopic cylinder 21, and a baffle 24 facing the pressure plate 424 is installed on the mounting frame 23, and an automatic reset assembly is installed on the pressure plate 424.

[0022] After the clutch housing die-casting is cooled and formed, the telescopic cylinder 21 is controlled to shorten, driving the fixed mold 42 away from the fixed mold 41 for mold opening. During the mold opening process, as the telescopic cylinder 21 shortens, the fixed mold 42 drives the ejector rod 423 and the pressure plate 424 to approach the baffle 24. After the pressure plate 424 is supported by the baffle 24, as the telescopic cylinder 21 further shortens, the end of the ejector rod 423 away from the baffle 24 extends from the ejector groove 422, thereby ejecting the formed clutch housing die-casting from the fixed mold 42.

[0023] like Figure 6 , Figure 7 and Fig. 9 As shown, the automatic reset assembly includes a second mounting hole 4241 opened on the pressure plate 424, and a second limiting rod 425 is slidably connected in the second mounting hole 4241. One end of the second limiting rod 425 is fixedly connected to the fixed mold 42. The cross-sections of the first limiting rod 33 and the second limiting rod 425 are both T-shaped. A reset spring 426 is sleeved on the second limiting rod 425, and the reset spring 426 is located between the pressure plate 424 and the fixed mold 42.

[0024] By providing an automatic reset component, after the clutch housing die-casting is demoulded and ejected, during the mold closing process, the elastic force of the reset spring 426 can be used to drive the pressure plate 424 to move to the side away from the fixed mold 42, thereby driving the ejection rod 423 to retract into the ejection groove 422 to complete automatic reset.

[0025] like Figure 3 , Figure 4 , Figure 5 , Figure 7 and Figure 8 As shown, the automatic connection component 5 includes four empty slots 51 in groups of two, and the two groups of empty slots 51 are respectively opened on the side surface of the fixed mold 41 close to the fixed mold 42 and the side surface of the fixed mold 42 close to the fixed mold 41. The empty slots 51 are fixedly connected with first guide members 52. The two first guide members 52 on the fixed mold 41 are respectively connected with the first flow channel 411 and the second pipeline 413. The two first guide members 52 on the fixed mold 42 are both connected with the second flow channel 421. The second guide member 53 is rotatably connected between the inner surface of the empty slot 51 and the outer surface of the first guide member 52. The first guide hole 52 is opened on one side surface of the first guide member 52. 1. A second flow guide member 531 corresponding to the first flow guide hole 521 is provided on a side surface of the second flow guide member 53 close to the first flow guide member 52, a spiral guide groove 532 is provided on the outer surface of the second flow guide member 53, a slide groove 54 is provided on the inner surface of the empty groove 51, a fixed column 55 is fixedly connected to a side surface of the fixed mold 41 and the fixed mold 42 close to the second flow guide member 53, a 551 matching the spiral guide groove 532 is fixedly connected to the fixed column 55, a sealing groove is provided on a side surface of the second flow guide member 53 on the fixed mold 41, and a sealing convex ring corresponding to the sealing groove is installed on a side surface of the second flow guide member 53 on the fixed mold 42.

[0026] In the non-mold-closing state, the first guide hole 521 and the second guide member 531 are just staggered by 180 degrees, and the automatic connecting components 5 on the fixed mold 41 and the fixed mold 42 are in a closed state, so as to keep the first flow channel 411 and the second flow channel 421 sealed. In the mold-closing process, as the fixed mold 41 and the fixed mold 42 approach each other, the fixed column 55 on the fixed mold 41 extends into the slide groove 54 on the fixed mold 42, and correspondingly, the fixed column 55 on the fixed mold 42 extends into the slide groove 54 on the fixed mold 41. Then, as the fixed mold 41 and the fixed mold 42 continue to approach each other, 551 enters the spiral guide groove 532, and by squeezing the side wall of the spiral guide groove 532, the second guide member 53 is driven to rotate in the empty groove 51. Since the number of spiral turns of the spiral guide groove 532 is half a turn, the fixed mold 41 When the mold is closed with the fixed mold 42, the second flow guide member 53 will rotate 180° under the pressure of 551 on the spiral guide groove 532, so that the second flow guide member 531 is aligned with the first flow guide hole 521, and at this time, the second flow guide members 531 between the corresponding automatic connecting components 5 on the fixed mold 41 and the fixed mold 42 are also aligned with each other, and the two opposite automatic connecting components 5 in each group are connected through the aligned second flow guide members 531 and the first flow guide hole 521. When the mold is opened subsequently, as the fixed mold 41 and the fixed mold 42 move away from each other, under the pressure of 551 on the side wall of the spiral guide groove 532, the second flow guide member 53 will rotate 180°, restore the offset between the second flow guide member 531 and the first flow guide hole 521, and realize the automatic closing of the automatic connecting component 5.

[0027] like Figure 1 , Fig.10 , Fig.11 , Fig.12 and Fig.13 As shown, the adjustable connecting mechanism 6 includes two mounting plates 61, a fixed shaft 62 is fixedly connected between the two mounting plates 61, a card slot 63 is provided on the surface of one side of the two mounting plates 61 close to each other, two groups of first through holes 64 arranged in groups of two are provided on the two mounting plates 61, a connecting device 65 is rotatably connected to the fixed shaft 62, a clamping ring 651 is fixedly connected to both ends of the connecting device 65, the clamping ring 651 is sealingly rotatably connected in the card slot 63, two groups of straight holes 652 in groups of two are symmetrically provided in the connecting device 65, two groups of spiral curved holes 653 in groups of two are spirally symmetrically provided in the connecting device 65, the number of spiral turns of the spiral curved holes 653 is 0.5, the first through hole 64 close to the thermal oil tank 414 is fixedly connected and connected to the fixed pipe 4141, the first through hole 64 away from the thermal oil tank 414 is fixedly connected and connected to the first pipe 412 and the second pipe 413, and a self-adjusting component is installed on the mounting plate 61.

[0028] On the connecting device 65, the inlet end and the outlet end of the straight hole 652 are directly opposite to each other, and the inlet end and the outlet end of the spiral hole 653 are 180 degrees around the axis of the connecting device 65. Therefore, when the two straight holes 652 in the same group are connected with the first through hole 64, the adjustable connecting mechanism 6 connects the heat transfer oil tank 414, the fixed pipe 4141 located on the same fixed mold 41 and the first pipeline 412 and the second pipeline 413 located on the same fixed mold 41 through the two groups of first through holes 64 and one group of straight holes 652 on the same side. When the two spiral bend holes 653 of the same group are connected with the first through hole 64, the inlet to the outlet rotates 180°, so the adjustable connecting mechanism 6 connects the thermal oil tank 414 and the fixed pipe 4141 located on different fixed molds 41 with the first pipeline 412 and the second pipeline 413 located on different fixed molds 41 through the two groups of first through holes 64 and one group of spiral bend holes 653 on different sides. Therefore, the adjustable connecting mechanism 6 has two different connecting states, and the switching can be realized by rotating the connecting device 65 by 90°. like Figure 2 , Fig.10 and Fig.14 As shown, the self-adjusting component includes two symmetrical connecting frames 66, both ends of the connecting frames 66 are fixedly connected to the two mounting plates 61, a gear 654 is fixedly connected to the outer surface of the connecting device 65, a limiting member 67 is fixedly connected to the inner surface of the connecting frame 66, a rack 68 is slidably connected inside the limiting member 67, the rack 68 is meshingly connected to the gear 654, and a push rod 35 facing the rack 68 is fixedly connected to the top plate 31.

[0029] In order to further simplify the operating process and improve processing efficiency, a self-adjusting component is set up. With the help of the movement of the fixed mold 42 in the mold closing close to the fixed mold 41, the push rod 35 is driven to approach and contact the rack 68, and then the rack 68 is pushed, and the connecting device 65 is driven to rotate 90° with the help of the meshing action, thereby realizing automatic adjustment of the connecting state of the adjustable connecting mechanism 6.

[0030] In the present invention, the two die-casting molds 4 are staggered by half a working cycle in the process, one of which is preheating while the other is cooling. During the die-casting process, when one of the die-casting molds 4 needs to be molded and preheated, the corresponding telescopic cylinder 21 is first controlled to extend, and the output end of the telescopic cylinder 21 drives the fixed mold 42 to move toward the fixed mold 41 through the protection mechanism 3 until the two are fitted to form a mold cavity. During the mold closing process, as the fixed mold 41 and the fixed mold 42 approach, the fixed column 55 on the fixed mold 41 extends into the slide groove 54 on the fixed mold 42, and correspondingly, the fixed column 55 on the fixed mold 42 extends into the slide groove 54 on the fixed mold 41, and then as the fixed mold 41 and the fixed mold 42 continue to approach, 551 enters the spiral guide groove 532 and squeezes the side of the spiral guide groove 532. The wall drives the second flow guide 53 to rotate in the empty groove 51. Since the number of spiral turns of the spiral guide groove 532 is half a turn, when the fixed mold 41 and the fixed mold 42 complete the mold closing, the second flow guide 53 will be squeezed by 551 on the spiral guide groove 532, and just rotate 180°, so that the second flow guide 531 is aligned with the first flow guide hole 521, and at this time, the second flow guides 531 between the corresponding automatic connecting components 5 on the fixed mold 41 and the fixed mold 42 are also aligned with each other, and the two opposite automatic connecting components 5 of each group are connected through the aligned second flow guides 531 and the first flow guide hole 521. At this time, the first pipeline 412, the first flow channel 411, the second flow channel 421, the second pipeline 413 and the two groups of automatic connecting components 5 in the die-casting mold 4 form a smooth circulation flow channel; At the same time, the movement of the fixed mold 42 in the mold closing process close to the fixed mold 41 will drive the push rod 35 to approach and contact the rack 68, and then by pushing the rack 68, the connecting device 65 is driven to rotate 90° by meshing, so that the adjustable connecting mechanism 6 connects the first pipe 412 and the second pipe 413 on the die-casting mold 4 with the two fixed pipes 4141 on the thermal oil tank 414 with high-temperature heat-conducting oil, and the inner mold cavity of the die-casting mold 4 is preheated by the circulating high-temperature heat-conducting oil. In this process, for another die-casting mold 4, the adjustable connecting mechanism 6 connects the first pipe 412 and the second pipe 413 on the die-casting mold 4 with the two fixed pipes 4141 on the thermal oil tank 414 with low-temperature heat-conducting oil, and automatically switches it to a cooling state; After one of the die-casting molds 4 is preheated and die-casting is completed, when cooling is required, since the two die-casting molds 4 are staggered by half a working cycle in the process, the other die-casting mold 4 is in a state of needing mold closing and preheating at this time. Therefore, with the help of the other die-casting mold 4, the push rod 35 can be driven to approach and contact the rack 68 according to the above-mentioned mold closing process, and then the rack 68 is pushed to drive the connecting device 65 to rotate 90° with the help of the meshing action, thereby realizing automatic adjustment of the connecting state of the adjustable connecting mechanism 6, and automatically switching the heat transfer oil in the circulating flow channel of the die-casting mold 4 after preheating and die-casting is completed to the low-temperature heat transfer oil required for cooling.
