Description

Technical Field

[0001] The invention relates to the technical field of die-casting machines, in particular to a die-casting machine mold clamping hydraulic device. Background Art

[0002] Die-cast products are formed by rapid cooling of molten metal under high pressure in the mold. The injection speed and pressurization process in the die-casting process have a great influence on the quality of the casting products. The molten metal cools and solidifies under the action of the final static pressure. The magnitude of the static pressure depends on the complexity of the die-casting, the alloy properties and the quality requirements of the die-casting. It is generally 50-500MPa. The total force acting on the die-casting is borne by the clamping mechanism to bear the required clamping force, and is achieved by the elastic deformation of the four tie rods of the clamping mechanism.

[0003] For example, the pressurized clamping hydraulic mechanism of the heavy-duty die-casting machine of the Chinese patent, publication number CN104999048A, starts with the oil pressure in the clamping cylinder, and changes the pressure in the clamping cylinder by means of pressurization while ensuring that the system pressure remains unchanged. It can improve work efficiency, reduce energy consumption, and reduce machine costs without increasing the oil pump displacement or increasing the system pressure. It has the characteristics of simple and reasonable structure, reliable performance, low manufacturing cost, easy production, easy implementation, high work efficiency, low energy consumption, and strong practicality.

[0004] However, if the driving speed of the clamping mechanism is too fast, it is easy to cause a hard fit between the first mold 1 and the second mold 2, thereby damaging the first mold and the second mold. At the same time, too fast a fit will cause the first mold and the second mold to collide during fit, resulting in rebound, making it impossible for the locking device to engage in the first time. Such rebound can easily cause the locking device to get stuck, resulting in a failure of clamping or even damage to the mold. Summary of the invention

This design ensures stable mold locking between the first mold and the second mold, while improving the reliability of mold locking through the precise matching of the locking rod and the locking block. In addition, by setting the guide device - the plug rod and the slot between the molds, the guiding function in the mold locking process is enhanced, ensuring that the locking component is more stable during operation, reducing the possibility of misalignment and matching errors, and maximizing the stability and reliability of the mold in the mold clamping and locking process, significantly reducing the error in mold operation, and improving production efficiency and product quality.

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.

[0041] Example 1

[0044] The second mold 2 is also provided with a hydraulic connecting rod 4 , and the second mold 2 is also connected to the first mold 1 via the hydraulic connecting rod 4 .

[0045] A matching component 5 is provided in the insertion rod 31, and the insertion rod 31 matches with the slot 32 through the matching component 5;

[0046] The mating component 5 includes a mating groove 51 formed on the inserting rod 31 , and a mating block 52 adapted to the mating groove 51 is provided on the inserting slot 32 , and the mating block 52 is inserted into the mating groove 51 .

[0047] A locking assembly 6 is also provided in the matching groove 51, and the locking assembly 6 is used to lock the first mold 1 and the second mold 2;

[0048] The locking assembly 6 includes a locking rod 61 arranged in the matching groove 51, a locking block 62 is slidably arranged on the locking rod 61, a locking groove 63 is opened on the matching block 52, the locking block 62 is adapted to the locking groove 63, and the locking block 62 is inserted into the locking groove 63.

[0049] In this embodiment:

[0050] Locking connection: A locking assembly 6 is provided in the mating groove 51, and the mating groove 51 and the mating block 52 can be locked through the cooperation of the locking rod 61 and the locking block 62, thereby completing the locking between the insertion rod 31 and the slot 32, and since the insertion rod 31 and the slot 32 are respectively connected to the first mold 1 and the second mold 2, the first mold 1 and the second mold 2 are locked through the cooperation of the locking rod 61 and the locking block 62.

[0051] Guiding cooperation: By respectively arranging an insert rod 31 and a slot 32 between the first mold 1 and the second mold 2, in addition to the hydraulic connecting rod 4 of the driving device normally used for mold closing, there is also an additional guiding device between the first mold 1 and the second mold 2. Through the cooperation of the insert rod 31 and the slot 32, the locking component 6 of mold closing and locking has a guiding function, so that the locking rod 61 and the locking block 62 can be more stable when cooperating.

[0052] Matching locking: By setting a matching groove 51 and a matching block 52 in the connecting component 3, the guiding function of the insertion rod 31 and the slot 32 is strengthened and the stability of the insertion rod 31 and the slot 32 when they match with each other is increased, preventing the insertion rod 31 and the slot 32 from being misaligned when sliding, which in turn causes a matching error between the locking rod 61 and the locking block 62, making it impossible for the first mold 1 and the second mold 2 to be locked normally.

[0053] Summary: By setting the locking assembly 6 in the matching groove 51, reliable locking between the matching groove 51 and the matching block 52 is achieved, making the connection between the insertion rod 31 and the slot 32 more stable.

[0054] Example 2

[0055] See also Figure 1-7, a driving assembly 7 is also provided in the locking rod 61, and the driving assembly 7 is used to resist the locking block 62 and be inserted into the locking groove 63;

[0056] The driving assembly 7 includes a hollow tube 71 disposed in the locking rod 61 . An elastic rubber sleeve 72 is disposed on the hollow tube 71 . The hollow tube 71 and the elastic rubber sleeve 72 are communicated with each other.

[0057] In this embodiment:

[0058] Contact drive: In order to allow the locking block 62 to be inserted into the locking groove 63, a driving component 7 is also provided in the locking rod 61, including a hollow tube 71 and an elastic rubber sleeve 72. When the insertion rod 31 slides toward the direction close to the slot 32, the matching groove 51 and the matching block 52 will cooperate with each other to squeeze the gas into the hollow tube 71. The gas entering the hollow tube 71 will be guided into the elastic rubber sleeve 72, causing the elastic rubber sleeve 72 to undergo elastic deformation and contact the locking block 62, thereby driving the locking block 62 to slide in the locking rod 61 and be inserted into the locking groove 63 to complete the mold locking.

[0059] Summary: By arranging the driving assembly 7 in the locking rod 61, the locking block 62 can be more efficiently inserted into the locking groove 63. This design improves the accuracy and efficiency of the locking block operation in the prior art and reduces manual intervention and potential errors. Through this automated mold clamping process, not only the stability and reliability of the mold clamping are improved, but also the production efficiency and product quality are significantly improved, making the mold operation safer and more convenient.

[0060] Example 3

[0061] See also Figure 1-7 , a stabilizing assembly 8 is also provided on the locking rod 61, and a locking block 62 is slidably provided on the locking rod 61 through the stabilizing assembly 8;

[0062] The stabilizing assembly 8 includes a sliding groove 81 formed on the locking rod 61, and a sliding block 82 adapted to the sliding groove 81 is provided on the locking block 62, and the sliding block 82 is slidably disposed in the sliding groove 81;

[0063] The locking block 62 is also provided with a resisting rod 85 , and the locking block 62 is also resisted against the elastic rubber sleeve 72 through the resisting rod 85 .

[0064] The stabilizing assembly 8 also includes a limiting rod 83 arranged inside the locking rod 61, a sliding block 82 is slidably arranged on the limiting rod 83, and a return spring 84 is also arranged on the sliding block 82. The sliding block 82 is also connected to the locking rod 61 through the return spring 84, and the return spring 84 is sleeved on the outer side of the limiting rod 83.

[0065] In this embodiment:

[0066] Sliding: In order to meet the sliding requirements of the locking block 62, a stabilizing component 8 is also provided in the locking rod 61. Through the cooperation between the sliding groove 81 and the sliding block 82, the locking block 62 can slide on the locking rod 61, and then the locking block 62 can slide into the locking groove 63 under the action of the driving component 7 to complete the mold locking.

[0067] Improve stability: In order to make the sliding block 82 slide more stably in the sliding groove 81, a limiting rod 83 is also provided in the sliding groove 81. The two ends of the limiting rod 83 are respectively connected to the locking rod 61. The sliding block 82 is slidably set on the limiting rod 83. The sliding of the sliding block 82 is limited by the limiting rod 83, so that its sliding is more stable, and the locking block 62 can be more stably inserted into the locking groove 63.

[0068] Anti-falling: In order to prevent the locking block 62 from sliding out of the locking rod 61 under the influence of gravity, thereby causing the device to fail, a reset spring 84 is also provided on the locking block 62, and the locking block 62 is also elastically connected via the reset spring 84. By providing the reset spring 84, the locking block 62 is elastically fixed so that it will not fall out of the locking rod 61 due to the action of gravity, thereby causing the device to fail to lock.

[0069] Summary: By setting a stabilizing component 8 in the locking rod 61, the locking block 62 can slide more smoothly into the locking groove 63. The stabilizing component 8 includes a sliding groove 81 and a sliding block 82. When the sliding block 82 slides in the sliding groove 81, it is limited by the limiting rod 83 to ensure the stability of the sliding process, so that the locking block 62 can be more accurately inserted into the locking groove 63 to complete the mold locking. In addition, in order to prevent the locking block 62 from falling off due to gravity, a reset spring 84 is designed to elastically connect the locking block 62 to the locking rod 61 to ensure that the locking block 62 will not slide out, thereby ensuring the normal locking operation of the device. These improvements greatly improve the stability and reliability of the mold locking process and reduce the risk of device failure due to gravity and sliding instability. Overall, this design not only improves the accuracy and safety of mold operation, but also improves production efficiency and product quality, making the entire mold locking process more efficient and reliable.

[0070] Example 4

[0071] See also Figure 1-7 , a booster assembly 9 is also provided in the matching groove 51, and the booster assembly 9 is used to slow down the sliding speed of the matching block 52 in the matching groove 51;

[0072] The boost assembly 9 includes an outer ring block 91 installed in the matching groove 51 . The matching block 52 is provided with a through hole 92 . The outer ring block 91 is also provided with a closing plug 93 adapted to the through hole 92 . The closing plug 93 is inserted into the through hole 92 .

[0073] A plurality of closing plugs 93 are provided on the outer ring block 91 , and the lengths of the closing plugs 93 are different. The outer diameter of each closing plug 93 gradually decreases from the side close to the outer ring block 91 to the side away from the outer ring block 91 .

[0074] In this embodiment:

[0075] Boosting and decelerating: In order to prevent the first mold 1 and the second mold 2 from approaching each other too quickly under the drive of the hydraulic connecting rod 4, thereby causing a hard fit between the first mold 1 and the second mold 2, and further damaging the first mold 1 and the second mold 2, and at the same time, the first mold 1 and the second mold 2 approaching each other at too fast a speed will also cause errors in the fit between the locking block 62 and the locking groove 63. Therefore, a boosting component 9 is provided in the fitting groove 51. When the fitting block 52 slides in the fitting groove 51, the closing plug 93 provided on the outer ring block 91 will gradually be inserted into the through hole 92 and close the through hole 92, so that the pressure of the fitting block 52 when sliding in the fitting groove 51 increases, thereby slowing down the sliding speed between the insertion rod 31 and the slot 32, thereby playing the role of boosting and decelerating, and forming protection for the first mold 1 and the second mold 2 and between the locking block 62 and the locking groove 63.

[0076] Multiple adjustments: In order to prevent the air pressure from reaching the maximum resistance value too quickly, thereby causing damage to the hydraulic connecting rod 4, the lengths of the multiple closing plugs 93 are different, so that the time nodes for the rose closing plug 93 to block the through hole 92 are different, so that the hydraulic connecting rod 4 will not encounter the maximum resistance too quickly when pulling the first mold 1 close to the second mold 2, thereby protecting the hydraulic connecting rod 4. At the same time, the diameter of the closing plug 93 decreases from one side to the other side, so that the closing plug 93 can be inserted into the through hole 92 more conveniently.

[0077] Sealing: By providing the booster assembly 9 , the locking rod 61 forms a seal, thereby preventing the gas input into the locking rod 61 from flowing back, thereby improving the stability of the locking block 62 .

[0078] Summary: By setting the booster assembly 9 in the matching groove 51, the hard matching problem caused by the first mold 1 and the second mold 2 approaching too fast under the drive of the hydraulic connecting rod 4 is effectively prevented, and the mold damage is avoided. In addition, by gradually inserting the closing plug 93 into the through hole 92, the booster assembly 9 increases the pressure when the matching block 52 slides, slowing down the sliding speed between the plug 31 and the slot 32, achieving the effect of boosting and decelerating, thereby protecting the mold and the locking assembly. A plurality of closing plugs 93 of different lengths are designed so that the air pressure will not reach the maximum resistance value too quickly, protecting the hydraulic connecting rod 4 from damage. At the same time, the diameter of the closing plug 93 is designed to decrease gradually, ensuring that it can be easily inserted into the through hole 92. This design improves the accuracy and safety of the hydraulic connection in the prior art, and prevents gas backflow through the sealing function of the booster assembly 9, thereby improving the stability of the locking block 62. These improvements significantly improve the reliability and stability of the mold locking and operation process, reduce the risk of equipment failure caused by excessive speed and gas backflow, improve production efficiency and product quality, and make the entire clamping process safer, more efficient and reliable.

[0079] Example 5

[0080] See also Figure 1-7 , a gas delivery assembly 10 is also provided in the locking rod 61, and the gas delivery assembly 10 is used to input gas into the hollow tube 71;

[0081] The gas delivery assembly 10 includes a gas delivery groove 101 formed on the locking rod 61 . A transfer groove 102 is further formed in the locking rod 61 . The gas delivery groove 101 is connected to the hollow tube 71 via the transfer groove 102 .

[0082] In this embodiment:

[0083] Gas input: In order to allow the matching groove 51 and the matching block 52 to squeeze air into the locking rod 61 during the matching process, thereby allowing the elastic rubber sleeve 72 to expand to resist the sliding of the locking block 62, a gas delivery component 10 is also arranged in the locking rod 61, wherein the gas delivery groove 101 connects the locking rod 61 with the outside, the adapter groove 102 connects the locking rod 61 and the elastic rubber sleeve 72, and the gas delivery groove 101 and the sliding adapter groove 102 are connected to each other, so that the hollow tube 71 is connected to the outside through the gas delivery groove 101 and the adapter groove 102, so that external air can enter the hollow tube 71.

[0084] Example 6

[0085] See also Figure 1-7 , a reinforcing component 11 is also provided on the matching block 52, and the reinforcing component 11 is used to strengthen the connection between the matching block 52 and the matching groove 51;

[0086] The reinforcing component 11 includes a reinforcing slot 111 opened on the matching block 52, and a reinforcing magnetic plug-in block 112 adapted to the reinforcing slot 111 is provided on the locking block 62. The reinforcing magnetic plug-in block 112 is inserted into the reinforcing slot 111, and the reinforcing magnetic plug-in block 112 and the matching block 52 are magnetically connected.

[0087] In this embodiment:

[0088] Strengthening the connection stability: In order to make the locking formed between the locking block 62 and the locking groove 63 more stable, a gas delivery assembly 10 is also provided on the mating block 52. The reinforced slot 111 provided on the mating block 52 and the reinforced magnetic plug 112 provided on the locking block 62 cooperate with each other, thereby forming an additional connection, thereby making the locking between the mating groove 51 and the mating block 52 more secure.

[0089] Magnetic connection: Since the magnetic connection between the reinforcing magnetic plug block 112 and the matching block 52 is established, the locking block 62 is more firmly fixed in the locking groove 63 to prevent the locking block 62 from falling out of the locking groove 63 during the processing.

[0090] Summary: By setting the reinforcing component 11, the stability between the locking block 62 and the locking groove 63 is enhanced, and the reliability and safety of the entire mold locking process are improved. The magnetic connection design reduces the possibility of the locking block falling off due to mechanical vibration and external force, improves the overall operating efficiency and product quality of the equipment, and ensures the stability and safety of the mold during the production process. These improvements not only optimize the locking mechanism in the prior art, but also provide higher operating accuracy and stability, making the mold operation more efficient and reliable.
