Description

Technical Field

[0001] The utility model relates to the technical field of die casting, in particular to an automatic die clamping mechanism for die casting equipment. Background Art

[0002] Die casting is a metal casting process, which is characterized in that high pressure is applied to molten metal by using the inner cavity of a mold. The mold is usually processed from an alloy with higher strength, and this process is somewhat similar to injection molding. The cost of casting equipment and molds is high, so the die casting process is generally only used for mass production of a large number of products.

[0003] The die casting bracket mold is usually used in cooperation with an injection structure, specifically, the die casting bracket mold is clamped and fixed, and then the injection structure injects molten metal into the mold. This method requires the die casting bracket mold to be clamped accurately and stably. However, in actual production, many die casting bracket molds will have their molds not fully in place due to pushing deviation, resulting in a low yield of final finished products. Contents of the Utility Model

[0004] In view of the above deficiencies, the purpose of the utility model is to provide an automatic die clamping mechanism for die casting equipment, which accurately pushes the die through a multi-axis drive slider, and the dies are mutually matched and embedded, so that the die combination is accurate and cannot be deviated subsequently, with high automation degree and high precision, effectively improving the production efficiency and ensuring the yield of finished products.

[0005] The technical solution adopted by the utility model to achieve the above purpose is as follows:

[0006] An automatic die clamping mechanism for die casting equipment, comprising a main support erected on a plane, a die set arranged on the main support, a limit frame arranged in the middle of the die set, and at least one set of axial sliding assemblies arranged between the die sets and protruding toward the middle of the limit frame. The axial sliding assembly comprises a fixed table arranged on the die set, a servo motor arranged on the fixed table with an output shaft protruding toward the middle of the limit frame, a slider arranged on the output shaft of the servo motor, and a die arranged outside the slider. At least one fitting groove for the matching insertion of other sets of dies is formed on the side edge of the die.

[0010] As a further improvement of this utility model, the second axial sliding assembly includes a second fixed platform disposed at the lower part of the mold frame, a second servo motor disposed on the second fixed platform and whose output shaft protrudes toward the middle of the limiting frame, a second slider disposed on the output shaft of the second servo motor, and a second mold disposed on the outside of the second slider, wherein a second fitting groove is symmetrically formed on the side of the second mold.

[0011] As a further improvement of this utility model, the third axial sliding assembly includes a third fixed platform disposed at the left end of the mold frame, a third servo motor disposed on the third fixed platform with its output shaft protruding towards the center of the limiting frame, a third slider disposed on the output shaft of the third servo motor, and a third mold disposed outside the third slider. The third mold has symmetrically formed third fitting grooves on its side. The third mold is inserted into the left end embedding groove of the first mold and the second mold under the drive of the third servo motor. The side of the first mold is inserted into the upper embedding groove of the third mold, and the side of the second mold is inserted into the lower embedding groove of the third mold.

[0012] As a further improvement of this utility model, the fourth axial sliding assembly includes a fourth fixed platform disposed at the right end of the mold frame, a fourth servo motor disposed on the fourth fixed platform with its output shaft protruding towards the center of the limiting frame, a fourth slider disposed on the output shaft of the fourth servo motor, and a fourth mold disposed outside the fourth slider. The fourth mold has symmetrically formed fourth fitting grooves on its side. The fourth mold is inserted into the right end embedding groove of the first mold and the second mold under the drive of the fourth servo motor. The side of the first mold is inserted into the upper embedding groove of the fourth mold, and the side of the second mold is inserted into the lower embedding groove of the fourth mold.

[0013] As a further improvement of this utility model, the limiting frame includes four sets of limiting blocks that are generally triangular in shape, and at least one front limiting plate that is disposed on the limiting blocks and whose shape matches the four sets of limiting blocks. The four sets of limiting blocks are evenly arranged in the middle of the mold frame, and a limiting channel is formed between each pair of them for the slider and the mold to slide. A limiting inspection port is opened in the middle of the front limiting plate.

[0014] As a further improvement of this utility model, the mold frame includes a back plate disposed on the main support and a front plate disposed on the back plate. The axial sliding assembly is disposed between the back plate and the front plate. The limiting frame is located between the back plate and the front plate and is disposed in the middle of the back plate. A material injection hole is formed in the middle of the back plate, and a front inspection port is formed in the middle of the front plate.

[0015] The beneficial effects of this utility model are as follows:

[0016] The automatic mold-setting mechanism of this die-casting equipment is configured to include a main support mounted on a plane, a mold frame mounted on the main support, a limiting frame located in the middle of the mold frame, and at least one set of axial sliding components located between the mold frames and protruding towards the middle of the limiting frame. Each axial sliding component includes a fixed platform mounted on the mold frame, a servo motor mounted on the fixed platform with its output shaft protruding towards the middle of the limiting frame, a slider mounted on the output shaft of the servo motor, and a mold located outside the slider. The mold has at least one fitting groove formed on its side for other sets of molds to be fitted into. During production, different sets of axial sliding components operate sequentially. For example, one set of axial sliding components works with a fixed mold. The servo motor drives the slider and the mold to press towards the fixed mold, causing the edge of the fixed mold to embed into the fitting groove on the mold of the axial sliding component, thereby completing the combination of the two molds. For example, in an axial sliding assembly consisting of two sets, the servo motor of the first set drives the slider and mold of the first set to move toward the center of the limiting frame, and the servo motor of the second set drives the slider and mold of the second set to move toward the center of the limiting frame, so that the side of the mold of the second set is embedded in the fitting groove on one side of the mold of the first set. The two cooperate with each other to complete the mold assembly. Alternatively, there is a fixed mold, the other side of the mold of the first set is embedded in the edge of the fixed mold, and the other side of the mold of the second set is embedded in the other edge of the fixed mold to complete the mold assembly. The system comprises three sets of axial sliding components. The servo motor of the first set drives the slider and mold of the first set to move towards the center of the limiting frame. The servo motor of the second set drives the slider and mold of the second set to move towards the center of the limiting frame, and the side of the mold of the second set is embedded in the fitting groove on one side of the mold of the first set. The servo motor of the third set drives the slider and mold of the third set to move towards the center of the limiting frame, and the side of the mold of the third set is embedded in the fitting groove on the other side of the mold of the first set. This ensures that the three sets of molds fit tightly and restrict each other, thereby making the mold assembly precise and preventing subsequent deviation. The system has a high degree of automation and high precision, effectively improving production efficiency and ensuring the yield of finished products.If there are four sets of axial sliding components, the servo motor of the first set drives the slider and mold of the first set to move towards the center of the limiting frame. The servo motor of the second set drives the slider and mold of the second set to move towards the center of the limiting frame. The servo motor of the third set drives the slider and mold of the third set to move towards the center of the limiting frame, and the upper side of the mold of the third set is embedded in the embedding groove on the left side of the mold of the first set, and the lower side is embedded in the embedding groove on the left side of the mold of the second set. The servo motor of the fourth set drives the slider and mold of the fourth set to move towards the center of the limiting frame, and the upper side of the mold of the fourth set is embedded in the embedding groove on the right side of the mold of the first set, and the lower side is embedded in the embedding groove on the right side of the mold of the second set. This makes the four sets of molds fit tightly and restrict each other, so that the mold assembly is accurate and cannot be offset later.

[0017] After the axial sliding component moves into place, the molds on it are assembled into a whole mold cavity. The external injection mechanism extends into the mold cavity from the back of the mold frame, thereby die-casting and completing the entire production process. The whole process is highly automated, and the mold assembly is precise and cannot be offset later, which effectively improves the production efficiency and ensures the yield of finished products.

[0018] By setting a limiting frame in the middle of the mold frame, the slider and mold pushed by the servo motor are radially restricted. The slider and mold move within the limiting frame, effectively preventing them from shifting and improving the accuracy of the servo motor in conveying the mold. By setting a fixed platform on the mold frame, the position of the servo motor is fixed, effectively preventing the servo motor from shifting during use and causing inaccurate mold conveying, further improving the accuracy of the automatic mold-setting mechanism of this die-casting equipment.

[0028] To further illustrate the technical means and effects adopted by this utility model to achieve its intended purpose, the specific implementation methods of this utility model will be described in detail below with reference to the accompanying drawings and preferred embodiments.

[0029] In the description of this utility model, it should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0030] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0031] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0032] Please refer to Figures 1 to 7 This utility model provides an automatic mold-setting mechanism for die-casting equipment, including a main support 1 mounted on a plane, a mold frame 2 mounted on the main support 1, a limiting frame 3 located in the middle of the mold frame 2, and at least three sets of axial sliding components located between the mold frames 2 and protruding towards the middle of the limiting frame 3. The axial sliding components include a fixed platform mounted on the mold frame 2, a servo motor mounted on the fixed platform with its output shaft protruding towards the middle of the limiting frame 3, a slider mounted on the output shaft of the servo motor, and a mold located outside the slider. At least one fitting groove is formed on the side of the mold for other sets of molds to be matched and inserted.

[0033] During production, different sets of axial sliding components operate sequentially. For example, one set of axial sliding components works with a fixed mold. A servo motor drives the slider and mold to press towards the fixed mold, causing the edge of the fixed mold to engage in the fitting groove of the axial sliding component's mold, thus completing the combination of the two molds. Alternatively, two sets of axial sliding components can be used. The servo motor of the first set drives the slider and mold of the first set to move towards the center of the limiting frame 3. The servo motor of the second set drives the slider and mold of the second set to move towards the center of the limiting frame 3, causing the side of the mold of the second set to engage in the fitting groove on one side of the mold of the first set. The two work together to complete the mold combination. Another option is to have a fixed mold. The other side of the mold of the first set engages in the edge of the fixed mold, and the other side of the mold of the second set engages in the other edge of the fixed mold, completing the mold combination. The system comprises three sets of axial sliding components. The servo motor of the first set drives the slider and mold of the first set to move towards the center of the limiting frame 3. The servo motor of the second set drives the slider and mold of the second set to move towards the center of the limiting frame 3, and the side of the mold of the second set is embedded in the fitting groove on one side of the mold of the first set. The servo motor of the third set drives the slider and mold of the third set to move towards the center of the limiting frame 3, and the side of the mold of the third set is embedded in the fitting groove on the other side of the mold of the first set. This ensures that the three sets of molds fit tightly and restrict each other, thereby making the mold assembly precise and preventing subsequent deviation. The system has a high degree of automation and high precision, effectively improving production efficiency and ensuring the yield of finished products. If there are four sets of axial sliding components, the servo motor of the first set drives the slider and mold of the first set to move towards the center of the limiting frame 3. The servo motor of the second set drives the slider and mold of the second set to move towards the center of the limiting frame 3. The servo motor of the third set drives the slider and mold of the third set to move towards the center of the limiting frame 3, so that the upper side of the mold of the third set is embedded in the embedding groove on the left side of the mold of the first set, and the lower side is embedded in the embedding groove on the left side of the mold of the second set. The servo motor of the fourth set drives the slider and mold of the fourth set to move towards the center of the limiting frame 3, so that the upper side of the mold of the fourth set is embedded in the embedding groove on the right side of the mold of the first set, and the lower side is embedded in the embedding groove on the right side of the mold of the second set. This makes the four sets of molds fit tightly and restrict each other, so that the mold assembly is accurate and cannot be offset later. The number of axial sliding components can be set according to the actual situation, and can be five or six sets, etc. The specific operation mode can be referred to the above three-set and four-set, so it will not be described in detail in this embodiment.

[0034] After the axial sliding assembly moves into place, the molds thereon are assembled into an integral mold cavity, and the external injection mechanism extends into the mold cavity from the back of the mold base 2, so as to perform die-casting to complete the entire production process. The entire process has a high degree of automation, and the molds are assembled accurately and cannot be displaced subsequently, which effectively improves the production efficiency and ensures the yield of finished products.

[0035] By providing a limiting frame 3 in the middle of the mold base 2, the sliding block and the mold pushed by the servo motor are radially restricted, and the sliding block and the mold move in the limiting frame 3, which effectively prevents the sliding block and the mold from being displaced, and improves the accuracy of the servo motor in conveying the mold. By providing a fixing table on the mold base 2, the position of the servo motor is fixed by the fixing table, so as to effectively prevent the servo motor from being displaced during use, which leads to inaccurate mold conveyance, and further improves the accuracy of the automatic mold clamping mechanism of the die-casting equipment.

[0036] Preferably, as shown in Figures 3 to 6 , the mold is generally in a shape of "convex", and both sides thereof are provided with an engagement groove, which is more conducive to forming a mutually restricted structure after different groups of molds are engaged with each other, so as to effectively prevent the problem of mold displacement during the subsequent injection processing, and ensure the accuracy of the automatic mold clamping mechanism of the die-casting equipment.

[0037] Preferably, as shown in Figures 3 to 5 , the axial sliding assembly further comprises a rotary motor, and the sliding block is provided with a belt set driven by the rotary motor, so that the sliding block and the mold can be driven by the rotary motor to rotate, thereby forming a more precise mold cavity and meeting the production requirements of different products.

[0038] Preferably, as shown in Figures 2 to 5 , the number of the axial sliding assemblies is 4, which are respectively a first axial sliding assembly 4 arranged at the upper part of the mold base 2, a second axial sliding assembly 5 arranged at the lower part of the mold base 2, a third axial sliding assembly 6 arranged at the left end of the mold base 2, and a fourth axial sliding assembly 7 arranged at the right end of the mold base 2.

[0039] For the specific structural arrangement of the first axial sliding assembly 4, as shown in Figures 2 to 6As shown, the first axial sliding assembly 4 includes a first fixed platform 41 disposed on the upper part of the mold frame 2, a first servo motor 42 disposed on the first fixed platform 41 with its output shaft protruding towards the center of the limiting frame 3, a first slider 43 disposed on the output shaft of the first servo motor 42, and a first mold 44 disposed on the outer side of the first slider 43. The first mold 44 has symmetrically formed first fitting grooves 441 on its side. The first servo motor 42 drives the first slider 43 disposed on its output shaft and the first mold 44 disposed on the first slider 43 to move towards the center of the limiting frame 3. By setting a first fixed platform 41 on the mold frame 2 and the first servo motor 42 disposed on the first fixed platform 41, the first servo motor 42 is effectively prevented from shifting during use, thus preventing inaccurate transmission of the first mold 44 and further improving the accuracy of the automatic mold-setting mechanism of this die-casting equipment.

[0040] Regarding the specific structural configuration of the second axial sliding component 5, as follows: Figures 2 to 6 As shown, the second axial sliding assembly 5 includes a second fixed platform 51 disposed at the lower part of the mold frame 2, a second servo motor 52 disposed on the second fixed platform 51 with its output shaft protruding towards the center of the limiting frame 3, a second slider 53 disposed on the output shaft of the second servo motor 52, and a second mold 54 disposed on the outside of the second slider 53. The second mold 54 has symmetrically formed second fitting grooves 541 on its side. The second servo motor 52 drives the second slider 53 disposed on its output shaft and the second mold 54 disposed on the second slider 53 to move towards the center of the limiting frame 3. The second mold 54 can be driven to press against the lower end of the first mold 44, or it can leave a gap with the lower end of the first mold 44 to form a larger mold cavity. Its specific position can be chosen according to the product to be die-cast, so no specific limitation is made in this embodiment. By setting a second fixed platform 51 on the mold frame 2, and setting the second servo motor 52 on the second fixed platform 51, the second servo motor 52 is effectively prevented from shifting during use, which would cause the second mold 54 to be inaccurately conveyed, thereby further improving the accuracy of the automatic mold setting mechanism of this die casting equipment.

[0041] Regarding the specific structural configuration of the third axial sliding component 6, as follows: Figures 2 to 6As shown, the third axial sliding assembly 6 includes a third fixed platform 61 disposed at the left end of the mold frame 2, a third servo motor 62 disposed on the third fixed platform 61 with its output shaft protruding towards the center of the limiting frame 3, a third slider 63 disposed on the output shaft of the third servo motor 62, and a third mold 64 disposed outside the third slider 63. The third mold 64 has symmetrically formed third fitting grooves 641 on its side. After the first axial sliding assembly 4 and the second axial sliding assembly 5 are pushed into place, the third mold 64 is driven by the third servo motor 62. The upper side of the first mold 44 is placed into the first fitting groove 441 at the left end of the first mold 44, and the lower side is placed into the second fitting groove 541 at the left end of the second mold 54. At this time, the side of the first mold 44 is placed into the third fitting groove 641 on the upper side of the third mold 64, and the side of the second mold 54 is placed into the third fitting groove 641 on the lower side of the third mold 64, thereby forming mutual restraint between the first mold 44, the second mold 54, and the third mold 64, effectively preventing the molds from shifting during subsequent injection processing, and ensuring the accuracy of the automatic mold-setting mechanism of this casting equipment. By setting a third fixed platform 61 on the mold frame 2, and setting the third servo motor 62 on the third fixed platform 61, the offset of the third servo motor 62 during use is effectively prevented, which would lead to inaccurate transmission of the third mold 64, further improving the accuracy of the automatic mold-setting mechanism of this die-casting equipment.

[0042] The specific structural configuration of the fourth axial sliding component 7 is as follows: Figures 2 to 6As shown, the fourth axial sliding assembly 7 includes a fourth fixed platform 71 disposed at the right end of the mold frame 2, a fourth servo motor 72 disposed on the fourth fixed platform 71 with its output shaft protruding towards the center of the limiting frame 3, a fourth slider 73 disposed on the output shaft of the fourth servo motor 72, and a fourth mold 74 disposed outside the fourth slider 73. The fourth mold 74 has symmetrically formed fourth fitting grooves 741 on its side. Preferably, after the first axial sliding assembly 4 and the second axial sliding assembly 5 are pushed into place, the fourth axial sliding assembly 7 and the third axial sliding assembly 6 operate simultaneously, thereby improving the production efficiency of the automatic mold-setting mechanism of this die-casting equipment. Driven by the fourth servo motor 72, the upper side of the fourth mold 74 is placed into the first fitting groove 441 at the right end of the first mold 44, and its lower side is placed into the second embedding groove 541 at the right end of the second mold 54. In this design, the side of the first mold 44 is placed into the fourth fitting groove 741 on the upper side of the fourth mold 74, and the side of the second mold 54 is placed into the fourth fitting groove 741 on the lower side of the fourth mold 74. The third mold 64, driven by the third servo motor 62, has its upper side placed into the first fitting groove 441 on the left end of the first mold 44, and its lower side placed into the second fitting groove 541 on the left end of the second mold 54. The side of the first mold 44 is placed into the third fitting groove 641 on the upper side of the third mold 64, and the side of the second mold 54 is placed into the third fitting groove 641 on the lower side of the third mold 64. This forms a structure in which the first mold 44, second mold 54, third mold 64, and fourth mold 74 mutually restrict and cooperate, effectively preventing the molds from shifting during subsequent injection processing and ensuring the accuracy of the automatic mold-setting mechanism of this casting equipment. By setting a fourth fixed platform 71 on the mold frame 2, and setting the fourth servo motor 72 on the fourth fixed platform 71, the fourth servo motor 72 is effectively prevented from shifting during use, which would lead to inaccurate transmission of the fourth mold 74, thereby further improving the accuracy of the automatic mold setting mechanism of this die casting equipment.

[0043] Regarding the specific structural design of the limiting frame 3, as follows: Figures 2 to 7As shown, the limiting frame 3 includes four sets of limiting blocks 31 in a triangular shape, and at least one front limiting plate 32 set on the limiting blocks 31 and matching the shape of the four sets of limiting blocks 31. The four sets of limiting blocks 31 are evenly arranged in the middle of the mold frame 2, and a limiting channel 33 is formed between each pair of them for sliding of the slider and the mold. The servo motor drives the slider and the mold to slide on the limiting channel 33, thereby effectively preventing the slider and the mold from shifting during the process of being driven, ensuring the accuracy of the automatic mold setting mechanism of this die casting equipment. A limiting inspection port 321 is opened in the middle of the front limiting plate 32. People can observe the fitting of each set of molds through the limiting inspection port 321, which is conducive to monitoring the automatic mold setting mechanism of this die casting equipment, discovering abnormalities and taking timely remedial measures, and further improving the yield of the automatic mold setting mechanism of this die casting equipment.

[0044] Preferred, such as Figure 7 As shown, the back of the four sets of limiting blocks 31 are connected by a plate, which effectively prevents the limiting blocks 31 from shifting during use and ensures the accuracy of the automatic mold-setting mechanism of this die-casting equipment.

[0045] Regarding the specific structural configuration of the mold frame 2, as follows: Figures 2 to 5 As shown, the mold frame 2 includes a back plate 21 disposed on the main support 1 and a front plate 22 disposed on the back plate 21. The axial sliding assembly is disposed between the back plate 21 and the front plate 22. The limiting frame 3 is located between the back plate 21 and the front plate 22 and is disposed in the middle of the back plate 21. An injection hole 211 is formed in the middle of the back plate 21. After all the molds are fully fitted, the external injection structure is inserted into the mold cavity through the injection hole 211, thereby die casting and completing the entire production process. A front inspection port 221 is formed in the middle of the front plate 22. The front inspection port 221 can be used to observe the entire limiting frame 3 and the axial sliding assembly, which further facilitates the monitoring of the automatic mold-setting mechanism of this die casting equipment, detects abnormalities and takes timely remedial measures, and further improves the yield of the automatic mold-setting mechanism of this die casting equipment.
