Description

Technical Field

[0001] This utility model relates to the field of auxiliary components for die casting molds, specifically to a die casting mold locking mechanism. Background Technology

[0002] In the die-casting production process, the clamping mechanism is a key component of the die-casting mold, and its performance directly affects the quality of the die-cast products, production efficiency, and the service life of the mold. Currently, most die-casting molds on the market use a traditional tie-rod type clamping mechanism.

[0003] Traditional tie-rod type mold locking structures typically use multiple tie rods and nuts to achieve mold locking. However, during the mold locking process, this structure suffers from uneven force distribution on the tie rods, which can easily lead to gaps on the mold parting surface. This can result in defects such as flash and burrs on the die-cast products, affecting product quality. Furthermore, adjusting the locking force of the tie-rod type mold locking structure is cumbersome and difficult to precisely control, making it less adaptable to die-cast products of different specifications and materials. Utility Model Content

[0004] The purpose of this utility model is to provide a die-casting mold locking mechanism to solve the above problems, as detailed below.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] The die-casting mold locking mechanism provided by this utility model includes a die-casting platform body, a fixed mold body and a moving mold body. The die-casting platform body is arranged horizontally, the fixed mold body is fixed in the middle of the top surface of the die-casting platform body, and the moving mold body is pressed against the top of the fixed mold body, so as to form a complete die-casting mold structure by means of the moving mold body and the fixed mold body.

[0007] The die-casting platform body is equipped with mold-locking drive components at all four corners. The mold-locking drive components on the same side are connected by a locking support plate via a moving limit component. The locking support plate is first adjusted to be above the top side of the moving mold body by the moving limit component. Then, the locking support plate is lowered by the mold-locking drive component to lock the moving mold body and the fixed mold body after mold closing.

[0008] The locking support plate assembly is equipped with multiple reinforced mold-locking components, which are used to perform mold-closing and locking operations on the moving mold body and the fixed mold body at multiple points during the process of the locking support plate being pulled down.

[0009] Preferably, each of the mold-locking drive components includes a hydraulic cylinder body and a hydraulic rod. The hydraulic cylinder body is vertically fixed at each of the four corners of the top surface of the die-casting platform body. The hydraulic cylinder body is coaxially provided with an upwardly extending hydraulic rod that can reciprocate. The top of each hydraulic rod is fixedly mounted with a horizontally oriented guide wing plate by a mounting sleeve. The ends of the guide wing plates on both sides extend beyond the side corresponding to the fixed mold body. The guide wing plates on the same side are combined with a moving limit component, and the moving limit components on the same side are fixed with a longitudinally oriented locking support plate.

[0010] Preferably, the hydraulic cylinder body and the guide vane at the front position are located in front of the front end face of the moving mold body and the fixed mold body, and the hydraulic cylinder body and the guide vane at the rear position are located behind the rear end face of the moving mold body and the fixed mold body.

[0011] Preferably, each of the moving limiting components includes an idle limiting hole, a usage limiting hole, and a mating sleeve. The top surface of the guide wing plate has the idle limiting hole and the usage limiting hole vertically opened on the side near the corresponding hydraulic cylinder body and the side away from the corresponding hydraulic cylinder body, respectively. The mating sleeve is fitted on the outside of each guide wing plate in a lateral sliding fit. The locking support plate is fixed longitudinally between the mating sleeves at the front and rear positions on the same side. At the same time, the locking support plate is suspended above the corresponding side of the top surface of the moving mold body. The top surface of each mating sleeve has a vertical mounting hole, and the mounting holes are all through holes. The mounting holes are vertically inserted with a limiting rod in a sliding fit. The bottom end of each limiting hole is coaxially slidingly fitted with the corresponding usage limiting hole.

[0012] Preferably, each of the limiting rods has a handle coaxially fixed to its top end, and the portion of the limiting rod located between the bottom of the corresponding handle and the top surface of the mating sleeve is coaxially fitted with a spring in a clearance fit manner, and the two ends of the spring are respectively fixedly connected to the corresponding handle and the mating sleeve.

[0013] Preferably, the guide vanes are all horizontally placed rectangular strips, and when the mating sleeve moves to the point where the limiting rod is vertically aligned with the idle limiting hole, the locking support plate moves to a point where it is completely offset from the top surface of the moving mold body.

[0014] Preferably, each of the reinforced locking components includes a mating hole and a clamping stud. The top surface of each locking support plate is vertically provided with multiple mating holes, and the multiple mating holes on the same side are located in the same longitudinal direction. Each mating hole is vertically inserted with a clamping stud in a threaded manner, and the bottom end of each clamping stud is coaxially fixed with a pressure plate. At the same time, the bottom surface of each pressure plate is covered and fixed with an elastic pad of buffer material.

[0015] Preferably, both the pressure plate and the elastic pad are circular plates, and both elastic pads are rubber plates.

[0016] Preferably, each of the clamping studs is fitted with a handle at its top for easy gripping.

[0017] Preferably, the portion of the clamping stud extending beyond the top surface of the locking support plate is coaxially engaged with a locking nut.

[0018] In practical application, the die-casting mold locking mechanism described above utilizes a method where the mold-locking drive assembly is positioned at each of the four corners of the die-casting platform body. Furthermore, the locking support plate is connected to the front and rear of each mold-locking drive assembly on the same side via the moving limit assembly. First, the moving limit assembly adjusts the locking support plate to a position above the top side of the moving mold body. Then, the mold-locking drive assembly lowers the locking support plate, enabling it to perform a locking operation on the moving mold body and the fixed mold body after mold closing. This locking method is simple and easy to implement. Furthermore, this design improves applicability. Since each locking plate is equipped with multiple reinforced locking components, during the downward pulling of the locking plate, the elastic pads of the reinforced locking components deform and press against the top surface of the moving mold body. This ensures multi-point locking of the moving and fixed mold bodies, enhancing mold-locking stability. Simultaneously, by tightening the clamping studs, the corresponding elastic pads are pressed against the top surface of the moving mold body, facilitating fine-tuning of the elastic pads to ensure stable locking of the moving mold body. Because the locking plate can be moved to a position above the top side of the moving mold body and locked by the sliding of the sleeve of the moving limiting assembly along the guide wing plate and the vertical sliding engagement of the limiting rod with the use limiting hole, the locking plate can be moved to a position above the top side of the moving mold body. This facilitates the locking operation of the moving mold body and the fixed mold body after the locking plate and the reinforced mold locking assembly are pulled down. At the same time, the locking plate can be limited in displacement by the sliding of the sleeve of the moving limiting assembly along the guide wing plate and the vertical sliding engagement of the limiting rod with the idle limiting hole. The locking plate is moved until it is completely offset from the top surface of the moving mold body and locked, thereby facilitating the opening operation of the moving mold body and the fixed mold body after the locking plate and the reinforcing mold locking assembly are moved away from the top of the moving mold body. Since the mating sleeve can slide laterally along the guide wing plate and be disengaged from the outer end after the bottom end is pulled up by the limiting rod, the locking plate can be removed from the mold locking drive assembly at the front and rear positions. The method of removing the locking plate is simple and easy to operate, which facilitates the subsequent inspection and maintenance of the locking plate and the reinforcing mold locking assembly after removal.

[0019] The beneficial effects are as follows: 1. The present invention has a mold-locking drive assembly assembled at each of the four corners of the die-casting platform body, and a locking support plate is assembled between the front and rear of the mold-locking drive assembly on the same side by means of a moving limit assembly. Then, the locking support plate is first adjusted to be located above the top side of the moving mold body by means of the moving limit assembly, and then the locking support plate is driven down by the mold-locking drive assembly, so that the locking support plate can perform the locking operation on the moving mold body and the fixed mold body after mold closing. The locking method is simple and easy to implement, and improves applicability.

[0020] 2. The locking plate is equipped with multiple reinforcing locking components. When the locking plate is pulled down, the elastic pads of the reinforcing locking components deform and press against the top surface of the moving mold body. This ensures that the moving mold body and the fixed mold body are locked at multiple points, which helps to improve the stability of the locking. At the same time, by turning the clamping studs, the corresponding elastic pads can be pressed against the top surface of the moving mold body, which makes it easy to fine-tune the elastic pads to ensure stable clamping and locking of the moving mold body.

[0021] 3. By sliding the mating sleeve of the movable limiting component laterally along the guide wing plate and vertically sliding the limiting rod with the limiting hole, the locking support plate can be moved to the top side of the moving mold body and locked, which facilitates the locking operation of the moving mold body and the fixed mold body after the locking support plate and the reinforcing locking assembly are pulled down.

[0022] 4. By sliding the matching sleeve of the movable limiting component laterally along the guide wing plate and vertically sliding the limiting rod with the idle limiting hole, the locking support plate can be moved to be completely offset from the top surface of the moving mold body and locked. This makes it easier to move the locking support plate and the reinforcing locking component away from the top of the moving mold body so as to smoothly open the moving mold body and the fixed mold body.

[0023] 5. Simply pull up the limit rod to retract the bottom end into the mounting hole, and the mating sleeve can slide laterally along the guide wing plate until it comes off from the outer end. This allows the locking support plate to be removed from the locking mold drive assembly at the front and rear positions. The method of removing the locking support plate is simple and easy to operate, which facilitates subsequent inspection and maintenance of the locking support plate and the reinforcing locking assembly after removal.

[0035] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0036] See Figures 1-8As shown, this utility model provides a die-casting mold locking mechanism, including a die-casting platform body 2, a fixed mold body 7, and a moving mold body 6. The die-casting platform body 2 is arranged horizontally, the fixed mold body 7 is fixed in the middle of the top surface of the die-casting platform body 2, and the moving mold body 6 is pressed against the top of the fixed mold body 7, so as to form a complete die-casting mold structure with the help of the moving mold body 6 and the fixed mold body 7. Each of the four corners of the die-casting platform body 2 is equipped with a mold-locking drive assembly 1. Locking support plates 4 are connected to each mold-locking drive assembly 1 on the same side via a moving limit assembly 3. This allows the locking support plates 4 to be adjusted to a position above the top side of the moving mold body 6 via the moving limit assembly 3. Then, the locking support plates 4 are lowered by the mold-locking drive assembly 1 to lock the moving mold body 6 and the fixed mold body 7 after mold closing. Specifically, each mold-locking drive assembly 1 includes a hydraulic cylinder body 104 and a hydraulic rod 103. A hydraulic cylinder body 104 is vertically fixed at each of the four corners of the top surface of the die-casting platform body 2. Each hydraulic cylinder body 104 has an upwardly extending and reciprocating hydraulic rod 103 coaxially mounted on it. A horizontally oriented guide wing plate is fixedly mounted on the top of each hydraulic rod 103 via an mounting sleeve 102. 101, and the ends of the guide vanes 101 on both sides extend beyond the corresponding side of the fixed mold body 7. The guide vanes 101 on the same side are all equipped with a moving limit assembly 3, and a locking support plate 4 is fixed between the moving limit assemblies 3 on the same side. The purpose of this arrangement is that the locking support plate 4 is first adjusted to be above the top side of the moving mold body 6 by the moving limit assembly 3, and then the locking support plate 4 is lowered by the locking mold drive assembly 1 so that the locking support plate 4 can perform the locking operation on the moving mold body 6 and the fixed mold body 7 after mold closing. The locking method is simple and easy to implement. More specifically, the pulling down and lifting of the locking support plate 4 is achieved by the hydraulic cylinder body 104 driving the hydraulic rod 103. It should be noted that the hydraulic cylinder bodies 104 at the front and rear positions on the same side should be synchronous hydraulic cylinders.

[0037] See Figures 1-8As shown, each of the moving limiting components 3 includes an idle limiting hole 302, a usage limiting hole 307, and a mating sleeve 304. The top surface of the guide wing plate 101 has an idle limiting hole 302 and a usage limiting hole 307 vertically opened on the side near the corresponding hydraulic cylinder body 104 and the side away from the corresponding hydraulic cylinder body 104, respectively. The outer surface of the guide wing plate 101 is fitted with a mating sleeve 304 in a transverse sliding fit. The mating sleeves 304 at the front and rear positions on the same side are all fixed with locking plates 4 horizontally along the longitudinal direction. At the same time, the locking plates 4 are all suspended above the corresponding side of the top surface of the moving mold body 6. Each of the mating sleeves 304 has vertically protruding mounting holes 306 on its top surface, and all mounting holes 306 are through holes. Limiting rods 305 are vertically inserted through each mounting hole 306 in a sliding fit. The bottom end of each limiting hole is coaxially slidingly fitted with a corresponding use limiting hole 307. A handle 301 is coaxially fixed to the top of each limiting rod 305. A spring 303 is coaxially fitted to the portion of the limiting rod 305 between the bottom of the corresponding handle 301 and the top surface of the mating sleeve 304 in a clearance fit. Both ends of the spring 303 are fixedly connected to the corresponding handle 301 and the mating sleeve 304, respectively. The purpose of this arrangement is that, firstly, by sliding the mating sleeve 304 of the movable limiting component 3 laterally along the guide wing plate 101 and vertically sliding the limiting rod 305 with the use limiting hole 307, the locking support plate 4 can be limited to move to the top side of the moving mold body 6 and locked. This facilitates the locking operation of the moving mold body 6 and the fixed mold body 7 after the locking support plate 4 and the reinforcing mold locking component 5 are pulled down. At the same time, by sliding the mating sleeve 304 of the movable limiting component 3 laterally along the guide wing plate 101 and vertically sliding the limiting rod 305 with the idle limiting hole, the locking support plate 4 can be limited to move to the top side of the moving mold body 6 and locked. This makes it easier for the locking support plate 4 and the reinforcing mold locking component 5 to perform the locking operation after the mold is closed. The vertical sliding fit of 302 allows the locking support plate 4 to be moved to a position completely offset from and locked from the top surface of the moving mold body 6. This facilitates the smooth opening of the moving mold body 6 and the fixed mold body 7 after the locking support plate 4 and the reinforcing mold locking assembly 5 are moved away from the top of the moving mold body 6. Moreover, by simply pulling up the limiting rod 305 to allow the bottom end to be inserted into the mounting hole 306, the mating sleeve 304 can slide laterally along the guide wing plate 101 until it is dislodged from the outer end. This allows the locking support plate 4 to be removed from the mold locking drive assembly 1 at the front and rear positions. The method of removing the locking support plate 4 is simple and easy to operate.

[0038] See Figures 1-6As shown, the locking support plate 4 is equipped with multiple reinforcing mold-locking components 5, which are used to perform multi-point mold-locking operations on the moving mold body 6 and the fixed mold body 7 during the process of the locking support plate 4 being pulled down. Each reinforcing mold-locking component 5 includes a mating hole 506 and a clamping stud 502. The top surface of the locking support plate 4 is vertically provided with multiple mating holes 506, and the multiple mating holes 506 on the same side are located in the same longitudinal direction. Each mating hole 506 is vertically inserted with a clamping stud 502 by thread engagement, and the bottom end of each clamping stud 502 is coaxially fixed with a pressure plate 504. At the same time, the pressure plate The bottom surface of 504 is covered with elastic pads 505 of buffer material. The reason for this setting is that when the locking support plate 4 is pulled down, the elastic pads 505 of the mold clamping assembly 5 deform and press against the top surface of the moving mold body 6, which can ensure that the moving mold body 6 and the fixed mold body 7 are clamped at multiple points, which is beneficial to improving the stability of mold clamping. At the same time, by turning the clamping stud 502, the corresponding elastic pads 505 can be pressed against the top surface of the moving mold body 6, which makes it easy to fine adjust the elastic pads 505 to ensure stable clamping and mold clamping operation of the moving mold body 6.

[0039] See Figures 1-8 As shown, the following optimizations have been made to this application: the hydraulic cylinder body 104 and guide wing plate 101 at the front position are both located in front of the front end face of the moving mold body 6 and the fixed mold body 7, and the hydraulic cylinder body 104 and guide wing plate 101 at the rear position are both located behind the rear end face of the moving mold body 6 and the fixed mold body 7. This arrangement helps to avoid the hydraulic cylinder body 104 and guide wing plate 101 interfering with the smooth mold closing and opening process of the moving mold body 6 and the fixed mold body 7. Optionally, the guide wing plates 101 are all horizontally placed rectangular strips, and when the mating sleeve 304 moves to the point where the limiting rod 305 is vertically aligned with the idle limiting hole 302, the locking support plate 4 moves to be completely offset from the top surface of the moving mold body 6. This arrangement ensures that the mating sleeve 304 can drive the locking support plate 4 to move to be completely offset from the top surface of the moving mold body 6, thereby smoothly realizing the mold opening process.

[0040] See Figures 1-8As shown, both the pressure plate 504 and the elastic pad 505 are circular plates, and the elastic pad 505 is made of rubber, so that the elastic pad 505 has good elastic buffering capacity, which can deform and press against the top surface of the moving mold body 6 while avoiding damage to the top surface of the moving mold body 6. Further optionally, the top of each clamping stud 502 is equipped with a handle 501 for easy gripping, so that the clamping stud 502 can be turned by applying force by gripping the handle 501. Furthermore, the portion of the clamping stud 502 extending out of the top surface of the locking support plate 4 is coaxially engaged with a locking nut 503. With this configuration, after the clamping stud 502 is turned to press the elastic pad 505 against the moving mold body 6, the locking nut 503 is tightened to press against the top surface of the locking support plate 4, thus preventing the clamping stud 502 from rotating naturally. Subsequently, it is only necessary to repeatedly pull the locking support plate 4 down with the hydraulic cylinder body 104 with a fixed stroke. In this way, the locking support plate 4 and the reinforced mold-locking assembly 5 can perform repeated and stable mold-locking operations after the fixed mold body 7 is closed.

[0041] With the above structure, in practical use, since mold-locking drive components 1 are assembled at the four corners of the die-casting platform body 2, and locking support plates 4 are assembled between the front and rear of the mold-locking drive components 1 on the same side via moving limit components 3, the locking support plates 4 are first adjusted to be above the top side of the moving mold body 6 by the moving limit components 3, and then the locking support plates 4 are lowered by the mold-locking drive components 1, so that the locking support plates 4 can perform the locking operation on the moving mold body 6 and the fixed mold body 7 after mold closing. The locking method is simple and easy to implement, and improves applicability. Multiple reinforcing mold-locking components 5 are assembled and installed on each mold-locking support plate. During the downward pulling of the locking support plate 4, the elastic pads 505 of the reinforcing mold-locking components 5 deform and press against the top surface of the moving mold body 6. This ensures multi-point mold-locking operation of the moving mold body 6 and the fixed mold body 7, improving mold-locking stability. Simultaneously, by tightening the clamping studs 502, the corresponding elastic pads 505 are pressed against the top surface of the moving mold body 6, facilitating fine-tuning of the elastic pads 505 to ensure stable clamping and locking of the moving mold body 6. Furthermore, due to the movement limit... The mating sleeve 304 of the positioning component 3 slides laterally along the guide wing plate 101 and slides vertically with the limit rod 305 and the use limit hole 307, which allows the locking support plate 4 to be limited to move above the top side of the moving mold body 6 and locked. This facilitates the locking operation of the moving mold body 6 and the fixed mold body 7 after the locking support plate 4 and the reinforcing mold locking component 5 are pulled down. At the same time, the mating sleeve 304 of the moving limit component 3 slides laterally along the guide wing plate 101 and slides vertically with the limit rod 305 and the idle limit hole 302, which allows the locking support plate 4 to be limited to move. The locking plate 4 is completely offset from and locked to the top surface of the moving mold body 6, so that the locking plate 4 and the reinforcing mold locking assembly 5 can be moved away from the top of the moving mold body 6 to facilitate the mold opening operation of the moving mold body 6 and the fixed mold body 7. Since only the limit rod 305 needs to be pulled up to make the bottom end retract into the mounting hole 306, the mating sleeve 304 can slide laterally along the guide wing plate 101 until it is dislodged from the outer end. This allows the locking plate 4 to be removed from the mold locking drive assembly 1 at the front and rear positions. The method of removing the locking plate 4 is simple and easy to operate, which facilitates the subsequent inspection and maintenance of the locking plate 4 and the reinforcing mold locking assembly 5 after removal.

[0042] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
