Description

Technical Field

[0001] This utility model relates to the field of die casting mold technology, and more specifically, to a quick-change die casting mold frame for aluminum die casting parts. Background Technology

[0002] Die casting is a casting process. Due to the high cost of casting equipment and molds, die casting is generally used for mass production of large quantities of products. Die casting is particularly suitable for manufacturing a large number of small and medium-sized castings. Die casting is one of the most widely used casting processes. Compared with other casting technologies, die casting has a smoother surface and higher dimensional consistency.

[0003] A search revealed that publication number CN207255196U discloses a die-casting mold guide frame, including a bottom mold, a top mold, and a guiding mechanism. The guiding mechanism is located between the sides of the bottom mold and the top mold. The guiding mechanism includes a mounting frame, a sleeve, a limiting rod, a mounting plate, a pressure sensor, and a displacement sensor. The sleeve is fixedly connected to the side of the top mold via the mounting frame, and the limiting rod, inserted into the sleeve, is mounted to the side of the bottom mold via the mounting frame. When the mold is fully closed for die-casting, if the mold closure is precise, the end of the limiting rod will trigger the pressure sensor. The displacement sensor and the pressure sensor transmit signals to an external microcontroller for processing. If only a displacement signal is present without a pressure signal, it indicates a problem with the mold closure accuracy, allowing for timely adjustments and expanding the functionality and practicality of the die-casting mold guide assembly. The inventors discovered the following problems with the existing technology during the development of this utility model:

[0004] Existing die-casting equipment molds are generally fixed in style due to the large-scale single production. When changing the die-casting mold for aluminum die-casting parts, a large number of tools are often required to disassemble the die-casting mold. The process is very cumbersome and inconvenient to replace, which cannot effectively improve the reuse rate of the equipment.

[0005] Therefore, a quick-change die-casting mold holder for aluminum die-casting parts is proposed to address the above problems. Summary of the Invention

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a quick-change die casting mold holder for aluminum die casting parts to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a quick-change aluminum die-casting mold frame, comprising a base, a die-casting mold, a fixing component and a sliding component, wherein the sliding component is provided above the base, the die-casting mold is provided above the sliding component, and the fixing component is provided on both sides of the die-casting mold respectively.

[0008] Preferably, the sliding assembly includes a sliding groove, a mounting cover, a mounting plate, and a telescopic rod. The mounting cover is slidably disposed above the sliding groove, and the mounting plate is mounted on one side of the mounting cover. The telescopic rod is mounted on the side of the mounting plate away from the mounting cover.

[0009] Preferably, the fixing assembly includes a first connecting rod, a second connecting rod, a connecting shaft, a bolt, a threaded groove, a spring, a fixing post, and a fixing shaft. The bolt is inserted through the threaded groove, and one end of the bolt is connected to the first connecting rod. A second connecting rod is disposed below the first connecting rod, and a connecting shaft is inserted between each group of second connecting rods and the first connecting rod. A spring is disposed on the side of the first connecting rod away from the bolt, and the end of the spring away from the first connecting rod is connected to the fixing post. A fixing shaft is installed in the middle of each group of second connecting rods.

[0010] Preferably, the fixing components are symmetrical about the telescopic rod, and two sets are symmetrically arranged.

[0011] Preferably, the bolt and the threaded groove are connected by an engagement connection, and the first connecting rod and the second connecting rod form a rotating structure through a connecting shaft.

[0012] Preferably, the sliding groove and the mounting cover are connected by a sliding connection, the mounting cover is a semi-enclosed structure, and the mounting cover and the mounting plate are connected by a snap-fit ​​connection.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] Compared with existing technologies, this quick-change aluminum die-casting mold frame, during assembly, initially compresses and fixes the die-casting mold by installing fixing components on both sides of the die-casting mold. Then, by tightening the bolts inside the fixing components, the bolts drive the first connecting rod to be pulled outward. The deformation of the first and second connecting rods fixes the connecting blocks on both sides of the die-casting mold. When disassembling, simply reverse the bolts to restore the deformed first and second connecting rods for quick disassembly.

[0015] Compared with existing technologies, this quick-change aluminum die-casting mold holder uses a telescopic rod to adjust the distance between two sets of fixing components, which can fix die-casting molds of different sizes. The device has a simple structure, and the die-casting mold can be assembled and replaced simply by turning the bolts so that the bolts can move inside the bolt grooves. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0022] As attached Figures 1 to 4 The diagram shows a quick-change aluminum die-casting mold holder, which includes a base 1, a die-casting mold 2, a fixing component 3 and a sliding component 4. The sliding component 4 is provided above the base 1, and the die-casting mold 2 is provided above the sliding component 4. The fixing components 3 are provided on both sides of the die-casting mold 2.

[0023] Specifically: When it is necessary to replace the die-casting mold 2, the clamping of the first connecting rod 9 on the die-casting mold 2 is loosened by turning the bolt 12, and then the two sets of fixing components 3 are separated by the telescopic rod 8 inside the sliding component 4, so that the original die-casting mold 2 can be taken out. When fixing the new die-casting mold 2, the two sets of fixing components 3 are squeezed and fixed by the telescopic rod 8, and then the bolt 12 is turned in the opposite direction to fix it. Example 2

[0024] Based on Example 1, the solution in Example 1 will be further described in detail below with reference to the specific working method, such as... Figures 1 to 4 As shown below, see details:

[0025] In a preferred embodiment, the sliding assembly 4 includes a sliding groove 5, a mounting cover 6, a mounting plate 7, and a telescopic rod 8. The mounting cover 6 is slidably disposed above the sliding groove 5, and the mounting plate 7 is mounted on one side of the mounting cover 6. The telescopic rod 8 is mounted on the side of the mounting plate 7 away from the mounting cover 6. When it is necessary to replace the die-casting mold 2, after the clamping of the connecting blocks on both sides of the die-casting mold 2 inside the fixing assembly 3 is loosened, the telescopic rod 8 is used to push the mounting cover 6 and the mounting plate 7 on both sides to slide inside the sliding groove 5, so that the die-casting mold 2 can be taken out and replaced.

[0026] In a preferred embodiment, the fixing assembly 3 includes a first connecting rod 9, a second connecting rod 10, a connecting shaft 11, a bolt 12, a threaded groove 13, a spring 14, a fixing post 15, and a fixing shaft 16. A bolt 12 is inserted through the threaded groove 13, and one end of the bolt 12 is connected to the first connecting rod 9. A second connecting rod 10 is positioned below the first connecting rod 9, and a connecting shaft 11 is inserted between each set of second connecting rods 10 and the first connecting rod 9. A spring 14 is positioned on the side of the first connecting rod 9 away from the bolt 12, and the end of the spring 14 away from the first connecting rod 9 is connected to the fixing post 15. Each set of second connecting rods 10... Each component has a fixed shaft 16 installed in the middle. When the die-casting mold 2 needs to be replaced, firstly, the bolt 12 on one side of the fixing component 3 is turned to move the bolt 12 inside the screw groove 13, causing the bolt 12 to drive the first connecting rod 9 to move inward. Since each set of second connecting rods 10 has a fixed shaft 16 installed in the middle, the first connecting rod 9 will drive the second connecting rod 10 to deform through the connecting shaft 11. At the same time, the fixed shaft 16 restricts the second connecting rod 10, causing the first connecting rod 9 and the second connecting rod 10 to change from a parallelogram to a rectangle, so that the upper and lower sets of first connecting rods 9 can loosen the clamping of the connecting blocks on both sides of the die-casting mold 2.

[0027] In a preferred embodiment, the fixing components 3 are symmetrical about the telescopic rod 8, and two sets are symmetrically arranged. The two sets of fixing components 3 can not only press and fix the die-casting mold 2 through the mounting cover 6 and the mounting plate 7, but also reinforce both sides of the die-casting mold 2 through the first connecting rod 9, so that the die-casting mold 2 will not move in the mold frame and prevent the impact on the accuracy.

[0028] In a preferred embodiment, the bolt 12 and the threaded groove 13 are connected by an interlocking connection. The first connecting rod 9 and the second connecting rod 10 form a rotating structure through the connecting shaft 11. Since the threaded groove 13 is fixed to the surface of the mounting plate 7, when the bolt 12 is tightened, the bolt 12 will move inside the threaded groove 13, driving the first connecting rod 9 to move. The connecting shaft 11, which is connected to the spring 14, serves to fix and prevent displacement. Since the first connecting rod 9 is connected to the second connecting rod 10 through the connecting shaft 11, when the first connecting rod 9 moves, it will drive the second connecting rod 10 to move simultaneously, changing from a rectangle to a parallelogram to clamp the die-casting mold 2.

[0029] In a preferred embodiment, the sliding groove 5 and the mounting cover 6 are connected by a sliding connection, the mounting cover 6 is a semi-enclosed structure, and the mounting cover 6 and the mounting plate 7 are connected by a snap-fit ​​connection. The mounting cover 6 is a cover-shaped structure. When the mounting cover 6 and the mounting plate 7 are connected, there will be internal space for the first connecting rod 9 and the second connecting rod 10 to move. When there is no impact on the operation, the first connecting rod 9 and the second connecting rod 10 are protected to prevent accidental collisions.

[0030] The working process of this utility model is as follows: First, when the die-casting mold 2 needs to be replaced, the clamping of the first connecting rod 9 on the die-casting mold 2 is loosened by turning the bolt 12. Then, the telescopic rod 8 inside the sliding component 4 drives the two sets of fixing components 3 to separate, so that the original die-casting mold 2 can be taken out. When fixing the new die-casting mold 2, the telescopic rod 8 drives the two sets of fixing components 3 to squeeze and fix the new die-casting mold 2. Then, the bolt 12 is turned in the opposite direction to fix it. When the die-casting mold 2 needs to be replaced, the bolt on one side of the fixing component 3 is turned first. Bolt 12 moves within the threaded groove 13, causing the bolt 12 to move the first connecting rod 9 inward. The first connecting rod 9, through the connecting shaft 11, causes the second connecting rod 10 to deform, changing from a parallelogram to a rectangle. This loosens the clamping of the connecting blocks on both sides of the die-casting mold 2 by the upper and lower sets of the first connecting rods 9. Once the clamping of the connecting blocks on both sides of the die-casting mold 2 is loosened inside the fixing assembly 3, the telescopic rod 8 works to push the mounting covers 6 and mounting plates 7 on both sides to slide within the sliding groove 5, allowing the die-casting mold 2 to be removed and replaced.

[0031] The two sets of fixing components 3 can not only press and fix the die-casting mold 2 through the mounting cover 6 and the mounting plate 7, but also reinforce both sides of the die-casting mold 2 through the first connecting rod 9, so that the die-casting mold 2 will not move in the mold frame and prevent it from affecting the accuracy. When the bolt 12 is tightened, the bolt 12 will move inside the screw groove 13, driving the first connecting rod 9 to move. Since the first connecting rod 9 is connected to the second connecting rod 10 through the connecting shaft 11, when the first connecting rod 9 moves, it will drive the second connecting rod 10 to move at the same time, changing from a rectangle to a parallelogram to clamp the die-casting mold 2. The mounting cover 6 is a cover-shaped structure. When the mounting cover 6 is connected to the mounting plate 7, there will be space inside for the first connecting rod 9 and the second connecting rod 10 to move. When it does not affect the operation, it protects the first connecting rod 9 and the second connecting rod 10 and prevents accidental collisions. The above is the working principle of this quick-change aluminum die-casting mold frame.
