Description

A snap ring punch for a combined die casting machine Technical Field

[0001] This utility model relates to the technical field of circlip punches for die casting machines, specifically a combined circlip punch for die casting machines. Background Technology

[0002] During the operation of a die-casting machine, the snap ring punch is an important component, and its performance and reliability directly affect the quality and efficiency of die-casting production. Currently, in the relevant technologies of snap ring punches for combined die-casting machines, the snap ring is usually directly sleeved on the outer wall of the support base. However, the existing technology lacks an effective fixing structure, which results in the snap ring not being able to be firmly fixed after being installed on the support base.

[0003] During the operation of the punch, due to the lack of reliable fixing measures, the retaining rings are prone to loosening, resulting in gaps. Once gaps appear, high-temperature and high-pressure raw materials can easily enter the gaps during the die casting process. The entry of raw materials into the gaps not only causes wear on the retaining rings but also reduces their structural strength, severely shortening their service life. Frequent replacement of retaining rings not only increases equipment maintenance costs but also leads to production interruptions, reduces production efficiency, and increases the company's operating costs. In addition, loose retaining rings may also affect the working accuracy of the punch, resulting in unstable quality of die-cast parts that cannot meet the ever-increasing production demands. Therefore, there is an urgent need for a combined die-casting machine retaining ring punch that can effectively solve the retaining ring fixing problem, prevent retaining rings from loosening and creating gaps, and avoid raw materials entering the gaps and damaging the retaining rings. Summary of the Invention

[0004] The purpose of this invention is to provide a combined die-casting machine circlip punch to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a combined die-casting machine retaining ring punch, including a support base, a plurality of retaining rings sleeved on the outer wall of the support base, through grooves opened at the four corners of the outer wall of the support base, and limiting grooves opened between the through grooves, limiting blocks slidably connected inside the limiting grooves, an internal top tube fixed inside the limiting block, a square through groove opened on the internal top tube corresponding to the position of the through groove of the support base, a fixing block slidably connected inside the through groove of the support base, a pushing block fixed inside the fixing block, and a driving component provided at the top of the support base.

[0006] Preferably, the bottom end of the push block is an inclined plate, and the push block is located inside the square through groove of the built-in top tube.

[0007] Preferably, the driving component includes a round rod, which is threaded to the inner top end of the built-in top tube, and a connecting seat is fixed to the top end of the round rod.

[0008] Preferably, the outer wall of the round rod matches the thread of the inner wall of the built-in top tube.

[0009] Preferably, the inner wall of the retaining ring has four corners with retaining grooves, and the retaining grooves have the same shape as the fixing block.

[0010] Preferably, when the built-in top tube moves upward, its square through groove contacts the inclined plate below the push block, which can move the fixing block outward and insert it into the inner wall groove of the retaining ring for limiting.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] When installing the retaining ring, simply lay the support flat, put the retaining ring on, and rotate the connecting seat. The internal jacking pipe will move upward through the thread engagement of the round rod with the internal jacking pipe, thereby driving the fixing block to insert into the retaining ring slot and completing the quick assembly. Compared with the traditional retaining ring installation method, it significantly reduces the assembly steps and operation time, greatly improves the assembly efficiency, and reduces labor costs and assembly difficulty.

[0013] The limiting groove and limiting block are designed to precisely limit the upward movement of the built-in jacking tube, ensuring that the square through groove of the built-in jacking tube accurately contacts the pushing block. This allows the fixing block to be accurately embedded into the jacking ring groove, achieving a stable snap-fit ​​fixation. This precise limiting and fixing method effectively avoids the jacking ring from shifting or misaligning during installation, ensuring the accuracy and stability of the jacking ring installation, and thus improving the reliability of the entire jacking ring punch during operation.

[0014] Once the fixing block is fully embedded in the retaining ring groove, it can tightly fill the potential gap between the retaining rings, effectively preventing raw materials from entering the retaining ring gaps during the die casting process. This not only avoids retaining ring wear caused by raw materials entering the gaps, but also prevents problems such as retaining ring loosening and displacement that may be caused by the presence of gaps. This significantly extends the service life of the retaining rings, reduces the frequency of equipment maintenance and retaining ring replacement, lowers equipment operating costs, and ensures the continuity of die casting production and product quality.

[0015] A clever mechanical linkage structure is formed between the built-in jacking pipe, the pushing block, and the fixing block. When the built-in jacking pipe moves upward, it automatically pushes the pushing block outward through the contact between the square through slot and the inclined side of the pushing block, thereby driving the fixing block to insert into the retaining ring slot. No additional complex drive device is required, simplifying the overall structure. This mechanical linkage design not only improves the automation level of the device, but also reduces the potential failure points caused by too many parts, enhances the stability and reliability of the equipment operation, and reduces the manufacturing and maintenance costs of the equipment.

[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.

[0022] Please refer to Figures 1-4. This utility model provides a technical solution for a combined die-casting machine retaining ring punch: A combined die-casting machine retaining ring punch includes a support base 1. Multiple retaining rings 2 are sleeved on the outer wall of the support base 1. The support base 1 serves as the basic load-bearing component of the entire retaining ring punch, ensuring that the built-in top tube 4 moves in the correct direction during the upward process and ensuring the matching accuracy between the components. Through grooves are opened at the four corners of the outer wall of the support base 1, and limit grooves are opened between the through grooves. Limiting blocks 3 are slidably connected inside the limit grooves. The limit blocks 3 are made of wear-resistant engineering plastic or metal, and their shape is adapted to the limit grooves, allowing them to slide freely within the limit grooves. The built-in top tube 4 is fixed inside the limit block 3. The built-in top tube 4 is one of the core transmission components for realizing the retaining ring fixing and disassembly functions, and the built-in top tube 4 can move up and down along an accurate path, ensuring the transmission accuracy between it and other components. A square through groove is opened on the built-in top tube 4 at the position where the through grooves are opened on the support base 1. A fixing block 5 is slidably connected inside the through grooves of the support base 1. The fixing block 5 is used to realize the retaining ring 2 The fixed direct actuator achieves the limiting and fixing of the retaining ring 2 through the tight fit between the retaining groove and the fixed retaining block 5. The inner side of the fixed retaining block 5 is fixed with a pushing block 6. The pushing block 6 is the key conversion component that converts the vertical movement of the built-in jacking pipe 4 into the horizontal movement of the fixed retaining block 5. At the same time, in order to further improve the movement stability and wear resistance of the pushing block 6, its surface in contact with the inner wall of the square through groove is polished and wear-resistant. The top of the support base 1 is provided with a driving component, which consists of a round rod 7 and a connecting seat 8. It is the power source for realizing the up and down movement of the built-in jacking pipe 4. The bottom end of the pushing block 6 is an inclined plate, and the pushing block 6 is located inside the square through groove of the built-in jacking pipe 4.

[0023] The driving component includes a round rod 7, which is threaded to the inner top of the built-in jacking tube 4. A connecting seat 8 is fixed to the top of the round rod 7. When the connecting seat 8 is rotated, the round rod 7 will rotate accordingly. Due to the threaded transmission relationship between the round rod 7 and the built-in jacking tube 4, the threads of the outer wall of the round rod 7 match those of the inner wall of the built-in jacking tube 4. The inner wall of the retaining ring 2 has four corner slots. After the retaining ring 2 is inserted into the retaining ring 2 by the fixing block 7, it can fix and engage the retaining ring 2 to prevent gaps from appearing between the retaining rings 2 during use, which would allow raw materials to enter the gaps. Moreover, the retaining rings and the fixing blocks 5 have the same shape. When the built-in jacking tube 4 moves upward, its square through slot contacts the inclined plate below the pushing block 6, which can move the fixing block 5 outward and insert it into the retaining ring 2's inner wall slot for limiting.

[0024] Working Principle: When using a combination die-casting machine's retaining ring punch, if the retaining ring 2 needs to be installed, place the support base 1 flat on the ground, then fit the retaining ring 2 onto the outer wall of the support base 1. Next, insert the connecting seat 8 into the support base 1 via the round rod 7, contacting the built-in top tube 4. Then rotate the connecting seat 8; as it rotates, the round rod 7 engages with the built-in top tube 4 via threads, causing the connecting seat 8 to move downwards until it fits against the top of the support base 1. Then rotate the connecting seat 8 again; as it rotates, the round rod 7 pulls the built-in top tube 4 upwards. When the tube 4 moves upward, the limiting block 3 can limit the movement of the built-in jacking tube 4. During the upward movement of the built-in jacking tube 4, the square through groove contacts the inclined edge of the bottom of the pushing block 6, pushing the fixing block 5 outward. When the fixing block 5 moves outward, it is embedded in the inside of the retaining ring 2 to limit and lock the retaining ring 2. When the connecting seat 8 rotates, it cannot continue to rotate due to resistance. The fixing block 5 is completely embedded in the inside of the retaining ring 2. The limiting and locking of the fixing block 5 can effectively prevent gaps from appearing between the retaining rings 2 during use of the punch, which would cause raw materials to enter the gaps and cause wear and damage to the retaining rings.
