Description

Technical Field

[0001] This utility model relates to the field of die casting mechanism technology, specifically a die casting mechanism for a die casting machine with precise alignment. Background Technology

[0002] Die casting is a metal casting process, and aluminum alloy products are also commonly made using die casting. Its characteristic is that high pressure is applied to molten metal using a mold cavity. The mold is usually made of a higher strength alloy. This process is somewhat similar to injection molding. Die casting equipment and molds are expensive, so die casting is generally only 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, so it is the most widely used of various casting processes.

[0003] The prior art, disclosed in CN221047267U, provides a die-casting mechanism for a die-casting machine with precise alignment. The mechanism includes a main body with an internal mounting groove. Sliding grooves are provided on both the left and right side walls of the mounting groove. A fixing plate is fixedly installed at the bottom of the sliding groove, and a die is fixedly installed on the top of the fixing plate. Two sets of symmetrically distributed sliding rods are fixedly installed at the four corners of the top of the fixing plate, with the tops of the sliding rods connected to the top of the mounting groove. This die-casting mechanism for a die-casting machine with precise alignment includes a die-casting box. During die-casting, the box door is opened, the die-casting material is placed on the die, the box door is closed, and the mounting plate is pushed down by a cylinder in the die-casting mechanism. The die-casting material is then pressed into the die by the punch, thus completing the die-casting process. Simultaneously, the die-casting box blocks the debris generated during the die-casting process, effectively preventing debris from splashing and causing injury to workers.

[0004] The aforementioned patent mainly achieves precise alignment of the punch and die by fixing the fixed plate and the die and using pulleys to limit their movement within the groove. However, since the die is fixedly mounted on the fixed plate, the user cannot replace it, which means that the die casting machine can only perform die casting on molds of a single shape, thus reducing the applicability of the die casting machine to various types of molds. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a die-casting mechanism for a die-casting machine with precise alignment, thus solving the above-mentioned technical problems.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a die-casting mechanism for a precision-aligned die-casting machine, comprising a body, a swinging assembly for preventing debris splashing mounted at the front end of the body, a control assembly for controlling the die-casting process mounted on the body, an outer wall, a hydraulic cylinder mounted movably with its top facing downwards on the outer wall, a die-casting assembly disposed within the outer wall, the die-casting assembly comprising a column fixedly mounted on the top of the outer wall, a bottom assembly fixedly mounted on the bottom of the column, a lower mold assembly detachably mounted on the bottom assembly, and a movable assembly moving on the column, an upper mold assembly detachably mounted on the end of the movable assembly near the lower mold assembly, and a fixed end of the movable assembly away from the upper mold assembly mounted on the telescopic end of the hydraulic cylinder. The fixed mounting of the end of the movable assembly away from the upper mold assembly on the telescopic end of the hydraulic cylinder allows the extension and retraction of the hydraulic cylinder to directly move the movable assembly, improving the integrated operation of the internal structure of the precision-aligned die-casting mechanism.

[0007] Furthermore, the bottom assembly includes a lower plate with a cylindrical groove at its top center, a movable groove at the center of the cylindrical groove, and a straight groove at the top of the cylindrical groove. The centerline of the cylindrical groove and the centerline of the hydraulic cylinder are collinear. This alignment ensures precise positioning of the upper and lower mold assemblies during hydraulic cylinder movement, improving the operational accuracy of the die-casting mechanism in the die-casting machine.

[0008] Furthermore, the lower mold assembly includes a lower mold for placing the die-cast part. An insertion post is fixedly installed at the center of one end of the lower mold near the lower plate. A straight bar is installed at the center of the insertion post. The size of the straight bar is adapted to the straight bar groove, and the size of the insertion post is adapted to the cylindrical groove. The straight bar moves within the movable groove. When the straight bar moves within the movable groove, such that the straight bar and the straight bar groove are not on the same straight line, the lower mold cannot be removed from the lower plate, thus improving the stability of the internal structure of the die-casting mechanism for precise alignment.

[0009] Furthermore, an arc groove is provided at the center of both sides of the outer wall, and the movable component includes a movable plate that moves on the column. Fixed shafts are fixedly installed on both sides of the movable plate, and rotating balls are rotatably installed on the fixed shafts. The rotating balls move within the arc grooves.

[0010] Furthermore, the control assembly includes a controller fixedly mounted on one side of the outer wall, and a driver fixedly mounted on the top of the outer wall. The driver is connected to the hydraulic cylinder and is used to drive the hydraulic cylinder's movement. A connecting wire connects the driver to the controller, and the controller and driver are electrically connected. This electrical connection allows the controller to directly control the driver, improving the intelligence of the die-casting mechanism in the die-casting machine, ensuring precise alignment.

[0011] Furthermore, the swing assembly includes an aluminum alloy door with an observation window at its center and a handle for facilitating the swinging of the aluminum alloy door fixedly installed on the side of the aluminum alloy door away from the control assembly.

[0012] Furthermore, the rotating ball is made of stainless steel. The wear-resistant stainless steel ball allows for long-term contact between the ball and the arc groove on the outer wall without significant wear, thus extending the service life of the die-casting mechanism in a precision die-casting machine. Beneficial effects

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] This invention designs the lower mold for placing die-cast parts to be quickly disassembled from the lower plate, and similarly, the upper mold assembly for the lower die-casting part is designed to be quickly disassembled from the movable assembly. This allows the die-casting mechanism for a precisely aligned die-casting machine to allow users to easily replace the upper and lower molds while ensuring precise die-casting, thus improving the applicability of the precisely aligned die-casting mechanism to various molds.

[0022] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the protection scope of this utility model.

[0023] Example

[0024] The following is in conjunction with the appendix Figure 1 - Appendix Figure 6This application provides a further detailed description. A die-casting mechanism for a precision die-casting machine includes a body 2. A swinging assembly 3 for preventing debris splashing is mounted on the front end of the body 2. A control assembly 1 for controlling the die-casting process is mounted on the body 2. The body 2 includes an outer wall 22. A hydraulic cylinder 14 is movably mounted on the top of the outer wall 22. A die-casting assembly 23 is disposed inside the outer wall 22. The die-casting assembly 23 includes a column 231 fixedly mounted on the top of the outer wall 22. A bottom assembly 233 is fixedly mounted on the bottom of the column 231. A lower mold assembly 234 is detachably mounted on the bottom assembly 233. The die-casting assembly 23 also includes a movable assembly 232 that moves on the column 231. The upper mold assembly 235 is detachably mounted at one end near the lower mold assembly 234. The movable assembly 232 is fixedly mounted at the telescopic end of the hydraulic cylinder 14 at the end away from the upper mold assembly 235. The bottom assembly 233 includes a lower plate 2334. A cylindrical groove 2333 is formed at the center of the top of the lower plate 2334. A movable groove 2332 is formed at the center of the cylindrical groove 2333. A straight groove 2331 is formed at the top of the cylindrical groove 2333. The centerline of the cylindrical groove 2333 is on the same straight line as the centerline of the hydraulic cylinder 14. The lower mold assembly 234 includes a lower mold 2341 for placing the die-casting part. An insertion post 2343 is fixedly installed at the center of one end of the lower mold 2341 near the lower plate 2334. A straight bar 2342 is installed at the center of the insertion post 2343. The size of the straight bar 2342 is adapted to the straight bar groove 2331. The size of the insertion post 2343 is adapted to the cylindrical groove 2333. The straight bar 2342 moves within the movable groove 2332. Arc grooves 21 are formed at the center of both sides of the outer wall 22. The movable component 232 includes a movable plate 2321 that moves on the column 231. Fixed shafts 2323 are fixedly installed on both sides of the movable plate 2321. Rotating balls 2322 are rotatably installed on the fixed shafts 2323. The rotating balls 2322 move within the arc grooves. The inner limit movement of 21 includes a controller 13 fixedly installed on one side of the outer wall 22, and a driver 11 fixedly installed on the top of the outer wall 22. The driver 11 is connected to a hydraulic cylinder 14 and is used to drive the hydraulic cylinder 14 to move. A connecting wire 12 is connected to the driver 11 and the controller 13. The controller 13 is electrically connected to the driver 11. The swing component 3 includes an aluminum alloy door 31. An observation window 32 is opened in the center of the aluminum alloy door 31. A handle 33 for facilitating the swing of the aluminum alloy door 31 is fixedly installed on the side of the end of the aluminum alloy door 31 away from the control component 1. The rotating ball 2322 is made of stainless steel.

[0025] The actuator 11 is connected to the hydraulic cylinder 14. The hydraulic cylinder 14 operates based on Pascal's principle, which describes the transmission of pressure in a closed container. A hydraulic pump forces hydraulic oil into the inlet of the hydraulic cylinder, pushing the piston to the other end of the cylinder, thus achieving linear motion. By adjusting the flow rate and pressure of the hydraulic oil, the piston's speed and force can be controlled. Therefore, the actuator 11 directly drives the hydraulic cylinder 14. Furthermore, since the actuator 11 is connected to the controller 13 via cable 12, the controller 13 can directly control the extension and retraction of the hydraulic cylinder 14.

[0026] Since the lower mold assembly 234 is located at the center of the bottom assembly 233 and the upper mold assembly 235 is located at the center of the movable assembly 232, and since the up and down movement of the movable assembly 232 is limited by the column 231 and by the movement of the rotating ball 2322 in the arc groove 21, the die casting mechanism of the die casting machine with precise alignment can perform high-precision alignment die casting.

[0027] The lower mold assembly 234 and the upper mold assembly 235 are used to place the die casting parts. The lower mold assembly 234 and the upper mold assembly 235 can be disassembled relative to the lower plate 2334 and the movable plate 2321. Therefore, users can replace and install various types of lower mold assemblies 234 and upper mold assemblies 235, which improves the applicability of the die casting mechanism for die casting machines with precise alignment.

[0028] Since the straight bar 2342 and the insertion post 2343 can be inserted into the straight bar groove 2331 and the cylindrical groove 2333, and when the straight bar 2342 is located in the movable groove 2332, rotating the lower mold 2341 can allow the straight bar 2342 to move within the movable groove 2332. When the straight bar 2342 and the straight bar groove 2331 are not aligned, the lower mold 2341 cannot be removed from the lower plate 2334. The disassembly and assembly modes of the movable component 232 and the upper mold component 235 are the same as those of the lower mold 2341 and the lower plate 2334. Therefore, users can more easily disassemble and assemble the lower mold component 234 and the upper mold component 235.

[0029] The working principle of this utility model is explained below: Unless otherwise specified, all internal mechanical structures of the die-casting mechanism for the precision-aligned die-casting machine are fixed by threads. To allow for a more intuitive observation of the technical features, bolt connections are appropriately concealed in the figures. When using the precision-aligned die-casting mechanism, the user can install upper mold components 235 and lower mold components 234 of different shapes onto the movable plate 2321 and lower plate 2334. During installation, the user only needs to prepare and insert the insertion post 2343 and straight bar 2342 into the cylindrical groove 2333 and straight bar groove 2331, and then rotate the entire lower mold 2341. At this time, the straight bar 2342 moves within the movable groove 2332. Simply rotate the straight bar 2342 until it is no longer aligned with the straight bar groove 2331 to fix the lower mold 2341 onto the lower plate 2321. On 34, the upper mold assembly 235 is also installed on the movable plate 2321 in the same way. After the lower mold assembly 234 and the upper mold assembly 235 are installed, the user can start the driver 11 through the controller 13. The operation of the driver 11 can directly move the hydraulic cylinder 14 downward and move the movable assembly 232 on the column 231 for limited movement. At this time, the rotating ball 2322 rotates in the arc groove 21 for limited movement, so that the upper mold assembly 235 can accurately align with the lower mold assembly 234 for die casting. Through the cooperation of the above structures, the die casting mechanism for the die casting machine with precise alignment can meet the premise of precise die casting, and make it easier for the user to replace the lower mold assembly 234 and the upper mold assembly 235, thereby improving the applicability of the die casting mechanism for the die casting machine with precise alignment to various molds.

[0030] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
