Description

Technical Field

[0001] This invention relates to the technical field of die casting for new energy vehicle housings, and in particular to a die casting molding apparatus for new energy vehicle housings. Background Technology

[0002] With the rapid development of the new energy vehicle industry, high-strength and lightweight structural components (high-strength and high-toughness die-cast aluminum alloys and high-quality magnesium alloys) have become core components of the vehicle body and electric drive system. In addition, high-quality copper castings and titanium castings are increasingly widely used in thermal management systems, structural connectors and other fields. The above castings are usually formed by pressure casting process and have the characteristics of thin walls, complex ribs and integrated cooling channels. The surface quality and cleanliness requirements of the die-casting molds are extremely stringent. During the die casting process, residual mold release agent, high-temperature sintering products (carbon deposits) from molten aluminum, magnesium, copper, and titanium alloys on the mold surface, melt adhesion, and stubborn deposits such as tiny flash aluminum, copper, and titanium burrs will gradually accumulate on the mold cavity surface, especially on the fixed mold side. If not cleaned in time, this will lead to cold shuts, porosity, scratches, mold sticking, and even internal structural defects in the castings, seriously affecting the mechanical properties, airtightness (especially critical for motor housings and battery pack housings), and yield of the castings. At the same time, it will accelerate the generation of thermal fatigue cracks in the mold and significantly shorten the mold life.

[0003] Currently, the following problems exist in the mold cleaning of the aforementioned high-quality die-cast parts: 1. Operators use oilstones, sandpaper, copper shovels, or pneumatic tools to enter the mold after it is opened to grind or remove impurities. However, this method poses a serious safety hazard: the surface temperature of the mold is still as high as 100~200℃, which poses a risk of burns. 2. If the die-casting machine does not fully implement energy lock, it may cause accidental mold closing and serious extrusion accidents; 3. The metal dust generated during the cleaning process poses a risk of combustion and explosion, and can damage the respiratory system of operators; 4. The quality of manual cleaning is highly dependent on the operator's experience. It is difficult to thoroughly clean complex parts such as deep cavities, slender reinforcing ribs, and cooling water channels. It is also easy to cause scratches on the mold surface, blunting of edges and corners, or damage to the surface coating, leading to premature mold failure and failing to meet the precision requirements of high-strength and lightweight structural parts. 5. Some large die-casting companies use industrial robots or CNC machine tools equipped with cleaning tools (dry ice nozzles, laser heads, rotary files) for programmed trajectory cleaning. This type of equipment can be operated remotely, avoiding direct contact between personnel and high-temperature molds, but it has the following drawbacks: First, for molds of high-strength and tough structural components such as new energy vehicle shells, the cavities are complex and the surfaces are varied, resulting in a large workload and long cycle for offline programming and trajectory teaching. Moreover, the molds need to be reprogrammed after modification, which is not flexible enough. Second, the robot lacks real force feedback perception, making it difficult to judge the adhesion strength of carbon deposits or melting points, which can easily lead to incomplete cleaning or over-grinding, affecting the quality of castings. Third, the equipment is expensive and complex to maintain, which is not friendly to small and medium-sized enterprises. For high-quality copper and titanium casting molds, due to their higher die casting temperatures (copper alloys can reach over 1000℃, and titanium alloys even higher), the carbon deposits and melting on the mold surface are more severe, making programmatic cleaning less adaptable.

[0004] Therefore, there is an urgent need for a die-casting molding device for new energy vehicle shells to solve the above problems. Summary of the Invention

[0019] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

In the description of this invention, it should be understood that if terms such as "upper," "lower," "left," and "right" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, they are only for the convenience of describing this invention 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, the terms used to describe positional relationships in the drawings are only for illustrative purposes and should not be construed as limiting this invention. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0021] The implementation of the present invention will be described in detail below with reference to specific embodiments.

[0022] In this embodiment: Reference Figures 1-3 The diagram shows a preferred embodiment of the present invention.

[0023] This embodiment provides a die-casting molding apparatus for a new energy vehicle shell, comprising: The die-casting molding execution table 1 has a fixed mold base 12 and a movable mold base 14 to fix the die-casting mold 15 and perform the die-casting operation; A contouring operating table 11, on which a limiting model 16 with the same shape as the die-casting mold 15 is installed via a quick-change base 13; Processing component 2 is located on one side of the die-casting molding execution table 1 and is used to clean the die-casting mold 15 in a follow-up manner; The processing component 2 includes: The X-axis follower module 21 and the Y-axis follower module 22 are used to realize the synchronous transmission of motion in the horizontal direction; The follow-up operation component 23 includes a control component 237 and a tool component 238, wherein the control component 237 is for gripping and driving, and the tool component 238 is for mounting cleaning tools; The follow-up operation component 23 also includes two sets of corresponding follow-up assembly frames 231 driven by the Y-axis follow-up module 22, and a spatial degree of freedom transmission mechanism connected between the two follow-up assembly frames 231. The control component 237 and the tool component 238 are respectively connected to the two ends of the spatial degree of freedom transmission mechanism. The movement of the control component 237 is mechanically and synchronously transmitted to the tool component 238 through the X-axis follower module 21, the Y-axis follower module 22 and the spatial degree of freedom transmission mechanism, so that the tool component 238 performs synchronous actions with the control component 237, including at least horizontal movement, vertical extension and retraction and spatial swing, in order to clean the mold part fixed by the fixed mold base 12.

[0024] Specifically, the X-axis follower module 21 includes a linear guide rail and a rack laid along the X direction, and the Y-axis follower module 22 includes a linear guide rail and a rack laid along the Y direction. The two are arranged perpendicularly to each other and stacked to form a two-dimensional planar motion platform. The X-axis drive motor 221 and the Y-axis drive motor 2311 are both servo motors, which drive the corresponding gears to move along the rack to achieve precise positioning.

[0025] like Figure 4 As shown, the spatial degree-of-freedom transfer mechanism includes: Spherical joint structures respectively installed on the two sets of follower assembly frames 231; Two Z-axis follower shafts 233 are telescopically installed within the ball joint structure; The linkage assembly disposed between the ends of the two Z-axis follower shafts 233 is used to enable the two Z-axis follower shafts 233 to extend and retract synchronously and swing synchronously along the K direction. And a swaying clamping structure respectively disposed at the ends of the two Z-axis follower shafts 233, wherein the control component 237 and the tool component 238 are respectively fixed on the clamping structure.

[0026] Wherein, the K-axis oscillation refers to the oscillation around... Figure 1 The pitch motion along the K-axis, the spatial oscillation including rotational motion (J-direction) around the vertical axis and pitch motion (K-direction) around the horizontal axis, thereby simulating the multi-degree-of-freedom posture of human hand operation.

[0027] The spherical joint structure includes: a K-axis locking seat 2312 connected to the follower assembly frame 231 by a rotating shaft, and a spherical angle follower bushing 2331 locked in the K-axis locking seat 2312, wherein the Z-axis follower shaft 233 is inserted through and telescopically installed in the spherical angle follower bushing 2331; The spherical angle follower bushing 2331 is provided with a Z-axis drive motor 232, the surface of the Z-axis follower shaft 233 is provided with a tooth groove, and the output shaft of the Z-axis drive motor 232 is sleeved with a gear that meshes with the tooth groove. It is worth noting that the ends of the two Z-axis follower shafts 233 are also connected by an elastic belt 2333; the toothed grooves on the surface of the Z-axis follower shaft 233 are distributed in a ring shape on the surface of the Z-axis follower shaft 233 and have a certain length, so along the Z-axis follower shaft 233... Figure 1 The J-axis can rotate at a certain angle and transmit the rotation to one end of the tool assembly 238 via the elastic belt 2333, so as to simulate the multi-degree-of-freedom posture of human hand operation. A plurality of first magnetic switches 2313 are arranged in a ring on the K-direction mounting base 2312. The outer side of the spherical angle follower sleeve 2331 is fitted with a contact ring 2332 corresponding to the first magnetic switches 2313. When the spherical angle follower sleeve 2331 rotates relative to the K-direction mounting base 2312 to a preset angle, the contact ring 2332 couples with the first magnetic switch 2313 at the corresponding position to generate a trigger signal to control the Z-direction drive motor 232 to start, thereby realizing the electric assisted motion of the above-mentioned spatial degree of freedom. At the same time, the first magnetic switches 2313 are also used to limit the maximum swing range of the spherical angle follower sleeve 2331 to prevent overtravel.

[0028] The linkage component includes: A connecting sleeve 239 is coaxially mounted at the ends of two Z-axis follower shafts 233. A rocker arm 234 is connected to the two connecting sleeves 239 by a rotating shaft. An adjusting sleeve 235 is sleeved between the two rocker arms 234. A locking element is provided on the adjusting sleeve 235 for locking the extension length of the rocker arm 234. The clamp structure is an L-axis follower clamp 236, and the ends of the two Z-axis follower shafts 233 are provided with connectors 2334. The two L-axis follower clamps 236 are respectively rotatably connected to the two connectors 2334. Both sides of the rotating shaft connection portion of the two L-direction follower clamps 236 are provided with lifting rings 2361, and lifting cables 2362 are crisscrossed by the four lifting rings 2361, so that when one of the L-direction follower clamps 236 rotates, the other L-direction follower clamp 236 is driven to rotate synchronously and in the same direction through the crisscrossed lifting cables 2362.

[0029] The bottom of the adjusting sleeve 235 has two parallel sliding grooves 2351, and sliders 2352 are slidably installed through the two sliding grooves 2351 respectively. Both sliders 2352 are connected to a U-shaped winding rod 2353 on the opposite side. A guide ring 2354 is also provided on the side of the adjusting sleeve 235 near the contouring operating table 11. The two lifting cables 2362 cross and pass through the guide ring 2354 and are respectively limited in length by the corresponding winding rods 2353. The winding rods 2353 can slide along the slide groove 2351, thereby improving the smoothness of angle adjustment between the control component 237 and the tool component 238. When adjusting the distance between the control component 237 and the tool component 238, the length of the lifting cables 2362 can be adjusted by winding rods 2353 to maintain the tension of the two lifting cables 2362.

[0030] exist Figures 5-8In the control component 237, the grip rod 2376 includes an adjustment block 2371 installed inside the grip rod 2376. The adjustment block 2371 is threadedly connected to a telescopic ball rod 2372 that passes through both ends of the grip rod 2376. The grip rod 2376 also has an elastic element 2374 that acts on the adjustment block 2371 and an adjusting screw sleeve 2373 for adjusting the preload of the elastic element 2374. The telescopic ball bar 2372 is a bar with a ball embedded in the contact end. The ball abuts against the surface of the limiting model 16, which improves the smoothness of the control component 237 during the operation and avoids wear on the surface of the limiting model 16. The adjusting sleeve 2373 can adjust its screw depth in the gripping rod 2376 through the thread, thereby changing the amount of compression on one end of the elastic element 2374, thereby adjusting the squeezing elastic force of the ball end of the telescopic ball rod 2372, so that the operator can customize the grip feel and the magnitude of the return force according to the mold cleaning requirements. Meanwhile, the rotating telescopic ball bar 2372 can adjust the distance of the telescopic ball bar 2372 extending beyond the end of the grip bar 2376 through its threaded engagement with the adjusting block 2371, so as to adapt to the hand size of different operators and the surface contour of different limit models 16, thereby improving operating comfort and flexibility.

[0031] The ends of the telescopic ball bar 2372 and the grip bar 2376 are respectively equipped with corresponding second magnetic switches 2375. When the operator grips the telescopic ball bar 2372 and pushes it to a certain depth, the two second magnetic switches 2375 approach each other and trigger, generating a safety signal or a working signal to start the cleaning tool. This achieves convenient control by starting when gripped and stopping when released, giving the control component 237 a safety start / stop line to the tool component 238, thus preventing damage to the die-casting mold 15. Simultaneously, the second magnetic switch 2375 is also linked with the control circuit of the first magnetic switch 2313 and the Z-axis drive motor 232, ensuring that the electric auxiliary function can only be activated when the tool component 238 is within a safe posture range.

[0032] A protective glass 17 is installed between the contouring worktable 11 and the die-casting execution table 1; the tool assembly 238 is one of a dry ice spray nozzle, a copper shovel, or a rotating brush; the protective glass 17 is made of explosion-proof laminated glass, and its frame is provided with a sealing strip to prevent dry ice or metal splashes from causing injury to the operator during the cleaning process.

[0033] The X-axis follower module 21 is driven by an X-axis drive motor 221 mounted on the Y-axis follower module 22, and the Y-axis follower module 22 is driven by a Y-axis drive motor 2311 mounted on the follower assembly frame 231.

[0034] During use, according to the die-casting mold 15 to be cleaned, the corresponding limit model 16 is selected and installed on the contouring operating table 11 through the quick-change base 13; the operator stands in front of the contouring operating table 11, holds the telescopic ball bar 2372 of the control component 237, and presses it slightly to trigger the second magnetic switch 2375, and the system enters the standby state. The operator pushes the control component 237 to move along the X and Y directions (synchronously transmitted by the X-axis follower module 21 and the Y-axis follower module 22), and pushes and pulls to achieve Z-axis extension and retraction; by rotating the wrist, the operator achieves J-axis rotation and K-axis swing. These spatial posture changes are mechanically and synchronously transmitted to the tool component 238 through the ball joint structure, linkage component and cross lifting cable 2362, so that the tool component 238 replicates the exact same trajectory and angle on the fixed mold surface of the die-casting mold 15. When the tool assembly 238 comes into contact with carbon deposits or scale, the reaction force is directly fed back to the control assembly 237 through the mechanical transmission chain. The operator can sense the resistance and thus precisely control the cleaning force. If the operator accidentally pushes the tool assembly 238 into a dangerous area on the mold (bottom of the deep rib, edge of the venting groove), the limit model 16 will block the further movement of the control assembly 237 in advance. At the same time, the touch ring 2332 triggers the first magnetic switch 2313, which emits an audible and visual alarm and locks the movement direction of the Z-axis drive motor 232 to avoid collision. To balance ease of use and safety, a probe is usually configured for the tool component 238 and a real-time monitoring screen is configured for the control component 237, so that operators can have a visual perception in addition to sensing carbon deposits or scale points by reaction force resistance. During the cleaning process, the protective glass 17 completely isolates the die-casting area from the operating area to ensure safety. After releasing the control component 237, the elastic element 2374 automatically resets all moving parts, the second magnetic switch 2375 disconnects, and the cleaning tool stops working. The entire cleaning process does not require direct contact with the high-temperature mold or programming; it is entirely completed manually based on the tactile guidance of the limit model 16.

[0035] This solution achieves fully mechanical synchronous transmission between the control component 237 and the tool component 238 through the X-axis follower module 21, the Y-axis follower module 22, and the spatial degree-of-freedom transmission mechanism (spherical joint structure, linkage component, cross lifting cable 2362, etc.), eliminating the need for electronic sensors (except for auxiliary switches) and complex programming. When the operator pushes the control component 237, the tool component 238 replicates the exact same trajectory and posture on the mold surface; the resistance from carbon deposits or scale is directly transmitted in the reverse direction to the hand, providing realistic and timely force feedback. The operator can precisely control the cleaning force based on feel, avoiding incomplete cleaning or over-grinding.

[0036] During operation, the operator stands in front of the contouring worktable 11 and remotely drives the tool assembly 238 to clean the surface of the mold fixed to the mold base 12 via the control component 237. A protective glass 17 is installed between the mold and the die-casting execution table 1, completely preventing personnel from directly contacting the high-temperature mold, the moving parts of the high-pressure die-casting machine, and the metal dust generated during cleaning. At the same time, the second magnetic switch 2375 enables automatic start-up when gripped and automatic stop-up when released, eliminating accidental start-up and significantly improving production safety.

[0037] Furthermore, the contouring operating table 11 is equipped with a limiting model 16 (which relies on 3D printing technology and is inexpensive) that matches the shape of the die-casting mold 15, and its surface can be covered with a flexible buffer layer. When the operator accidentally pushes the tool assembly 238 towards a dangerous area on the mold (bottom of deep ribs, edge of venting grooves), the limiting model 16 will block the movement of the control assembly 237 in advance. At the same time, the touch ring 2332 is coupled with the first magnetic switch 2313, which will issue an audible and visual alarm and lock the movement direction of the Z-axis drive motor 232, effectively preventing the tool head from hitting the mold. This is especially suitable for molds with deep cavities and complex ribs, such as those for new energy vehicle housings, to avoid mold damage caused by misoperation.

[0038] The spatial degree-of-freedom transmission mechanism supports the Z-axis extension and retraction, K-axis swing, J-axis rotation of the Z-axis follower shaft 233 and the independent swing of the L-axis follower clamp 236. The synchronous and unidirectional transmission of the movement at both ends is achieved through the elastic belt 2333 and the cross lifting cable 2362, enabling the tool assembly 238 to simulate the multi-degree-of-freedom posture of the human hand, easily enter complex parts such as deep cavities, the side of the reinforcing ribs, and the inlet of the cooling water channel, ensuring that there are no dead angles in the cleaning.

[0039] The main transmission components use mature mechanical components such as gears and racks, universal joints, and cables. They do not require high-precision servo motors (Z-axis drive motor 232 is an optional auxiliary drive) or expensive robot control systems. They have low manufacturing costs, simple maintenance, and high reliability, making them suitable for long-term stable operation in the harsh environment of die-casting workshops.

[0040] This invention effectively solves the problems of high risk, unstable quality, and easy damage to the mold caused by manual operation in the cleaning of existing new energy vehicle die-casting molds 15 after use, as well as the problems of large workload, lack of force feedback, high cost, and poor adaptability of automated programming cleaning. It provides a safe, efficient, low-cost, and easy-to-operate remote mechanical follow-up cleaning solution for die-casting molds 15 of high-strength and tough lightweight structural parts (aluminum alloy, magnesium alloy) and high-quality copper and titanium castings.

[0041] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
