Description

Technical Field

[0001] The present invention relates to the technical field of die-casting molds, and specifically to an integrated die-casting mold for the timing cover of new energy vehicles. Background Art

[0002] The automotive timing cover is a component fixed to the side of the engine and connected to the cylinder block, used to protect the timing gears and chains. It provides a strong dust-proof barrier, effectively resisting external dust and debris, and protecting the internal precision components from wear. At the same time, it can also ensure the sealing of the camshaft drive mechanism, prevent lubricating oil leakage, and avoid the pollution of the engine interior and the damage of the lubrication system.

[0003] Chinese Patent CN215614961U discloses a positioning device for the die-casting mold ejector mechanism, including an ejector mechanism connected to the core-pulling. The tail end of the ejector mechanism passes through the guide block and is connected to a push plate through a connecting rod. A positioning rod is vertically inserted on the forming part of the ejector mechanism, the top end of the positioning rod is connected to an oil cylinder, a positioning groove is provided on the ejector mechanism, and a protrusion matching the positioning groove is provided at the bottom end of the positioning rod. During the production process of the timing cover, it ensures that the ejector mechanism reaches the specified position, so that there is no flash and excess material in the fuel filler hole of the timing cover.

[0004] Although the above technical solution already has the ability to adjust the position of the ejector mechanism to ensure the precise forming of the timing cover during die-casting. However, in the actual operation of the die-casting mold, the ejector mechanism shapes the holes of the casting through the ejector rod. In this process, the ejector rod needs to move obliquely and telescopically in the die-casting mold. Over time, due to frequent and continuous frictional contact between the ejector rod and the die-casting mold body, wear gradually occurs, and then a certain gap is formed. This gap becomes a potential channel for the casting liquid to penetrate during the casting process, resulting in excessive burrs on the surface of the casting, seriously affecting the final quality of the product. To solve this problem, traditional methods often require replacing the damaged ejector rod. However, the replacement process of the ejector rod is extremely cumbersome, not only involving the disassembly and reassembly of the mold, but also potentially damaging the overall structure of the mold, thus significantly reducing the production efficiency.

Detailed implementation mode

[0028] To further understand the features, technical means, specific purposes and functions achieved by the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation modes.

[0029] See Figures 1 to 10 As shown, the integral die-casting mold for the timing cover of a new energy vehicle includes a fixed template 2, a fixed die core 21 is installed on the fixed template 2, a mounting hole 22 is provided on the side of the fixed die core 21, and further includes a moving template 1, a moving die core 11 is installed on the moving template 1, the moving die core 11 and the fixed die core 21 are matched, a quick-release angled lifter mechanism 3 is installed between the moving die core 11 and the fixed die core 21, an angled lifter rod 31 extending into the interior of the mounting hole 22 is installed on the quick-release angled lifter mechanism 3, the quick-release angled lifter mechanism 3 is detachably connected to the angled lifter rod 31, and the connection part of the angled lifter rod 31 is arranged outside the quick-release angled lifter mechanism 3.

[0030] During the operation of the mold, the moving template 1 drives the moving die core 11 to move towards the fixed die core 21 until the two are closely attached to form a casting cavity required for casting. At this time, the quick-release angled lifter mechanism 3 installed between the moving die core 11 and the fixed die core 21 starts to play a role. An angled lifter rod 31 is installed on the quick-release angled lifter mechanism 3, and through the push of the quick-release angled lifter mechanism 3, the angled lifter rod 31 can enter the interior of the moving die core 11 from the mounting hole 22, ensuring the formation of a stable and precise casting cavity between the fixed die core 21 and the moving die core 11.

[0031] During the liquid injection stage, the casting liquid is conveyed into the interiors of the fixed mold core 21 and the movable mold core 11 through the liquid injection equipment, filling the entire casting cavity and finally solidifying to form the timing cover 5 with the inclined through hole 51. The design of the inclined through hole 51 meets the structural requirements of the timing cover 5 for new energy vehicles.

[0032] After casting is completed, the movable template 1 drives the movable mold core 11 to reset. At the same time, the quick-release angled lifter mechanism 3 also drives the angled lifter rod 31 to withdraw from the injection-molded timing cover 5, so as to smoothly remove the timing cover 5 from the fixed mold core 21.

[0033] During long-term use, if a large gap forms between the angled lifter rod 31 and the mounting hole 22 due to wear, resulting in excessive burrs on the surface of the casting, the detachable connection characteristic between the quick-release angled lifter mechanism 3 and the angled lifter rod 31 can be utilized at this time to quickly replace the angled lifter rod 31. Since the connection part of the angled lifter rod 31 is arranged outside the quick-release angled lifter mechanism 3, maintenance personnel can easily complete the replacement work of the angled lifter rod 31 without disassembling too many mold components, thus effectively solving the problem of excessive burrs on the casting and greatly improving the production efficiency and production quality.

[0034] See Figure 2 and Figure 3 As shown, the quick-release angled lifter mechanism 3 includes a pushing and moving mechanism 33 installed on the side of the fixed mold core 21. The movable end of the pushing and moving mechanism 33 is connected to the angled lifter rod 31. The quick-release angled lifter mechanism 3 also includes a stable pressing mechanism 34 installed on the side of the movable mold core 11, and the stable pressing mechanism 34 is used to drive the pushing and moving mechanism 33 to move.

[0035] During the mold clamping stage of the mold, the movable mold core 11 is driven by the movable template 1 to move towards the fixed mold core 21 until they are closely fitted to form the required casting cavity. At this time, the stable pressing mechanism 34 on the side of the movable mold core 11 also moves closer to the pushing and moving mechanism 33. When the stable pressing mechanism 34 collides with the pushing and moving mechanism 33, the stable pressing mechanism 34 begins to apply pressure to the pushing and moving mechanism 33, pushing it to move along the preset path.

[0036] The movement of the pushing and moving mechanism 33 drives the angled lifter rod 31 connected to its movable end, and the angled lifter rod 31 then extends into the interior of the movable mold core 11 along the mounting hole 22. This action ensures the formation of a stable and precise casting cavity between the fixed mold core 21 and the movable mold core 11, providing a basis for the subsequent casting process.

[0037] After the casting liquid is filled and solidified to form the timing cover 5, the mold enters the mold opening stage. At this time, the movable mold core 11 drives the stable pressure mechanism 34 to reset, and the stable pressure mechanism 34 is out of the state of conflict with the push-moving mechanism 33. Due to the connection between the push-moving mechanism 33 and the inclined ejector rod 31, the push-moving mechanism 33 is also reset, and at the same time drives the inclined ejector rod 31 to withdraw from the injection-molded timing cover 5 along the mounting hole 22.

[0038] The quick-release lift mechanism 3 realizes the effective movement of the lift rod 31 during the mold closing and opening process through the interaction between the stable pressure mechanism 34 and the push movement mechanism 33, thereby ensuring the accurate forming and smooth demoulding of the casting.

[0039] See also Figures 2 to 6 As shown, the pushing and moving mechanism 33 includes a sliding mounting frame 331 installed on the side of the fixed mold core 21, a first spring 333 is installed between the sliding mounting frame 331 and the fixed mold core 21, a sliding mounting groove 332 is provided on the sliding mounting frame 331, a diagonal rod mounting block 334 is slidably installed on the sliding mounting groove 332, and an inclined surface 3311 is also provided on the outer side of the sliding mounting frame 331 for contacting the stable pressure mechanism 34.

[0040] The sliding mounting frame 331 is slidably mounted on the side of the fixed mold core 21 and connected to the fixed mold core 21 through a specific sliding connection structure, allowing it to slide within a certain range. The first spring 333 is arranged between the sliding mounting frame 331 and the fixed mold core 21 to apply a thrust extending outward to the sliding mounting frame 331.

[0041] The sliding installation groove 332 provides a stable sliding path for the inclined rod installation block 334. The inclined rod installation block 334 is then slidably installed along this path and is used to fix the inclined ejector rod 31.

[0042] In the mold closing stage, as the movable mold core 11 gradually approaches and finally fits tightly with the fixed mold core 21, the stable pressure mechanism 34 also moves and conflicts with the inclined surface 3311 of the sliding mounting frame 331. This conflicting effect causes the sliding mounting frame 331 to be subjected to an inward force, thereby overcoming the thrust of the first spring 333 and shrinking and moving.

[0043] As the sliding mounting frame 331 shrinks and moves, during this process, the inclined rod mounting block 334 pushes the inclined ejector rod 31 to extend along the mounting hole 22 of the fixed mold core 21 toward the inside of the movable mold core 11. Since the inclined rod mounting block 334 and the mounting hole 22 are both inclined, the inclined rod mounting block 334 will make corresponding sliding adjustments in the sliding mounting groove 332 to ensure that the inclined ejector rod 31 can stably and accurately reach the predetermined position, thereby realizing the stable and accurate formation of the casting cavity between the fixed mold core 21 and the movable mold core 11.

[0044] See alsoFigure 4 and Figure 5 As shown in Figure 5 , the diagonal rod mounting block 334 is provided with an insertion hole 336. The insertion hole 336 is coaxially arranged with the mounting hole 22. A top-receding mechanism 337 is arranged inside the insertion hole 336. The diagonal rod mounting block 334 is provided with a plurality of limiting mounting grooves 335. The limiting mounting grooves 335 are evenly distributed around the insertion hole 336 as the axis. A limiting clamping mechanism 338 is also mounted on the limiting mounting grooves 335.

[0045] The diagonal rod mounting block 334 is designed with an insertion hole 336 coaxially arranged with the die mounting hole 22. The insertion hole 336 provides an accurate insertion path and mounting position for the diagonal ejector rod 31. A top-receding mechanism 337 is equipped inside the insertion hole 336. This mechanism can be compressed when the diagonal ejector rod 31 is installed, providing the necessary pre-tightening force for the diagonal ejector rod 31. And when the diagonal ejector rod 31 needs to be replaced, it will push out the diagonal ejector rod 31 through its elastic restoring force, facilitating disassembly.

[0046] In addition, the diagonal rod mounting block 334 is provided with a plurality of limiting mounting grooves 335 evenly distributed around the insertion hole 336 as the axis. The limiting mounting grooves 335 provide a mounting basis for the limiting clamping mechanism 338. After the diagonal ejector rod 31 is installed in place, the limiting clamping mechanism 338 can clamp and position the diagonal ejector rod 31, preventing it from displacing or falling off during the working process, and ensuring the casting accuracy and stability of the die.

[0047] When the diagonal ejector rod 31 needs to be replaced, the staff first unlocks the limiting clamping mechanism 338 to release the constraint on the diagonal ejector rod 31. Subsequently, the diagonal ejector rod 31 is pushed out of the insertion hole 336 under the action of the elastic restoring force of the top-receding mechanism 337, and the staff can easily extract and disassemble the diagonal ejector rod 31. After the disassembly of the old diagonal ejector rod 31 is completed, the staff presses the new diagonal ejector rod 31 back into the insertion hole 336 until the limiting clamping mechanism 338 clamps and positions the new diagonal ejector rod 31 again, thus completing the replacement process of the diagonal ejector rod 31. This process does not require disassembling too many die components, significantly improving the maintenance efficiency and production quality.

[0048] See Figures 5 to 8 As shown in Figures 5 to 8 , the top-receding mechanism 337 includes a sliding contact sleeve ring 3371 slidably mounted inside the insertion hole 336. A second spring 3372 is mounted between the sliding contact sleeve ring 3371 and the diagonal rod mounting block 334.

[0049] A second spring 3372 is assembled between the sliding contact collar 3371 and the inclined rod mounting block 334. During the installation of the lifter rod 31, the lifter rod 31 will push the sliding contact collar 3371, causing it to move axially along the insertion hole 336 and compress the second spring 3372, thereby forming a certain pre-tightening force. When it is necessary to remove the lifter rod 31, first, the unlocking limit clamping mechanism 338 is used to release the restraint on the lifter rod 31. Subsequently, the second spring 3372 releases the compression force using the stored elastic potential energy, pushing the sliding contact collar 3371 and the lifter rod 31 in contact therewith to move in the opposite direction, thereby elastically ejecting the lifter rod 31 out of the insertion hole 336. This process not only improves the convenience of disassembly but also ensures the stability and accuracy of the lifter rod 31 during replacement.

[0050] See Figures 5 to 7 As shown, the limit clamping mechanism 338 includes a plurality of limit blocks 3383 distributed in the limit mounting groove 335. A contact post 3384 is provided on the limit block 3383. The limit clamping mechanism 338 further includes a driving disk 3381 mounted on the inclined rod mounting block 334. A plurality of driving inclined grooves 3382 are provided on the driving disk 3381. The driving inclined grooves 3382 are in contact with the contact posts 3384. A third spring is installed between the driving disk 3381 and the inclined rod mounting block 334.

[0051] The limit clamping mechanism 338 is mainly composed of a plurality of limit blocks 3383 distributed in the limit mounting groove 335. A contact post 3384 is provided on each limit block 3383. In addition, the limit clamping mechanism 338 further includes a driving disk 3381 mounted on the inclined rod mounting block 334. The driving disk 3381 is provided with a plurality of driving inclined grooves 3382 corresponding to the number of contact posts 3384. A third spring is assembled between the driving disk 3381 and the inclined rod mounting block 334 to provide a reset driving force.

[0052] During the installation of the lifter rod 31, the operator first rotates the driving disk 3381. The rotation of the driving disk 3381 will compress the third spring and, at the same time, through the interaction between the driving inclined groove 3382 and the contact post 3384, push a plurality of contact posts 3384 to move synchronously. The movement of the contact posts 3384 then drives the limit blocks 3383 to expand and move along the path of the driving inclined groove 3382, thereby opening the insertion hole 336 to provide space for the insertion of the lifter rod 31.

[0053] When the ejector pin 31 is successfully inserted into the designated position of the insertion hole 336, the staff stops rotating the drive disk 3381. At this time, the third spring releases the compression force by using the elastic potential energy it stores, and pushes the drive disk 3381 to reset. During the reset process of the drive disk 3381, the limit catch 3383 moves towards the center of the insertion hole 336 under the guidance of the drive chute 3382, and finally tightly clamps the ejector pin 31 in the insertion hole 336, achieving the stable fixation of the ejector pin 31 at the designated position.

[0054] See Figures 2 to 4 As shown, the stable pressure application mechanism 34 includes a mounting bracket 341 installed on the moving die core 11. A telescopic frame 343 is installed on the mounting bracket 341. A fourth spring 342 is installed between the telescopic frame 343 and the mounting bracket 341. A push and press contact wheel 344 is installed on the telescopic frame 343.

[0055] During the mold closing stage of the mold, as the moving die core 11 moves towards the fixed die core 21 under the action of the driving force, the mounting bracket 341, as the main part of the stable pressure application mechanism 34, also moves towards the fixed die core 21. During this process, the telescopic frame 343 and the push and press contact wheel 344 on the mounting bracket 341 gradually approach the inclined surface 3311 of the sliding mounting frame 331 on the side of the fixed die core 21.

[0056] When the push and press contact wheel 344 comes into contact with the inclined surface 3311 of the sliding mounting frame 331, due to the continuous pressure during the mold closing process of the mold, the push and press contact wheel 344 will push and press the sliding mounting frame 331 inward along the inclined surface 3311. This pushing action causes the sliding mounting frame 331 to overcome the thrust of the first spring 333 and move in a contracting manner along the preset path. At the same time, the fourth spring 342 plays a buffering and adaptive role during the contact between the push and press contact wheel 344 and the inclined surface 3311, ensuring that the push and press contact wheel 344 can apply pressure smoothly and continuously, and avoiding impact or damage to the mold.

[0057] As the sliding mounting frame 331 moves in a contracting manner, the diagonal rod mounting block 334 connected to it also slides and adjusts along the sliding mounting groove 332, thereby pushing the ejector pin 31 to extend towards the inside of the moving die core 11 along the mounting hole 22 of the fixed die core 21. This action ensures the formation of a stable and precise casting cavity between the fixed die core 21 and the moving die core 11, providing a reliable guarantee for the subsequent casting process.

[0058] See Figures 4 to 10 As shown, a docking catch 311 is provided at the top of the ejector pin 31, and a positioning card slot 312 is provided on the docking catch 311.

[0059] First, the inclined ejector rod 31 is connected to the insertion hole 336 on the inclined rod mounting block 334 through the docking block 311 at its top. The positioning slot 312 provided on the docking block 311 not only serves for snap - fixing but also facilitates the use of installation tools by the staff for precise positioning and installation during the installation process. When the inclined ejector rod 31 is pressed into the insertion hole 336, the docking block 311 is clamped between the top - retreat mechanism 337 and the limit clamping mechanism 338, forming a stable connection structure.

[0060] See Figure 9 and Figure 10 As shown in

[0061] An auxiliary positioning hole 339 is also provided on the outer side of the inclined rod mounting block 334.

[0062] Dock the new inclined ejector rod 31 with the limit clamping head 44 on the push - press handle 43. By clamping the limit clamping head 44 onto the positioning slot 312 of the docking block 311, it is ensured that the inclined ejector rod 31 remains stable during the installation process and avoids skewing. Dock the positioning post 42 on the sliding guide rail 41 with the auxiliary positioning hole 339 of the inclined rod mounting block 334. This step ensures that the inclined ejector rod 31 to be installed is on the same axis as the insertion hole 336, improving the accuracy and efficiency of installation. Unlock the limit clamping mechanism 338 so that the inclined ejector rod 31 can move freely under the action of the push - press handle 43. The operator applies a thrust through the push - press handle 43 to smoothly and accurately push the inclined ejector rod 31 into the insertion hole 336. The guidance of the push - press handle 43 by the sliding guide rail 41 ensures the stability and accuracy of the inclined ejector rod 31 during the installation process.

[0063] See Figure 4 As shown in

[0064] Driven by the quick - release inclined ejector mechanism 3, the inclined ejector rod 31 slides along the inner wall of the wear - resistant guide sleeve 32. The wear - resistant guide sleeve 32 provides an accurate guiding function, ensuring that the inclined ejector rod 31 can accurately enter the moving die core 11, thereby forming a stable and precise casting cavity. Since the wear resistance of the wear - resistant guide sleeve 32 is higher than that of the inclined ejector rod 31, it can effectively withstand the friction and wear generated by the inclined ejector rod 31 during movement. Protect the fixed die core 21 from potential damage caused by the wear of the inclined ejector rod 31, thereby ensuring the overall stability of the mold and the quality of the casting.

[0065] Specific working principle: During the operation of the mold, the moving template 1 drives the moving die core 11 to move towards the fixed die core 21 until they are closely fitted to form a casting cavity required for casting. At this time, the quick-release angled lifter mechanism 3 installed between the moving die core 11 and the fixed die core 21 starts to function. The quick-release angled lifter mechanism 3 is equipped with an angled lifter rod 31. Driven by the quick-release angled lifter mechanism 3, the angled lifter rod 31 can enter the interior of the moving die core 11 from the mounting hole 22 to ensure the formation of a stable and precise casting cavity between the fixed die core 21 and the moving die core 11.

[0066] In the liquid injection stage, the casting liquid is transported to the interiors of the fixed die core 21 and the moving die core 11 through the liquid injection equipment, filling the entire casting cavity and finally solidifying to form a timing cover 5 with an inclined through hole 51. The design of the inclined through hole 51 meets the structural requirements of the timing cover 5 of new energy vehicles.

[0067] After casting is completed, the moving template 1 drives the moving die core 11 to reset. At the same time, the quick-release angled lifter mechanism 3 also drives the angled lifter rod 31 to withdraw from the injection-molded timing cover 5 so as to smoothly remove the timing cover 5 from the fixed die core 21.

[0068] During long-term use, if a large gap is formed between the angled lifter rod 31 and the mounting hole 22 due to wear, resulting in excessive burrs on the surface of the casting, the detachable connection characteristic between the quick-release angled lifter mechanism 3 and the angled lifter rod 31 can be utilized at this time to quickly replace the angled lifter rod 31. Since the connection part of the angled lifter rod 31 is arranged outside the quick-release angled lifter mechanism 3, maintenance personnel can easily complete the replacement work of the angled lifter rod 31 without disassembling too many mold components, thus effectively solving the problem of excessive burrs on the casting and greatly improving the production efficiency and production quality.

[0069] The above embodiments only represent one or several implementation manners of the present invention, and their descriptions are relatively specific and detailed, but should not be construed as a limitation on the protection scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
