Description

Technical Field

[0001] The present invention relates to the technical field of automotive molds, and particularly to a die carrier for a large integrated aluminum die-cast structural part of a new energy vehicle. Background Art

[0002] New energy vehicles refer to vehicles that use unconventional vehicle fuels as the power source (or use conventional vehicle fuels and adopt new in-vehicle power devices), integrating advanced technologies in vehicle power control and drive, and forming vehicles with advanced technical principles, new technologies, and new structures. In order to ensure the overall body strength, the structural parts of new energy vehicles are usually processed by integral aluminum die-casting, and the die-cast structure has stronger tensile strength.

[0003] During the die-casting process, it is necessary to work through a mold. The mold is connected to external equipment through a die carrier. The die carrier is the support of the mold, which combines and fixes each part of the mold according to certain rules and positions, and the part that enables the mold to be installed on the die-casting machine for work is called the die carrier.

[0004] The traditional die carrier includes a fixed module and a moving module connected by a limiting component. The fixed module is connected to the cavity block of the mold, and the moving module is connected to the core block of the mold. The cavity block and the core block form a complete mold. Usually, a clamping groove is provided on the die carrier, and the mold and the clamping groove are usually clamped by interference fit. Although the interference fit is stable, it is not convenient for maintenance after long-term use, resulting in high later maintenance costs. In view of the above problems, a solution is proposed below. Summary of the Invention

[0005] The purpose of the present invention is to provide a die carrier for a large integrated aluminum die-cast structural part of a new energy vehicle, which solves the problems of difficult disassembly and inconvenient maintenance.

The triangular block is fixed to the side surface of the second crown gear, and the triangular block passes through the corresponding moving template or fixed template to correspond to the locking part. The first spring is fixed to one end of the triangular block for limiting.

[0014] Preferably, the locking part includes a rotating rod, a pressing block, a bracket, a receiving frame and an adjusting part. The bracket is fixedly installed on one side of the fixed template or the moving template close to the limiting part. The rotating rod is rotatably arranged inside the bracket.

The pressing block is fixed to one end of the rotating rod close to the triangular block. The receiving frame is installed on the corresponding fixed template or moving template of the bracket. The adjusting part is installed at one end of the rotating rod away from the pressing block. The adjusting part is mutually matched with the receiving frame.

[0015] Preferably, the adjusting part includes an outer sleeve, a pressing piece and a threaded rod. The outer sleeve is fixed to one end of the rotating rod. The outer sleeve is sleeved on the threaded rod. The threaded rod is in threaded cooperation with the outer sleeve. The pressing piece is sleeved and fixed on the threaded rod.

[0016] Preferably, the guiding part includes an inner rod, an outer tube, a ball and a second spring. The outer tube is fixed to the mounting surface of the fixed template.

[0020] Preferably, the number of the guiding parts is even and they are arranged symmetrically left and right.

[0021] Beneficial effects:

[0022] (1) The clamping groove is used to limit the mold body in the horizontal direction, and the wedge-shaped clamping block is used to limit the mold body in the vertical direction, so as to install the mold body, ensure normal use, and at the same time facilitate disassembly, maintenance, and cost reduction;

[0023] (2) The threaded fit between the lead screw and the wedge-shaped clamping block is used to adjust and fix the clamping block between the wedge-shaped clamping blocks, avoiding the movement of the wedge-shaped clamping block caused by the self-gravity of the mold body and ensuring safety;

[0024] (3) The clamping part uses two lead screws with opposite helix directions to be connected through a coupling, ensuring the symmetry and synchronism during the adjustment of the wedge-shaped clamping block, thus ensuring the stability of the mold body and at the same time ensuring the high efficiency of adjustment, making it more convenient to use;

[0025] (4) The guiding part uses the insertion fit between the inner rod and the outer tube to achieve a positioning effect, and the balls arranged on the outer surface of the inner rod can ensure that the friction is reduced when the inner rod moves inside the outer tube. At the same time, the setting of the second spring can retract the balls, facilitating the insertion of the inner rod into the outer tube;

[0026] (5) The locking part uses the rotating rod to drive the cooperation of the adjusting part and the bearing bracket, and plays a fixing role through the pressure and friction between the pressing piece and the bearing bracket, so as to fix the mold body between the moving template and the fixed template, avoiding it from falling apart when not in use and ensuring correspondence and safety;

[0027] (6) The limiting part uses the cooperation between the first spring, the first crown gear and the second crown gear to limit the lead screw, avoiding the random rotation of the lead screw when subjected to external forces;

[0028] (7) The limiting part and the locking part cooperate. Only when the locking part is in the closed state, the limitation of the limiting part will be cancelled, and then the operation of maintaining the mold body can be carried out, avoiding the mold body from being replaced externally during operation and ensuring safety.

Detailed implementation manners

[0038] The following is only the preferred implementation manner of the present invention, and the protection scope is not limited to this embodiment. Any technical solutions falling within the idea of the present invention shall belong to the protection scope of the present invention. At the same time, it should be pointed out that for those of ordinary skill in the art, several improvements and refinements made without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.

[0039] See Figure 1 As shown, a die carrier for a large integrated aluminum die-casting new energy vehicle structural part includes a moving template and a fixed template, and further includes a guiding part, a clamping part, a locking part, a limiting part and a mold body;

[0040] See Figure 1 , Figure 7 and Figure 8As shown, the fixed template 2 and the moving template 1 are symmetrically arranged up and down. The opposite surfaces of the fixed template 2 and the moving template 1 are mounting surfaces 8. The guiding part 3 includes an inner rod 29, an outer tube 30, a ball 31 and a second spring 32. The outer tube 30 is fixed on the mounting surface 8 of the fixed template 2, and the inner rod 29 is fixed on the mounting surface 8 of the moving template 1. The inner rod 29 and the outer tube 30 correspond to and fit with each other. A plurality of notches 33 are evenly formed on the outer side surface of the inner rod 29 near one end of the outer tube 30. The second spring 32 is installed inside the notches 33. The ball 31 is rotatably arranged in the notches 33, and the second spring 32 is located between the notches 33 and the ball 31.

[0041] The guiding part 3 uses the insertion and cooperation of the inner rod 29 and the outer tube 30 to achieve a positioning effect. The balls 31 arranged on the outer surface of the inner rod 29 can ensure that the friction is reduced when the inner rod 29 moves inside the outer tube 30. At the same time, the setting of the second spring 32 can retract the balls 31, facilitating the insertion of the inner rod 29 into the outer tube 30.

[0042] See Figure 2 and Figure 3 As shown, clamping grooves 9 are formed on both of the two mounting surfaces 8. A clamping plate 10 that fits with each other is arranged inside the clamping grooves 9. The edge of the clamping plate 10 close to the clamping part 4 is beveled. The inclined surface can increase the contact area and ensure stability. The two clamping plates 10 are respectively fixedly connected to the core block and the cavity block of the mold body 7. The clamping part 4 includes a lead screw 11, a wedge-shaped clamping block 12 and a coupling 13. Sliding grooves 14 communicating with the clamping grooves 9 are symmetrically formed on the mounting surface 8. The wedge-shaped clamping block 12 is slidably arranged inside the sliding grooves 14. There are two lead screws 11, and the two lead screws 11 have opposite thread directions. The two lead screws 11 are rotatably arranged on one side of the clamping groove 9. The lead screws 11 correspond to the sliding grooves 14. An arc-shaped plate 34 is in threaded cooperation with the lead screw 11. The arc-shaped plate 34 is fixedly connected to the wedge-shaped clamping block 12. The coupling 13 is used to connect the two lead screws 11. A hexagonal groove 35 for convenient screwing is formed at one end of the lead screw 11 away from the coupling 13. The clamping groove 9 is used to limit the mold body 7 in the horizontal direction, and the wedge-shaped clamping block 12 is used to limit the mold body 7 in the vertical direction, so as to install the mold body 7, ensure normal use, and at the same time facilitate disassembly, convenient maintenance and cost reduction.

[0043] The threaded cooperation between the lead screw 11 and the wedge-shaped clamping block 12 is used to adjust and fix the clamping block between the wedge-shaped clamping blocks 12, avoiding the movement of the wedge-shaped clamping block 12 caused by the self-weight of the mold body 7 and ensuring safety. The clamping part 4 uses two lead screws 11 with opposite thread directions to be connected through a coupling 13, ensuring the symmetry and synchronism during the adjustment of the wedge-shaped clamping block 12, thus ensuring the stability of the mold body 7 and at the same time ensuring the high efficiency of adjustment and more convenient use.

[0044] See Figure 4 and Figure 5As shown, the limiting part 6 includes a first spring 15, a first crown gear 17, a second crown gear 18, a triangular block 19 and a connecting rod 20. The connecting rod 20 is fixed to one end of the lead screw 11. The first crown gear 17 is fixed to the connecting rod 20. The second crown gear 18 is located between the lead screw 11 and the first crown gear 17. The second crown gear 18 is slidably arranged on the connecting rod 20. The first crown gear 17 and the second crown gear 18 mesh with each other. The triangular block 19 is fixed to the side of the second crown gear 18, and the triangular block 19 passes through the corresponding moving template 1 or fixed template 2 to correspond to the locking part 5. The first spring 15 is fixed to one end of the triangular block 19 for limiting. The limiting part 6 uses the cooperation between the spring and the first crown gear 17 and the second crown gear 18 to limit the lead screw 11 and prevent the lead screw 11 from rotating randomly when subjected to external forces.

[0045] See Figure 4 As shown, the locking part 5 includes a rotating rod 21, a pressing block 23, a bracket 22, a receiving bracket 24, and an adjusting part 25. The bracket 22 is fixedly installed on one side of the fixed template 2 or the moving template 1 close to the triangular block 19. The rotating rod 21 is rotatably arranged inside the bracket 22. The connection line between the rotation center of the rotating rod 21 and the triangular block 19 is in the vertical direction. The pressing block 23 is fixed to one end of the rotating rod 21 close to the triangular block 19. The receiving bracket 24 is installed on the corresponding fixed template 2 or moving template 1 of the bracket 22. The adjusting part 25 is installed at one end of the rotating rod 21. The adjusting part 25 and the receiving bracket 24 cooperate with each other.

[0046] See Figure 6 As shown, the adjusting part 25 includes an outer sleeve 26, a pressing piece 27 and a threaded rod 28. The outer sleeve 26 is fixed to one end of the rotating rod 21. The outer sleeve 26 is sleeved on the threaded rod 28. The threaded rod 28 is in threaded cooperation with the outer sleeve 26. The pressing piece 27 is sleeved and fixed on the threaded rod 28.

[0047] The locking part 5 uses the rotating rod 21 to drive the adjusting part 25 and the receiving bracket 24 to cooperate, and plays a fixing role through the pressure and friction between the pressing piece 27 and the receiving bracket 24, so as to fix the mold body 7 between the moving template 1 and the fixed template 2, prevent it from spreading when not in use, and ensure correspondence and safety.

[0048] The limiting part 6 and the locking part 5 cooperate. Only when the locking part 5 is in the closed working state, will the limitation of the limiting part 6 be cancelled, and then the operation of maintaining the mold body 7 can be carried out, preventing the mold body 7 from being externally replaced during work and ensuring safety.

[0049] Working principle: During operation, the mold body 7 is installed on the equipment through the fixed template 2 and the movable template 1. When maintenance of the mold body 7 is required, rotate the rotating rod 21. The rotating rod 21 will drive the outer sleeve 26 to rotate, thereby driving the threaded rod 28 and the pressing piece 27 to rotate. Through the thread fit between the threaded rod 28 and the outer sleeve 26, rotating the threaded rod 28 drives the pressing piece 27 to move relatively along the axial direction of the threaded rod 28. The fixation between the fixed template 2 and the movable template 1 is ensured by the pressure and friction between the pressing piece 27 and the receiving frame 24. At the same time, the rotation of the rotating rod 21 will drive the pressing block 23 to rotate. During the rotation of the pressing block 23, it will act on the inclined surface of the triangular block 19, thereby pushing the triangular block 19 to move. The triangular block 19 will drive the connecting rod 20 to move. The movement of the connecting rod 20 drives the separation of the first crown gear 17 and the second crown gear 18, thereby removing the limit on the lead screw 11. Rotate the lead screw 11 through the hexagonal groove. The two lead screws 11 rotate synchronously through the coupling 13. Since the helix directions of the two lead screws 11 are opposite, it drives the arc-shaped plate 34 to move in two opposite directions, thereby driving the wedge-shaped clamping blocks 12 to move in opposite directions, that is, removing the restriction on the clamping plate 10, facilitating the removal of the mold body 7 for maintenance.
