[0003] When replacing traditional molds, workers mainly rely on cranes to lift the molds, then manually align the molds with the installation positions of the device, and then secure them by tightening a large number of bolts. Since molds are usually large and heavy, the lifting process is extremely difficult to accurately control, making it difficult to quickly and accurately place the molds in the appropriate position on the device, and often requires multiple adjustments. This not only consumes a lot of time, but also requires extremely high physical strength and operating skills from workers, and is extremely labor-intensive. At the same time, the long mold change process seriously reduces the effective working time of the equipment, increases production costs, and the uncertainty of manual operation can easily lead to mold installation deviations, which in turn affects the production quality of automotive parts.

DETAILED DESCRIPTION

[0032] To facilitate understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings. Several embodiments of the present invention are given in the drawings, but the present invention can be implemented in different forms and is not limited to the embodiments described in the text. On the contrary, these embodiments are provided to make the content disclosed in the present invention more thorough and comprehensive.

[0033] It should be noted that when an element is referred to as being "fixed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used in this article are for illustrative purposes only.

[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly connected by technicians in the technical field to which the present invention belongs. The terminology used in the specification of the present invention is for the purpose of describing specific embodiments and is not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0035] The embodiment of the present application provides a rapid mold changing device for automobile parts manufacturing molds. The schematic diagram of the rapid mold changing device for automobile parts manufacturing molds is as follows: Figure 1-4 The rapid die-changing device for automobile parts manufacturing dies comprises a processing table 10, the upper surface of the processing table 10 is connected to a support frame 20, the top of the support frame 20 is connected to an upper die mechanism 30, the bottom end of the upper die mechanism 30 is provided with a lower die mechanism 40, and the lower die mechanism 40 is connected to the upper surface of the processing table 10;

[0036] The lower mold mechanism 40 includes a fork-arm lift 41 connected to the inside of the processing table 10, a support plate 44 connected to the upper surface of the fork-arm lift 41, and a lower mold 42 connected to the upper surface of the support plate 44. The bottom end of the fork-arm lift 41 is connected to a translation assembly 43;

[0037] The translation assembly 43 includes a screw rod 431 rotatably connected to the bottom end of the processing table 10 , and a sliding plate 432 connected to the outer surface of the screw rod 431 through a nut, and the sliding plate 432 is connected to the bottom ends of the fork arm lift 41 .

[0038] It should be noted that, in this embodiment, the entire device constructs a complete mold installation and replacement system. The processing table 10 serves as a basic support structure to carry other components. The support frame 20 provides an installation position for the upper mold mechanism 30 and ensures its stability. In the lower mold mechanism 40, the fork-arm lift 41 can realize lifting and lowering actions through its own mechanical structure, which is used to adjust the height of the lower mold 42. In the translation assembly 43, the subsequent claims of the motor mention that it drives the screw rod 431 to rotate, and the screw rod 431 and the sliding plate 432 cooperate with the nut to convert the rotational motion of the screw rod into the linear motion of the sliding plate 432, thereby driving the fork-arm lift 41 and the lower mold 42 to translate.

[0039] The above structural design enables the lower mold 42 to be flexibly adjusted in height and translated, making it convenient to move the mold out of or into the processing table 10, greatly improving the convenience of mold changing, reducing dependence on large lifting equipment during mold changing, and reducing operational difficulty and safety risks.

[0040] Optional, please refer to the attached Figure 1 The support frame 20 includes columns 21 connected to multiple corners of the upper surface of the processing table 10, and a top plate 22 connected to the upper surfaces of the multiple columns 21. The upper mold mechanism 30 includes a cylinder 31 connected to the upper surface of the top plate 22. The output end of the cylinder 31 is connected to a lifting plate 32, and the bottom end of the lifting plate 32 is connected to an upper mold 33.

[0041] In this embodiment, the columns 21 and the top plate 22 of the support frame 20 form a stable frame structure, providing a reliable installation foundation for the upper mold mechanism 30. When the cylinder 31 is working, the compressed air is used to push the piston, so that the output end produces a linear displacement, driving the lifting plate 32 to move up and down, thereby realizing the lifting action of the upper mold 33. The structure is simple and efficient, and can accurately control the lifting height of the upper mold 33 to meet different production process requirements. At the same time, the stable support frame structure ensures the stability of the upper mold mechanism during the working process, improves the accuracy of mold clamping, and is conducive to improving product quality.

[0042] Optional, please refer to the attached Figure 4 An opening 11 is provided on one side of the processing table 10, and the opening 11 is used for the fork arm lift 41 to pass through.

[0043] In this embodiment, the opening 11 is designed to cooperate with the translational movement of the fork-arm lift 41 . When the translation assembly 43 drives the fork-arm lift 41 to move, the fork-arm lift 41 can smoothly enter and exit the internal space of the processing table 10 through the opening 11 .

[0044] Optional, please refer to the attached Figure 1The translation assembly 43 also includes a reducer 433 connected to one side of the bottom of the processing table 10 and connected to the rod body of the screw rod 431, and the input end of the reducer 433 is connected to the motor 434.

[0045] In this embodiment, the motor 434 converts electrical energy into rotational mechanical energy output, and the reducer 433 reduces the speed of the motor output according to its internal gear ratio, and increases the torque proportionally. The power adjusted by the reducer 433 is transmitted to the screw rod 431, so that the screw rod 431 can rotate at a suitable speed and torque, driving the sliding plate 432 and the fork arm lift 41 to move smoothly.

[0046] Optional, please refer to the attached Figure 1 and 4 The translation assembly 43 also includes a protrusion 435 connected to an end of the screw rod 431 away from the motor 434, and the protrusion 435 is connected to the outer surface of the processing table 10.

[0047] In this embodiment, the boss 435 plays the role of supporting the other end of the screw rod 431, so that the screw rod 431 has a stable support point during the rotation process. It is connected to the outer surface of the processing table 10, and together with the side of the reducer 433 installed at the bottom of the processing table, it forms a two-point support for the screw rod 431 to ensure the coaxiality and stability of the screw rod 431 during the transmission process. The existence of the boss 435 enhances the structural stability of the translation assembly 43, reduces the shaking and deformation of the screw rod 431 during rotation, and prolongs the service life of the screw rod 431 and the entire translation assembly. At the same time, it also improves the stability of the translation movement of the fork arm lift 41, which is conducive to improving the accuracy and reliability of the mold changing process.

[0048] Optional, please refer to the attached Figure 4 A guide rod 436 is connected to the inside of the protrusion 435 , and one end of the guide rod 436 away from the protrusion 435 passes through the bottom end of the processing table 10 and is connected to the inner wall of the processing table 10 .

[0049] In this embodiment, the guide rod 436 cooperates with the sliding plate 432. When the screw rod 431 rotates to drive the sliding plate 432 to move, the guide rod 436 limits the sliding plate 432 to only move in a straight line along its axial direction, preventing the sliding plate 432 from shifting or shaking during the movement, thereby ensuring the accuracy of the translational movement of the fork arm lift 41.

[0050] Optional, please refer to the attached Figure 4 A groove 4321 is provided at the bottom of the sliding plate 432, and a universal wheel 4322 is connected to the groove body of the groove 4321. The universal wheel 4322 is used to slide with the supporting surface of the device.

[0051] In this embodiment, when the sliding plate 432 moves under the drive of the screw rod 431, the universal wheel 4322 rolls on the supporting surface of the device. The universal wheel 4322 can turn freely and can adapt to the different direction changes of the sliding plate 432 during the movement. At the same time, the rolling friction greatly reduces the movement resistance compared with the sliding friction.

[0052] Optionally, please refer to the accompanying drawings, a first electromagnet 441 is connected to the plate body of the support plate 44 , and the first electromagnet 441 is used to connect to the lower mold 42 .

[0053] In this embodiment, the first electromagnet 441 generates a magnetic field when it is energized, generating an adsorption force on the lower mold 42, so that the lower mold 42 is firmly connected to the support plate 44. When the power is off, the magnetic field disappears, the adsorption force is released, and the lower mold 42 can be separated from the support plate 44. Compared with the traditional bolt connection method, the lower mold 42 and the support plate 44 are connected by electromagnet adsorption, which greatly simplifies the installation and disassembly process of the mold, shortens the mold change time, improves work efficiency, and avoids the unstable mold connection caused by loose bolts and other problems, thereby improving the safety and reliability of the production process.

[0054] Optionally, please refer to the accompanying drawings, a second electromagnet 241 is connected to the plate body of the lifting plate 32 , and the lifting plate 32 is connected to the upper mold 33 through the second electromagnet 241 .

[0055] In this embodiment, similar to the first electromagnet 441, the second electromagnet 241 generates an adsorption force when energized, and tightly adsorbs the upper mold 33 on the lifting plate 32. When the power is off, the adsorption force disappears, and the upper mold 33 is separated from the lifting plate 32. The application of the second electromagnet 241 simplifies the installation and disassembly process of the upper mold 33, improves the mold change efficiency, and ensures the firmness of the connection between the upper mold 33 and the lifting plate 32 during the working process, which helps to improve the mold clamping accuracy and product quality, and reduce production failures caused by mold connection problems.

[0056] Based on the same inventive concept, this embodiment also provides a method for quickly changing molds for automobile parts manufacturing molds, comprising the following steps:

[0057] Disassembling the upper mold: starting the power-off procedure of the second electromagnet 241 connected to the upper mold 33, so that the upper mold 33 is separated from the lifting plate 32, and the lifting plate 32 is controlled to rise by the cylinder 31 to lift the upper mold 33 to a certain height;

[0058] Disassembling the lower mold: starting the motor 434, the motor 434 drives the screw 431 to rotate through the reducer 433, the screw 431 drives the sliding plate 432 to move along the guide rod 436, so that the fork arm lift 41 is translated to the outside of the processing table 10 through the opening 11 of the processing table 10; controlling the fork arm lift 41 to descend, lowering the height of the support plate 44 and the lower mold 42; starting the power-off procedure of the first electromagnet 441 connected to the lower mold 42, so that the lower mold 42 is separated from the support plate 44;

[0059] Installing a new lower mold: placing a new lower mold 42 on the support plate 44, starting the first electromagnet 441, so that the first electromagnet 441 is energized to adsorb the new lower mold 42; controlling the fork-arm lift 41 to rise, and lifting the new lower mold 42 to a suitable height; starting the motor 434 in reverse, so that the screw rod 431 rotates in the reverse direction, driving the sliding plate 432 to move in the reverse direction along the guide rod 436, and translating the fork-arm lift 41 through the opening 11 to the working position inside the processing table 10;

[0060] Installing a new upper mold: The lifting plate 32 is controlled by the cylinder 31 to descend to the installation position of the new upper mold 33, and the second electromagnet 241 is started so that the second electromagnet 241 is energized to adsorb the new upper mold 33.

[0061] The above is an exemplary description of the present invention in combination with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as such non-substantial improvements are made by adopting the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
