Description

Technical Field

[0001] This utility model relates to the field of mold production equipment technology, and in particular to a forging processing equipment for precision mold production. Background Technology

[0002] Molds are various molds and tools used in industrial production to obtain desired products through methods such as injection molding, blow molding, extrusion, die casting, forging, smelting, and stamping. In short, molds are tools used to make shaped items. These tools are composed of various parts, and different molds are composed of different parts. With the development of industry, mold production has become more automated. Currently, molds are mostly processed by machine tools. Before forging, the mold needs to be fixed. Existing fixing mechanisms can only fix molds of one size, which reduces their practicality. Therefore, a precision mold production forging processing equipment has been promoted and used in the market.

[0003] The "Forging Processing Equipment for Precision Mold Production" disclosed in application number "202222490034.6" "includes a frame, a connecting plate, and two fixed plates. The frame is equipped with an adjustment assembly inside, and a support plate is fixedly connected to the inner wall of the frame. The bottom end of the connecting plate is attached to the inner side of the bottom end of the frame. One side of the connecting plate 12 is fixedly connected to one side of one of the fixed plates. The beneficial effects of this utility model are: the limiting rod slidably set with the limiting groove facilitates the support of the first rack plate, and the sliding rod slidably set with one of the fixed plates facilitates further support of the first rack plate. Furthermore, the sliding setting of the limiting groove and the limiting rod also limits the sliding of the second rack plate each time, thus significantly improving the stability of the first and second rack plates during movement. At the same time, the movement of the first and second rack plates can be controlled by a forward and reverse motor, and the mold body can be automatically limited subsequently." However, this device still has the following defects in actual use.

[0004] Using a gear and rack mechanism to clamp and fix the mold has poor stability and low fixing ability.

[0005] The equipment does not have a flipping function. After the upper surface of the mold is processed, the operator needs to manually disassemble it and flip it over. This process is not only very tedious and reduces work efficiency, but also reduces the processing accuracy after disassembly and reinstallation. Utility Model Content

[0006] The purpose of this invention is to provide a forging processing equipment for precision mold production, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution, which includes a lifting assembly. The lifting assembly includes a base shell, and each of the four corners inside the base shell is provided with a telescopic cylinder. The top of the telescopic rod of the telescopic cylinder is provided with a connecting plate. Several connecting plates are connected to a fixed frame by several bolts. Each of the left and right outer walls of the fixed frame is provided with a pair of telescopic cylinders. After the telescopic rod of the telescopic cylinder passes through the fixed frame, a first clamping plate is provided at the top of its telescopic rod. A placement platform is provided at the top of the base shell. The telescopic rod of the telescopic cylinder passes through the placement platform. The fixed frame is located above the placement platform. A clamping assembly is provided inside the placement platform.

[0008] As a preferred embodiment of this utility model, a pair of movable slots are symmetrically provided on the top of the placement platform, and a mounting bracket is provided on one side of the placement platform.

[0009] In a preferred embodiment of this invention, the clamping assembly includes a pair of bidirectional lead screws. The two bidirectional lead screws are movably mounted in movable slots via a pair of bearing seats. Sprockets are symmetrically arranged at the same end of the two bidirectional lead screws, and the two sprockets are connected by a chain drive. One end of one bidirectional lead screw, away from the sprocket, is located on the drive end of a first motor, which is mounted on a mounting bracket. Two pairs of driving members are symmetrically arranged on each of the two bidirectional lead screws. The driving members are located in movable slots, and each driving member is provided with a nut. The nut is threadedly connected to the bidirectional lead screw, and corresponding driving members are connected by a connecting shell. A detachable mounting plate is provided on the top of the connecting shell. A rotating shaft is movably mounted on the mounting plate. A second clamping plate is provided on the front of the rotating shaft, and the front of the second clamping plate has anti-slip textures. One end of the rotating shaft, away from the second clamping plate, is located on the drive end of a second motor, which is located on the back of the mounting plate.

[0010] As a preferred embodiment of this utility model, the top of the connecting shell is provided with a slot, and several card slots are provided on both sides of the slot. The bottom of the mounting plate is provided with an insert block, which is disposed in the slot. Several card edges are provided on both sides of the insert block corresponding to the positions of several cards.

[0011] As a preferred embodiment of this utility model, guide rails are provided on both the front and rear inner walls of the fixed frame, and sliders are symmetrically arranged on both sides of the mounting plate, with the sliders movably mounted on the guide rails.

[0012] Compared with the prior art, the above-mentioned technical solution of this utility model has the following beneficial technical effects:

[0013] 1. This utility model achieves stable clamping of the mold through the cooperation of the bidirectional lead screw, driving component, lead screw nut and connecting shell in the clamping assembly. The bidirectional lead screw drives the lead screw nut to move under the drive of the first motor, thereby causing the two connecting shells to move inward synchronously, driving the second clamping plate to clamp the mold. This mechanical structure design ensures the uniform distribution of clamping force and effectively avoids the mold from shaking or displacing during processing.

[0014] 2. This utility model further enhances the friction between the mold and the anti-slip texture set on the front of the second clamping plate. Even if a large external force is generated during the processing, the mold can be firmly fixed on the clamping device to ensure processing accuracy.

[0015] 3. In the mold processing process, when it is necessary to process the other side of the mold, the second motor drives the second clamping plate to rotate, thereby driving the mold to flip. This electric flipping method is fast and efficient, saving the time and labor of manual operation and improving the overall efficiency of mold processing.

[0016] 4. The guide rail on the inner wall of the fixed frame cooperates with the sliders on both sides of the mounting plate to play an auxiliary positioning role during the mold flipping process, ensuring that the mold can move along the predetermined track when flipping, avoiding positional deviation caused by improper flipping of the mold, and ensuring the processing position accuracy of the mold before and after flipping.

Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of the present invention more clearly understood, the present invention is further described below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are merely illustrative and are not intended to limit the scope of the present invention. Furthermore, descriptions of known structures and technologies are omitted in the following description to avoid unnecessary confusion regarding the concepts of the present invention.

[0027] like Figures 1-8 As shown, the present invention proposes a forging processing equipment for precision mold production, which mainly includes a lifting assembly 1, wherein the lifting assembly 1 includes a bottom shell 10, and telescopic cylinders 11 are installed at the four corners inside the bottom shell 10. The top of the telescopic rod of the telescopic cylinder 11 is fixed with a connecting plate 12. Multiple connecting plates 12 are stably connected to a fixed frame 14 by several bolts 13. On the left and right outer walls of the fixed frame 14, a pair of telescopic cylinders 16 are provided. The telescopic rod of the telescopic cylinder 16 can pass through the fixed frame 14, and a first clamping plate 17 is installed on its top. A placement platform 2 is provided on the top of the bottom shell 10. At the same time, the telescopic rod of the telescopic cylinder 11 passes through the placement platform 2, so that the fixed frame 14 is located above the placement platform 2. A clamping assembly 3 is also provided inside the placement platform 2.

[0028] A pair of movable slots 21 are symmetrically provided on the top of the placement platform 2, and a mounting bracket 20 is also provided on one side of the placement platform 2;

[0029] The clamping assembly 3 mainly includes a pair of bidirectional lead screws 30. The two bidirectional lead screws 30 are movably mounted in the movable slots 21 on the top of the placement platform 2 via a pair of bearing seats 31. Sprockets 32 are symmetrically mounted on the same end of the two bidirectional lead screws 30, and these sprockets 32 are connected by a chain 33. The end of one bidirectional lead screw 30 away from the sprocket 32 ​​is connected to the drive end of a first motor 34, which is mounted on the mounting bracket 20. Two pairs of driving members 35 are symmetrically arranged on each of the two bidirectional lead screws 30, located within the movable slots 21. Each driving member 35 is fitted with a nut 36, which is threadedly connected to the bidirectional lead screw 30. Corresponding driving members 35 are connected via a connecting shell 37, the top of which is equipped with a detachable mounting plate 3. 10. A rotating shaft 313 is movably mounted on the mounting plate 310. A second clamping plate 314 is fixed to the front of the rotating shaft 313. The front of the second clamping plate 314 is provided with anti-slip texture 315, which can better clamp the mold. One end of the rotating shaft 313 away from the second clamping plate 314 is connected to the transmission end of the second motor 317. The second motor 317 is mounted on the back of the mounting plate 310. A slot 38 is opened on the top of the connecting shell 37. Several slots 39 are opened on both sides of the slot 38. An insert block 311 is provided at the bottom of the mounting plate 310. The insert block 311 is set in the slot 38. Several locking edges 312 are provided on both sides of the insert block 311 corresponding to the positions of several slots 39. Through the cooperation of the slots 39 and the locking edges 312, the detachable connection between the connecting shell 37 and the mounting plate 310 is realized.

[0030] Guide rails 15 are provided on both the front and rear inner walls of the fixed frame 14, and sliders 316 are symmetrically arranged on both sides of the mounting plate 310. The sliders 316 are movably mounted on the guide rails 15. This structural design ensures that the mounting plate 310 can move smoothly during the lifting process.

[0031] First, carefully place the mold on the placement table 2, ensuring that the mold is placed accurately and stably. Then, start the first motor 34 to make it rotate forward. When the first motor 34 is running, it will drive one of the bidirectional lead screws 30 to start rotating. Due to the cooperation between the sprocket 32 ​​and the chain 33 at the tail of the bidirectional lead screw 30, the other bidirectional lead screw 30 will rotate synchronously. During this process, the nuts 36 on both sides of the bidirectional lead screw 30 will drive the drive component 35 connected to them to move inward synchronously under the rotation drive of the lead screw. As the drive component 35 moves inward, the two connecting shells 37 connected to it will also move inward synchronously, so that the second clamping plate 314 can clamp and fix the mold. Once the mold is stably clamped, the processing operation can begin.

[0032] After the upper surface of the mold is processed, several telescopic cylinders 16 are activated simultaneously to extend their telescopic rods. At this time, the first clamping plate 17 will press and clamp the mounting plate 310 under the push of the telescopic rods. Through the cooperation of the two first clamping plates 17, the mounting plate 310 is fixed. Then, several telescopic rods 1 are activated to extend from the telescopic cylinders. When the telescopic rods 1 extend, they will push up the fixing frame 14. With the cooperation and guidance of the guide rail 15, the mounting plates 310 on both sides will move and rise along the guide rail 15 with the mold. When the mold rises to a suitable height, the second motor 317 is activated. The second motor 317 drives the second clamping plate 314 to rotate, thereby causing the clamped mold to flip. After the flipping action is completed, the mold is lowered until the insert block 311 can be accurately inserted back into the slot 38. At this time, the other side of the mold is in a processable state, and the other side of the mold can be processed.

[0033] It should be understood that the specific embodiments described above are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof.
