DETAILED DESCRIPTION

[0031] See also Figure 1-4 In the embodiment of the present invention, a mold for processing a bowl-shaped part includes a base 1, a fixed mold 2 is fixedly connected to the middle of the upper end of the base 1, a first bracket 4 is fixedly connected to the middle of the upper end of the base 1, an electric push rod 5 is transmission-connected to the top of the inner cavity of the first bracket 4, and the output end of the electric push rod 5 is transmission-connected to the movable mold 3, a symmetrical second bracket 6 is fixedly connected to the side of the upper end of the base 1 away from the first bracket 4, and a material discharge box 7 is fixedly connected between the symmetrical second brackets 6, and a plate 9 is placed in the material discharge box 7. A number of plates 9 are stacked in the inner cavity, and the plates 9 are squeezed downward by the elastic pressure plate in the inner cavity of the discharge box 7. After the lowest plate 9 moves out of the inner cavity of the discharge box 7, the elastic pressure plate will squeeze the plate 9 downward, thereby ensuring that there is always a plate 9 located at the bottom of the inner cavity of the discharge box 7. A feeding mechanism for pushing the plate 9 to move horizontally is provided below the discharge box 7. When the electric push rod 5 drives the movable mold 3 to move downward, the feeding mechanism remains stationary. When the electric push rod 5 drives the movable mold 3 to move upward, the feeding mechanism drives the plate 9 to approach the position of the fixed mold 2.

[0032] See also Figure 7A cavity 24 is provided in the middle of the upper end of the fixed mold 2, and a symmetrical receiving plate 10 is vertically slidably connected to the middle of the upper end of the fixed mold 2. The lower end of the receiving plate 10 is elastically connected to the inner cavity of the fixed mold 2 by a spring. The distance from the top of the receiving plate 10 to the upper end surface of the fixed mold 2 is greater than the distance from the bottom of the inner cavity of the cavity 24 to the upper end surface of the fixed mold 2. The distance between the symmetrical receiving plates 10 is less than the width of the plate 9. The plate 9 is supported by the symmetrical receiving plates 10, and after the parts are processed, the plate 9 is elastically connected to the inner cavity of the fixed mold 2 by a spring. The connected symmetrical receiving plate 10 lifts the part from the inner cavity of the cavity 24, thereby completing the demolding process. When the feeding mechanism feeds the inner cavity plate 9 of the discharge box 7 between the fixed mold 2 and the movable mold 3, the new plate 9 will contact the part on the receiving plate 10, thereby pushing the processed parts out of the fixed mold 2 and the movable mold 3, and the plate 9 will replace the position of the bowl-shaped part, thereby completing the automatic loading and realizing the automatic unloading operation, thereby improving the processing efficiency of the bowl-shaped parts.

[0033] See also Figure 10-11 The feeding mechanism includes a symmetrical driving plate 12, a symmetrical slide groove 11 is provided on the side wall of the fixed mold 2, the driving plate 12 is horizontally slidably connected to the inner cavity of the slide groove 11, and the symmetrical driving plate 12 is fixedly connected to a connecting plate 8 on one side close to the discharge box 7, and a symmetrical support rod 13 is fixedly connected to the side of the connection plate 8 away from the driving plate 12, and the upper end surface of the support rod 13 is in contact with the lower end surface of the plate 9 located at the bottom of the inner cavity of the discharge box 7, and a groove 15 is provided on the upper part of one end of the support rod 13 close to the connection plate 8, and a push block 14 is rotatably connected to the inner cavity of the groove 15 on one side close to the connection plate 8, and the middle part of the push block 14 away from the connection plate 8 is connected to the groove 1 5 are elastically connected by a spring, that is, when the support rod 13 is horizontally close to the position of the fixed mold 2, the plate 9 located at the bottom of the inner cavity of the discharge box 7 will be pushed horizontally close to the fixed mold 2 through the pushing block 14, and in the process of resetting the support rod 13, when the side of the pushing block 14 close to the connecting plate 8 contacts the plate 9, the pushing block 14 will rotate toward the bottom of the inner cavity of the groove 15, so as not to push the plate 9 away from the position of the fixed mold 2, and after the support rod 13 is reset, the pushing block 14 will be detached from the inner cavity of the groove 15 under the action of the spring elastic force and remain in a vertical state, and the length of the top of the pushing block 14 exceeding the support rod 13 is less than the height of the plate 9.

[0034] See also Figure 8-9A horizontal groove 28 is provided at the upper part of the side of the driving plate 12 away from the receiving plate 10. The horizontal length of the inner cavity of the horizontal groove 28 is the same as the distance between the side of the pushing block 14 close to the fixed mold 2 and the side of the receiving plate 10 close to the discharge box 7. A vertical groove 27 is provided at the end of the horizontal groove 28 away from the discharge box 7. A guide groove 29 is provided between the end of the horizontal groove 28 close to the discharge box 7 and the middle of the vertical groove 27, that is, the middle of the vertical groove 27 is connected to the end of the horizontal groove 28 close to the discharge box 7 through the guide groove 29. A fixed block 25 is fixedly connected to the bottom of the inner cavity of the slide 11. The side of the fixed block 25 close to the discharge box 7 is connected to the lower part of the driving plate 12. Through the elastic connection of the spring, a symmetrical driving rod 26 is fixedly connected to the middle part of the lower end of the movable mold 3, and the lower end of the driving rod 26 is slidably connected to the fixed mold 2. The lower end of the driving rod 26 is elastically connected to the side of the driving plate 12, that is, when the moving rod 32 is squeezed, it will shrink into the inner cavity of the driving rod 26, and the end of the driving rod 26 away from the moving rod 32 will slide with the inner cavity side walls of the vertical groove 27, the horizontal groove 28 and the guide groove 29. When the movable mold 3 drives the driving rod 26 and the moving rod 32 to move downward, the moving rod 32 moves vertically downward in the inner cavity of the vertical groove 27. At this time, under the action of the elastic force, the position of the driving plate 12 remains in its initial static state.

[0035] When the moving rod 32 moves upward in the inner cavity of the vertical groove 27, a first guide block 30 is provided on the upper side of the connection between the vertical groove 27 and the guide groove 29. The first guide block 30 is fixedly connected to the inner cavity of the vertical groove 27. The inclination angle of the first guide block 30 is the same as that of the guide groove 29. The end of the first guide block 30 close to the guide groove 29 is farther away from the position of the cavity 24 than the other end. That is, in the process of the moving rod 32 moving downward from the top of the vertical groove 27, when the moving rod 32 contacts the side of the first guide block 30 close to the horizontal groove 28, the moving rod 32 is squeezed and contracted into the inner cavity of the driving rod 26. When the moving rod 32 moves upward in the inner cavity of the vertical groove 27, the side wall of the moving rod 32 is blocked by the side wall of the first guide block 30 close to the guide groove 29 , so that the moving rod 32 will not shrink into the inner cavity of the driving rod 26, but will enter the inner cavity of the guide groove 29 under the guiding action of the side wall of the inclined first guide block 30, thereby relatively driving the driving plate 12 to move horizontally toward the position of the fixed mold 2, thereby driving the plate 9 to move out of the inner cavity of the discharge box 7 through the connecting plate 8, the support rod 13 and the pushing block 14, and horizontally move to the top of the symmetrical receiving plate 10, thereby pushing the processed bowl-shaped parts from the top of the symmetrical receiving plate 10 to the side away from the discharge box 7. At this time, a conveyor belt and other equipment are set on the side of the fixed mold 2 away from the discharge box 7, which can automatically transport the bowl-shaped parts detached from the symmetrical receiving plate 10, thereby automatically completing the loading of the plate 9 and the unloading of the bowl-shaped parts.

[0036] During the horizontal movement of the driving plate 12, the moving rod 32 will also continuously approach the connection between the horizontal groove 28 and the guide groove 29 from the connection between the vertical groove 27 and the guide groove 29, and the connection between the horizontal groove 28 and the guide groove 29 is fixedly connected with a second guide block 31. The side of the second guide block 31 close to the horizontal groove 28 is further away from the position of the cavity 24. The function of the second guide block 31 is the same as that of the first guide block 30, and both play a one-way limiting and guiding role on the moving rod 32. The first guide block 30 is to limit the moving rod 32 from returning to the top of the vertical groove 27, and the second guide block 31 is to limit the moving rod 32 from returning to the top of the vertical groove 27. The guide block 31 is used to prevent the moving rod 32 from returning to the guide groove 29 from the inner cavity of the horizontal groove 28. After the moving rod 32 moves into the inner cavity of the horizontal groove 28, the driving plate 12 automatically resets under the action of elastic force, thereby driving the support rod 13 and the pushing block 14 to reset. During the resetting process of the pushing block 14, the side close to the connecting plate 8 will contact the lowest plate 9 in the inner cavity of the discharge box 7. At this time, the pushing block 14 will rotate into the inner cavity of the groove 15 and reset after the pushing block 14 is separated from the plate 9, so as to facilitate the horizontal movement of the plate 9 again.

[0037] See also Figure 5 A cavity 16 is provided in the middle of the lower end of the movable mold 3, and a core 17 is fitted on the top of the inner cavity of the cavity 16. The middle of the upper end of the core 17 is transmission-connected to the output end of the electric push rod 5. Slots 21 are provided on both sides of the upper part of the core 17 near the driving rod 26. A clamping rod 20 is slidably connected to the middle of the inner cavity of the movable mold 3, and one end of the clamping rod 20 close to the vertical groove 27 is inserted into the core 17, that is, when the electric push rod 5 drives the core 17 to move downward, the core 17 and the clamping rod 20 are engaged, thereby driving the movable mold 3 to move downward synchronously. A symmetrical driven rod 18 is vertically slidably connected to the middle of the lower end of the movable mold 3. The driven rod 18 and the core 17 are located in the same vertical plane. The width of the driven rod 18 is greater than the width of the clamping rod 20. A cross groove that slides with the driven rod 18 and the clamping rod 20 is provided in the middle of the inner cavity of the movable mold 3.

[0038] See also Figure 6A U-shaped groove 19 is provided in the middle of the upper end of the driven rod 18, and a symmetrical sliding rod 22 is fixedly connected to the middle of the upper end of the inner cavity of the U-shaped groove 19. A symmetrical oblique groove 23 is provided on the outer wall of the end of the clamping rod 20 away from the core 17. The outer wall of the sliding rod 22 away from the driven rod 18 is slidably matched with the inner cavity of the oblique groove 23. In the process of the movable mold 3 moving down and approaching the fixed mold 2 as the core 17 moves down, the lower end surface of the movable mold 3 will first contact the plate 9 located above the receiving plate 10, thereby synchronously pushing the plate 9 and the receiving plate 10 to move downward, and in the process of moving downward, the lower end of the driven rod 18 will gradually approach and contact the upper end surface of the fixed mold 2, and when the plate 9 fits with the upper end surface of the movable mold 3, at this time, when the driven rod 18 and the sliding rod 22 are relatively The core 17 is moved upward in the inner cavity of the cross groove, thereby driving the clamping rod 20 to move horizontally away from the inner cavity of the clamping groove 21 through the sliding cooperation of the slide rod 22 and the inclined groove 23, so that the core 17 and the movable mold 3 are separated. At this time, the core 17 extends from the inner cavity of the cavity 16 and moves toward the position of the cavity 24, thereby squeezing the plate 9 toward the inner cavity of the cavity 24. At this time, the edge of the plate 9 remains stationary under the squeezing action of the fixed mold 2 and the movable mold 3, so that when the middle part of the plate 9 is squeezed into a bowl shape by the core 17, the edge of the plate 9 remains in the initial state without warping, which is convenient for subsequent material unloading. At the same time, when the bowl-shaped parts are cut and polished in the subsequent process, the flat edge makes it easier to fix and process the bowl-shaped parts.

[0039] The distance from the bottom of the inner cavity of the vertical groove 27 to the lower end of the first guide block 30 is greater than the distance that the receiving plate 10 extends out of the fixed mold 2, so that after the receiving plate 10 pushes the bowl-shaped demoulding and remains stationary, the driving plate 12 will drive the plate 9 to move toward the fixed mold 2, thereby ensuring that the plate 9 can stably fall on the top of the receiving plate 10, and also ensuring that the processed bowl-shaped parts can be stably pushed out of the space between the fixed mold 2 and the movable mold 3 by the plate 9. When the core 17 moves up, it will first enter the inner cavity of the cavity 16, and when the upper end of the core 17 contacts the top of the inner cavity of the cavity 16, it will then drive the movable mold 3 to move up synchronously. In the process of moving up, as the movable mold 3 is continuously Away from the position of the fixed mold 2, the driven rod 18 will also move downward relatively in the inner cavity of the cross groove under its own weight, thereby driving the clamping rod 20 to clamp in the inner cavity of the clamping slot 21 again, so that the movable mold 3 can move down with the core 17 again, thereby processing the plate 9 into a bowl-shaped mold, that is, in the process of the core 17 moving downward, the driving plate 12 and the support rod 13, and the pushing block 14 all remain stationary, and in the process of the core 17 driving the movable mold 3 to move upward, after the receiving plate 10 is reset, the driving plate 12 drives the support rod 13, the pushing block 14 and the plate 9 to move horizontally, and after the fixed mold 2 returns to its initial position, the driving plate 12 returns to its initial position again under the action of elastic force.
