Description

Technical Field

[0001] This utility model belongs to the field of compression molding machine technology, specifically a material discharge mechanism for a compression molding machine. Background Technology

[0002] Compression molding machines are efficient and multifunctional mechanical devices that apply pressure to raw materials such as powders, granules, or sheets at high temperatures, causing them to soften, melt, and fill the mold cavity, and finally cool and solidify into products with the desired shape and properties.

[0003] When precious metal powder is processed, its density and strength are increased by pressing it into briquettes, which facilitates its full melting during smelting and prevents it from floating on the surface of molten iron, thereby improving smelting efficiency. After the precious metal powder is pressed in the molding machine, it needs to be discharged. The existing discharge mechanism of the molding machine generally ejects the finished product from the inside of the lower mold and then removes it to complete the discharge. Although this method can discharge the finished product, the discharge process is cumbersome, and it is necessary to wait for the finished product to be removed before the precious metal powder can be refilled. Therefore, it needs to be improved. Utility Model Content

[0004] The purpose of this invention is to address the above problems by providing a discharge mechanism for a compression molding machine, which has the advantage of rapid discharge.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a discharge mechanism for a pressing and molding machine, comprising a worktable, a top plate fixedly installed on the top of the worktable, a fixed mold frame fixedly sleeved inside the right side of the top plate, a support column fixedly installed on the right side of the bottom of the inner surface of the worktable, an installation column fixedly installed in the middle of the bottom of the inner surface of the worktable, a servo motor fixedly sleeved inside the installation column, a rotating shaft fixedly connected to the other end of the output shaft of the servo motor, a disc fixedly sleeved on the outer surface of the rotating shaft, a movable mold frame fixedly sleeved inside the disc, the top and bottom of the movable mold frame being movably connected to the outer surfaces of the fixed mold frame and the support column, a mounting bracket fixedly installed on the front side of the bottom of the top plate, a lifting plate movably sleeved between the mounting brackets, a first spring fixedly connected to the top of the lifting plate, the top end of the first spring being fixedly connected to the bottom of the top plate, vertical plates fixedly installed on both the front and rear sides of the bottom of the lifting plate, a round shaft fixedly sleeved between the bottom of the vertical plates, and a ball movably sleeved on the outer surface of the round shaft.

[0006] As a preferred embodiment of this utility model, an installation block is fixedly installed on the top of the top plate, and a pneumatic cylinder is fixedly sleeved inside the installation block.

[0007] As a preferred embodiment of this utility model, the bottom end of the pneumatic cylinder is fixedly connected to an mounting plate, and the bottom of the mounting plate is fixedly connected to an upper mold.

[0008] As a preferred embodiment of this utility model, a limiting rod is movably sleeved inside the mounting plate, and the bottom of the limiting rod is fixedly connected to the top of the top plate.

[0009] As a preferred embodiment of this invention, a collection box is movably installed inside the front of the workbench, and movable doors are hinged to both the left and right sides of the front of the collection box.

[0010] As a preferred embodiment of this utility model, a first handle is fixedly connected to the front of the collection box, and there are two movable doors, each with a second handle fixedly installed on its front.

[0011] As a preferred embodiment of this utility model, baffles are hinged to both the front and rear sides of the inside of the collection box, and a second spring is fixedly connected to the bottom of the baffle. The other end of the second spring is fixedly connected to the inner surface of the collection box.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] This invention, by setting up a support column, a servo motor, a rotating shaft, and a movable mold frame, allows the operator to activate the servo motor after the precious metal powder is pressed. This causes the rotating shaft to rotate the disc 90 degrees, which in turn causes the movable mold frame to rotate. This causes the metal block inside the movable mold frame to detach from the top of the support column. The rotation of the disc then moves the next movable mold frame without a metal block inside to the top of the support column, allowing for the continued filling of precious metal powder. This improves both the discharge efficiency and the pressing efficiency of the precious metal powder. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figures 1 to 5 As shown, this utility model provides a discharge mechanism for a compression molding machine, including a worktable 1. A top plate 2 is fixedly installed on the top of the worktable 1. A fixed mold frame 3 is fixedly sleeved inside the right side of the top plate 2. A support column 4 is fixedly installed on the right side of the bottom of the inner surface of the worktable 1. An installation column 5 is fixedly installed in the middle of the bottom of the inner surface of the worktable 1. A servo motor 6 is fixedly sleeved inside the installation column 5. A rotating shaft 7 is fixedly connected to the other end of the output shaft of the servo motor 6. A disc 8 is fixedly sleeved on the outer surface of the rotating shaft 7. A movable mold frame 9 is fixedly sleeved inside the disc 8. The top and bottom of the movable mold frame 9 are movably connected to the outer surfaces of the fixed mold frame 3 and the support column 4, respectively. An installation bracket 10 is fixedly installed on the front side of the bottom of the top plate 2. A lifting plate 11 is movably sleeved between the installation brackets 10. The top of the lifting plate 11 is fixedly... A first spring 12 is fixedly connected to the top of the top plate 2. Vertical plates 13 are fixedly installed on both the front and rear sides of the bottom of the lifting plate 11. A round shaft 14 is fixedly sleeved between the bottom of the vertical plates 13. A ball 15 is movably sleeved on the outer surface of the round shaft 14. The bottom of the ball 15 is lower than the bottom of the movable mold frame 9, so that the ball 15 can push the metal block inside the movable mold frame 9 downward under the elastic force of the first spring 12, thereby causing the metal block to detach from the interior of the movable mold frame 9. After the precious metal powder is pressed into a metal block, the operator can start the servo motor 6 to make the rotating shaft 7 drive the disc 8 to rotate, thereby causing the movable mold frame 9 to detach from the upper surface of the support column 4, thereby causing the metal block to detach from the top of the support column 4.

[0022] The top plate 2 has a mounting block 16 fixedly installed on its top, and a pneumatic cylinder 17 is fixedly sleeved inside the mounting block 16. By setting the mounting block 16, the mounting block 16 can play the role of installing and fixing the pneumatic cylinder 17, thereby ensuring that the pneumatic cylinder 17 can operate stably.

[0023] The bottom end of the pneumatic cylinder 17 is fixedly connected to the mounting plate 18, and the bottom of the mounting plate 18 is fixedly connected to the upper mold 19. When the pneumatic cylinder 17 is started, it will drive the mounting plate 18 to move downward, thereby causing the upper mold 19 to move downward and insert into the interior of the fixed mold frame 3, so as to press and form the precious metal powder.

[0024] The mounting plate 18 is internally fitted with a limiting rod 20, and the bottom of the limiting rod 20 is fixedly connected to the top of the top plate 2. By setting the limiting rod 20, the mounting plate 18 can move along the outer surface of the limiting rod 20 when it rises or falls, thereby making the mounting plate 18 move more stably and ensuring that the pressing process can be carried out stably.

[0025] The workbench 1 has a collection box 21 installed inside its front side. The collection box 21 has hinged doors 22 on both the left and right sides of its front side. Due to the design of the collection box 21, the formed metal block can fall into the collection box 21 and be collected. The operator can take out the metal block by opening the doors 22.

[0026] The collection box 21 has a first handle 23 fixedly connected to its front, and there are two movable doors 22. Each of the two movable doors 22 has a second handle 24 fixedly installed on its front. The operator can open the movable door 22 by pulling the second handle 24 outward, and then take out the metal block collected inside the collection box 21. Alternatively, the operator can pull the first handle 23 outward to take out the entire collection box 21.

[0027] The collection box 21 has baffles 25 hinged to both the front and rear sides. A second spring 26 is fixedly connected to the bottom of the baffle 25, and the other end of the second spring 26 is fixedly connected to the inner surface of the collection box 21. When the metal block falls, it will contact the upper surface of the baffle 25, causing the baffle 25 to rotate downwards. This causes the second spring 26 to be compressed. After being compressed, the second spring 26 can generate a reverse elastic force under the elastic recovery action, thereby buffering the impact force generated when the metal block falls and protecting the metal block.

[0028] Working principle and usage process of this utility model:

[0029] First, the operator fills the fixed mold frame 3 and the movable mold frame 9 with precious metal powder. Then, by activating the pneumatic cylinder 17, the upper mold 19 moves downward, thus pressing the precious metal powder. After pressing, the upper mold 19 resets. At this time, the operator activates the servo motor 6, causing the rotating shaft 7 to drive the disc 8 to rotate 90 degrees. This moves the movable mold frame 9 at the top of the support column 4 above the collection box 21. The movable mold frame 9 without metal blocks inside moves above the support column 4, thus discharging the metal blocks and allowing the operator to continue filling with precious metal powder. When the movable mold... When the frame 9 moves the metal block and contacts the ball 15, the first spring 12 will push the lifting plate 11 downward under the elastic recovery action, causing the ball 15 to push the metal block downward, causing the metal block to leave the interior of the movable mold frame 9 and fall onto the upper surface of the baffle 25. At this time, the metal block will drive the baffle 25 to rotate downward, thereby compressing the second spring 26. After being compressed, the second spring 26 can generate a reverse elastic force under the elastic recovery action, thereby buffering the impact force generated when the metal block falls, protecting the metal block, and allowing the metal block to fall safely into the collection box 21.
