Description

Technical Field

[0001] This invention relates to the field of compression molding machine technology, and more specifically to a compression molding mechanism with automatic material feeding. Background Technology

[0002] A compression molding machine is a device used to process metal or ceramic powders under high pressure and normal temperature. By applying pressure in one or both directions, the material is pressed into a specific shape, thereby giving the material a certain strength under that shape. Compression molding technology is widely used in powder metallurgy, ceramic molding, and composite materials.

[0003] In the process of preparing planar ceramic targets, ceramic powder is first prepared, and then the ceramic powder is extruded into planar ceramic target blanks using a molding machine. Ceramic target molding can be performed using a fully automatic powder molding press or a conventional powder molding press. Fully automatic powder molding presses are expensive, so most manufacturers use conventional ones. Conventional molding machines often require manual feeding, and after feeding, operators need to manually level the powder with tools. This process needs to be repeated multiple times, making powder molding time-consuming, labor-intensive, and inefficient. Furthermore, it is impossible to achieve precise feeding and uniform powder distribution, leading to a tendency for the target to break after molding. Summary of the Invention

[0004] The purpose of this invention is to provide an automatic material feeding molding mechanism to solve the problem mentioned in the background art that ordinary compression molding machines cannot achieve precise material feeding and uniform material distribution by manually feeding and smoothing the material.

[0006] An automatic material feeding molding mechanism includes a molding platform with a molding cavity at the top, and a detachable material-carrying mold installed in the molding cavity. Two symmetrically arranged limiting grooves are formed on the upper surface of the molding platform at the two edges of the molding cavity. Each limiting groove contains an electric linear guide rail. The molding platform also includes a material feeding and leveling mechanism and an upper mold mechanism. The material feeding and leveling mechanism is fixedly mounted on the power bases of the two electric linear guide rails. The electric linear guide rails drive the material feeding and leveling mechanism to reciprocate above the material-carrying mold. During reciprocating movement, the material feeding and leveling mechanism evenly injects powder into the material-carrying mold and levels the powder. The upper mold mechanism is located directly above the material-carrying mold and is used to press the leveled powder into shape.

[0007] As a further aspect of the present invention: the fabric smoothing mechanism includes:

[0008] The storage frame is fixedly mounted on the power base of the two electric linear slide rails at its bottom. Several discharge channels are evenly arranged on the bottom side of the storage frame near the molding cavity. Each discharge channel is hinged with a control cover.

[0009] A scraper plate is hinged to the side of the storage frame away from the discharge channel;

[0010] A driving component is disposed between the storage box and the scraper plate, and the driving component is used to drive the scraper plate to rotate up and down.

[0011] A linkage component is disposed between the scraper plate and the control cover, and the linkage component is used to control the opening and closing of the control cover.

[0012] As a further aspect of the present invention: the linkage component includes:

[0013] A flow guide plate is fixedly mounted inside the storage frame;

[0014] The power rod has one end penetrating through the side wall of the storage frame and movably connected to the lower surface of the scraper plate via a sliding and rotating connector, and the other end is located inside the storage frame and is fixedly connected to a collection block;

[0015] Several linkage rods are evenly and fixedly connected to the side of the assembly block away from the power rod. The end of the linkage rod away from the assembly block passes through the scraper plate and is rotatably connected to the side of the control cover.

[0016] As a further embodiment of the present invention: the sliding rotating connector includes a rotating plate, one end of which is rotatably connected to the end of the power rod away from the storage frame, and the other end of which is rotatably connected to a slide block, the slide block being slidably engaged in a control groove formed on the lower surface of the scraper plate.

[0017] As a further aspect of the present invention: the driving element includes:

[0018] A rotating seat is fixedly mounted on the side wall of the storage frame;

[0019] A control cylinder is rotatably connected to the rotating base, and the telescopic end of the control cylinder is rotatably connected to the lower surface of the scraper plate via a rotating rod.

[0020] As a further aspect of the present invention: the upper mold mechanism includes:

[0021] Four hydraulic lifting rods are respectively embedded in the molding platform at the four corners of the molding cavity;

[0028] (1) By setting up a storage frame, a material spreading and leveling structure and a linkage mechanism, the material storage frame reciprocates to achieve uniform material spreading on the material-carrying mold in the molding cavity. During the material spreading, the surface of the material-carrying mold is leveled by a scraper plate, which greatly improves the material spreading efficiency. The material spreading and leveling are one process, with a high degree of mechanization, saving time and effort.

[0029] (2) The present invention uses a control cylinder as a power source. When the scraper plate flips down, the scraper plate starts to work. Under the action of the power rod and the collection block, the linkage rod will control the closing cover to open. The powder in the storage frame flows out from the discharge port of the discharge channel to fill the loading mold. The scraper plate scrapes the powder flat in real time. By setting the linkage, the kinetic energy is reasonably utilized, the investment in kinetic energy equipment is reduced, the production cost of the equipment is reduced, and energy consumption is saved.

[0040] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0041] Example 1

[0042] Please see Figure 1-7 As shown, this embodiment of the invention provides an automatic material feeding molding mechanism, including a molding platform 1 with a molding cavity 6 at the top, and a detachable material loading mold 23 installed in the molding cavity 6. The upper surface of the molding platform 1 has two symmetrically arranged limiting grooves 9 located at the two sides of the molding cavity 6. Each limiting groove 9 is provided with an electric linear slide rail (not shown in the figure). The molding platform 1 is also provided with a material feeding and smoothing mechanism and an upper mold mechanism. The material feeding and smoothing mechanism is fixedly mounted on the power base of the two electric linear slide rails, and the upper mold mechanism is located directly above the material loading mold 23.

[0043] Among them, the electric linear slide rail is used to drive the material spreading and leveling mechanism to reciprocate above the material loading mold 23. When the material spreading and leveling mechanism reciprocates, it spreads the loaded powder into the material loading mold 23 evenly and levels the powder while spreading it evenly, so as to achieve precise feeding and uniform powder distribution. After spreading, the upper mold mechanism presses the leveled powder into shape to obtain the target blank. The target produced by using this target blank is not easy to break after pressing, thus improving the quality of the target.

[0044] like Figure 2 As shown, in this embodiment, the fabric smoothing mechanism includes a material storage frame 4, a scraping plate 2, and a driving component.

[0045] The storage frame 4 is used to hold the powder to be pressed. The bottom of the storage frame 4 is fixedly set on the power seat of two electric linear slide rails. Preferably, several bullseye pulleys (not shown in the figure) are evenly arranged on the lower surface of the storage frame 4. The bullseye pulleys are rolledly connected to the upper surface of the molding platform 1. The bullseye pulleys have the function of reducing friction, making the storage frame 4 move more smoothly on the molding platform 1 and reducing the load on the electric linear slide rails. Several discharge channels 10 are evenly arranged on the bottom side of the storage frame 4 near the molding cavity 6. Each discharge channel 10 is hinged with a control cover 13. The scraper plate 2 is hinged to the side of the storage frame 4 away from the discharge channel 10. The driving component is set between the storage frame 4 and the scraper plate 2. The driving component is used to drive the scraper plate 2 to flip up and down.

[0046] In practice, two electric linear guide rails drive the storage box 4 to move back and forth along the linear guide rails above the loading mold 23 via a power base. The powder in the storage box 4 flows evenly into the loading mold 23 from several discharge channels 10. At the same time, the scraper plate 2 driven by the drive component moves back and forth synchronously with the storage box 4. The scraper plate 2 scrapes the powder flat in real time. The material spreading and flattening are carried out at the same time, which is highly mechanized, saves time and labor, and greatly improves the material spreading efficiency.

[0047] like Figure 3 As shown, in this embodiment, the driving component includes a rotating seat 12 and a control cylinder 11. The rotating seat 12 is fixedly installed on the side wall of the storage frame 4, and the control cylinder 11 is rotatably connected to the rotating seat 12. The extension and retraction end of the control cylinder 11 is rotatably connected to the lower surface of the scraper plate 2 through a rotating rod.

[0048] The extension and retraction end of the control cylinder 11 can drive the scraper plate 2 to flip up and down. When the extension and retraction end of the control cylinder 11 retracts, it drives the scraper plate 2 to flip down, thus completing the scraping process. After the scraping is completed, the extension and retraction end of the control cylinder 11 extends, driving the scraper plate 2 to flip up.

[0049] like Figure 2 As shown, in this embodiment, the upper mold mechanism includes four hydraulic lifting rods 8, a top control console 5, and an upper mold 7.

[0050] Four hydraulic lifting rods 8 are respectively embedded in the molding platforms 1 at the four corners of the molding cavity 6. The hydraulic lifting rods 8 shall not interfere with the reciprocating movement of the storage box 4 on the two electric linear slide rails. The top control console 5 is fixedly set on the top of the four hydraulic lifting rods 8. The four hydraulic lifting rods 8 lift and lower synchronously, driving the top control console 5 to lift and lower synchronously. The upper mold 7 is fixedly set at the bottom of the top control console 5. The upper mold 7 is located directly above the material loading mold 23. The upper mold 7 can be fixedly installed at the bottom of the top control console 5 by magnetic attraction, which makes it easy to replace the upper mold 7 and to adjust it by lifting or lowering.

[0051] After the material spreading and leveling mechanism evenly spreads and levels the powder, the four hydraulic lifting rods 8 are activated to move the top control console 5 downward. The top control console 5 drives the upper mold 7 downward, and the upper mold 7 presses and shapes the powder in the material carrier mold 23.

[0052] Example 2

[0053] Combination Figure 4 , Figure 5 , Figure 6 As shown, based on Embodiment 1, this embodiment provides an automatic material feeding molding mechanism with a linkage component between the scraper plate 2 and the control cover 13. The linkage component is used to control the opening and closing of the control cover 13.

[0054] Specifically, the linkage components include a guide arc plate 3, a power rod 16, a collection block 15, and several linkage rods 14; wherein, the guide arc plate 3 is fixedly mounted inside the storage frame 4, such as... Figure 4 As shown, by setting an arc-shaped guide plate 3, the powder material in the storage frame 4 is squeezed towards the discharge channel 10, so that the discharge has a certain pressure, avoiding the situation of powder material blocking the discharge channel 10, and improving the practicality of the device.

[0055] One end of the power rod 16 passes through the side wall of the storage frame 4 and is movably connected to the lower surface of the scraper plate 2 through a sliding rotating connector. The other end is located inside the storage frame 4 and is fixedly connected to the collection block 15, so that the power rod 16 can move back and forth as the scraper plate 2 rotates.

[0056] Several linkage rods 14 are evenly and fixedly connected to the side of the collection block 15 away from the power rod 16. The end of the linkage rod 14 away from the collection block 15 passes through the scraper plate 2 and is rotatably connected to the side of the corresponding control cover 13.

[0057] Preferred, such as Figure 5As shown, in this embodiment, the sliding rotating connector includes a rotating plate 18. One end of the rotating plate 18 is rotatably connected to the end of the power rod 16 away from the storage frame 4, and the other end of the rotating plate 18 is rotatably connected to a slide block 19. The slide block 19 can be slidably engaged in the control slide groove 17 opened on the lower surface of the scraper plate 2. Through the rotating plate 18, the slide block 19 and the control slide groove 17, the power rod 16 can slide when the scraper plate 2 is flipped, avoiding motion interference.

[0058] During the downward movement of the scraper plate 2 driven by the drive unit, with the cooperation of the slide block 19 and the rotating plate 18, the power rod 16 moves into the storage box 4 as the scraper plate 2 moves downward. The power rod 16 drives each linkage rod 14 to move towards the control cover 13 through the collection block 15, thereby opening the control cover 13. This allows the powder to flow out from the outlet of the discharge channel 10 while the scraper plate 2 simultaneously scrapes and flattens the material, greatly improving the efficiency of material spreading and flattening.

[0059] The scraper plate 2 can be flipped by the control cylinder 11 to use the scraping function. At the same time, the opening and closing of the cover 13 can be controlled by the linkage adjustment. The control cylinder 11 has the function of adjustable stroke to adapt to different specifications of material loading mold 23.

[0060] Example 3

[0061] like Figure 1 , Figure 8 As shown, based on Embodiment 2, this embodiment provides an automatic material feeding molding mechanism with two limiting grooves 20 respectively opened on the top of the two opposite inner walls of the molding cavity 6. A spring 21 is provided in each limiting groove 20, and a support block 24 is provided on the top of the spring 21. The support block 24 is slidably fitted in the limiting groove 20. Two support plates 22 are fixedly provided on the two opposite side walls of the material loading mold 23. The four support plates 22 are respectively placed on the top of the four support blocks 24. The length of the support plate 22 is greater than the length of the support block 24. When the upper mold 7 is lifted, the material loading mold 23 is lifted under the action of the spring 21, which makes it convenient for the staff to remove the entire material loading mold 23 and take out the product. The support plates 22 support the material loading mold 23 to avoid incomplete molding under the elastic force of the spring 21.

[0062] When using this invention, the material loading mold 23 is placed into the molding cavity 6. The electric linear slide rail is activated to make the storage frame 4 reciprocate in the molding cavity 6. When the storage frame 4 moves to the molding cavity 6, the control cylinder 11 is activated at the same time, causing the scraper plate 2 to flip down. Under the action of the power rod 16 and the collection block 15, the linkage rod 14 pushes open the control cover 13. The powder in the storage frame 4 flows out from the outlet of the discharge channel 10 to fill the material loading mold 23. The scraper plate 2 scrapes the powder flat in real time. After the material is flattened, the storage frame 4 is removed, and the hydraulic lifting rod 8 is activated to drive the upper mold 7 to press down through the top control console 5 to realize the molding operation.
