[0021] 3. The vehicle body is equipped with a lifting drive component, which can drive the bottom plate and the powder box on the bottom plate and the opening and closing drive component to rise or fall synchronously. When the material cart device moves along the material cart track, the bottom plate rises to avoid interference with the powder press components below the material cart device and reduce wear on the bottom plate. When the material cart device moves to the mold, the lifting drive component drives the bottom plate to fall, so that the bottom plate fits against the mold. The powder is less likely to spill out when it enters the mold from the powder box, further ensuring environmental hygiene. Attached Figure Description

Detailed Implementation

[0029] The present invention will be further described below with reference to the accompanying drawings.

[0030] This embodiment discloses a material cart device 1000, which is used for feeding powder into a powder press. (Refer to...) Figure 1 and Figure 2 The material cart device 1000 includes a cart body 100, a powder box 200, a base plate 300, and an opening and closing drive component 400. The cart body 100 is used to move and cooperate with the material cart track. The powder box 200 is set inside the cart body 100 and can move inside the cart body 100. The base plate 300 is set at the bottom of the cart body 100, and the opening and closing drive component 400 is set on the base plate 300.

[0031] The vehicle body 100 has a rectangular shell structure to accommodate a powder box 200. A release agent nozzle 500 and a pneumatic gripper 600 are connected to the front side of the vehicle body 100 (i.e., the side of the vehicle body 100 closest to the mold). The release agent nozzle 500 is used to spray release agent into the mold so that the product can be demolded after molding. Two pneumatic grippers 600 are arranged opposite each other, and the two grippers 600 can move towards each other to clamp the molded product, thereby removing the product from the mold and transporting it away.

[0032] A scraper 700 is also provided on the front side of the vehicle body 100. The lower edge of the scraper 700 is flush with the lower edge of the vehicle body 100. The scraper 700 is used to clean the powder press located below the vehicle body 100. Specifically, the scraper 700 can adopt a structure of superimposed wool felt and rigid plate to improve the cleaning effect.

[0033] The side of the vehicle body 100 is provided with a track limiting structure 800 for sliding engagement with the material cart track. The vehicle body 100 engages with the material cart track through the side track limiting structure 800, thereby facilitating the movement of the vehicle body 100 on the material cart track. Specifically, in this embodiment, the material cart track is a long strip track with a groove along its length, and the track limiting structure 800 is a slider that engages with the material cart track.

[0034] Reference Figure 3 and Figure 4In this embodiment, the powder box 200 is used to hold powder. The powder box 200 is a hollow box-shaped component with an open upper side. The upper side of the vehicle body 100 has a feed inlet 110 facing the inner cavity of the powder box 200, so that the powder can be added into the powder box 200 from the upper side of the vehicle body 100. The bottom of the powder box 200 has a discharge port 210, through which the powder in the powder box 200 can flow out of the powder box 200.

[0035] Combination Figure 5 The base plate 300 has a powder outlet 310, which is offset from the material discharge port 210. Initially, the material discharge port 210 is attached to the upper side of the base plate 300 and is blocked by the base plate 300. The driving end of the opening and closing drive component 400 is connected to the powder box 200. The opening and closing drive component 400 can drive the powder box 200 to move, so that the material discharge port 210 is aligned with the powder outlet 310 to discharge the powder in the powder box 200 into the mold.

[0036] In this embodiment, the vehicle body 100, carrying the powder box 200, the opening and closing drive unit 400, and the base plate 300, travels along the material cart track for feeding. The powder box 200 can be driven by the opening and closing drive unit 400 to move within the vehicle body 100. When the powder box 200 is loaded with powder, the discharge port 210 at the bottom of the powder box 200 is offset from the powder outlet 310 on the base plate 300 and fits against the base plate 300. Thus, the discharge port 210 is blocked by the base plate 300, making it less likely for powder to spill onto the material cart track during feeding, reducing powder loss during feeding, ensuring feeding accuracy, maintaining environmental hygiene, and preventing spilled powder from affecting the movement of the vehicle body 100 on the material cart track. When the material cart device 1000 moves above the mold, the opening and closing drive component 400 drives the powder box 200 to move, so that the discharge port 210 is aligned with the powder outlet 310 on the base plate 300, and the powder in the powder box 200 falls into the mold to realize the discharge.

[0037] Reference Figure 3 and Figure 5 In this embodiment, the base plate 300 includes a material cart friction plate 320 and a powder box friction plate 330. The material cart friction plate 320 is fixedly connected to the bottom of the powder box friction plate 330. The edge of the discharge port 210 of the powder box 200 is attached to the upper side of the powder box friction plate 330, and the powder outlet 310 passes through both the powder box friction plate 330 and the material cart friction plate 320.

[0038] The powder box friction plate 330 and the material cart friction plate 320 are made of different materials. Specifically, in this embodiment, the powder box friction plate 330 is made of stainless steel, while the material cart friction plate 320 is made of polytetrafluoroethylene (PTFE), thereby enhancing the wear resistance of the underside of the base plate 300 while maintaining the structural strength of the base plate 300. Furthermore, in other embodiments, the powder box friction plate 330 and the material cart friction plate 320 may also be made of other suitable materials.

[0039] In this embodiment, the opening / closing drive component 400 includes an opening / closing cylinder, which is parallel to the base plate 300. The cylinder body of the opening / closing cylinder is fixed to the base plate 300, and the piston rod of the opening / closing cylinder is connected to the powder box 200. The powder outlet 310 is located on the side of the opening / closing cylinder closest to the powder box 200. When the piston rod of the opening / closing cylinder extends, the opening / closing cylinder pushes the powder box 200 away from the powder outlet 310, and the powder box 200 stops discharging powder. When the piston rod of the opening / closing cylinder retracts, the opening / closing cylinder moves the powder box 200 above the powder outlet 310, so that the feeding port 210 is aligned with the powder outlet 310.

[0040] In addition, in other embodiments, the opening and closing drive 400 may also be an electric cylinder, a rack and pinion, or other suitable linear drive.

[0041] Reference Figure 2 and Figure 5 The base plate 300 is provided with guide rails 340, one on each side of the piston rod of the opening and closing cylinder. The guide rails 340 are parallel to the opening and closing cylinder. Guide blocks 230 are protruding on opposite sides of the powder box 200 facing the guide rails 340. The guide blocks 230 are slidably engaged between the two guide rails 340. Through the sliding engagement of the guide blocks 230 and the guide rails 340, the powder box 200 moves more stably and smoothly within the vehicle body 100.

[0042] In this embodiment, the powder box 200 and the guide block 230 are integrally formed to enhance the strength of the powder box 200.

[0043] The powder box 200 is funnel-shaped, gradually decreasing in size from top to bottom. That is, the area of ​​the discharge port 210 on the lower side of the powder box 200 is smaller than the area of ​​the open part on the upper side of the powder box 200. This allows the powder in the powder box 200 to flow out smoothly, ensuring the accuracy of weighing and feeding.

[0044] The powder cassette 200 is also connected to a vibration mechanism 220, which vibrates the powder cassette 200 so that powder residue on the powder cassette 200 can fall off the inner wall of the powder cassette 200 when the powder is being discharged, thus reducing powder residue in the powder cassette 200. Specifically, in this embodiment, the vibration mechanism 220 is a pneumatic vibration. In other embodiments, the vibration mechanism 220 may also be an electric vibration.

[0045] Reference Figure 1 and Figure 2 The vehicle body 100 is also equipped with a lifting drive component 120. The drive end of the lifting drive component 120 is connected to the base plate 300. The lifting drive component 120 can drive the base plate 300 to rise and fall relative to the vehicle body 100.

[0046] In this embodiment, since the opening and closing drive component 400 is set on the base plate, and the two sides of the powder box 200 are connected to the guide rail through the guide block 230, the lifting drive component 120 can drive the base plate 300 and the powder box 200 on the base plate 300 and the opening and closing drive component 400 to rise or fall synchronously. Thus, when the material cart device 1000 moves along the material cart track, the base plate 300 rises to avoid interference with the powder press components below the material cart device 1000, reducing the wear of the base plate 300. When the material cart device 1000 moves to the mold, the lifting drive component 120 drives the base plate 300 to fall, so that the base plate 300 fits against the mold. The powder is less likely to spill out during the process of entering the mold from the powder box 200, further ensuring environmental hygiene.

[0047] In this embodiment, the lifting drive component 120 is specifically a cylinder, with its cylinder body fixed to the vehicle body 100 and its piston rod fixed to the base plate 300. Furthermore, in other embodiments, the lifting drive component 120 may also be other suitable linear drive mechanisms.

[0048] Multiple lifting drive components 120 are provided to make the base plate 300 more stable when it is raised and lowered. In this embodiment, four lifting drive components 120 are specifically shown in a rectangular shape distributed on the upper side of the base plate 300.

[0049] An elastic tension member 130 connects the vehicle body 100 and the base plate 300, providing a pulling force to the base plate 300 towards the vehicle body 100. The elastic tension member 130 is positioned on the side of the opening / closing drive member 400 facing the powder box 200. This balances the force on the base plate 300, preventing one end of the base plate 300 from being heavier than the other end due to the opening / closing drive member, thus avoiding tilting of the base plate 300 relative to the lifting drive member 120 and preventing the piston rod of the lifting drive member 120 from retracting properly.

[0050] In this embodiment, the elastic tension member 130 includes a tension spring, which is connected between the vehicle body 100 and the floor 300. Multiple tension springs are provided so that the force exerted by the tension spring on the vehicle body 100 is more uniform.

[0051] Reference Figure 1 A limit switch 140 is provided on the vehicle body 100, and the limit switch 140 is located on the side of the base plate 300 facing the vehicle body 100 and directly opposite the base plate 300. The limit switch 140 is a trigger-type switch, used only to control the start and stop of the lifting drive component 120. When the lifting drive component 120 moves the base plate 300 downward, there is a gap between the limit switch 140 and the base plate 300. When the lifting drive component 120 moves the base plate 300 upward to the point where the limit switch 140 is triggered, the lifting drive component 120 stops rising, thereby limiting the height to which the base plate 300 rises.

[0052] Reference Figure 2 and Figure 3 The vehicle body 100 is also equipped with a solenoid valve assembly 150. The pneumatic gripper 600, the opening and closing drive component 400 and the lifting drive component 120 are all connected to the solenoid valve assembly 150. The extension and retraction of the solenoid valve assembly 150, the pneumatic gripper 600 and the opening and closing drive component 400 are controlled by the solenoid valve assembly 150. At the same time, the solenoid valve assembly 150 can remotely control the switching of each air circuit through the controller, thereby remotely controlling the material cart device 1000 to work.

[0053] The above description is only a preferred embodiment of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included in the scope of the present utility model patent application.
