Description

Technical Field

[0001] This utility model relates to the field of medical structural component manufacturing technology, and in particular to a powder injection device for manufacturing medical structural components. Background Technology

[0002] The powder injection molding apparatus for manufacturing medical structural components is a device based on powder injection molding technology used to produce medical structural components, and has the following structure:

[0003] 1. Feeding cylinder: The feeding cylinder is the part of the device used to store powder raw materials. It is usually designed as a cylindrical structure with a certain height to ensure that the raw materials are smoothly conveyed to the conveying mechanism under the action of gravity.

[0004] 2. Conveying mechanism: mainly composed of a series of conveying elements, its function is to transport the powder raw materials in the feeding cylinder to the injection mechanism;

[0005] 3. Injection mechanism: responsible for injecting the delivered powder raw materials into the mold under high pressure to form the required medical structural components.

[0006] When problems such as wear and blockage occur at the bottom of the feed cylinder, it is difficult for maintenance personnel to directly observe and repair the bottom because the feed cylinder is usually quite tall. The entire feed cylinder must be disassembled from the equipment, which is difficult and results in low work efficiency. This application proposes a solution to this problem by dividing the feed cylinder into two parts and adding an adjustment mechanism to the upper connecting cylinder for adjusting the size of the connecting cylinder opening. Utility Model Content

[0007] To address the shortcomings of existing technologies, this utility model provides a powder injection device for the production of medical structural components. It solves the technical problem that when problems such as wear and blockage occur at the bottom of the feeding cylinder, it is difficult for maintenance personnel to directly observe and repair the bottom because the feeding cylinder usually has a certain height. The entire feeding cylinder must be disassembled from the equipment, which is difficult and leads to low work efficiency.

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] A powder injection device for producing medical structural components includes a feeding cylinder. The upper surface of the feeding cylinder has a connecting cylinder for loading powder material. Four slots are formed on the upper surface of the feeding cylinder. The lower end of the connecting cylinder is engaged with the four slots. An adjustment mechanism for adjusting the opening size of the connecting cylinder is provided inside the connecting cylinder. The adjustment mechanism includes a through hole, an adjustment plate, and adjustment holes. The through hole is located inside the connecting cylinder and communicates with the outside of the connecting cylinder. The adjustment plate is slidably connected inside the through hole. Several adjustment holes are provided, all located on one side of the adjustment plate. A limiting mechanism for fixing the position of the adjustment plate is provided outside the feeding cylinder. The limiting mechanism includes a base frame, a spring, and a limiting plate. The base frame is located outside the feeding cylinder, the spring is fixedly connected inside the base frame, and the limiting plate is fixedly connected to the end of the spring. The end of the limiting plate away from the spring is engaged with the inside of the adjustment holes.

[0010] Preferably, a support shaft is fixedly installed inside the base frame, a spring is movably sleeved on the outside of the support shaft, and a limiting plate is slidably connected to the outside of the support shaft.

[0011] Preferably, a mounting ring is fixedly installed on the side of the feeding cylinder near the base frame. Four slots are opened on the outside of the mounting ring. The lower end of the base frame is snapped into the inside of the slots. A fixing mechanism for fixing the base frame is provided at the lower end of the base frame. The fixing mechanism includes a square nut and a fixing screw. The square nut is located at the lower end of the base frame, and the fixing screw is threaded into the inside of the square nut.

[0012] Preferably, the mounting ring has a round hole on one side corresponding to each slot, and the fixing screw is threaded into the inside of the square nut through the round hole.

[0013] Preferably, the lower end of the base frame has a mounting groove, and a square nut is engaged inside the mounting groove.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. When a problem occurs at the bottom of the feeding cylinder, disconnect the connection between the limit plate and the adjustment hole, and then push the adjustment plate to close the opening of the connecting cylinder. At this time, the connecting cylinder can be pulled upward to release the engagement between the connecting cylinder and the feeding cylinder. The height of the feeding cylinder is then lowered, allowing the staff to observe and clean the inside of the feeding cylinder, reducing the difficulty of the work. If there is a major problem, the feeding cylinder can be disassembled. The initial height reduction operation also facilitates the subsequent full disassembly work, reduces the difficulty of disassembly, improves maintenance efficiency, and reduces the downtime of the equipment due to malfunction.

[0016] Second, the base frame can be installed inside any of the four slots according to work requirements and fixed by fixing screws and square nuts to ensure that the adjustment mechanism and the limit mechanism are in the right position, so as to facilitate the operation of the staff and improve the convenience of work.
