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 scope of protection of the present utility model.

[0023] Example 1

[0024] like Figure 1 and Figure 2As shown, a hardware injection molding raw material conveying device includes a support frame 1. A storage and conveying assembly 2 is installed inside the support frame 1, and a protective sealing assembly 3 is connected to the top of the storage and conveying assembly 2. An observation and control assembly 4 is also provided on the top of the protective sealing assembly 3. The protective sealing assembly 3 includes a protective cover 301, a sealing ring 302, a fixing base 303, a first spring 304, a pin 305, and a lug 306. The sealing ring 302 at the bottom of the protective cover 301 enhances the sealing effect, preventing impurities and moisture from entering the storage tank 201 and affecting the raw material quality. The protective cover 301 is connected and fixed by the pin 305 and the lug 306. The protective cover 301 is connected to the storage and conveying assembly 2 by the pin 305 and the lug 306. The protective cover 301 has a detachable structure, and the protective cover 301 forms a sealed structure with the storage and conveying assembly 2 through the sealing ring 302. The pin 305 forms an elastic structure with the fixing seat 303 through the first spring 304. By providing the sealing ring 302 at the bottom of the protective cover 301, the sealing ring 302 can make the protective cover 301 have a better sealing and protection effect, thereby preventing dust, metal shavings and other impurities from entering the storage bucket 201. This avoids impurities from mixing into the raw materials, causing the surface of the hardware parts to be rough and the internal parts to have defects. At the same time, it can prevent moisture from entering, keep the raw materials dry, and prevent them from becoming less fluid and producing air bubbles during injection molding after they become damp, which would affect the molding quality and dimensional accuracy of the hardware parts. The protective cover 301 can be connected and fixed by the pin 305 and the lug 306.

[0025] like Figure 1 and Figure 3 As shown, a hardware injection molding raw material conveying device includes a storage and conveying component 2, comprising a storage tank 201, a conveying base 202, a control plate 203, a lever 204, and a limiting rod 205. Pulling the lever 204 opens the outlet of the conveying base 202, and controlling the position of the lever 204 enables quantitative material feeding. The control plate 203 and the limiting rod 205 form a locking structure, and the control plate 203 and the conveying base 202 form a sliding structure via the lever 204. The conveying base 202 is shaped like an inverted cone. Pulling the lever 204 opens the outlet at the bottom of the conveying base 202, and the position of the lever 204 can be controlled to achieve quantitative material feeding. The overall operation is simple and practical.

[0026] like Figure 1 and Figure 4As shown, a hardware injection molding raw material conveying device includes an observation and control component 4, comprising a rotating shaft 401, a mounting cover 402, a viewing window 403, a U-shaped plate 404, a second spring 405, and a protrusion 406. The mounting cover 402 can be rotated via the rotating shaft 401 to expose the viewing window 403, facilitating operator observation of the raw material in the storage bin 201, improving convenience and preventing damage to the silo environment. The mounting cover 402 forms a rotating structure with the viewing window 403 via the rotating shaft 401, and the mounting cover 402 is connected to the storage and conveying assembly via the U-shaped plate 404 and the protrusion 406. Component 2 forms a detachable structure, and the protrusion 406 forms an elastic structure with the mounting cover 402 via the U-shaped plate 404, the second spring 405, and the mounting cover 402. The mounting cover 402 is opened by rotating it via the pivot 401, thereby exposing the visualization window 403 at its bottom. The operator can observe the raw material in the storage bin 201 through the visualization window 403, so that the operator can view the raw material in the storage bin 201 through the visualization window 403 without opening the protective cover 301, which greatly improves the convenience of observation and avoids disrupting the relatively stable environment inside the silo.

[0027] Working principle: First, the metal injection molding material is injected into the storage tank 201. Then, the protective cover 301 is placed over the top of the storage tank 201. Next, the pin 305 can be moved, causing it to retract into the fixing seat 303 by compressing the first spring 304. The side of the fixing seat 303 can then be pressed tightly against the side of the ear 306. Finally, the pin 305 can be released, and it will spring out under the elastic force of the first spring 304 and insert into the ear 306, thus securing the protective cover. The cover 301 is fixed in place. Since a sealing ring 302 is also provided at the connection between the protective cover 301 and the storage bucket 201, the sealing ring 302 can make the protective cover 301 more effective in sealing and protecting it. This can prevent dust, metal shavings and other impurities from entering the storage bucket 201, and avoid impurities from mixing into the raw materials, which would cause the surface of the hardware parts to be rough and the inside to have defects. At the same time, it can prevent moisture from entering, keep the raw materials dry, and prevent them from becoming less fluid and producing air bubbles during injection molding, which would affect the molding quality and dimensional accuracy of the hardware parts.

[0028] Next, when raw materials need to be conveyed, the control lever 204 can be pulled. The control lever 204 will cause the control plate 203 to slide on the limit rod 205, which will cause the discharge port on the material conveying base 202 to be jammed. The discharge speed can be controlled by controlling the pulling length of the control lever 204. Finally, when the operator needs to observe the remaining amount of raw materials in the storage tank 201, the U-shaped plate 404 can be squeezed. The U-shaped plate 404 will cause the protrusion 406 to squeeze the second spring 405. At this time, the mounting cover 402 can be rotated through the rotating shaft 401, thereby exposing the visualization window 403 at the bottom of the mounting cover 402. The operator can observe the remaining amount of raw materials in the storage tank 201 through the visualization window 403.

[0029] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
