This not only wastes raw materials but also increases production costs. Utility Model Content

Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0029] In one embodiment of this utility model, such as Figures 1-3 As shown, a novel injection molding machine feeding mechanism 2 is provided, including a base 1, a feeding mechanism 2 and a moving mechanism 3. The feeding mechanism 2 is disposed on the moving mechanism 3, and the moving mechanism 3 is disposed on the base 1.

[0030] The base 1 has a groove 11 at the bottom, and the feeding mechanism 2 is movably disposed in the groove 11.

[0031] The feeding mechanism 2 includes a feeding cylinder 21, a feeding pipe 22, a fixed plate 23, and fixing components. The feeding pipe 22 is fixedly connected to the bottom side of the feeding cylinder 21, and the fixed plate 23 is fixedly connected to the outside of the feeding pipe 22 and is disposed on the moving mechanism 3. The fixing components are sequentially disposed on the fixed plate 23 and the moving mechanism 3. The feeding pipe 22 is movably disposed within the slide groove 11.

[0032] The moving mechanism 3 includes a slide rail 31, a slider 32, a slide block 33, and a slide sleeve 34. The slide rail 31 is fixedly connected to the base 1, and the slider 32 is slidably connected to the slide rail 31. The slide block 33 is fixedly connected to both the slider 32 and the slide sleeve 34. A fixed plate 23 is disposed on the slide sleeve 34, and fixing members are sequentially inserted through the fixed plate 23 and the slide sleeve 34.

[0033] The novel injection molding machine feeding mechanism 2 provided in this application, by setting a moving mechanism 3, allows the operator to easily move the slide block 33 via the handle 35, causing the feeding mechanism 2 to slide on the slide rail 31. At the same time, the feeding pipe 22 can also move within the slide groove 11 of the base 1, thereby realizing the position adjustment of the feeding mechanism 2. Whether changing injection molds of different specifications or in different working scenarios, the feeding pipe 22 can be quickly and accurately aligned with the mold's feed port, improving the convenience of feeding position adjustment, reducing the operator's workload and debugging time, avoiding problems such as poor material conveying and spillage caused by inaccurate feeding position, reducing raw material waste and equipment downtime, making the injection molding production process smoother and more efficient, and effectively improving overall production efficiency.

[0034] In another embodiment of this utility model, the feed cylinder 21 is funnel-shaped. The funnel-shaped structure is wider at the top and narrower at the bottom. After the material is poured into the feed cylinder 21, due to the inclination angle of the cylinder wall, it can more smoothly converge to the bottom under its own gravity and quickly enter the feed pipe 22, reducing the residence time of the material in the cylinder and improving the feeding efficiency.

[0035] In another embodiment of this utility model, one end of the feed pipe 22 is fixedly connected to the feed cylinder 21, and the other end is provided with a flange 25, which is fixedly connected to the bottom side of the feed pipe 22. By providing the flange 25, it is convenient to connect to the injection molding machine or injection mold.

[0036] In another embodiment of this utility model, multiple fixing members are provided and evenly distributed on the fixing plate 23; the fixing members are fixing bolts 24, which are sequentially threaded to the fixing plate 23 and the sliding sleeve 34. By providing multiple fixing bolts 24, the stability of the connection of the fixing plate 23 is improved.

[0037] In another embodiment of this utility model, two slide rails 31 are provided, both of which are fixedly connected to the base 1. The two slide rails 31 are arranged in parallel and opposite directions. There are two sliders 32, the same as the number of slide rails 31. The slide block 33 is fixedly connected to the two sliders 32 respectively. The structure of double slide rails 31 and double sliders 32 forms a stable support structure, which can better distribute the force on the feeding mechanism 2 during the movement compared with a single slide rail 31.

[0038] In another embodiment of this utility model, positioning holes 4 are provided on the slide block 33, the slider 32, and the slide rail 31, and positioning bolts 5 are provided on the positioning holes 4. The positioning bolts 5 are threadedly connected to the positioning holes 4. During injection molding production, the feed pipe 22 needs to be precisely aligned with the mold feed port. The positioning holes 4 and the positioning bolts 5 cooperate to allow the operator to move the slide block 33 and the feeding mechanism 2 to a designated position, and then fix the slider 32 and the slide block 33 at a specific position on the slide rail 31 by tightening the positioning bolts 5. This avoids feeding deviation caused by slight displacement, ensures accurate feeding position, and guarantees that the material is smoothly delivered into the mold.

[0039] In another embodiment of this utility model, a handle 35 is provided on the side of the slide 33, and the handle 35 is fixedly connected to the slide 33. The handle 35 provides the operator with a direct point of force application. When it is necessary to adjust the position of the feeding mechanism 2, the operator only needs to hold the handle 35 to easily push the slide 33, causing the slider 32 to slide on the slide rail 31, thereby realizing the movement of the feeding mechanism 2.

[0040] The novel injection molding machine feeding mechanism 2 provided in this application operates as follows:

[0041] In actual use, when the position of the feeding mechanism 2 needs to be adjusted, the operator first loosens the positioning bolt 5, and then pushes the slide block 33 through the handle 35. The slide block 33 drives the slider 32 to slide on the slide rail 31, and at the same time, the feeding pipe 22 also moves in the slide groove 11 of the base 1, thereby realizing the horizontal position adjustment of the feeding mechanism 2. After the feeding mechanism 2 moves to the appropriate position, tighten the positioning bolt 5 to fix the moving mechanism 3, ensuring that the feeding pipe 22 is accurately aligned with the injection mold inlet. When connecting the feeding pipe 22 to the injection mold, align the flange 25 at the bottom of the feeding pipe 22 with the flange 25 of the mold inlet, and fix the two together with bolts to ensure the sealing and stability of the connection.

[0042] The novel injection molding machine feeding mechanism 2 provided in this application, by setting a moving mechanism 3, allows the operator to easily move the slide block 33 via the handle 35, causing the feeding mechanism 2 to slide on the slide rail 31. At the same time, the feeding pipe 22 can also move within the slide groove 11 of the base 1, thereby realizing the position adjustment of the feeding mechanism 2. Whether changing injection molds of different specifications or in different working scenarios, the feeding pipe 22 can be quickly and accurately aligned with the mold's feed port, improving the convenience of feeding position adjustment, reducing the operator's workload and debugging time, avoiding problems such as poor material conveying and spillage caused by inaccurate feeding position, reducing raw material waste and equipment downtime, making the injection molding production process smoother and more efficient, and effectively improving overall production efficiency.

[0043] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
