[0014] 1. This utility model features a sealing plate with a through groove on one side and a first screw connected to the other side of the sealing plate via a U-shaped limiting hole. The first screw is threaded to the mold body. Depending on the required number of injection molded parts, the first screw is rotated counterclockwise and loosened, allowing the sealing plate to slide within the mold body until the through groove is flush with the mold cavity. The first screw is then rotated clockwise to fix the sealing plate. At this point, the entire mold cavity is unobstructed through the through groove, ensuring that the raw material fills the mold cavity during injection molding, resulting in batches of injection molded parts. When the number of remaining parts is small, the first screw is again rotated counterclockwise and loosened, allowing the sealing plate to slide within the mold body via the U-shaped limiting hole to a position offset between the through groove and the mold cavity, thus fixing the sealing plate. During injection molding, due to the closed structure of the sealing plate on one side of the mold cavity, raw material cannot flow into some parts of the mold cavity, thereby adjusting the injection volume and controlling the number of parts molded in one operation, effectively reducing the production cost of injection molding.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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 protection scope of the present utility model.

[0025] Please see Figure 1-4This utility model provides a technical solution: an adjustable injection volume mold, including a main body mechanism 1 and a limiting mechanism 2 disposed inside the main body mechanism 1 for controlling the unobstructed flow within the mold forming cavity to adjust the injection volume. The limiting mechanism 2 includes sealing plates 201 symmetrically arranged and slidably connected to the inner side of the mold body 103. The bottom of the inner side of the sealing plate 201 is movably connected to a first screw 203 through a U-shaped limiting hole 202. The outer side of the bottom end of the first screw 203 is threadedly connected to the mold body 103. A through groove 204 is provided on the other side of the inner side of the sealing plate 201. A plurality of locking blocks 205 are symmetrically arranged on one side of the sealing sheet 201. Each locking block 205 has a locking rib 206 inside it. A cover plate 207 is fixedly connected to one side of the locking rib 206. An inner sheet 208 is fixedly connected to the inside of the cover plate 207. A sealing gasket 3 is movably connected to the outside of the sealing sheet 201. A plurality of sealing gaskets 3 are symmetrically arranged. A push plate 211 is fixedly connected to one side of the sealing gasket 3. A second screw 210 is rotatably connected to the inside of the push plate 211. A base plate 209 is threadedly connected to the outside of the second screw 210. A mold body 103 is fixedly connected to the outside of the base plate 209. By adjusting the through groove 204 to coincide with or offset from the mold cavity 106, the mold cavity 106 can be switched between open and closed states. This adjusts the injection volume. Based on the required number of injection molded parts, each first screw 203 is rotated counterclockwise and loosened. This, combined with the U-shaped limiting hole 202, slides the sealing piece 201 inside the mold body 103 until the through groove 204 is flush with the mold cavity 106. The first screw 203 is then rotated clockwise to fix the position of the sealing piece 201. At this point, the entire mold cavity 106, connected by the through groove 204, achieves a through-flow mechanism. To ensure that the raw material fills the mold cavity 106 during the injection molding process, and to form injection molded parts in batches, when the number of remaining workpieces to be processed is small, the first screw 203 is rotated counterclockwise and loosened. The sealing plate 201 is slid in the mold body 103 through the U-shaped limiting hole 202 to a position offset between the through groove 204 and the mold cavity 106, and the sealing plate 201 is fixed. During the injection molding process, due to the influence of the plate-shaped closed structure on one side of the sealing plate 201, the cavity of the mold cavity 106 will not be able to receive raw material, thereby adjusting the injection volume during the processing.

[0026] In this utility model, preferably, the main body mechanism 1 includes a back plate 101, a plurality of mounting holes 102 are symmetrically arranged on the inner side of the back plate 101, a mold body 103 is fixedly connected to one side of the back plate 101, a terminal block 104 is symmetrically arranged on one side of the mold body 103, a limit pin 105 is symmetrically arranged on one side of the mold body 103, and a mold cavity 106 is arranged on the inner side of the back plate 101. The main body mechanism 1 is connected to the main body of the injection molding machine in conjunction with the mounting holes 102 symmetrically arranged in the back plate 101, and the injection molding machine drives the injection molding operation in the mold cavity 106 in the mold body 103.

[0027] In this utility model, preferably, the sealing gasket 3 is made of flexible material, and a sealing strip 201 is movably connected to one side of the sealing gasket 3, which can effectively improve the sealing performance between the edge of the sealing strip 201 and the mold body 103.

[0028] In this utility model, preferably, a buckle groove 4 is provided on the other side of the inside of the cover plate 201. The buckle groove 4 has a U-shaped structure, which can effectively facilitate personnel to remove the cover plate 207 after inserting the tool.

[0029] In this utility model, preferably, a sliding rod 5 is slidably connected to the inner side of the sealing sheet 201, and several sliding rods 5 are symmetrically arranged. One end of each sliding rod 5 is fixedly connected to the mold body 103, which can effectively ensure the stability of the sealing sheet 201 during use.

[0030] In this utility model, preferably, a washer 6 is movably connected to the outer side of the top end of the first screw 203. The washer 6 is located on one side of the limiting hole 202, which can effectively reduce the loosening range of the first screw 203 during use.

[0031] In this utility model, preferably, a scale 7 is fixedly connected to one side of the inside of the sealing sheet 201. The scale 7 is located on one side of the first screw 203. By comparing with the first screw 203, the sliding stroke of the sealing sheet 201 can be effectively indicated to the personnel.

[0032] In this utility model, preferably, the inner sheet 208 is made of tempered glass, and a cover 207 is fixedly connected to the outer side of the inner sheet 208, which effectively facilitates personnel to observe the stability of the position of the first screw 203.

[0033] The working principle and usage process of this utility model are as follows: During use, according to the required quantity of injection molded parts, rotate counterclockwise and loosen each of the first screws 203. With the help of the U-shaped limiting holes 202, slide the sealing piece 201 inside the mold body 103 until the through groove 204 is flush with the mold cavity 106. Then, rotate the first screws 203 clockwise to fix the position of the sealing piece 201. At this time, the entire mold cavity 106 is connected by the through groove 204, achieving unobstructed flow inside. This ensures that during the injection molding process, the raw material fills the mold cavity 106, resulting in the batch formation of injection molded parts. When the number of remaining workpieces to be processed is small, the first screw 203 is rotated counterclockwise and loosened. The sealing plate 201 is slid in the mold body 103 through the U-shaped limiting hole 202 to a position offset between the through groove 204 and the mold cavity 106, and the sealing plate 201 is fixed. During the injection molding process, due to the influence of the plate-shaped closed structure on one side of the sealing plate 201, the cavity of the mold cavity 106 will not be able to receive raw materials, thereby adjusting the injection volume during the processing, controlling the number of workpieces molded at one time, and effectively reducing the production cost of injection molding.
