Detailed Implementation

[0017] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0018] In the description of this utility model, it should be understood that the terms "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0019] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0020] like Figures 1-3As shown, a mold according to an embodiment of the present invention includes a mold frame 1 and a mold core 2; one side of the mold frame 1 has a receiving groove 11; the mold core 2 includes a front mold 21, a rear mold 22, a first back plate 23 and a second back plate 24, the bottom surface of the front mold 21 has a first injection groove, the top surface of the rear mold 22 has a second injection groove, the first back plate 23 is disposed on the top surface of the front mold 21, the second back plate 24 is disposed on the bottom surface of the rear mold 22, the front mold 21 is slidably connected to the top of the receiving groove 11 through the first back plate 23, and the rear mold 22 is slidably connected to the bottom of the receiving groove 11 through the second back plate 24, and as the front mold 21 and the rear mold 22 slide into the receiving groove 11, the first injection groove and the second injection groove can be closed to form an injection cavity. One mold base 1 can accommodate multiple mold cores 2. Therefore, when the mold core 2 is placed into the receiving groove 11 of the mold base 1, the first injection groove and the second injection groove together form an injection cavity. At this time, injection molding can be performed on the injection cavity to form the injection molded product. After the mold injection is completed, the un-injected mold core 2 or the molded mold core 2 located on the mold base 1 can be pushed by hand to remove the molded mold core 2 from the mold base 1. The un-injected mold core 2 will be placed into the receiving groove 11 to wait for the next injection.

[0021] Based on the above solution, this application achieves a sliding connection between the mold core 2 and the receiving groove 11 by setting a receiving groove 11 on the mold frame 1 and by setting a first back plate 23 on the front mold 21 and a second back plate 24 on the rear mold 22. When the mold is finished, if it is necessary to replace the mold of the Christmas tree leaf, it is only necessary to disassemble and assemble the mold core 2 in the receiving groove 11 to perform injection molding, without replacing the entire mold frame 1, thereby avoiding frequent mold replacement and improving production efficiency. In addition, since the disassembly and assembly of the mold core 2 in the receiving groove 11 is completed by sliding, it is very convenient and labor-saving for workers to operate.

[0022] like Figure 2 and Figure 3 As shown, in order to ensure that the front mold 21 will not fall off the receiving groove 11 when sliding, the first back plate 23 includes a first plate 231 and a first extension 232 provided on one side of the first plate 231. The first plate 231 is provided on the top surface of the front mold 21. The side wall of the receiving groove 11 is provided with a first sliding groove 111, and the first sliding groove 111 and the first extension 232 are adapted to each other. The first extension 232 can be slidably connected to the first sliding groove 111.

[0023] like Figure 2 and Figure 3As shown, in order to further ensure that the front mold 21 will not fall off the receiving groove 11 when sliding, the first back plate 23 includes a plurality of first extensions 232, and the plurality of first extensions 232 are symmetrically arranged on both sides of the first plate 231. The two side walls of the receiving groove 11 are provided with a plurality of first sliding grooves 111, and the plurality of first sliding grooves 111 and the plurality of first extensions 232 are arranged in a one-to-one correspondence.

[0024] like Figure 2 and Figure 3 As shown, in order to ensure that the rear mold 22 will not fall off the receiving groove 11 during sliding, the second back plate 24 includes a second plate 241 and a second extension 242 provided on one side of the second plate 241. The second plate 241 is provided on the bottom surface of the rear mold 22. The side wall of the receiving groove 11 facing the second extension 242 is provided with a flange 112. The top surface of the second extension 242, the side of the second plate 241 facing the flange 112, and the bottom surface of the rear mold 22 together form a second sliding groove 25. The second sliding groove 25 is adapted to the flange 112, and the second back plate 24 is slidably connected to the flange 112 through the second sliding groove 25.

[0025] like Figure 2 and Figure 3 As shown, in order to further ensure that the rear mold 22 will not fall out of the receiving groove 11 during sliding, the second back plate 24 includes a plurality of second extensions 242, and the plurality of second extensions 242 are symmetrically arranged on both sides of the second plate 241. The plurality of second extensions 242, the second plate 241 and the rear mold 22 together form a plurality of second sliding grooves 25. The receiving groove 11 has a plurality of flanges 112, and the plurality of second sliding grooves 25 and the plurality of flanges 112 are arranged in a one-to-one correspondence.

[0026] like Figure 3 As shown, for ease of use, the first back plate 23 and the front mold 21 are connected as one piece, and the second back plate 24 and the rear mold 22 are connected as one piece.

[0027] like Figure 3 As shown, to easily distinguish between the front mold 21 and the rear mold 22, the cross-sectional area of ​​the first back plate 23 in the vertical direction is M, and the cross-sectional area of ​​the second back plate 24 in the vertical direction is N, where M ≠ N. In this embodiment, as... Figure 3 As shown, the cross-sectional area N of the second back plate 24 in the vertical direction is greater than the cross-sectional area M of the first back plate 23 in the vertical direction, so as to better enable injection molding workers to distinguish between the front mold and the rear mold and avoid assembly errors.

[0028] like Figure 1As shown, in order to facilitate use and ensure the quality of injection molding, it also includes an injection molded part 3. The top surface of the mold frame 1 has an injection port, and the injection port is connected to one side of the injection cavity. The injection molded part 3 is disposed at the injection port and is used to input material into the injection cavity.

[0029] In summary, this utility model provides a mold that achieves a sliding connection between the mold core 2 and the receiving groove 11 by setting a receiving groove 11 on the mold frame 1 and by setting a first back plate 23 on the front mold 21 and a second back plate 24 on the rear mold 22. This allows the mold core 2 to be slidably connected to the receiving groove 11 when the mold for the Christmas tree leaf needs to be replaced, which only requires the mold core 2 to be disassembled and assembled in the receiving groove 11, thereby avoiding frequent mold replacements and improving production efficiency. In addition, the sliding method used to disassemble and assemble the mold core 2 in the receiving groove 11 makes it very convenient and labor-saving for workers to operate.
