Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0026] In the description of this application, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing this application 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 application. 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 indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0027] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0028] like Figures 1 to 5As shown, this application provides a mold that facilitates the cleaning of lubricating oil stains, including: a mold body 100, comprising a rear mold base plate 10, a front mold base plate 20, a front mold base 30, a square iron 50, a rear mold base 60, an ejector pin fixing plate 70, an ejector pin auxiliary plate 80, an ejector pin body 90, a guide rod 1000, a return spring 1010, and a disassembly hole 1020; a main channel 40 is provided in the middle of the front mold base plate 20; a support base plate 1030 is provided in the middle of the ejector pin fixing plate 70; and a disassembly assembly 1. 040, located in the middle of the support base plate 1030 and the ejector pin fixing plate 70, includes a positioning groove 1041 in the middle of the ejector pin fixing plate 70, a positioning block 1042 on the outer side of the support base plate 1030, and a sliding groove 1043 and an auxiliary groove 1048 in the middle of the positioning block 1042. A limiting groove 1044 is provided on the inner side of the positioning groove 1041, a limiting block 1045 is provided in the middle of the sliding groove 1043, and a support spring 1049 is provided on one side of the limiting block 1045.

[0029] After adopting the above technical solution, since the disassembly component 1040 is located in the middle of the support base plate 1030 and the ejector pin fixing plate 70, when the ejector pin body 90 needs to be disassembled, the support base plate 1030 can be disassembled through the disassembly hole 1020 and the disassembly component 1040, thereby releasing the support for the ejector pin body 90, which facilitates the quick disassembly of the ejector pin body 90. This can solve the problem that in the existing ejector pin disassembly and cleaning process, it is necessary to remove the pressure plate screws, ejector pin fixing plate, return spring and other related components in sequence, which takes a long time for a single disassembly, has low efficiency and affects the subsequent use of the mold.

[0030] It should be noted that during the disassembly of the ejector body 90, the limiting block 1045 is pulled by the hand slot 1046, causing the limiting block 1045 to move along the inner side of the slide groove 1043 and the limiting groove 1044. At the same time, the auxiliary block 1047 slides along the inner side of the auxiliary groove 1048, and the support spring 1049 is compressed until the compression trajectory of the support spring 1049 reaches its end. At this time, the limiting block 1045 is disengaged from the inside of the limiting groove 1044. Similarly, the other set of limiting blocks 1045 is moved to release the positioning groove 1041 from the positioning block 1042. The support base plate 1030 is moved outward, so that the positioning block 1042 moves along the inside of the positioning groove 1041. Finally, it is disassembled through the disassembly hole 1020, so that the ejector body 90 can be disassembled without disassembling the mold piece by piece, which facilitates the subsequent cleaning of lubricating oil stains.

[0031] In an alternative embodiment, the front mold base plate 20 and the front mold frame 30 are connected by bolts, and the main channel 40 passes through the middle of the front mold base plate 20 and the front mold frame 30, so that the article can be injection molded into the middle of the rear mold frame 60 and the front mold frame 30, and formed by installing the front and rear mold cores.

[0032] In one optional embodiment, the square irons 50 are arranged in two sets symmetrically. The rear mold frame 60 is connected to the square irons 50 by bolts, and the ejector pin fixing plate 70 is connected to the ejector pin auxiliary plate 80 by bolts, which can drive the ejector pin body 90 to perform ejection operation. The ejector pin auxiliary plate 80 and the rear mold frame 60 are both provided with ejector pin holes that are adapted to the ejector pin body 90 in the middle. When the ejector pin body 90 ejects material, the ejector pin fixing plate 70 is moved by an external hydraulic mechanism, which further drives the ejector pin auxiliary plate 80 and the ejector pin body 90 to move along the ejector pin groove, thereby completing the ejection operation.

[0033] In one optional embodiment, the guide rods 1000 are arranged in four groups in an array. The return spring 1010 is located outside the guide rods 1000, and the two ends of the return spring 1010 are in contact with the ejector plate 80 and the rear mold frame 60, respectively. During the ejection operation of the ejector plate 80 and the ejector fixing plate 70, the return spring 1010 is compressed, so that after the external force is withdrawn, the ejector fixing plate 70, the ejector plate 80 and the ejector body 90 are reset.

[0034] In an optional embodiment, the disassembly hole 1020 penetrates the middle of the rear mold base plate 10, and the ejector pin fixing plate 70 has an adapter hole in the middle, which is adapted to the support base plate 1030. The support base plate 1030 is in contact with the ejector pin body 90, which can support the ejector pin body 90 and facilitate the ejection operation of the ejector pin body 90. After the support base plate 1030 is disassembled, the ejector pin body 90 can be disassembled and cleaned of oil stains.

[0035] In an optional embodiment, the positioning groove 1041 is connected to the adapter hole, the positioning block 1042 is fixedly connected to the support base plate 1030, and the positioning block 1042 is adapted to the positioning groove 1041, so that the support base plate 1030 can be positioned, and the positioning groove 1041 and the positioning block 1042 can be adapted.

[0036] In an optional embodiment, the slide groove 1043 is connected to the auxiliary groove 1048, the limiting groove 1044 has a rectangular structure, the limiting block 1045 is adapted to the limiting groove 1044, and the limiting block 1045 has an "L" shaped structure, which facilitates the insertion of the limiting block 1045 into the limiting groove 1044 to limit the positioning block 1042 and the positioning groove 1041 and prevent them from separating.

[0037] In an optional embodiment, a hand-held groove 1046 is provided on one side of the limiting block 1045, and the hand-held groove 1046 is a cylindrical structure. An auxiliary block 1047 adapted to the auxiliary groove 1048 is fixedly connected to the bottom of the limiting block 1045. The two ends of the support spring 1049 are respectively connected to the limiting block 1045 and the slide groove 1043. During the movement of the limiting block 1045, the auxiliary block 1047 slides along the auxiliary groove 1048 to ensure stability during the movement. At the same time, the support spring 1049 can store force after being compressed by the limiting block 1045. When the limiting block 1045 is aligned with the limiting groove 1044, the elastic potential energy of the support spring 1049 can make the limiting block 1045 quickly insert into the interior of the limiting groove 1044.
