Description

Technical Field

[0001] The utility model relates to the technical field of molds, in particular to a spliced ​​mold core structure. Background Art

[0002] The mold core refers to the precision part used for the key operation of the center of the mold. The current molds include dynamic molds, static molds and mold cores used for molding product parts. In the existing mold core production process, after the size of the parts is produced according to the needs, the corresponding mold core is made by one-piece molding. However, due to the different sizes of the parts to be produced, if the parts are large, the mold core is molded into the corresponding size according to the needs. At this time, the mold core has a large volume and its stability will be reduced during use. When the mold core is squeezed during injection molding, it is easy to deform, thereby affecting the precision. Therefore, a spliced ​​mold core structure is provided to solve the above problems.

[0019] Please refer to Figure 1-Figure 4 The utility model discloses a spliced ​​mold core structure, comprising: a bottom plate 1, a first side mold core 2, a second side mold core 3, and a top block 4. The upper end of the bottom plate 1 is located at one side of the first side mold core 2 and the second side mold core 3 and is provided with a limiting groove 101. The first side mold core 2 and the second side mold core 3 are both provided with two, and the bottoms of the first side mold core 2 and the second side mold core 3 are both provided with a clamping block 7. The bottom plate 1 is located at one side of the limiting groove 101 and is provided with a guide column 9 for guiding the top block 4. The guide column 9 is provided with four.

[0020] Combination Figure 2 and Figure 4 As shown, the second side mold core 3 is symmetrically provided with first holes 301 at both ends, and the first inner sleeve 302 is sleeved inside the first hole 301. The first inner sleeve 302 cooperates with the positioning rod 603 to effectively avoid the positioning rod 603 from directly contacting the second side mold core 3 and causing wear. A template 5 is arranged on the upper end of the top block 4, and a cover plate 6 is arranged above the template 5. Square holes 601 are symmetrically provided at both ends of the cover plate 6, and a supporting block 602 is connected inside the square hole 601. The supporting block 602 can be used to clamp and limit the template 5 when the cover plate 6 is closed. The supporting block 602 abuts against the side of the clamping template 5, and a positioning rod 603 is connected inside the cover plate 6 on the side facing the first inner sleeve 302. The positioning rod 603 penetrates and slides through the inner wall of the first inner sleeve 302.

[0021] Combination Figure 3 As shown, a second hole 401 is provided on the side of the top block 4 facing the guide column 9, and a second inner sleeve 10 is connected inside the second hole 401. The second inner sleeve 10 cooperates with the guide column 9 to effectively improve the stability of the structure of the top block 4 when it is moved up and down, and improves the accuracy to avoid scratches between the top block 4 and the first side mold core 2 and the second side mold core 3. The second inner sleeve 10 is slidably sleeved on the guide column 9, and the clamping block 7 is fitted inside the limiting groove 101. The first side mold core 2 and the second side mold core 3 are both fixed to the bottom plate 1 by a screw rod, and a top rod 8 is movably connected to the inner wall of the bottom plate 1 close to the guide column 9, and the top rod 8 is fixedly connected to the top block 4 by a screw rod.

[0022] In summary, the utility model, through the splicing and assembly method of the base plate 1 and the two first side mold cores 2 and the two second side mold cores 3, makes the clamping blocks 7 on the first side mold core 2 and the second side mold core 3 aligned and inserted in the limiting groove 101 on the base plate 1, and then a plurality of screw rods are correspondingly passed through the first side mold core 2 and the second side mold core 3 and threadedly connected to the base plate 1. At this time, when the mold core is in use and the cover plate 6 is closed on the first side mold core 2 and the second side mold core 3 to perform injection molding of the product, the spliced ​​first side mold core 2 and the second side mold core 3 and the clamping block 7 cooperate with the limiting groove 101, so that the connection structure can be strengthened, and the first side mold core 2 and the second side mold core 3 can be effectively prevented from being squeezed inside the mold core and causing deformation of the first side mold core 2 and the second side mold core 3.
