Each mold core 1 has a rectangular forming hole 11, and the forming holes 11 are connected. The half-cavity surface adjustment component 2 is arranged in the forming hole 11. The half-cavity surface adjustment component 2 between the two mold cores 1 is used to form a workpiece cavity, so that the size of the workpiece cavity and the surface shape of the inner surface of the workpiece cavity can be changed, so that key products of different specifications can be made.

[0032] Reference Figure 1 and Figure 2 Specifically, the half-cavity surface adjustment components 2 include a matching block 21 and a matching driving member 22. The matching block 21 is roughly in the shape of a rectangular parallelepiped. The matching block 21 is slidably arranged in the forming hole 11. A plurality of matching blocks 21 are distributed in the forming hole 11 in a rectangular array. Two adjacent matching blocks 21 are abutted against each other. The side of the matching blocks 21 between the two mold cores 1 that are close to each other will form a part cavity; the matching driving member 22 is connected to the matching block 21. The matching driving member 22 is used to drive the matching block 21 to move along the axial direction of the forming hole 11. The distance between the end face of the matching block 21 and the interface of the mold core 1 can be changed by the matching driving member 22, so that the area between the interfaces of the plurality of matching blocks 21 on each mold core 1 and the forming hole 11 will change, thereby changing the size of the part cavity and the surface shape of the inner surface of the part cavity.

[0033] In addition, in the present embodiment, a pouring channel 12 is provided on the inner wall of the molding hole 11 close to one end, and a plurality of pouring channels 12 are distributed along the axis of the molding hole 11, and a plurality of pouring channels 12 are distributed around the axis of the molding hole 11. This can not only smoothly match parts of different thicknesses, but also realize layered injection molding, thereby also being able to produce two-color plastic parts.

[0034] Reference Figure 1 and Figure 2 In order to allow the mold to have a button product with a bevel structure, the following settings are correspondingly arranged: a bevel supplement component 3 is arranged between the sides of the matching blocks 21 between the two mold cores 1 where they are close to each other. The bevel supplement component 3 will transform the uneven step surfaces between the two adjacent matching blocks 21 into a continuously extended bevel. Specifically, the bevel supplement component 3 includes an adsorption component 31 and a filling block 32. The adsorption component 31 is arranged on the matching block 21, and the filling block 32 is arranged on the end surfaces of the matching blocks 21 between the mold cores 1 where they are close to each other. The filling block 32 is connected to the adsorption component 31, so that a structure with a bevel is formed between the sides of the matching blocks 21 where they are close to each other through the shape of the filling block 32.

[0035] Reference Figure 1 and Figure 2 In order to reduce the equipment cost of the mold, the following settings are correspondingly arranged: the filling block 32 is made of epoxy resin glue, and the filling block 32 is made by the injection molding component 4. The end surfaces of the matching block 21 that are close to each other are coated with an anti-stick coating to facilitate the separation of the filling block 32 from the matching block 21. At the same time, considering the working convenience of the injection molding component 4, the mold core 1 is divided into four core blocks 13 that slide against each other, and the four core blocks 13 enclose a molding hole 11.

[0036] Reference Figure 2 and Figure 3 The glue injection molding component 4 includes an in-and-out slide 41, a winding wheel 42, a supplementary belt 43, a pressing plate 44, a dispensing head 45 and a baffle 46. The in-and-out slide 41 is slidably arranged on the side close to each other between the two mold cores 1. The movement direction of the in-and-out slide 41 is parallel to the boundary surface between the mold cores 1. Multiple in-and-out slides 41 on one mold core 1 are symmetrically arranged relative to the molding hole 11; the winding wheel 42 is rotatably arranged on the in-and-out slide 41, and one winding wheel 42 is matched with one in-and-out slide 41; the supplementary belt 43 is made of silicone, and the two ends of the supplementary belt 43 are respectively connected to the two winding wheels 42, and the supplementary belt 43 is in contact with the side of the matching blocks 21 between the mold cores 1 that are close to each other. The supplementary belt 43 is connected to the adsorption component 31, and the bonding force between the supplementary belt 43 and the filling block 32 is greater than the bonding force between the filling block 32 and the anti-stick coating.

[0037] Reference Figure 2 and Figure 3 The pressing plate 44 abuts against the vertically extending portion of the supplementary belt 43 adjacent to the inclined portion; the glue dispensing head 45 is used to inject epoxy resin glue between the supplementary belt 43 and the matching block 21; the baffle plate 46 is U-shaped, one end of the bend of the baffle plate 46 is connected to the end of the glue dispensing head 45, and the inner side of the bend of the baffle plate 46 is used to seal the space between the supplementary belt 43 and the matching block 21, and the inner side of the baffle plate 46 is also coated with an anti-stick coating.

[0038] Reference Figure 2 and Figure 3 The steps of making the filling block 32 are as follows: first, move one of the core blocks 13 away to reveal an area connected to the forming hole 11; second, move the supplementary belt 43 into the range of the forming hole 11 through the in-and-out slide 41; third, move the matching block 21 upward to abut against the supplementary belt 43; fourth, let the adsorption member 31 adsorb the supplementary belt 43; fifth, let the matching block 21 gradually move away from the interface of the forming hole 11 until different matching blocks 21 are at different predetermined positions; sixth, let the pressing plate 44 abut against the vertical part of the supplementary belt 43 adjacent to the inclined surface to be formed; seventh, keep the pressing plate 44 Abut to maintain the connection between the adsorption part 31 and the non-inclined part of the supplementary belt 43, and reel in the supplementary belt 43 through two reel-ups 42 to allow the supplementary belt 43 to be in an inclined extended state in a predetermined area; eighth, the glue dispensing head 45 moves into the range where the molding hole 11 is located, and at the same time, the baffle plate 46 seals the space between the supplementary belt 43 and the matching block 21; ninth, the glue dispensing head 45 injects epoxy resin glue until the glue solidifies, and the glue dispensing head 45 and the baffle plate 46 leave the range where the molding hole 11 is located; tenth, the mold core is closed to restore the initial structure of the molding hole 11, thereby completing the manufacture of the part cavity with an inclined structure.

[0039] In addition, in this embodiment, during demolding, the supplementary belt 43 may be tensioned so as to provide a force for the workpiece to move away from the matching block 21 through the supplementary belt 43, thereby improving demolding smoothness.

[0040] Reference Figure 2 and Figure 4 , considering that when the inclined surface supplementary component 3 is not needed, in order to maintain the flatness of the end surfaces of the matching block 21 close to each other, the matching structure between the adsorption member 31 and the matching block 21 is as follows: first, the matching block 21 is coaxially provided with an adsorption channel 211, and the ports of the adsorption channel 211 close to each other are in the shape of stepped holes; second, the adsorption member 31 includes an adsorption bracket 311, an adsorption valve block 312 and a self-extending spring 313; the adsorption bracket 311 is arranged in the adsorption channel 211, the adsorption valve block 312 is slidably arranged at the port of the adsorption channel 211, the adsorption valve block 312 cooperates with the part with a smaller inner diameter of the adsorption channel 211, one end of the self-extending spring 313 is connected to the adsorption bracket 311, and the other end is connected to the adsorption valve block 312; when the adsorption member 31 is not working, the adsorption valve block 312 is just flush with the end surface of the matching block 21, thereby maintaining the shape accuracy of the inner surface of the mold cavity of the workpiece without an inclined surface structure.

[0041] In addition, in this embodiment, considering the simplicity of the structure, the matching drive component 22 is a suction cup cylinder structure, and the air path structure of the matching drive component 22 is directly connected to the adsorption channel 211, so that while driving the matching block 21, the structure of the mold can be more compact.

[0042] The implementation principle of a high-precision injection mold with intelligent specification adaptation in an embodiment of the present application is: the distance between the end face of the matching block 21 and the interface between the mold core 1 can be changed by the matching driving component 22, so that the area between the interfaces of multiple matching blocks 21 and the molding hole 11 on each mold core 1 will change, so the size of the part cavity and the surface shape of the inner surface of the part cavity can be changed, so that key products of different specifications can be made.

[0043] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
