Mold structure

The invention relates to a mold structure.

The previous mold structure required different mold holders to be used to adjust the mold when molding different products. The mold base is usually bulky and cumbersome, which requires a lot of time for the mold to be disassembled and assembled.

In view of this, it is necessary to provide a mold structure that can save assembly and disassembly time.

A mold structure includes a male mold base, a female mold base, a male mold core, a female mold core and a fixed block. The female mold base includes a set of first side and second side parallel to each other. The male mold base includes a set of third side and fourth side parallel to each other. The male mold base is provided with a male mold cavity and a first fixing groove. The female mold base is provided with a mother mold cavity and a second fixing groove. The first fixing groove vertically communicates with the third side surface and the fourth side surface of the male mold cavity and the male mold base which are parallel to each other. The second fixing groove vertically communicates with the first side surface and the second side surface of the female mold cavity and the female mold base which are parallel to each other. The male and female mold cores are respectively correspondingly received in the male mold cavity and the female mold cavity. The fixing blocks are respectively inserted into the first fixing groove and the second fixing groove to hold the male and female mold cores fixed in the male and female mold cavities. The male and female mold cores respectively include a molding surface provided with a molding structure, a bottom surface parallel to the molding surface, and a circular side wall perpendicularly connected to the molding surface and the bottom surface, and the circular side wall is parallel to the Central axis of the mother mold The directions respectively extend outwardly from two positioning blocks symmetrically distributed about the central axis of the female mold core. The portion of the forming surface that is connected to the circular side wall is provided with two pressing grooves symmetrically distributed about the axis of the male mold core. The positioning block and the pressing groove are offset from each other. The male mold core and the female mold core have different heights in a direction perpendicular to the molding surface.

Compared with the prior art, the mold structure provided by the present invention respectively defines a male and female mold cavity on the male mold base and the female mold base to place corresponding male and female mold cores, and vertically connects the male mold cavity and the male mold base respectively. A fixing block is inserted into the first fixing groove of the side surface and the second fixing groove of the side of the vertical connecting female mold cavity and the side of the female die seat to fix the male and female mold cores. Therefore, when molding different products, it is only necessary to disassemble the fixing block to replace the corresponding male and female mold cores without replacing the entire male and female mold bases, thereby saving the time for mold disassembly and assembly.

It is closely connected to the female mold base 100a and the male mold base 100b. Because the length of the holding arm 1021 of the fixing block 102 in the direction perpendicular to the connecting base 1020 is larger than the through portion 1043, when the fixing block 102 is inserted into the first fixing groove 104a and the second fixing groove 104b, respectively. The end of the holding arm 1021 is inserted into the second pressing groove 1014b of the male mold core 100b and the first pressing groove 1014a of the female mold core 100a, respectively, to prevent the female mold core 101a. And the male mold 101b falls out of the corresponding mother mold cavity 103a and the male mold cavity 103b.

The male mold base 100b is split by a molding machine. At this time, the first molding surface 1010a of the female mold 101a is flush with the pressing surface 1005a of the female mold base 100a, and the pressing surface of the second molding surface 1005b of the male mold 101b and the male mold base 100b. 1005b stays flush. Since the female mold 101a and the male mold 101b of the mold structure 10 are respectively fixed and assembled in the female mold base 100a and the male mold base 100b in the state of being assembled and assembled, the mother is The accuracy of center positioning of the mold core 101a and the male mold core 101b is greatly improved, and it can be used for mold forming high-precision molds.

The mold structure 10 provided by the present invention respectively defines a male mold cavity 103a and a male mold base 100b on the female mold base 100a to open a male mold cavity 103b for placing the corresponding female mold core 101a and the male mold core 101b, and is opened in the female mold. The fixing block 102 is inserted into the first fixing groove 104a on the opposite sides of the cavity 103a and the second fixing groove 104b on the opposite sides of the male cavity 103b to fix the female die 101a and the male die 101b. Therefore, when molding different products, only the fixing block 102 needs to be disassembled to replace the corresponding female mold 101a and male mold 101b without replacing the whole female mold base 100a and the male mold base 100b, thereby saving the time for mold disassembly and assembly. .

In summary, the present invention has indeed met the requirements of the invention patent, and has filed a patent application according to law. However, the above description is only a preferred embodiment of the present invention, and it is not possible to limit the scope of the patent application of the present invention.
