The present invention will be specifically described below with reference to the accompanying drawings.

Referring to FIG. 1, a mold 100 provided by the present invention includes a mold base 10, a mold core 20 disposed in the mold base 10, and two mold plates 30 disposed at opposite ends of the mold base 10.

The mold base 10 is a box-shaped structure, and a mold hole 101 extending to the inside of the mold base 10 is disposed on one side of the mold base 10, and the mold core 20 is disposed in the mold cavity 101. The mold base 10 includes a male mold base 11 and a female mold base 12 interconnected with the male mold base 11. The cavity 101 is disposed on one side of the male and female mold bases 11, 12 adjacent to each other, and includes a male mold cavity 1011 located in the male mold base 11 and located in the female mold base 12 The mother mold cavity 1012. The male mold cavity 1011 is adjacent to the female mold One end of the cavity 1012 is formed with two parallel and opposite first sliding grooves 1021. Correspondingly, the female mold cavity 1012 is formed with two parallel and opposite second sliding ends near one end of the male mold cavity 1011. In the slot 1022, the first sliding slot 1021 and the second sliding slot 1022 cooperate with each other to form two integral and opposite sliding slots 102 (see FIG. 3).

A plurality of accommodating holes 103 are defined in the two parallel opposing side walls of the male mold cavity 1011, and a plurality of accommodating holes 103 are respectively defined in the two parallel opposing side walls of the female die cavity 1012. The accommodating holes 103 on each side wall are perpendicular to the corresponding side wall surfaces. In this embodiment, the total number of the receiving holes 103 is eight. Of course, the number thereof may also be changed according to actual conditions. Each of the accommodating holes 103 is provided with a positioning pin 104. One end of the locating pin 104 protrudes from the accommodating hole 103, and one end of the accommodating hole 103 is elastically compressed to the The hole 103 is accommodated. Specifically, referring to FIG. 2 , each of the positioning pins 104 includes a sleeve 1041 and a ball 1042 elastically disposed in the sleeve 1041 and partially protruding from one end of the sleeve 1401 . An interference fit between the sleeve 1041 and the receiving hole 103 is provided, and one end of the ball 1042 is disposed to protrude from a sidewall of the cavity 101 corresponding to the receiving hole 103.

The mold core 20 includes a male mold core 21 and a female mold core 22 matched with the male mold core 21, and the male mold core 21 is disposed in the male mold cavity 1011. The master mold core 22 is disposed in the master mold cavity 1012. The joint of the male mold core 21 and the female mold core 22 forms two sliders 201 corresponding to the sliding grooves 102. The slider 201 can slide in the sliding slot 102 respectively. The mold core 20 is received in the mold cavity 101 or taken out from the mold cavity 101 by sliding of the slider 201 along the sliding groove 102. The male mold core 21 and the female mold core 22 are perpendicularly extended with two mutually parallel blocks 211, and the female mold core 22 is opposite to the male mold core 21 Two open corresponding to the block 211 and mutual Parallel card slot 221. The two clamping blocks 211 are respectively disposed in the two card slots 221 to position the male mold core 21 and the female mold core 22 to each other. A positioning hole 202 corresponding to the positioning pin 104 is respectively disposed on a side surface of the male mold core 21 and the female mold core 22, and the positioning pin 104 is disposed with one end of the ball 1042 extending respectively. The positioning hole 202 is inside.

The male mold core 21 further defines a pull ring hole 203. The pull ring hole 203 is a threaded hole formed in a side of the male mold core 21 exposed from the mold base. A pull ring (not shown) can be screwed into the pull ring hole 203 for facilitating removal of the mold core 20 from the cavity 101. In the embodiment, the tab hole 203 is opened in the side surface of the male mold core 21 exposed from the mold base, and of course, it may be opened in the side surface of the female mold core 22 .

The template 30 is used for fixing the die holder 10, and includes a male die template 31 on a side of the male die holder 11 and a female die template 32 on a side of the female die holder 12 The male mold base 11 and the female mold base 12 are interposed between the male mold template 31 and the female mold template 32.

Referring to FIG. 3 and FIG. 4, when the mold 100 is to be changed, the original mold core (not shown) is taken out from the side of the mold base 10 from which the mold cavity 101 is opened, and the mold core 20 to be replaced is replaced. The male mold core 21 and the female mold core 22 are engaged with each other, and the mold core 20 after the positioning is completed can be pushed along the sliding groove 102 from the side of the mold base 10 provided with the mold 101. Into the cavity 101, the positioning pins 104 are respectively engaged in the corresponding positioning holes 202, and the positioning of the mold core 20 is completed, and the mold 100 can be used for molding the product.

The mold is opened on the side of the mold base, and the mold core can be taken into the mold cavity from the side of the mold base of the mold cavity and taken out from the mold base, thereby avoiding the disassembly and assembly of the mold base. Loading, saving the process and time of mold change, improving production efficiency, and the positioning of the mold of the mold is relatively simple and fast.
