It can be understood that the opening of the second limiting groove 112 faces the slide 120, the second limiting groove 112 is communicated with the mounting hole 111, and the second limiting groove 112 is communicated with the first limiting groove 121. The insert 200 is inserted into the mounting hole 111, and the limiting flange 210 on the rear of the insert 200 is arranged in the second limiting groove 112, and the limiting flange 210 abuts against the bottom wall of the second limiting groove 112. The bottom wall of the second limiting groove 112 limits the limiting flange 210, that is, the bottom wall of the second limiting groove 112 limits the insert 200, and prevents the insert 200 from moving away from the slide seat 120 during the molding process. In other words, the limiting block 300 and the bottom wall of the second limiting groove 112 clamp and fix the flange on the rear of the insert 200, and the limiting block 300 and the bottom wall of the second limiting groove 112 can prevent the insert 200 from shaking or moving during the molding process, that is, prevent the insert 200 from moving forward or backward, which is conducive to improving the qualified rate of the product.

It can be understood that the avoidance hole 122, the first limiting groove 121, the second limiting groove 112 and the mounting hole 111 are connected in sequence, so that the avoidance hole 122, the first limiting groove 121, the second limiting groove 112 and the mounting hole 111 are connected to each other. When the insert 200 needs to be installed, the operator only needs to put the insert 200 and the limiting flange 210 on the tail of the insert 200 into the avoidance hole 122 on the slide 120, and then use a tool to push the insert 200, so that the insert 200 passes through the avoidance hole 122, the first limiting groove 121 and the second limiting groove 112 in sequence to enter the installation hole 111, and the limiting flange 210 at the tail of the insert 200 passes through the avoidance hole 122 and the first limiting groove 121 in sequence to enter the second limiting groove 112. Then the operator puts the limiting block 300 into the first limiting groove 121, and installs the limiting block 300 on the bottom wall of the first limiting groove 121, so that the limiting block 300 abuts against the limiting flange 210 at the tail of the insert 200, and the limiting flange 210 abuts against the bottom wall of the second limiting groove 112, and the insert 200 can be quickly installed.
[0048] When the insert 200 needs to be removed from the mounting portion 110, the operator can first remove the limiting block 300 from the bottom wall of the first limiting groove 121 and take out the limiting block 300, and then sequentially pass the insert 200 through the mounting hole 111, the second limiting groove 112, the first limiting groove 121 and the mounting hole 111, so that the insert 200 is taken out to complete the rapid removal of the insert 200. It can be understood that the mold structure of the embodiment of the utility model can realize the rapid installation and rapid removal of the insert 200, which improves the convenience of the operator to replace the insert 200.
[0049] refer to Figure 5 and Figure 8The mold structure also includes a cooling pipe 230. A cooling channel 220 is provided on the insert 200. One end of the cooling pipe 230 passes through the avoidance hole 122, the first limiting groove 121 and the second limiting groove 112 and extends into the cooling channel 220. The cooling pipe 230 is used to reduce the temperature of the insert 200. It can be understood that the cooling pipe 230 extends into the cooling channel 220 on the insert 200, so that the cooling pipe 230 can reduce the temperature of the insert 200, improve the cooling efficiency of the insert 200, make the product shrink evenly, reduce the risk of product deformation, warping or internal stress, and help improve the qualified rate of the product. Specifically, the mold structure also includes a water tank and a delivery pump. The water tank is used to store water or coolant. The cooling pipe 230 is connected to the water tank through the delivery pump. The delivery pump is used to deliver the water or coolant in the water tank into the cooling pipe 230, thereby reducing the temperature of the insert 200. The delivery pump can form a circulating waterway between the water tank and the cooling pipe 230. As an embodiment of the present utility model, a pipe penetration hole is opened on the limit block 300, and the pipe penetration hole is used for the cooling pipe 230 to penetrate.
[0050] refer to Figure 5 and Figure 6 , the avoidance hole 122 is a first positioning hole, and the longitudinal section shape of the first positioning hole is the same as the longitudinal section shape of the limiting flange 210. It can be understood that the longitudinal section shape of the first positioning hole is the same as the longitudinal section shape of the limiting flange 210, so that the inner wall of the first positioning hole can play a positioning role for the limiting flange 210, preventing the insert 200 from rotating around its own axis during the installation of the insert 200 by the operator, so that the operator can accurately install the insert 200 in the installation hole 111 of the installation part 110.
[0051] refer to Figure 5 and Figure 7 , the mounting hole 111 is a second positioning hole, and the longitudinal section shape of the second positioning hole is the same as the longitudinal section shape of the insert 200. It can be understood that the longitudinal section shape of the second positioning hole is the same as the longitudinal section shape of the insert 200, so that the inner wall of the second positioning hole can play a positioning role for the insert 200, so that the operator can quickly and accurately install the insert 200 in the second positioning hole of the mounting part 110. On the other hand, the inner wall of the second positioning hole also plays a limiting role for the insert 200, preventing the insert 200 from rotating around its own axis during the molding process, which is conducive to improving the qualified rate of the product.
[0052] It should be explained that, in the present utility model, the longitudinal section refers to a section parallel to the up-down direction and perpendicular to the front-back direction.
[0053] refer to Figure 5 and Fig.10The mold structure also includes a first bolt, a first threaded hole is provided on the bottom wall of the first limiting groove 121, a through hole 310 is provided on the limiting block 300, the first bolt is passed through the through hole 310 and is threadedly connected with the inner wall of the first threaded hole, and the nut of the first bolt can press against the limiting block 300 so that the limiting block 300 is fixed to the bottom wall of the first limiting groove 121. It can be understood that when the limiting block 300 needs to be installed in the first limiting groove 121, the operator can first put the limiting block 300 into the first limiting groove 121, and then put the first bolt into the through hole 310 and tighten the first bolt. The first bolt is threadedly connected with the inner wall of the first threaded hole on the bottom wall of the first limiting groove 121, and the nut of the first bolt presses against the limiting block 300, so that the limiting block 300 can be fixed to the bottom wall of the first limiting groove 121. When the limiting block 300 needs to be disassembled, it is only necessary to loosen the first bolt.
[0054] As an embodiment of the utility model, the mold structure also includes an elastic gasket, and the nut of the first bolt is pressed against the limit block 300 through the elastic gasket. It can be understood that the elastic gasket can provide sufficient pressure for the first bolt, so that the friction between the first bolt and the inner wall of the first threaded hole is increased, thereby preventing the first bolt from loosening during long-term molding processing. It should be explained that in the utility model, assuming that the first bolt is loose, since the limit block 300 is in contact with the side wall of the first limit groove 121, the limit block 300 can also always support the tail of the insert 200, that is, when the first bolt is loose, the limit block 300 can also ensure that the insert 200 does not retreat.
[0055] As an embodiment of the utility model, two through holes 310 are provided on the limit block 300, two first threaded holes are provided on the bottom wall of the first limit groove 121, and there are two first bolts and two elastic gaskets.
