The mold for placing an insert includes an upper mold 10, a lower mold 20 and at least one expansion groove assembly 30, wherein the upper mold 10 and the lower mold 20 are correspondingly arranged to facilitate mold closing.
[0026] like Figure 3 As shown, the upper mold 10 includes an upper mold body 11 and at least one upper mold core 12, wherein the upper mold body 11 can be controlled to move up and down, the upper mold core 12 is installed at the bottom of the upper mold body 11, and the upper mold core 12 can move synchronously with the upper mold body 11.
[0027] like Figures 3 to 5As shown, the lower mold 20 includes a lower mold body 21 and at least one lower mold core 22, wherein the lower mold core 22 is installed on the lower mold body 21. The upper mold body 11 is installed on the lower mold body 21 in a moldable manner, and each lower mold core 22 corresponds to the position of one upper mold core 12, so that after the upper mold body 11 and the lower mold body 21 are molded together, the upper mold core 12 is crimped to the lower mold core 22.
[0028] The lower mold core 22 includes a lower mold core body 221, at least one central lower mold core 222 and at least one side lower mold core 223, wherein the lower mold core body 221 is fixed on the lower mold body 21.

At least one upper mold groove 1201 is formed at the bottom of the upper mold core 12. When the upper mold core 12 is pressed on the lower mold core 22, each upper mold groove 1201 corresponds to one lower mold groove 2201 and together form a die space for injection of rubber for molding.
[0029] The upper mold 10 forms at least one glue injection channel 101, and the glue injection channel 101 is connected to the die space, so that the glue can enter the die space through the glue injection channel 101, thereby forming a part.
[0030] It is worth mentioning that before making the parts, the operator needs to place an insert 90 in each of the lower mold grooves 2201 before the mold can be closed and glue injected.
[0031] At least one end of the lower mold core 22 is provided with a slot expansion assembly 30, and the slot expansion assembly 30 is configured to drive the central lower mold core 222 and the side lower mold core 223 to separate.

After the insert 90 is carried by the lower mold core body 221 and the distance between the central lower mold core 222 and the side lower mold core 223 is reduced by adjustment of the slot expansion assembly 30, the insert 90 is retained in the corresponding lower mold slot 2201.
[0032] Preferably, at least one end of the central lower mold core 222 forms a first driving portion 2221. At least one end of the side lower mold core 223 forms a second driving portion 2231. The slot expansion assembly 30 includes at least one moving member 31, and the first driving portion 2221 and the second driving portion 2231 are arbitrarily mounted on the moving member 31, and can be driven by the moving member 31 to increase the distance between the first driving portion 2221 and the second driving portion 2231, thereby expanding the distance between the central lower mold core 222 and the side lower mold core 223, which is convenient for the operator to place the insert 90.
[0033] In a preferred embodiment, the moving member 31 is configured to be able to move up and down, and the number of the moving member 31 is implemented as one. The moving member 31 forms at least one side moving groove 3101 corresponding to the second driving portion 2231, and in the lateral direction, the length of the side moving groove 3101 is greater than the length of the second driving portion 2231, so that the second driving portion 2231 can move laterally in the side moving groove 3101. The slot expansion assembly 30 also includes a guide member 32, which is fixed to the lower mold body 21 and is located on a side of the moving member 31 close to the lower mold core 22, and the guide member 32 forms at least one side guide groove 3201 corresponding to the side lower mold core 223, and the second driving portion 2231 of the side lower mold core 223 passes through the side guide groove 3201 and remains plugged into the side moving groove 3101.

The moving member 31 is drivably connected to the second driving portion 2231 of the side lower mold core 223.
[0035] Specifically, when the side lower mold core 223 is moved upward by being driven by the moving part 31, since the side guide groove 3201 extends upward at an angle, the second driving part 2231 will move laterally in the side moving groove 3101, thereby expanding the distance between the center lower mold core 222 and the side lower mold core 223, making it easier for the operator to place the insert 90. After placing the insert 90, the moving part 31 moves downward to drive the center lower mold core 222 and the side lower mold core 223 to reset, thereby clamping the insert 90.
[0036] Preferably, the first driving portion 2221 formed at one end of the central lower mold core 222 is on the same side as the second driving portion 2231. The guide member 32 forms at least one central guide groove 3202 corresponding to the central lower mold core 222, and the central guide groove 3202 extends vertically upward, and the vertical length is greater than the vertical moving distance of the moving member 31. The moving member 31 is drivably connected to the first driving portion 2221 and the second driving portion 2231, so that the central lower mold core 222 and the side lower mold core 223 are driven to move upward at the same time, thereby making it easier for the operator to place the insert 90.
[0037] Preferably, the number of the central lower mold cores 222 is implemented as multiple, and each central lower mold core 222 is provided with a side lower mold core 223 on both opposite sides, so that when the central lower mold core 222 and the side lower mold core 223 are close to each other, more number of lower mold grooves 2201 are formed, thereby forming more parts at one time. It is understandable that a sufficient distance is set between two adjacent central lower mold cores 222 to avoid interference between the two side lower mold cores 223 located between the two adjacent central lower mold cores 222 when moving after the side lower mold cores 223 are provided on both sides of the central lower mold core 222.
[0038] Preferably, the number of the slot expansion assemblies 30 is two. The moving parts 31 of the two slot expansion assemblies 30 are respectively located on both sides of the lower mold core 22, and the guide parts 32 of the two slot expansion assemblies 30 are both fixed to the lower mold body 21 and are respectively located on one side of the two moving parts 31 close to the lower mold core 22. Both ends of the central lower mold core 222 form the first driving part 2221, and both ends of the side lower mold core 223 form the second driving part 2231, so that the central lower mold core 222 and the side lower mold core 223 are driven by the two moving parts 31 to move at the same time, so as to be separated as a whole.
[0039] In another embodiment, the moving member 31 is implemented as a cylinder. The number of the moving members 31 of each slot expansion assembly 30 is set to be the same as the sum of the number of the first driving part 2221 and the second driving part 2231 on the same side, each of the first driving part 2221 and the second driving part 2231 is connected to one moving member 31, and the second driving part 2231 and the first driving part 2221 can be driven by the corresponding moving member 31 to move away from each other, thereby expanding the distance between the central lower mold core 222 and the side lower mold core 223, so as to facilitate the placement of the insert 90.
[0040] Preferably, if Figure 2 and Figure 4 As shown, at least one lower glue groove 2202 is formed on the upper surface of the lower mold core 22, and each of the lower glue grooves 2202 is connected to at least two of the lower model grooves 2201. When the upper mold core 12 and the lower mold core 22 are molded, each of the glue injection channels 101 is connected to at least one of the lower glue grooves 2202, so that the injected glue flows from the glue injection channel 101 into the lower glue groove 2202 and then into at least two of the lower model grooves 2201, so as to quickly inject glue while reducing the number requirement of the glue injection channels 101, thereby alleviating the difficulty of making the upper mold 10.
[0041] More preferably, if Figure 3 As shown, at least one upper glue groove 1202 is formed on the bottom surface of the upper mold core 12, and the upper glue groove 1202 is connected to at least two of the upper mold grooves 1201, and the upper glue groove 1202 corresponds to the lower glue groove 2202, so that when the upper mold 10 and the lower mold 20 are closed, the upper glue groove 1202 and the lower glue groove 2202 form a channel, thereby accelerating the flow of glue into the molding space, and then being injection molded into parts.
[0042] Preferably, the upper mold core 12 forms at least one positioning column 121, the lower mold core 22 forms at least one positioning hole 2203, and each positioning hole 2203 corresponds to and is adapted to one positioning column 121, so that when the upper mold 10 is pressed down, each positioning column 121 penetrates into one positioning hole 2203, thereby avoiding misalignment of the upper mold core 12 and the lower mold core 22, which may cause the molded parts to be unqualified.
[0043] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are only examples and do not limit the present invention. The advantages of the present invention have been fully and effectively achieved.
