[0032] Example 1: Please see Figures 1-4 , Figure 6 and Figure 7 A mold with a quick-release mold core includes an upper template 10, an upper mold core 20, a lower mold core 30, and a lower template 40 arranged sequentially from top to bottom.

[0033] The lower surface of the upper template 10 is provided with a first mounting plane 11, and the upper mold core 20 is detachably mounted on the first mounting plane 11 by fasteners. The upper surface of the lower template 40 is provided with a second mounting plane 41, and the lower mold core 30 is detachably mounted on the second mounting plane 41 by fasteners. More specifically, the upper template 10 has a first fixing hole 14, and the upper mold core 20 has a first through hole 24 that mates with the first fixing hole 14.

The second positioning structure includes a second positioning element 42 installed on the second mounting plane 41 by fasteners and a second positioning groove 31 recessed on the lower surface of the lower mold core 30. The second positioning element 42 cooperates with the second positioning groove 31.

[0035] As described above, the mold with quick-release mold core provided by this utility model achieves a mold core-less frame design for the upper template 10 and lower template 40 through the cooperation of the first mounting plane 11 with the upper mold core 20 and the second mounting plane 41 with the lower mold core 30. The mold core-less frame design avoids the limitation that the upper template 10 and lower template 40 can only install a single specification of upper mold core 20 and lower mold core 30, respectively. This allows the mold with quick-release mold core to be compatible with mold cores of different specifications, enabling the production of products of different specifications and reducing production costs. By setting the first positioning structure and the second positioning structure, the structures of the first positioning structure and the second positioning structure are simple, and the upper mold core 20 and lower mold core 30 are easily positioned on the upper template 10 and lower template 40, respectively. Furthermore, through the cooperation of the upper mold core 20 and lower mold core 30 with fasteners, the upper mold core 20 and lower mold core 30 are easy to install, thus achieving good convenience in the assembly and disassembly of the mold core of the mold with quick-release mold core.

[0036] Furthermore, the first positioning groove 21 is disposed on the upper edge of the upper mold core 20 and connects with the side wall of the upper mold core 20. The first positioning groove 21 cooperates with the first positioning member 12, with one end of the first positioning member 12 extending outward from the side wall of the upper mold core 20. This arrangement allows the first positioning member 12 to be exposed on the side wall of the upper mold core 20, facilitating observation and alignment by the operator when positioning the upper mold core 20 to ensure that the first positioning groove 21 is aligned with the first positioning member 12. In this embodiment, a first positioning groove 21 is provided on each of the four edges of the upper surface of the upper mold core 20.

[0037] The second positioning groove 31 is disposed on the lower edge of the lower mold core 30 and connects with the side wall of the lower mold core 30. The second positioning groove 31 cooperates with the second positioning member 42, with one end of the second positioning member 42 extending outward from the side wall of the lower mold core 30. This arrangement allows the second positioning member 42 to be exposed on the side wall of the lower mold core 30, facilitating observation and alignment by the operator when positioning the lower mold core 30 to ensure that the second positioning groove 31 is aligned with the second positioning member 42. In this embodiment, a second positioning groove 31 is provided on each of the four edges of the lower surface of the lower mold core 30.

[0038] Please see Figure 3 , Figure 8 and Figure 9 The first mounting plane 11 is recessed with a first mounting groove 13 for mounting the first positioning member 12. The first positioning member 12 is detachably mounted in the first mounting groove 13, so that the first positioning member 12 is mounted on the upper template 10. The second mounting plane 41 is recessed with a second mounting groove 43 for mounting the second positioning member 42. The second positioning member 42 is detachably mounted in the second mounting groove 43, so that the second positioning member 42 is mounted on the lower template 40.

[0039] Furthermore, the first mounting groove 13 has multiple first adjustment holes 131 arranged in a straight line evenly. The first positioning member 12 has at least one first mounting hole 121 that mates with the first adjustment hole 131. The number of first adjustment holes 131 is greater than the number of first mounting holes 121. The first positioning member 12 is installed in the first mounting groove 13 by fasteners passing through the first mounting holes 121 and screwed into the first adjustment holes 131. In addition, through the cooperation of the first mounting holes 121 and the first adjustment holes 131, the first positioning member 12 can be installed closer to the inside or closer to the outside along the length direction of the first mounting groove 13, so as to adjust the position of the first positioning member 12 to position the upper mold core 20 of different specifications. More specifically, when the first positioning member 12 is installed closer to the inside along the length direction of the first mounting groove 13, the upper template 10 can be adapted to the upper mold core 20 with a smaller specification; when the first positioning member 12 is installed closer to the outside along the length direction of the first mounting groove 13, the upper template 10 can be adapted to the upper mold core 20 with a larger specification.

[0040] The second mounting groove 43 has multiple second adjustment holes 431 arranged in a straight line evenly. The second positioning member 42 has at least one second mounting hole 421 that mates with the second adjustment hole 431. The number of second adjustment holes 431 is greater than the number of second mounting holes 421. The second positioning member 42 is installed in the second mounting groove 43 by fasteners passing through the second mounting holes 421 and screwed into the second adjustment holes 431. In addition, by cooperating with the second adjustment holes 431 and the second mounting holes 421, the second positioning member 42 can be installed closer to the inside or closer to the outside along the length direction of the second mounting groove 43, so as to adjust the position of the second positioning member 42 to position the lower mold core 30 of different specifications. More specifically, when the second positioning member 42 is installed closer to the inside along the length direction of the second mounting groove 43, the lower mold plate 40 can be adapted to the lower mold core 30 with a smaller specification; when the second positioning member 42 is installed closer to the outside along the length direction of the second mounting groove 43, the lower mold plate 40 can be adapted to the lower mold core 30 with a larger specification.

[0041] Furthermore, the first positioning member 12 is cylindrical and has a first mounting hole 121. In this embodiment, the first mounting groove 13 has three first adjustment holes 131, which can cooperate with any one of the first adjustment holes 131 to achieve three-stage adjustment of the position of the first positioning member 12. The second positioning member 42 is cylindrical and has a second mounting hole 421. The second mounting groove 43 has three second adjustment holes 431, which can cooperate with any one of the second adjustment holes 431 to achieve three-stage adjustment of the position of the second positioning member 42.

[0042] Please see Figures 4-7 A third positioning structure is provided between the upper mold core 20 and the lower mold core 30 for positioning. Through the third positioning structure, the upper mold core 20 and the lower mold core 30 can be tightly engaged when the mold is closed, so as to prevent deviation in the fit between the upper mold core 20 and the lower mold core 30, thereby ensuring the quality of the product.

[0043] More specifically, the third positioning structure includes a mating protrusion 32 protruding from the upper surface of the lower mold core 30 and a mating groove 22 recessed from the lower surface of the upper mold core 20, wherein the mating protrusion 32 and the mating groove 22 mate with each other. In this embodiment, a mating protrusion 32 is provided at each of the four corners of the upper surface of the lower mold core 30, and a mating groove 22 is provided at each of the four corners of the lower surface of the upper mold core 20.

[0044] When the mold with quick-release mold core is closed, the mating protrusion 32 and the mating groove 22 fit together, and the upper mold core 20 and the lower mold core 30 together form a cavity for molding the product.

[0045] Furthermore, a first chamfer structure 33 is provided on the upper edge of the mating protrusion 32, and a second chamfer structure 23 is provided at the corner of the mating groove 22 and the lower surface of the upper mold core 20. During the mold closing process of the upper mold core 20 and the lower mold core 30, the cooperation of the first chamfer structure 33 and the second chamfer structure 23 can prevent the mating protrusion 32 from directly hitting the corner of the mating groove 22 and the lower surface of the upper mold core 20, thus avoiding damage to the mold and extending the mold life. At the same time, it makes the operation process of the upper mold core 20 and the lower mold core 30 approaching each other smoother.

[0046] Example 2: A mold with a quick-release mold core, the structure of which is similar to that of the mold with a quick-release mold core in Example 1, the difference being: Please see Figure 10 and Figure 11 The first positioning member 12 is block-shaped and has at least two first mounting holes 121. The distance between two adjacent first mounting holes 121 is equal to the distance between two adjacent first adjusting holes 131. By providing at least two first mounting holes 121, the first positioning member 12 can be prevented from rotating or shifting within the first mounting groove 13, thus affecting the positioning effect of the upper mold core 20. The second positioning member 42 is block-shaped and has at least two second mounting holes 421. The distance between two adjacent second mounting holes 421 is equal to the distance between two adjacent second adjusting holes 431. By providing at least two second mounting holes 421, the second positioning member 42 can be prevented from rotating or shifting within the second mounting groove 43, thus affecting the positioning effect of the lower mold core 30.

[0047] In this embodiment, four first adjustment holes 131 are provided in the first mounting groove 13, and two first mounting holes 121 are provided in the first positioning member 12. The two first mounting holes 121 can cooperate with any two adjacent second adjustment holes 431 to realize three-stage adjustment of the position of the second positioning member 42; four second adjustment holes 431 are provided in the second mounting groove 43, and two second mounting holes 421 are provided in the second positioning member 42. The two second mounting holes 421 can cooperate with any two adjacent second adjustment holes 431 to realize three-stage adjustment of the position of the second positioning member 42.
