[0040] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the invention or its application or use.

[0041] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0042] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0043] like Figure 1-6 As shown, the first embodiment of this utility model provides an injection mold 1, which includes two mold units 11 that are close to or far apart from each other in a predetermined direction. The predetermined direction is the conventional mold closing / opening direction of two mold units 11 in the injection molding field. The mold unit 11 includes a mold frame 13 and a mold core 12. The mold frame 13 of one mold unit 11 has a recessed mounting cavity 14 on the end face facing the other mold unit 11, and the corresponding mold core 12 is detachably assembled in the mounting cavity 14.

[0044] like Figure 2 As shown, in this embodiment, each mold unit 11 has a recessed mounting cavity 14 on the end face of the mold frame 13 facing another mold unit 11, and the corresponding mold core 12 is detachably assembled in the mounting cavity 14, so that each mold unit 11 is a detachable structure.

[0045] The mold core 12 is assembled into the corresponding mounting cavity 14 along the predetermined direction, and a locking mechanism for fixing the mold core 12 in the mounting cavity 14 is provided between at least one outer wall of the mold core 12 in the predetermined direction and the corresponding inner wall of the mounting cavity 14. Figure 2-5 As shown, in this embodiment, preferably, the locking mechanism is provided between the two adjacent outer sidewalls of the mold core 12 in a predetermined direction and the inner sidewall corresponding to the mounting cavity 14.

The pressure block 16 is installed between the outer side wall of the mold core 12 and the inner side wall of the mounting cavity 14, and squeezes the two to fix the mold core 12 in the mounting cavity 14. The mounting cavity 14 can be configured to adapt the shape of the mold core 12 and the pressure block 16 to minimize the gap between the three.

[0047] Furthermore, in order to improve the extrusion effect and facilitate installation, the pressure block 16 is wedge-shaped in a predetermined direction, so as to facilitate the insertion of the pressure block 16 between the outer wall of the mold core 12 and the corresponding inner wall of the mounting cavity 14.

[0048] Furthermore, in order to fix the pressure block 16 simply and efficiently, a bolt extending in a predetermined direction, namely a fixing bolt 17, is installed inside the pressure block 16. The fixing bolt 17 is connected to the bottom side wall of the mounting cavity 14 to realize the installation of the pressure block 16.

[0049] Assembly process reference for mold unit 11 Figure 2-4 Based on the above structural description, the assembly process is already clear, so it will not be described in words here.

[0050] When replacing this injection mold 1, only the mold core 12 needs to be replaced, without having to disassemble and replace the entire injection mold 1. This makes disassembly and assembly more convenient, more efficient, and safer to operate.

[0051] like Figure 1 As shown, this embodiment also relates to an injection molding assembly, including two mold bases 2 and an injection mold 1 as described above. Two mold units 11 of the injection mold 1 are respectively disposed on the two mold bases 2. A fixing part 15 is provided on the mold unit 11, and a fastening block 3 is installed on the corresponding mold base 2. The fastening block 3 and the mold base 2 together clamp the fixing part 15 to fix the mold unit 11 on the corresponding mold base 2.

[0052] Specifically, such as Figure 1 , 6 As shown, one end of the fastening block 3 is connected to the mold base 2 by the first bolt 31, and the other end is clamped on the side of the fixing part 15 away from the corresponding mold base 2. A second bolt 32 is also installed between the two ends of the fastening block 3. The second bolt 32 is also connected to the mold base 2 to enhance the clamping ability of the other end of the fastening block 3 on the fixing part 15.

[0053] like Figure 7-11 As shown, Embodiment 2 of this utility model provides an injection mold 100, which includes two mold units 101 that are close to or far apart from each other in a predetermined direction. The predetermined direction is the conventional mold closing / opening direction of two mold units 101 in the injection molding field. The mold unit 101 includes a mold frame 103 and a mold core 102. The mold frame 103 of one mold unit 101 has a recessed mounting cavity 104 on the end face facing the other mold unit 101, and the corresponding mold core 102 is detachably assembled in the mounting cavity 104.

[0054] like Figure 8 As shown, in this embodiment, each mold unit 101 has a recessed mounting cavity 104 on the end face of the mold frame 103 facing another mold unit 101, and the corresponding mold core 102 is detachably assembled in the mounting cavity 104, so that each mold unit 101 is a detachable structure.

[0055] like Figure 8-10As shown, in this embodiment, the mold frame 103 has an assembly port 1041 on one side of the circumferential direction that communicates with the mounting cavity 104. The mold core 102 is assembled into the mounting cavity 104 from the assembly port 1041, and a locking mechanism for fixing the mold core 102 in the mounting cavity 104 is provided in the assembly port 1041.

[0056] like Figure 9-11 As shown, in this embodiment, the locking mechanism includes a positioning block 106 installed in the assembly port 1041. One end of the positioning block 106 facing the mounting cavity 104 is pressed and engaged with the mold core 102 to fix the mold core 102 in the mounting cavity 104.

[0057] Furthermore, to facilitate fixing the positioning block 106 to the mold frame 103, and to provide support for the extrusion fit between the positioning block 106 and the mold core 102, such as Figure 9-11 As shown, the positioning block 106 has a mounting part 1061 located outside the assembly port 1041. The mounting part 1061 is connected to the mold frame 103 by a bolt structure, that is, a fixing bolt 107 is installed on the mounting part 1061 and the fixing bolt 107 is connected to the mold frame 103.

[0058] Furthermore, such as Figure 8 As shown, in this embodiment, in order to prevent the mold core 102 from coming out of the mounting cavity 104 along the predetermined direction, the assembly port 1041 is provided with a sliding groove 1042 extending into the mounting cavity 104 on the inner wall on both sides of the assembly direction of the mold core 102. The mold core 102 is provided with a slide rail 1021 corresponding to the sliding groove 1042. The slide rail 1021 and the corresponding sliding groove 1042 are slidably engaged so that the mold core 102 is slidably assembled from the assembly port 1041 into the mounting cavity 104, and the mold core 102 is prevented from coming out of the mounting cavity 104 along the predetermined direction.

[0059] Assembly process reference for mold unit 101 Figure 8-10 Based on the above structural description, the assembly process is already clear, so it will not be described in words here.

[0060] When replacing the injection mold 100, only the mold core 102 needs to be replaced, without the need to disassemble and replace the entire injection mold 100. This makes disassembly and assembly more convenient, more efficient, and safer. Compared with the aforementioned embodiment 1, this embodiment adopts the slide rail 1021 and slide groove 1042 structure, which makes it easier for operators to disassemble and assemble the mold core 102. This embodiment also adds an operating handle 108 to the mold core 102, which further facilitates the disassembly and assembly of the mold core 102 by operators.

[0061] like Figure 7As shown, this utility model also relates to an injection molding assembly, including two mold bases 200 and an injection mold 100 as described above. Two mold units 101 of the injection mold 100 are respectively disposed on the two mold bases 200. Each mold unit 101 has a fixing part 105, and a fastening block 300 is installed on the corresponding mold base 200. The fastening block 300 and the mold base 200 together clamp the fixing part 105 to fix the mold unit 101 on the corresponding mold base 200. The structure of the fastening block 300 is the same as that of the fastening block 3 in the aforementioned embodiment, and therefore will not be described again.

[0062] In other embodiments besides the above embodiments, the locking mechanism can also adopt other forms of conventional fixing technology, such as set screws that are installed on the side wall of the mold frame. After the mold core is installed into the mounting cavity, the corresponding set screw is tightened so that one end enters the mounting cavity and presses against the corresponding outer side wall of the mold core, thereby locking the mold core. This type of locking mechanism is a conventional technology, and those skilled in the art can understand and easily obtain the specific structure and operation method, so it will not be shown or further described here.

[0063] Although specific embodiments of the present invention have been described in detail by way of examples, those skilled in the art should understand that the above examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Those skilled in the art should understand that modifications can be made to the above embodiments without departing from the scope and spirit of the present invention. The scope of the present invention is defined by the appended claims.
