[0026] like Figure 1-4 As shown, this utility model provides a technical solution: a casting mold that facilitates demolding, including an upper mold 2 and a lower mold 3. An mounting plate 1 is fixedly connected to the top of the outer surface of the upper mold 2, and four supporting rods 4 are fixedly connected to the bottom of the outer surface of the lower mold 3. By setting the upper mold 2 and the lower mold 3, auxiliary shaping can be performed. An auxiliary demolding structure 5 is provided at the bottom and one side of the lower mold 3. A guide buffer structure 6 is provided between the upper mold 2 and the lower mold 3. The auxiliary demolding structure 5 includes a rectangular frame 51. One side of the outer surface of the rectangular frame 51 is fixedly connected to one side of the outer surface of the lower mold 3. A threaded rod 52 is rotatably connected to the top and bottom of the inner wall of the rectangular frame 51. The top of the outer surface of the threaded rod 52 passes through the top of the rectangular frame 51 and is fixedly connected to an operating block 53. By setting the threaded rod 52, it can work in conjunction with other components.
[0027] Specifically, such as Figures 2-3As shown, a threaded hole block 54 is threadedly connected to the outer surface of the threaded rod 52. The outer surface of the threaded hole block 54 is slidably connected to the inner wall of the rectangular frame 51. An auxiliary connecting rod 55 is fixedly connected to one side of the outer surface of the threaded hole block 54. A connecting plate 56 is fixedly connected to one end of the outer surface of the auxiliary connecting rod 55. By setting the auxiliary connecting rod 55 and the connecting plate 56, they can work together with other components. Several fixed round rods 57 are fixedly connected to the top of the outer surface of the connecting plate 56. A sliding cylinder 58 is slidably connected to the top of the outer surface of the fixed round rods 57. By setting the fixed round rods 57 and the sliding cylinder 58, they can work together with other components. A sliding cylinder 58 is fixedly connected to the top of the outer surface of the sliding cylinder 58. Ejector plate 510, by setting ejector plate 510, can cooperate with sliding cylinder 58 to eject products. The outer surface of fixed round rod 57 is fitted with return spring 59. The two ends of return spring 59 are fixedly connected to the outer surface of sliding cylinder 58 and connecting plate 56 respectively. The bottom of inner wall of lower mold 3 is provided with rectangular auxiliary groove 511. By setting rectangular auxiliary groove 511 and auxiliary round groove 512, it can cooperate with ejector plate 510 and other components to play a role. The inner wall of lower mold 3 is located on the inner wall of rectangular auxiliary groove 511 and auxiliary round groove 512 is provided. Sliding cylinder 58 is inserted into the inner wall of auxiliary round groove 512. Ejector plate 510 is engaged when it is separated from inner wall of rectangular auxiliary groove 511.
[0028] Specifically, such as Figure 3 and Figure 4 As shown, the guide buffer structure 6 includes a fixed rod 61. The bottom end of the outer surface of the fixed rod 61 is fixedly connected to the top end of the outer surface of the lower mold 3. A sliding cylinder 62 is slidably connected to the top end of the outer surface of the fixed rod 61. By setting the fixed rod 61 and the sliding cylinder 62, they can work with the buffer spring 63 to buffer and guide. The outer surface of the fixed rod 61 is fitted with the buffer spring 63. The two ends of the buffer spring 63 are fixedly connected to the sliding cylinder 62 and the lower mold 3, respectively. An auxiliary insertion hole 64 is opened at the bottom of the outer surface of the upper mold 2. The sliding cylinder 62 is inserted into the inner wall of the auxiliary insertion hole 64. By setting the auxiliary insertion hole 64, it can work with the sliding cylinder 62 to guide.
[0029] The working principle of this utility model is as follows:
[0030] S1. In use, the upper mold 2 and the lower mold 3 allow the sliding cylinder 62 to slide on the inner wall of the auxiliary insertion hole 64, thereby abutting the sliding cylinder 62 against the outer surface of the fixed rod 61, which in turn causes the buffer spring 63 to deform, thus providing buffering.
[0031] S2. After the product is shaped, rotate the threaded rod 52 so that the threaded rod 52 can drive the threaded hole block 54 to move, which in turn can drive the auxiliary connecting rod 55 and the connecting plate 56 to move, which in turn can drive the ejector plate 510 to move, so that the product is ejected from the interior of the lower mold 3.
[0032] S3. During the ejection process, the sliding cylinder 62 can slide on the outer surface of the fixed rod 61, which in turn can cause the buffer spring 63 to deform, thus cooperating with the ejection plate 510 to provide auxiliary buffering.
[0033] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0034] The preferred embodiments of this patent have been described in detail above. However, this patent is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this patent.
