[0027] refer to Figures 1 to 8 According to a preferred embodiment of the present invention, a rotatable upper mold structure is provided, wherein the structure of the rotatable upper mold structure is as follows: Figure 1 As shown, the rotatable upper mold structure includes an upper mold assembly 10, wherein, as... Figure 1 The mold structure shown is described below. It should be noted that the mold closing and opening are conventional existing technologies, and the operating principle should be known to those skilled in the art. That is, the mold structure includes an upper mold assembly 10 and a lower mold assembly. The upper mold assembly 10 is fixed, and the lower mold assembly is driven by the force of an external driving component to move the lower mold assembly a predetermined distance toward or away from the upper mold assembly 10.

[0028] It is worth mentioning that this application differs from existing molds in that the upper mold component 10, as shown in the example... Figure 1 The structure shown can rotate during mold opening and closing. The rotation method is described in detail below to facilitate understanding of the operating principle of this application. Specifically, the upper mold assembly 10 includes a base plate 11, a first connecting plate 12, and a second connecting plate 13. The base plate 11 cooperates with the first connecting plate 12, and the connection method can be implemented as a bolt connection. The base plate 11 can be fixed to an external injection molding machine, and the first connecting plate 12 cooperates with the second connecting plate 13.

[0029] Specifically, the second connecting plate 13 has a central assembly cavity 1301, and the sidewall forming the assembly cavity 1301 also has a plurality of mounting slots 1302. The plurality of mounting slots 1302 and the assembly cavity 1301 both penetrate the second connecting plate 13, and the plurality of mounting slots 1302 are arranged in a ring array. In addition, the number of the plurality of mounting slots 1302 can be four.

[0030] Furthermore, the mounting groove 1302 is a T-shaped insertion groove, and the bottom wall forming the mounting groove 1302 also has a rectangular block 13021, the structure of which is as follows: Figure 2 As shown.

[0031] In addition, the rotatable upper mold structure also includes a plurality of guide blocks 20, which are evenly distributed on the second connecting plate 13. Specifically, the plurality of guide blocks 20 respectively cooperate with the plurality of mounting grooves 1302.

[0032] Furthermore, each guide block 20 has an insertion portion 21, a first abutment portion 22, and a guide portion 23. The insertion portion 21, the first abutment portion 22, and the guide portion 23 are integrally formed, specifically by machining. The insertion portion 21 is inserted into the corresponding mounting groove 1302, while the first abutment portion 22 abuts against the top of the rectangular stop block 13021 to define the position of the guide block 20. It should also be noted that multiple guide portions 23 are placed within the assembly cavity 1301.

[0033] It is worth mentioning that the rotatable upper mold structure also includes an upper mold head 30, which has a second abutting portion 31 and a mating portion 32. The second abutting portion 31 and the mating portion 32 are integrally formed. Those skilled in the art should understand that the mating portion 32 of the upper mold head 30 can mate with the lower mold head of the lower mold assembly to form a mold cavity, and the structure of the mold cavity is as follows... Figure 8 As shown.

[0034] Specifically, the structure of the first connecting plate 12 is as follows: Figure 6 As shown, the center of the side facing the second connecting plate 13 has a first mounting hole 1201 and a second mounting hole 1202. The size of the second mounting hole 1202 is larger than the size of the first mounting hole 1201. The second abutting part 31 of the upper mold head 30 is disposed in the first mounting hole 1201. At the same time, a limiting ring 40 is fixed at the second mounting hole 1202 to limit the position of the second abutting part 31. It is worth mentioning that the depth of the first mounting hole 1201 is greater than the thickness of the second abutting part 31, so that the limiting ring 40 is spaced apart from the second abutting part 31 by a predetermined distance, thereby allowing the guide block 20 to shift back and forth by a predetermined distance. It should be noted that the guide portion 23 is inclined, and the outer wall of the mating portion 32 also has multiple guide grooves 301. These guide grooves 301 respectively engage with multiple guide portions 23 to limit the movement direction of the upper mold head 30. That is, during the demolding process, the lower mold head 100 of the lower mold assembly applies a force to the mating portion 32 of the upper mold head 30, causing the second abutment portion 31 of the upper mold head 30 to move a predetermined distance and abut against the limiting ring 40. Simultaneously, guided by the guide portion 23, the upper mold head 30 deflects at a predetermined angle along the inclined direction of the guide portion 23, so that the upper mold head 30 and the lower mold head 100 can be smoothly separated. Figure 6The mating part 32 shown at point A is offset in the direction of the arrow.

[0035] In summary, the rotatable upper mold structure described in the embodiments of this application has been clarified, which provides advantages such as ease of use, simple structure, and rotatability.
