However, the above structure still has the following problems in actual use:

[0003] The above structure completes the injection molding of the mold through the cooperation between the upper mold and the lower mold. After injection molding, since there is no automatic demolding mechanism, manual demolding is required. However, the newly formed mold has a high temperature, and manual demolding is prone to the risk of scalding.

[0004] Therefore, we proposed that the integral injection mold for the production of phone casing can solve the above problems well. Utility Model Content

It is simple and convenient, and can also avoid the high temperature of the mold to scald the staff, thereby improving safety;

[0018] The gear rod rises, causing the gear to drive the shaft rod to rotate, causing the shaft rod to relax the pull rope, so that the pull rope no longer exerts pulling force on the lifting rod;

[0019] (2) Further, the gear rotates in the opposite direction, thereby driving the fixed shaft to rotate, so that the shaft reels the pull rope, and the pull rope pulls the lifting rod downward, so that the lifting rod drives the push plate to reset;

[0020] (3) When the upper mold and the lower mold fit together, the upper mold will also drive the positioning rod to fit together with the lower mold, thereby achieving the positioning effect between the upper mold and the lower mold, thereby avoiding the phenomenon of left and right displacement between the upper mold and the lower mold;

[0030] See also Figure 1-Figure 6 , the utility model provides the following technical solutions:

[0031] Embodiment 1: In order to solve the problem in the prior art that manual demoulding is required, but the newly formed mold has a high temperature and manual demoulding is prone to the risk of scalding, the following scheme is disclosed, including a base 1, a column 2 is fixed to the upper surface of the base 1, and the upper end of the column 2 is fixed to the top plate 3; it also includes: a lower mold 10 is fixed to the upper surface of the base 1, and a mold groove 15 is fixedly provided on the inner side of the lower mold 10, and a push plate 13 is embedded in the lower end of the mold groove 15, and a lifting rod 12 is fixed to the lower end of the push plate 13; the lower end of the lifting rod 12 passes through the base 1 and is fixed to the reset spring 14, and the lower end of the reset spring 14 is fixed to the base 1, and the lifting rod 12 is slidably connected to the base 1 and the mold groove 15; the lower end of the lifting rod 12 is fixed to the pull rope 11, and the other end of the pull rope 11 is wrapped around the outer side of the shaft 9;

[0032] When the upper mold 5 is separated from the lower mold 10, the gear rod 7 will be driven to rise together, and the gear rod 7 will rise, thereby driving the gear 8 to rotate. The gear 8 rotates, so that the gear 8 drives the shaft rod 9 to rotate, and then the shaft rod 9 relaxes the pull rope 11. At this time, the pull rope 11 no longer generates tension on the lifting rod 12. At this time, the elastic force of the reset spring 14 drives the lifting rod 12 to rise, so that the lifting rod 12 drives the push plate 13 to rise together, and then the push plate 13 pushes the housing in the mold groove 15 out, thereby achieving the effect of automatic demoulding, and no manual demoulding is required. It is simple and convenient, and it can also avoid the high temperature of the mold to scald the staff, thereby improving safety.

[0033] Embodiment 2: Different from Embodiment 1, this embodiment facilitates the reset of the push plate 13, thereby facilitating the next demoulding. For details, refer to Figure 1-Figure 2 and Figure 4-Figure 5 , a cylinder 4 is fixed to the upper surface of the top plate 3 by bolts, and the lower end of the cylinder 4 penetrates the top plate 3 and is fixed to the upper mold 5, and a gear rod 7 is fixed to the left side of the lower surface of the upper mold 5, and the right side of the gear rod 7 is meshed with a gear 8, and the gear 8 is fixed to the outer side of the shaft rod 9, and the front and rear ends of the shaft rod 9 are both connected to the lower mold 10 bearing, and a matching groove is provided on the lower surface of the upper mold 5, and the matching groove and the upper mold 5 are matched, and an injection port is provided on the upper surface of the upper mold 5, and the lower end of the injection port penetrates the upper mold 5;

[0034] The upper mold 5 is driven down by the cylinder 4, so that the upper mold 5 and the lower mold 10 fit together. When the upper mold 5 and the lower mold 10 fit together, the gear rod 7 is driven to mesh with the gear 8, so that the gear 8 rotates in the opposite direction. The gear 8 rotates, and then the fixed shaft rod 9 is driven to rotate, so that the shaft rod 9 reels the pull rope 11, and then the pull rope 11 pulls the lifting rod 12 downward, so that the lifting rod 12 drives the push plate 13 to reset, and then the injection molding of the raw material can be realized through the injection molding port opened on the upper surface of the lower mold 10, and then the mold groove 15 can be injected, and it is convenient for demolding next time;

[0035] Embodiment 3: Different from Embodiment 2, this embodiment can avoid air affecting the quality of mold injection molding. Figure 1-Figure 2 and Figure 6 A positioning rod 6 is fixed on the right side of the lower surface of the upper mold 5, and the positioning rod 6 is matched with the lower mold 10, and a sealing strip 17 is also bonded to the lower surface of the upper mold 5, and the sealing strip 17 is matched with the matching plate 16, and the lower end of the matching plate 16 is fixed to the lower mold 10, and the matching plate 16 is arranged in a square frame structure;

[0036] When the upper mold 5 and the lower mold 10 fit together, the upper mold 5 will also drive the positioning rod 6 to fit together with the lower mold 10. Through the setting of the positioning rod 6, the positioning effect between the upper mold 5 and the lower mold 10 is achieved, thereby avoiding the left and right displacement of the upper mold 5 and the lower mold 10. At the same time, when the upper mold 5 and the lower mold 10 fit together, the upper mold 5 will also drive the sealing strip 17 and the fitting plate 16 to fit together. Through the fit between the fitting plate 16 and the sealing strip 17, a sealing effect is achieved, thereby preventing the entry of air during injection molding, and preventing air from affecting the quality of mold injection molding.
