AI Technical Summary
Existing molds for processing bulletproof shields require waiting for the raw material to cool and solidify naturally in the lower mold before it can be removed, resulting in low processing efficiency.
The system employs a cooling component and a demolding component. The cooling component accelerates the cooling of the raw material inside the lower mold through a water pump and cooling pipes, while the demolding component pushes the demolding rod through a hydraulic rod to eject the cooled and formed shield.
This technology enables rapid cooling and molding of the shields, as well as convenient demolding, thereby improving the production efficiency of shield injection molding.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] Example 1:
[0026] like Figures 1-5 As shown: The system includes a base plate 1, with support columns 2 fixedly installed at the four corners of the top surface of the base plate 1. A lower mold 3 is fixedly installed on the top surface of the support columns 2. An upper mold 4 is located above the lower mold 3. An injection molding pipe 41 is fixedly connected to one side of the top surface of the upper mold 4. A lifting assembly 5 is located on the rear side of the base plate 1. A demolding assembly 6 and a cooling assembly 7 are located at the bottom of the lower mold 3. The cooling assembly 7 includes a water pump 71 fixedly installed on one side of the top surface of the base plate 1. A water inlet pipe 72 is fixedly connected to the water inlet end of the water pump 71, and the water inlet pipe 72 is connected to an external water source. A connecting pipe 73 is fixedly connected to the output end of the water pump 71. The end of the connecting pipe 73 away from the water pump 71 is fixedly connected to the bottom surface of a distribution pipe 74. Cooling pipes 75 arranged in a linear array are fixedly installed on the side wall of the distribution pipe 74. The end of the cooling pipes 75 away from the distribution pipe 74 is fixedly connected to a collecting pipe 76. On the side wall, the bottom surface of the collecting pipe 76 is fixedly connected to the drain pipe 77. The branch pipe 74 and the cooling pipe 75 are respectively fixedly installed on the left and right sides of the bottom surface of the lower mold 3. The outline of the cooling pipe 75 matches the outline of the bottom surface of the lower mold 3. The top surface of the cooling pipe 75 contacts the bottom surface of the lower mold 3. The cooling pipe 75 is made of pure copper and has a rectangular cross-section. The water pump 71 delivers external water to the inside of the branch pipe 74. Then the water enters the inside of the collecting pipe 76 through the cooling pipe 75 and is finally discharged through the drain pipe 77. During this process, the heat of the raw material inside the lower mold 3 is conducted into the lower mold 3. The cooling pipe 75 absorbs the heat inside the lower mold 3 and dissipates it to the outside. The water inside the cooling pipe 75 cools the cooling pipe 75 quickly, achieving the purpose of quickly cooling and molding the raw material inside the lower mold 3, which is beneficial to improving the efficiency of shield injection molding.
[0027] Example 2:
[0028] like Figures 1-4As shown: The lower mold 3 has a cavity in the middle, and the bottom surface of the upper mold 4 has a mold core that matches the cavity. A linear array of demolding holes 31 are formed through the center of the bottom surface of the cavity. The demolding assembly 6 includes a second hydraulic rod 61, a mounting plate 62, and a demolding rod 63. The second hydraulic rod 61 is fixedly installed in the middle of the top surface of the base plate 1. The output end of the second hydraulic rod 61 is fixedly installed with the mounting plate 62. The top surface of the mounting plate 62 is fixedly installed with the demolding rod 63, which corresponds to the demolding holes 31. The corresponding setting and the diameter is the same as the diameter of the demolding hole 31. The demolding rod 63 is movably fitted inside the demolding hole 31. The demolding rod 63 and the cooling pipe 75 are staggered. The second hydraulic rod 61 pushes the mounting plate 62 and the demolding rod 63 upward, so that the demolding rod 63 passes through the demolding hole 31 and enters the interior of the lower mold 3. Then, the demolding rod 63 pushes the shield that has cooled and formed inside the lower mold 3 upward, so as to facilitate the demolding of the cooled and formed shield, thereby further improving the efficiency of shield injection molding production.
[0029] Example 3:

The output end of the first hydraulic rod 52 passes through the top surface of the L-shaped plate 51 and is fixedly installed on the top surface of the upper mold 4. The upper mold 4 is moved up and down by the L-shaped plate 51, thereby completing the mold closing and mold opening work of the lower mold 3 and the upper mold 4.
[0031] The working principle and usage process of this utility model: When using this easily demolded PC shield injection mold, the L-shaped plate 51 is activated to push the upper mold 4 downwards, closing the upper mold 4 with the lower mold 3. Then, molten PC material is transported through the injection pipe 41 into the cavity between the lower mold 3 and the upper mold 4. Next, the water pump 71 is activated to transport external water into the connecting pipe 73. The water then enters the interior of the diversion pipe 74 through the connecting pipe 73, and then enters the interior of the collection pipe 76 through the cooling pipe 75, finally being discharged through the drain pipe 77. During this process, the heat of the material inside the lower mold 3 is released. The heat is conducted into the lower mold 3, and the cooling pipe 75 absorbs the heat inside the lower mold 3 and dissipates it to the outside. The water inside the cooling pipe 75 cools the cooling pipe 75 quickly, thereby accelerating the cooling rate of the raw material inside the lower mold 3. After the raw material inside the lower mold 3 has cooled and solidified, the L-shaped plate 51 is activated to move the upper mold 4 upward. Then, the second hydraulic rod 61 is activated to push the mounting plate 62 and the demolding rod 63 upward, so that the demolding rod 63 passes through the demolding hole 31 and enters the interior of the lower mold 3. Then, the demolding rod 63 pushes the shield that has cooled and solidified inside the lower mold 3 upward, thus completing the demolding of the shield.
