Most traditional molds are designed so that the upper and lower molds of the mold are connected to the equipment through a template, and the upper and lower molds are fixed to the equipment by the upper template and the lower template respectively. However, since the upper template is large, the water block on the upper template cannot enter the equipment together with the upper template after being connected to the upper template. The water block can only be installed after the mold enters the equipment, which is complicated and inefficient; and each upper mold is equipped with an upper template, which is costly.

DETAILED DESCRIPTION

[0015] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments to help understand the content of the present invention. The methods used in the present invention are all conventional methods unless otherwise specified; the raw materials and devices used are all conventional commercial products unless otherwise specified.

[0016] Depend on Figure 1-Figure 2 As shown, the utility model provides a low-pressure differential casting mold without an upper mold connecting plate, including an upper mold 1 and a lower mold, and the upper mold 1 is connected to the equipment through a connecting frame 2 to realize automated production. Specifically, the connecting frame 2 is an inverted trapezoidal frame structure, which includes an upper connecting plate 21 and a lower connecting plate 22, and the upper connecting plate 21 and the lower connecting plate 22 are connected together by a plurality of connecting columns 23. The upper connecting plate 21, the lower connecting plate 22 and the connecting columns 23 are integrally formed to make the connecting frame 2 stronger and convenient for connection with the equipment.

[0017] In order to facilitate cooling of the mold, a cooling module 24 is provided on the side of the connection frame 2. The cooling module 24 includes an upper water block 241 and a lower water block 242. The upper water block 241 and the lower water block 242 are respectively fixed to the sides of the upper connection plate 21 and the lower connection plate 22 by bolts, and the upper water block 241 and the lower water block 242 are connected by a connecting pipe 243. In order to facilitate positioning and installing the water blocks, the upper connection plate 21 and the lower connection plate 22 are both provided with an L-shaped folding edge 211, and the upper water block 241 and the lower water block 242 are engaged on the L-shaped folding edge 211 and fixedly connected to the connection frame 2. Since the connecting frame 2 is designed as an inverted trapezoidal frame, the lower connecting plate 22 is smaller than the upper connecting plate 21, so that the connecting frame 2 can be adapted to the upper mold 1 in the smallest shape and is easy to assemble as a whole. The split design of the cooling module 24 can achieve the cooling effect while minimizing the area occupied by the upper water block 241 and the lower water block 242 after being fixed to the connecting frame 2 in the horizontal plane. Therefore, after the cooling module 24 is connected to the connecting frame 2, it can enter the equipment together with the connecting frame 2, and there is no need to install water blocks in the equipment, thereby improving production efficiency. The connecting frame 2 with an upper and lower two-layer frame structure can adapt to more upper molds 1, so that multiple sets of molds can share one connecting frame 2, which improves production efficiency while reducing production costs.

[0018] Furthermore, the upper connecting plate 21 and the lower connecting plate 22 are hollow inside, and the upper connecting plate 21 is cross-shaped inside to enhance the structural strength, while the lower connecting plate 22 is adapted to the size of the upper mold 1 and is fixedly connected to the upper mold 1 by bolts. The upper connecting plate 21 and the lower connecting plate 22 are hollow inside to reduce weight and facilitate the overall assembly of the equipment.

[0019] Furthermore, the lower water block 242 is connected to the water block on the side of the upper mold 1 through bolts; the upper water block 241 is connected to the water block on the equipment through bolts to achieve mold cooling.

[0020] A support plate 231 is further provided on the side of the connection column 23 to further enhance the strength of the connection frame 2 .

[0021] The utility model adopts a double-layer, smaller inverted trapezoidal frame structure connecting frame 2 to connect the device and the upper mold 1, and can fix the cooling module 24 together with the connecting frame 2 on the device, avoiding frequent disassembly and assembly. When in use, it is only necessary to fix the upper mold 1 and the connecting frame 2 together, thereby improving production efficiency. At the same time, the connecting frame 2 of the frame structure can be adapted to more upper molds 1, reducing production costs, improving the competitiveness of enterprises, and can be widely applied to the technical field of aluminum alloy casting molds.
