DETAILED DESCRIPTION

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments. The present invention includes but is not limited to the following embodiments.

[0022] like Figure 1-Figure 2 As shown, the utility model provides a pneumatic demoulding aluminum alloy mold, comprising: a base 1, a support plate 2, and a support rod 3;

The rear end face of the protective net 4 is open, and the rear end face of the protective net 4 is matched with the shape of the support plate 2. The two are in a bolted connection. The rear end face of the support plate 2 is installed with a pickup port 21, and the pickup port 21 has a door body hinged thereto. During operation, after the workpiece is cast and ejected by the pneumatic component, since the size of the top surface of the base 1 is smaller than the bottom surface size of the lower mold 32, a protective channel is formed between the outer side of the lower mold 32 and the protective net 4 to collect and process the workpiece.

[0024] Preferably, in one embodiment, Figure 2-Figure 3As shown, the protective net 4 as a whole is composed of a vertical network segment 42 and an extended network segment 43. The extended network segment 43 is in the upper part as a whole, and the highest point of the extended network segment 43 is higher than the top surface of the lower mold 32. The extended network segment 43 is gradually expanded from bottom to top. The bottom plate 41 of the protective net 4 is provided with an installation port, and a heat dissipation component 5 is installed in the installation port. The inner side surfaces of the bottom plate 41, the vertical network segment 42 and the extended network segment 43 are all covered with a porous soft thermal insulation pad. When working, the workpiece is lifted up and enters the interior of the protective net 4. With the structural setting of the extended network segment 43, it gradually falls into the top surface of the bottom plate 41, which is convenient for protecting the workpiece and helps to better collect and process the workpiece. When the workpiece is placed, it can also exchange heat with the external air for cooling, thereby improving the practicality of the overall device.

[0025] Preferably, in one embodiment, Figure 2 、 Figure 4 As shown, the heat dissipation component 5 is composed of a bellows 51, a connecting pipe 52, an exhaust plate 53, and an exhaust port 54.

[0028] Working principle of this utility model:

[0029] During operation, after the workpiece is cast and pushed out by the pneumatic component, since the size of the top surface of the base 1 is smaller than the bottom surface size of the lower mold 32, a protective channel is formed between the outer side of the lower mold 32 and the protective net 4 to collect and process the workpiece. After the workpiece is lifted, it enters the interior of the protective net 4. With the structural setting of the expanded network segment 43, it gradually falls to the top surface of the bottom plate 41, which is convenient for protecting the workpiece and helps to better collect and process the workpiece. When the workpiece is placed, it can also be cooled by heat exchange with the external air, thereby improving the practicality of the overall device. The air is supplied to the interior of the exhaust plate 53 through the external fan, and cooling air is supplied to the interior of the protective net through the exhaust port 54, so that the workpiece is cooled more quickly. The air guide plate 55 is arranged at multiple angles, which helps to improve the air outlet angle and the air outlet coverage.
