The contact area between the magnesium alloy sheet and the lower mold body is smaller, which is convenient for separation and demoulding. The upper die head and the lower mold body are provided with multiple groups that can be adjusted and paired by a motor, and can be quickly replaced according to the production needs of the magnesium alloy sheet, and the magnesium alloy sheet is easier to separate from the mold after pressing and forming, avoiding the phenomenon that the bottom is unable to be separated due to adhesion due to factors such as air pressure, thereby improving the production efficiency of the magnesium alloy sheet.

[0004] However, the device is not designed with a transmission device, and the mold needs to be moved manually, and the degree of automation needs to be improved. Utility Model Content

[0005] In view of the deficiencies of the prior art, the purpose of the present utility model is to provide a magnesium alloy extrusion device with a transmission mechanism to solve the problem that the magnesium alloy sheet extrusion forming device in the above-mentioned background technology has no transmission device and the degree of automation needs to be improved.

[0006] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0007] A magnesium alloy extrusion device with a transmission mechanism comprises a workbench, a transmission mechanism is arranged on the top of the workbench, and an extrusion mechanism is installed on the top of the workbench;

[0008] The transmission mechanism includes a conveyor belt, a fixed frame is fixedly connected to the outside of the conveyor belt, one end of the fixed frame is fixedly connected to a first cylinder, one end of the first cylinder is fixedly connected to a clamping frame, an electric heating tube is installed on the inner side of the clamping frame, a sealing shell is fixedly connected to the top of the clamping frame, an infrared thermometer is installed on the inner side of the sealing shell, and a limiting component is arranged on the inner side of the conveyor belt.

[0009] Preferably, the limiting assembly comprises an electric telescopic rod, one end of which is fixedly connected to a limiting frame, a rotating shaft is installed inside the limiting frame, and a limiting roller is installed outside the rotating shaft.

[0010] Preferably, two electric telescopic rods are provided, and both of the two electric telescopic rods are fixedly connected to the inner side of the conveyor belt.

[0011] Preferably, through holes are provided on the left and right sides of the conveyor belt, and the clamping frame is configured to be concave.

[0012] Preferably, the extrusion mechanism includes an extrusion frame, a second cylinder is fixedly connected to the inner side of the extrusion frame, a connecting frame is installed at the bottom of the second cylinder, a fixed block is clamped at the bottom of the connecting frame, a fixed column is clamped on the outside of the fixed block, and an upper die head is installed at the bottom of the fixed block.

[0013] Preferably, the extrusion frame is configured to be concave, and the extrusion frame is fixedly connected to the top of the conveyor belt.

[0014] Preferably, the fixing block is configured to be convex, and the fixing column passes through the fixing block and extends to the outside of the connecting frame.

[0015] Compared with the prior art, the beneficial effects achieved by the utility model are:

[0016] First, by placing the lower die on the conveyor belt, the lower die is driven by the conveyor belt to the raw material unloading position, so that the magnesium alloy raw material enters the lower die, and then the conveyor belt continues to drive the lower die to the extrusion frame, and then the photoelectric sensor is installed through the conveyor belt, so that when the lower die arrives, the electric telescopic rod is started to drive the limit frame to be pushed out, so that the limit roller contacts the outer wall of the lower die, and the lower die is straightened to avoid tilting during transmission. The limit roller can be rotated by the set rotating shaft to avoid affecting the transportation of the lower die, and then the lower die arrives under the extrusion frame, and the first cylinder is started to push the clamping frame so that the clamping frame clamps the lower die, fixes the lower die, and merges the sealing shell to seal the lower die. The magnesium alloy raw material in the lower die is heated by starting the electric heating tube, and the temperature is detected by the infrared thermometer, so that the magnesium alloy raw material reaches a temperature suitable for extrusion, and then the clamping frame is retracted, and the upper die head is lowered for extrusion. After the extrusion is completed, the conveyor belt transmits the lower die, and the next lower die is then transmitted to the extrusion frame, so that continuous extrusion can be performed. The set conveyor belt reduces the handling of personnel and improves the automation of the device.

[0017] Second, by starting the second cylinder to drive the connecting frame to descend, and then drive the upper die head at the bottom to descend, the magnesium alloy raw material in the lower die is extruded and formed, and the extrusion operation is completed. When the upper die head needs to be replaced, just pull out the fixing column to release the connection between the fixing block and the connecting frame, and then the upper die head can be removed for replacement, so as to facilitate the operation of replacing the upper die head.
