Description

Technical Field

[0001] The utility model relates to the technical field of die-casting molds for circuit baking trays, and more specifically, the utility model relates to a die-casting mold for a circuit baking tray. Background Art

[0002] Die casting is a metal casting process, which is characterized by applying high pressure to the melted metal using the inner cavity of the mold. The mold is usually processed from an alloy with higher strength. This process is somewhat similar to injection molding. Most die-cast castings are non-ferrous, such as zinc, copper, aluminum, magnesium, lead, tin, and lead-tin alloys and their alloys. Depending on the type of die casting, a cold chamber die-casting machine or a hot chamber die-casting machine needs to be used. The cost of casting equipment and molds is high. Therefore, the die-casting process is generally only used for mass production of a large number of products. Based on the traditional die-casting process, several improved processes have emerged, including the no-porosity die-casting process that reduces casting defects and eliminates air holes, which is mainly used for processing zinc, the direct injection process that can reduce waste and increase the yield rate, and new die-casting processes such as the precision speed and density die-casting technology invented by General Dynamics and semi-solid die casting. When the existing die-casting mold for a circuit baking tray is in use, the formed circuit baking tray is often at a high temperature. When the staff uses tools to clamp and remove the circuit baking tray, there are great safety hazards. If the clamping is not firm and the circuit baking tray falls, it will cause damage to the machine and even scald the staff. Therefore, it needs to be improved and optimized.

[0010] As a preferred technical solution of the utility model, a fixing rod is fixedly installed in the middle of the gear, the fixing rod is fixedly connected to the output shaft of the second motor, and limit blocks are fixedly installed at both ends of the rack.

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0012] 1.

At the same time, the precise positioning also reduces the risk of accidents when the staff retrieves the baking tray, simplifies the operation process, and reduces the labor intensity.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] As Figures 1 to 5As shown, the utility model provides a die-casting mold for a circuit baking tray, including a clamping block 9, a vortex rod 10 and two turbines 11 are rotatably installed inside the clamping block 9, the two turbines 11 are meshed with the vortex rod 10, a transmission rod 12 is fixedly installed in the middle of the two turbines 11, the two transmission rods 12 extend to the outside of the clamping block 9, connecting strips 14 are fixedly installed on the outer surfaces of both ends of the two transmission rods 12, and two clamping arms 15 are hingedly installed at the other ends of the four connecting strips 14.

[0022] The staff starts the device, and the pressure table 2 moves to the left, driving the die-casting table 4 and the mold 5 to be relatively die-casted, so that the formed baking tray 6 is attached to the surface of the die-casting table 4, and the motor 16 is started. The output shaft of the motor 16 drives the worm 10 to rotate, and the worm 10 drives the two turbines 11 to rotate. The two turbines 11 drive the two transmission rods 12 to rotate, and the two transmission rods 12 drive the four connecting strips 14 located at both ends of the transmission rod 12 to rotate, and the four connecting strips 14 drive the two clamping arms 15 to clamp relative to each other, and the two clamping arms 15 move relative to each other to clamp the baking tray 6.

[0023] By starting the motor 16, the output shaft of the motor 16 drives the worm 10 to rotate, the worm 10 drives the two turbines 11 to rotate, and the two turbines 11 drive the transmission rod 12 to rotate so that the transmission rod 12 drives the connecting bar 14 to swing, so that the two clamping arms 15 move relative to each other to clamp the baking tray 6. The output shaft of the motor 16 directly drives the worm 10 to rotate, and the worm 10 drives the two turbines 11 to rotate. This design realizes efficient power transmission, reduces energy loss, and improves work efficiency. Compared with traditional devices, it avoids contact with staff. Due to the high efficiency of power transmission, the two clamping arms 15 can obtain greater clamping force when they move relative to each other. This design enables the clamping arms 15 to clamp the baking tray 6 more firmly, and maintain a stable clamping state even in a high temperature environment, effectively avoiding production accidents caused by accidental falling off of the baking tray, and providing a safer working environment for production personnel.

[0024] Among them, the front of the clamping block 9 is fixedly installed with a motor protection box 8, the front of the motor protection box 8 is fixedly installed with a hydraulic cylinder 7, the front of the hydraulic cylinder 7 is fixedly installed with a fixed block 17, the bottom of the fixed block 17 is fixedly installed with a transmission rod 18, the front of the transmission rod 18 is fixedly installed with a rack 19, the front of the rack 19 is fixedly installed with a gear 20 and the gear 20 is meshed with the rack 19.

[0025] The staff starts motor 16, and motor 16 drives the clamping arm 15 to firmly clamp the baking tray 6. Then, the hydraulic cylinder 7 is started. The output shaft of the hydraulic cylinder 7 drives the clamping arm 15 to move telescopically, and the clamping arm 15 drives the baking tray 6 to move telescopically, causing the baking tray 6 to move forward. Then, motor 22 is started. The output shaft of motor 22 drives the fixed rod 21 to rotate, and the fixed rod 21 drives the rack 19 to move left and right on the surface of the fixed table 23. The rack 19 drives the transmission rod 18 to move left and right, and the transmission rod 18 drives the fixed block 17 to move left and right. The fixed block 17 drives the hydraulic cylinder 7 to move left and right.

[0026] By starting the hydraulic cylinder 7, when the clamping arm 15 firmly clamps the baking tray 6, the telescopic movement of the output shaft of the hydraulic cylinder 7 drives the baking tray 6 to move forward. Then, motor 22 is started. Motor 22 drives the gear 20 to drive the rack 19 to move left and right. The rack 19 drives the transmission rod 18 to move left and right, causing the fixed block 17 to drive the hydraulic cylinder 7 to move left, center, and right. The hydraulic cylinder 7 drives the baking tray 6 to move, enabling the baking tray 6 to be moved to the optimal position for the staff to pick up. Compared with traditional devices, through the precise transmission of the gear 20 and the rack 19 driven by motor 22, as well as the stable support of the transmission rod 18 and the fixed block 17, the movement and positioning of the baking tray 6 reach extremely high precision, reducing potential safety hazards caused by sudden movement or inaccurate positioning.
