[0014] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0015] 1. The utility model discloses an automobile gear stamping die with an ejection mechanism. When the die needs to be used, an operator stands at the through-cavity opening side, the user turns on the first motor, the first motor drives the first screw rod to rotate in the positive direction, the first screw rod drives the movable plate to move along the limit rod in the direction away from the first motor, the movable plate drives the lower mounting cavity seat and the lower mold component to move out from one side of the through-cavity, until the lower mold component drives multiple groups of unit mold components to move out of the through-cavity, after the unit mold component moves in front of the operator, the first motor is turned off, the operator can respectively and quantitatively inject the mold stock liquid for manufacturing the gear into each group of gear forming grooves, when the injection is completed, the user turns on the first motor, so that the first motor drives the first screw rod to rotate in the opposite direction, the first screw rod drives the movable plate to move along the limit rod in the direction close to the first motor, the movable plate drives the lower mounting cavity seat and the lower mold component to shrink into the through-cavity, until the lower mold component moves to the position directly below the upper mold component The upper mold component and the multiple unit mold components complete the mold closing work. After the workpiece is pressed, wait for the multiple gears to cool and form. After the workpiece is formed, start the multiple hydraulic cylinders at the same time. The multiple hydraulic cylinders extend to drive the upper mold component to move upward, so that the upper mold component completely leaves the multiple unit mold components, and the top plate returns to its original position. Subsequently, wait for the operator to take the formed gear. This setting enables the upper and lower molds to be separated and closed quickly during the manufacturing process of the gear mold, thereby improving the convenience of operation.

The multiple groups of unit die components move out of the support seat assembly. At this time, the user can turn on the second motor. The rotation of the second motor drives the roller on one side to rotate. Due to the transmission of the belt, the two groups of rollers rotate in the same direction, and the rollers drive the long rod and the positive and negative screws to rotate. The positive rotation of the positive and negative screws drives the two groups of moving blocks to move closer to each other, so that the top ends of the two adjacent connecting rod components are lifted, the angle between the two adjacent connecting rod components becomes smaller, and the connecting column performs an ascending movement, so that the two groups of connecting columns simultaneously pass through the long slot to the bottom of the lower die component.

After the lower mold component is disengaged from the lower mounting cavity seat, it is convenient for the user to directly remove the lower mold component and multiple sets of gear workpieces. This operation assists the staff in taking out the formed workpieces; subsequently, the second motor drives the two sets of rollers to rotate in the opposite direction, and then the two sets of positive and negative screw rods rotate in the opposite direction, and then the two adjacent sets of moving blocks move away from each other, and the two sets of connecting rotating columns will move downward until the two sets of connecting rotating columns are retracted into the lower mounting cavity seat again. The user re-inserts and installs the lower mold component on one side of the lower mounting cavity seat, and then uses the driving assembly to transfer the ejection assembly and the lower mold component to the inside of the through cavity to restore the initial in-situ state.

The moving plate 32 drives the lower mounting cavity seat 21 and the lower die component 4 to move out from one side of the through cavity 11 until the lower die component 4 drives the multiple sets of unit die components 41 to move out. After the unit mold component 41 moves to the front of the operator, the first motor 31 is turned off. The operator can quantitatively inject the mold stock liquid for manufacturing the gear into each group of gear forming grooves 42. When the injection is completed, the user turns on the first motor 31, so that the first motor 31 drives the first screw rod 34 to rotate in the opposite direction.

The upper mold part 15 and the multiple unit mold parts 41 complete the mold closing work. After the workpiece is pressed, wait for the multiple gears to cool and form. After the workpiece is formed, start the multiple hydraulic cylinders 13 at the same time. The multiple hydraulic cylinders 13 extend and drive the upper mold part 15 to move upward, so that the upper mold part 15 completely leaves the multiple unit mold parts 41. The top plate 14 returns to its original position, and then waits for the operator to take the formed gear. This setting enables the upper and lower molds to be quickly separated and molded in the gear mold manufacturing process, thereby improving the convenience of operation. At the same time, the gear mold can be automatically moved out and in from the support seat assembly 1, thereby assisting the operator in loading and unloading. The operation is simple and the working efficiency of the device is improved.

[0033] When the upper mold component 15 completely leaves the multiple sets of unit mold components 41, the operator needs to take the material of the formed gear later, and the user can drive the first motor 31 again, and the first motor 31 drives the first screw 34 to rotate, and the first screw 34 drives the moving plate 32 to move, and the moving plate 32 drives the lower mounting cavity seat 21 and the lower mold component 4 to move out of the through cavity 11, and the multiple sets of unit mold components 41 move out of the support seat assembly 1. At this time, the user can turn on the second motor 22, and the second motor 22 rotates to drive the roller 2 on one side thereof. 51 rotates, due to the transmission of the belt 26, the two groups of rollers 251 rotate in the same direction, the rollers 251 drive the long rod 252 and the positive and negative threaded rods 253 to rotate, the positive and negative threaded rods 253 rotate forward and drive the two groups of moving blocks 254 to move closer to each other, so that the top ends of the two groups of adjacent connecting rod parts 255 are lifted, the angle between the two groups of adjacent connecting rod parts 255 becomes smaller, the connecting rod 256 is raised, and the two groups of connecting rods 256 simultaneously pass through the long slot 24 to push the bottom of the lower mold part 4. After the lower mold part 4 is disengaged from the lower mounting cavity seat 21, the user can directly remove the lower mold part 4 and multiple groups of gear workpieces. This operation assists the staff in taking out the formed workpieces; subsequently, the second motor 22 drives the two groups of rollers 251 to rotate in the opposite direction, and then the two groups of positive and negative screw rods 253 rotate in the opposite direction, and then the two adjacent groups of moving blocks 254 move away from each other, and the two groups of connecting rotating columns 256 will move downward until the two groups of connecting rotating columns 256 retract into the lower mounting cavity seat 21 again. The user re-inserts and installs the lower mold part 4 on one side of the lower mounting cavity seat 21, and then uses the driving component 3 to transfer the ejection component 2 and the lower mold part 4 to the inside of the through cavity 11 to restore the initial original position.
