9. An injection molding apparatus for full mold release of aluminum material as claimed in claim 1, wherein: the injection molding method of the injection molding equipment comprises the following specific steps:
s1: firstly, an aluminum material in a material box (24) falls into an injection tube (3), a screw (5) rotates to push the aluminum material towards a cavity (2), a heating block (4) has an effect of melting the aluminum material, when the rotation speed of the screw (5) is too high, the moving speed of the aluminum material is high, the heating time of the aluminum material by the heating block (4) is shortened, the heating block (4) cannot be completely melted, and the speed of injecting the melted aluminum material into the cavity (2) is high, namely the injection pressure is high, so that an injection product is deformed and cannot be used;
s2: because the connecting shaft (6) is fixedly connected with the screw rod (5), the connecting shaft (6) can rotate along with the screw rod (5), because the outer wall of the connecting shaft (6) is fixedly connected with the connecting spring (8), and one end of the connecting spring (8) far away from the connecting shaft (6) is fixedly connected with the centrifugal block (9), the connecting shaft (6) can drive the centrifugal block (9) to rotate, the centrifugal block (9) rotates to carry out centrifugal motion, the centrifugal block (9) moves towards the direction far away from the connecting shaft (6), the centrifugal block (9) pushes the sliding block (13) to move by utilizing the linkage rod (12), the cylinder (7) and the sliding rail (11) jointly act to play a role in limiting the moving direction of the centrifugal block (9) and the sliding block (13),
s3, the slide block (13) starts to move upwards, the slide block (13) indirectly pushes the clamping rod (15) by the top spring (14), because the outer wall of the clamping rod (15) is provided with a notch which is clamped with the elastic clamping ball (16), when the rotation speed of the screw (5) is enough, the clamping rod (15) can move, because the notch of the clamping rod (15) is divided into a left layer, a middle layer and a right layer, the fixing position is carried out, the clamping rod (15) is prevented from shaking continuously, the screw (5) is caused to change the speed and generate vibration, because the outer wall of the clamping rod (15) is fixedly connected with the ring teeth (25), the clamping rod (15) moves to enable the ring teeth (25) to move rightwards, at the moment, the ring teeth (25) change the contact position with the driving gear (26), because the driving gear (26) is divided into a left layer, a middle layer and a right layer, and the gear density is gradually reduced from left to right, the transmission proportion that the driving gear (26) drives the ring teeth (25) to rotate is reduced, the ring gear (25) is connected with the cylinder (7) through the sliding chute, the ring gear (25) can only move along the direction vertical to the axis of the cylinder (7), so that the ring gear (25) rotates to drive the cylinder (7) to rotate, the outer wall of the connecting shaft (6) is fixedly connected with the cylinder (7), and the outer wall of the connecting shaft (6) is fixedly connected with the screw (5), so that the rotation speed of the cylinder (7), namely the rotation speed of the screw (5), is reduced, namely the injection speed of the aluminum material is reduced, the heating block (4) has enough time to completely melt the aluminum material, and the injection pressure is reduced to avoid the deformation of an injection product;
s4: and because the original injection molding speed is slowed down, the injection speed of the aluminum material in the material box (24) is unchanged, the total amount of the injected aluminum material is reduced, the injection molding product is lack of material, the defect occurs, along with the movement of the sliding block (13), the sliding block (13) can drive the connecting rod (18) to move rightwards, the annular rail (19) plays a role in reducing friction, and because the connecting rod (18) performs circular motion by taking the connecting shaft (6) as the center of a circle, the connecting rod (18) only can extrude the top disc (20) and can not drive the connecting rod (18), under the normal working state, the connecting rod (18) extrudes the top disc (20), the top disc (20) compresses the spring rod (21), at the moment, the connecting rod (18) moves rightwards along with the sliding block (13), the connecting rod (18) can not compress the top disc (20), so the spring rod (21) resets the top disc (20), and the top disc (20) is contacted with the connecting rod (18) again, at the moment, the spring rod (21) integrally moves rightwards, the spring rod (21) drives the gate (23) to move, the flow area of the bottom of the material box (24) is enlarged by the gate (23), the entering speed of the aluminum material is increased, the injection molding speed of the screw (5) in rotation is slowed down, the total amount of the aluminum material which is injected into the cavity (2) in fixed time is unchanged, and the entering amount is maintained to avoid product defects.
