An injection molding device for completely molding and demolding aluminum materials, and an injection molding method of the injection molding device comprises the following specific steps:
S1: firstly, aluminum materials in a material box fall into an injection tube, the screw rotates to push the aluminum materials to the direction of a cavity, a heating block has the effect of melting the aluminum materials, when the rotating speed of the screw is too high, the moving speed of the aluminum materials is high, the time of the aluminum materials heated by the heating block is shortened, the heating block cannot be completely melted, and the melted aluminum materials are injected into the cavity at the moment at a high speed, namely, the injection pressure is high, so that an injection molding product is deformed and cannot be used;
S2: because the connecting shaft is fixedly connected with the screw rod, the connecting shaft can rotate along with the screw rod, and because the outer wall of the connecting shaft is fixedly connected with the connecting spring, and one end of the connecting spring, which is far away from the connecting shaft, is fixedly connected with the centrifugal block, the connecting shaft can drive the centrifugal block to rotate, the centrifugal block rotates to perform centrifugal motion, the centrifugal block moves in a direction far away from the connecting shaft, the centrifugal block pushes the sliding block to move by utilizing the linkage rod, and the cylinder and the sliding rail act together to play a role in limiting the moving direction of the centrifugal block and the sliding block;
S3, the sliding block 13 starts to move upwards, the sliding block indirectly pushes the clamping rod by utilizing the top spring, the notch is formed in the outer wall of the clamping rod and is clamped with the elastic clamping ball, so that when the rotating speed of the screw rod is enough, the clamping rod can move, the notch of the clamping rod is divided into a left layer, a middle layer and a right layer for fixing positions, the continuous shaking of the clamping rod is avoided, the screw rod is caused to continuously change the speed to vibrate, the outer wall of the clamping rod is fixedly connected with the annular tooth, the clamping rod moves to enable the annular tooth to move rightwards, at the moment, the annular tooth changes the contact position with the driving gear, the driving gear is divided into the left layer, the middle layer and the right layer, the gear density of the driving gear is gradually reduced, the driving gear drives the annular tooth to rotate, the annular tooth is connected with the cylinder through the sliding groove, the annular tooth can only move along the direction vertical to the axis of the cylinder, at the moment, the outer wall of the connecting shaft is fixedly connected with the screw rod, the rotating speed of the cylinder is lower, the rotating speed of the screw rod is reduced, namely the injection block has enough time to reduce the heating speed, the injection block of the injection molding material is completely deformed, and injection molding of the injection molding material is completely avoided;
S4: and because original injection molding speed slows down, the inside aluminium material injection speed of material case is unchangeable, its total volume of injection aluminium material that gets into becomes fewer, can lead to injection molding product lack material, the incomplete appears, along with the slider removes, the slider can drive the connecting rod and move rightwards, the annular rail plays the effect of reducing friction, and because the connecting rod is taking the connecting axle as the centre of a circle to carry out circular motion, the connecting rod can only extrude the roof dish, can not drive the connecting rod, under the normal operating condition, the connecting rod extrudees the roof dish, the roof dish compression spring rod, and the connecting rod moves rightwards along with the slider at this moment, the connecting rod no longer compresses the roof dish, so the spring rod resets the roof dish, the roof dish contacts with the connecting rod again, be located the spring rod and wholly remove rightwards at this moment, the spring rod drives the gate and removes, the gate enlarges the flow area of material case bottom, increase aluminium material's entering speed, and the rotatory injection molding speed of screw rod slows down, make the inside aluminium material total volume of injection molding in the fixed time not change, keep entering quantity and avoid the incomplete product.
Compared with the prior art, the invention has the following beneficial effects:
1. This injection molding equipment and injection molding method that aluminium material injection pressure control avoids deformation, through at first, inside aluminium material of material case falls into the inside of injection syringe, the screw rod is rotatory to the direction lapse of die cavity with aluminium material, rotational speed when the screw rod is too fast, the connecting axle can drive the centrifugal piece and rotate, centrifugal piece rotatory centrifugal motion carries out, centrifugal piece moves towards the direction of keeping away from the connecting axle, the centrifugal piece utilizes the gangbar to promote the slider removal, cylinder and sliding rail coaction play the effect of restriction centrifugal piece and slider direction of movement, the slider begins upwards to move, the slider utilizes top spring indirect thrust joint pole, because the notch has been seted up to the outer wall of joint pole, and notch and elasticity joint ball, so when the rotational speed of screw rod is enough, just can make the joint pole remove, because the notch of joint pole divide into the left and right three-layer, carry out fixed position, avoid the joint pole to shake constantly, the continuous speed of change of screw rod produces the vibration, because the outer wall and the ring tooth fixed connection of joint pole remove makes the ring tooth remove right, ring tooth change its and drive gear contact position, because the drive gear divide into left and right three-layer, and its gear gradually moves upwards, the gear wheel tooth indirectly passes through the joint pole, the notch, because the notch has notch and elastic joint ball joint, the aluminium material reduces the rotational speed, the injection molding material can be made to move, the joint rod, the reduction, the injection molding time is reduced, the complete deformation, the injection molding material is reduced, and the injection molding speed is realized.
2. According to the injection molding equipment and the injection molding method for preventing deformation by controlling the injection pressure of the aluminum material, the original injection molding speed is reduced, the injection speed of the aluminum material inside the material box is unchanged, the total quantity of the injected aluminum material is reduced, the injection molding product lacks materials, defects appear, the sliding block drives the connecting rod to move rightwards along with the sliding block, the annular rail has the effect of reducing friction, the connecting rod only extrudes the top disc and does not drive the connecting rod because the connecting rod performs circular motion by taking the connecting shaft as a circle center, the top disc compresses the spring rod, the connecting rod moves rightwards along with the sliding block at the moment, the connecting rod does not compress the top disc any more, the spring rod resets the top disc, the top disc is contacted with the connecting rod again, the spring rod is integrally moved rightwards at the moment, the spring rod drives the gate to move, the flow area at the bottom of the material box is enlarged, the entering speed of the aluminum material is increased, and the injection molding speed of the rotation of the screw rod is reduced, so that the total quantity of the aluminum material injected into the cavity is unchanged in the fixed time, and the defect of the product is prevented.
