[0002] Injection molding, also known as injection molding, is a molding method that combines injection and molding. Injection molded products are accurate in size, fast in production speed and high in efficiency. Therefore, most existing optical lenses are processed by injection molding.

[0054] Referring to Figures 1-7 The bottom mounting frame 21 and the supporting tray 211 are both provided with notches 2111; and the rack 1 is installed with a movement control assembly 22 used for driving the bottom mounting frame 21 to move along the horizontal direction or the vertical direction.

[0055] The application avoids the collision between the bottom mounting frame 21, the supporting tray 211 and the first top pin 111 by the gap 2111 and the movement control assembly 22, automatically fixes the supporting tray 211 by the movement control assembly 22, and improves the deburring efficiency of the resin lens 6; the movement control assembly 22 is electrically connected with the controller; the operator first completes the injection molding processing of the resin lens 6 through the cooperation of the fixed mold 11 and the movable mold 12, then drives the first top pin 111 and the movable mold 12 to move upward synchronously through the first linear driver 112 and the third linear driver 13 respectively until the resin lens 6 moves to the bottom mounting frame 21, then drives the bottom mounting frame 21 to move along the horizontal direction through the movement control assembly 22 until the axis of the supporting tray 211 is collinear with the axis of the resin lens 6, then drives the bottom mounting frame 21 and the second top pin 121 to move downward along the vertical direction through the movement control assembly 22 and the second linear driver 122 respectively until the supporting tray 211 abuts against the resin lens 6, and the resin lens 6 is separated from the movable mold 12 at the same time, then controls the movable mold 12 to continue to move upward through the third linear driver 13, at this time, the operator drives the resin lens 6 to rotate through the top driving device 3 to deburr the resin lens 6; the gap 2111 is arranged on the bottom mounting frame 21 and the supporting tray 211 to avoid the collision with the first top pin 111, so that the deburring step can be optimized, the resin lens 6 is clamped and driven to rotate by the bottom supporting device 2 and the top driving device 3 without being taken off, the burrs are removed by the cutting device 4, the processing efficiency is greatly improved while the quality of the resin lens 6 is ensured.

[0056] With reference to Figure 4 And Figure 5 The lens injection molding equipment further comprises a positioning device 5, the positioning device 5 comprises a locking assembly 51 and a rotation control assembly 52; the locking assembly 51 is installed on the bottom mounting frame 21, and the locking assembly 51 is used for fixing the supporting tray 211; the rotation control assembly 52 is used for controlling the rotation of the supporting tray 211.

[0057] The present application realizes the function of limiting the self-rotation of the bearing tray 211 through the locking assembly 51 and the rotation control assembly 52, and achieves the effect of preventing the bearing tray from colliding with the first thimble 111 due to self-rotation. Since the bearing tray and the bottom mounting frame 21 are both provided with the notch 2111, and the bearing tray 211 is rotatably installed on the bottom mounting frame 21, once the bearing tray is self-rotated under the action of external force, the notch 2111 of the bearing tray will be misaligned with the notch 2111 on the bottom mounting frame 21, and the bearing tray will collide with the first thimble 111 during cooperation with the resin lens 6. Therefore, the rotation control assembly 52 and the locking assembly 51 are designed to limit the rotation of the bearing tray 211. Before the bearing tray 211 cooperates with the resin lens 6, the bearing tray 211 is fixed through the locking assembly 51, and after the bearing tray 211 cooperates with the resin lens 6, the fixing of the locking assembly 51 is released through the rotation control assembly 52, so that the bearing tray 211 can rotate synchronously with the resin lens 6.

[0058] With reference to Figures 3-6 : The locking assembly 51 comprises a locking block 511, which is slidingly installed on the bottom mounting frame 21. The bearing tray 211 is provided with a positioning groove 512 matched with the locking block 511. The bearing tray 211 is also provided with an annular track 513 located above the positioning groove 512.

[0059] The present application realizes the function of quickly fixing the bearing tray 211 through the locking block 511, the positioning groove 512 and the annular track 513. In the non-working state of the bearing tray 211, the locking block 511 cooperates with the positioning groove 512 to limit the rotation of the bearing tray 211 through the locking block 511, so as to avoid the misalignment of the notches 2111 on the bearing tray 211 and the bottom mounting frame 21. After the bearing tray 211 cooperates with the resin lens 6, the operator drives the locking block 511 to separate it from the positioning groove 512 and match it with the annular track 513, so that the bearing tray 211 can rotate synchronously with the resin lens 6.

[0060] With reference to Figure 3 、 Figure 4 、 Figure 5 and Figure 7 : The rotation control assembly 52 comprises a gasket 522 and a first elastic member 523. The bottom mounting frame 21 is provided with a sliding rail 521, and the bearing tray 211 slidingly cooperates with the sliding rail 521. The gasket 522 is slidingly installed in the sliding rail 521, and the bearing tray 211 slidingly cooperates with the gasket 522. The two ends of the first elastic member 523 are fixedly connected with the bottom mounting frame 21 and the gasket 522, respectively.

[0061] The present application realizes the function of quickly releasing the rotation restriction of the supporting tray 211 by the locking block 511 by the extrusion of the resin lens 6 to the supporting tray 211 through the sliding rail 521, the gasket 522 and the first elastic member 523; the supporting shaft 524 is fixedly installed at the bottom of the supporting tray 211 and is in sliding fit with the gasket 522; in the non-working state, the locking block 511 is matched with the positioning groove 512 to limit the rotation of the supporting tray 211, and after the supporting tray 211 is matched with the resin lens 6, the upper end of the resin lens 6 is fixed by the top driving device 3, then the controller sends a signal to the moving control assembly 22, the moving control assembly 22 drives the bottom mounting frame 21 to move upward, so that the extrusion between the bottom mounting frame 21 and the supporting tray 211 occurs, the first elastic member 523 is contracted after being pressed, the bottom mounting frame 21 moves upward relative to the supporting tray 211, the bottom mounting frame 21 drives the locking block 511 to move upward, and the rotation restriction of the supporting tray 211 is released, so that the processing steps are further simplified, and the manual sliding of the locking block 511 by the operator is not needed.

[0062] With reference to Figures 3-8 The positioning device 5 further comprises a reset assembly 53, the reset assembly 53 comprising a mounting seat 531, a pressure sensor 533 and a second elastic member 534; the mounting seat 531 is fixedly installed on the bottom mounting frame 21, and the locking block 511 is slidingly installed on the mounting seat 531; the locking block 511 is provided with an inclined surface 532; the pressure sensor 533 is fixedly installed on the mounting seat 531; and the two ends of the second elastic member 534 are fixedly connected with the pressure sensor 533 and the locking block 511 respectively.

[0063] The application realizes the function of automatically controlling the reset of the supporting tray 211 after deburring by the mounting seat 531, the inclined surface 532, the pressure sensor 533 and the second elastic piece 534; since the supporting tray 211 and the bottom mounting frame 21 are both provided with the notch 2111, in order to avoid the misplacement of the notch 2111 of the two, the locking assembly 51 and the rotation control assembly 52 are arranged, but after the processing is completed, in order to facilitate the subsequent processing of the supporting tray 211, the operator needs to adjust the position thereof by himself and fix it through the locking assembly 51, which affects the processing efficiency; therefore, the reset assembly 53 is designed, after the processing is completed, the operator drives the bottom mounting frame 21 to move downward through the movement control assembly 22, since the weight of the resin lens 6 is small, the supporting tray 211 falls under the resin lens 6 under the action of the first elastic piece 523, so that the locking block 511 moves to the lower side of the annular track 513, if the position of the supporting tray 211 deviates from the initial position, the locking block 511 is extruded by the supporting tray 211, the second elastic piece 534 is extruded, the pressure sensor 533 feeds back the signal to the controller, the controller can judge the state of the supporting tray 211, and then the controller sends the signal to the top driving device 3, the top driving device 3 drives the resin lens 6 to rotate slowly, the resin lens 6 drives the supporting tray 211 to rotate, with the rotation of the supporting tray 211, until the locking block 511 moves to the positioning groove 512, so that the supporting tray 211 returns to the initial position, and the supporting tray 211 is fixed through the positioning groove 512.

[0064] Referring to Figures 3-8 The transition slide 535 is arranged on the supporting tray 211 and is located below the annular track 513.
