Description

A mold for forming an optical module base Technical Field

[0001] This utility model relates to the field of molding die technology, and specifically to a molding die for an optical module base. Background Technology

[0002] As a key component that carries the optical devices, circuit chips and fiber optic interfaces inside the optical module, the optical module base needs to balance precision, heat dissipation, electromagnetic shielding and cost in its processing and production methods. Among them, the main processing methods for metal bases include die casting and sheet metal stamping.

[0003] According to the public announcement (CN221869871U), an aluminum profile stamping forming device is disclosed. This technology discloses "a base, vertical plates fixed at the four corners of the upper surface of the base, and horizontal plates fixed at the ends of the vertical plates away from the base. A worktable is provided above the base, and clamping components are symmetrically installed on both sides of the upper surface of the worktable. The device has the following technical effects: the clamping components can clamp and fix the aluminum profile, preventing displacement of the aluminum profile during the stamping forming process, preventing deviation of the stamping position of the aluminum profile, improving the stamping forming quality and efficiency of the aluminum profile; the buffer components can buffer the impact force on the moving plate, improving the stamping forming effect of the aluminum profile, while preventing damage to the stamping head and fixed die from excessive impact force, increasing service life; the stamping components can limit the movement of the stamping head, thereby improving the stamping forming accuracy of the aluminum profile."

[0004] However, in the process of stamping the sheet metal of the optical module base molding die, manual loading and unloading are often used, which can lead to safety hazards. Compared with the stamping structure mentioned above, no effective safety solution has been proposed for loading and unloading.

[0005] To address the aforementioned issues, this application proposes a molding die for an optical module base. Summary of the Invention

[0006] This utility model addresses the technical problems existing in the prior art by providing a molding die for an optical module base.

[0007] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A mold for forming an optical module base includes a bracket, a motor is fixedly connected to the inner wall of the bracket, a lower mold is fixedly connected to the output end of the motor, a locking block is fixedly connected to the upper part of the lower mold, a rotating seat is fixedly connected to the inner wall of the bracket, the surface of the rotating seat is rotatably connected to the lower mold, a cylinder is fixedly connected to the upper part of the bracket, an upper mold is fixedly connected to the output end of the cylinder, and a feeding mechanism is provided on the side end of the bracket.

[0008] The feeding mechanism includes a shelf fixedly connected to the side of the support, a slide fixedly connected to the upper part of the shelf, a first pulley fixedly connected to the side end of the slide, a second pulley fixedly connected to the top of the inner wall of the support, a rope fixedly connected to the upper part of the upper mold, a slide plate slidably connected to the inner wall of the slide, the end of the rope fixedly connected to the slide plate, the surface of the rope rollingly connected to the first pulley and the second pulley respectively, and a push rod fixedly connected to the side end of the slide plate. The mechanism is designed so that when the upper mold descends, the push rod can be driven by the rope to move towards the lower mold.

[0009] The surface of the shelf is provided with a sliding groove, and a guide rod is slidably connected to the shelf through the sliding groove. The side end of the guide rod is fixedly connected to the slide plate, and the side end of the slide plate is fixedly connected to a first spring. The fixed end of the first spring is fixedly connected to the shelf. By means of the arrangement, when the upper mold moves upward, the slide plate can drive the push rod to return to its original position under the constraint of the first spring.

[0010] The lower mold is provided with a demolding mechanism at its upper part. The demolding mechanism includes a top plate slidably connected inside the lower mold, a push rod fixedly connected to the upper part of the top plate, a second spring fixedly connected to the upper part of the top plate, the fixed end of the second spring fixedly connected to the lower mold, a push block fixedly connected to the lower part of the top plate, and a tapered rotating shaft fixedly connected to the surface of the rotating base. The surface of the tapered rotating shaft is slidably connected to the push block. By setting the mechanism so that after the lower mold rotates, it pushes the push block through the tapered rotating shaft, and the push rod moves outward to push out the optical module base, thereby assisting in enhancing the demolding effect.

[0011] The beneficial effects of this utility model are: by placing the sheet metal on the feeding mechanism, the automatic feeding operation is achieved by linking the upper mold and the feeding mechanism, and after stamping, the lower mold is driven by the motor to achieve the automatic unloading function, thus avoiding the dangerous operation of manually inserting the material into the mold.

[0012] After the lower mold rotates, the cone surface of the tapered shaft pushes the push block, causing the top plate to move the push rod outward, thereby pushing out the optical module base. This helps to enhance the demolding effect and avoids the base remaining stuck inside the lower mold. Attached Figure Description

[0024] Referring to Figures 1 and 2, a mold for forming a light module base includes a bracket 1. A motor 2 is fixedly connected to the inner wall of the bracket 1. A lower mold 3 is fixedly connected to the output end of the motor 2. A locking block 4 is fixedly connected to the upper part of the lower mold 3. A rotating seat 5 is fixedly connected to the inner wall of the bracket 1. The surface of the rotating seat 5 is rotatably connected to the lower mold 3. The outer circumference of the rotating seat 5 at this point is equal to the inner circumference of the lower mold 3 at this point. A cylinder 6 is fixedly connected to the upper part of the bracket 1. An upper mold 7 is fixedly connected to the output end of the cylinder 6. A feeding mechanism 8 is provided on the side end of the bracket 1. The sheet metal is placed on the feeding mechanism 8. Automatic feeding operation is achieved through the linkage of the upper mold 7 and the feeding mechanism 8. After stamping, the lower mold 3 is driven by the motor 2 to achieve automatic unloading.

[0025] Referring to Figures 1-3, the feeding mechanism 8 includes a shelf 801 fixedly connected to the side of the support 1. A slide 802 is fixedly connected to the upper part of the shelf 801. Two slides 802 are provided. A first pulley 803 is fixedly connected to the side end of the slide 802. A second pulley 804 is fixedly connected to the top of the inner wall of the support 1. Two first pulleys 803 and two second pulleys 804 are provided respectively. A rope 805 is fixedly connected to the upper part of the upper mold 7. A sliding plate 806 is slidably connected to the inner wall of the slide 802. The end of the rope 805 is connected to the sliding plate 806. 6. Fixed connection: Two ropes 805 are provided to balance the force on the slide plate 806. The surfaces of the ropes 805 are rolled between the first pulley 803 and the second pulley 804 respectively. A push rod 807 is fixedly connected to the side end of the slide plate 806. By setting it up, when the upper mold 7 descends, it pulls the ropes 805 downwards. Under the action of the first pulley 803 and the second pulley 804, the ropes 805 change the direction of the force, so that the push rod 807 on the slide plate 806 pushes the plate to the top of the lower mold 3 and inserts into the locking block 4 for fixation.

[0026] Referring to Figures 1-3, a sliding groove 808 is provided on the surface of the shelf 801. A guide rod 809 is slidably connected to the shelf 801 through the sliding groove 808. There are two guide rods 809. The side end of the guide rod 809 is fixedly connected to the slide plate 806. The side end of the slide plate 806 is fixedly connected to the first spring 810. The fixed end of the first spring 810 is fixedly connected to the shelf 801. By setting it up so that when the upper mold 7 moves upward, the slide plate 806 can drive the push rod 807 to return to its original position under the constraint of the first spring 810, thereby facilitating the subsequent placement of the board in front of the push rod 807.

[0027] Referring to Figures 1-4, a demolding mechanism 9 is provided on the upper part of the lower mold 3. The demolding mechanism 9 includes a top plate 901 slidably connected inside the lower mold 3, a push rod 902 fixedly connected to the upper part of the top plate 901, a second spring 903 fixedly connected to the upper part of the top plate 901, and the fixed end of the second spring 903 fixedly connected to the lower mold 3. Two push blocks 904 are fixedly connected to the lower part of the top plate 901. A tapered rotating shaft 905 is fixedly connected to the surface of the rotating base 5. There are two shafts 905. The surface of the tapered rotating shaft 905 is slidably connected to the push block 904. By setting it up, the lower mold 3 can rotate. The shape of the tapered rotating shaft 905 is half circular and half conical. When the lower mold 3 rotates more than 90°, the push block 904 will be pushed up by the tapered rotating shaft 905, which will drive the push rod 902 to move upward and push out the optical module base. After the angle is reset, the top plate 901 will be reset under the pull of the second spring 903, thereby enhancing the demolding effect of the mold.

[0028] Working principle:

[0029] The optical module base forming mold places the plate at the front end of the push rod 807. The cylinder 6 is activated to drive the upper mold 7 to descend. The upper mold 7 pulls the rope 805 downward. The rope 805 changes the direction of force under the action of the first pulley 803 and the second pulley 804, so that the push rod 807 on the slide plate 806 pushes the plate to the top of the lower mold 3 and inserts into the locking block 4 for fixation. When the upper mold 7 moves upward, the slide plate 806 can drive the push rod 807 to reset under the constraint of the first spring 810, so that the plate can be placed in front of the push rod 807 in the future. After the optical module base is stamped, the motor 2 is started to rotate in the direction of the shelf 801 to achieve the demolding effect.

[0030] When the lower mold 3 rotates more than 90°, the push block 904 will be lifted by the tapered rotating shaft 905, thereby driving the push rod 902 to move upward and push out the optical module base. After the angle is reset, the top plate 901 will be reset under the pull of the second spring 903, thereby enhancing the demolding effect of the mold and preventing the base from getting stuck inside the mold.
