Description

Technical Field

[0001] This utility model belongs to the field of mold technology, specifically relating to a surface texture manufacturing device for a shell injection mold. Background Technology

[0002] In the mold manufacturing industry, surface texturing of injection mold shells is one of the key processes. Traditionally, the hoisting and positioning of mold steel is usually performed directly on the machining table. However, this direct hoisting method has significant drawbacks, mainly in the following aspects:

[0003] The clamping device is susceptible to impact. When hoisting mold steel, due to its large weight, the impact force during the hoisting process may damage the mechanical components of the clamping device. For example, the clamping claws may deform or loosen when subjected to accidental impact, directly affecting the clamping accuracy and stability, and thus affecting the processing quality of texture manufacturing. The optical components are also fragile. Mold surface texture manufacturing usually relies on optical technologies such as laser engraving. Optical components (such as laser emitters and focusing lenses) are extremely sensitive to vibration and impact. During hoisting, collisions with the mold steel may cause displacement or damage to the optical components, leading to a decrease in processing accuracy and even requiring frequent replacement or repair of optical components, increasing production costs and reducing processing efficiency. Traditional hoisting methods require manual intervention, which is complex and time-consuming. The positioning and clamping process of mold steel often relies on manual operation, which not only increases labor intensity but may also lead to a longer processing cycle, affecting overall production efficiency. Equipment maintenance costs are high. Because the clamping device and optical components are easily damaged by impact, the frequency and cost of equipment maintenance increase significantly. Frequent repairs and replacements of parts not only waste resources but also lead to longer equipment downtime, further affecting production efficiency. Utility Model Content

[0024] An apparatus for manufacturing surface textures for a housing injection mold, comprising,

[0025] Workbench 1;

[0026] The feeding clamping assembly is located on the outer wall of the workbench 1. The feeding clamping assembly includes a slide rail 3, a drag-reducing wheel 301, a clamping platform 4, a lifting frame 501, a clamping claw 8, a protective shell 9, a driven gear 10, a drive gear 14, a rack 15, and a drive assembly. The drag-reducing wheel 301 is rotatably inserted into the slot in the inner wall of the slide rail 3. The clamping platform 4 is fixedly installed at the top of the outer wall of the lifting frame 501.

[0027] In a specific embodiment of this utility model, the feeding and clamping assembly achieves automatic conveying, lifting, and positioning of mold steel through the coordinated operation of the trolley 2, the feeding cylinder 6, and the lifting cylinder 5, reducing manual intervention and improving processing efficiency.

[0036] Specifically, mounting rails 101 are fixedly installed on both sides of the top of the outer wall of the workbench 1, and the mounting rails 101 are embedded in the inner wall of the slide rail 3. A trolley 2 is snapped onto one side of the outer wall of the workbench 1, and a constraint frame 201 is slidably inserted into the top of the outer wall of the trolley 2. A feeding cylinder 6 is fixedly installed at the bottom of the inner wall of the trolley 2, and an ejector rod 7 is fixedly installed at the output end of the feeding cylinder 6.

[0037] In a specific embodiment of this utility model, the ejector rod 7 is slidably inserted into the slot at the top of the outer wall of the trolley 2, which can ensure that interference from the ejector rod 7 is avoided.

[0038] Working principle:

[0039] Using hoisting equipment, the mold steel to be processed is lifted onto the top of the trolley 2 and initially fixed by the sliding constraint frame 201 on the trolley 2 to ensure the stability of the mold steel during transportation. The trolley 2 is moved to the outside of the workbench 1, and the trolley 2 is aligned with the workbench 1 by a snap-fit ​​structure to ensure that the ejector rod 7 matches the entrance position of the slide rail 3. The constraint frame 201 on the trolley 2 is released from fixing the mold steel. The feeding cylinder 6 at the bottom of the trolley 2 is activated to drive the ejector rod 7 to lift upward, smoothly lifting the mold steel from the top of the trolley 2 to the entrance of the slide rail 3. With the assistance of the drag-reducing wheel 301, the mold steel moves along the inner wall of the slide rail 3. The slide rail 3 is tightly fitted with the mounting rail 101 of the workbench 1 to ensure that the mold steel slides accurately to the position directly above the clamping platform 4. The lifting cylinder 5 at the bottom of the workbench 1 is activated to drive the lifting frame 501 to rise, so that the clamping platform 4 contacts the mold steel, completing the vertical positioning. The clamping motor 11 is started, and the active bevel gear 12 and the driven bevel gear... 13 meshing transmission drives the gear 14 to rotate, causing the racks 15 on both sides to move synchronously in opposite directions. The racks 15 mesh with the driven gears 10 at the ends of the clamping claws 8, causing the two clamping claws 8 to close symmetrically inward, thus completing the stable clamping of the mold steel. The protective shell 9 outside the clamping claws 8 covers the key transmission components to prevent damage to the gears and racks 15 from splashes during laser engraving. After clamping, the laser texture manufacturing table on the top of the worktable 1 is activated, and high-precision texture engraving is performed on the surface of the mold steel according to the preset program. The lifting frame 501 and the worktable 1 are designed to slide and fit together. With the uniform clamping force of the clamping claws 8, the mold steel is ensured to have no displacement or vibration during processing. After processing, the clamping motor 11 drives in the reverse direction, the racks 15 retract, the clamping claws 8 release the mold steel, the lifting cylinder 5 retracts, and the lifting frame 501 descends to the initial position. The mold steel falls back into the slide rail 3 and slides in the reverse direction along the slide rail 3 to the top of the trolley 2, where it is re-fixed by the constraint frame 201, completing the unloading.
