This invention discloses an electroplating apparatus for ultra-thin PCBs with high and low copper bosses, relating to the field of printed circuit board processing technology. It includes: an electroplating gantry frame with a support rod mounted on it, and a clamping unit for holding and fixing the PCB substrate on the support rod. The clamping unit includes: a fixed frame fixed to the support rod, a connector detachably connected to the fixed frame, two sliding rods slidably connected within the connector, a fixed clamping block fixedly connected to the two sliding rods, a movable clamping block hinged to the fixed clamping block, and a fixed tension spring fixedly connected between the movable clamping block and the connector. This invention uses a substrate to push the fixed and movable clamping blocks together, changing the traction direction of the fixed tension spring on the movable clamping block, thereby keeping the fixed and movable clamping blocks in a clamped or open state. Thus, when fixing and removing the substrate, simply pushing the fixed clamping block with the substrate is sufficient to clamp and remove the substrate, improving operational convenience and reducing the probability of substrate misalignment and wear.

This utility model relates to the field of mold technology and discloses a mold that changes the parting line and ejection angle to solve the problem of product damage during ejection. It includes a front mold and a rear mold, with a cavity formed between them for molding the product. The parting line between the front and rear molds extends downwards to the bottom of one side of the rear mold, changing the original complete contact between the front and rear molds to a large-angle rubbing contact between the front mold and the rear mold. The top of the front mold and the bottom of the moving mold core of the rear mold are contacted. The ejector pins of the front mold, aligned with the easily damaged product position, are flat ejector pins; the ejector pins of the rear mold, also aligned with the easily damaged product position, are flat ejector pins. The parting line is located at the bottom of the rear mold, and the large-angle rubbing design of the front mold solves the problems of uneven force distribution at the edge of the square hole and chamfering during ejection caused by the traditional parting line being in the center. This ensures uniform force distribution on the product during ejection and reduces skewing. The flat ejector pins increase the contact area with the product, reducing unit pressure, and changing the ejection damage marks from "dot-like depressions" to "shallow linear marks" or even no marks, thus avoiding ejection damage.
