Abstract
This utility model provides a drainage well cover mold that facilitates casting and demolding, relating to the field of hydraulic engineering mold technology. It includes a mold body, with a demolding mechanism both inside and above the mold body. The demolding mechanism includes a mold top cover, the bottom surface of which contacts the upper surface of the mold body. Two sets of guide cylinders are fixedly connected to the inner wall of the mold top cover. A sliding bottom plate is slidably connected inside the mold body, with its bottom surface contacting the inner bottom wall of the mold body. This drainage well cover mold, facilitating casting and demolding, utilizes the sliding bottom plate to slide into the mold body, facilitating the casting of the drainage well cover. A lifting screw, connected to the sliding bottom plate by manually twisting a threaded hole in a positioning block, allows for easy manual gripping and demolding by a demolding hook. This facilitates the lifting of the sliding bottom plate along with the drainage well cover and mold top cover, enabling convenient demolding of the drainage well cover.
