[CN 201721487032.4] Hydraulic press for producing sand-lime brick


[CN 201721487032.4] Title of a hydraulic press for producing lime-sand bricks: Application number of a hydraulic press for producing lime-sand bricks: CN 201721487032.4 Applicant: Chuxiong Henglin Building Materials Co., Ltd. Application date: 2017-11-9 Patent type: Utility model The utility model discloses a hydraulic press for producing lime-sand bricks, including an upper mold seat, a lower mold, a supporting mechanism and a base; A plurality of convex templates parallel to each other are fixedly installed on the lower surface of the upper mold base, the upper surface of the upper mold base is fixedly connected with the ejector rod of the hydraulic system, and the side surface of the upper mold base is fixedly connected with the guide plate. A lower mold is arranged under the multiple convex templates arranged in parallel with each other. The lower mold includes a limit frame, a hook rod, a fixed plate, a concave mold, and a partition, A rubber plate is laid on the upper surface of the supporting mechanism, and the lower mold is placed on the rubber plate. A rubber plate is arranged between the lower mold and the support mechanism. The existence of the rubber plate buffers the pressure between the limit frame and the support mechanism. After the raw materials for the production of lime sand brick are extruded through the convex template in the concave mold, the one-time molding rate of the lime sand brick in the concave mold is higher, and the cavity is less caused by insufficient extrusion of the lime sand brick.
