The invention discloses an automatic assembly system for brake shoe iron sheets, which comprises a feeding mechanism for feeding iron sheets; the receiving mechanism is connected with the tail end of the feeding mechanism and used for limiting the stroke of the iron sheet; and the die-casting mechanism comprises a power arm and a gripper, the gripper is provided with a plurality of insert assemblies, and the insert assemblies are used for obtaining the two iron sheets from the material receiving mechanism at the same time. According to the arrangement, iron sheets enter the material receiving structure from the feeding mechanism, the power arm drives the gripper to obtain the iron sheets from the material receiving mechanism, in the process, the insert assembly obtains two iron sheets from the material receiving structure at the same time, the power arm drives the gripper to enter the die casting equipment for die casting, and the two iron sheets are die-cast into a brake shoe at the same time at a time; the die-casting efficiency is improved, the two iron sheets are pressed into the brake shoe at the same time, the die-casting consistency of the two iron sheets is guaranteed, and the rate of finished products is improved. The invention further discloses an automatic assembly method of the brake shoe iron sheet.

This utility model relates to the technical field of steel structure die casting molding device, and discloses a die casting molding device for steel structure production, including a U-shaped bracket, with a support column fixedly connected to the bottom of the inner wall of the U-shaped bracket. By pressing a button, a spring is compressed, causing a limiting block to slide along the inner wall of the second limiting groove, thereby disengaging the limiting rack ring from the limiting rack groove. The rack then enters the interior of the third limiting groove. Rotating the button drives the gear through the limiting rack ring, causing the rack to continue moving inward until the second die casting mold and the first die casting mold are fully in contact. Releasing the button allows the limiting rack ring to re-engage with the button under the action of the spring, firmly fixing the first and second die casting molds together. This prevents molten steel from flowing out of the die casting mold during cooling, affecting the post-die casting performance and avoiding the need for correction of irregular parts after die casting, thus improving die casting efficiency.

This invention discloses a core-pulling type oil pump die-casting mold and its forming method, belonging to the field of die-casting mold technology. During the forming process of the oil pump housing, the main cavity of the oil pump housing is formed by the cooperation of an upper insert block, a lower forming seat, a first protrusion, a second protrusion, and a third protrusion; the pipe section of the oil pump housing is formed by the cooperation of a first core-pulling block and a second core-pulling block; the outer wall surface of the oil pump housing is formed by the cooperation of a front forming block, a left forming block, a right forming block, an upper mold core, and a lower mold core; and the mounting holes of the oil pump housing are formed by the cooperation of the various components. This integrated forming of the oil pump housing not only effectively improves die-casting efficiency and ensures the production efficiency of the oil pump housing, but also, through the reasonable configuration of the size, shape, and position of the mold core, allows for smooth demolding of the oil pump housing, effectively reducing damage to the oil pump housing and ensuring the finished product quality and yield.
