Abstract
Description
Technical Field
[0001] This utility model relates to the field of molding die technology, specifically to an anti-displacement sand core molding die. Background Technology
[0002] Sand cores are materials used in casting production to manufacture mold cores. They are composed of casting sand, molding sand binders, and additives mixed in a certain proportion. The mold core is mostly surrounded by high-temperature molten metal in the mold, while the supporting and positioning parts are generally small in size. Therefore, in addition to possessing the properties of general molding sand, core sand also requires high strength, permeability, collapsibility, and disintegration properties. Core sand is classified according to the binder used, such as clay core sand, water glass core sand, and oil core sand.
[0003] However, in the existing technology, the existing mold manufacturing requires sand core forming mold groove. However, the fit between the upper mold and the lower mold cannot be misaligned or offset. If the upper mold and the lower mold are misaligned, it will easily lead to quality problems in the mold manufacturing process. At the same time, the mold needs heat dissipation during the manufacturing process to speed up the forming efficiency.
[0004] Therefore, we need an anti-displacement sand core forming mold to solve the problem of anti-displacement of existing sand core forming molds, and also to achieve heat dissipation effect for sand core forming molds. Utility Model Content
[0005] The purpose of this utility model is to provide an anti-displacement sand core forming mold to solve the problem of anti-displacement of existing sand core forming molds mentioned in the background art, and also to achieve the heat dissipation effect of sand core forming molds.
[0006] To achieve the above objectives, this utility model provides the following technical solution: an anti-deviation sand core forming mold, comprising an operating table, the top surface of which is fixedly connected to the bottom surface of a support frame, a guide rod fixedly connected to the inner top surface of the support frame, the bottom end of the guide rod fixedly connected to the top surface of the operating table, the surface of the guide rod movably connected to the surface of a through hole, the through hole being located on the top surface of a lifting plate, a return spring being provided on the surface of the guide rod, an upper mold fixedly connected to the bottom surface of the lifting plate, the surface of the upper mold movably connected to the interior of a lower mold, the surface of the lower mold movably connected to the surface of a lower mold groove, the lower mold groove being located inside the operating table, the top surface of the lifting plate fixedly connected to the end of the power output shaft of a hydraulic cylinder, and the base of the hydraulic cylinder fixedly connected to the inner top surface of the support frame.
[0007] Preferably, the bottom surface of the lifting plate is provided with an integrally formed positioning rod, the surface of the positioning rod is movably connected to the surface of the positioning groove, and the positioning groove is provided on the top surface of the heat exchange box.
[0008] Preferably, the bottom radius of the positioning rod is equal to the radius of the positioning groove, the height of the positioning rod is equal to the depth of the positioning groove, and there are two positioning grooves, which are symmetrically arranged along the center point of the heat exchange box.
[0009] Preferably, the top surface of the operating table is fixedly connected to an installation rod, the surface of the installation rod is movably connected to the surface of the installation groove, the installation groove is opened on the bottom surface of the heat exchange box, the depth of the installation groove is equal to the height of the installation rod, the radius of the top surface of the installation rod is equal to the radius of the installation groove, and there are two installation grooves, which are symmetrically arranged along the center point of the heat exchange box.
[0010] Preferably, the heat exchange box has a heat conduction cavity inside, which is connected to the vent. The vent is located on the side surface of the heat exchange box and is square in shape. There are two vents, which are symmetrically arranged around the center point of the heat exchange box.
[0011] Preferably, the top surface of the heat exchange box is provided with a groove, and the cross-section of the groove on the top surface of the heat exchange box is set in an "L" shape.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: By movably connecting the surface of the through hole to the surface of the guide rod, the lifting plate can drive the upper mold to move steadily along the surface of the guide rod on the top surface of the operating table. By movably connecting the surface of the lower mold to the surface of the lower mold groove, the lower mold can be steadily installed inside the heat exchange box, preventing the upper mold from shifting when inserted into the lower mold. When the lifting plate moves downward, the positioning rod is inserted into the surface of the positioning groove, so that the lifting plate can be steadily placed on the top surface of the heat exchange box, and the heat exchange box can be steadily installed on the top surface of the operating table. When the heat exchange box is removed from the top surface of the operating table, it is convenient to replace the lower mold inside the heat exchange box. The surface of the lower mold is fixedly connected to the surface of the lower mold groove. When the mold is formed inside the lower mold, the airflow can flow between the heat conduction cavity and the vent, thereby achieving a heat dissipation effect on the mold inside the lower mold. This further solves the problem of preventing the existing sand core forming mold from shifting and can also achieve a heat dissipation effect on the sand core forming mold.
