Abstract
Description
Technical Field
[0001] This utility model relates to the field of casting molds, specifically to a casting mold for a motorcycle main pump blank. Background Technology
[0002] Currently, motorcycle hydraulic brake pumps, due to their unique shape, require specialized casting molds for manufacturing. The inner cavity of the oil cup in a motorcycle hydraulic brake pump is rectangular, necessitating casting onto a mold. Existing casting molds make removing the casting difficult and inefficient. Utility Model Content
[0003] The purpose of this utility model is to address the above-mentioned shortcomings by providing a casting mold for a motorcycle main pump blank.
[0004] This utility model includes a lower mold, an upper mold, and a core-pulling block. The lower mold has a contoured lower groove at the top, with a pouring port at one end and a core-pulling lower groove at the other end. The upper mold has a contoured upper groove at the bottom, with a pouring port at one end and a core-pulling upper groove at the other end. After the lower and upper molds are closed, the contoured lower groove and the contoured upper groove are coupled, and the core-pulling block is inserted into the core-pulling lower groove and the core-pulling upper groove.
[0005] The core-pulling block consists of a rectangular positioning block and an inner cavity forming block, with the end of the inner cavity forming block being a V-shaped inner cavity contour head.
[0006] The rectangular positioning block is coupled to the inner walls of the lower and upper core-pulling slots.
[0007] The casting ports of the lower and upper contoured grooves are combined to form a cylindrical casting port.
[0008] The bottom four corners of the upper mold are provided with mold opening grooves.
[0009] Both the lower and upper molds are rectangular molds.
[0010] The advantages of this invention are: fast casting speed, and after casting is completed, the core block can be directly pulled out after the mold is opened, so that the casting can be taken out, resulting in high production efficiency. Attached Figure Description

[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.
[0020] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.
[0021] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0022] In the description of the embodiments of this invention, it should be noted that if terms such as "upper," "lower," "inner," or "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product is in use, they are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. Furthermore, if terms such as "first" or "second" appear in the description of this invention, they are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.
[0023] In the description of the embodiments of the present invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the present invention based on the specific circumstances.
[0024] As shown in the attached diagram, this utility model includes a lower mold 1, an upper mold 2, and a core-pulling block 3. The lower mold 1 has a contoured lower groove 4 at the top, one end of which is the pouring port, and the other end of which is the core-pulling lower groove 5. The upper mold 2 has a contoured upper groove 6 at the bottom, one end of which is the pouring port, and the other end of which is the core-pulling upper groove 7. After the lower mold 1 and the upper mold 2 are closed, the contoured lower groove 4 and the contoured upper groove 6 are coupled, and the core-pulling block 3 is inserted into the core-pulling lower groove 5 and the core-pulling upper groove 7.
[0025] The core-pulling block 3 consists of a rectangular positioning block 8 and an inner cavity forming block 9. The end of the inner cavity forming block 9 is a V-shaped inner cavity contour head.
[0026] The rectangular positioning block 8 is coupled to the inner walls of the lower core-pulling groove 5 and the upper core-pulling groove 7.
[0027] The casting ports of the lower contoured groove 4 and the upper contoured groove 6 are combined to form a cylindrical casting port.
[0028] The upper mold 2 has opening grooves 10 at its four bottom corners. The opening grooves 10 facilitate the opening of the upper mold 2.
[0029] Both the lower mold 1 and the upper mold 2 are rectangular molds.
[0030] Example 1: The upper mold 2 and lower mold 1 are closed. The core-pulling block 3 is inserted into the lower core-pulling groove 5 and the upper core-pulling groove 7. The molten metal is poured into the pouring port, filling the lower contour groove 4 and the upper contour groove 6. After cooling and solidification, the upper mold 2 is opened, the core-pulling block 3 is pulled out, and the motorcycle main pump blank 100 can be removed. The cylindrical casting pre-reserved portion on the motorcycle main pump blank 100 is cut off, and subsequent finishing can be performed. The inner cavity forming block 9 is used to form the inner cavity of the oil cup. The rectangular positioning block 8, while positioning the casting position, blocks the lower core-pulling groove 5 and the upper core-pulling groove 7 to prevent molten metal from seeping out.
