Description

Technical Field

[0001] This utility model relates to the field of home appliance mold technology, specifically to a precision home appliance mold. Background Technology

[0002] Household appliances (HEA) mainly refer to various electrical and electronic appliances used in homes and similar places. They are also known as household appliances or daily appliances. Household appliances liberate people from heavy, tedious, and time-consuming housework, creating a more comfortable, beautiful, and healthier living and working environment, and providing a wealth of cultural and entertainment options. They have become necessities for modern family life.

[0003] Whether small or large, household appliances are all powered on. Over time, they will generate heat and affect their lifespan. Therefore, heat dissipation is a crucial attribute of household appliances. Heat dissipation covers are usually used in motors or core areas to ensure good ventilation for fans and achieve heat dissipation. Molds are needed to process these covers. Generally, molds only have the function of casting and shaping, and their effect is limited. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a precision household appliance mold with a simple structure, which can realize automatic demolding operation and self-cooling, and has multiple functions and good performance.

[0005] To solve the above-mentioned technical problems, this utility model provides a precision household appliance mold, including a moving mold fixing plate and a fixed mold fixing plate. The moving mold fixing plate is provided with a mounting base, and the mounting base is provided with a mounting shaft. A lower cavity positioning plate and an upper cavity positioning plate are sleeved around the mounting shaft. A bottom mold cavity is provided at the center of the lower cavity positioning plate, and a cover plate is provided on the upper cavity positioning plate corresponding to the position of the bottom mold cavity. An auxiliary plate is provided on the moving mold fixing plate, and an ejector plate is provided on the auxiliary plate. A push rod is provided on the ejector plate, and the push rod passes through the lower cavity positioning plate and connects to the bottom mold cavity.

[0006] Furthermore, the lower cavity positioning plate is provided with an external core-pulling structure on the periphery of the bottom mold cavity.

[0007] Furthermore, a feed inlet is provided at the center of the moving mold fixing plate, and a feed pipe is provided at the feed inlet. The feed pipe passes through the moving mold fixing plate and the upper cavity positioning plate, and an auxiliary flow channel is provided at its end. The auxiliary flow channel is connected to the cover plate.

[0008] Furthermore, the cover plate is equipped with crisscrossing cooling water pipes.

[0009] Furthermore, both the moving mold fixing plate and the auxiliary plate have through holes at their bottom centers.

[0010] Furthermore, a guide shaft is provided between the auxiliary plate and the lower cavity positioning plate, and the ejector plate can move up and down along the guide shaft.

[0011] Furthermore, a positioning ring is provided on the fixed mold fixing plate corresponding to the position of the feed tube.

[0012] The beneficial effects of this utility model are as follows: When using this device, it is placed on the workbench and fed through the top inlet. The material enters the space between the bottom mold cavity and the cover plate, which is the so-called forming cavity, through the feed pipe and the auxiliary flow channel to achieve processing. After the mold is guided, the fixed mold plate is removed, and then the upper cavity positioning plate and the cover plate are removed in sequence. The bottom ejection plate is activated, that is, the ejection plate is pushed upward by the bottom of an external object such as a cylinder. The upward movement of the ejection plate drives the ejector rod to move upward. The upward movement of the ejector rod ejects the already formed mold to achieve the overall processing operation.

[0017] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0018] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to 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 this utility model.

[0019] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0020] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; 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; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0021] In this utility model, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0022] It should be noted that when an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element.
