[0002] Lighting fixtures are essential in everyday life, providing illumination in dark environments. However, lighting fixtures typically undergo injection molding before being released to the market. Current round lampshades are formed from plastic materials through a mold, then removed from the mold after cooling. However, due to the lack of a robust cooling system, current molds experience slow cooling and fail to achieve timely cooling, impacting both the efficiency and quality of the final molding process.

[0009] Furthermore, the upper pressing mold is a mold of solid cylindrical structure, the radius of which is smaller than the radius of the inner surface of the lower pressing mold; the lower pressing mold is a hollow cylindrical mold with an open top.

[0010] Compared with the prior art, the utility model has the following advantages:

[0011] (1) The present invention rapidly cools the die-cast lighting fixture by continuously introducing cooling water into the lower die, thereby enabling faster shaping and improving the production quality of the lighting fixture, while also accelerating the cooling rate and achieving a better cooling effect.

[0012] (2) The utility model also provides a cooling fan on the base, and the air outlet of the cooling fan blows directly toward the downward pressing mold, thereby accelerating the cooling and shaping of the lighting fixture and further improving the cooling efficiency.

[0016] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0017] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but rather merely represents selected embodiments of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort are also within the scope of protection of the present invention.

[0018] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0019] In the description of the present invention, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, or are the orientation or position relationship in which the utility model product is usually placed when in use. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as a limitation on the present invention.

[0020] It should be noted that the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of the technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, "plurality" means two or more, unless otherwise specifically defined.

[0021] Furthermore, terms such as "horizontal" and "vertical" do not necessarily mean that a component must be absolutely horizontal or overhanging, but rather that it can be slightly tilted.
