Description
Technical Field
[0001] This utility model belongs to the field of optical mirror barrel production technology, specifically relating to an optical mirror barrel production mold. Background Technology
[0002] An observation camera is a type of imaging device specifically designed for recording, measuring, and analyzing target objects. It is widely used in the aerospace field. An observation camera typically consists of an outer shell (and an optical mirror tube) and various components installed inside it. Among these, the optical mirror tube is the main load-bearing component of the observation camera, and its performance directly affects the camera's functionality. The traditional manufacturing method for the optical mirror tube mainly involves forming aluminum alloy sheets and then welding them, resulting in a relatively high weight. With the popularization of composite materials, composite materials have begun to be widely used in optical mirror tubes. After covering a frame with a skin, it is placed in a mold cavity and hot-pressed. Existing hot-press molds typically include an inner mold frame and an outer mold frame. When covering the skin, one layer of skin is first laid on the inner mold frame, then the frame is fitted in, another layer of skin is laid on top, and finally the outer mold frame is fitted in. This design makes it easy to scratch the unformed outer skin when fitting the outer mold frame, resulting in surface defects on the optical mirror tube after hot pressing, including wrinkles and damage.
[0003] Therefore, how to avoid defects on the surface of the optical mirror tube after hot pressing is a technical problem that urgently needs to be solved in this field.
[0004] It should be noted that the information disclosed in this background section is only for understanding the background technology of the present application concept, and therefore, the above description is not considered to constitute prior art information. Utility Model Content

Similarly, the tensioning strip 41 at the bottom is connected to the waist-shaped hole 12 on the base 1, and the auxiliary bolts 13 are inserted into the waist-shaped holes 12. The auxiliary bolts 13 can be locked after the first template 31 is tensioned and positioned, so as to ensure that the first template 31 is perpendicular to the top cover 5 and the base 1.
[0037] In some embodiments, the second template 32 is fitted to the side wall of the first template 31, and the side wall of the second template 32 is bolted to a positioning block 32a. The side wall of the positioning block 32a has a positioning notch 32b, which is engaged with the side wall of the first template 31 to limit the second template 32.

[0041] In the description of the embodiments of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" 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 this utility model based on the specific circumstances.
[0042] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this utility model 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 this utility model. Furthermore, terms such as "first," "second," and other numerical terms used herein do not imply order or sequence unless expressly indicated herein. Therefore, without departing from the teachings of the exemplary embodiments, the first element, component, region, layer, or segment discussed above may be referred to as the second element, component, region, layer, or segment.
[0043] Spatially relative terms, such as “inside,” “outside,” “below,” “below,” “down,” “above,” “up,” etc., may be used herein to describe the relationship between one element or feature illustrated in the figures and another element or feature. In addition to the orientations depicted in the figures, spatially relative terms may be intended to cover different orientations of the device in use or operation. For example, if the device in the figure is flipped, an element described as “below” or “below” other elements or features would be oriented as “above” other elements or features. Thus, the example term “below” can cover both above and below orientations. The device may be oriented in other ways (rotated 90 degrees or in other orientations), and the spatially relative descriptors used herein are interpreted accordingly.
[0044] In the above discussion, unless otherwise stated, when used to describe numerical values, the terms “about,” “approximately,” “basically,” etc., indicate a change of + / - 10% in that value.
[0045] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
