Description

Technical Field

[0001] This utility model relates to the field of mold technology, specifically to an aerospace mold design structure for products with negative angles on the forming surface. Background Technology

[0002] Currently, the demolding technology for complex aerospace molds generally involves the coordinated action of components such as the lower mold plate, upper mold plate, hydraulic cylinder, push plate, and ejector pins to complete the demolding process. In the design of complex aerospace molds, the forming surface of the product is mostly irregular in shape, and sometimes the forming surface of the product has a negative angle. This causes the product to be unable to be removed smoothly during the demolding process, or even stick to the mold. This technology usually requires complex techniques and precise coordination. If the coordination is not good, the plastic part may stick to the mold, especially when the forming surface of the product has a negative angle feature, which will lead to demolding difficulties. In the production and manufacturing process, these problems not only affect production efficiency and increase costs, but may also have an adverse impact on product quality. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides an aerospace mold design structure for products with negative angles on the molding surface, solving the problem of existing plastic parts adhering to the mold and causing difficulties in demolding.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution: an aerospace mold design structure for a product forming surface with a negative angle, including a first connecting plate and a second flange, wherein the first connecting plate is provided with an insert, a connecting mechanism is provided between the insert and the first connecting plate, and a pair of first bolt holes are provided on the side wall of the insert.

[0005] The second flange is provided with a split module, and the side wall of the split module is provided with a pair of second bolt holes.

[0006] Preferably, the connecting mechanism includes grooves formed on the lower walls of both sides of the insert, a pair of positioning mounting blocks are installed in each of the grooves, the pair of positioning mounting blocks are bolted to the first connecting plate, and the insert has an arc-shaped surface.

[0007] Preferably, a pair of fixing blocks are provided on the lower walls of both sides of the split module, and the two pairs of fixing blocks are connected to the second flange. The split module is an arc-shaped block, and the arc of the arc-shaped block is the same as the arc of the arc surface.

[0008] Preferably, the first connecting plate and the second flange are respectively provided with a plurality of connecting holes. Beneficial effects

[0009] This utility model provides a design structure for an aerospace mold with a negative angle on the product molding surface, which has the following beneficial effects and incorporates a split-type and insert-type structural design:

[0010] The mold forming surface is divided into left and right parts. One part is designed as an insert structure, and the other part is designed as a split module. Positioning blocks are used for positioning and installation. During demolding, due to the negative angle features of the internal surface of the product, the product will interfere with the internal surface of the mold. At this time, the positioning and installation blocks on the insert need to be separated from the flange in turn, and then the bolts on the split module need to be removed. Through the reserved groove position, the insert can be moved slightly and no longer interfere with the molded product. In this way, the subsequent demolding work can continue.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figs. 1-2 This utility model provides a technical solution: an aviation mold design structure for a product forming surface with a negative angle, including a first connecting plate 1 and a second flange 2, the first connecting plate 1 is provided with an insert 3, the insert 3 and the first connecting plate 1 are provided with a connecting mechanism, and the side wall of the insert 3 is provided with a pair of first bolt holes 5.

[0016] The second flange 2 is provided with a split module 4, and the side wall of the split module 4 is provided with a pair of second bolt holes 6;

[0017] The mold forming surface is divided into left and right parts. One part is designed as an insert structure and the other part is designed as a split module. Positioning and installation blocks 8 are used for positioning and installation. Strictly ensure that there are no gaps on the installation edge of the insert 3. While ensuring that the overall mold surface and the reference surface have stable geometric shape and dimensional relationship, the modules are combined and connected.

[0018] The insert 3 is fitted onto the split module 4. Since the insert 3 and the split module 4 are provided with corresponding first bolt holes 5 and second bolt holes 6, they are fixed by bolt connection.

[0019] Furthermore, the connecting mechanism includes grooves 7 formed on the lower walls of both sides of the insert 3, and a pair of positioning mounting blocks 8 are installed in each of the grooves 7. The pair of positioning mounting blocks 8 are bolted to the first connecting plate 1, and the insert 3 has an arc-shaped surface.

[0020] Furthermore, a pair of fixing blocks are respectively provided on the lower walls of both sides of the split module 4, and the two pairs of fixing blocks are connected to the second flange 2. The split module 4 is an arc-shaped block, and the arc of the arc-shaped block is the same as the arc of the arc surface.

[0021] Furthermore, the first connecting plate 1 and the second flange 2 are respectively provided with a number of connection holes.

The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.

[0023] Example: In use, the split module 4 is used as the installation reference. The split module 4 is installed in sequence according to the reference line on the second flange 2, and the fixing block on the split module 4 is used for positioning and installation. After fixing, each insert 3 is installed and fixed to the first flange 1 in the same way through the positioning and mounting block 8 on the outside of the insert 3, and the insert 3 is fixed to the split module 4 by bolt connection.

[0024] During demolding, the positioning mounting block 8 on the insert 3 is detached from the first flange 1 in sequence, and then the bolts on the split module 4 are detached. Through the reserved groove 7, the insert 3 can move slightly and no longer interfere with the molded product, so that the subsequent demolding work can continue.
