Embodiment Construction

[0027] A method for manufacturing a core box mold with complex spatial surfaces, characterized in that: the method includes the following steps:

[0028] a. Material selection: Use wood to make the bracket mold body, and add a 20mm thick conformal steel frame outside the body for load-bearing reinforcement;

[0029] b. Establish the three-dimensional space model of the mold: use UG software, use the point-by-point grid surface method to model the three-dimensional space of the model, and then design a conformal steel frame around the model to ensure that the steel frame is completely consistent with the mold body of the bracket;

[0030] c. Make the main load-bearing steel frame: according to the size and shape of the model designed in the previous order, accurately weld the conformal steel frame;

[0031] d. Make the mold blank: use the welded main load-bearing steel frame to carry out segmental ring material, and each segment is divided into regional ring material, and when ...

Description

technical field [0001] The invention relates to a method for manufacturing a mold, in particular to a method for manufacturing a core box mold with a complex space and curved surface, which is suitable for ship supports of ocean-going scientific research ships and deep-water drilling ships. Background technique [0002] The complex curved surface of the ship support space is completely a three-dimensional space model, and its ring material production is extremely difficult, and the strength cannot be guaranteed at all; and due to the structural design of the ship support itself, the mold is very easy to deform, and the dimensional accuracy is also difficult to guarantee. If the conventional production method is followed, the mold will not only consume a lot of materials, but also be very heavy, which will increase the difficulty of sand filling molding, and the quality of sand mold manufacturing will be very low. It is very large, and the scrap rate is also high, reaching a ...
