The application discloses a kind of convex structure 3D printing method of inner cone parts, belong to 3D printing manufacturing technical field, it includes box, the base is placed in the bottom of the box, the outer side of the base is fixedly installed with portal frame, the first motor is installed in the base side, the fan that is used with the air suction pipe is installed in the working tank, the filter plate is installed in the first fixed block buckle;Through the extension head structure design to the inner wall of inner cone part main body, extension head itself has the effect of strengthening the overall structure support strength of part, the use amount of extension head and part inner wall part support can be greatly reduced when D printing, not only reduce the support material cost, but also can reduce subsequent support piece removal process, avoid to cause damage to extension head, part inner wall when removing support, further improve part forming quality and production efficiency, especially adapt to the precise printing demand of complex convex structure such as inner cone part inner wall extension head with structural strengthening function.

This invention discloses a mold mechanism for an integral sunroof frame instead of a split sunroof frame, relating to the field of sunroof frame mold technology. It includes a rear template, a support plate, an ejector plate, and a clamping plate connected in sequence. The rear template is provided with split rear mold cores and positioning modules. The split rear mold cores include rear mold core one, rear mold core two, rear mold core three, rear mold core four, rear mold core five, and rear mold core six. The positioning module includes rear mold positioning mold one and rear mold positioning mold two. This application provides a mold mechanism for an integral sunroof frame instead of a split sunroof frame. A hydraulic cylinder drives a slider to move towards the cavity side, closing the side forming area of ​​the H-shaped product. Together with the split rear mold cores, it forms a complete H-shaped product forming cavity. The opening and closing of the side cavity is completed by the hydraulic cylinder-driven slider, with stable action response, adapting to the side forming requirements of H-shaped products. The structure of the split mold cores also reduces the contact resistance between the product and the mold cores, improving demolding smoothness.

The application discloses a preparation method of a molybdenum end cap and the molybdenum end cap prepared thereby, and relates to the field of metal products. The preparation method of the molybdenum end cap comprises the following steps: uniformly mixing molybdenum powder, a binder and a solvent according to a weight ratio, granulating and removing the solvent to obtain molybdenum particles; the binder comprises isocyanate-terminated polyurethane prepolymer, polyglycol monomethyl ether glycidyl ether, polyvinyl butyral and a diluent according to a weight ratio of (20-30):(8-12):(35-40):100; the molybdenum particles are compression molded to obtain a molybdenum end cap before debinding; and the molybdenum end cap before debinding is subjected to debinding, wherein the debinding comprises the steps of primary debinding, secondary debinding and tertiary debinding, the temperature of the primary debinding is 560-780 DEG C, the temperature of the secondary debinding is 880-950 DEG C, and the temperature of the tertiary debinding is 1200-1300 DEG C. The application can improve the stability of the molybdenum particles forming the molybdenum end cap, and simultaneously improve the problem that organic substances are easily left in the molybdenum end cap, thereby causing the purity of the molybdenum end cap to be not high.
