Drawings

Fig. 1 is a sectional view of a novel mold material returning device of the utility model.

In the drawing, a machine tool workbench 1, a lower backing plate 2, a spring 3, an upper backing plate 4, a lower die plate 5, a lower die insert 6, a material returning core 7, an ejector rod 8, a guide hole 9, a bolt 10 and a forming cavity 11.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1, the present invention provides a technical solution: the utility model provides a novel mould material returned device, includes machine tool table 1, machine tool table 1's inside is equipped with lower bolster 2, the top of lower bolster 2 is equipped with spring 3, the top of spring 3 is equipped with upper padding plate 4, the top of upper padding plate 4 is equipped with mould lower bolster 5, the top of mould lower bolster 5 is equipped with the mould lower mould and inserts 6, the inside that the mould lower mould was inserted 6 is equipped with material returned core 7, the below of material returned core 7 is equipped with ejector pin 8, ejector pin 8 imbeds the inside of mould lower bolster 5, the both ends of ejector pin 8 respectively with upper padding plate 4 with material returned core 7 is through integrated into one piece.

Referring to fig. 1, a guide hole 9 is formed in the lower mold plate 5 of the mold, and the ejector rod 8 is inserted into the guide hole 9.

Referring to fig. 1, a bolt 10 is disposed inside the lower backing plate 2, and the bolt 10 is inserted inside the lower backing plate 2, the upper backing plate 4 and the lower die plate 5.

Referring to fig. 1, a forming cavity 11 is formed inside the lower die insert 6 of the die, and the stripper core 7 is disposed inside the forming cavity 11.

According to the novel die material returning device, the material returning device is used for installing the lower backing plate 2, the upper backing plate 4 and the spring 3 on a die through the bolt 10, the material returning core 7 compresses the material returning device spring through the die ejector rod 8 in the die pressing process, and the material returning core is ejected out through the die ejector rod by the die return material returning device spring to complete material returning.
