Description

Water rising forming mold for metal water cup

technical field

The utility model relates to a forming die for a metal water cup, in particular to a water-swelling forming die for a metal water cup.

Background technique

In the manufacturing process of metal water cups (such as stainless steel water cups and titanium metal water cups), the cup body needs to be formed. The existing forming process is completed by using a water-swelling forming mold. The water swelling forming mold mainly includes an upper mold and a lower mold. After the upper mold and the lower mold are closed, the workpiece is sealed by extruding polyurethane rubber (commonly known as beef tendon), that is, the beef tendon is sealed. This type of water swelling molding mold is prone to produce beef tendon debris during the production process. If the beef tendon debris adheres to the surface of the mold cavity, there will be pits on the mouth of the cup during water swelling molding, which will affect the shape quality of the water cup; The ribs are easily damaged and the sealing is unstable, resulting in unstable quality of the finished product; in addition, in order to have sufficient tension force, the sealing part of the tendon needs to be longer, resulting in waste of cup mouth materials. In order to solve the above technical problems, the applicant applied for a "Cup Body Water Expansion Die Structure" (ZL201420855397.8) on December 30, 2014. The length of the stainless steel material at the mouth saves material costs and reduces the pit rate.

However, there are still some technical defects in the use of the "Cup Body Water Expansion Die Structure" (ZL 201420855397.8): the recovery of the lower mandrel 8 requires the elastic force of the knocking tendon II 13 and the release of the lower mandrel chuck 15 Need the elastic force of beef tendon IV 16, the falling back of upper mandrel 6 needs the elastic force of beating beef tendon I 20, the release of upper mandrel chuck 17 needs the elastic force of beef tendon III 18, this structure utilizing the beef tendon elasticity, a The elastic force is limited; the second is that it is damaged quickly and is not durable; the third is that the connection structure between the upper end of the upper mandrel, the lower end of the lower mandrel and the corresponding parts is relatively complicated, the manufacturing cost is relatively high, and the assembly requirements are high. inconvenient.
