Problems solved by technology

[0002] The existing tail frame forming mold uses the upper mold and the lower mold to fasten each other to form the tail frame process cavity, and then injects the slurry to form it. After the tail frame is formed, it needs to be demoulded. The existing demoulding method mainly uses manual Prying one or both ends of the mold is not only time-consuming and labor-intensive, but also takes a long time, and the tail frame stays in the mold for a long time, which will cause deformation of the mold surface and shorten the service life of the mold. The pried part is very easy to be damaged, resulting in a very high scrap rate

Abstract

The invention discloses a mold for forming a tail frame, which comprises a lower mold on a bracket and an upper mold directly above the lower mold and connected to a hydraulic lifting pump, a fixing frame is also arranged between the lower mold and the bracket, and the fixing The frame is provided with at least three threaded through holes connecting the lower mold and the bracket, and the threaded through holes are evenly arranged on the fixed frame horizontally, and the threaded through holes are provided with threaded rods that match the threaded through holes. The top surface of the threaded rod coincides completely with the opening surface of the threaded through hole. The invention has its own demoulding device, which avoids the problems of time-consuming and laborious demoulding, high strength, and easy damage to the mold and molding tail frame caused by manual prying. It not only greatly improves the demoulding efficiency, Moreover, the molding quality of the tail frame after demoulding is guaranteed, the scrap rate is greatly reduced, and the production profit is improved.

Description

technical field [0001] The invention specifically relates to a mold for forming a tail frame. Background technique [0002] The existing tail frame forming mold uses the upper mold and the lower mold to fasten each other to form the tail frame process cavity, and then injects the slurry to form it. After the tail frame is formed, it needs to be demoulded. The existing demoulding method mainly uses manual Prying one or both ends of the mold is not only time-consuming and labor-intensive, but also takes a long time, and the tail frame stays in the mold for a long time, which will cause deformation of the mold surface and shorten the service life of the mold. The pried part is very prone to damage, resulting in a very high scrap rate. Contents of the invention [0003] Purpose of the invention: In order to overcome the deficiencies in the prior art, provide a tail frame forming mold that is simple, fast and effective to remove from the mold and can avoid damage to the tail f...
