Embodiment Construction

[0015] like figure 1 An upper mold for a hydraulic press shown in -3 includes an upper mold 2 and an upper mold base 1. The middle part of the upper mold 2 has a protrusion, and the protrusion is a cone or cylinder with a hemispherical top. The upper mold 2 and the upper mold The base 1 is fixed by bolts.

[0016] The upper die 2 also includes a middle pressure head and a "T"-shaped connector 3. The middle pressure head is a raised part of the upper die 2. There is a through hole in the middle of the middle pressure head. The size of the through hole is vertical to the "T"-shaped connector 3. Partially matched, the middle pressure head and the "T" type connector 3 are connected by bolts.

[0017] The upper mold base 2 is a steel plate, and the two edges protrude upwards, and the protruding part is fixed with the horizontal part of the "T" type connector 3 with bolts.

[0018] Multiple "T"-shaped connecting pieces 3 are fixed on one piece of hydraulic press, and each "T"-shap...

Abstract

The invention provides an upper die for an oil press. The upper die for the oil press comprises an upper die body and an upper die base, a protrusion is arranged in the middle of the upper die body, the protrusion is a cone or a cylinder with a hemispheroid top, and the upper die body and the upper die base are fixed through a bolt. A T-shaped connection part is inserted into a through hole of a medium pressing head and fixed through the bolt, the vertical portions of different T-shaped connection parts are matched with through holes in corresponding medium pressing heads in size, each T-shaped connection part is matched with the specific medium pressing head, and therefore the aims that the efficiency for replacing the upper die is improved and the cost is reduced are achieved.

Description

technical field [0001] The present invention relates to a hydraulic press, in particular to an upper mold for a hydraulic press. Background technique [0002] When changing the upper mold of the hydraulic press, the entire upper mold needs to be replaced together, and the upper mold is heavy, so it is cumbersome to replace, the efficiency is low, and the cost is wasted. Contents of the invention [0003] In order to improve the efficiency of replacing the upper die and reduce the cost, the upper die is divided into a "T"-shaped connector and a middle pressure head, and the upper die can be replaced by replacing a different middle pressure head. [0004] The purpose of the present invention is specifically achieved through the following technical solutions: [0005] An upper mold for a hydraulic press, comprising an upper mold and an upper mold base, the middle part of the upper mold has a protrusion, and the protrusion is a cone or cylinder with a hemispherical top, and t...
