Embodiment Construction

[0009] Such as figure 1 As shown, the present invention provides an improved extrusion die frame, including a lower template 1 and an upper template 7, and the lower template 1 is sequentially provided with an ejector rod 9, a pad 2, a lower punch 3 and a die 4 from bottom to top, The lower punch 3 is provided with an annular ejector 5, the pad 2 and the annular ejector 5 are provided with a lower mold base 6, and the ejector rod 9 passes through the lower template 1 and the pad 2, and is connected with the annular ejector. The bottom of 5 is in contact; the upper template 7 is provided with an upper punch 8, and the circumference of the lower punch 3 is smaller than that of the upper punch 8.

[0010] In this embodiment, the circumferential dimension of the lower punch 3 is smaller than that of the upper punch 8, so that workpieces with blind holes can be easily extruded to meet production requirements.

[0011] When in use, the power unit exerts a positive force on the uppe...

Abstract

The invention belongs to the technical field of extrusion devices, and particularly relates to an improved extrusion die rack. The improved extrusion die rack includes an upper template and a lower template, the lower template, from bottom to top in sequence, is provided with an ejector rod, a pad, a lower punch and a concave die, the lower punch is externally sleeved with an annular ejector, the pad and the annular ejector are externally sleeved with a lower die base, the ejector rod passes through the lower template and the pad, and is contacted with the bottom of the annular ejector, and the upper template is provided with an upper punch. The aim of the improved extrusion die rack is to solve the problems that most of extrusion die racks in the prior art are relatively complex in structural design and are very troublesome to use.

Description

technical field [0001] The invention belongs to the technical field of extrusion devices, and in particular relates to an improved extrusion mold base. Background technique [0002] In order to meet the needs of various extrusion workpieces in the market and reduce the production cost of extrusion workpieces, factories mostly use extrusion mold bases, and the corresponding molds can be placed in the extrusion mold bases. However, most of the existing extrusion mold bases have complex structural designs and are very cumbersome to use, which greatly reduces the production efficiency of the enterprise and increases the production cost of the enterprise, which is very unfavorable for the long-term development and progress of the enterprise. Contents of the invention [0003] The technical problem to be solved by the present invention: Most of the existing extrusion mold bases have relatively complicated structural designs and are very cumbersome to use. [0004] The technical...
