Embodiment Construction

[0022] Combine below figure 2 , the present invention is further described:

[0023] A mold comprising a mandrel 3, an integral upper die 1 and an integral lower die 2, the integral upper die 1 is composed of a basic upper die 11 and a quick-change upper die 12, the basic upper die 11 is fixedly connected to the main oil cylinder of a machine tool, The quick-change upper die 12 presses down on the upper surface of the workpiece 5. The quick-change upper die 12 is a detachable and replaceable structure. The basic upper die 11 and the quick-change upper die 12 are fixed by fixing bolts; The lower mold 21 and the quick replacement mold 22 are combined, the basic lower mold 21 is fixedly connected with the machine tool, the lower end surface of the workpiece 5 is positioned on the quick replacement mold 22, the quick replacement mold 22 is a detachable replacement structure, and the basic lower mold 21 and change die 22 quickly and also fix by fixing bolt.

Abstract

The invention relates to a die. The die comprises an integral upper die (1) and an integral lower die (2), wherein a supporting device (7) is arranged between the integral upper die (1) and the integral lower die (2), the integral upper die (1) is formed by combining a basic upper die (11) and a quick-change upper die (12), the basic upper die (11) is fixedly connected with a main cylinder of a machine tool, the quick-change upper die (12) presses the upper end face of a workpiece, and the quick-change upper die (12) is in a detachable replacement structure; and / or the integral lower die (2) is formed by combining a basic lower die (21) and a quick-change lower die (22), the basic lower die (21) is fixedly connected with the machine tool, the lower end face of the workpiece is positioned on the quick-change lower die, and the quick-change lower die is in a detachable replacement structure. The die has the beneficial effects that supporting blocks can be arranged above a supporting base or are separated, can well protect the lower die from being stressed when the die does not work, and can avoid loss of the supporting device when the die works; the operation is simple and convenient.

Description

technical field [0001] The application date of this invention is January 11, 2013, the application number is: 201310009127.5, and the divisional application of the invention patent application named "a mold". The invention relates to a mold. Background technique [0002] At present, in the field of press quenching of heat treatment parts, integral molds are used for the press quenching of main reducer and synchronizer parts. If the type is to be changed, all the integral molds need to be replaced. During the process of mold replacement, the parallelism between the molds and the The amount of pressing needs to be readjusted, the adjustment is very cumbersome, the cycle time is long, the labor force is also large, the efficiency of changing varieties is very low, and there is a hidden danger of unstable quality. [0003] Such as figure 1 As shown, the existing main reduction and synchronizer press quenching dies include an integral upper die 1, an integral lower die 2 and an...
