Embodiment Construction

[0018] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0019] see figure 1 , figure 2 , image 3 with Figure 4 , a hydraulic punch assembly, including a housing 8, a punch 9 and a punch return spring that drives the punch to move from above. A punch connection hole 10 with a closed upper end is provided on the lower end surface of the shell. The punch sliding seal is penetrated in the punch connecting hole to enclose a hydraulic chamber 11 in the punch connecting hole. An annular cutting edge 12 is provided on the lower end face of the punch. An elastic element 13 is provided on the lower end face of the punch. The elastic element is a rubber block. When the elastic element is in a free state, its lower end exceeds the annular cutting edge downwards. The elastic element can be squeezed until the lower end shrinks to be located above the annular cutting edge. The elastic element is located in the ...

Abstract

The invention relates to a hydraulic punch assembly. The hydraulic punch assembly comprises a shell, a punch and a punch reset spring which drives the punch to move from the top. A punch connecting hole with the upper end closed is formed in the lower end face of the shell; the punch is slidably arranged in the punch connecting hole in a sealing and penetrating mode, and a hydraulic cavity is formed in the punch connecting hole in an enclosed mode; and an annular cutting edge is formed in the lower end face of the punch. The hydraulic punch assembly is used for punching medicine bags after themedicine bags are subjected to injection molding, and the medicine bags with and without holes can be produced in a co-mold mode conveniently.

Description

technical field [0001] The invention relates to the technical field of automatic production of traditional Chinese medicines, in particular to a hydraulic punch assembly. Background technique [0002] In the process of traditional Chinese medicine production, the traditional Chinese medicine solution is stored in a medicine bag. Medicine bags are sometimes designed with a hole for hanging. The existing medicine bag holes are synchronously formed by the mold during injection molding. At this time, different molds are needed to produce medicine bags with and without holes, so that the versatility of the mold is poor. Contents of the invention [0003] The invention provides a hydraulic punch assembly, which is used for punching a medicine bag after injection molding, so that the medicine bag with holes and without holes can be co-molded and produced. [0004] The above technical problems are solved by the following technical solutions: a hydraulic punch assembly, including...
