Problems solved by technology

[0005] The purpose of the present invention is to provide a mold for the production of filter housings, which has the advantages of soft contact between the upper mold and the lower mold and reduces possible damage caused by collisions, and solves the problem of rigid contact between the upper mold and the lower mold. The noise generated by the collision is large, and it is easy to damage the mold due to the collision

Abstract

The invention discloses a filter shell production die which comprises a lower die and an upper die. A first frame is fixed to the bottom of the lower die, two casing pipes are symmetrically fixed to the four edges of the outer side of the upper surface of the first frame correspondingly, inner columns are movably installed in the casing pipes, and first connecting blocks are fixed to the top ends of the inner columns. Springs are fixed between the lower surfaces of the first connecting blocks and the upper surface of the first frame, the casing pipes and the inner columns are sleeved with the springs, a second frame is fixed to the top of the upper die, two stand columns are symmetrically fixed to the four edges of the outer side of the lower surface of the second frame correspondingly, second connecting blocks are fixed to the bottom ends of the stand columns, and the upper die is placed on the lower die. The filter shell production die has the advantages that the upper die and the lower die are in soft contact, and damage possibly caused by collisions is reduced.

Description

technical field [0001] The invention relates to the technical field of filter housing production, in particular to a mold for filter housing production. Background technique [0002] A filter is a filter circuit composed of capacitors, inductors and resistors. The filter can effectively filter the frequency point of a specific frequency in the power line or frequencies other than this frequency point to obtain a power signal of a specific frequency or eliminate a power signal of a specific frequency. [0003] The filter is a frequency selection device, which can pass specific frequency components in the signal and greatly attenuate other frequency components. Using this frequency selection function of the filter, it can filter out interference noise or perform spectrum analysis. [0004] The filter housing is produced by moulding, and the electrical components of the filter are installed in the housing. Generally, the molds for shell production are divided into upper and l...
