Embodiment Construction

[0016] The preferred embodiments of the present invention are given below in conjunction with the accompanying drawings to describe the technical solution of the present invention in detail.

[0017] Such as figure 1 and 2 As shown, the mold of the industrial filter seat of the present invention includes a body casting mold 6 for casting the filter seat body 1 , and a cavity is formed in the middle part of the body casting mold 6 . The body casting mold is a prior art and will not be described in detail here. The industrial filter holder mold of the present invention also includes a middle hole casting mold for casting the middle hole 11 passing through the filter holder body 1 on the filter holder body 1 .

[0018] The middle hole mold includes a pair of slider cores 2 that are separated from the opposite sides of the main body mold 6. The sum of the lengths of the two slider cores 2 is greater than or equal to the depth of the middle hole 11. The two slider cores 2 The di...

Abstract

The invention discloses a mould of an industrial filter base and a using method of mould of the industrial filter base. The mould comprises a body cast mould for casting a filter base body and a middle-hole cast mould; the middle-hole cast mould comprises at least one pair of slide block mould cores which is respectively arranged at two sides of the body cast mould and arranged oppositely to form a middle-hole in the filter base body; the middle-hole cast mould also comprises propelling units corresponding to the slide block mould cores one by one; and telescopic components of the propelling units are connected with the slide block mould cores through rigid components to drive the pair of slide block mould cores to approach to each other. When the mould of the industrial filter base is finally ejected, the slide block mould cores are propelled and extruded again by the propelling units, so that the two slide block mould cores are further extruded and preserved in molten metal in an extruding process to achieve the full-compensation purpose. According to the method disclosed by the invention, the density of the middle-hole of the filter base is greatly improved, and the phenomena of air holes and shrinkage cavities are reduced.

Description

technical field [0001] The invention relates to a mold and its use method, in particular to a mold for an industrial filter seat and its use method. Background technique [0002] figure 1 The working filter seat in is an existing product. The middle hole of the filter seat body 1 requires no air holes on the surface after processing, which is difficult to achieve for ordinary die-casting, because the middle hole is formed by the slider cores on both sides. Considering The hole depth in the middle is relatively large, which undoubtedly requires a large die slope, the subsequent finishing machining allowance is large, and air holes are unavoidable. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a mold for an industrial filter seat and its use method in order to overcome the defect that the mold of the filter seat in the prior art is likely to cause air holes in the middle hole of the filter seat. [0004] The pr...
