Abstract
The utility model belongs to the technical field of lost foam molds, and particularly relates to an automatic loose core lost foam mold for a main speed reducer shell cylinder. The automatic loose core lost foam mould for the main speed reducer shell cylinder comprises an upper mould, a middle steam frame and a lower mould; the middle steam frame is positioned between the upper die and the lower die; the method is characterized in that: a plurality of inserts for forming the side core pulling inverted buckle part are fixed on the middle steam frame; the lower part of the insert is provided with a loose core movable block, and a loose core cylinder for driving a loose core sliding block to act is arranged at the outer side of the middle steam frame corresponding to the loose core movable block. According to the automatic core-pulling lost foam mold for the main speed reducer shell cylinder, the side core-pulling back-fastening part is made into the plurality of inserts, the plurality of inserts are fixed on the steam frame, and the core-pulling movable block moves below the inserts, so that automatic mold stripping of the mold is realized.
Description
Technical Field
The utility model belongs to the technical field of lost foam molds, and particularly relates to an automatic loose core lost foam mold for a main speed reducer shell cylinder.
Background
The main reducer shell has large product volume and complex outer side structure, and the common side core-pulling structure has a back-off, so that the common core-pulling structure can not realize automatic mold stripping due to the back-off.
Disclosure of Invention
In order to solve the technical problems, the utility model aims to provide an automatic core-pulling lost foam mould for a main speed reducer shell cylinder.
The utility model adopts the following technical scheme for accomplishing the purposes:
the automatic loose core lost foam mould for the main speed reducer shell cylinder comprises an upper mould, a middle steam frame and a lower mould; the middle steam frame is positioned between the upper die and the lower die; a plurality of inserts for forming the side core pulling inverted buckle part are fixed on the middle steam frame; the lower part of the insert is provided with a loose core movable block, and a loose core cylinder for driving a loose core sliding block to act is arranged at the outer side of the middle steam frame corresponding to the loose core movable block.
The insert is L-shaped, and two core-pulling sliding blocks are correspondingly arranged below each insert.
According to the automatic core-pulling lost foam mold for the main speed reducer shell cylinder, the side core-pulling back-fastening part is made into the plurality of inserts, the plurality of inserts are fixed on the steam frame, and the core-pulling movable block moves below the inserts, so that automatic mold stripping of the mold is realized.
