Embodiment Construction

[0016] Referring to the accompanying drawings, the present invention is a sand core coupler, which is used for the connection between sand cores and sand cores or between sand cores and sand molds in sand casting production. The mark A in the figure is a sand core, and B is a sand core or a sand mold.

[0017] This sand core coupler is made up of spare parts such as coupler 2, coupler sleeve 3, hook 4, preventer 1, stage clip 6. The two break-off devices 1 are respectively arranged at the ends of the coupling piece 2 and the coupling sleeve 3. The break-off devices 1 are round or cross-shaped to strengthen the connection with the core (type) sand and prevent the coupler from falling from the core (type) out of the sand.

[0018] The coupling piece 2 is set into the coupling sleeve 3 and connected with the coupling sleeve 3 and the hook 4 . The front part of the coupling part 2 is provided with a guide part 21 and a coupling part 22 , the coupling part 22 serves as the head o...

Abstract

The invention relates to a sand core connector which comprises a connecting piece, a connecting sleeve and a hanger which are connected with the connecting piece, and loosing prevention devices which are respectively arranged on the end parts of the connecting piece and the connecting sleeve; the front part of the connecting piece is provided with a guide part and a connecting part which serves as a head; the guide part and the connecting part are together inserted into the connecting sleeve; the connecting part is provided with a neck which is hooked by the hanger that is fixedly arranged in the connecting sleeve by a hanger axle. The sand core connector of the invention is used for connecting the sand cores and connecting the sand core with the sand mold in the foundry production of sand mold, has the position function and can prevent the shifting or drifting of the sand core. The adoption of the sand core connector can greatly simplify the connection form between sand cores, and between the sand core and the sand mold, increase the connection strength so that the casting technological design, the mould manufacturing and the actual operation become more convenient and simplified, thus having excellent utility value for the sand mold casting production.

Description

technical field [0001] The invention relates to sand casting, in particular to a sand core coupler for effectively connecting sand cores or between sand cores and sand molds. Background technique [0002] In sand casting production, there are often combined moldings of sand cores and sand cores, sand cores and sand molds, especially when cores are assembled and isolated small sand cores are installed on the mold, the effective connection between them often creates troubles, and it is often difficult to cast. The occurrence of sand core displacement or drift will affect the quality of the casting, and in severe cases, the casting will be scrapped. [0003] How to conveniently and reliably connect sand cores and sand cores, and between sand cores and sand molds, if this problem is solved, will have good practical value in actual production. Contents of the invention [0004] The task of the present invention is to provide a sand core coupler, which solves the problem that t...
