Embodiment Construction

[0032] The specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific embodiments.

[0033] Unless expressly stated otherwise, throughout the specification and claims, the term "comprise" or variations thereof such as "includes" or "includes" and the like will be understood to include the stated elements or constituents, and not Other elements or other components are not excluded.

[0034] Such as figure 2 As shown, according to the preferred embodiment of the present invention, the core frame support 1 with a stepped shape is installed on the lower core box. The core frame support 1 has a four-layer step structure, and the four-layer step structure includes: the first layer of steps 11, the second layer Steps 12, third steps 13 and fourth steps 14. Wherein, the first step 11 is arranged on the top ...

Abstract

The invention discloses a core bar support with a step shape and an application method thereof. The core bar support is arranged on a lower core box. The core bar support is of a four-step structure and comprises a first step, a second step, a third step and a fourth step, wherein the first step is arranged at the top of the core bar support and is used for penetrating on a core bar, and the corebar is supported through the bottom of the first step; the second step is arranged under the first step and has a draft angle so as to demould; the third step is arranged under the second step and isused for positioning the core bar support; and the fourth step is arranged under the third step and is used for being fixed on the lower core box. An abdicating hole corresponding to the first step isformed in the core bar and does not penetrates through the core bar. The length of the first step is set, when the first step penetrates into the abdicating hole, the bottom of the first step can bepressed on the core bar so as to prevent the core bar from overturning or shifting under the impact of a sand flow. The core bar support has the advantages of small size and stable supporting.

Description

technical field [0001] The invention relates to the field of casting technology, in particular to a step-shaped core brace and a method for using the same. Background technique [0002] The core bone in sand casting is used to firmly connect the entire sand core to form a whole, so as to ensure that the sand core will not break during the production and transportation process. Its main function is to increase the rigidity of the sand core and strength. In addition, the mandrel is also used for lifting, so as to facilitate the transfer and transportation of the sand core. [0003] The sand core bone support is designed and installed on the mold, generally installed on the lower core box, to support and fix the core bone, so as to prevent the sand core from being scrapped due to the moving position of the core bone during the core making process. [0004] At present, in order to facilitate the placement of the core bone and prevent the core bone from moving on the core bone ...
