A stripping device for sand core making that facilitates control of the amount of blanking

Abstract

The invention provides a discharging device applied to manufacturing of a sand core and realizing convenient control on discharging amount and relates to the technical field of a device used for manufacturing a sand core applied to casting. The discharging device comprises a pedestal, a bracket, a sand core manufacturing component, a quantitative discharging component and a molding press, whereinthe bracket is fixedly arranged on the pedestal; the sand core manufacturing component is fixedly arranged at the left end of the upper side of the bracket; the quantitative discharging component is fixedly arranged at the right end of the bracket and is arranged at the lateral lower direction of the sand core manufacturing component; the quantitative discharging component and the sand core manufacturing component are arranged in a penetration manner; the molding press is fixedly arranged on the pedestal and is arranged at the right side of the bracket; and a feeding opening of the molding press and a discharging opening of the quantitative discharging component are arranged in a communicating manner. The discharging device realizes control on the discharging amount in a discontinuous discharging and compaction way, can realize discharging of a wet sand core after preliminary compaction, can realize precise control on the discharging amount of the wet sand core, and guarantees the finished product rate of manufacturing of the sand core.

Description

technical field [0001] The invention relates to the technical field of sand core preparation devices for casting, in particular to a material stripping device for sand core production which can conveniently control the amount of material to be cut. Background technique [0002] Stripping casting needs to use sand cores to shape the product; sand cores are products that are formed by mixing dry core sand and plastic plastic and then pressed through molds. When preparing sand cores, in order to ensure the production rate of sand cores, the Control the feeding amount of wet core sand. [0003] In the prior art, when preparing sand cores, the feeding amount of wet core sand is controlled by manual observation. This method of controlling the amount of feeding depends too much on the operator's work experience, and the wet core sand being fed is in a loose state. Misjudgment is prone to occur; although the excessive amount of wet core sand can be added to ensure sufficient cuttin...

[0003] In the prior art, when preparing sand cores, the feeding amount of wet core sand is controlled by manual observation. This method of controlling the amount of feeding depends too much on the operator's work experience, and the wet core sand being fed is in a loose state. It is prone to misjudgment; although the excessive amount of wet core sand can be added to ensure a sufficient amount of material when pressing the sand core, the discarded wet core sand after the excess will cause a large waste of resources and needs to be improved
