Sand core tray with self-guiding function

Abstract

The invention discloses a sand core tray with an automatic guiding function. The sand core tray comprises a bottom plate and a positioning pin on the bottom plate, wherein the positioning pin is divided into a matching section and a guiding section in sequence from the bottom to top; the matching section is matched with a sand core positioning point; the diameter of the guiding section is smaller than that of the matching section; the joint of the guiding section and the matching point is in smooth transition; a lifting through hole and a limiting through hole are formed in the bottom plate; a support pillar glidingly penetrates through the lifting through hole; the lower end of the support pillar is connected with a driving device; a thrust ball bearing is arranged at the upper end of the support pillar; the upper surface of the thrust ball bearing is supported and connected with a guiding plate which is adjacent to the positioning pin; a limiting rod corresponding to the limiting through hole in the aspect of position is arranged on the lower surface of the guiding plate; the limiting rod glidingly penetrates through the limiting through hole; a gap exists between the limiting rod and the limiting through hole. According to the sand core tray with the automatic guiding function, the automatic guiding function of sand cores can be realized, so that the positioning in manual sand core putting can be rapidly and effectively improved and the positioning of different sand cores can be satisfied.

Description

Technical field [0001] The invention relates to a sand core tray, in particular to a sand core tray with an automatic guiding function. Background technique [0002] After the core-making process is completed, the sand core often needs post-processing, such as core removal, core assembly, dipping, core removal and other processes. Normally, the sand core placed in the sand core tray is clamped by a robotic arm for the next step. Since the actions of the robotic arm are carried out in accordance with the set procedure, the sand core needs to be accurately placed in the preset position to ensure that the robotic arm can accurately grip the sand core. [0003] The positioning of sand cores is generally achieved by setting positioning points on the sand cores and positioning pins on the bottom plate of the sand core tray, so as to achieve the fit between the positioning points of the sand core and the position of the positioning pins. The original sand core tray is manually placed in t...

Problems solved by technology

[0003] The positioning of the sand core is generally done by setting the positioning point on the sand core and setting the positioning pin on the bottom plate of the sand core tray, so as to realize the matching between the positioning point of the sand core and the position of the positioning pin. When the sand core positioning point is docked with the positioning pin, since the sand core tray is a dead limit, the positioning can only be performed by moving the position of the sand core, and it is often impossible to quickly, effectively and flexibly realize the alignment of the positioning pin and the positioning point of the sand core docking
