Universal sand shooting plate

Abstract

The invention relates to a universal sand shooting plate. The universal sand shooting plate is characterized in that the universal sand shooting plate sequentially comprises a limiting baffle (1), a support (2) and a sand shooting plate main board (3) from top to bottom; a gap exists between the limiting baffle (1) and the support (2); a gap exists between the support (2) and the sand shooting plate main board (3); a circle of connection bolt holes (7) are formed in the edge of the sand shooting plate main board (3) which is provided with a plurality of sand shooting holes (8) arranged in an array manner; the support (2) is provided with screw holes with the positions corresponding to those of the sand shooting holes in the sand shooting plate main board (3); closing screwed plugs (9) are rotationally arranged in the sand shooting holes (8); and adjusting screwed plugs (10) are formed in the screw holes of the support (2). The universal sand shooting plate has the beneficial effects the sand shooting pressure can be adjusted, the core manufacturing quality and the production efficiency are improved, the mold opening time is saved, and cost is saved.

Description

technical field [0001] The invention relates to a general-purpose sand-shooting board, and mainly relates to a general-purpose sand-shooting board for casting hot core box core-making equipment. Background technique [0002] In the traditional shell core making equipment, its sand barrel and sand shooting plate are separated structures. The sand shooting plate is a part of the mold and is fixed on the sand barrel by 20 M8 inner hexagon screws. When changing the mold core, it needs to be replaced with the same There are several problems in the whole production process of the special sand-shooting board matched with the corresponding mold: 1. The sand-shooting pressure cannot be adjusted during core making, which affects the core-making quality; 2. Each mold needs to be equipped with a special sand-shooting board. Waste of mold making time and cost; 3. To replace the sand shooting board, you need to empty the coated sand in the sand bucket, disassemble the old sand shooting bo...

[0002] In the traditional shell core making equipment, its sand barrel and sand shooting plate are separated structures. The sand shooting plate is a part of the mold and is fixed on the sand barrel by 20 M8 inner hexagon screws. When changing the mold core, it needs to be replaced with the same There are several problems in the whole production process of the special sand-shooting board matched with the corresponding mold: 1. The sand-shooting pressure cannot be adjusted during core making, which affects the core-making quality; 2. Each mold needs to be equipped with a special sand-shooting board. Waste of mold making time and cost; 3. To replace the sand shooting board, you need to empty the coated sand in the sand bucket, disassemble the old sand shooting board, and replace the new sand shooting board. The whole process is time-consuming and laborious, and the coated sand will inevitably leak out during the replacement process , resulting in waste of sand and environmental pollution; 4. A wide variety of special sand shooting boards bring inconvenience to mold management
