Three-in-one sealed flexible core setting fixture

Abstract

The invention discloses a three-in-one sealed flexible core setting fixture, which is formed by combining three sets of fixtures, e.g., a swing bolster sand core fixture, a side frame sand core fixture and a box sand core fixture, wherein each of the swing bolster sand core fixture and the side frame sand core fixture consists of two sets of pneumatic clamping jaws, and a clamping structural form is that one set of pneumatic clamping jaw is fixed, and the other set of pneumatic clamping jaw is a flexible mechanism; and the flexible mechanism has a sealed structure, positive pressure is generated for dust prevention in the sealed structure, and the top of the sealed structure is oiled and lubricated. Compared with a fixture with the conventional structure, the swing bolster sand core fixture adopting the structure of clamping the positions of reinforcing ribs is more stable in clamping; and due to the adoption of internal clamping, a movable block required by the conventional external clamping is eliminated during the sand core manufacture of a customer to lower the sand core manufacture cost of the customer. By a mounting mode for abrasion-proof cushions of the side frame sand core fixture and the box sand core fixture, frictional contact areas are enlarged, the abrasion-proof cushions can be more firmly arranged, and the fixture can more stably and reliably work.

Description

technical field [0001] The invention belongs to casting equipment, and is a three-in-one sealed and flexible core lowering fixture. Background technique [0002] At present, there are relatively few flexible core laying equipment, and manual labor occupies a large proportion. Manually placing the sand cores is inaccurately placed, and the thickness of the produced workpieces is not very uniform, and there will be hidden dangers in the quality of the produced products. At the same time, the work of setting the cores is labor-intensive and the working environment is harsh, which is harmful to the health of workers. In the foundry industry, the design requirements of the core fixture are very strict. If the design is unreasonable, due to the error of the workpiece itself, it will not be able to clamp or the sand core will be damaged. The dust-proof effect of the fixture itself in the prior art is relatively poor, and the wearing parts are replaced relatively frequently. Since...

Problems solved by technology

Manual placement of sand cores is inaccurate, the thickness of the produced workpieces is not very uniform, and there will be hidden dangers in the quality of the products produced; at the same time, the work of setting the cores is labor-intensive and the working environment is harsh, which is harmful to the health of workers.

In the foundry industry, the design requirements of the core fixture are very strict. If the design is unreasonable, due to the error of the workpiece itself, it will not be able to clamp or the sand core will be damaged.

The dust-proof effect of the fixture itself in the prior art is poor, and the replacement of wearing parts is relatively frequent

Since multiple products are often produced on the same production line, fixtures need to be replaced continuously. If the positioning is inaccurate due to the replacement of fixtures, it will cause difficulties for users to use and maintain.
