Mounting method of sand box positioning sleeve for casting

Abstract

The invention discloses an installation method of a sand box positioning sleeve for casting. The installation method comprises the installation process that the positioning sleeve is installed on sand box lifting lugs on the two sides of a sand box in a vibration-free knock-in mode. The inlay layer can make up the error of drilling mounting holes in the sand box lifting lugs on the two sides of the sand box, meanwhile, the situation that the positioning sleeve needs to be knocked into the mounting holes in the sand box lifting lugs on the two sides of the sand box is avoided, and the problem that the sand box is prone to being damaged is solved.

Description

Technical Field

[0001] The invention relates to an installation method of a sand box positioning sleeve for casting, belonging to the technical field of sand box installation. Background Art

[0002] In the sand casting process, in order to ensure that the upper and lower sand boxes 1 are accurately positioned and closed, the positioning and closing pins 2 are used to position and close the boxes, so as to ensure the positioning accuracy. Figure 1 As shown. Its working principle is: the sand box ears 11 on both sides of the sand box 1 are drilled with mounting holes, the positioning sleeves 12 are knocked into the mounting holes, and the positioning and closing pins 2 are plugged and positioned with the positioning sleeves 12 of the upper and lower sand boxes 1. Although the upper and lower sand boxes 1 can be accurately positioned and closed, when the positioning sleeves 12 are knocked into the mounting holes of the sand box ears 11 on both sides of the sand box 1, the sand box 1 is easily damaged. Summary of the invention

[0003] In order to solve the above technical problems, the present invention provides a method for installing a positioning sleeve of a casting sand box.

[0004] The present invention is achieved through the following technical solutions.

[0005] The present invention provides a method for installing a flask positioning sleeve for casting, comprising:

[0006] The installation process of installing the positioning sleeve on the sand box lifting ears on both sides of the sand box is realized by a vibration-free knocking method.

[0007] The installation process is as follows: the positioning pins are installed on the template for penetration positioning, the sand box ears on both sides of the sand box are drilled with mounting holes larger than the positioning sleeves, the sand box is placed and installed on the template, the positioning pins penetrate the mounting holes of the sand box ears, a molding sand layer is laid between the sand box ears and the template, the molding sand layer blocks the bottom of the mounting hole of the sand box ears, the positioning sleeves are sleeved on the positioning pins, and there is a casting interval between the positioning sleeves and the mounting holes of the sand box ears;

[0008] Then pour the molten metal into the pouring interval, and the molten metal forms an inlay layer after solidification, and the inlay layer fixes the positioning sleeve on the flask ears on both sides of the flask.

[0009] The beneficial effect of the present invention is that the inlay layer can compensate for the error of drilling the mounting holes of the sand box ears on both sides of the sand box, while avoiding the need to knock the positioning sleeves into the mounting holes of the sand box ears on both sides of the sand box, thereby solving the problem of easily causing damage to the sand box.

[0014] The technical solution of the present invention is further described below, but the scope of protection claimed is not limited to the description.

[0015] like Figures 2 to 3 shown.

[0016] The present invention provides a method for installing a flask positioning sleeve for casting, comprising:

[0017] The positioning and closing pins 2 are installed on the template 3 for penetration positioning, and mounting holes larger than the positioning sleeves 12 are drilled in the sand box ears 11 on both sides of the sand box 1. The sand box 1 is placed and installed on the template 3, and the positioning and closing pins 2 penetrate the mounting holes of the sand box ears 11. A molding sand layer 4 is laid between the sand box ears 11 and the template 3, and the molding sand layer 4 blocks the bottom of the mounting hole of the sand box ears 11. The positioning sleeves 12 are sleeved on the positioning and closing pins 2, and there is a pouring gap 41 between the positioning sleeves 12 and the mounting holes of the sand box ears 11; then, molten metal is poured into the pouring gap 41, and the molten metal forms an inlay layer 42 after solidification. The inlay layer 42 fixes the positioning sleeves 12 on the sand box ears 11 on both sides of the sand box 1, and the sand box 1 is removed from the template 3, and the positioning and closing pins 2 are separated from the template 3, and then the upper and lower sand boxes 1 are accurately positioned and closed by the positioning and closing pins 2.

[0018] After the positioning sleeve 12 is worn, the positioning sleeve 12 can be replaced by removing the inlay layer 42 .

[0019] The inlay layer 42 can compensate for the error of drilling the mounting holes of the flask ears 11 on both sides of the flask 1, and avoids the need to knock the positioning sleeves 12 into the mounting holes of the flask ears 11 on both sides of the flask 1, thereby solving the problem of easily causing damage to the flask 1.
