Description

Technical Field

[0001] The utility model relates to a mold for casting, in particular to a sand casting mold which is easy to position, and belongs to the technical field of mold tooling. Background Art

[0002] Sand casting refers to the use of a mold to create a sand cavity in a sand mold that conforms to the structure of the workpiece. The existing sand box relies on manual boxing to close the upper and lower boxes to prevent box expansion and misalignment. However, the box is stuck in the driving process of the trolley and there is a safety hazard that it will gradually loosen. To solve this problem, we use iron weights to fix the sand box, but the problem that follows is that after closing the box, the upper and lower boxes are prone to misalignment. Utility Model Content

[0003] The technical problem to be solved by the utility model is to overcome the shortcomings of the existing technology and provide a sand tire casting mold that is easy to position, so as to facilitate the rapid positioning of the sand tire, avoid the situation where the qualified rate of castings decreases due to misalignment, improve the qualified rate of castings, and reduce costs.

[0004] The technical solution adopted by the utility model to solve the technical problem is:

[0005] A sand mold mold that is easy to position includes an upper template, a lower template and a casting model. The casting model is respectively provided in the middle of the upper template and the lower template. Countersunk grooves are provided around the upper template, and bosses are provided around the lower template. The positions of the countersunk grooves correspond to the positions of the bosses. Positioning pins are respectively provided in the middle of the two ends of the upper template and the lower template.

[0006] There are three countersunk grooves and three bosses.

[0007] The inner diameter of the countersink is 120 mm, the depth of the countersink is 40 mm, and the draft angle of the countersink is 10°.

[0008] The outer diameter of the boss is 120 mm, the height of the boss is 40 mm, and the draft angle of the boss is 10°.

[0009] The upper template is provided with half of the casting model, and the lower template is provided with the other half of the casting model. The two casting models are combined together to form a complete casting.

[0010] The positive beneficial effects of the utility model are:

[0011] 1. The utility model provides a countersunk on the upper template and a convex platform on the lower template. The two are used in conjunction with each other. The sand box made by using the template can avoid the situation of misalignment when the box is combined, which is convenient for the staff to perform accurate positioning.

[0012] 2. The utility model sets locating pins at both ends of the upper template and the lower template so that the locating pin holes formed on the sand box correspond to the upper and lower locating pins on the equipment, which is convenient for the staff to accurately close the upper and lower sand boxes. At the same time, it improves the qualified rate of castings, is easy to use and simple to operate. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] Figure 1 This is a structural diagram of the upper template of the utility model;

[0014] Figure 2 This is a schematic structural diagram of the lower template of the utility model;

[0015] Among them: 1-upper template, 2-lower template, 3-casting model, 4-counter sink, 5-boss, 6-locating pin. DETAILED DESCRIPTION

[0016] The present invention will be further explained and illustrated below with reference to the accompanying drawings:

[0017] For example, see Figure 1-Figure 2 A sand mold mold that is easy to position includes an upper template 1, a lower template 2 and a casting model 3. The casting model 3 is respectively arranged in the middle of the upper template 1 and the lower template 2, countersunk mouths 4 are arranged around the upper template 1, and bosses 5 are arranged around the lower template 2, and the position of the countersunk mouth 4 corresponds to the position of the boss 5. Positioning pins 6 are respectively arranged in the middle of the two ends of the upper template 1 and the lower template 2.

[0018] There are three countersunk grooves 4 and three bosses 5 .

[0019] The inner diameter of the countersink 4 is 120 mm, the depth of the countersink 4 is 40 mm, and the draft angle of the countersink 4 is 10°.

[0020] The outer diameter of the boss 5 is 120 mm, the height of the boss 5 is 40 mm, and the draft angle of the boss 5 is 10°.

[0021] Half of the casting model is arranged on the upper template 1, and the other half of the casting model is arranged on the lower template 2. The two casting models are combined to form a complete casting.

[0022] In the above description, a countersunk is provided at the upper and lower parts of the left side of the upper template respectively, and a countersunk is provided at the upper part of the right side of the upper template.

[0023] In the above description, a boss is provided on the upper and lower parts of the left side of the lower template respectively, and a boss is provided on the upper part of the right side of the lower template.

[0024] In the above description, the boss and countersink match each other, and the position tolerance is ±0.1mm.

[0025] In the above description, by setting positioning pins at both ends of the upper template and the lower template, a positioning pin hole is formed on the sand box, and the position of the positioning pin hole corresponds to the position of the positioning pin in the lifting device.

[0026] The utility model provides corresponding countersunk grooves and bosses on the upper template and the lower template, and cooperates with the use of positioning pins to avoid the misalignment of the manufactured sand boxes when the boxes are combined, which is convenient for workers to perform accurate positioning, improves the qualified rate of castings, is easy to use and simple to operate.
