Abstract

An air suction structure for DISA offline core frame to prevent the core from falling, including the lower core frame and the lower core frame positioning block, which is characterized in that the lower core frame and the lower core frame positioning block are sequentially arranged on the lower core frame and the lower core frame positioning block. The suction hole, the suction hole of the positioning block of the lower core frame and the suction groove of the positioning block of the lower core frame form a vacuum suction structure. Advantages: The structure has simple shape, smooth ventilation, and is easy to manufacture. The area of the suction groove structure is larger than that of the suction hole structure, which is conducive to the cooperation between the core and the lower core frame, and at the same time avoids the fall of the core and the shape of the mold. If the core is placed unstable, the core laying personnel can also place the core in the core setting frame at one time to avoid repeated placement. It not only reduces the labor intensity of personnel, but also avoids the waste of resources caused by production line delays and the poor size caused by mass production. This structure is suitable for the lower core frame jig. When the lower core frame is matched with the core, it needs to be fixed by vacuum suction. This structure is conducive to vacuum adsorption, especially to prevent the core from falling and being unstable.

Description

A suction structure for DISA offline core frame to prevent core from falling

technical field

The utility model relates to a DISA production line in the foundry industry, in particular to an air suction structure used for a DISA offline core frame to prevent cores from falling.

Background technique

In the current foundry industry, most of the caliper products of the DISA line cannot produce castings with only two templates, and need to be assisted by cores and lower core frame jigs for production. The core needs to be put into the lower core frame fixture and then moved to put the core into half of the sand mold, and then the two halves of the sand mold are closed, moved to the pouring position for pouring, and the core is automatically broken after the cooling is completed. fall off to form a casting. When the core is put into the lower core frame, it is fixed by the vacuum suction method of the suction hole. The suction area of the connection position of the core is small, and it is easy to cause the core to fall or not firm when placed, which will lead to delays in the production line and failure of mass production products. Poor size and waste of resources.

Utility model content

The purpose of the utility model is to provide an air suction structure for DISA offline core frame to prevent the core from falling. Core drop and unstable structure.

The technical scheme of the utility model: an air suction structure used for DISA offline core frame to prevent the core from falling, including the lower core frame and the lower core frame positioning block, which is characterized in that the lower core frame and the lower core frame positioning block Interconnected lower core frame suction holes, lower core frame positioning block suction holes and lower core frame positioning block suction slots are arranged in sequence to form a vacuum suction structure.

The suction groove of the positioning block of the lower core frame of the vacuum suction structure sucks the core placed on the lower core frame.

One end of the suction hole of the lower core frame is connected to a vacuum device, the other end is connected to one end of the suction hole of the positioning block of the lower core frame, and the other end of the suction hole of the positioning block of the lower core frame is connected to the suction groove of the positioning block of the lower core frame. The suction groove of the core frame positioning block is in contact with the core for adsorption.

The suction groove of the positioning block of the lower core frame is a cuboid structure with a suction area in contact with the core of not less than 150 mm ² .

Work process of the present utility model: this structure is used when core is put into lower core frame. The vacuum suction operation starts when the core is placed in the lower core frame. When the core is placed, the vacuum passes through the suction hole of the lower core frame positioning block through the suction hole of the lower core frame and reaches the suction groove of the positioning block of the lower core frame to fix the core. , and then move the lower core frame, put the core into the sand mold and release the vacuum, then the lower core frame returns to the original position for the next round of operation. After the core is in the sand mold, the two halves of the sand mold are clamped, and then moved for pouring. After cooling, the off-line core automatically falls to produce castings.

Advantages of the utility model: 1. The structure has simple shape, smooth ventilation, and is easy to manufacture. Compared with the suction hole structure, the suction groove structure has a larger area, which is beneficial to the cooperation between the core and the lower core frame, and at the same time avoids the If the core is dropped or the core is placed unstable, the core setting personnel can also place the core in the core frame at one time to avoid repeated placement. This not only reduces the labor intensity of personnel, but also avoids resource waste caused by production line delays and dimensional defects caused by mass production. 2. This structure is suitable for the lower core frame fixture. When the lower core frame is matched with the core, it needs to be fixed by vacuum suction. This structure is conducive to vacuum adsorption, especially to prevent the core from falling and being unstable.

detailed description

Embodiment: a kind of air-breathing structure (see Fig. 1, Fig. 2) that is used for the core frame under the DISA line to prevent the core from falling, including the lower core frame 5 and the lower core frame positioning block 3, is characterized in that the lower core frame 5 The lower core frame suction hole 4, the lower core frame positioning block suction hole 2 and the lower core frame positioning block suction groove 1 are arranged successively on the lower core frame positioning block 3, forming a vacuum suction structure.

The suction groove 1 of the lower core frame positioning block of the vacuum suction structure sucks the core placed on the lower core frame 5 .

One end of the suction hole 4 of the lower core frame is connected to a vacuum device, the other end is connected to one end of the suction hole 2 of the positioning block of the lower core frame, and the other end of the suction hole 2 of the positioning block of the lower core frame is connected to the suction hole of the positioning block of the lower core frame Groove 1, the suction groove 1 of the positioning block of the lower core frame is in contact with the core for adsorption.

The suction groove 1 of the positioning block of the lower core frame is a cuboid structure.

In this example, the suction hole of the lower core frame and the positioning block of the lower core frame is The suction groove is 20mm long, 8.2mm wide, 2mm deep, and R4mm. The suction area is increased from 50.265mm ² to 150.265mm ² . It is stable and not easy to fall.

The suction structure of the lower core frame is well applied and fully achieves the desired effect.
