Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Examples: solves the problems that the purging pipe cannot closely follow the cope flask to purge and the purging pipe needs to be additionally reset after the cope flask descends in the prior art

The utility model provides a ductile cast iron is with following molding box-fitting sweeping device, be used for the blowing before cope flask 1 and drag flask 2 box-fitting, including blowing pipe 3 and vertical movement platform 41, the bottom of vertical movement platform 41 is connected with blowing pipe 3, vertical movement platform 41 erects in the air through a pair of track 4, the both ends of vertical movement platform 41 and track 4 sliding connection, the top of vertical movement platform 41 is connected with rope 6, be provided with fixed pulley 5 above vertical movement platform 41, rope 6 walks around fixed pulley 5, the one end of rope 6 is connected with the top of vertical movement platform 41, the other end is connected with counter weight 7, counter weight 7 can be when vertical movement platform 41 atress pulls vertical movement platform 41 to the upper end of track 4;

The back of the cope flask 1 is provided with a pressing plate 11, and when the cope flask 1 moves downwards, the pressing plate 11 can drive the vertical moving platform 41 and the purging pipe 3 to synchronously move downwards.

Wherein:

The blowing surface of the purge tube 3 overlaps the bottom surface of the cope flask 1.

The purge pipe 3 is provided with a plurality of nozzles 31.

Optionally, one end of the purge tube 3 is connected to a gas source.

The purpose of the synchronous follow-up purge is to give the falling sand a force in the horizontal direction in advance, so that the sand can be blown farther, avoiding falling into the drag flask 2 when encountering somewhat larger gravel during the top purge of the drag flask 2 and the blowing force is insufficient.

In order to control the upward moving speed of the purge tube 3, a certain damping can be added between the vertical moving platform 41 and the track 4, so that the vertical moving platform 41 is prevented from being pulled to a larger speed by the counterweight 7 and then from colliding with the upper end of the track 4.

The use process of this embodiment is as follows:

Step one: turning over the cope flask 1 to press the platen 11 of the cope flask 1 against the vertically movable platen 41 as shown in fig. 2, 3;

step two: starting an air source of the purging pipe 3;

Step three: slowly descending the cope flask 1 and the drag flask 2 to be in close fit with each other, wherein the air source of the purging pipe 3 is not stopped in the slow descending process;

step four: as shown in fig. 4, the cope flask 1 and the drag flask 2 are closed, and the supply of the air source of the purge pipe 3 is stopped;

step five: as shown in fig. 5, the sand box of the completed mold close is moved to a subsequent step;

Step six: as shown in fig. 6, the vertical moving platform 41 is pulled to the upper end of the rail 4 again by the counterweight 7 due to the loss of the downward pressure from the pressing plate 11 by the vertical moving platform 41.
