Description
Technical Field
The utility model belongs to the field of machinery, especially, relate to a disappearance mould drying device.
Background
The lost foam casting is a full-mold casting of a foam plastic mold by adopting a binder-free dry sand combined vacuumizing technology, and is a novel casting method for bonding and combining foam models with similar sizes and shapes of castings into a model cluster, coating refractory paint on the model cluster, drying the model cluster, burying the model cluster in dry quartz sand for vibration molding, pouring the model cluster under negative pressure, gasifying the model, enabling liquid metal to occupy the position of the model, and forming the castings after solidification and cooling. After the refractory coating is coated on the model cluster, the model cluster needs to be placed into a drying box body for drying, the drying temperature is usually 50-55 ℃, the model cluster is easily heated and deformed and even burnt when the drying temperature is too high, and the working efficiency is affected when the drying time is too long when the drying temperature is too low. The existing drying mode of the model cluster is to put the model cluster into drying boxes one by one and then take out the model cluster after reaching the drying time. But different model cluster size is different, and too big the making space too extravagant easily of stoving case, and undersize if, can not adapt to the placing of big model cluster.
SUMMERY OF THE UTILITY MODEL
In order to solve the problem, the utility model discloses a disappearance mould drying device. The utility model discloses simple structure, the preparation is convenient, can be according to the model of disappearance mould cluster size adjustment place the space and avoid getting to put the model cluster and lead to the fact the influence to all model clusters, and guaranteed that the temperature of drying is in all the time and set for the within range, prevented that the high temperature from or cross lowly.
In order to achieve the above purpose, the technical scheme of the utility model is that:
a lost foam drying device comprises a shell, wherein a partition plate is fixed in the middle of the shell to divide the shell into a front box body and a rear box body; a plurality of single boxes are arranged in the front box; the inner side surface of the single box body is formed by movable wall plates, and the movable wall plates are I-shaped and are connected with the partition plates in a front-back sliding manner; a plurality of single box bodies which are adjacent to each other form a box body unit; a box unit door is hinged on the front box body corresponding to each box body unit; a single box body door is hinged on each box body unit door corresponding to the single box body; a plurality of air holes are uniformly distributed on the partition plate; the rear box body is communicated with an air inlet pipe, and an electric regulating valve is installed on the air inlet pipe; the air inlet pipe is sequentially provided with an air pump, a gas-water separator and a heater along the air inlet direction; and a temperature sensor which is in wired or wireless connection with the electric regulating valve is arranged in the rear box body.
In a further improvement, the partition plate is provided with a long hole matched with the movable wall plate.
In a further improvement, the housing is made of a thermal insulation plate.
In a further improvement, the box unit door and the single box body door are both provided with handles.
In a further improvement, each box body unit comprises 2N single box bodies 6, wherein N is a positive integer more than or equal to 2.

Detailed Description
Example 1
The lost foam drying device shown in fig. 1 and 2 comprises a shell 1, wherein a partition plate 2 is fixed in the middle of the shell 1 to divide the shell 1 into a front box body 3 and a rear box body 5; a plurality of single box bodies 6 are arranged in the front box body 3; the inner side surface of the single box body 6 is formed by a movable wall plate 10, and the movable wall plate 10 is I-shaped and is connected with the partition plate 2 in a front-back sliding manner; a plurality of single box bodies 6 adjacent to each other form a box body unit 7; a box body unit door 8 is hinged on the front box body 3 corresponding to each box body unit 7; a single box body door 9 is hinged on each box body unit door 8 corresponding to the single box body 6; a plurality of air holes 11 are uniformly distributed on the partition plate 2; the rear box body 5 is communicated with an air inlet pipe 12, and an electric regulating valve 13 is arranged on the air inlet pipe 12; the air inlet pipe 12 is sequentially provided with an air pump 14, an air-water separator 15 and a heater 16 along the air inlet direction; and a temperature sensor in wired or wireless connection with the electric regulating valve 13 is installed in the rear box body 5.
The partition 2 is formed with an elongated hole 17 to be fitted to the movable wall plate 10. The housing 1 is made of a heat insulating plate. Handles 18 are mounted on both the chest unit door 8 and the chest door 9. Each case unit 7 contains 4 single cases 6 constituting a positive direction.
The utility model discloses application method as follows:
after the model cluster is coated with the fireproof paint, the model cluster is placed in the front box body 3 and is placed in a single box body 6 according to the size of the model cluster, or the movable wall plates 10 are pushed into the rear box body 5 to form a larger placing space or the four movable wall plates 10 are all pushed in to form a larger placing space, and then the single box body door 9 or the box body unit door 8 is closed; starting the air pump 14, the gas-water separator 15 and the heater 16, hot air firstly enters the rear box body 5 and then uniformly enters each single box body through the air holes 11 on the partition plate 2, when the temperature sensor senses that the temperature is higher than a set threshold value, the opening degree of the electric adjusting valve 13 is controlled to be reduced, and when the temperature is lower than the set threshold value, the opening degree is increased, so that the stability of the drying temperature is kept. After a certain model cluster reaches the drying time, the corresponding single box door 9 or box unit door 8 is opened and taken out, so that other model clusters are basically not influenced when the dried model cluster is taken out, or the model cluster in the same box unit 7 is influenced at most, and the influence of a release part on all the model clusters is avoided.
