Description

360-degree sand core blanking device

Technical Field

The application belongs to the lost foam field, especially relates to a psammitolite unloader.

Background

In the casting industry, casting technology can be divided into sand casting technology and special casting technology, lost foam and founding belong to sand casting technology, and founding technology has the following defects:

1: the labor intensity is very high, the sand casting is one of the most bitter and dangerous workers, and the physical consumption is very high:

low founding efficiency and only applicable to small pieces, and when the product exceeds 10 kg, the founding efficiency is very low

3. The unfavorable later stage processing of founding product, founding is for the convenience drawing of patterns, and the founding mould all has the tapering, but, the tapering adds to the machining anchor clamps in later stage and holds, mechanical operation has adverse effect

4. The precision of the founding product is low, the founding product, especially some hollow parts and thin-wall parts, the thickness of the product is not uniform, and the method can only be applied to the occasion with low precision

5. The hardness of the founding product is different, founding needs to be wetted by water, the hardness of the founding product is affected by the amount of water, the water is slightly added, the founding product is similar to a heat treatment process, the hardness of the founding product is improved, the product is easy to soften and has different hardness due to too little water, the later mechanical processing automation process is difficult to carry out, a cutter needs to be adjusted ceaselessly, if the hardness difference is too large, the later processing process is difficult to carry out and only can be scrapped,

based on the wagons of workers and fewer farmer workers willing to do founding workers, the founding industry is difficult to find suitable workers, the adoption of the lost foam in the mechanical casting industry is a great trend, however, the lost foam has strict limitation conditions on the process flow, the operation requirement is not mastered, the cost is greatly improved when the lost foam is easily put on the market, the cost of the lost foam is not cheap, and in addition, the feeding speed, the temperature of the casting liquid and the like need to have strict standards,

in the sand core blanking device, the funnel type blanking complete device provided by the original factory is introduced by the applicant unit, a plurality of problems are found quickly,

the sand core blanking device is easy to cause the casting sand to fly upwards, and a water adding process is not adopted, so that correspondingly, after casting liquid enters a casting die, no water vapor is vaporized, the fineness of the casting sand is higher than that of foundry sand in order to improve the casting precision of the foundry sand, but the problem is that the environmental pollution and the health of workers are caused, and as the fineness of the casting sand is high and water is not added, when the casting sand flows down through a funnel, for some large and medium parts, the casting sand is easy to fly upwards due to the fact that a sand outlet of the funnel is higher than the bottom of the casting die, workers complain, and fine sand grains exist on the workshop ground.

2. When the foam molds are adopted, more than one foam mold is used for improving the casting efficiency, the foam molds are divided into two types, the spatial position relation exists or does not exist between the foam molds, for the grouped parts with the spatial position relation, the foam molds are provided with connecting strips, however, if the size of the parts is larger, the blanking funnel opening of a single raspberry part is ensured to be positioned right above the foam mold during the blanking of casting sand, the difficulty is very high, if the sand core is aligned with one side for blanking, the sand core can cause the foam mold to shift, and the product defect or scrap is caused,

3. the vibrating device can prevent the foam product from generating defects, but the vibration value of the vibrating device is required, the vibration value is too large, the foam mould is vibrated away from the position, the product precision problem is easily caused, the casting sand can possibly enter a region which can not enter the sand in the design, so that the sand entering region can not enter the casting liquid, the product defect or scrap is caused, the offset of the foam mould can be aggravated due to the uneven distribution of the casting sand, the vibration value is too low, the sand core gap can not meet the requirement, the sand core gap is too large, the liquid leakage or the surface roughness can not meet the standard, the liquid inlet speed is strictly controlled in the process of feeding the lost casting liquid, the liquid inlet allowance is strictly controlled, the liquid inlet can be insufficient due to the liquid leakage, the liquid inlet allowance is forced to be increased due to the related parameters of the knitting, resulting in increased costs.
