Embodiment 1

[0022] Example 1, refer to Figure 1-3 , a sand storehouse with cooling function for lost foam casting, which consists of a sand storehouse body 1, a heat absorption mechanism, a feeding hopper 3, two cooling fans 4 and a stirring mechanism;

[0023] The lower outer walls of the two sides of the sand storehouse body 1 are welded with support frames 2 for support. The two support frames 2 are both L-shaped and symmetrically arranged. The bottom outer walls of the two support frames 2 are also bonded with anti-skid pads. The feeding hopper 3 is fixedly connected to the top of the sand storage body 1, the two cooling fans 4 are also fixedly connected to the top of the sand storage body 1, and the bottom of the sand storage body 1 is fixedly connected with a discharge square pipe 14, and the discharge square pipe 14 A discharge valve 15 is installed on the upper wafer;

[0024] The stirring mechanism is specifically composed of the motor 5 fixed on the top outer wall of one of th...

Embodiment 2

[0027] Example 2, refer to figure 1 and Figure 4 , this embodiment is optimized on the basis of Embodiment 1, specifically:

[0028] The heat absorption mechanism is specifically composed of a box body 8 welded on the back outer wall of the sand storehouse body 1, a heat absorption fan 9 fixedly connected to the bottom of the box body 8, a drawer 10 movably installed in the box body 8, and a fixed connection to the bottom of the drawer 10. It is composed of a dustproof net 11, the box body 8 is communicated with the sand storage body 1 through a heat extraction pipe 12, and a material blocking net 13 is fixedly installed on the heat extraction pipe 12, and the material blocking net 13 can prevent the material from being sucked out by the heat-absorbing fan 9;

[0029] In this embodiment, part of the heat is extracted and cooled by the heat absorption mechanism, and the cooling is combined with the cold air blown by the two cooling fans 4, so that the cooling methods of the s...

Abstract

The invention belongs to the technical field of lost foam casting, and particularly relates to a sand bin with a cooling function for lost foam casting, the sand bin comprises a stirring mechanism arranged on a sand bin body, supporting frames are fixed to the outer walls of the lower portions of the two sides of the sand bin body, and a feeding hopper fixedly communicates with the top of the sand bin body; and the top of the sand bin body further fixedly communicates with two cooling fans, the stirring mechanism comprises a motor, a synchronous belt and stirring assemblies distributed at equal intervals, and a heat absorption mechanism is arranged on the back face of the sand bin body. The stirring mechanism and the two cooling fans are used in cooperation, hot casting sand added into the sand bin body is stirred through the stirring mechanism, then the hot casting sand can make uniform contact with cold air blown out by the cooling fans, and therefore the cooling uniformity and quality can be improved; and part of heat is pumped out through the heat absorption mechanism for cooling, and cold air blown out by the two cooling fans is combined for cooling, so that the cooling modes of the sand bin are diversified, and the cooling efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of lost foam casting, in particular to a sand storehouse with cooling function for lost foam casting. Background technique [0002] Lost foam casting (also known as solid casting) is to bond and combine paraffin or foam models similar in size and shape to castings into model clusters. After brushing and drying refractory coatings, they are buried in dry quartz sand and vibrated for modeling. The new casting method is a new casting method in which the model is gasified by pouring down, and the liquid metal occupies the position of the model, and solidifies and cools to form a casting. [0003] In the current sand warehouse, a cooling device needs to be set up to rapidly cool the casting sand after initial demoulding, so that the casting sand can be further recycled. However, the existing sand warehouse has low cooling efficiency when cooling the hot casting sand. The problem of single cooling method and unev...
