Problems solved by technology

In the traditional technology, the sand poured out of the box will be piled aside and not used for a long time, but the new sand will be used for casting production, which will cause the old sand to be idle, which will occupy space and increase production investment cost

Embodiment Construction

[0020] In order to make the purpose and technical solution of the present invention more clear, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0021] Such as figure 1 As shown, the present invention provides a casting mold sand recycling device, which includes a screening and impurity removal device, a cooling device and a sand delivery device. In this embodiment, the ground is used as a reference, wherein the screening and impurity removal device It is located below the ground, and the cooling device and the sand sending device are located above the ground. The screening and impurity removal device includes a first support frame 1, the top of the first support frame 1 is fixedly equipped with a hopper 2 with an opening facing upwards, the upper end of the hopper 2 is provided with a sieve plate 3, and the upper surface of the sieve plate 3 is connected to the upper surface of the si...

Abstract

The invention relates to a sandy soil recycling device of a casting mold. The device comprises a screening and impurity removing device, a cooling device and a sand feeding device. In the device, large particles and metal impurities in sandy soil used by casting are screened away through the screening and impurity removing device; the sandy soil is cooled through the cooling device; and finally the treated sandy soil is stored for standby application or directly fed into a casting sand box for use through the sand feeding device. According to the device, recycling of the sandy soil is achieved, and the production and investment cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of casting molds, in particular to a sand recycling device for casting molds. 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 to form a model cluster. After brushing refractory paint and drying, it is buried in dry quartz sand for vibration molding. Down pouring, the model is vaporized, the liquid metal occupies the position of the model, solidified and cooled to form a new casting method. After the casting is condensed, the casting can be taken out by releasing the vacuum and turning over the box to pour out the sand. Since the sand is in a state of high temperature during the casting process and will produce some impurities, it cannot be used directly without treatment. of. In the traditional technology, the sand poured out of the box will be piled aside and not used for a long time, but the...
