Trolley for casting sand cores

Abstract

The invention provides a trolley for casting sand cores. The trolley comprises a trolley body, wherein the trolley body is provided with withdrawal trays and sliding rails, sliding chutes matched with the sliding rails are formed in the withdrawal trays, the withdrawal trays are connected with sliding passages of the trolley body, the trolley body is at least provided with two layers of withdrawal trays, foam boxes are arranged in the withdrawal trays, grooves with shapes consistent with the shape of a sand mould are formed in the foam boxes, the sand cores are arranged in the grooves of the foam boxes, so as to be safe and reliable, and prevent incompleteness caused by the collision between the sand cores, a universal wheel is arranged at the lower end of the trolley body, a buffer spring is arranged between the trolley body and the universal wheel to achieve damping of the trolley body, and well prevent the impact or collision on the sand cores in the process of moving. The trolley provided by the invention has the beneficial effects that the trolley for casting sand cores provided by the invention is simple in structure, reasonable in design and good in stability, and the sand cores can be conveniently stored, the impact or collision on the sand cores in the process of moving can be alleviated, and the workload of workers can be lightened.

Description

technical field [0001] The invention relates to the field of smelting alloy casting, in particular to a trolley for casting sand cores. Background technique [0002] Casting refers to the processing method of melting solid metal into liquid and pouring it into a mold of a specific shape, and waiting for it to solidify and form. Ordinary sand casting uses the sand core as the mold material. The shape of the sand core is the key. The precision of the casting and the economic effect of the entire production process mainly depend on this process. Since the sand core will be broken, cracked or incomplete after encountering impact or collision, the scrap rate will increase, which not only wastes costs, but also affects normal production. Therefore, the storage of sand cores becomes very important. In actual operation, ordinary flat trays are used to store sand cores, which requires too much work intensity for the staff, and they must be very careful, which increases the extra wo...
