Embodiment 1

[0016] Embodiment 1: with reference to attached Figure 1-3 . A conical sand making machine rolling mortar wall pouring mold casting process, the height of the molding cavity 2 of the rolling mortar wall in the sand box 1 is smaller than the height of the pouring riser 3 or the volume of the molding cavity 2 is smaller than the volume of the pouring riser 3, or the height The weight of the chromium cast iron rolling wall is less than the weight of the pouring riser. The high chromium cast iron is poured into the rolling wall molding cavity 2 and the pouring riser 3, and then the sand box 1 is hoisted on the high-frequency vibration platform for high-frequency vibration. After vibration and cooling, a high-density high-chromium cast iron rolling mortar wall can be obtained. The inner wall and the outer wall of the mold cavity 2 of the rolling mortar wall are equipped with a plurality of built-in cold irons 4 and external cold irons 5, and the cold irons 4 and 5 are evenly dist...

Embodiment 2

[0017] Embodiment 2: with reference to attached image 3 . A high-frequency vibration platform for the casting mold of the rolling mortar wall of the conical sand making machine. One or more compression springs 103 are respectively placed at the four corners of the rectangular support 101, and the pressure-bearing vibration platform 104 is placed on the compression springs 103. 105 is located in the middle of the back of the pressure-bearing vibration platform 104 and drives the pressure-bearing vibration platform to vibrate at high frequency. A pressing plate 102 is disposed on the lower end surface of the compression spring 103 . Angular baffles 105 are provided at the four corners of the platform surface of the pressure-bearing vibration platform 104 . The pressure-bearing vibration platform 104 is composed of a platen 109, a vertical plate 108 and a four-corner spring top plate 107. The vertical plate 108 is vertically welded on the back of the platen 109, and the four-c...

Embodiment 3

[0018] Embodiment 3: with reference to attached figure 1 . A casting mold for the rolling mortar wall of a conical sand making machine, comprising a sand box 1, the height of the molding cavity 2 of the rolling mortar wall in the sand box 1 is smaller than the height of the pouring riser 3 or the volume of the molding cavity 2 is smaller than the volume of the pouring riser 3, and the pouring A circle of the riser 3 is provided with a plurality of riser spacers 6 . The inner and outer walls of the mold cavity 2 for rolling the wall are provided with a plurality of built-in cold irons 4 and external cold irons 5 . The pouring riser 3 is provided with a plurality of runners 7 .

Abstract

The invention relates to a casting mold of a conical sand maker rolling mortar wall and a casting process capable of achieving the effect of no shrinkage cavity and effectively improving the cast density during casting feeding of the conical sand maker rolling mortar wall. The casting mold is characterized in that the height of a rolling mortar wall forming mold cavity in the sand box is smaller than the height of a casting riser or the volume of the forming mold cavity is smaller than the volume of the casting riser. The casting process comprises the following steps: casting high chromium cast iron into the rolling mortar wall forming mold cavity and the casting riser, then suspending the sand box on a high-frequency vibration platform for high-frequency vibration, and cooling to obtain the high chromium cast iron rolling mortar wall with a high density. The casting mold and the casting process have the advantages that firstly, the wear resistance of the high chromium cast iron rolling mortar wall is effectively improved, and the sand making cost is greatly reduced; secondly, the feeding effect is good, the cast is high in density, and the occurrence of damage phenomenon is avoided; and thirdly, the wear resistance, the shock resistance and the service life are increased by nearly 5 times, and unexpected technical effects are achieved.

Description

technical field [0001] The present invention relates to a conical sand making machine rolling mortar wall pouring mold and a casting process which can obtain no shrinkage cavity and effectively increase the casting density during the casting feeding process of the cone sand making machine rolling mortar wall. Foundry field. Background technique [0002] CN102380579A, the name "a casting method for rolling the wall of the mortar or rolling the wall of the mortar", includes the following steps: 1) Prepare the metal mold: design the shape of the inner and outer metal molds according to the shape of the casting, leave sand covering and machining allowance during the design, and use ordinary Carbon steel moulding, formed by machining; 2) Preparation of sand covering: sand covering is composed of the following raw materials in parts by weight, 80-90 parts of standard sand, 3-5 parts of montmorillonite, 2-2 parts of attapulgite 3 parts, 1-2 parts of iron oxide, 3-5 parts of water,...
