Problems solved by technology

As the main power equipment, explosion-proof motors are usually used to drive pumps, fans, compressors and other transmission machinery. The explosion-proof end covers of explosion-proof motors are all produced by casting. The existing castings are generally common sand casting and metal mold casting. There are two methods. For sand casting, it is time-consuming to make the mold. The mold itself cannot be reused and must be destroyed to obtain the finished product. In metal mold casting, although the mold can be reused, it is heavy before and after pouring. It is convenient to carry and move it, and it needs to be preheated before pouring, which will increase the labor intensity of labor

Embodiment 1

[0043] Such as figure 1 , figure 2 , image 3 , Figure 5 , Figure 6 , Figure 7 , Figure 8 As shown, pouring mechanism 3 comprises lifting cylinder 31, pouring trough 32, pouring frame 33, pouring cylinder 34, and lifting cylinder 31 fixing parts are connected to frame 6 top by bolt, pouring frame 33 is arranged on lifting cylinder 31 telescopic parts, pouring trough The upper end of 32 is connected to the lower end of pouring frame 33 through bearings, the fixed part of pouring cylinder 34 is set on the other side of pouring frame 33, the telescopic part of pouring cylinder 34 is set on the other side of pouring trough 32, and the telescoping part of lifting cylinder 31 is used to push the pouring frame 33 to drive The pouring trough 32 and the pouring cylinder 34 move downward, and the telescoping part of the pouring cylinder 34 drives the pouring trough 32 to turn over with the lower end of the pouring frame 33 as the center, thereby pouring the metal liquid inside...

Embodiment 2

[0046] Such as Figure 4 As shown, the difference between Embodiment 2 and Embodiment 1 is that the turning mechanism 5 includes a turning seat 51, a turning motor 52, a sprocket 513, and a chain 514. The end of the seat 51 is connected to the frame 6 in rotation, and the turning motor 52 is connected to the rear side of the frame 6 by bolts and is positioned on the turning seat 51 upper side. 51, the chain 514 is arranged on the outside of the sprocket wheel 513, and two turning seats 51 are used to support the front and rear ends of the forming frame 11. The forming frame 11 is turned over to switch between the first mold 13 and the second mold 14 for pouring.

Abstract

The invention discloses a casting forming device for producing an explosion-proof end cover for an explosion-proof motor. The casting forming device comprises a pouring mechanism used for pouring molten metal liquid, a preheating mechanism used for preheating a motor end cover mold, a turnover mechanism used for driving the pouring mold to rotate and a rack, and the pouring mechanism is located above the rack. The forming frame and the supporting base are used for supporting and fixing the six first molds and the six second molds on the outer side of the forming frame and the supporting base, the rotating forming frame is used for driving the six first molds and the six second molds to conduct alternate pouring, and therefore the casting efficiency of the end cover is improved, the telescopic part of the locking air cylinder is used for driving the locking frame to move front and back in the forming frame, and the casting efficiency of the end cover is improved. Therefore, the locking seats on the lower sides of the first mold and the second mold are locked in a matched mode, then it is guaranteed that the first mold and the second mold are kept perpendicular to the plane of the outer side of the forming frame in the rotating process, and then casting forming is facilitated.

Description

technical field [0001] The invention relates to the production field of explosion-proof motors, in particular to a casting molding device for producing explosion-proof end covers for explosion-proof motors. Background technique [0002] Explosion-proof motor is a kind of motor that can be used in flammable and explosive places, and does not generate electric sparks during operation. Explosion-proof motors are mainly used in coal mines, oil and gas, petrochemical and chemical industries. In addition, it is also widely used in textile, metallurgy, city gas, transportation, grain and oil processing, papermaking, medicine and other departments. As the main power equipment, explosion-proof motors are usually used to drive pumps, fans, compressors and other transmission machinery. The explosion-proof end covers of explosion-proof motors are all produced by casting. The existing castings are generally common sand casting and metal mold casting. There are two methods. For sand cas...
