Description

Technical Field

[0001] The utility model relates to the technical field of die casting moulds, in particular to an integral barrel with a vacuum pumping structure. Background Art

[0002] In the die-casting process, the integral barrel is used as a storage and conveying device, and its performance has an important impact on the quality and production efficiency of the castings. However, due to the uneven metal flow, the mold may not be fully filled, thus affecting the quality of the castings. Secondly, bubbles are easily generated during the flow of molten aluminum, and these bubbles will form holes in the castings, affecting the overall strength of the castings, and affecting the purity and quality of the products. The existing integral barrel vacuum holes are generally straight holes. Since the integral barrel does not have enough space in the press position, it is necessary to improve the existing integral barrel structure to meet the current usage requirements.

[0005] Preferably, the groove is V-shaped, which is convenient for cleaning after blockage, facilitates the removal of blockages, and ensures the continuity and stability of production.

[0006] Preferably, the vacuum hole is connected with a straight pipe, the other end of the straight pipe is provided with a bent pipe, and the bent pipe is connected to the vacuum tower, with a simple structure.

[0007] Preferably, both ends of the straight pipe are provided with external threads, and one end of the straight pipe close to the bent pipe is provided with a nut and fixed by the nut.

[0008] Preferably, a threaded hole matching the straight tube is provided at one end of the vacuum hole away from the through hole, which facilitates processing.

The vacuum structure is set on the barrel, and the bubbles in the aluminum liquid are discharged, and the aluminum liquid flows evenly, which can effectively improve the quality and production efficiency of the product. It can solve the problem that the vacuum holes of the existing integral barrel generally use straight holes.
