TECHNICAL FIELD

[0001] The utility model relates to cylinder body die casting structure technical field, especially a kind of die casting mould core structure for air conditioner compressor cylinder body. BACKGROUND

[0002] When the conventional cylinder body is produced using a die casting mold, the mold cavity forming the cylinder body is usually arranged horizontally, and multiple core-pulling structures are used to facilitate the auxiliary forming of the cylinder body shape. This approach greatly increases the manufacturing cost of the mold. To solve the above problem, the mold needs to be improved. When the mold cavity is arranged vertically, the longitudinal depth of the mold cavity is greatly increased, which can cause the produced product to have air shrinkage holes. The main reason for this problem is that the longitudinal depth is large, which can cause poor exhaust. To solve the above problem, the mold needs to be improved. SUMMARY

[0003] The technical problem to be solved by the utility model is to provide a die casting mould core structure for air conditioner compressor cylinder body, which has the characteristics of reducing the manufacturing cost of the mold, improving the quality of the product, facilitating mold opening and part removal, etc.

The upper mold core and the lower mold core are arranged vertically. The front side and the rear side of the upper mold core are respectively provided with a front core-pulling structure and a rear core-pulling structure. The rear end of the front core-pulling structure is provided with a front core-pulling forming block. The front end of the rear core-pulling structure is provided with a rear core-pulling forming block. The front core-pulling forming block and the rear core-pulling forming block are connected, forming a vertically arranged cylindrical cavity. The upper mold core covers the front core-pulling forming block and the rear core-pulling forming block. The middle part of the upper mold core is provided with a downward protruding inner cavity forming column. The inner cavity forming column is arranged at the middle part of the cylindrical cavity.

The rear side of the lower forming cavity is provided with a plurality of lower layer exhaust slag pocket structures. The upper layer exhaust slag pocket structures are located above the rear core-pulling forming block. The lower layer exhaust slag pocket structures are located below the rear core-pulling forming block.

[0005] In this technical solution, the front core-pulling forming block and the rear core-pulling forming block are used to form the outer circle of the cylinder body, greatly reducing the manufacturing cost of the mold, and greatly facilitating mold opening and part removal. The upper layer exhaust slag pocket structures and the lower layer exhaust slag pocket structures are used to facilitate the synchronous air exhaust of the upper end and the lower end of the cylindrical cavity, so that the internal air can be exhausted, avoiding the production of a large number of air shrinkage holes in the product, and improving the quality of the product.

[0006] As a supplement to this technical solution, an exhaust block assembly is installed on the right side of the upper mold core and the lower mold core. A lower exhaust channel that connects with the exhaust block assembly is provided on the upper surface of the lower mold core. The lower exhaust slag bag structure and the upper exhaust slag bag structure are connected by a shallow groove and are connected by a centralized exhaust groove and the lower exhaust channel.

[0007] By setting up a centralized exhaust channel to connect the lower and upper exhaust slag pack structures, internal air can be centrally discharged, improving product quality.

[0008] As a supplement to this technical solution, a gating structure is installed on the front core puller. The gating structure and the upper front side of the cylindrical cavity are connected by a main channel. The main channel is set to facilitate the injection of molten aluminum.

[0009] As a supplement to this technical solution, a front docking rod is installed in each of the four corners of the front core-pulling forming block, and a rear docking rod is installed in each of the four corners of the rear core-pulling forming block. The front docking rods and rear docking rods correspond one-to-one, and the front docking rods and rear docking rods in the same group are in a top-down state. By setting the front docking rods and rear docking rods, the forming of the side docking holes of the product is ensured.

[0010] As a supplement to this technical solution, a ring of hole forming pins is provided on the upper mold core, and the lower end of the hole forming pins corresponds to the upper edge of the cylindrical cavity.

[0011] As a supplement to this technical solution, the inner cavity forming column is provided with several cooling pipes, and each cooling pipe has a cooling pipe joint installed on its upper opening. The cooling pipes are used to internally cool the product.

[0012] Beneficial effects: This utility model relates to a die-casting mold core structure for an air conditioner compressor cylinder. By setting a front core-pulling block and a rear core-pulling block to form the outer ring of the cylinder, the manufacturing cost of the mold is greatly reduced, and the mold opening and part removal are also greatly facilitated. At the same time, by setting an upper venting slag bag structure and a lower venting slag bag structure, the upper and lower ends of the cylindrical cavity are simultaneously vented, so that the internal air can be discharged, avoiding the formation of a large number of shrinkage cavities in the product, and improving the product quality. It has the characteristics of reducing mold manufacturing costs, improving product quality, and facilitating mold opening and part removal. Attached Figure Description
