Description

Technical Field

[0001] This utility model belongs to the field of casting mold technology, specifically a casting mold for precision casting that is easy to demold. Background Technology

[0002] Molds refer to various molds and tools used in industrial production to obtain the desired products through methods such as injection molding, blow molding, extrusion, die casting or forging, smelting, and stamping. In the process of stamping and forming castings, upper and lower molds need to cooperate to form the casting. In the precision casting process, molds occupy a very important position.

[0003] Existing molds mainly consist of an upper mold and a lower mold. In use, the upper mold and the lower mold are installed with a hydraulic drive structure and a base, respectively. Under the action of the hydraulic drive structure, the upper mold can be driven to move downwards to assist the lower mold in the casting and shaping process.

[0004] However, in actual use, after the casting is produced, it needs to be removed from the mold. During this process, the casting takes a long time to cool down and is prone to burns if it is not completely cooled. Also, manual removal can easily lead to uneven force during separation, which can damage the casting. This is very inconvenient. Utility Model Content

[0025] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0026] like Figure 1-4 As shown, this utility model provides a technical solution: a casting mold for precision casting that is easy to demold, including a lower mold 1 and an upper mold 2. By setting the upper mold 2 and the lower mold 1, casting of casting parts can be assisted. The lower mold 1 is provided with an auxiliary demolding structure 3. An auxiliary buffer structure 4 is provided between the upper mold 2 and the lower mold 1. The auxiliary demolding structure 3 includes a heat dissipation groove 31. Under the action of the heat dissipation groove 31 and other structures, it can cooperate with other components to provide auxiliary heat dissipation. The heat dissipation groove 31 is opened on the inner wall of the lower mold 1. An auxiliary slot 32 is opened on the top of the heat dissipation groove 31. The auxiliary slot 32 can be assisted in locking and fixing with the auxiliary slot block 33. The auxiliary buffer structure 4 includes a fixing rod 41. The bottom end of the fixing rod 41 is fixedly connected to the lower mold 1. The fixing rod 41 can cooperate with other components to provide auxiliary buffering.

[0027] Specifically, such as Figures 3-4As shown, an auxiliary card plate 34 is engaged with the inner wall of the auxiliary card slot 32. An auxiliary card block 33 is fixedly connected to the bottom of the auxiliary card plate 34. The auxiliary card block 33 engages with the inner wall of the heat dissipation groove 31. The auxiliary card block 33 can be auxiliaryly engaged and fixed with the heat dissipation groove 31. A threaded rod 35 is rotatably connected to the bottom of the outer surface of the auxiliary card block 33. The threaded rod 35 is rotatably set on the bottom inner wall of the lower mold 1. An operating block 36 is fixedly connected to the bottom end of the outer surface of the threaded rod 35. The operating block 36 can drive the threaded rod 35 to rotate, which in turn can drive the auxiliary card block 33 to move. The outer surface of the auxiliary card block 33... A limiting rod 37 is fixedly connected to the bottom. The limiting rod 37 is slidably set on the bottom inner wall of the lower mold 1. The limiting rod 37 can limit the auxiliary locking block 33, so that the auxiliary locking block 33 can be driven to move by the threaded rod 35. Several first heat dissipation holes 39 are opened on both sides of the lower mold 1. Several first heat dissipation holes 39 are equidistantly arranged on the outer surface of the lower mold 1. Two rows of second heat dissipation holes 38 are symmetrically opened at the bottom of the lower mold 1. The first heat dissipation holes 39 can cooperate with the second heat dissipation holes 38 to assist in heat dissipation. The second heat dissipation holes 38 are equidistantly arranged along the bottom outer surface of the lower mold 1.

[0028] Specifically, such as Figure 2 As shown, a sliding cylinder 43 is slidably connected to the top of the fixed rod 41, and a return spring 45 is sleeved on the outer surface of the fixed rod 41. The return spring 45 can cooperate with the sliding cylinder 43 and other components to provide auxiliary buffering. The two ends of the return spring 45 are fixedly connected to the outer surface of the sliding cylinder 43 and the lower mold 1, respectively. A circular baffle 44 is fixedly connected to the top of the outer surface of the sliding cylinder 43. An auxiliary circular hole 42 is opened at the bottom of the upper mold 2. The auxiliary circular hole 42 can cooperate with the circular baffle 44 to provide auxiliary buffering.

[0029] The working principle of this utility model is as follows:

[0030] S1. When the upper mold 2 and the lower mold 1 are casting, the circular baffle 44 can move to the inner wall of the auxiliary circular hole 42, so that the circular baffle 44 touches the bottom, which can drive the sliding cylinder 43 to slide on the outer surface of the fixed rod 41, which can drive the return spring 45 to deform.

[0031] S2. After casting is completed, the heat dissipation groove 31 can work with the first heat dissipation hole 39 and the second heat dissipation hole 38 to assist in heat dissipation, thereby improving the cooling efficiency of the casting inside the lower mold 1.

[0032] S3. At this time, rotate the operating block 36 so that the threaded rod 35 can drive the auxiliary clamping block 33 and the auxiliary clamping plate 34 to move, thereby separating the auxiliary clamping plate 34 from the auxiliary clamping groove 32, and thus ejecting the casting object from the lower mold 1.

[0033] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0034] The preferred embodiments of this patent have been described in detail above. However, this patent is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this patent.
