[0001] This utility model belongs to the field of casting mold technology, and in particular relates to a pump body casting mold with quick mold change. Background Technology

[0002] Pump casting molds are specialized casting tools used to produce pump parts (such as pump bodies, pump covers, impellers, etc.). Their core function is to form liquid metal through a mold cavity.

[0003] Currently, when using casting molds, traditional mold changes require equipment shutdown, and the fixed mold structure limits the production capacity of a single machine, affecting the overall production cycle. In addition, the internal parts are easily damaged by alternating high and low temperatures, leading to cracks and overall damage.

[0004] To address the aforementioned issues, this application proposes a pump body casting mold with rapid mold changing capability. Utility Model Content

[0005] The purpose of this invention is to provide a pump body casting mold with quick mold change, which solves the problems mentioned in the background art.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0034] Please see Figure 1-4 As shown, this utility model is a pump body casting mold with quick mold change, including a lower mold base 1 and an upper mold base 2, and a fixing seat 3 is provided inside the lower part of the lower mold base 1;

[0035] The lower mold base 1 consists of two symmetrical bases, which are symmetrically distributed on both sides of the fixed base 3 and can be separated in the front and back. The lower mold base 1 has an inner cavity 12, and a mold core 4 is detachably installed inside. After the two bases of the lower mold base 4 are separated in the front and back direction, the mold core 4 is exposed, thereby achieving the function of mold changing.

[0036] The bottom of the mold core 4 has a cylindrical boss 41 extending downwards. Both the front and rear sides of the boss 41 are fixed with protrusions 411, and the outer side of the protrusions 411 is a planar structure.

[0037] The protrusion 411 is slidably installed on the slide rail 33 above the fixed base 3, so that the mold core 4 can be directly taken out upward. When the adjacent lower mold bases 1 are merged, the protrusion 411 is engaged in the slot 14 at the bottom of the inner cavity 12.

[0038] Furthermore, a coaxial positioning groove 13 is provided at the bottom of the inner cavity 12. After the two positioning grooves 13 are joined together, a circular through groove is formed. The slot 14 is located on the side of the adjacent positioning grooves 13 that is far away from each other, corresponding to the protrusion 411 on the outer side of the boss 41.

[0039] Furthermore, when adjacent lower mold bases 1 merge, the inner side of the slot 14 is flush with the inner side of the slide 33, which enables the mold core 4 to move in a directional manner when moving within the slide 33, preventing deflection. Thus, when adjacent lower mold bases 1 merge, the outer circular surface of the mold core 4 is used to automatically guide and position the mold core 4, causing it to move to a state coaxial with the inner cavity 12.

[0040] Furthermore, side plates 31 extend from the bottom front and rear sides of the fixed base 3, located below the lower mold base 1, to support the lower mold base 1.

[0041] Furthermore, a transverse drive unit 32 is fixedly installed on the front and rear sides of the fixed base 3. An electric telescopic device is preferred, but other mechanisms that can drive the lower mold base 1 to move parallel in the front and rear direction can also be used. The transverse drive unit 32 is located inside the side grooves 11 at the bottom of the left and right sides of the lower mold base 1. The movable end of the transverse drive unit 32 is fixedly connected to the side end face of the side groove 11 away from the fixed base 3.

[0042] Furthermore, a sliding groove 15 is provided on the bottom of the adjacent side of the adjacent lower mold base 1, which runs through the left and right sides. Its upper end is connected to the inner cavity 12 through the positioning groove 13 and the slot 14. The sliding groove 15 is also used to avoid the fixed base 3. The upper side walls of the slide 33 are adjacent to the top surface of the sliding groove 15.

[0043] It is understandable that this utility model can achieve rapid mold changing after the workpiece is cast and formed, avoiding downtime to achieve continuous casting operations, and can also automatically position the mold core 4. The structure is simple and convenient to use.

[0044] A specific application of the operation process of this embodiment is as follows: In use, the heated mold core 4 is first placed on the fixed base 3, and the sliding connection between the protrusion 411 and the slide 33 is used to push it into the interior of the lower mold base 1. Then, the transverse drive unit 32 drives the adjacent lower mold base 1 to merge, and the inner cavity 12 automatically connects with the outer wall of the mold core 4, thereby driving it to automatically slide to the coaxial position until the protrusion 411 is engaged in the interior of the slot 14 to complete the assembly. After the workpiece is cast, the transverse drive unit 32 is directly driven to separate the adjacent lower mold base 1 so that the mold core 4 is placed outside, and can be taken out by pushing it with an external mechanism. This forms a cycle that is repeated, which is suitable for continuous casting production operations.
