Description

Technical Field

[0001] This utility model relates to the field of mold technology, specifically to a pump housing mold. Background Technology

[0002] Currently, the production of casings for many instruments and equipment relies on specialized molding dies, which are highly specialized. That is, a single mold typically fits only a specific product model. Even a minor adjustment to the angle of a sidewall rib or the addition of a tiny opening necessitates a complete overhaul and re-fabrication of the entire mold system, leading to prolonged development cycles and significantly increased costs. Therefore, this application aims to provide a pump casing mold with a modular design, allowing for rapid reassembly and partial replacement of related parts. When the product is iterated and only a minor adjustment is made to a particular side, only the mold part corresponding to that side needs to be replaced, while other parts can continue to be used, thereby reducing the development cycle and saving costs. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by providing a pump casing mold that facilitates reassembly and partial replacement.

[0004] The technical solution of this utility model is: a pump housing mold, including a mold blank and a mold core. The mold blank includes a base, a top cover, and an ejector pin mechanism. The upper surface of the base is provided with a lower receiving groove. The lower surface of the top cover is provided with an upper receiving groove. The mold core is divided into an upper mold and a lower mold. Multiple extrusion modules are provided on the mold blank. Each extrusion module includes a driving mechanism and a forming mechanism. The driving mechanism is used to control the forming mechanism to move closer to or further away from the mold core. The forming mechanism is detachably connected to the driving mechanism and is used to cooperate with the mold core to form a complete forming cavity of the product. The mold core is provided with a slot that cooperates with the forming mechanism.

[0005] Furthermore, the upper surface of the top cover is provided with an injection port and a first mounting groove, in which a first extrusion module is provided. The first mounting groove is connected to the upper receiving groove on the top cover, so that the forming mechanism of the first extrusion module can extend into the upper receiving groove.

[0006] Furthermore, a second mounting groove is provided on the front side of the top cover, and a second extrusion module is provided at the second mounting groove; the second mounting groove is connected to the upper receiving groove on the top cover; so that the forming mechanism of the second extrusion module can extend into the upper receiving groove.

[0007] Furthermore, the lower surface of the upper mold is provided with a cavity, and the upper surface of the upper mold is provided with a first slot that communicates with the cavity. The forming mechanism of the first extrusion module cooperates with the cavity through the first slot. The front side of the upper horizontal part is provided with a second slot that communicates with the cavity. The forming mechanism of the second extrusion module cooperates with the cavity through the second slot.

[0008] Furthermore, a third groove and a fourth groove are respectively provided on the left and right sides of the upper mold, and both the third groove and the fourth groove are connected to the cavity.

[0009] Furthermore, a third mounting groove and a fourth mounting groove, which are connected to the lower receiving groove, are respectively provided on the left and right sides of the base; a third extrusion module is provided in the third mounting groove, and a fourth extrusion module is provided in the fourth mounting groove.

[0011] Furthermore, the clamping mechanism includes a limiting rod, a sliding assembly, and a forming mechanism. The forming mechanism is detachably mounted on the sliding assembly for easy replacement.

[0012] Furthermore, the forming mechanism includes a support, with a forming surface designed at the top of the support. This forming surface is used to mate with the mold core to form a complete forming cavity. The main difference between the various extrusion modules lies in their forming mechanisms. The main difference between the clamping mechanism and the extrusion mechanism is that the clamping mechanism does not include a drive mechanism.

[0013] Furthermore, the top cover is provided with a limiting hole that cooperates with the limiting rod.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: The pump housing mold of this utility model is provided with multiple extrusion modules on the mold blank. The extrusion module includes a forming mechanism, which cooperates with multiple slots on the mold core to form a complete product forming cavity. Moreover, the extrusion modules are set on different sides or local positions of the mold. When the iterative product only requires fine-tuning of a certain side or local position, the forming mechanism in the extrusion module at the corresponding position can be replaced or modified separately without redesigning the entire mold system, thereby reducing the R&D cycle and saving costs.
