Description

Technical Field

[0001] The utility model belongs to the technical field of molds, and in particular relates to an industrial valve body mold. Background Art

[0002] During the casting process of the valve body, molten aluminum is poured into the mold cavity. Since the molten aluminum is poured directly into the mold cavity without being filtered, the aluminum oxide scale will enter the mold cavity with the molten aluminum and affect the molding quality of the valve body. Utility Model Content

[0003] The utility model aims to solve the above technical problems at least to a certain extent. To this end, the utility model aims to provide an industrial valve body mold.

[0004] The technical solution adopted by the utility model is:

[0005] An industrial valve body mold comprises an upper mold and a lower mold. The upper mold and the lower mold are closed to form a cavity for molding the valve body and a pouring riser connected to the cavity. A mounting inclined surface is provided at the portion of the lower mold corresponding to the pouring riser. A filter screen is provided on the mounting inclined surface. The filter screen completely covers the pouring riser on the lower mold. A pillow block is provided on the upper mold. A pressing inclined surface matching the mounting inclined surface is provided on the pillow block. A pouring ladle is provided at the pouring riser on the lower mold. The outlet of the pouring ladle is located at the bottom of the filter screen.

[0006] Preferably, the outer end surface of the pillow block is flush with the side of the upper mold with the pouring and rising opening and the side of the lower mold with the pouring and rising opening. The filter net is provided with four guide posts, and the upper mold is provided with guide holes matching the guide posts.

[0007] The beneficial effects of the utility model are:

[0008] The utility model provides an industrial valve body mold. Aluminum liquid passes through a filter screen from a ladle and enters a mold cavity through a pouring riser to be solidified and formed. The filter screen can effectively filter the oxidized scale of the aluminum liquid and prevent the oxidized scale from entering the mold cavity. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention. The components of the embodiments of the present invention generally described and shown in the accompanying drawings herein can be arranged and designed in a variety of different configurations.

[0014] In the present utility model, unless otherwise clearly stipulated and limited, the terms such as "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal connection of two elements.

[0015] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0016] like Figure 1 , Figure 2 and Figure 3 As shown, an industrial valve body mold of the present embodiment includes an upper mold 1 and a lower mold 2. The upper mold 1 and the lower mold 2 are closed to form a cavity for molding the valve body and a pouring spout 3 connected to the cavity. The portion of the lower mold 2 corresponding to the pouring spout 3 is provided with a mounting bevel 4, and a filter screen 5 is provided on the mounting bevel 4. The filter screen 5 completely covers the pouring spout 3 on the lower mold 2. A pillow block 6 is provided on the upper mold 1, and a pressing bevel 7 matching the mounting bevel 4 is provided on the pillow block 6. A pouring ladle (not shown in the figure) is provided at the pouring spout 3 on the lower mold 2, the opening of the ladle faces upward, and an outlet is provided on one side of the opening, and the outlet is located at the bottom of the filter screen 5.

[0017] Four guide posts 8 are arranged on the filter screen 5, and guide holes 9 matching with the guide posts 8 are arranged on the upper mold 1. After the upper mold 1 and the lower mold 2 are closed, the guide posts 8 are located in the guide holes 9, and the filter screen 5 is pressed and fixed by the pillow block 6. The outer end surface of the pillow block 6 is flush with the side of the upper mold 1 provided with the pouring riser 3 and the side of the lower mold 2 provided with the pouring riser 3; the industrial valve body mold is turned over, and the molten aluminum passes through the filter screen from the ladle and enters the cavity through the pouring riser 3 to be solidified and formed. In this process, the filter screen plays the role of filtering residue, which can effectively filter the molten aluminum oxide scale, prevent the oxide scale from entering the cavity, and ensure the quality of the valve body.

[0018] The present utility model is not limited to the above-mentioned optional implementation modes. Anyone can derive other various forms of products under the inspiration of the present utility model. However, no matter what changes are made in the shape or structure, all technical solutions that fall within the scope defined by the claims of the present utility model fall within the protection scope of the present utility model.
