Description

Technical Field

[0001] This utility model provides a cooling structure for a mold, particularly a point cooling structure for an inner valve body mold. Background Technology

[0002] Currently, when casting castings, multiple adjacent recesses need to be set in certain areas of the casting. When the area where the recesses are set in the casting is thick, the recesses on the mold are all achieved by using individual protrusions. The space for cooling at the protrusion positions is limited, which makes it easy for casting defects to occur in the thicker areas of the casting.

[0003] No technical solutions to the above-mentioned technical problems have been found yet. Summary of the Invention

[0004] In view of the above-mentioned shortcomings of the prior art, the purpose of this utility model is to provide an internal valve body mold cooling structure. The internal valve body mold cooling structure is reasonably designed and is conducive to setting cooling structures at multiple protruding pin positions in close proximity on the mold to overcome casting defects.

[0005] The present invention relates to a cooling structure for an inner valve body mold, characterized in that: it includes an inner valve body mold body and an insert embedded in the inner valve body mold. Several spaced protrusions are integrally protruding from the end face of the insert. Several countersunk channels coaxial with the protrusions are provided in the insert body. The bottom end of the countersunk channel approaches or extends into the protrusion body. A cooling water assembly is inserted into the countersunk channel, and the outlet end of the cooling water assembly extends into the bottom end of the countersunk channel.

[0006] Preferably, the end face of the insert matches the shape of the molded surface of the casting, and the protrusion protrudes from the end face of the insert to form a concave hole on the molded surface of the casting.

[0007] Preferably, the above-mentioned protrusions have three.

[0008] Preferably, the cooling water assembly includes an outer tube and an inner tube inserted inside the outer tube. The first end of the outer tube has an external thread that is threaded to the internal thread of the countersunk hole port. The inner tube extends beyond the outer tube, and the first end of the inner tube extends into the bottom end of the countersunk hole.

[0009] Preferably, the second ends of the outer tube and the inner tube are respectively output to connect with the pipeline outside the inner valve body mold body.

[0010] The working principle of the internal valve body mold cooling structure of this utility model is as follows: By integrally manufacturing several protruding pillars (or protruding pins) on the insert of the internal valve body mold body, sufficient space is provided on the insert to set up countersunk channels for installing cooling water components, so as to achieve cooling of the protruding pillars and the end face of the insert (the forming surface of the casting), thereby improving the cooling effect at this position and overcoming casting defects.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0019] The cooling structure of the inner valve body mold of this utility model includes an inner valve body mold body 1 and an insert 2 embedded in the inner valve body mold. The insert 2 is inserted into the through hole of the inner valve body mold body 1. Several protruding posts 3 are integrally protruding on the end face of the insert 2 at intervals. The number of protruding posts 3 can be two, three or four, etc.

[0020] The insert 2 has several countersunk channels 4 coaxial with the protrusions 3. The number of countersunk channels 4 can be the same as the number of protrusions 3, that is, the countersunk channels 4 and the protrusions 3 are coaxial and correspond one-to-one. Of course, it is also possible that two or three protrusions 3 share one countersunk channel 4.

[0021] The bottom end of the submerged channel 4 is close to or extends into the protruding column body. A cooling water assembly 5 is inserted into the submerged channel, and the outlet end of the cooling water assembly 5 extends into the bottom end of the submerged channel.

[0022] Because several protruding pillars 3 (or protruding pins) are integrally manufactured on the insert 2 of the inner valve body mold body, there is enough space on the insert to set the countersunk channel for installing the cooling water assembly, so as to achieve cooling of the end face (formed surface of the casting) of the protruding pillar and the insert, thereby improving the cooling effect at this position and overcoming casting defects. The protruding pillar 3 forms a concave hole A1 on the casting A.

[0023] The end face 201 of the insert matches the shape of the molded surface of the casting, and the protrusion protrudes from the end face of the insert, thus forming a concave hole on the molded surface of the casting.

[0024] Specifically, the cooling water assembly 5 includes an outer tube 501 and an inner tube 502 inserted inside the outer tube. The first end of the outer tube has an external thread 503 that is threaded to the internal thread 401 of the countersunk hole port. The inner tube extends beyond the outer tube, and the first end of the inner tube extends into the bottom end of the countersunk hole. A countersunk hole communicating with the countersunk hole 4 can be machined in the body of the protrusion. The outer diameter of the inner tube can be smaller than the countersunk hole diameter of the protrusion 3, so that the cooling water can cool the protrusion 3 better.

[0025] The second ends of the outer tube and the inner tube are respectively connected to the pipes outside the inner valve body mold body. The second ends of the outer tube and the inner tube can be located on the surface of the inner valve body mold body 1 away from the forming surface.

[0026] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. For those skilled in the art, the present utility model can have various modifications and variations.
