Description
Technical Field
The utility model relates to the field of dies, in particular to a core box structure for forming a cast platform on a pipe fitting.
Background
In ductile iron pipe fittings, the information bar on the pipe fitting is an important component of the graphite cast iron pipe fitting; because the information bar on the pipe fitting can clearly mark the specification and the production date of the pipe fitting, the information bar plays a very important role in the use and installation process and the follow-up tracking of the pipe fitting.
In actual design, the information bars are generally arranged on a cast-word platform on the ball-milling cast iron pipe fitting; that is, a casting platform is usually arranged at the intersection of the main pipe and the branch pipe of the traditional ductile cast iron equal-diameter three-way pipe fitting to play a role in reinforcement.
The position of the cast-word platform of the traditional nodular cast iron pipe fitting is easy to generate a shrinkage defect during casting molding, and the appearance quality of the pipe fitting is affected.
In order to reduce the collapse defect rate of the cast-word platform, an air needle needs to be added on the cast-word platform, so that the work load of pipe shot blasting and polishing is increased, and the collapse defect cannot be thoroughly eliminated.
So in order to reduce or avoid the collapse defect rate when the cast word platform is poured; there is a need for improvements to existing production processes or production equipment.
Disclosure of Invention
The utility model aims to provide a core box structure capable of reducing the casting shrinkage defect rate of a casting platform.
In order to achieve the above purpose, the technical scheme adopted by the utility model is as follows:
the core box structure for forming the cast-character platform on the pipe fitting comprises a core box body, wherein a platform sinking groove is formed in the core box body.
The depth of the platform sink is the same as the wall thickness of the pipe fitting to be cast.
The connection part of the platform sinking groove and the core box body adopts arc-shaped surface transition.
The platform sinking groove is a semicircular groove.
The core box body comprises a longitudinal pipe fitting forming shell and a transverse pipe fitting forming shell, and the longitudinal pipe fitting forming shell and the transverse pipe fitting forming shell are mutually perpendicular; the platform sink is disposed at the intersection of the longitudinal tube forming shell and the transverse tube forming shell.
The width of the platform sink groove is smaller than the outer diameter of the longitudinal pipe fitting forming shell; the platform sinking grooves are symmetrically arranged relative to the central axis of the longitudinal pipe fitting forming shell.
The utility model has the advantages that:
the utility model discloses a core box structure for forming a cast-character platform on a pipe fitting; the core box structure disclosed by the utility model can form the casting platform on the pipe fitting, so that the pipe fitting information of the pipe fitting after casting can be conveniently marked later.

The contents of the drawings and the marks in the drawings of the present specification are briefly described as follows:
fig. 1 is a schematic structural view of the present utility model.
The labels in the above figures are:
1. the core box body, 2, the platform sinking groove, 21 and the arc surface.
Detailed Description
The following detailed description of the utility model refers to the accompanying drawings, which illustrate preferred embodiments of the utility model in further detail.
The core box structure for forming the cast-character platform on the pipe fitting comprises a core box body 1, wherein a platform sinking groove 2 is arranged on the core box body 1; the utility model discloses a core box structure for forming a cast-character platform on a pipe fitting; the core box structure disclosed by the utility model can form the casting platform on the pipe fitting, so that the pipe fitting information of the pipe fitting after casting can be conveniently marked later.
In addition, the core box structure disclosed by the utility model is mainly convenient for forming the casting platform on the pipe fitting during subsequent pipe fitting casting, and is convenient for forming the casting platform on the pipe fitting.
Further, in the utility model, the depth of the platform sink 2 is the same as the wall thickness of the pipe fitting to be cast; through the design, the wall thickness of the cast-word platform of the produced pipe fitting tends to be uniform, and casting hotknots are eliminated; thereby fundamentally solving the defect of shrinkage of the casting platform of the equal-diameter three-way pipe fitting.
Furthermore, in the utility model, the joint of the platform sinking groove 2 and the core box body 1 adopts arc-shaped surface transition; the utility model not only facilitates the demolding of the sand core through the transition of the arc-shaped surface, but also enables the transition between the cast-character platform and the pipe fitting which are formed by subsequent casting to be equivalent to the transition of the arc-shaped surface, and avoids the stress concentration at the joint of the cast-character platform and the pipe fitting body.
Further, in the utility model, the platform sinking groove 2 is a semicircular groove; by the arrangement, the edge of the cast-word platform is reduced, and casting stress at the edge of the cast-word platform is avoided.
Further, in the utility model, the core box body 1 comprises a longitudinal pipe molding shell 11 and a transverse pipe molding shell 12, wherein the longitudinal pipe molding shell 11 and the transverse pipe molding shell 12 are mutually perpendicular; the platform sinking groove 2 is arranged at the intersection of the longitudinal pipe molding shell 11 and the transverse pipe molding shell 12; by the arrangement, the cast-character platform not only can be used for marking the pipe fitting information in the subsequent use, but also can increase the structural strength of the joint of the longitudinal pipe and the transverse pipe of the cast-character platform.
Further, in the utility model, the width of the platform sinking groove 2 is smaller than the outer diameter of the longitudinal pipe fitting forming shell 11; the platform sinking grooves 2 are symmetrically arranged relative to the central axis of the longitudinal pipe fitting forming shell 11; by the arrangement, the utility model ensures that the cast-character platform and the longitudinal pipe fittings have stable connection relation, and the cast-character platform cannot exceed the longitudinal pipe fittings to be arranged, so that the arrangement of the cast-character platform with transitional protruding pipe fittings is avoided; in addition, the platform sinking grooves 2 are arranged along the central axis of the longitudinal pipe fitting forming shell 11, so that the casting platform after the follow-up casting is symmetrically arranged along the central axis of the longitudinal pipe fitting.
It is obvious that the specific implementation of the present utility model is not limited by the above-mentioned modes, and that it is within the scope of protection of the present utility model only to adopt various insubstantial modifications made by the method conception and technical scheme of the present utility model.
