Abstract
The utility model relates to the field of casting, provides a novel ceramic pipe inner pouring gate structure capable of effectively avoiding falling of casting sand at an outlet of a ceramic pipe pouring gate, and solves the technical problems that the casting sand at the outlet of the ceramic pipe pouring gate is very easily loosened or falls down when being impacted by a large quantity of molten iron and the fallen casting sand can enter a cavity along with the molten iron to lead to sand holes in castings. The novel ceramic pipe inner pouring gate structure comprises the ceramic pipe pouring gate communicated between a sprue cup on the casting sand and the cavity, wherein a ceramic pipe seat is embedded on the corresponding casting sand at the outlet end of the ceramic pipe pouring gate and comprises a ceramic connecting pipe butted at the outlet end of the ceramic pipe pouring gate; an outer end opening of the ceramic connecting pipe is annularly sleeved with a ceramic cover ring; the ceramic cover ring covers the corresponding casting sand at the periphery of the outlet end of the ceramic pipe pouring gate.
Description
Technical field
The utility model relates to casting field, relates in particular to a kind of Novel ceramic porcelain tube ingate structure that can effectively avoid the molding sand in earthenware running channel exit to come off in the time of cast.
Background technology
In resin sand casting, the general runner of earthenware as molten iron that use, by earthenware, molten iron is introduced to casting mold, but because the sand compaction of earthenware and casting mold die cavity connecting portion is inadequate, therefore in the time being subject to a large amount of molten iron impact, very easily produce loosening or drop phenomenon, the sand falling down can enter die cavity with molten iron, causes occurring on foundry goods a large amount of sand holes.
Summary of the invention
The utility model has mainly been to provide a kind of simple in structure, the Novel ceramic porcelain tube ingate structure that can effectively avoid the molding sand in earthenware running channel exit to come off, having solved the molding sand when earthenware running channel exit existing in prior art is subject to very easily producing and becoming flexible or drop when a large amount of molten iron impact, the molding sand coming off can enter die cavity with molten iron, causes foundry goods to occur the technical problem of sand hole etc.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of Novel ceramic porcelain tube ingate structure, comprise the earthenware running channel being communicated with between cup and die cavity on sand mold, on sand mold corresponding to the described earthenware running channel port of export, be embedded with ceramic tube seat, ceramic tube seat comprises the ceramic tube connector that is docked at the earthenware running channel port of export, external port upper ring cap at ceramic tube connector has ceramic shroud ring, and ceramic shroud ring ladle cover is on sand mold corresponding around the earthenware running channel port of export.By the ceramic tube seat of port of export docking at earthenware running channel, due to the external port of ceramic tube seat stretch out and ladle cover at earthenware running channel Exit-edge along on corresponding sand mold, in the time that a large amount of molten iron are gone out earthenware running channel, the molding sand of ladle cover in ceramic tube seat can not produce loosening or drop phenomenon, simple in structure, and avoided the sand hole of cast phenomenon causing thus.
As preferably, described ceramic tube seat is the integral structure that axial cross section is " T " font.Integral structure, intensity is high, easy-formation processing.
As preferably, the caliber of described ceramic tube connector equates with the caliber of earthenware running channel, and the thickness of ceramic shroud ring is 4 to 6 times of ceramic tube connector wall thickness.In the time that the internal-and external diameter of ceramic tube connector equates with the internal-and external diameter of earthenware running channel, connection and the sand mold of being convenient to both are made.
As preferably, described ceramic tube seat is inlaid in sand mold, and the outer face of ceramic shroud ring is mutually concordant with corresponding sand mold surface.When pottery shroud ring is mutually concordant with sand mold surface, ensure the integrality of foundry goods shape.
As preferably, be wound with adhesive tape outward at the docking port of described ceramic tube connector and earthenware running channel.Adhesive tape connects, simple and convenient.
Therefore, a kind of Novel ceramic porcelain tube ingate structure of the present utility model has following advantage: by the port of export docking ceramic tube seat at earthenware running channel, the Structure Decreasing that it is special the impact strength of molten iron to earthenware running channel and sand mold die cavity contact site, thereby greatly reduce the risk that molding sand becomes flexible, comes off, avoid sand hole of cast phenomenon, ensured the quality of foundry goods.
brief description of the drawings:
Fig. 1 is the structural representation of a kind of Novel ceramic porcelain tube of the utility model ingate structure;
Fig. 2 is the enlarged drawing at the place of A shown in Fig. 1.
detailed description of the invention:
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment:
As shown in Figure 1, a kind of Novel ceramic porcelain tube ingate structure of the present utility model, comprise the earthenware running channel 2 between the die cavity 6 being communicated with in cup 5 and sand mold 1 outside sand mold 1, on sand mold 1 corresponding to earthenware running channel 2 ports of export, setting-in the ceramic tube seat 3 that an axial cross section is " T " font, it comprises the ceramic tube connector 31 that is docked at earthenware running channel 2 ports of export, pottery tube connector 31 equates with the internal-and external diameter of earthenware running channel 2, seam at the two is being wound around adhesive tape 4 outward, outside the external port of ceramic tube connector 31 integral type stretch out form a ceramic shroud ring 32, pottery shroud ring 32 ladle covers are on sand mold 1 corresponding to earthenware running channel 2 port of export edges, the thickness of pottery shroud ring 32 is 5 times of ceramic tube connector 31 wall thickness, and the outer face of ceramic shroud ring 32 is mutually concordant with corresponding sand mold 1 surface.
Specific embodiment described herein is only to design of the present utility model explanation for example.The utility model person of ordinary skill in the field can make various amendments or supplements or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
