Abstract
An integrated H-shaped four-way connecting pipe comprises an H-shaped four-way body. A left-upper connecting pipe, a right-upper connecting pipe, a left-lower connecting pipe, a right-lower connecting pipe and a middle connecting pipe are arranged in the four-way body. The integrated H-shaped four-way connecting pipe is characterized in that a hollow pipe made of stainless steel materials is arranged in the middle connecting pipe, concave arc openings are formed in the two ends of the hollow pipe, and the concave arc openings are in contact with a core pulling outer wall in an injection mould. The hollow pipe made of the stainless steel materials is used as an insert first to be arranged in the mould, the concave arc openings formed in the two ends of the hollow pipe are in contact with the core pulling outer wall of the injection mould, after the four-way connecting pipe is formed in an injection mode, the outer wall of the hollow pipe forms the middle connecting pipe, the left-upper connecting pipe, the right-upper connecting pipe, the left-lower connecting pipe and the right-lower connecting pipe are formed outside a circular core pulling part, the circular core pulling part is pulled off during mould opening, the hollow pipe is still left in the middle connecting pipe, core pulling is of no need, the H-shaped four-way connecting pipe is good in integrity, attractive in appearance, the hollow pipe has the effect that the intensity of a whole structure is enhanced, and service life is guaranteed.
Description
Technical field
The utility model relates to the four-way connecting tube, particularly relates to integrated type H type four-way connecting tube.
Background technique
Common three-way pipeline connects, it is modal a kind of pipe fitting in industry and the domestic water, but for the special occasions such as thermal source pump take underground heat as the energy, the structure that the connection of pipe fitting needs is relatively more complicated, especially narrow space at the bottom of ground, need constantly to simplify to install, and sealing requirements is higher, so H type four-way just is being based on the connection pipe fitting that the thermal source pump needs.Existing H type four-way connecting tube during fabrication, because the middle connecting tube of H type four-way connecting tube can't be loosed core, usually two symmetrical three-way pipes about adopting first injection mould to make respectively, between two three-way pipes, make its H type four-way connecting tube that connects into an integral body by a connecting tube or with glue, adopt the continuous component of connecting tube many, make, install trouble, cost of production is high, and adopt glue bonding, and poor reliability, workman's labor intensity when bonding with glue is large.
Summary of the invention
The purpose of this utility model is the shortcoming that exists in order to overcome prior art, provides a kind of easily manufactured, product good integrity, beautiful shape, the integrated type H type four-way connecting tube that structural strength is high.
The technological scheme of the utility model integrated type H type four-way connecting tube is: comprise H type four-way body, in the four-way body, be shaped with upper left connecting tube, upper right connecting tube, lower-left connecting tube, bottom right connecting tube and middle connecting tube, it is characterized in that: be provided with the hollow tube that stainless steel material is made in the described middle connecting tube, be shaped with the concave arc mouth at hollow tube two, the concave arc mouth contacts with the outer wall of loosing core in the injection mould.
The utility model discloses a kind of integrated type H type four-way connecting tube, when injection mould is made the four-way connecting tube, the hollow tube that stainless steel material is made is arranged in the mould as inserts, be shaped with the concave arc mouth at two of hollow tube, concave arc mouth and the circle of the injection mould outer wall of loosing core contacts, the four-way connecting tube is after molding and forming like this, form middle connecting tube at the hollow tube outer wall, the circle outer formation of loosing core is upper left, upper right, the lower-left, the bottom right connecting tube, during die sinking, with upper left, upper right, the lower-left, circle in the connecting tube of bottom right looses core, and hollow tube is still stayed in the middle connecting tube, need not to loose core, easily manufactured, H type four-way connecting tube good integrity, beautiful shape, and overcome existing in the technical barrier that can't loose core of connecting tube place, and the hollow tube made of stainless steel material can play and strengthen integrally-built intensity, guarantees working life.

Fig. 1 is the structural representation of the utility model integrated type H type four-way connecting tube;
Fig. 2 is that the master of hollow insert looks schematic diagram;
Fig. 3 is the A-A direction schematic cross-section of Fig. 2.
Embodiment
The utility model relates to a kind of integrated type H type four-way connecting tube, such as Fig. 1-shown in Figure 3, comprise H type four-way body 1, in the four-way body, be shaped with upper left connecting tube 11, upper right connecting tube 12, lower-left connecting tube 13, bottom right connecting tube 14 and middle connecting tube 15, it is characterized in that: be provided with the hollow tube 2 that stainless steel material is made in the described middle connecting tube 15, be shaped with concave arc mouth 21 at hollow tube two, the concave arc mouth contacts with the outer wall of loosing core in the injection mould.When injection mould is made the four-way connecting tube, the hollow tube 2 that stainless steel material is made is arranged in the mould as inserts, be shaped with concave arc mouth 21 at two of hollow tube, concave arc mouth and the circle of the injection mould outer wall of loosing core contacts, the four-way connecting tube is after molding and forming like this, form middle connecting tube 15 at the hollow tube outer wall, the circle outer formation of loosing core is upper left, upper right, the lower-left, bottom right connecting tube 11,12,13,14, during die sinking, with upper left, upper right, the lower-left, circle in the connecting tube of bottom right looses core, and hollow tube 2 is still stayed in the middle connecting tube 15, need not to loose core, easily manufactured, H type four-way connecting tube good integrity, beautiful shape, and overcome the technical barrier that can't loose core in existing middle connecting tube 15 places, and the hollow tube 2 made of stainless steel material can play and strengthen integrally-built intensity, guarantees working life.
