As preferably, the loading pipe that described sizing vat comprises annular base and is coaxial docking in annular base external port, the inner side end of annular base is coaxial docking with corresponding inner flange.Sizing vat overall weight is light, and structure is simple.
As more preferably, the median pore diameter of described annular base and the equal diameters of ring port flange die cavity.When the equal diameters of sizing vat internal diameter and ring port flange die cavity, make lining consistent at the PFA layer flange of metal threeway port, namely guarantee that the PFA lining of each port is consistent, improve the reliability of product.
As preferably, the outward flange end face corresponding with described inner flange is coaxially provided with annular spacing groove, and core rod interworking extends in annular spacing groove.Annular spacing groove defines the position of core rod in metal threeway, ensure that the axiality of core rod and metal threeway, makes the interior PFA liner layer thickness uniformity of metal threeway.
As preferably, described core rod comprises vertical tube and vertical top and is connected on transverse tube on vertical tube, and in the middle part of outward flange, is provided with conducting in the balance pipe of vertical tube or transverse tube.By vertical tube and apical grafting, the transverse tube on vertical tube forms core rod, and structure is simple, is easy to split; Balance pipe on outward flange makes core rod internal and external pressure balance and is heated evenly, and improves reliability and product quality.
Sizing vat can be arranged on horizontal nose end, and as preferably, described sizing vat is located on metal threeway openend corresponding to vertical tube.When sizing vat is positioned on openend corresponding to vertical tube, is convenient to the flowing in PFA three-way pipe body shaping mold cavity when PFA material is filled, guarantees that PFA lining even density is consistent, thus maintain product quality.
As preferably, the vertical tube outside wall surface corresponding with described transverse tube port is provided with locating piece, and transverse tube interworking is slidably socketed on locating piece.Supported the medial extremity of transverse tube by locating piece, ensure that the axiality of transverse tube, guarantee that PFA liner layer thickness is consistent.
Therefore, PFA mold pressing tee joint forming die of the present utility model has following advantage: PFA is lining in being in metal threeway and forms PFA mold pressing threeway, relative to traditional welding fabrication structure, and low cost of manufacture, the bulk strength that the metal threeway of outer lining improves product is high, and Forming Quality is good.
