The utility model discloses a mould isosceles structure in the technical field of forming mould, including lower die seat and lower die core plate. Lower die seat has the core plate groove, and lower die core plate is fixed in the core plate groove. Lower die seat is equipped with a plurality of isosceles columns, and a plurality of isosceles columns are arranged around the outer periphery of the core plate groove. The upper end of isosceles column has the positioning end face. In the mould isosceles structure of the utility model, lower die core plate is positioned through the core plate groove, and the height position of the positioning end face of isosceles column is controlled in accuracy to the effect of mould closing, and the difficulty of detection and processing is low, thereby reducing the machining accuracy requirement and the casting cost of lower die seat, and having important economic significance for production.

The utility model relates to valve technical field, concretely relates to a regulating valve with lining, including valve body, the first lining is arranged in the valve body, and the inner wall of valve body is provided with a plurality of dovetail groove convenient for fixing first lining, the valve rod is inserted in the bonnet, the lower place of valve rod is sleeved with the valve core, the top surface of valve core is provided with the pouring hole, the outside of valve core is provided with the ring groove, the bottom of valve core is provided with the self -tightening mechanism, the utility model discloses through dovetail groove, pouring hole and ring groove, make the lining material and valve body form reliable connection, strengthen the fixed stability of lining, prolong the service life of valve, reduce the metal material amount, reduce the foundry cost, still effectively reduced the operating force needed to control valve rod, through the self -tightening mechanism cooperation valve core common sealing valve seat, the sealing performance of remarkable promotion, shared the valve -in -medium pressure that valve rod bore, improved the pressure -bearing capacity and reliability of valve.

The utility model relates to a temperature control device for bridge cable hot casting anchor anchoring material casting, relates to the device of hot casting anchor anchoring material casting, including at least one installation dynamic heat preservation device on the anchor cup, dynamic heat preservation device includes annular sleeve, heat preservation device, temperature sensor, control system, the inner hole of annular sleeve is covered on the outer surface of anchor cup, heat preservation device, temperature sensor are installed in the closed cavity of annular sleeve respectively, the signal output end of temperature sensor is connected with the signal input end of control system, the signal output end of control system is connected with heat preservation device, the utility model discloses through heat preservation device can make the anchoring material in the anchor cup keep proper temperature, solve the problem of the insufficient compactness caused by the big void ratio of anchoring material and the uneven casting, further promote the anchoring efficiency, can also reduce the thermal stress crack in the cooling process of casting, significantly improve the anchoring material quality.
