The above technical purpose of the present invention is mainly solved by the following technical solutions: a door lock hinge section bar forming die comprises an upper die and a lower die, wherein a through hole is formed in the upper die, a plurality of shunting bridges extending from the side wall of the through hole to the axis of the through hole are arranged in the through hole, a welding chamber located on the inner end face of the lower die is arranged between the upper die and the lower die, a forming groove is formed in the lower die corresponding to the middle of the welding chamber, forming through holes are formed in the end portions of the forming grooves, and a forming column extending to the middle of the forming through hole is arranged at the bottom of the joint of each shunting bridge; above-mentioned shaping through-hole can cooperate with the shaping post, form the die cavity of shaping ring structure, the setting of above-mentioned through-hole, make the raw materials can follow the reposition of redundant personnel entering of through-hole department through the reposition of redundant personnel bridge and weld in the room, and after the indoor slow stream of welding, the deceleration gets into shaping through-hole and shaping inslot, thereby make the packing of raw materials more abundant even, avoid the raw materials velocity of flow too fast and lead to unable abundant packing, thereby structural strength when having guaranteed the shaping, quality problems such as fracture when avoiding taking place to extrude.
Preferably, a choke bridge surrounding the forming groove is arranged at the edge of the inner end of the forming groove; above-mentioned choked flow bridge's setting can block the raw materials that get into the seam room, slows down the flow velocity of raw materials for the raw materials deceleration gets into the shaping inslot, and in the raw materials got into the shaping through-hole faster for the shaping groove, makes the raw materials shaping of shaping through-hole department faster, fills more fully, improves shaping efficiency and quality.
Preferably, an inclined plane is arranged on the outer side of the choke bridge; the setting on above-mentioned inclined plane for the choked flow bridge guarantees that the entering into the shaping inslot that the raw materials can be smooth and easy when the choked flow to the raw materials, avoids partial raw materials to be obstructed and can't flow in dead angle department, leads to the shaping defect, and avoids causing the material waste.
Preferably, a first diversion hole located above the welding chamber is formed between every two diversion bridges; above-mentioned first reposition of redundant personnel hole's setting for the raw materials can be shunted and get into the seam indoor, increases the mobility of raw materials, makes the more even abundant of filling of raw materials.
Preferably, the height of the shunt bridge is lower than that of the opening on the top surface of the through hole; the height of the shunting bridge is lower than the height of the opening of the top surface of the through hole, so that the primary shunting effect on raw materials can be increased, the flowability of the raw materials is improved, and the raw materials can enter the through hole more efficiently.
Preferably, the bottom of the shunt bridge is gradually thinned downwards; the bottom of above-mentioned reposition of redundant personnel bridge is the taper down for after the raw materials reposition of redundant personnel, increase the space of through-hole bottom, increase the mobility of raw materials, and can be faster converge, improve shaping efficiency.
Preferably, one side of the upper die corresponding to the through hole is provided with at least one second shunting hole positioned above the welding chamber; above-mentioned second reposition of redundant personnel hole's setting, multiplicable reposition of redundant personnel effect to the raw materials for the raw materials is in many places reposition of redundant personnel entering welding chamber at the same time, improves the flow efficiency that the raw materials got into welding chamber.
Preferably, an outward expansion cavity communicated with the welding chamber is arranged at the edge of the tail end of the through hole; the arrangement of the outward-expanding cavity can reduce the limitation on raw materials, so that the raw materials can enter the welding chamber more quickly and reach the position to be filled at each position more quickly, and the filling efficiency of the raw materials is improved.
Therefore, the utility model has the characteristics of can be fully even fill shaping die cavity improves shaping efficiency and shaping quality, avoids raw materials uneven distribution to take place characteristics such as fracture even.
