The service life of mold.
One aspect according to the present utility model, provides hollow three round tube holes bearing diagonal pipe mold, including upper mold and
Lower die, upper mold is fastened on lower die by positioning pin, and is screwed, the circumferentially distributed multiple tap holes of upper mold, in the middle part of upper mold
Equipped with rectangular dorsal pore, rectangular dorsal pore is uniformly divided into multiple through-holes, and upper mold discharge end is equipped with multiple mold cores, sets in the middle part of lower die feed end
There is die hole, mold core is vertically corresponding to be inserted into die hole, thereby, it is possible to effectively guarantee that the feed of center round tube hole and muscle fills part, accurately
Round tube hole size and position, improve the processing efficiency of aluminum profile, while enhancing the service life of mold.
Further, tap hole has eight, flare, from a side opening of the laterally closer mold core far from mold core
It is gradually increased, thereby, it is possible to effectively balance into aluminium flow velocity, mitigates mold squeeze pressure, enhance die life.
Further, the first shunt bridge is equipped between two adjacent tap holes, the first shunt bridge underbeam gradient is
25 °, thereby, it is possible to control flow rate of metal, mitigates squeeze pressure, improve weldquality.
Further, there are four through-hole tools, the second shunt bridge is equipped between two adjacent through-holes, second shunts bridge bearing
Mold core, thereby, it is possible to guarantee that round tube hole feed in center is abundant, it is ensured that mold core intensity enhances die life.
Further, there are three mold core tools, including the first mold core, the second mold core and third mold core, the first mold core are located at institute
Upper mold geometric center is stated, the second mold core and third mold core are respectively symmetrically located at the first mold core two sides, and thereby, it is possible to accurate round tube holes
The processing efficiency of aluminum profile is improved in size and position.
Further, a fabrication hole is offered on the end face of third mold core face lower die one end, thus, it is possible to mitigate mold core
Pressure.
