Specific implementation mode
Below in conjunction with the accompanying drawings and specific embodiment, the present invention is described in further details.
Attached drawing 1-5 is injection mold core cooling device of the present invention, including existing in leptosomatic core 1, setting
1 bottom of core and with the ladder blind hole 11 of 1 coaxial placement of core, be arranged 11 open end of ladder blind hole and through hole shoulder positioning
Drainage column 3, be arranged drainage 3 surface of column and with drainage column 3 be disposed vertically through-hole 31, be separately positioned on 1 surface of core and with
31 both ends of through-hole correspond to the water inlet 12 placed and water outlet 13, are separately positioned on drainage 3 inner end of column and phase vertical with through-hole 31
The inlet opening 34 of friendship and apopore 32 are arranged in ladder blind hole 11 and water inlet pipe 2 that one end is placed in inlet opening 34, setting exist
1 bottom of core and intersect the positioning runner 14 placed, one end setting with ladder blind hole 11 on drainage column 3 and the other end be placed in it is fixed
Positioning pin 4 in the sliding slot 14 of position is arranged in drainage 3 surface of column and seal groove 36 between through-hole 31 and positioning pin 4, is arranged
Dismounting threaded hole 33 in 3 outer end of drainage column is arranged in sealing ring 5 in seal groove 36；It is provided with and leads on the water inlet pipe 2
The notch 21 31 section of hole correspondence and placed towards 12 direction of water inlet；When work, as shown in figure 5, can will be more in injection mold
The water inlet 12 and water outlet 13 of a core 1 are sequentially connected in series, specially：Cold water enters the through-hole 31 of drainage column 3 from water inlet 12
It is interior, enter in water inlet pipe 2 using notch 21, then the reflux that core 1 and water inlet pipe 2 are formed is flowed by the open end of water inlet pipe 2
In portion, finally passes through apopore 32 out of, water outlet 13 flows to next core 1 water inlet 12, recycle successively.
Further, the inlet opening 34 with drainage 3 coaxial placement of column so that heat dissipation it is more uniform, and apopore 32 with into
Water hole 34 is placed in intersection, can substantially reduce the diameter of drainage column 3 so that volume is more compact.
Further, the inlet opening 34 is deeper than apopore 32, and depth is not less than the radius of inlet opening 34, is not only convenient for filling
Match, and bonding strength can be increased.
Further, fluted 35 are respectively set at the both ends of through-hole 31 on the surface of the drainage column 3；Each groove
Gasket seal 6 is both provided in 35；It can effectively prevent water inlet 12 and water outlet 13 and the junction at 31 both ends of through-hole let out
Leakage.
Further, the seal groove 36 is provided with multiple, and is uniformly placed along drainage 3 axis direction of column；Wherein seal groove
36 number highly determines by the quantity and core 1 of core 1, i.e., core 1 quantity less, height it is lower, number is fewer, instead
It, 1 quantity of core is more, height is higher, and number is more, to prevent water from pressing through height, leaks.
Further, the water inlet pipe 2 is fixed on by brazing in inlet opening 34, keeps it more firm, can effectively avoid into
Water pipe 2 is detached from inlet opening 34, and leakage etc. occurs.
Due to the application of the above technical scheme, the present invention has following advantages compared with prior art：
Injection mold core cooling device of the present invention by water inlet pipe can continuously give core side wall and top into
Row cooling, substantially reduces injection molding cycle, improves product quality, and by drain column just can realize core water inlet and
Draining so that simple in structure, small and easy to process and dismounting.
The specific application example that the above is only the present invention, is not limited in any way protection scope of the present invention.All uses
Equivalent transformation or equivalent replacement and the technical solution formed, all fall within rights protection scope of the present invention.
