Specific embodiment
Below in conjunction with attached drawing, specific embodiment of the present utility model is described in further detail, so that the utility model skill
Art scheme is more readily understood and grasps.
Embodiment:
Referring to shown in Fig. 2-4, the present embodiment provides a kind of high-efficiency moulds that can effectively improve pulling rate, including outer housing 1
Copper pipe 2 with being set in outer housing 1, is wherein electroplate with one layer of chrome layer 201 on the inner wall of copper pipe 2；Due in ferrostatic pressure
Under effect, it can generate frictional force when doing relative motion between 2 inner wall of pre-hardening casting billet surface and crystallizer copper pipe and subject high temperature
Heat transfer and radiation, so copper pipe 2 must have good wear-resisting property and conduct hot, cooling and good rigidity, therefore
The chrome layer 201 of one layer of 0.10 ~ 0.12mm densification is electroplate on 2 inner wall of copper pipe, to improve the wear-resisting property of copper pipe 2；
It further include wherein being formed and being supplied between 2 outer wall of water jacket 3 and copper pipe by the fixed water jacket 3 being set on copper pipe 2 of screw
The water seam 4 that cooling water passes through finds, when the clearance distance by water seam 4 is 4mm, cooling effect is most in long-term many experiments
It is obvious；Outer housing 1 is separated by upper water cavity 6 and lower water cavity 7 by partition 5 in outer housing 1, there is outlet pipe on upper water cavity 6
8, there are on lower water cavity 7 water inlet pipe 9, the rings that 3 upper end outer wall of water jacket is equipped with the coaxial arrangement of water jacket 3 and is connected to water seam 4
Shape chuck 10, wherein offering the sink 11 being coaxially disposed with annular chuck 10 on the upper surface of annular chuck 10；Sink
11 bottom offers first apopore 12 of several circumferentially array distributions；3 upper portion side wall of water jacket is close to annular chuck 10
Position on offer several second apopores 13；Annular chuck 10 is sealingly mounted at 1 upper end of outer housing by upper flange 14；Copper
The upper end wall of pipe 2 contradicts on the lower wall of upper flange 14, and 2 upper end wall of copper pipe and the resistance surface of upper flange 14 are close equipped with first
Gasket 15.
O-ring 16 is equipped on the contact surface of annular chuck and upper flange 14 and outer housing 1.The purpose of O-ring 16 is set
It is to improve leakproofness.
