The present invention provides a kind of cold-box core blower, including core shooting mechanism and core box installing mechanism, core box installing mechanism
Including upper core box installing mechanism and lower core box installing mechanism, upper core box installing mechanism is used to position upper core box and orders about upper core box
Rise or fall, as shown in Figure 1, Figure 2 and Figure 3, upper core box installing mechanism includes that one be vertically arranged drives oil cylinder 6 and drives
The connected transmission mechanism of dynamic oil cylinder 6, and four first guide posts 3 for being connected with transmission mechanism and being vertically arranged, every first
The bottom of guide post 3 is connected with the core box mounting rod 5 being fixedly linked with upper core box, drives oil cylinder 6 to drive four by transmission mechanism
The first guide post of root 3 is lifted simultaneously, completes the stabilization lifting of upper core box.The present invention drives oil cylinder to lift four simultaneously using one
First guide post, four first guide posts only need Corner Strapped respectively with upper core box, can so realize the stabilization of upper core box
Lifting, it is to avoid the crooked phenomenon of lifting occur.
For ease of realizing synchronization lifting, above-mentioned transmission mechanism includes the rotary shaft 1 of horizontally set, the two ends difference of rotary shaft
It is rotatably provided on two support columns 4, and three cantilevers being fixedly linked with rotary shaft 1, as shown in Fig. 2 and Fig. 3, and wherein
Two cantilevers (i.e. the first cantilever 81) are respectively articulated with a link 2, and two above-mentioned first guide posts are fixed with link 2
3, the link 2 of the present embodiment is constituted by being fixedly connected a montant in the middle of a cross bar, and two first guide posts 3 are symmetrical fixed
At cross bar two ends, a cantilever (i.e. the second cantilever 82) is connected with oil cylinder 6 is driven in addition.As shown in Figure 2, dotted line is in figure
Drive the flexible evolution for producing the second cantilever 82, the first cantilever 81 of oil cylinder 6.Because three cantilevers are solid with rotary shaft 1
It is fixed to be connected, when the second cantilever 82 rotates rotary shaft 1 under the jacking for driving oil cylinder 6, two the first cantilevers 81 are caused also with rotation
Rotating shaft 1 rotates, i.e. the other end lifting of the first cantilever 81 above carries the first guide post 3, on four Simultaneous Stabilizations of first guide post 3
Carry, be also achieved that the stabilization rising of upper core box, similarly, four Simultaneous Stabilizations of first guide post 3 decline, and are also achieved that core
The stabilization decline of box, thoroughly solves the unstable phenomenon crooked with lifting of upper core box lifting.It is of the invention to be using driving oil cylinder
Hydraulic cylinder is used as power source, and upper plunger tip power is big, and lifting force is big, adapts to the production of large complicated core.
Above-mentioned transmission mechanism can also be other structures, only need realize under a drive for driving oil cylinder by four pieces the
One guide post is lifted simultaneously, is not described in detail here.
As shown in Fig. 4, Fig. 5 and Fig. 6, lower core box installing mechanism includes carrying the workbench 11 of lower core box, and drives work
The elevating mechanism for making the lifting of platform 11 and the horicontal motion mechanism for driving workbench horizontal movement, elevating mechanism set workbench including top
The hoist cylinder 9 of lifting, and the crane that support works platform 11 is lifted, crane include the carriage of support works platform 11
12, and four second guide posts 10 at carriage corner are separately positioned on, every second guide post 10 is located in a fixation
In the fairlead 15 of setting, the fairlead in the present embodiment can be fixed with the frame of whole cold-box core blower, it is also possible to branch
The base for supportting whole lower core box installing mechanism is fixed.To realize the stabilization lifting of lower core box, the present embodiment is used workbench 11
On crane, there is the second guide post 10 on crane, it is ensured that stabilization lifting.Crane and hoist cylinder 9 independently set
Put, be easy to the maintenance of hoist cylinder.The stress and guiding accuracy of four second guide posts are high, will not be crooked during worktable lifting,
It is oriented to resistance to reduce, mold clamping force increases, coremaking precision is improved.
Occur horizontal sliding in fairlead to avoid the second guide post, and reduce by the second guide post and be oriented to inner room
Abrasion, as shown in Figure 5, the top of above-mentioned fairlead 15 is provided with the wear ring 14 for being located on the second guide post 10, and
Card sets the gland 13 of wear ring 14.The setting of wear ring 14 makes the lifting of the second guide post more stablize.
In sum, cold-box core blower of the invention, which ensure that the stabilization lifting of upper core box and lower core box, improves
Coremaking quality.So, the present invention effectively overcomes various shortcoming of the prior art and has high industrial utilization.
The above-described embodiments merely illustrate the principles and effects of the present invention, not for the limitation present invention.It is any ripe
The personage for knowing this technology all can carry out modifications and changes under without prejudice to spirit and scope of the invention to above-described embodiment.Cause
