Specific embodiment
Embodiments of the present invention are illustrated by particular specific embodiment below, those skilled in the art can be by this explanation Content disclosed by book understands other advantages of the invention and effect easily.
Refer to Fig. 1 to Fig. 6.It should be clear that structure, ratio, size depicted in this specification institute accompanying drawings etc., is only used to Coordinate the content disclosed in specification, so that those skilled in the art understands and reads, being not limited to the present invention can be real The qualifications applied, therefore do not have technical essential meaning, the tune of the modification of any structure, the change of proportionate relationship or size It is whole, in the case where effect that can be generated of the invention and the purpose to be reached is not influenceed, all should still fall in disclosed skill In the range of art content to be covered.Meanwhile, in this specification it is cited as " on ", D score, "left", "right", " centre " and The term of " one " etc., is merely convenient to understanding for narration, and is not used to limit enforceable scope of the invention, its relativeness It is altered or modified, under without essence change technology contents, when being also considered as enforceable category of the invention.
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 This, those of ordinary skill in the art is complete with institute under technological thought without departing from disclosed spirit such as Into all equivalent modifications or change, should be covered by claim of the invention.
