Abstract
The utility model discloses an upper core box mechanism of a cold core machine. The upper core box mechanism of the cold core machine comprises a synchronous frame and guide rods. Flanges are welded at the bottoms of the guide rods. A plurality of first threaded holes are evenly arranged in docking planes of the flanges. Second threaded holes, corresponding to the first threaded holes, are arranged in the synchronous frame and connected with the first threaded holes through bolts. As the round flanges are welded at the bottoms of the guide rods, contact area between each guide rod and the synchronous frame is increased. And the number of bolts which connect the guide rods and the synchronous frame is increased from one to plurality so that bonding force between the guide rods and the synchronous frame is increased. Thus, after an upper mold is driven by the upper core box mechanism for a long time, the guide rods are still tightly connected with the synchronous frame so as to avoid misplacing in mold combining and even damaging to molds due to unequal height of two sides of the upper mold when the upper mold moves up and down. Thus, the upper core box mechanism of the cold core machine can greatly prolong service life of the molds.
Description
Technical field
The utility model relates to a kind of cold core machine, specifically a kind of upper core box mechanism of cold core machine.
Background technology
The cold core machine is a kind of plant equipment for the manufacture of core.The cold core owner will comprise workbench, mould, and the upper core box mechanism that is connected with the patrix of mould; Upper core box mechanism mainly comprises synchronous frame and is installed in four guide rods on the synchronous frame; Guide rod is connected with synchronous frame by a screw respectively, and upper core box mechanism can move up and down under two air cylinder driven in the left and right sides.
When the cold core machine carries out core when producing, patrix is with the rise and fall of upper core box mechanism, to be combined with counterdie and to separate.Upper core box mechanism cooperates four guide rods to lead up and down by two air cylinder driven in the left and right sides, the synchronism of both sides when guaranteeing to rise and descend.Yet, owing to guide rod and synchronous frame are only fixed by a screw, and because the guide rod top need to hang heavier patrix, so the force rate that this screw is subject to is larger.Behind cold core machine operation certain hour, often being used for fixing guide rod becomes flexible with the synchronously screw appearance of frame, so that patrix rise with the decline process in the not identical situation of height of its right and left, and then cause patrix with counterdie is combined the time, to occur misplacing, even cause mold damage.
The utility model content
For solving the problems of the technologies described above, the utility model proposes a kind of upper core box mechanism of cold core machine, it can prolong the mold use life-span greatly.
For achieving the above object, the technical solution of the utility model is as follows:
A kind of upper core box mechanism of cold core machine comprises synchronous frame and guide rod, is welded with flange on the bottom surface of guide rod; Be evenly distributed with several screwed holes one on the flange interface, synchronously frame is provided with the screwed hole two corresponding with screwed hole one, and screwed hole one and screwed hole two are connected by screw.
Preferably, be evenly distributed with six screwed holes one on the flange interface.
Preferably, flange is rounded.
By technique scheme, the upper core box mechanism of a kind of cold core machine provided by the utility model because the guide rod bottom welding has circular flange, thereby has increased each guide rod and the synchronous contact area of frame greatly; And since connect guide rod and the synchronous quantity of the screw of frame be increased to by one several, thereby increased adhesion between guide rod and the synchronous frame; Therefore when upper core box mechanism band patrix behind long-play, guide rod still closely is connected with synchronous frame, when having avoided patrix to move up and down because of the inconsistent mismatch that causes of its right and left height, even the situation of mold damage, therefore, the upper core box mechanism of this cold core machine can prolong the mold use life-span greatly.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, the below will do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art, apparently, accompanying drawing in the following describes only is embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the structural representation of the upper core box mechanism of the disclosed a kind of cold core machine of the utility model embodiment;
Fig. 2 is the enlarged drawing of A part among Fig. 1.
The specific embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that obtains under the creative work prerequisite, all belong to the scope of the utility model protection.
The utility model provides a kind of upper core box mechanism of cold core machine, and with reference to figure 1 and Fig. 2, it comprises synchronous frame 1 and guide rod 2, is welded with circular flange 21 on the bottom surface of guide rod 2; Be evenly distributed with six screwed holes one on flange 21 interfaces, synchronously frame 1 is provided with and the equal corresponding screwed hole two in number, position and the aperture of screwed hole one, and screw 4 passes screwed hole one and screwed hole two, so that guide rod 2 is fixed on the synchronous frame 1.
Can find out that by technique scheme the upper core box mechanism of a kind of cold core machine provided by the utility model because guide rod 2 bottom weldings have circular flange 21, thereby has increased each guide rod 2 and the synchronous contact area of frame 1 greatly; And since connect guide rod 2 and the synchronous quantity of the screw 4 of frame 1 be increased to by one several, thereby increased adhesion between guide rod 2 and the synchronous frame 1; Therefore under driving at hydraulic cylinder 3, upper core box mechanism's band patrix (not marking among the figure) is after long-time production run, guide rod 2 still closely is connected with synchronous frame 1, when having avoided patrix to move up and down because of the inconsistent mismatch that causes of its right and left height, even the situation of mold damage, therefore, the upper core box mechanism of this cold core machine can prolong the mold use life-span greatly.
To the above-mentioned explanation of the disclosed embodiments, make this area professional and technical personnel can realize or use the utility model.Multiple modification to these embodiment will be apparent concerning those skilled in the art, and General Principle as defined herein can be in the situation that do not break away from spirit or scope of the present utility model, in other embodiments realization.Therefore, the utility model will can not be restricted to these embodiment shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
