Abstract
The invention relates to the field of casting, in particular to a portable method for fixing a core, consisting of a core, a lower box body, a hook, a bolt and a fixed hole; the lower box body is connected with the hook by the fixed hole; and the upper section of the hook and the bolt are used for connecting the core. After the hook passes through the fixed hole in the lower box body and the bolt at the bottom of the core is screwed down so as to fix the core. The portable method has the advantages that the original bolt connection is replaced by the hook connection, thus being time-saving and labor-saving; and the core can be fixed by screwing the connecting part with the core by using the bolt.
Description
Technical field
The present invention relates to casting field, concretely, relate to a kind of method of convenient fixedly fuse.
Background technology
The overall structure of sandbox is made of upper box and lower box, and take flange casting as example, the formed die cavity of upper box and lower box becomes the outline of foundry goods, and it is to be shaped by the apperance of flange or plank.The method of making the up and down box is called moulding.Core forms the endoporus of flange, and the method for making core is called coremaking.
On the sandbox upper box that adopts at present, inlet is arranged, there is bolt to be connected with core on lower box, during use, fixing after connecting by the up and down bolt between core and lower box, the weak point of this technology is to be connected and fixed by the up and down bolt between core and lower box to waste time and energy.
Summary of the invention
For above-mentioned technical problem, the object of the present invention is to provide a kind of method of convenient fixedly fuse, the convenient practicality of this method, with low cost.
The present invention is made of core, lower box, hook, bolt, fixing hole; Connect by fixing hole between lower box and hook, the epimere of hook is connected connecting core with bolt.
After hook passes fixing hole on lower box, the bolt tightening of core bottom is fixed core.
The invention has the advantages that: lower bolt connection is in the past changed into the hook connection, time saving and energy saving, only need to get final product with the junction of bolt tightening and core.
Description of drawings
Fig. 1 is a kind of structural representation of convenient fixedly fuse.
Reference numeral shown in Figure 1 is as follows: core 1, lower box 2, hook 3, bolt 4, fixing hole 5.
The specific embodiment
The present invention is made of core 1, lower box 2, hook 3, bolt 4, fixing hole 5; Connect by fixing hole 5 between lower box 2 and hook 3, the epimere of hook 3 is connected to connect core 1 with bolt.
After hook 3 passes fixing hole 5 on lower box 2, the bolt 4 of core 1 bottom is tightened fixed core 1.
Lower bolt connection is in the past changed into the hook connection, time saving and energy saving, only need to get final product with the junction of bolt tightening and core.
Claims (1)
1. the method for a convenient fixedly fuse, is characterized in that: be made of core, lower box, hook, bolt, fixing hole; Connect by fixing hole between lower box and hook, the epimere of hook is connected connecting core with bolt; After hook passes fixing hole on lower box, the bolt tightening of core bottom is fixed core.
