Description

Description of the Related Art [0002] A finishing device with an auto-positioning jig

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an injection molding apparatus provided with an automatic alignment jig, and more particularly, to an injection molding apparatus having an automatic alignment jig for removing the gate of an injection molding.

Generally, due to the nature of injection molding, the gate residue is unnecessarily formed in the injection molding, and since the gate residue protrudes from the surface of the injection molding as known in the art, it becomes a hindrance factor when assembled with other injection molding, . As a result, the gate residue of the injection product is removed through the mover. The mover includes a base on which a plurality of bolt holes are formed on the left and right sides of the base, a lower jig which is bolted to the base and has a cutting hole in which the injection residue is received and the gate residue is cutably positioned, And an upper jig mounted on the support member so as to be movable up and down and having a cutter. At this time, there are two types of mastifiers: a manual mast assembly in which the support member is fixed to the base and an automatic mast assembly in which the support member is moved forward and backward in the base.

On the other hand, upper and lower paper sheets of different sizes and shapes are provided on the support member and the base, respectively, according to the size, shape, At this time, when the upper and lower jigs are installed in the mover, the cutter of the upper jig must be vertically aligned with the cutting hole of the lower jig. Accordingly, after the upper jig is mounted on the support member and the lower jig is bolted to any of the bolt holes of the plurality of bolts in the base, the upper jig is lowered to determine whether the cutting holes of the upper jig and the lower jig are vertically aligned Location alignment operation to check is required. If the position is not aligned, the lower jig should be bolted to the bolt hole at another position and the upper jig should be lowered to check whether the jig is aligned.

However, depending on the quantity of product requiring finishing work, etc., the automatic and manual finishing apparatuses are selectively used in consideration of economical efficiency. When the upper and lower finishing apparatuses used in the manual finishing apparatus are to be transferred to the automatic finishing apparatus, There is a problem that you have to re-arrange the position. In addition, there is a problem in that, when using a plurality of manual mapping devices or automatic mapping devices, it is necessary to perform the alignment operation as described above when installing the top and bottom maps for each mapping device. In this way, in the related art, since the above-mentioned positioning operation must be performed every time the upper and lower paper sheets are installed in all the mapping devices, the productivity is deteriorated due to the cumbersome and time-consuming downtime.
