Description

Fixture and method for assembling mold structure using the same

The present invention relates to a jig, and more particularly to a jig for assembling a mold structure and a method of assembling a mold structure using the jig.

At present, in the products of electronics, automobiles, motors, electrical appliances, instruments, home appliances and communications, 70%-90% of the parts require mold forming and manufacturing, and the mold has become an important equipment for industrial production.

In the conventional mold structure, the front substrate and the female mold base are provided with screw holes, and are fixed by screws, however, the above-mentioned screw holes form a large pore tolerance during processing, so the front substrate and the front substrate are When the female mold base is locked, deviations may occur due to the tolerance. Similarly, a deviation may occur between the rear substrate and the male mold base. If the front substrate is not accurately aligned with the female mold base or the rear substrate and the male mold base, when the male and female mold bases are closed, the front substrate will be due to the positioning device of the male and female mold bases themselves. The rear substrate is not parallelized. Therefore, when the mold is to be fixed on the molding machine, the screw holes of the front and rear substrates and the screw holes of the molding machine may be misaligned, resulting in a bad upper mold, if the hard lock is even Will cause a broken tooth.

At present, when assembling the mold structure, in order to reduce the above deviation, most of the operators measure the distance from the edge of the female/mold base to the edge of the front/rear substrate by visual inspection or by a vernier caliper. It is confirmed that the female/mold holder is fixed to the position on the front/rear substrate. However, the above visual method has large error, which is not conducive to accurate assembly of the mold structure; the measurement by the vernier caliper is cumbersome, and each time the mold structure is assembled, measurement is required, which is not conducive to cost saving. Therefore, it needs to be improved.

In view of the above, it is necessary to provide a jig for facilitating accurate assembly of a mold structure and a method of assembling the mold structure using the jig.

A fixture for assembling a mold structure, the mold structure comprising a substrate and a mold base, the substrate and the mold base are provided with a plurality of fixing holes, the fixing holes on the substrate and the fixing holes on the mold base In one-to-one correspondence, the fixture includes a substrate receiving slot and a die holder receiving slot communicating with the substrate receiving slot. The substrate receiving slot and the die receiving slot are respectively configured to receive the substrate and the die holder. When the die holder is received in the die holder receiving groove, the fixing hole on the substrate is opposite to the fixing hole on the die holder.

A method for assembling a mold structure, the mold structure comprising a substrate and a mold base, wherein the substrate and the mold base are provided with a plurality of fixing holes, and the fixing holes on the substrate are in one-to-one correspondence with the fixing holes on the mold base, The method includes the following steps: providing a fixture, the fixture includes a substrate receiving slot, and a die holder receiving slot communicating with the substrate receiving slot, the substrate receiving slot and the die receiving slot respectively for receiving the substrate and In the mold base, when the substrate is received in the substrate receiving groove and the die holder is received in the die holder receiving groove, the fixing hole on the substrate is fixed to the die hole; the substrate and the die holder are respectively Storing in the substrate receiving groove of the jig and in the die holder receiving groove; using a plurality of fixing elements respectively corresponding to the fixing holes on the die holder and the substrate A fixing hole is fixed to the base plate.

When the mold structure is assembled by using the above-mentioned jig, the fixing holes on the mold base are directly opposite to the fixing holes on the substrate, so that the substrate and the mold base can be accurately aligned. Further, each time the above-described mold structure is assembled, it is not necessary to repeatedly measure the distance from the side surface of the mold base to the side surface of the substrate, and the process is simple.
