Forming die in inner-core replaceable form

Abstract

The invention relates to a forming die in an inner-core replaceable form. The forming die comprises an upper die and a lower die which are mutually matched; the forming die further comprises a lower die backing plate which is fixedly arranged on the lower die and at least two fixed pull rods which can be movably arranged on the lower die backing plate; at least one inner core fielded panel is detachably arranged on each fixed pull rod; and at least one inner core for forming a product is arranged on each inner core fielded panel. According to the forming die disclosed by the invention, a movable inner core structure in a traditional die is modified into a relatively-fixed structure, so that the problem that the inner core is brought up and falls to crush a parting face of the lower die during die parting is solved, the service effect of the die is guaranteed to a maximum extent, and the service life of the die is prolonged. Meanwhile, the invention also adopts a quick-replaceable structure, so that the whole forming surface of the die can be quickly replaced, further the feeding and discharging time of products is saved, and the production efficiency of processing enterprises is greatly improved.

Description

technical field [0001] The invention relates to a forming die, in particular to a forming die capable of realizing quick replacement of the inner core of the die, and belongs to the technical field of forming processing. Background technique [0002] In the field of molding processing technology, the stamping dies or injection molds used basically include upper and lower dies that match each other, and there is a cavity for product molding between the upper die and the lower die. During the processing of some products that require precision molding, the mold used will also include several inner cores. Most of these inner cores will be placed directly on the surface of the lower mold, and the two are not fixed. In this way, there will be a problem, that is, after the mold is closed and the product is formed, when the mold is opened and the product is blanked, the inner core is likely to be taken up along with the product, and it is easy to drop. In addition, the mass of the...

Problems solved by technology

In this way, there will be a problem, that is, after the mold is closed and the product is formed, when the mold is opened for product blanking, the inner core is likely to be taken up with the product, and it is easy to fall

In addition, the quality of the inner core is relatively large, so the falling inner core can easily damage the parting surface of the lower mold of the mold, resulting in damage to the mold and shortening the service life of the mold

[0003] In addition, since the inner core in the existing mold is set relatively independently, workers need to manually operate one by one during the installation of the inner core and the operation of product blanking

There is no doubt that such a production method is extremely inefficient, which largely limits the production speed of processing enterprises and affects the production efficiency of processing enterprises.

[0004] To sum up, how to realize the relative fixation of the inner core in the mold, avoid the problem of the inner core being lifted up, falling and damaging the parting surface of the lower mold when the mold is parting, and at the same time improve the efficiency of product loading and unloading, has become a basic problem. Problems urgently needed to be solved by field technicians
