Description

Die casting mold blocking mold, rapid mold changing system and method Technical Field The invention relates to the technical field of die casting dies, in particular to a die casting die block die, a rapid die changing system and a rapid die changing method. Background With the continuous increase of products, the die casting die breaks through the limit of the existing metal materials from size to weight, and meanwhile, the difficulty in assembly caused by the die casting die with larger tonnage enlarges the downtime of die casting production. Traditional die casting molds require an external mating mold frame to internally mount the molded core part of the product. The mold core of product belongs to the special part, and the change of product can lead to the unable continuation of external form frame that matches with it to be used, and external form frame receives impact load and violent temperature alternation influence low simultaneously in the die casting process, and its actual service condition can obtain the assurance of long ageing. However, due to the high matching of the mold outer frame and the product core, a large amount of overflow waste is generally generated in the service life of the mold outer frame along with the updating of the product of the core. Disclosure of Invention Aiming at the defects of the prior art, the invention aims to provide a die casting mould block mould, a rapid mould changing system and a method, wherein the die is divided into a general part and a special part, the modularization of the die is realized, the sharing of long-service-life parts of the die is realized, and the rapid replacement of the die casting mould is realized based on the modularized design structure of the die and the coupling of a die casting machine and a die changing platform. In order to achieve the above object, the present invention is realized by the following technical scheme: in a first aspect, embodiments of the present invention provide a die-casting mold block mold comprising: The die universal part comprises a die bottom plate, wherein one side of the die bottom plate is connected with a core mounting block and a movable die runner bottom plate, and the movable die runner bottom plate is provided with a guide groove for being matched with a die changing platform; and the special part core is connected with the core mounting block and the runner bottom plate of the movable mould, wherein the mould is matched with the mould to form a frameless mould in a mould core attaching mode. As a further implementation, the movable mould runner bottom plate positions the dedicated part core by using a circular split cone. As a further implementation mode, fluid connection plates are arranged on two sides of the die bottom plate and are matched with fluid connectors of the die casting machine.
