Detailed Description

The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

The controller for the mold comprises a mold, wherein the mold comprises a front mold frame 4, a rear mold frame 5 and a mold frame base 6, an upper parting surface 9 is arranged between the front mold frame 4 and the rear mold frame 5, a lower parting surface 10 is arranged between the rear mold frame 5 and the mold frame base 6, the controller consisting of a movable assembly and a control assembly is arranged on two sides of the mold, and the movable assembly and the control assembly are matched with each other.

The movable assembly comprises a movable block 3 arranged at a groove on the rear mould frame 5, and the movable block 3 pushes part of the movable block 3 out of the surface of the rear mould frame 5 under the action of the elastic assembly; the elastic component comprises a limiting screw 8 for installing the movable block 3 at the groove on the rear die carrier 5, a spring 7 is arranged on the limiting screw 8, the natural state of the spring 7 can eject part of the movable block 3 out of the surface of the rear die carrier 5, the limiting screw 8 limits the movable block 3, and the telescopic state of the spring 7 can change the position of the movable block 3 at the groove on the rear die carrier 5.

Above-mentioned movable block 3 is last to be equipped with a recess, is equipped with the through-hole that a department runs through movable block 3 on the recess, and stop screw 8 passes the through-hole and is connected with the screw hole of the recess department on the back die carrier 5, and under the effect of above-mentioned spring 7, movable block 3 can be on stop screw 8 horizontal migration, and the purpose of setting up of recess is to avoid partial stop screw 8 to expose on the 5 surfaces of back die carrier, and leads to stopping the unable die sinking operation that carries on to control assembly.

Control assembly includes fixed block 1 and briquetting 2, and 1 one side fixed mounting of fixed block is at die carrier base 6, and the opposite side is equipped with the spacing groove, and is at the compound die state the spacing groove with the cooperation of mutual contact of movable block 3, therefore spacing groove and movable block 3 mutually support, the unable purpose of opening of die joint under the realization, the need of opening of die joint 10 will realize down through pushing in movable block 3, make spacing groove and movable block 3's completion disengaging process, just can open die joint 10 down.

2 one side fixed mounting of briquetting is die carrier 4 in the front, and the opposite side is equipped with the bellying, and the die sinking process is because spacing groove and movable block 3 mutually support and make down die joint 10 can't open, goes up the die joint 9 and opens the in-process, and 2 whole also begin to rise of briquetting, and the bellying acts on the movable block 3 ejecting in 5 surperficial of die carrier after last die joint 9 is opened completely just, the bellying with movable block 3 press make movable block 3 with spacing groove alternate segregation, the opening of die joint 10 down carries out again.

The part of the movable block 3, which is ejected out of the surface of the rear die carrier 5, is locally of an inclined surface structure, the inclined surface structure of the movable block 3 is inclined upwards, and the bulge can slide to the top of the inclined surface from the bottom of the inclined surface of the movable block 3 when the die is opened, so that the pushing-in process of the movable block 3 is completed.

Briquetting 2 adopts "U" type structure, and the bellying is all installed to two edges of "U" type briquetting 2, and two bellyings are used in the movable block 3, can be with the balanced pushing of movable block 3, avoid single bellying to appear the condition of high on one side low pushing movable block 3.

The utility model discloses work flow: in the die sinking process, firstly, a limiting groove on a fixed block 1 is in contact fit with a movable block 3, a pressing block 2 moves towards the movable block 3 along with the opening of an upper parting surface 9, the process that the upper parting surface 9 is opened and a lower parting surface 10 is closed is completed, then, after the upper parting surface 9 is completely opened, the protruding part on the pressing block 2 finishes pressing the movable block 3, so that the movable block 3 is separated from the limiting groove on the fixed block 1, at the moment, the upper parting surface 9 is completely opened and the lower parting surface 10 is in a pre-opening state, and finally, under the action of external force die sinking, the lower parting surface 9 is completely opened; thereby realizing the process that the upper parting surface 10 opens the lower parting surface 9 first and then opens.

The preferred embodiments and examples of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the embodiments and examples, and various changes can be made without departing from the concept of the present invention within the knowledge of those skilled in the art.
