The locking piece 3 is used for enabling the front back plate 11 and the front die core 14 to be opened before the front die core 14 and the rear die core 25 in the die opening process, so that the slag ladle is broken before the die cavity is opened.
In use, in the closed mold state, the front cavity 14 and the rear cavity 25 form a cavity, and the slag ladle cavity 41 is communicated with the cavity through the communication channel 141. During glue injection, cold material, air and molten glue in the cavity can flow into the slag ladle cavity 41 through the communication channel 141, so that the problems of unsaturated material and incompact of die casting raw materials in the cavity are effectively relieved, and the strength, density and quality of a formed product are improved.
After cooling, a slag ladle is formed in the slag ladle cavity 41, and when the mold is opened, the front mold insert 14 and the movable mold 2 are integrated (hereinafter referred to as "integrated structure") under the action of the locking member 3, and the integrated structure is separated from the front back plate 11 (hereinafter referred to as "first distance" for separation distance), that is, the slag ladle cavity 41 is separated from the communication channel 141. By utilizing the cohesive force between the slag ladle and the wall surface of the slag ladle cavity 41 and the acting force generated in the process of separating the integral structure from the front back plate 11, the slag ladle in the slag ladle cavity 41 and the product in the communicating channel 141 are broken, thereby realizing the automatic separation of the slag ladle and the product. By arranging the mounting seat 4 and utilizing the cohesive force between the slag ladle and the wall surface of the slag ladle cavity 41 and the acting force generated in the process of separating the integral structure from the front backboard 11, the automatic slag ladle breaking function is realized, and the structure is simple and compact.
After the integral structure is separated from the front backboard 11 by a first distance, the front mold core 14 is separated from the movable mold 2, and the cavity is opened, so that the product can be removed.
In this embodiment, the fixed mold 1 further includes a front blank 13 and a front core backing plate 12, the front blank 13 is movable relative to the front back plate 11, the front core backing plate 12 is fixedly connected to the front blank 13, and the front core 14 is fixed to the front core backing plate 12.

In addition, when the front backboard 11 is separated from the integral structure, the slag ladle is more easily broken between the slag ladle and the product under the action of the pulling force and moment of the product on the slag ladle, so that the slag ladle is separated from the product.
In this embodiment, the front blank 13 is provided with a through slot, and the mounting seat 4 passes through the through slot so that the end surface of the mounting seat abuts against the front mold core 14, and further the slag ladle cavity 41 is in sealed communication with the communication channel 141. The through groove is arranged on the front blank plate 13, so that the communication between the slag ladle cavity 41 and the communication channel 141 is realized, and the overall structure of the upper die is more compact.
In this embodiment, the mounting base 4 is provided with an ejector assembly 5, and the ejector assembly 5 includes an inner ejector insert 51 and an inner ejector pin 52, where the inner ejector insert 51 is fixedly connected to the front blank 13. After the front backboard 11 is separated from the integral structure by a first distance, the front backboard 11 is further separated from the integral structure, meanwhile (namely, in the process of further separating the front backboard 11 from the integral structure), the front blank 13 is separated from the rear blank 24, the front mold core 14 and the rear mold core 25 are opened, and in the process, the inner ejector insert 51 is in abutting and pressing fit with the inner ejector pin 52 so as to drive the inner ejector pin 52 to move into the slag ladle cavity 41, so that a slag ladle is ejected, and the function of automatically ejecting the slag ladle is realized.
