Technical Field
[0001] The present application relates to the field of molds, and in particular to a rear mold of a molding mold. Background Art
[0002] A mold is a variety of molds and tools used in industrial production to obtain the desired products by methods such as injection molding, blow molding, extrusion, die-casting or forging, smelting, stamping, etc. A mold generally includes a front mold and a rear mold. A mold cavity for molding objects is formed between the front mold and the rear mold. The front mold generally refers to the ejection side of the mold, and the rear mold generally refers to the side connected to a fixed machine. The two can be separated and combined. When the two are separated, the molded object can be taken out. When they are combined, the material liquid is injected into the mold cavity for molding. The mold cavity needs to be determined according to the shape of the molded object. Due to actual needs, most of the current objects have complex structures. For example, the outer shell of a kettle. The inner wall of the outer shell of the kettle needs to be provided with a buckle for connecting to other parts of the kettle. For this buckle, most of the current molds use an insert with a spring. Before demolding, the spring structure is used to first detach the insert, and then the molded object is ejected and demolded. However, the above structure is relatively complex, and most of the outer shells of the kettle contain multiple buckles, which makes demolding cumbersome and inconvenient. Utility Model Content

The molded object is separated from the mold core 2 and the demoulding component of the core 3. After molding is completed, the movable template 1 moves away from the fixed template 4, and the core 3, the first insert 5 and the molded object move synchronously with the movable template 1, so that the guide block 6 moves downward relative to the first insert 5. Due to the inclined setting of the T-slot 7, the first insert 5 moves toward the inside of the core 3, thereby separating the first insert 5 from the molded object, and then the demoulding component ejects the molded object from the core 3 to complete the demoulding. The demoulding of the buckle is completed by the cooperation of the first insert 5 and the guide block 6. The structure is simple, volume is saved, and demoulding is convenient and quick.
[0025] like Figure 2 As shown, a fixing ring 8 is also provided in the mold core 2, and the fixing ring 8 is sleeved on the outer side of the core 3 and the first insert 5, and the upper surface of the fixing ring 8 is used to cooperate with the lower surface of the molded object. The lower surface of the first insert 5 is in contact with the mold core 2, so that the first insert 5 can slide horizontally on the mold core 2. The setting of the fixing ring 8 makes the first insert 5 always embedded in the core 3. When molding the object, the position of the first insert 5 is made more precise. The upper and lower ends of the T-shaped groove both pass through the guide block 6, so that the top of the first insert 5 can be flush with the top of the guide block 6 during molding. When the two are placed in the core 3, it is beneficial to make the structure of the core 3 simpler.

[0027] like Figure 2 and Figure 4As shown, a second insert 11 is embedded on the core 3, and a cylindrical protrusion for cooperating with the molded object is arranged on the side of the second insert 11, and the lower end of the protrusion is connected with a connecting rod 12 inclined toward the inner side of the core 3, and the connecting rod 12 passes through the core 3, the movable template 1 and the fixed template 4 and is slidably connected to the demolding movable platform 9 in the horizontal direction. When demolding, the demolding movable platform 9 moves toward the fixed template 4, and the connecting rod 12 ejects the second insert 11 along with the molded object. At the same time, since the connecting rod 12 is inclined, the second insert 11 moves toward the inner side of the core 3 during the rising process, so that the protrusion on the second insert 11 is separated from the molded object, thereby realizing demolding.
[0028] In addition, a third insert 13 is provided on the side of the mold core 2 facing the core 3, and the upper top surface and side surfaces of the third insert 13 are used to cooperate with the structure of the kettle shell.
[0029] The implementation principle of this embodiment is:
[0030] After molding is completed, the movable template 1 moves away from the fixed template 4, and the core 3, the first insert 5 and the molded object move synchronously with the movable template 1, so that the guide block 6 moves downward relative to the first insert 5. Due to the inclined setting of the T-slot 7, the first insert 5 moves toward the inner side of the core 3, thereby separating the first insert 5 from the molded object, and then the demoulding movable platform 9 moves toward the fixed template 4, thereby driving the demoulding ejector 10 to lift the object molded on the core 3, and the connecting rod 12 ejects the second insert 11 following the molded object. At the same time, since the connecting rod 12 is inclined, the second insert 11 moves toward the inner side of the core 3 during the rising process, so that the protrusion on the second insert 11 is separated from the molded object, and the demoulding of the buckle is completed through the cooperation of the first insert 5 and the guide block 6. The structure is simple, volume is saved, and demoulding is convenient and quick.
