Description

Technical Field

[0001] This utility model relates to the field of mold technology, and in particular to a quick-change mold. Background Technology

[0002] Molds are various shapes and tools used in industrial production to obtain desired products through methods such as injection molding, blow molding, extrusion, die casting, forging, smelting, and stamping. In short, a mold is a tool used to shape objects; this tool is composed of various parts, and different molds are composed of different parts. It mainly achieves the shaping of objects by changing the physical state of the material being molded. It is often referred to as the "mother of industry."

[0003] We have two workpieces that are identical except for the presence or absence of holes. Currently, we are making separate molds for each of these two workpieces, which results in high production costs. Utility Model Content

[0006] The upper mold includes an upper template, a pressure plate, an upper module, a pad, and an upper mounting plate. The pressure plate is movably connected to the upper template in the vertical direction and has a through groove. The upper module is fixedly connected to the upper template, with the end of the upper module away from the upper template extending through and out of the pressure plate. The upper template has a switching groove. The pad is fixedly connected to the upper template and is located between the upper template and the pressure plate. The pad has an insert groove, and the insert groove, the switching groove, and the through groove are interconnected. The upper mounting plate is fixedly connected to the pad and is located between the pad and the pressure plate.

[0007] The lower mold is provided in a corresponding manner to the upper mold;

[0043] Please see Figures 1 to 3 The lower mold 20 includes a lower template 21, a lower mounting plate 22, a lower pressure plate 23, a lower module 24, and a punch seat 25. The lower mounting plate 22 is fixedly connected to the lower template 21, the lower pressure plate 23 is fixedly connected to the lower mounting plate 22, and the lower module 24 is fixedly connected to the lower mounting plate 22. The lower pressure plate 23 is provided with a mounting groove 231, and the punch seat 25 is fitted into the mounting groove 231, abutting against the lower mounting plate 22. The punch seat 25 is axially provided with a punch 251 adapted to the punch rod 50. The lower mounting plate 22 and the lower template 21 are provided with a waste material recovery hole 26 communicating with the punch 251. In this way, waste material can be quickly discharged from the mold through the waste material recovery hole 26, effectively improving the working stability of the quick mold switching 100.

[0044] Please see Figures 1 to 3 The switching rod 30 is retractably disposed within the switching groove 111. The lower end of the switching rod 30 is provided with a second pushing inclined surface 31. The switching block 40 is disposed in the recessed groove 141. The upper end of the switching block 40 is provided with a first pushing inclined surface 41. With the cooperation of the first pushing inclined surface 41 and the second pushing inclined surface 31, the switching rod 30 can drive one end of the punching rod 50 to be fixedly connected to the switching block 40. The other end of the punching rod 50 passes through the through groove 161 and the through groove 121 and extends out of the pressure plate 12. One end of the elastic member 60 abuts against the switching block 40, and the other end of the elastic member 60 abuts against the bottom of the fixed groove. There are two elastic members 60, which are disposed on both sides of the punching rod 50.

[0045] Please see Figure 1 The quick-change mold 100 also includes a limiting component 70, which includes an upper limiting post 71 and a lower limiting post 72. The upper limiting post 71 and the lower limiting post 72 are arranged opposite to each other.

The guide sleeve 81 is fixedly connected to the upper template 11, and the upper template 11 is provided with a guide hole. One end of the guide rod 82 is fixedly connected to the lower template 21, and the other end of the guide rod 82 passes through the guide sleeve 81 and extends into the guide hole.

[0047] The working principle of the quick-change mold 100 in this embodiment is as follows: When making a workpiece that requires punching 251, the operator inserts the switching rod 30 into the switching groove 111. Under the cooperation of the first pushing inclined surface 41 and the second pushing inclined surface 31, the switching block 40 is driven to move downward. The end of the punching rod 50 away from the switching block 40 passes through the through groove 161 and the through groove 121 and extends out of the upper mold 10. Thus, the punching rod 50 can cooperate with the punching seat 25 to punch 251. When making a workpiece that does not require punching 251, the operator pulls the switching rod 30 out of the switching groove 111. The switching block 40 moves upward under the action of the elastic element 60, and the punching rod 50 extends into the through groove 121. In this way, the mold can be switched. When making two workpieces that are completely identical except for the presence or absence of holes, it is not necessary to make two sets of molds, but only one quick-change mold 100 is needed, thereby reducing production costs.

[0048] The beneficial effects of this utility model are as follows: the mold switching can be realized through the cooperation of the upper mold 10, lower mold 20, switching rod 30, switching block 40, punching rod 50 and elastic element 60. Therefore, when making two workpieces that are completely identical except for the presence or absence of holes, it is not necessary to make two sets of molds, but only one quick-switching mold 100 is needed, thereby reducing production costs.

[0049] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0050] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
