Description

Technical Field

[0001] This utility model relates to an injection mold for a generator panel cover. Background Technology

[0002] In addition to their protective and decorative functions, generator panel covers also help reduce the noise generated during generator operation. To facilitate production, they are mostly made of plastic. The manufacturing process of plastic generator panel covers depends on the matching injection molds and corresponding injection molding machines.

[0003] Because the generator panel cover has multiple cavities, these cavities require the cooperation of a moving module and a fixed module in the injection mold to be formed. In the existing injection mold, the moving module and the fixed module are mainly responsible for the positioning and opening and closing of the mold. The moving module and the fixed module must also be equipped with moving mold cores and fixed mold cores for forming, respectively. The processing of the moving mold cores and the fixed mold cores must be carried out separately, and then they are assembled into the moving module and the fixed module respectively. Therefore, the processing and manufacturing process of the mold is relatively complicated, time-consuming and labor-intensive, and needs further improvement. Utility Model Content

[0028] A third forming cavity 244 is provided on the bottom surface of the first forming cavity 243, which cooperates with the rear side of the base block 131.

[0029] The bottom surface of the second molding cavity 242 is provided with a fourth molding cavity 246. Correspondingly, the moving module 1 also includes two molding core blocks 14 fixed at the front and rear respectively. The front molding core block 14 is embedded and fixed in the moving module 11, and the rear molding core block 14 is located at the rear outside of the moving module 11 and cooperates with the fourth molding cavity 246.

[0030] A first step block 1311 is formed on the rear side of the base block 131 in the direction of the shaping module 21, which cooperates with the third shaping cavity 244. A fifth shaping cavity 247 is formed on the bottom surface of the third shaping cavity 244. Correspondingly, a second step block 1312 is formed on the end face of the first step block 1311 in the direction of the shaping module 21, which cooperates with the fifth shaping cavity 247. The ends of the first insert block 132, the second insert block 133 and the third insert block 134 are all flush with the end face of the second step block 1312.

[0031] The second step block 1312 also has a first circular countersunk hole 1313 on its end face, and a protrusion 1314 is formed on the end face of the second step block 1312 toward the shaping module 21. The bottom surface of the fifth forming cavity 247 has a second circular countersunk hole 245 that cooperates with the protrusion 1314.

[0032] The end of the first insert 132 is provided with a plurality of first rib grooves 1321 arranged from top to bottom, the end of the second insert 133 is provided with a plurality of second rib grooves 1331 arranged from top to bottom, and the end of the third insert 134 is provided with a plurality of third rib grooves 1341 arranged from top to bottom.

[0033] On the inner walls of the left and right sides of the main cavity 112, there are mutually symmetrically distributed limiting notches 115. Correspondingly, on the outer walls of the left and right sides of the main protrusion 241 and the front outer wall of the molding core 24, there are mutually symmetrically arranged limiting side blocks 248. The two limiting side blocks 248 cooperate with the two limiting notches 115 respectively.

[0034] Each limiting cavity 115 has a limiting core block 116 formed between its inner wall and bottom surface. Correspondingly, each limiting side block 248 has a first limiting groove 249 on the side facing the moving module 11. Each first limiting groove 249 cooperates with a corresponding limiting core block 116.

[0035] Each limiting core block 116 is also provided with a second limiting groove 117 on the side facing the forming mold core 24. Correspondingly, a locking block 2410 is formed on the bottom surface of each first limiting groove 249 in the direction of the moving module 11. Each locking block 2410 cooperates with a corresponding second limiting groove 117.

[0036] Working principle:

[0037] The feed block 12 in the moving module 1 is installed on the action mechanism of the injection molding machine, and the base block 22 in the base module 2 is installed on the body of the injection molding machine. The action mechanism is operated to drive the feed block 12 to move backward, thereby driving the moving module 11 to move synchronously until the rear outer wall of the moving module 11 and the front outer wall of the shaping module 21 are joined together (existing technology).

[0038] During the above process, the inner forming component 13 and each forming core block 14 will move synchronously with the moving module 11. When the moving module 11 and the shaping module 21 are assembled together, the main body protrusion 241 on the forming core 24 extends into the main body cavity 112 on the moving module 11, thereby causing the first inner core protrusion 114 and the second inner core protrusion 113 to extend into the first forming cavity 243 and the second forming cavity 242 respectively.

[0039] The first step block 1311 on the base block 131 of the inner molding assembly 13 extends into the third molding cavity 244, the second step block 1312 on the base block 131 extends into the fifth molding cavity 247, the ends of the first insert block 132, the second insert block 133 and the third insert block 134 are all attached to the end face of the second step block 1312; the protrusion 1314 on the base block 131 extends into the second circular countersunk hole 245; and a molding core block 14 at the rear extends into the fourth molding cavity 246.

[0040] Subsequently, the molten material enters the space between the main body protrusion 241 and the main body cavity 112 through the gate and runner provided in the feed block 12, and after cooling, it forms the generator panel cover (existing technology); the first step block 1311 and the second step block 1312 will form a recessed cavity on the front side of the generator panel cover, and each first rib groove 1321 on the first insert block 132, each second rib groove 1331 on the second insert block 133, and each third rib groove 1341 on the third insert block 134 will form a raised rib on the bottom surface of the recessed cavity.

[0041] Then, the feeding block 12 is driven forward by the action mechanism to move the moving module 11 away from the shaping module 21. Similarly, the main body protrusion 241 is driven out of the main body cavity 112. Finally, the generator panel cover is pushed forward by the ejection mechanism 23 (existing technology).

[0042] The movable module 11 of this utility model can cooperate with the shaping module 21 to perform positioning and opening / closing functions, and can also cooperate with the forming mold core 24 to perform forming functions. Therefore, it is not necessary to install a moving mold core for forming inside the movable module 11, thus saving the processing and installation steps of the moving mold core, thereby effectively simplifying the mold processing and manufacturing process and achieving the effect of saving time and effort.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it; although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or make equivalent substitutions for some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
