Description

Technical Field

[0001] The utility model relates to the technical field of molds, in particular to a positioning structure of a mold for injection molding. Background Art

[0002] The mold for injection molding is a tool for manufacturing plastic products. It plays a vital role in the injection molding process. During the plastic molding process, the plastic needs to be heated to a melted state first, and then an injection molding machine is used to inject the melted plastic into the injection mold, and then it is cooled and molded.

[0003] During the long-term use of current injection molds, the mold material may fatigue, especially in the high temperature and high pressure injection molding environment. This fatigue will cause the mold structure to deform, which will cause position deviation, so that the mold may not be tightly closed during the mold closing process, which not only easily causes damage to the injection mold, but also greatly affects the quality of plastic processing. Therefore, those skilled in the art provide a positioning structure for injection molding molds to solve the problems raised in the above background technology. Utility Model Content

[0004] In order to solve the problem that the mold may not be tightly closed during the mold closing process, which not only easily causes damage to the injection mold but also greatly affects the quality of plastic processing, the utility model provides a positioning structure for the mold for injection molding.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] The utility model embodiment discloses a positioning structure of a mold for injection molding. Figure 1-4 A positioning structure for a mold for injection molding comprises a workbench 1, a right mold 2 is arranged at the inner right end of the workbench 1, a positioning sleeve 3 is arranged at the upper end of the right mold 2, a positioning mechanism 4 is arranged inside the positioning sleeve 3, a first indicator light 5 used in conjunction with the positioning mechanism 4 is arranged at the upper front end of the right mold 2, a pushing mechanism 6 is arranged at the inner left end of the workbench 1, a left mold 7 is arranged on one side of the pushing mechanism 6, a mounting block 8 is arranged at the upper end of the left mold 7, a positioning rod 9 used in conjunction with the positioning mechanism 4 is arranged at the right end of the mounting block 8, and a controller 10 is arranged at the inner right end of the workbench 1;

[0021] The positioning mechanism 4 includes a connecting block 401, a travel switch 402 and a spring 403. The connecting block 401 is slidably arranged inside the positioning sleeve 3. The travel switch 402 and the spring 403 are both arranged on the left side of the connecting block 401. The left end of the spring 403 is connected to the inner wall of the positioning sleeve 3, and the travel switch 402 is located on the inner side of the spring 403. The travel switch 402 is electrically connected to the controller 10.

[0022] By adopting the above technical solution, when the left mold 7 moves to the right, the positioning rod 9 will be driven to move to the right, so that the first indicator light 5 will light up after the positioning rod 9 is inserted into the positioning sleeve 3, or the positioning rod 9 will be inserted into the positioning sleeve 3. The use position of the right mold 2 and the left mold 7 can be positioned and monitored.

[0023] Reference Figure 1 The pushing mechanism 6 includes an electric push rod 601 and a mounting plate 602. The electric push rod 601 is arranged at the inner left end of the workbench 1, and the mounting plate 602 is arranged at the right end of the electric push rod 601. The mounting plate 602 and the left mold 7 are connected by bolts, and the electric push rod 601 is electrically connected to the controller 10.

[0024] By adopting the above technical solution, the electric push rod 601 can drive the installation plate 602 to move, and the movement of the installation plate 602 can drive the left mold 7 to move, so that the right mold 2 and the left mold 7 can be combined to perform injection molding on the plastic.

[0025] Reference Figure 4 A pressure sensor 11 is arranged inside the positioning sleeve 3, and the pressure sensor 11 is located at the right end of the connecting block 401. A second indicator light 12 used in conjunction with the pressure sensor 11 is arranged on the front of the right mold 2. Both the pressure sensor 11 and the second indicator light 12 are electrically connected to the controller 10.

[0026] By adopting the above technical solution, when the first indicator light 5 is on, the positioning rod 9 contacts the travel switch 402 and continues to push the connecting block 401 to move and squeeze the pressure sensor 11. After the pressure value of the pressure sensor 11 reaches a predetermined value, the second indicator light 12 is on, indicating that the right mold 2 and the left mold 7 are tightly closed. If the second indicator light 12 does not light up after the first indicator light 5 is on, it indicates that the right mold 2 and the left mold 7 are not tightly closed. Therefore, the closing condition of the right mold 2 and the left mold 7 can be monitored, thereby ensuring the processing quality of the plastic.

[0027] Reference Figure 3 An injection cavity 13 is opened on the left side of the right mold 2, and an injection port 14 is opened on the front side of the right mold 2.

[0028] By adopting the above technical solution, injection molding is performed in the injection cavity 13 through the injection port 14, thereby completing the injection molding of the plastic product.

[0029] Reference Figure 1 and Figure 2 A plurality of slide grooves 15 are provided at the inner left end of the workbench 1 , and a plurality of sliders 16 are provided at the bottom end of the left mold 7 . The bottom ends of the sliders 16 penetrate into the slide grooves 15 and are slidably connected with the slide grooves 15 .

[0030] By adopting the above technical solution, when the left mold 7 moves, the slider 16 will be driven to move in the slide groove 15, so that the left mold 7 moves more stably.

[0031] Working principle: When the utility model is in use, the staff can push the left mold 7 to move to the right by operating the electric push rod 601 to drive the mounting plate 602 to move. When the left mold 7 moves to the right, it will drive the positioning rod 9 to move to the right. When the positioning rod 9 is inserted into the interior of the positioning sleeve 3 and the travel switch 402 is squeezed, the travel switch 402 is squeezed and the first indicator light 5 is lit, indicating that the use position of the right mold 2 and the left mold 7 has not shifted. When the positioning rod 9 is not inserted into the interior of the positioning sleeve 3 or the first indicator light 5 is not lit when it is inserted into the interior of the positioning sleeve 3, it indicates that the use position of the right mold 2 and the left mold 7 has been When the first indicator light 5 is on, the positioning rod 9 contacts the travel switch 402 and continues to push the connecting block 401 to move and squeeze the pressure sensor 11. When the pressure value of the pressure sensor 11 reaches a predetermined value, the second indicator light 12 is on, indicating that the right mold 2 and the left mold 7 are tightly closed. If the second indicator light 12 does not light up after the first indicator light 5 is on, it indicates that the right mold 2 and the left mold 7 are not tightly closed. Therefore, the closing condition of the right mold 2 and the left mold 7 can be positioned and monitored, thereby ensuring the processing quality of the plastic.

[0032] When the utility model is in use, the use positions of the right mold 2 and the left mold 7 can be located and monitored during the injection molding process of the plastic, so that once the right mold 2 and the left mold 7 are offset, the injection molding work can be stopped in time, which greatly improves the protection of the right mold 2 and the left mold 7 and ensures the processing quality of the plastic.
