[0002] With the development of social economy, the injection molding industry is also developing rapidly. Injection molding products are the main molding equipment that uses injection molding machines to make plastic products of various shapes from thermoplastics or thermosetting materials using plastic molding molds. Injection molding is achieved through injection molding machines and molds. Injection molding machines have two main functions: (1) heating the plastic to make it melt; (2) applying high pressure to the molten plastic so that it is ejected from the mold hot nozzle and fills the mold cavity.

[0003] Inserts are frequently replaced according to product needs in daily production. The current replacement method is to first remove the mold with the insert from the injection molding machine, and then remove the insert from the mold. The installation process is just the opposite. The process steps are cumbersome, and the upper and lower molds greatly waste working time, reduce production efficiency, and also cause a waste of labor costs. Now there is an urgent need for a structure with detachable inserts for injection molding machines to solve the above problems. Utility Model Content

[0006] An insert is fixed on the lower end surface of the mounting plate, a connecting rod is installed on the lower end surface of the insert, a first limiting clamp is inserted and connected to the connecting rod and the mold base, pull-out handles are fixed on both upper and lower end surfaces of the first limiting clamp, a circular hole is opened inside the mold base, and a fastening bolt is rotatably connected inside the first limiting clamp.

[0007] Furthermore, a first rectangular hole is provided inside the mold base and the connecting rod, the inner diameter of the first rectangular hole is equal to the outer diameter of the first limiting clamping plate, and the two can be fitted and connected.

[0008] Furthermore, a fastening threaded hole is provided inside the first limiting clamping plate, the inner diameter of the fastening threaded hole is equal to the outer diameter of the fastening bolt, and the two can fit together and be rotatably connected.

[0009] Furthermore, a second rectangular hole is provided inside the mounting plate and the injection mold, the inner diameter of the second rectangular hole is equal to the outer diameter of the second limiting clamping plate, and the two can be fitted and connected.

[0010] Furthermore, a mounting hole is provided inside the injection mold, the specification of the mounting hole matches the specification of the mounting plate, and the two can fit and seal together.

[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0019] See also Figure 1-Figure 3 The utility model provides a technical solution: a structure of a detachable insert for an injection molding machine, comprising a mold base 1, a pull-out handle 2, a first limit card plate 3, a movable plate 5, a second limit card plate 6, a reset spring 7, a connecting rod 10 and a fastening bolt 12, an injection mold 4 is fitted and connected inside the mold base 1, a mounting plate 8 is fitted and connected inside the injection mold 4, a second limit card plate 6 is inserted and connected between the mounting plate 8 and the injection mold 4, movable plates 5 are fixed to the left and right end surfaces of the second limit card plate 6, and a reset spring 7 is sleeved on the outer side of the annular surface of the second limit card plate 6;

[0020] An insert 9 is fixed to the lower end surface of the mounting plate 8, and a connecting rod 10 is installed on the lower end surface of the insert 9. The connecting rod 10 and the mold base 1 are inserted and connected with a first limit clamping plate 3. Pull-out handles 2 are fixed to the upper and lower end surfaces of the first limit clamping plate 3. A circular hole 11 is opened inside the mold base 1, and a fastening bolt 12 is rotatably connected inside the first limit clamping plate 3. This design can directly remove the insert 9 from the mold base 1 without the need for upper and lower molds, thereby saving working time, improving production efficiency, and reducing labor costs.

[0021] As the first embodiment of the utility model: the inner diameter of the circular hole 11 is equal to the outer diameter of the fastening bolt 12, and the two can be fitted and slidably connected. The mold base 1 and the connecting rod 10 are both provided with a first rectangular hole. The inner diameter of the first rectangular hole is equal to the outer diameter of the first limiting card plate 3, and the two can be fitted and connected. This design enables the staff to pull out the first limiting card plate 3, so that the limiting effect of the first limiting card plate 3 on the connecting rod 10 is lost, thereby facilitating the staff to remove the insert 9. The first limiting card plate 3 is provided with a fastening threaded hole. The inner diameter of the fastening threaded hole is equal to the outer diameter of the fastening bolt 12, and the two can be fitted and rotatably connected. This design enables the first limiting card plate 3 to be fixed inside the mold base 1 through the fitting and rotatable connection between the fastening bolt 12 and the fastening threaded hole;

[0022] A second rectangular hole is provided inside the mounting plate 8 and the injection mold 4. The inner diameter of the second rectangular hole is equal to the outer diameter of the second limiting card plate 6, and the two can be fit and connected. A mounting hole is provided inside the injection mold 4. The specifications of the mounting hole match the specifications of the mounting plate 8, and the two can be fit and sealed connected. This design enables the mounting plate 8 to be limited and installed inside the injection mold 4 through the fit connection between the second limiting card plate 6 and the second rectangular hole.

[0023] As the second embodiment of the utility model: when the staff needs to remove the insert 9, first rotate the fastening bolt 12 out of the circular hole 11, so that the limiting effect of the first limiting card plate 3 is lost, and the first limiting card plate 3 is pulled out at this time, so that the first limiting card plate 3 loses the limiting effect on the connecting rod 10, and the movable plate 5 is pulled at this time, so that the movable plate 5 can drive the second limiting card plate 6 to move, so that the second limiting card plate 6 leaves the second rectangular hole inside the mounting plate 8. At this time, the staff can take out the mounting plate 8, so that the four groups of inserts 9 are pulled out of the injection mold 4, and no upper and lower molds are required, which saves working time, improves production efficiency, and reduces the use of labor costs.
