Description

Technical Field

[0001] The utility model relates to the field of auxiliary tools for the production of injection molded parts, and particularly relates to an insert removal tool. Background Art

[0002] In the prior art, for an injection molded product with an embedded metal component, generally, an insert is used to bury the metal component in a mold in advance. After the workpiece is injection molded, the plastic component and the metal component are integrally formed. At this time, due to the high temperature, it is not easy to remove the insert from the metal component, and some tools are needed to complete the insert removal work. For example, a kind of insert removal jig with the publication number of CN219336701U includes a machine table, a workpiece mold base, a pulling and disassembling cylinder and a pressing mechanism. The injection molded workpiece is clamped on the workpiece mold base, the pressing mechanism presses on the top of the injection molded workpiece, and the driving shaft of the pulling and disassembling cylinder is provided with a disassembling head that is clamped and matched with the insert. The pulling and disassembling cylinder is used to drive the disassembling head to move away from the injection molded workpiece until the insert is separated from the injection molded workpiece. This disassembling head separates the insert from the injection molded workpiece by hard pulling the insert. During the hard pulling process, it is easy to deform the injection molded workpiece and affect the quality of the injection molded workpiece. Summary of the Utility Model

[0027] The fixed seat 4 can move closer to or away from the rotary disassembly assembly 5. Specifically:

[0028] On the first side of the bottom plate 3, a first sliding rail 31 is provided, and one end of the first sliding rail 31 extends towards the screwing and disassembling assembly 5. A slider is connected to the bottom of the fixing seat 4, and the slider is connected to the first sliding rail 31 in a matching manner, so that the fixing seat 4 is slidably connected to the first sliding rail 31. A receiving cavity 41 for fixing the injection molded part 11 is provided in the fixing seat 4. On the side of the receiving cavity 41 facing the screwing and disassembling assembly 5, two openings 411 are provided. The two openings 411 are arranged along a direction perpendicular to the first sliding rail 31, and each opening 411 communicates with the receiving cavity 41. When the injection molded part 11 is placed in the receiving cavity 41, the insert 12 is at least partially located outside the receiving cavity 41.

[0029] On the second side of the bottom plate 3, a second sliding rail 32 is provided.

[0036] A detection block 54 is connected to the lower part of the rotary detaching head 53, and the detection block 54 protrudes downward from the flat plate portion 531.

[0037] In Figure 2 and Figure 3 , two position sensors 8 are arranged between the fixed seat 4 and the rotary detaching assembly 5. The position sensors 8 are arranged in one-to-one correspondence with the openings 411, and the position sensors 8 are arranged along the moving direction perpendicular to the fixed seat 4. The position sensors 8 are connected to the electric control box 6. The position sensors 8 can be contact sensors or proximity sensors, and the latter is preferably used in this embodiment.

[0038] When the support 52 moves along the second slide rail 32, the detection block 54 sequentially enters the detection range of the corresponding position sensor 8 and triggers the corresponding rotary drive device 51 to perform a rotary action, which is beneficial to realizing automatic operation and improving work efficiency.

[0039] Furthermore, two mounting rails 33 are arranged between the fixed seat 4 and the rotary detaching assembly 5. The mounting rails 33 are arranged parallel to the second slide rail 32.
