Description

Technical Field

[0001] This utility model relates to the field of jig technology, and in particular to an extraction jig. Background Technology

[0002] During the machining process, pins need to be embedded in the workpiece to achieve subsequent electrical connections. Currently, in injection molding, the pins are inserted into an inner mold component, which is then placed together with the pins into the corresponding position in the injection mold. During injection molding, the pins naturally embed themselves within the workpiece. After demolding, the inner mold component is manually removed to separate it from the workpiece. Currently, there is no efficient and suitable automated equipment to replace manual labor. This manual removal method is labor-intensive and difficult to adapt to the current trend of production automation. Utility Model Content

[0003] To overcome the shortcomings mentioned above, this utility model aims to provide a technical solution that can solve the above problems.

[0004] A extraction fixture includes a base, a fixture seat, and an extraction assembly. The fixture seat is disposed on the top surface of the base, and a fixture slot is formed on the top surface of the fixture seat. The extraction assembly is disposed on the top surface of the base and located on one side of the fixture seat. The extraction assembly includes a drive member and an extraction block. A positioning pin is provided on the top surface of the extraction block near its end. The beginning end of the extraction block is connected to the output end of the drive member. The drive member can drive the extraction block to move along the length direction of the base so that the end of the extraction block extends into or away from the fixture slot.

[0005] As a further embodiment of this utility model, the pull-out assembly also includes a pull-out seat, on which a sliding groove is provided through both sides, and the pull-out block is slidably installed in the sliding groove.

[0006] As a further embodiment of this utility model: the end of the pull-out block is detachably provided with an extension block, the width of the extension block is less than the width of the fixture groove, and there are two positioning pins, which are respectively set on the top and bottom surfaces of the extension block, and the two positioning pins have different diameters.

[0007] As a further embodiment of this utility model: the pull-out block is provided with ear plates on both sides, and a fixing hole is provided on the ear plate. A fixing bolt is passed through the fixing hole. A threaded hole corresponding to the fixing hole is provided on the end of the pull-out block. The fixing bolt passes through the fixing hole and is screwed into the threaded hole.

[0008] As a further embodiment of this utility model: support pads are provided at the four corners of the bottom surface of the base.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: By setting up a jig seat and a pull-out component, the workpiece after injection molding and demolding is placed in the jig slot of the jig seat, and then the pull-out component pulls out the inner mold part, separating the inner mold part from the workpiece, thereby realizing the automated extraction of the inner mold part. The operation process is simple and fast, and the work efficiency is improved.

[0018] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0019] Please see Figures 1-5 In this embodiment of the present invention, a pulling fixture includes a base 1, a fixture seat 2, and a pulling component 3. The fixture seat 2 is disposed on the top surface of the base 1, and a fixture groove 21 is provided on the top surface of the fixture seat 2. The pulling component 3 is disposed on the top surface of the base 1 and located on one side of the fixture seat 2. The pulling component 3 includes a driving member 31 and a pulling block 32. A positioning pin 33 is provided on the top surface of the pulling block 32 near its end. The starting end of the pulling block 32 is connected to the output end of the driving member 31. The driving member 31 can drive the pulling block 32 to move along the length direction of the base 1 so that the end of the pulling block 32 extends into or away from the fixture groove 21.

[0020] like Figure 1 As shown, the inner mold 4 has a positioning hole 41. In use, the inner mold 4 is placed in the fixture slot 21, and the positioning pin 33 located in the fixture slot 21 extends into the positioning hole 41. Then, the driving component 31 drives the extraction block 32 to move, so that the end of the extraction block 32 moves away from the fixture slot 21. When the extraction block 32 moves, it drives the inner mold 4 and the workpiece 5 to move together. When the workpiece 5 moves to the point of contacting the fixture seat 2, the fixture seat 2 restricts the workpiece 5 from moving further, while the extraction block 32 continues to drive the inner mold 4 to move, so that the inner mold 4 is separated from the workpiece 5. This realizes the automated extraction of the inner mold 4. The operation process is simple and fast, and the work efficiency is improved.

[0021] The pull-out assembly 3 also includes a pull-out seat 34, on which a sliding groove 35 extends through both sides. The pull-out block 32 is slidably mounted within the sliding groove 35. The sliding groove 35 prevents the pull-out block 32 from shifting during movement.

[0022] An infrared transmitter 22 and an infrared receiver 23 are provided on the side of the fixture base 2 near the extraction component 3. The infrared transmitter 22 and the infrared receiver 23 are arranged opposite each other and spaced apart on both sides of the fixture slot 21. With the arrangement of the infrared transmitter 22 and the infrared receiver 23, if the workpiece 5 is mistakenly placed in the wrong position, the workpiece 5 will block the infrared light emitted by the infrared transmitter 22. When the infrared receiver 23 does not receive the infrared light emitted by the infrared transmitter 22, the drive component 31 will stop working, preventing the drive component 31 from continuing to work and causing the extraction block 32 to damage the incorrectly placed workpiece 5.

[0023] The end of the pull-out block 32 is detachably equipped with an extension block 36. The width of the extension block 36 is smaller than the width of the fixture groove 21. There are two positioning pins 33, which are respectively located on the top and bottom surfaces of the extension block 36. The two positioning pins 33 have different diameters. In this way, during use, the positioning pins 33 of different diameters can be switched by rotating the extension block 36, so as to adapt to the inner mold parts 4 of different specifications, thereby improving the versatility and changeover efficiency of the fixture.

[0024] To facilitate the disassembly and installation of the pull-out block 32, ear plates 37 are provided on both sides of the pull-out block 32. Fixing holes 38 are provided on the ear plates 37, and fixing bolts 310 are passed through the fixing holes 38. A threaded hole 39 corresponding to the fixing hole 38 is provided at the end of the pull-out block. The fixing bolts 310 pass through the fixing holes 38 and are screwed into the threaded holes 39.

[0025] To ensure that the base 1 is placed more stably, support pads 11 are provided at the four corners of the bottom surface of the base 1.

[0026] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
