Description

Technical Field

[0001] The utility model relates to the field of clamping jig technology, in particular to a clamping jig used on a mold. Background Art

[0002] The structural forms of connecting wires are various, and they are usually composed of connectors and wires. Different connectors constitute different connecting wires, which can be used in different occasions. In the process of making these connecting wires, semi-finished connectors and wires are usually used. The semi-finished connectors are welded to the wires, and then placed in an injection mold to injection mold an SR injection molded part. The semi-finished connector and the wires are firmly connected together using the SR injection molded part, and at the same time, the semi-finished connector is formed into a finished product.

[0003] Normally, when making connecting wires, the semi-finished connectors and wires are directly implanted into the injection mold to form SR injection molded parts. This method has very low production efficiency. For this reason, there are currently multiple groups of support bar carriers that are placed off-line and implanted in turn. This carrier has a groove for carrying the semi-finished connectors. However, there is a gap between the groove of this carrier and the semi-finished connector. After the semi-finished connectors are placed, they are prone to loosening during the transfer process, resulting in a very high defective rate of the finished product after injection molding.

[0004] Therefore, it is necessary to study a solution to solve the above problems. Utility Model Content

In this embodiment, the forming block 20 is fixed by being embedded in the first receiving groove 13, and a plurality of the forming blocks 20 are arranged side by side horizontally, and each of them is fixed by being embedded in the corresponding first receiving groove 13.

[0037] The clamping assembly 30 is disposed on the main body 10 and in front of the forming block 20. The clamping assembly 30 includes a fixed seat 31, a fixed insert 32, a movable insert 33 and a reset member 34. The fixed seat 31 is fixed on the main body 10, and a fixing groove 301 that opens to one side and is used for receiving the semi-finished product 51 is recessed on the surface of the fixed seat 31. The fixing groove 301 communicates with the front end of the forming cavity 21. The fixed insert 32 is fixed on the main body 10. The movable insert 33 is disposed on the main body 10 so as to be able to move laterally back and forth. The movable insert 33 is located between the fixed seat 31 and the fixed insert 32. The reset member 34 is disposed between the movable insert 33 and the fixed insert 32. The reset member 34 urges the movable insert 33 to approach the fixed seat 31 to clamp the semi-finished product 51 in the fixing groove 301. In this embodiment, the clamping assembly 30 is fixed by being embedded in the first receiving groove 13. A guide post 302 protrudes from the side surface of the fixed seat 31 facing the movable insert 33. Correspondingly, a guide hole 303 is recessed on the side surface of the movable insert 33. The guide post 302 is inserted into the guide hole 303 and moves back and forth along the guide hole 303, so that the movement of the movable insert 33 is accurate and reliable. And, a first positioning hole 304 is recessed on the side surface of the fixed insert 32 facing the movable insert 33. Correspondingly, a second positioning hole 305 is recessed on the side surface of the movable insert 33. The reset member 34 is a linear spring, and both ends of the linear spring are respectively positioned by being embedded in the first positioning hole 304 and the second positioning hole 305, so that the reset member 34 is stably installed and the movable insert 33 can move closer to the fixed seat 31 better. And, there are two first positioning holes 304 arranged vertically. Correspondingly, there are also two second positioning holes 305 arranged vertically. The two second positioning holes 305 are respectively opposite to the two first positioning holes 304. There are two reset members 34, and both ends of the two reset members 34 are respectively positioned by being embedded in the corresponding first positioning hole 304 and the corresponding second positioning hole 305, so as to provide sufficient elasticity and clamp the semi-finished product 51 in the fixing groove 301 better. In addition, a plurality of the clamping assemblies 30 are arranged side by side horizontally, and the plurality of clamping assemblies 30 are respectively fixed by being embedded in the corresponding first receiving grooves 13 to clamp and fix a plurality of semi-finished products 51.

[0038] In addition, a wire clamping assembly 40 for clamping the wire 52 is provided on the body 10. The wire clamping assembly 40 is located behind the forming block 20 and is embedded in the second accommodating groove 14. Specifically, the wire clamping assembly 40 includes a fixed clamping block 41 and a movable clamping block 42. The fixed clamping block 41 is fixed on the body 10, and the movable clamping block 42 is laterally reciprocally movably arranged on the body 10 and is located on one side of the fixed clamping block 41. A wire clamping groove 401 for clamping the wire 52 is formed between the top of the movable clamping block 42 and the top of the fixed clamping block 41. The movable clamping block 42 is urged by a spring (not shown in the figure) to move closer to the fixed clamping block 41. Moreover, there are multiple wire clamping assemblies 40, and the multiple wire clamping assemblies 40 are respectively embedded in the corresponding second accommodating grooves 14 to clamp and fix multiple wires 52.

[0039] The usage method of this embodiment is described in detail as follows:

[0040] During use, after connecting the semi-finished product 51 (usually a connector) to the wire 52, then place the semi-finished product 51 directly above the fixed groove 301 and apply a downward pressure to the semi-finished product 51, so that the movable insert 33 is extruded and moves outward, and the reset member 34 is compressed. When the semi-finished product 51 is pressed down in place, the reset member 34 recovers its deformation and urges the movable insert 33 to move closer to the fixed seat 31, thereby firmly clamping the semi-finished product 51 in the fixed groove 301. Then, similarly apply a downward pressure to the wire 52 so that the wire 52 is clamped and fixed in the wire clamping groove 401. Finally, hold the handle 11 and place the product together with the semi-finished product 51 and the wire 52 into the injection mold to form an SR injection body in the forming cavity 21. The SR injection body is used to connect the wire 52 and the semi-finished product 51. When the forming is completed, just pull the finished product upward with force.

[0041] The design focus of the present utility model lies in: by providing a clamping assembly, using the reset member to urge the movable insert to move closer to the fixed seat to clamp the semi-finished product in the fixed groove. During operation, the operator only needs to apply a downward pressure to the semi-finished product to push the movable insert away, and then clamp the semi-finished product under the action of the reset member, effectively improving the yield of the finished product. The structure of this fixture is simple, and the pure mechanical structure makes the mold stable and reliable, with low maintenance cost.

[0042] As described above, it is only a preferred embodiment of the present utility model, and does not impose any limitation on the technical scope of the present utility model.
