Description

Plug electrode clamping fixture

The present invention relates to a clamping fixture, and more particularly to a clamping fixture for a plug electrode.

In the process of plastic injection molding, the conventional plug body needs to first clamp and fix the plug electrode by using a clamping fixture. In order to avoid the displacement of the plug electrode due to the injection pressure during the plastic injection molding process, the dimensional stability of the plug product is not good, and it is generally required to make a tight fit between the clamping fixture and the plug electrode. However, in this case, when the plug electrode is inserted and pulled out of the clamp jig, the plug electrode is easily scratched by the clamp jig due to friction, thereby affecting the quality of the product.

The invention relates to a clamping fixture for a plug electrode, which can make the plug electrode less susceptible to displacement due to the injection pressure, and is not easily scratched by the fixture, thereby improving the dimensional stability and quality of the product.

According to an aspect of the invention, a clamping jig for a plug electrode is provided, comprising an upper die, a lower die and at least one clamping guide. The lower mold and the upper mold may be separated or combined with each other, wherein the upper mold has at least one opening such that at least one plug electrode is inserted through the opening. At least one clamping guide is disposed between the upper die and the lower die for clamping or releasing at least one plug electrode. The lower mold has a sloped surface. When the upper mold is coupled to the lower mold direction, the upper mold pushes the clamping guide block to move in the direction of the lower mold, and the clamping guide block is guided by the inclined surface to move to clamp at least one plug electrode.

In order to better understand the above and other aspects of the present invention, the following detailed description of the embodiments and the accompanying drawings

The embodiments are described in detail below, and the embodiments are only intended to be illustrative and not intended to limit the scope of the invention. The same/similar symbols are used to describe the same/similar elements.

FIG. 1A is a simplified schematic view of the clamping jig 10 of the plug electrode 11 according to an embodiment of the invention. Although the drawing of the present embodiment is shown to hold the two plug electrodes 11, it is also suitable for holding a single plug electrode 11. In this embodiment, a single plug electrode 11 can correspond to a single clamp combination. Although the two plug electrodes 11 and their corresponding clamping combinations are shown in the figure, for convenience of description, the following embodiments are directed to a single clamping group cooperation description corresponding to a single plug electrode 11.

Referring to FIG. 1A, in accordance with an embodiment of the present invention, the clamping jig 10 includes an upper die 12, a lower die 14, and a clamping guide 16. The clamping guide 16 is disposed between the upper die 12 and the lower die 14. The lower mold 14 has a slope 13 , a positioning groove 18 and an abutting surface 15 opposite to the inclined surface 13 . The clamping guide 16 is movable along the slope 13. The upper die 12 has an opening 12a corresponding to the position of the positioning groove 18. The upper mold 12 and the lower mold 14 can be separated and combined with each other. When the upper mold 12 is joined in the direction of the lower mold 14, the upper mold 12 pushes the holding guide 16 to move in the direction of the lower mold 14, and the holding guide 16 is also guided by the inclined surface 13 to move.

The upper mold 12 and the lower mold 14 are separated from each other before the clamp jig 10 is not clamped to the plug electrode 11. At this time, the grip jig 10 is in the open position. When the clamping jig 10 is intended to hold the plug electrode 11, the plug electrode 11 enters the clamping jig 10 via the opening 12a, and one end of the plug electrode 11 is positioned by the positioning groove 18. Then, the upper mold 12 is coupled in the direction of the lower mold 14, and at this time, the clamping guide 16 is guided by the upper mold 12 and guided by the inclined surface 13 to approach the abutting surface 15, and clamps the plug electrode together with the abutting surface 15. 11. At this time, the grip jig 10 is located at the gripping position. According to the above, since the plug guide 16 has not yet approached the abutting surface 15 to grip the plug electrode 11 when the plug electrode 11 enters the clamp jig 10 via the opening 12a, the surface of the plug electrode 11 is not clamped. Block 16 is scratched.

When the upper mold 12 is joined in the direction of the lower mold 14, the two holding guide blocks 16 are guided by the upper mold 12 and guided by the inclined surface 13 to approach each other, and the plug electrodes 11 are held together. Likewise, when the plug electrode 11 enters the clamping jig 10 via the opening 12a, the two clamping guides 16 have not yet gripped the plug electrode 11, so that the surface of the plug electrode 11 is not scratched by the clamping guide 16.

According to the above, the clamping electrode 16 that can slide up and down can prevent the plug electrode 11 from being scratched by the clamping jig 10 when entering the clamping jig 10, and further, after the plug electrode 11 enters the clamping jig 10 The clamping jig 10 combines the upper mold 12 and the lower mold 14 so that the clamping guide 16 firmly holds the plug electrode 1 so that the plug electrode 11 is less susceptible to deformation or displacement due to the injection pressure, thereby increasing the size of the product. Stability and quality. Hereinafter, an embodiment of the detailed structure of the clamp jig will be described.

FIG. 2C is a schematic view showing the relative positions of the plug electrode 101, the clamping guide 106 and the abutting surface 108 before clamping.

According to an embodiment of the present invention, the clamping jig 100 of the plug electrode 101 can be used to clamp the plug electrode 101 when the plug body is subjected to a plastic injection molding process. After the injection-molded plug body is integrated with the two plug electrodes 101, the clamping jig 100 releases the plug electrode 101 to complete the plug product.

Please refer to FIGS. 2A and 2B. Similarly, although the two plug electrodes 101 and their corresponding clamping combinations are shown, for convenience of description, the single clamping combination corresponding to the single plug electrode 101 is described below. Be explained. The clamping jig 100 of the plug electrode 101 includes an upper die 102, a lower die 104 and a clamping guide 106. The upper mold 102 and the lower mold 104 are connected, for example, by a plurality of fixing posts 109. The clamping guide 106 is disposed between the upper die 102 and the lower die 104. The lower mold 104 includes a slanted guide groove 1041 having a slope 1031. The lower mold 104 further includes a positioning groove 105 and an abutting surface 108 opposite to the inclined surface 1031. The clamping guide 106 is movable along the slope 1031. There is a slit S1 between the abutment surface 108 and the clamping guide 106, as shown in Fig. 2C. The upper mold 102 has an opening 1023 corresponding to the position of the slit S1 and the positioning groove 105. The upper mold 102 and the lower mold 104 can be separated and combined with each other. When the upper die 102 is coupled to the lower die 104, the upper die 102 pushes the clamping guide block 106 to move toward the lower die 104, and the clamping guide block 106 is also guided by the inclined surface 1031 to move, and thus the abutting surface 108. The plug electrodes 101 are held together.

In this embodiment, the clamping guides 106 are slidably disposed on the upper die 102 and the lower die 104. Referring to FIGS. 2A-2C, the upper mold 102 has a horizontal sliding slot 1021. The clamping guide 106 has a horizontal slider 1065 and a oblique guiding block 1061. The horizontal slider 1065 is correspondingly disposed in the horizontal sliding slot 1021 and can slide along the horizontal sliding slot 1021 , and the oblique guiding block 1061 is correspondingly disposed in the oblique guiding slot 1041 and can slide along the inclined surface 1031 of the oblique guiding slot 1041 . According to the above, when the upper die 102 is coupled in the direction of the lower die 104, the upper die 102 pushes the clamping guide block 106 to move in the direction of the lower die 104, while the clamping guide block 106 can be guided by the inclined surface 1031 to move, thereby The plug electrode 101 is held together by the face 108.

Further, in this embodiment, since the horizontal slider 1065 of the clamping guide 106 is disposed in the horizontal sliding groove 1021 of the upper mold 102 and is restricted to horizontally move along the horizontal sliding groove 1021, when the upper mold 102 is When the lower die 104 is separated from the upper and lower sides, the upper die 102 can move the clamping guide block 106 upward by the restriction between the horizontal slider 1065 and the horizontal sliding slot 1021.

In addition, referring to FIG. 2C, before the clamping, the abutting surface 108 and the clamping guide 106 have a slit S1, and the slit S1 is larger than the thickness of the plug electrode 101. Therefore, when the plug electrode 101 is inserted, the plug electrode 101 can be prevented from being scratched by the friction of the clamp jig 100. When the upper die 102 is joined in the direction of the lower die 104, under the pushing of the upper die 102 and the guiding of the inclined surface 1031, the clamping guide 106 is moved toward the abutting surface 108 to sandwich the plug electrode 101 together with the abutting surface 108. When the upper die 102 is separated from the lower die 104, under the driving of the upper die 102 and the guiding of the inclined surface 1031, the clamping guide 106 is moved away from the abutting surface 108 to release the plug electrode 101, and returns to the state shown in FIG. 2C. status. Thus, when the plug electrode 101 is pulled out, the plug electrode 101 can be prevented from being scratched by the friction of the clamp jig 100.
