Detailed Description
The following embodiments are provided for illustrative purposes only and are not intended to limit the scope of the present invention. The following description will be given with the same/similar reference numerals as used for the same/similar elements.
Fig. 1A is a simplified schematic diagram of a clamping fixture 10 for a plug electrode 11 according to an embodiment of the invention. Although the drawings of the present embodiment illustrate two plug electrodes 11, the present invention can also be applied to a single plug electrode 11. In the present embodiment, a single plug electrode 11 can correspond to a single clamping assembly. Although two plug electrodes 11 and their corresponding clamping combinations are illustrated in the drawings, for convenience of description, the following embodiments are described with respect to a single clamping combination corresponding to a single plug electrode 11.
Referring to fig. 1A, according to an embodiment of the present invention, a clamping fixture 10 includes an upper mold 12, a lower mold 14, and a clamping guide 16. The clamp guide 16 is disposed between the upper mold 12 and the lower mold 14. The lower mold 14 has a slope 13, a positioning groove 18 and an abutting surface 15 opposite to the slope 13. The clamp guide 16 is movable along the inclined surface 13. The upper mold 12 has an opening 12a, and the opening 12a corresponds to the position of the positioning groove 18. The upper and lower molds 12 and 14 are separable from and joinable to each other. When the upper mold 12 is combined to the lower mold 14, the upper mold 12 pushes the clamping guide 16 to move toward the lower mold 14, and the clamping guide 16 is also guided by the inclined surface 13 to move.
Before the clamping fixture 10 clamps the plug electrode 11, the upper mold 12 and the lower mold 14 are separated from each other. At this time, the holding jig 10 is located at the open position. When the clamping fixture 10 is to clamp the plug electrode 11, the plug electrode 11 enters the clamping fixture 10 through the opening 12a, and one end of the plug electrode 11 is positioned by the positioning slot 18. Subsequently, the upper die 12 is engaged with the lower die 14, and at this time, the holding guide 16 is pushed by the upper die 12 and guided by the inclined surface 13 to approach the abutting surface 15, and holds the plug electrode 11 together with the abutting surface 15. At this time, the clamping jig 10 is located at the clamping position. According to the above, when the plug electrode 11 enters the clamping jig 10 through the opening 12a, the clamping guide 16 does not approach the abutting surface 15 yet and clamps the plug electrode 11, so that the surface of the plug electrode 11 is not scratched by the clamping guide 16.
Referring to fig. 1B, fig. 1B is a simplified schematic diagram illustrating a clamping fixture 10 for a plug electrode 11 according to another embodiment of the invention. Unlike the previous embodiment, in the clamping fixture 10 of this embodiment, the single clamping assembly corresponding to the single plug electrode 11 includes two clamping guide blocks 16, and the lower mold 14 has two corresponding inclined surfaces 13. When the upper mold 12 is combined in the direction of the lower mold 14, the two clamping guide blocks 16 are pushed by the upper mold 12 and guided by the inclined surface 13 to approach each other, and clamp the plug electrodes 11 together. Similarly, when the plug electrode 11 enters the clamping fixture 10 through the opening 12a, the two clamping guide blocks 16 do not clamp the plug electrode 11 yet, so the surface of the plug electrode 11 is not scratched by the clamping guide blocks 16.
According to the above, the plug electrode 11 is not easily scratched by the clamping jig 10 when entering the clamping jig 10 through the clamping guide block 16 capable of sliding up and down, and in addition, after the plug electrode 11 enters the clamping jig 10, the clamping jig 10 enables the clamping guide block 16 to stably clamp the plug electrode 1 by combining the upper die 12 and the lower die 14, so that the plug electrode 11 is not easily deformed or displaced due to the influence of the injection pressure, and the dimensional stability and quality of the product are further improved. The following description will be directed to an embodiment of a detailed structure of the clamping jig.
Fig. 2A is an exploded view of a clamping fixture 100 for a plug electrode 101 according to an embodiment of the invention. Fig. 2B is an exploded view of the clamping fixture 100 of the plug electrode 101 of fig. 2A from a bottom view. Fig. 2C is a schematic diagram showing the relative positions of the plug electrode 101, the clamping guide block 106 and the abutting surface 108 before clamping.
According to an embodiment of the present invention, the clamping fixture 100 of the plug electrode 101 can be used for clamping 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 fixture 100 releases the plug electrodes 101 to complete the plug product.
Referring to fig. 2A and 2B, although two plug electrodes 101 and their corresponding clamping combinations are illustrated, for convenience of description, a single clamping combination corresponding to a single plug electrode 101 is described below. The clamping fixture 100 of the plug electrode 101 includes an upper mold 102, a lower mold 104 and a clamping guide 106. The upper mold 102 and the lower mold 104 are connected by a plurality of fixing posts 109, for example. The clamp guide 106 is disposed between the upper mold 102 and the lower mold 104. The lower mold 104 includes an inclined guiding slot 1041, and the inclined guiding slot 1041 has an inclined surface 1031. The lower mold 104 further includes a positioning groove 105 and an abutting surface 108 opposite to the inclined surface 1031. The clamp guide 106 is movable along the inclined surface 1031. The abutting surface 108 and the clamping guide 106 have a slot S1 therebetween, as shown in fig. 2C. The upper mold 102 has an opening 1023, and the opening 1023 corresponds to the slot S1 and the positioning groove 105. The upper die 102 and the lower die 104 may be separated from and combined with each other. When the upper mold 102 is combined with the lower mold 104, the upper mold 102 pushes the clamping guide 106 to move toward the lower mold 104, and the clamping guide 106 is guided by the inclined surface 1031 to move, so as to clamp the plug electrode 101 together with the abutting surface 108.
In this embodiment, the clamp guide 106 is slidably disposed on the upper mold 102 and the lower mold 104. Referring to fig. 2A to 2C, the upper mold 102 has a horizontal sliding groove 1021, and the clamping guide 106 has a horizontal sliding block 1065 and an inclined guide block 1061. The horizontal sliding block 1065 is correspondingly disposed in the horizontal sliding groove 1021 and can slide along the horizontal sliding groove 1021, and the inclined guiding block 1061 is correspondingly disposed in the inclined guiding groove 1041 and can slide along the inclined surface 1031 of the inclined guiding groove 1041. According to the above, when the upper mold 102 is combined with the lower mold 104, the upper mold 102 pushes the clamping guide 106 to move toward the lower mold 104, and the clamping guide 106 can move under the guidance of the inclined surface 1031, so as to clamp the plug electrode 101 together with the abutting surface 108.
In addition, in this embodiment, since the horizontal slider 1065 of the clamping guide 106 is disposed in the horizontal sliding slot 1021 of the upper mold 102 and is limited to move horizontally along the horizontal sliding slot 1021, when the upper mold 102 and the lower mold 104 are separated from each other, the upper mold 102 can drive the clamping guide 106 to move upward by the limitation between the horizontal slider 1065 and the horizontal sliding slot 1021, and at this time, the clamping guide 106 is also guided by the inclined surface 1031 to move, and further moves away from the abutting surface 108 to release the plug electrode 101.
In addition, referring to fig. 2C, before clamping, a slot S1 is formed between the abutting surface 108 and the clamping guide 106, and the slot S1 is larger than the thickness of the plug electrode 101. Therefore, when the plug electrode 101 is inserted, the plug electrode 101 and the clamping fixture 100 can be prevented from being scratched due to friction. When the upper mold 102 is engaged with the lower mold 104, the clamping guide 106 moves toward the abutting surface 108 to clamp the plug electrode 101 together with the abutting surface 108 under the pushing of the upper mold 102 and the guiding of the inclined surface 1031. When the upper mold 102 is separated from the lower mold 104, the clamping guide 106 is moved away from the abutting surface 108 to release the plug electrode 101 under the driving of the upper mold 102 and the guiding of the inclined surface 1031, and the state returns to that shown in fig. 2C. Therefore, when the plug electrode 101 is pulled out, the plug electrode 101 and the clamping fixture 100 can be prevented from being scratched due to friction.
In addition, in order to further reduce the friction between the plug electrode 101 and the clamping fixture 100, referring to fig. 2C, in an embodiment, at least one roller 1081 may be disposed on the abutting surface 108. The number of the rollers 1081 is, for example, one or two, and when the number of the rollers 1081 is one, the position thereof may be located at the center of the abutting surface 108, and when the number of the rollers 1081 is two, the position thereof may be located at the upper and lower sides of the abutting surface 108, so as to increase the stability of the clamping, but the invention is not limited thereto. The roller 1081 can be in rolling contact with the plug electrode 101 inserted into the clamping fixture 100, so that the plug electrode 101 is not scratched by friction when being inserted into or pulled out of the clamping fixture 100.
In addition, referring to fig. 2C, in an embodiment, a side of the clamping guide block 106 corresponding to the plug electrode 101 has a bump 1063. The number and positions of the protrusions 1063 may correspond to those of the rollers 1081, but the invention is not limited thereto. The protrusion 1063 can cooperate with the corresponding roller 1081 to clamp the plug electrode 101, so as to increase the stability of clamping. Furthermore, the design of the protrusion 1063 of the clamping guide 106 can reduce the area of the clamping guide 106 that may rub against the plug electrode 101, thereby reducing the friction between the plug electrode 101 and the clamping fixture 100.
In addition, referring to fig. 2A, in an embodiment, the lower mold 104 of the clamping fixture 100 further includes a vertical positioning element 110 for determining a vertical positioning position of the plug electrode. In this embodiment, the positioning groove 105 extends along a vertical direction (i.e., the direction in which the plug electrode 101 is inserted and extracted), and the vertical positioning element 110 is disposed in the extending direction of the positioning groove 105. When the plug electrode 101 is inserted into the clamping fixture 100, one end of the plug electrode 101 abuts against the vertical positioning member 110. In this embodiment, the extending direction of the vertical positioning element 110 is perpendicular to the extending direction of the positioning slot 105, and the holding fixture 100 can determine the vertical positioning position of the plug electrode 101 according to the position of the vertical positioning element 110.
Fig. 3A is an assembly view of the clamping fixture 100 of fig. 2A. Fig. 3B is a cross-sectional view along the line a-a of the clamping fixture 100 of fig. 3A in the open position. Fig. 3C is a cross-sectional view along the line a-a of the clamping fixture 100 of fig. 3A at the clamping position.
Referring to fig. 3B and 3C, the upper mold 102 and the lower mold 104 can be separated from and combined with each other. When the clamping fixture 100 is in the open position, as shown in fig. 3B, the upper mold 102 and the lower mold 104 are separated from each other, and the plug electrode 101, the clamping guide 106 and the abutting surface 108 are loosely fitted. As shown in fig. 2C, the abutting surface 108 and the clamping guide 106 have an insertion slit S1 therebetween, and the insertion slit S1 is larger than the thickness of the plug electrode 101. When the upper mold 102 is combined with the lower mold 104, the upper mold 102 pushes the clamping guide 106 to move toward the lower mold 104, and the clamping guide 106 is guided by the inclined surface 1031 to move, so as to clamp the plug electrode 101 together with the roller 1081 of the abutting surface 108. At this time, when the clamping fixture 100 is in the clamping position, as shown in fig. 3C, the upper mold 102 and the lower mold 104 are combined with each other, and the plug electrode 101, the clamping guide block 106 and the abutting surface 108 are tightly fitted. Then, when the upper mold 102 is separated from the lower mold 104, the clamping guide 106 is moved away from the first roller 1081 to release the plug electrode 101 under the driving of the upper mold 102 and the guiding of the inclined surface 1031, and the state of fig. 3B is returned.
According to the above, when the clamping fixture 100 is in the open position, the plug electrode 101, the clamping guide block 106 and the abutting surface 108 are loosely fitted, so that when the plug electrode 101 is inserted into and pulled out of the clamping fixture 100, the plug electrode 101 and the clamping fixture 100 can be effectively prevented from being scratched due to friction. In addition, since the clamping fixture 100 is in the clamping position, the plug electrode 101, the clamping guide block 106 and the abutting surface 108 are tightly fitted, so that the problem that the plug electrode 101 is displaced under the injection pressure can be effectively avoided when the plastic injection molding process is performed.
Fig. 4A is an exploded view of a clamping fixture 200 for a plug electrode 201 according to another embodiment of the invention. Fig. 4B is an exploded view of the clamping fixture 200 of the plug electrode 201 of fig. 4A from a bottom view. Fig. 4C is a schematic diagram showing the relative positions of the clamping guide 206, the lower die 204 and the pushing member 207. Similarly, although two plug electrodes 201 and their corresponding clamping combinations are illustrated in the drawings, for convenience of description, a single clamping combination corresponding to a single plug electrode 201 is described below.
This embodiment is different from the previous embodiment in that it has two clamping guide blocks 206, and the plug electrode 201 is clamped by the two clamping guide blocks 206. In addition, when the upper die 202 is separated from the lower die 204, the holding guide 206 releases the plug electrode 201 by being pushed by a pushing member 207 of the lower die 204.
Referring to fig. 4A to 4C, the clamping fixture 200 of the plug electrode 201 includes an upper mold 202, a lower mold 204 and two clamping guide blocks 206. The lower die 204 and the upper die 202 are connected by a plurality of fixing posts 209, for example. The clamp guide 206 is disposed between the upper mold 202 and the lower mold 204. The clamp guides 206 have a slot S2 therebetween. The lower mold 204 includes an inclined guide groove 2041, and the inclined guide groove 2041 has two opposite inclined surfaces 2031. The lower mold 204 further includes a pushing member 207 disposed below the inclined guide groove 2041. The pushing member 207 has a positioning groove 208. The two clamping guide blocks 206 are accommodated in the inclined guide grooves 2041, respectively correspond to the two inclined surfaces 2031, and abut against the pushing member 207. The clamp guide 206 is movable along the corresponding ramp 2031. The upper mold 202 has an opening 2023, and the opening 2023 corresponds to the position of the slot S2 and the positioning groove 208. The upper mold 202 and the lower mold 204 may be separated from and combined with each other.
Similarly, in this embodiment, the slot S2 between the two clamping guides 106 is larger than the thickness of the plug electrode 201 before clamping. Therefore, when the plug electrode 201 is inserted, the plug electrode 201 and the clamping fixture 200 can be prevented from being scratched due to friction. When the upper mold 202 is engaged with the lower mold 204, the two clamping guides 106 approach each other and clamp the plug electrode 201 together under the pushing of the upper mold 202 and the guiding of the inclined surface 2031. When the upper mold 202 and the lower mold 204 are separated, the two clamping guide blocks 206 are moved away from each other to release the plug electrode 201 under the pushing of the pushing member 207 and the guiding of the inclined surface 2031. Therefore, when the plug electrode 201 is pulled out, the plug electrode 201 and the clamping fixture 200 can be prevented from being scratched due to friction.
Please refer to fig. 4C and fig. 5A to 5C. Fig. 5A is an assembly diagram of the clamping fixture 200 of fig. 4A. Fig. 5B is a cross-sectional view along line B-B of the clamping fixture 200 of fig. 4A in an open position. Fig. 5C is a cross-sectional view of the clamping fixture 200 of fig. 4A along the line B-B when in the clamping position.
In this embodiment, the pushing member 207 is disposed in the lower mold 204 to be movable up and down. In one embodiment, the lower mold 204 includes a base 2073 and at least one spring 2072 (two are shown). The spring 2072 is disposed between the pushing member 207 and the base 2073 for providing a pushing force to the pushing member 207, so that the clamping guide 206 abutting on the pushing member 207 can move upward under the pushing force.
Referring to fig. 5B and 5C, the upper mold 202 and the lower mold 204 can be separated from and combined with each other. When the clamping fixture 200 is in the open position, as shown in fig. 5B, the upper mold 202 and the lower mold 204 are separated from each other, and the plug electrode 201 and the two clamping guide blocks 106 are loosely fitted. When the upper mold 202 is engaged with the lower mold 204, the upper mold 202 pushes the clamping guide 206 to move toward the lower mold 204, and the clamping guide 206 is guided by the inclined surface 2031 to move, thereby clamping the plug electrode 201 together. Further, when the clamp guide 206 moves toward the lower mold 204, the clamp guide 206 pushes the pusher 207 downward and compresses the spring 2072. At this time, the clamping fixture 200 is in the clamping position, as shown in fig. 5C, the upper mold 202 and the lower mold 204 are combined with each other, and the plug electrode 201 and the two clamping guide blocks 206 are tightly fitted. Then, when the upper mold 202 is separated from the lower mold 204, the spring 2072 pushes the pushing member 207 upward, so that the pushing member 207 pushes the clamping guide 206. Under the driving of the pushing member 207 and the guiding of the inclined surface 2031, the two clamping guide blocks 206 move away from each other to release the plug electrode 201, and return to the state shown in fig. 5B. Thus, when the plug electrode 201 is inserted and pulled out, the clamping fixture 200 is located at the open position, and the plug electrode 201 and the two clamping guide blocks are loosely matched, so that the plug electrode 201 and the clamping fixture 200 can be effectively prevented from being scratched due to friction.
In addition, referring to fig. 4A, fig. 5B and fig. 5C, in an embodiment, the clamping fixture 200 further includes a vertical positioning element 210 for determining a vertical positioning position of the plug electrode 202. In this embodiment, the positioning groove 208 extends in a vertical direction (i.e., the direction in which the plug electrode 201 is inserted and extracted), and the vertical positioning member 210 is disposed in the positioning groove 208. When the plug electrode 201 is inserted into the clamping fixture 200, one end of the plug electrode 201 abuts against the vertical positioning member 210. In this embodiment, the extending direction of the vertical positioning element 210 is parallel to the extending direction of the positioning slot 208, and the holding fixture 200 can determine the vertical positioning position of the plug electrode 201 according to the extending length of the vertical positioning element 210.
The different structural designs of the above embodiments may be used in alternate combinations. For example, in one embodiment, a single clamping assembly corresponding to a single plug electrode can use a single clamping guide and an abutting surface design to clamp the plug electrode, and use a pushing member design to push the clamping guide to release the plug electrode. For example, in another embodiment, the single clamping combination corresponding to a single plug electrode can use the design of two clamping guide blocks to clamp the plug electrode, and use the design of the horizontal sliding block and the horizontal sliding groove of the upper mold to drive the clamping guide blocks to release the plug electrode.
The above embodiment is described with reference to a single clamping combination corresponding to a single plug electrode, but the present invention is not limited thereto, and when the clamping fixture needs to clamp a plurality of plug electrodes, the clamping fixture may be provided with a corresponding clamping combination for each plug electrode according to the above embodiment. As shown in the drawings of the present embodiment, two plug electrodes and their corresponding clamping assemblies are shown.
Compared with the conventional method, the clamping jig for the plug electrode disclosed by the embodiment of the invention can ensure that the plug electrode is not easily influenced by the ejection pressure to generate displacement and is not easily scratched by the jig, thereby improving the dimensional stability of a product.
In summary, although the present invention has been described with reference to the above embodiments, the present invention is not limited thereto.
The present invention is capable of other embodiments, and various changes and modifications may be made by one skilled in the art without departing from the spirit and scope of the invention as defined in the appended claims.
