Description

Technical Field

[0001] The utility model relates to the technical field of jigs, in particular to a jig suitable for inlaying pins of different heights. Background Art

[0002] Pins are a crucial component of injection molds. Depending on their shape, they can be categorized as flat, straight, or stepped. These different pin types are used to meet diverse mold design and processing requirements. Pins generally serve several functions, including venting, facilitating processing and maintenance, improving mold strength, saving materials and reducing costs, and shortening manufacturing cycles.

[0003] The pins used in molds for manufacturing automotive lamps require CNC machining of a patterned, concave arc surface at the end of the pins. Furthermore, the length of the pins in each automotive lamp mold varies. If many pins are required, machining them one by one is very costly. Therefore, a jig is needed to mass-produce these pins. This paper proposes a jig suitable for producing pins of varying heights to address these challenges. Utility Model Content

[0026] Example 1

[0027] like Figure 2 、 Figure 3 As shown, a jig suitable for inlay pins 1 of different heights comprises a jig top plate 2, a plurality of connecting posts 3 of the same height, and a jig base 4, which are connected in sequence from top to bottom. The plurality of connecting posts 3 are detachably mounted between the jig top plate 2 and the jig base 4, and the connecting posts 3 are provided with a plurality of groups of different heights for replacement to match inlay pins 1 of different heights, thereby increasing the breadth of use of the jig in this embodiment, and can be used on inlay pins 1 of various heights; a plurality of sockets 5 for placing the inlay pins 1 are respectively provided on the jig top plate 2 and the jig base 4, and each inlay pin 1 is interference fit with the socket 5, so that the inlay pin 1 is inserted into the socket 5 and fixed on the jig; the head of each inlay pin 1 is in the shape of a column with a notch, and the bottom surfaces of the jig top plate 2 and the jig base 4 are provided with a plurality of notches 6 (such as Figure 4 As shown). A plurality of jacks 5 are arranged in a rectangular array, and a plurality of notches 6 are arranged along the transverse or longitudinal direction of the rectangular array; the cutout of the head of the inlay pin 1 is a cut surface 7 (as shown). Figure 1 As shown), when the insert pin 1 is inserted into the socket 5, the cut surface 7 of the head of the insert pin 1 fits on the side wall of the slot 6; thereby, the insert pin 1 does not rotate during CNC processing.

[0028] The jig base 4 is a regular square plate. The bottom surface of the jig top plate 2 is horizontal, while the top surface of the jig top plate 2 is a stepped surface 8 that gradually rises in one direction. The insertion holes 5 are distributed on different steps. When the pin 1 is inserted into the insertion hole 5, the tail of the pin 1 is exposed on the top surface of the jig. The stepped surface 8 of the jig top plate 2 makes the jig suitable for pins 1 with small height differences. At the same time, the exposed tail of the pin 1 is not too far from the top surface of the jig, which prevents vibration of the pin 1 during CNC machining and improves the precision of the concave arc surface of the pin 1 tail.

[0029] The height of the head of the inlay pin 1 is the same as the depth of the slot 6. The lower openings of the sockets 5 on both the top plate 2 and the base 4 of the jig are chamfered. Multiple connecting posts 3 are arranged around the circumference of the sockets 5. Screw holes are defined along the axial direction at the upper and lower ends of the connecting posts 3. Screw holes are also defined vertically through the top plate 2 and base 4 of the jig. The connecting posts 3 are removably mounted between the top plate 2 and base 4 using screws.

[0030] Example 2

[0031] The difference between the second embodiment and the first embodiment is that Figure 5 As shown, the jig base 4 is a regular square plate. The bottom surface of the jig top plate 2 is a horizontal plane, and the top surface of the jig top plate 2 is an inclined surface 9 that gradually rises in one direction. When the pin 1 is inserted into the socket 5, the tail of the pin 1 is exposed on the top surface of the jig. Similarly, the jig top plate 2 is configured with an inclined surface 9, which makes the jig suitable for pins 1 with a small height difference. At the same time, the tail of the pin 1 is not too much exposed from the top surface of the jig, which prevents vibration of the pin 1 during CNC machining and improves the precision of the concave arc surface of the tail of the pin 1.
