Description

Technical Field

[0001] This utility model relates to the field of machining, and in particular to a handheld copper thread feeding device. Background Technology

[0002] Traditional copper thread processing involves manually inserting copper threads of different sizes one by one into the designated area of ​​the injection mold. Since the size, weight, and number of individual copper threads vary, and the mounting surface is vertical, installation needs to be done in two stages. Manually inserting them one by one into the mold is prone to missing or inaccurate placement, which can lead to mold clamping damage.

[0003] Existing invention patent CN114603053A discloses a copper nut punching and feeding device, particularly relating to the field of copper nut processing technology. It includes a base frame, forward and reverse motors, a glue tank, a feeding rack, and a screw. The forward and reverse motors are installed inside the base frame, and the feeding rack is welded above the base frame. The glue tank is located on the left side of the feeding rack, and the screw is located inside the feeding rack. A lid is threaded onto the top of the glue tank, and a back plate is fixedly connected to the right end of the glue tank. Several evenly arranged springs are fixedly connected between the right end of the back plate and the left side of the feeding rack. The beneficial effect of this invention is that the sleeve can move upwards along with the screw tube. Furthermore, since the outer side of the ball bearing is impregnated with lubricant, when the sleeve moves upwards and the ball bearing rolls together, the lubricant impregnated on the outer side of the ball bearing can be evenly applied to the screw, lubricating it. This eliminates the need to disassemble the copper nut punching and feeding device, thus solving the problem of inconvenient lubrication of internal parts in existing copper nut punching and feeding devices. Utility Model Content

[0004] Due to production needs, copper threads are currently inserted into the mold one by one by hand. This method is prone to omissions or inaccuracies, leading to mold clamping damage. If the threads are not inserted properly, the product will be scrapped, or even irreversible damage may occur when the mold closes due to impact with the copper threads.

[0005] To solve the above problems, the technical solution provided by the present invention is as follows: a handheld copper thread feeding device, comprising a fixed baffle, the fixed baffle having a plurality of downwardly extending cylindrical push rod cores; fixed rods at the four corners of the fixed baffle having downwardly extending fixed rods, and a movable baffle having a sliding hole at the four corners of the movable baffle through which the fixed rods pass; a plurality of push rod sleeves corresponding to the push rod cores on the movable baffle, the push rod sleeves being fitted around the corresponding push rods; and two upwardly extending pressure guide rods on the movable baffle, the pressure guide rods passing upwardly through guide holes in the fixed baffle, the upper ends of the two pressure guide rods being connected and fixed to a pressure plate.

[0006] Specifically, the lower end of the push rod's inner core is equipped with a glass ball screw; the sliding holes at the four corners of the movable baffle pass through the fixed rod, allowing the movable baffle to move up and down on the fixed rod. The fixed rod can be fixed in the corresponding hole in the mold for accurate positioning.

[0007] Specifically, linear bearings are provided at the upper ends of the fixing rods at the four corners of the fixed baffle where they connect to the fixed baffle. The linear bearings limit the sliding of the movable baffle.

[0008] Specifically, a spring is installed on the upper part of the pressure guide rod that extends beyond the fixed baffle. The upper end of the spring presses against the pressure plate, and the lower end abuts against the fixed baffle. The spring enables the movable baffle to automatically reset.

[0009] Specifically, the fixed baffle has a handle located below the pressure plate. The push rod sleeve is fitted onto the outside of the corresponding push rod, but the two are not fixedly connected.

[0010] Specifically, the copper threaded material is secured by a glass ball screw inserted into the ejector sleeve. During use, the material is inserted into the ejector sleeve and secured by the glass ball screw at the lower end of the ejector core. The mold is accurately positioned using a fixing rod, and then the pressure plate is pressed down. The pressure plate drives the movable baffle to press down, and the ejector core on the movable baffle precisely presses the material into the mold.

[0011] The beneficial effects of this utility model are that, during use, all copper threads can be installed on the handheld device when idle. The inner core of the push rod contains glass ball screws that can lock the copper threads, so they will not fall off in any direction. During installation, simply align the positioning feet of the device with the holes in the mold, then grip it tightly, and the movable baffle will press the copper threads in the inner core of the push rod into position and firmly press them into place. The overall processing and feeding time is short, the positioning is accurate, and it is suitable for long-term repetitive work. Attached Figure Description
