[0002] The mold ejector is an accessory used in the mold. Most existing mold ejectors are round ejector rods with equal outer diameter. The mold ejector is installed in the mounting hole in the mold. After the product is injection molded or stamped, the molded product is removed from the mold through the action of the mold ejector, thereby realizing the process of unloading.

[0003] During the processing of ejector molds, the long strip of raw materials is cut, fine-tuned, and headed to form an ejector semi-finished product. Heading is to treat one end of the ejector with high temperature and embed it into a mold with a hole to deform the end of the ejector to form a die head. The heading equipment in the prior art is semi-automatic processing, with low processing efficiency and often requires manual operation. Therefore, we propose a fully automatic heading equipment for mold ejector pins. Utility Model Content

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] refer to Figure 1-2 A fully automatic head-punching device for a mold ejector includes a raw material rod 9, and also includes: a base; a clamping fixture 2, which is slidably mounted on the base, and the clamping fixture 2 is repeatedly pushed by a driver 21, and a clamping hole 25 is provided on the clamping fixture 2. A positioning tray 3 is mounted on the base and located at one end of the clamping fixture 2, and is used to carry the raw material rod 9 and make the raw material rod 9 correspond to the clamping hole 25. The pusher 4 is installed on one side of the positioning tray 3, and pushes the mold ejector from the positioning tray 3 into the clamping fixture 2 for clamping; the electromagnetic induction heating machine 5 is installed on the bottom plate 411, and includes a heating coil 51 located at the other end of the positioning tray 3 and corresponding to the clamping hole 25; the die head 6 is movably installed on the side of the heating coil 51 away from the positioning tray 3, and a recessed die hole is provided at the end of the die head 6 close to the heating coil 51. After the heating coil 51 heats the raw material rod 9, it is inserted into the die head 6 for heading forming; the unloading robot 7 is installed on the side of the clamping fixture 2 that is axially perpendicular to the clamping hole 25, and unloads the raw material rod 9 after heading forming.

[0024] It can be understood that the clamping fixture 2 is a prior art, for example, a bidirectional clamping pneumatic mechanism is used, and a cylindrical clamping mechanism can also be used. The sliding installation of the clamping fixture 2 can be installed on the bottom plate 411 with a slide rail 22, and a slider 23 is installed on the slide rail 22. The clamping fixture 2 is installed on the slider 23, and the output end of the driver 21 is connected to the slider 23. Of course, sliding structures such as slide rails 22 pulleys can also be used. The driver 21 pushes the slider 23 to slide, and its driver 21 can set a stroke, that is, control the sliding distance of the slider 23. However, for the sake of safety, limit plates 24 for limiting the position of the slider 23 are installed at both ends of the slide rail 22. The limit plate 24 can limit the sliding position of the slider 23. The pusher 4 and the heating coil 51 are located at the axial ends of the clamping hole 25 of the clamping fixture 2, and the pusher 4 also uses a cylinder, an electric push rod and other pushing parts. The electromagnetic induction heating machine 5 is a prior art, which heats the raw material rod 9 inserted in the heating coil 51 by electromagnetic induction principle. This is a prior art and will not be described in detail here. The driver 21 can also use a telescopic and movable drive member such as a cylinder, a motor and a threaded screw drive.

[0025] In this way, the raw material rod 9 is placed on the positioning tray 3, the pusher 4 pushes the raw material rod 9 into the clamping hole 25 of the clamping fixture 2, and the end of the raw material rod 9 close to the die head 6 is inserted into the heating coil 51. When the raw material rod 9 is heated to a certain temperature and softened, the driver 21 drives the clamping fixture 2 to insert the heated end of the clamped raw material rod 9 into the die head 6 for head forming, thereby completing the automatic head forming. An automatic unloading device can be installed above the positioning tray 3 to place the raw material rods 9 one by one on the positioning tray 3. When unloading, since the raw material rod 9 is inserted into the heating coil 51 and cannot be directly moved up and down to be taken, the driver 21 is required to drive the clamping fixture 2 to return the clamped raw material rod 9 to the position until the raw material rod 9 completely exits the heating coil 51, and the unloading robot 7 clamps the raw material rod 9, and the clamping fixture 2 releases the clamping of the raw material rod 9 and retreats to make the raw material rod 9 separate from the clamping fixture 2, and the unloading robot 7 transfers the raw material rod 9 to complete the automatic unloading.

[0026] refer to Figure 1 and Figure 3In some embodiments, since the position of the clamping hole 25 of the clamping fixture 2 is a certain distance from the bottom plate 411, the positioning tray 3 is installed with a spacing from the bottom plate 411 through the support rod 8. Similarly, the pusher 4 is installed on the bottom plate 411, and the bottom plate 411 is spaced from the base through the support rod 8 to ensure that the height position of the pusher 4 is better for pushing the raw material on the positioning tray 3. The top surface of the positioning tray 3 is an arc groove 31 adapted to the raw material rod 9. In order to ensure that the raw material rod 9 can be smoothly pushed into the clamping hole 25, the axis of the arc groove 31 is further set to be on the same horizontal line as the axis of the clamping hole 25. Furthermore, since the pusher 4 is located on one side of the positioning tray 3 and is not coaxial with the axial direction of the raw material rod 9, a cross bar 42 extending toward the positioning tray 3 is connected to the output end of the pusher 4, and a top rod 43 located in the arc groove 31 and pushing the raw material rod 9 is installed at the end of the cross bar 42 away from the pusher 4. In this way, the pusher 4 drives the push rod 43 through the cross rod 42 to act on the raw material rod 9 to perform pushing work.

[0027] In some embodiments, the die head 6 is mounted on a swing rod 61, and one end of the swing rod 61 away from the die head 6 is slidably sleeved on a horizontally arranged adjusting rod 62, and the adjusting rod 62 is provided with a thread, and screw sleeves are threadedly installed on the adjusting rod 62 on both sides of the swing rod 61 to lock the swing rod 61. For the adjustment fixation, it can be fixed on the bottom plate 411 through a connecting piece such as a connecting rod, or it can be directly fixed on the electromagnetic induction heating machine 5. The swing rod 61 can be adjusted in position laterally on the adjusting rod 62, and can also be rotated to adjust the angle. After the position of the swing rod 61 is determined, it is locked in both directions through two screw sleeves.

[0028] In some embodiments, the unloading robot 7 includes a rotary cylinder 71 installed on the bottom plate 411, a vertical cylinder 72 installed on the output end of the rotary cylinder 71, a horizontal cylinder 73 installed on the output end of the vertical cylinder 72, and an air clamp 74 installed on the output end of the horizontal cylinder 73. When unloading, after the raw material is pushed out of the heating coil 51, the horizontal cylinder 73 drives the air claw to move toward the raw material rod 9, and clamps the raw material rod 9 through the air claw, and the vertical cylinder 72 moves up to the upper side of the heating coil 51, and then the raw material rod 9 is transferred by rotating the rotary cylinder 71. Here, a material storage frame can be installed on one side of the unloading robot 7 for receiving materials. The unloading robot 7 can also use a mechanical arm.

[0029] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
