Description
Technical Field
[0001] This utility model relates to the field of waste collection technology, specifically a waste collection device for hardware molds. Background Technology
[0002] In the metal processing industry, stamping dies are commonly used for stamping and hole-making. This process generates processing waste, which is often scattered around the equipment. This scattered waste cannot be collected and centrally processed in a timely manner, resulting in low cleaning efficiency in the work area. Furthermore, it requires regular manual cleaning, wasting a significant amount of time. Moreover, the collected waste is fragmented, making it inconvenient for transportation and storage. Utility Model Content
[0003] The purpose of this utility model is to provide a waste collection device for hardware molds to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a waste collection device for hardware molds, comprising:
[0005] A receiving hopper is slidably placed at the bottom of the lower die of a stamping mold. The receiving hopper is inclined and a connecting rod is fixedly connected to its bottom. A reset part is installed at one end of the connecting rod for driving the connecting rod to reset. A roller is rotatably connected to the outside of the connecting rod.
[0006] An extrusion slant plate is fixed to one side of the upper die of a stamping mold. One side of the extrusion slant plate is slidably connected to a roller, which is used to extrude the roller to move to one side.
[0007] A collection box is placed at one end of the receiving hopper. The collection box has two guiding structures inside, forming a discharge channel between the two guiding structures. A lifting plate is provided at one end of the collection box. An extrusion plate for compressing waste into blocks is slidably provided inside the collection box. A partition plate for blocking the discharge channel is fixed to one end of the top of the extrusion plate.
[0008] Preferably, the reset part includes a guide rail groove fixed to one side of the stamping die, a linear guide rail fixed inside the guide rail groove, a slider slidably connected to the outside of the linear guide rail, and a connecting rod fixed to the slider.
[0009] Preferably, one end of the slider is fixedly connected to a spring, one end of the spring is fixedly connected to the guide rail groove, and a support wheel is installed at the bottom of one end of the receiving hopper.
[0010] Preferably, a guide trough is fixedly connected to one inclined end of the receiving hopper, and the guide trough is located above the collection box.
[0011] Preferably, one end of the collection box is fixedly connected to a limiting slide plate, the lifting plate is slidably installed inside the limiting slide plate, a cylinder is fixedly connected to the outside of the limiting slide plate, and the output end of the cylinder is fixedly connected to one side of the bottom of the lifting plate.
[0012] Preferably, the two guiding structures are a guiding plate and an inclined plate, with the guiding plate fixed to the inner wall of the collection box and near the lifting plate, and the inclined plate fixed to the inner wall of the collection box away from the guiding plate.
[0013] Preferably, a hydraulic cylinder is fixedly connected inside the collection box, the output end of the hydraulic cylinder is fixedly connected to the extrusion plate, and the bottom of the inclined plate is slidably connected to the partition plate.
[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: Through the cooperation of the extrusion inclined plate, rollers, and reset part, when the upper die moves up and down reciprocally, the inclined surface of the extrusion inclined plate extrudes the rollers, causing the rollers to drive the receiving hopper to swing back and forth through the connecting rod. Through the movement of the die itself, without the need for an additional power source, the waste material falling from the lower die can be conveyed along the inclined direction of the receiving hopper. The guide plate set inside the collection box forms a feeding channel with the inclined plate. The guide plate has a right-angled triangular structure and the inclined surface is set downward, which is conducive to the smooth entry of waste material into the designated area. During the waste material conveying process, it can guide the waste material to fall accurately between the lifting plate and the partition plate, preparing for subsequent compression. The extrusion plate moves to one end under the drive of the hydraulic cylinder, compressing the waste material into a block structure, which is convenient for collection and storage. At the same time, the partition plate fixed to one end of the top of the extrusion plate blocks the guide structure when the extrusion plate moves, preventing the waste material from being placed on the side of the extrusion plate away from the lifting plate, ensuring the smooth progress of the compression process and the compression effect.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Please see Figure 1 , 2 As shown in Figures 3 and 4, this utility model provides a technical solution: a waste collection device for hardware molds, comprising: a receiving hopper 7 slidably installed at the bottom of the lower die of a stamping mold; the receiving hopper 7 is a metal groove with an opening at the top and one end; the receiving hopper 7 is installed below the waste discharge hole of the lower die; one end of the receiving hopper 7 is inclined downwards and its bottom is fixedly connected to a connecting rod 5; one end of the connecting rod 5 is equipped with a reset part for driving the connecting rod 5 to reset; a roller 6 is rotatably connected to the outside of the connecting rod 5; and an extrusion device fixedly connected to one side of the upper die of the stamping mold. Inclined plate 19, the extrusion inclined plate 19 is an isosceles triangle structure, the hypotenuse of the extrusion inclined plate 19 is slidably connected to roller 6, and is used to extrude roller 6 to move to one side; collection box 11 is placed at one end of receiving hopper 7, and two material guiding structures are set inside the collection box 11, forming a material discharge channel between the two material guiding structures. A lifting plate 18 is raised and lowered at one end of the collection box 11, and an extrusion plate 15 for compressing waste into blocks is slidably set inside the collection box 11. A partition plate 16 for blocking the material discharge channel is fixed to one end of the top of the extrusion plate 15.
[0022] It should be noted that in this embodiment, a controller and a timer are provided. The stamping equipment drives the upper die of the mold to move up and down reciprocally. When the upper die moves downward, it squeezes the inclined surface of the slant plate 19 to squeeze the roller 6, thereby pushing the roller 6 to one end. The roller 6 drives the receiving hopper 7 to move to one end through the connecting rod 5. When the upper die resets, the connecting rod 5 is driven at the reset part to drive the receiving hopper 7 to reset. This cycle is repeated to realize the back-and-forth swaying of the receiving hopper 7, thereby conveying the waste material falling from the lower die along the receiving hopper 7 inclined downward to the lifting plate 18, and entering between the lifting plate 18 and the partition plate 16 in the guide structure. Under the action of the timer, the controller controls the hydraulic cylinder 14 to drive the extrusion plate 15 to compress to one end, thereby compressing the waste material into a block structure for easy collection and storage. When the extrusion plate 15 moves downward to compress the waste material, the partition plate 16 blocks between the guide structures to prevent the waste material from entering the side of the extrusion plate 15 away from the lifting plate 18.
[0023] In one embodiment, the reset part includes a guide rail groove 1 fixed to one side of the stamping die, a linear guide rail 2 fixed inside the guide rail groove 1, a slider 3 slidably connected to the outside of the linear guide rail 2, a connecting rod 5 fixed to the slider 3, a spring 4 fixed to one end of the slider 3, and one end of the spring 4 fixed to the guide rail groove 1. A support wheel 8 is installed at the bottom of one end of the receiving hopper 7, and a guide groove 9 is fixed to the inclined end of the receiving hopper 7. The guide groove 9 is located above the collecting box 11.
[0024] It should be noted that in this embodiment, when the inclined surface of the extrusion plate 19 contacts the roller 6 and the roller 6 extrudes, the roller 6 drives the slider 3 to slide on the outside of the linear guide rail 2 via the connecting rod 5. The connecting rod 5 drives the receiving hopper 7 to move forward. The receiving hopper 7 moves horizontally forward under the support of the support wheel 8. During the sliding process, the slider 3 stretches the spring 4. When the extrusion plate 19 moves downward, the spring 4 drives the slider 3 to move in the opposite direction on the outside of the linear guide rail 2 when it resets. This cycle causes the connecting rod 5 to slide back and forth, thereby conveying the material falling into the receiving hopper 7 forward by shaking. Under the action of gravity, it slides into the collection box 11 through the guide chute 9.
[0025] In one embodiment, a limiting slide plate 10 is fixedly connected to one end of the collection box 11, and a lifting plate 18 is slidably installed inside the limiting slide plate 10. A cylinder 17 is fixedly connected to the outside of the limiting slide plate 10, and the output end of the cylinder 17 is fixedly connected to one side of the bottom of the lifting plate 18.
[0026] It should be noted that in this embodiment, a discharge port is provided at one end of the collection box 11, and the lifting plate 18 is installed at the position corresponding to the discharge port. The hydraulic cylinder 14 squeezes and compresses the lifting plate 18. When the limit switch corresponding to the hydraulic cylinder 14 is activated, the controller controls the cylinder 17 to lift the lifting plate 18 upward, so that the blocky waste can be pushed out through the hydraulic cylinder 14. After the hydraulic cylinder 14 is reset, the cylinder 17 drives the lifting plate 18 to reset.
[0027] In one embodiment, the two guiding structures are a guide plate 13 and an inclined plate 12. The guide plate 13 is fixed to the inner wall of the collection box 11 and close to one end of the lifting plate 18. The inclined plate 12 is fixed to the inner wall of the collection box 11 and away from the guide plate 13. A hydraulic cylinder 14 is fixed inside the collection box 11. The output end of the hydraulic cylinder 14 is fixed to the extrusion plate 15. The bottom of the inclined plate 12 is slidably connected to the partition plate 16.
[0028] It should be noted that in this embodiment, Hall switches are installed at both the end and the middle of the hydraulic cylinder 14, and a corresponding permanent magnet is installed at the piston position of the hydraulic cylinder 14. The guide plate 13 has a right-angled triangular structure with the inclined surface facing downwards. Under the action of the timer, the hydraulic cylinder 14 performs compression processing forward at regular intervals. When the hydraulic cylinder 14 drives the extrusion plate 15 to move to one end, the bottom of the top inclined plate 12 of the partition plate 16 is slidably connected. When the hydraulic cylinder 14 drives the extrusion plate 15 to extrude the waste material below the guide plate 13, the partition plate 16 is placed between the inclined plate 12 and the guide plate 13, blocking the falling waste material on the partition plate 16 between the inclined plate 12 and the guide plate 13. When the Hall switch located in the middle of the hydraulic cylinder 14 detects a signal, it transmits the signal to the controller. The controller stops the hydraulic cylinder 14 and controls the cylinder 17 to lift the lifting plate 18. Under the action of the timer, the hydraulic cylinder 14 drives the extrusion plate 15 to continue moving forward, thereby pushing the blocky waste material out from under the lifting plate 18. When the hydraulic cylinder 14 contacts the Hall switch located at the end, the controller connecting rod 5 resets the hydraulic cylinder 14, and the cylinder 17 drives the lifting plate 18 to block the outlet. The inclined plate 12 scrapes the material on the top of the partition plate 16 to one end of the extrusion plate 15. In this way, waste material can be cleaned without stopping the machine, and the compression facilitates storage and transportation.
