Detailed Implementation

[0023] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0024] In the description of this application, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around", etc., which indicate orientation or positional relationship, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the component or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0025] Example

[0026] To address the issue of existing technologies using manual cutting methods, such as... Figure 1 The process of removing gate waste from the part to be punched, as shown, suffers from low work efficiency and high labor intensity for operators. (Refer to...) Figures 2-4 As shown, this application discloses a waste material punching machine, including a machine base 10, an indexing plate 20, and a punching mechanism 30. The indexing plate 20 is disposed on the machine base 10. The machine base 10 is provided with a loading reserved station 11, a punching station 12, and a unloading reserved station 13 in sequence along the rotation direction of the indexing plate 20. The loading station can be disposed near the injection molding machine to receive the parts to be punched taken out by the injection molding robot in the prior art. The punching station 12 is the operating position of the punching mechanism 30 of this application. The unloading reserved station 13 can be the standing position of the operator for recycling the punched products.

[0027] The indexing plate 20 has three punching dies 40 arranged in a circular array, and each punching die 40 includes four placement slots 421 for placing four products connected together by the gate waste.

[0028] When the three punching dies 40 are located at the loading reserved station 11, the part to be punched taken out by the injection molding robot is placed on the punching die 40 (the product is located in the placement slot 421). When the three punching dies 40 are located at the punching station 12, the punching mechanism 30 set at the punching station 12 cuts off the gate waste of the part to be punched at the above-mentioned placement and removes it from the product in one go. When the three punching dies 40 are located at the unloading reserved station 13, the operator removes the punched products one by one and unloads them.

[0029] The punching mechanism 30 includes a frame 31 corresponding to the punching station 12 on the machine base 10, a punching power unit 32 on the top of the frame 31, a punching carrier plate 33 on the bottom of the frame 31 and connected to the punching power unit 32, four floating pressure blocks 34 on the bottom of the punching carrier plate 33, and four punching cutters 35 on the bottom of the punching carrier plate 33 corresponding to the four floating pressure blocks 34. When the indexing plate 20 rotates the punching die 40 to the point where the frame 31 descends, the punching power unit 32 drives the punching carrier plate 33 to descend. The four floating pressure blocks 34 first contact the product and press it down. As the punching carrier plate 33 continues to descend and the four floating pressure blocks 34 are compressed to the extreme, the four punching cutters 35 will cut the gate and the product off. In this way, the working efficiency is greatly improved and it has high application value.

[0030] The punching die 40 of this application includes a lower die plate 41 and four placement blocks 42 located above the lower die plate 41. Four placement slots 421 are respectively opened on the upper surface of the four placement blocks 42 and are respectively opened on opposite sides. The injection molding robot can place four products to be punched in the four placement slots 421 at the reserved loading position. In order to facilitate the easy discharge of the gate waste after punching, this application provides an outwardly inclined discharge ramp 43 on the lower die plate 41 corresponding to the middle of the four placement blocks 42. The surface of the discharge ramp 43 is a smooth marble surface. When the gate waste is punched, it will automatically fall into the marble surface, and under the action of inertia, the gate waste will automatically fall into the machine 10. In actual use, in order to facilitate the recycling of gate waste, the operator can set up a waste collection trough at the corresponding position for automatic recycling.

[0031] The punching power unit 32 of this application includes a punching cylinder 321. The punching cylinder 321 is located on the top of the frame 31 and its piston rod passes through the frame 31 and is connected to the punching carrier plate 33. Under the drive of the punching cylinder 321, the punching carrier plate 33 of this application will realize the lifting and lowering movement. In some preferred embodiments, the frame 31 of this application is provided with multiple guide sleeves inside, and multiple guide posts can be provided above the punching carrier plate 33 and pass through multiple guide sleeves. In this way, the punching carrier plate can achieve stable operation, thereby improving the punching quality.

[0032] In addition, for the installation of the floating pressure block 34 of this application, a thickening plate 36 is integrally provided at the bottom of the punching carrier plate 33. The thickening plate 36 has four guide grooves 37 extending to the punching carrier plate 33. The floating pressure block 34 includes a contour block 341 disposed in the guide groove 37, a guide rod 342 screwed into the guide groove 37 above the punching carrier plate 33 and connected to the contour block 341, and a compression spring 343 sleeved on the bottom of the punching carrier plate 33 outside the guide rod 342 and limited by the screw head of the guide rod 342. When the punching cylinder 321 drives the punching carrier plate 33 to descend, the contour block 341 first reaches the placement groove 421. When the cutting plate 33 continues to descend and contacts the product, the compression spring 343 will be compressed. When the compression spring 343 is compressed to its limit, the cutting tool 35 will cut off the gate waste. In order to make the contour block 341 closely cooperate with the guide groove 37, the present application provides grooves 371 on the inner walls of opposite sides of the guide groove 37. Protrusions 3411 are provided on opposite sides of the contour block 341 and inserted into the grooves 371. When the contour block 341 contacts the product and the cutting plate 33 continues to move downward, the protrusions of the contour block 341 will move up and down within the grooves 371 of the guide groove 37.

[0033] In a preferred embodiment, the punching tool 35 of this application has a beveled structure 351 on the side near the gate waste. When the punching tool 35 punches the gate waste, it can reduce the contact area with the gate waste, and can remove it more quickly, greatly improving work efficiency.
