Description

Technical Field

[0001] The utility model relates to the technical field of molds, in particular to a multifunctional waste unloading concave mold structure. Background Art

[0002] In modern manufacturing, the demand for high-efficiency and low-cost production has prompted mold design to continuously develop in the direction of integration, lightweight, and intelligence. However, traditional punching, shaping, and waste unloading processes often require multiple sets of molds or complex structures to achieve, which not only increases production costs, but also reduces part processing accuracy due to error superposition. In addition, the punches of traditional punching molds are all on the upper die seat and the concave holes are on the lower die seat. The punches quickly protrude from the concave holes to punch out the sheet material, causing the waste to fall into the concave holes. This method of punching and blanking from top to bottom not only makes the product prone to wrinkles and bends in the through-hole parts of the product, but also takes time and effort to clean the concave holes in the later stage, and safety is not guaranteed.

[0003] Therefore, the existing mold structure needs to be further improved and upgraded. Utility Model Content

[0031] The present embodiment provides a multifunctional waste unloading die structure, which is mainly used to solve the problems that the existing die structure needs to be divided into multiple sets of dies or complex structures when punching and shaping products, which increases production costs and has low processing accuracy. In addition, when the punching die is used to punch waste, the product is prone to wrinkles and the through-hole part of the product is prone to bending. It is time-consuming and laborious to clean the concave holes later, and the safety is not guaranteed. The die structure mainly includes a lower die base 1 and a punching die 21 in an upper die base; see Figures 1 to 5 ,in,

[0032] The lower die base 1 is provided with at least one shaping groove 11, which is arranged according to the number of shaping parts, and a punch 12 is fixedly arranged at the center of the shaping groove 11 according to the number of holes to be punched, so as to complete product shaping and punching at the same time.

[0033] The upper die seat is provided with a punching die 21 corresponding to the shaping groove 11. The punching die 21 has a storage cavity 22 with an opening facing the punch 12 at the center thereof. The opening is located at the lower end of the punching die 21. A mutually abutting ejector pin 23 and a rebound assembly are provided in the storage cavity 22. The punch 12 and the ejector pin 23 are coaxially arranged, that is, the two correspond to each other coaxially.

[0034] When the mold is working, the lower die seat 1 moves downward relative to the upper die seat, and the punching die 21 presses the material plate into the shaping groove 11 for shaping. At the same time, the punch 12 abuts against the ejector pin 23, driving the ejector pin 23 to act on the rebound component and slide in the storage cavity 22, and ejecting the waste material on the material plate into the storage cavity 22;

[0035] The lower die base 1 moves upward relative to the upper die base, the punch 12 and the ejector pin 23 are disengaged, and the ejector pin 23 is reset and moved toward the punch 12 under the action of the rebound component to discharge the waste out of the storage cavity 22, while completing the punching of holes, product shaping and later waste cleaning, with extremely high production efficiency.

[0036] In this embodiment, the upper die base is also slidably provided with a presser 25, and the presser 25 is elastically connected to the upper die base through a nitrogen spring 241 or an ordinary spring 241. Before the product is shaped and punched, the presser 25 will be pre-pressed around the entire material plate, and the punched waste part is also pressed by the punch 12 and the ejector pin 23. The two-side pressing method of pressing the material plate around and the waste part is also pressed can ensure that when the product is punched, there will be no wrinkles or bends around the hole of the material plate, the product quality can be guaranteed, and assembly errors can be avoided during the later assembly of the material plate.

[0037] In this embodiment, at the position of the storage cavity 22, the punching die 21 is provided with a limiting step 24, and the ejector pin 23 is inserted in the storage cavity 22. The ejector pin 23 can abut against the limiting step 24 to restrict the movement of the ejector pin 23 toward the punch 12, so that the ejector pin 23 will not directly separate from the storage cavity 22 from the limiting step 24 under the rebound action of the rebound assembly, so that the waste material and the ejector pin 23 are discharged out of the mold together.

[0038] In this embodiment, the upper end of the punching die 21 has an installation opening 211, which connects the storage cavity 22 and the opening at the lower end of the punching die 21; the ejector pin 23 and the rebound assembly are installed in the storage cavity 22 through the installation opening 211, and the ejector pin 23 can slide in and out of the opening under the action of the rebound assembly and the punch 12.

[0039] In this embodiment, the rebound assembly includes a spring 241 and a locking head 242. The spring 241 is a coil spring 241, which can be replaced by a cylinder. This embodiment mainly uses the spring 241, which has lower cost and is more convenient to assemble; the locking head 242 is mainly a nut structure, which is mainly used to screw with the internal thread at the mounting port 211 of the punching die 21. When the ejector pin 23 and the spring 241 are installed in the storage cavity 22, the locking head 242 is screwed to the mounting port 211 to stop and constrain the ejector pin 23 and the spring 241 in the storage cavity 22. When the ejector pin 23 acts on the spring 241, the spring 241 stops on the locking head 242 and elastically deforms, thereby providing support for the deformation of the spring 241 and allowing the spring 241 to be compressed and reset.

[0040] The working principle and use process of this utility model:

[0041] When processing molds, refer to Figures 1 to 4 ,

[0042] The upper die seat moves downward from the initial position relative to the lower die seat 1, and the punch 12 and the ejector pin 23 will first abut and cooperate to position and constrain the material plate; as the upper die seat continues to move downward, the ejector pin 23 gradually slides toward the inside of the material storage cavity 22 under the action of the punch 12, and before the ejector pin 23 enters the material storage cavity 22, the presser 25 will first press around the material plate (not shown); after that, the upper die seat continues to move downward, see Figure 5 The presser 25 elastically slides relative to the upper die seat under the action of the spring 241 to completely press the material sheet, and then the punch 12 drives the ejector pin 23 to eject the waste material of the material sheet into the storage cavity 22 for storage, and at the same time, the punching die 21 presses the material sheet into the shaping groove 11 for shaping, and the two processes are completed at the same time;

[0043] After the operation is completed, the upper die seat is controlled to move upward relative to the lower die seat 1, and the punch 12 and the ejector pin 23 gradually disengage from the match. The ejector pin 23 is reset and moved toward the direction of the punch 12 under the action of the rebound component to discharge the waste to the outside of the storage chamber 22, completing the waste unloading process. During the whole process, the waste will not be stuck in the storage chamber 22, and there is no need to maintain and clean the storage chamber 22. Finally, the operator or an industrial manipulator can clean up the waste on the lower die seat 1, which is very convenient. The utility model has a simple structure, is easy to implement and has low cost. The mold structure integrates punching, shaping and unloading processes at the same time, and can complete multiple processes in a set of molds at the same time. At the same time, the waste can be discharged from the mold, which can improve production efficiency, reduce manufacturing costs, and reduce maintenance work. When the mold of this scheme is in operation, it can simultaneously shape and punch the material plate according to the product shape requirements, and the waste material after punching can be automatically discharged into the storage cavity 22 for storage. After the shaping and punching processes are completed, the upper die seat moves upward, and the ejector pin 23 can automatically discharge the waste material in the storage cavity 22 to the lower die seat 1 under the action of the rebound component. It is very convenient to clean, has strong reliability and high processing efficiency.

[0044] The description of the above specification and embodiments is used to explain the protection scope of the utility model, but does not constitute a limitation on the protection scope of the utility model. Through the enlightenment of the utility model or the above embodiments, ordinary technicians in this field can obtain modifications, equivalent replacements or other improvements to the embodiments of the utility model or part of the technical features thereof through logical analysis, reasoning or limited experiments, which should be included in the protection scope of the utility model.
