Technical Field

[0001] This utility model relates to the field of mold technology, and in particular to a mold with a pressure sleeve. Background Technology

[0002] With the continuous development of the electronics industry, the market demand for metal drawing and stamping parts has increased significantly, and the requirements for product precision, production efficiency, and stability are rising. This has directly driven the mold industry to explore efficient and reliable drawing technologies. In the production of metal products, thin material (such as 0.3mm thick) drawing is a common process, and some complex products require two drawing processes to complete the drawing process.

[0003] In existing stretching die technology, when the product after the first stretching process enters the second stretching process, the lack of material fixation and constraint makes it prone to positioning misalignment and accumulation. This leads to quality problems such as wrinkling and tearing, affecting product yield and increasing the risk of customer complaints. Furthermore, material accumulation and product damage frequently cause die failures, requiring downtime for repairs, significantly reducing production time and resulting in low production efficiency. This makes it difficult to meet the demands of modern intelligent manufacturing for rapid response, high reliability, and automated integration. Utility Model Content

[0021] like Figures 1-4As shown, the present invention proposes a mold with a pressure sleeve, comprising an upper mold assembly 101 and a lower mold assembly 102, wherein both the upper mold assembly 101 and the lower mold assembly 102 are mounted on a stamping forming machine and move relative to each other in a vertical direction under the drive of the stamping forming machine; it also includes: One end of the stretching man 200 is inserted into the upper module 101, and during the movement of the upper module 101, it drives the stretching man 200 to move simultaneously. The pressure sleeve 300 is fitted onto one end of the stretching man 200 and moves vertically along with the stretching man 200 under the action of the upper module 101. When the upper module 101 moves to the position of the lower module 102, the stretching man 200 drives the pressure sleeve 300 into the product 700 to position and press the product 700. When the upper module 101 moves away from the lower module 102, the stretching man 200 causes the pressure sleeve 300 to separate from the product 700. Several push rods 400 have one end respectively... The upper module 101 is fitted with a push rod 400, with one end contacting the pressure sleeve 300. The pressure sleeve 300 is limited by a push rod 400. Specifically, one end of the push rod 400 is embedded in the upper module 101, and the other end limits the pressure sleeve 300 during use to prevent excessive movement of the pressure sleeve 300. The die structure 500 is set on the lower module 102 and is positioned opposite to the pressure sleeve 300. The product 700 is placed through the die structure 500, and the product 700 is stretched a second time in conjunction with the stretching rod 200 and the pressure sleeve 300. In this utility model, preferably, three push rods 400 are provided, evenly spaced on the upper module 101. In actual use, product 700 is placed on die structure 500. The upper die assembly 101, driven by the stamping machine, moves the drawing man 200 and pressure sleeve 300 towards the position of product 700. As the upper die assembly 101 gradually approaches the lower die assembly 102, the pressure sleeve 300 inserts into product 700 and continues to penetrate until it contacts the bottom of the product 700, completing the positioning and clamping of product 700. As the upper die assembly 101 continues to move, it also drives the drawing man 200 to press against the pressure sleeve... The internal action, after contacting the bottom of product 700, performs a secondary stretch on product 700; while the stretching manifold 200 is performing a secondary stretch on product 700, several push rods 400 contact the pressure sleeve 300, which on the one hand presses the pressure sleeve 300 and restricts the position of the pressure sleeve 300, and on the other hand prevents the stretching manifold 200 from excessively stretching product 700; after the secondary stretch is completed, the upper mold 101 is reversed under the drive of the molding machine, separating the pressure sleeve 300 from product 700, thus completing the secondary stretch of product 700.

[0022] The technical solution of this utility model adds a pressure sleeve 300 in the second process, which can stably press the product 700 before stretching, effectively avoiding problems such as wrinkling and tearing caused by material positioning misalignment and accumulation during the stretching of thin materials (0.3mm). The pressure sleeve 300 is fitted inside the stretching manifold 200, which can not only ensure that the stretching manifold 200 can smoothly guide the product 700, but also form a stable constraint on the material, so that the stretching quality of the product 700 meets the control standards, and significantly reduce customer complaints caused by quality problems.

[0023] like Figure 2 and Figure 3 As shown, the die structure 500 includes a die pad 501 disposed within the lower die assembly 102; a die module 502 disposed within the lower die assembly 102 and mounted on the die pad 501; and a pusher 503 disposed within the lower die assembly 102, with one end passing through the die pad 501 and positioned within the die module 502. The die pad 501 engages with the interior of the lower die assembly 102, supporting the die module 502 and ensuring its stability during use. Furthermore, the pusher 503 can be adjusted within the lower die assembly 102, thereby changing the position of one end within the die module 502 to accommodate the secondary stretching of different products 700. A stretching space 504 is formed between one end of the pusher 503 and the inner surface of the die module 502. By adjusting the vertical position of the pusher 503, the size of the stretching space 504 is changed, thus better adapting to the secondary stretching of different products 700.

[0024] Additionally, the stretching man 200 includes a stretching rod 201 and a stretching head 202 disposed on the stretching rod 201; one end of the stretching rod 201 passes through the upper module 101, and the stretching head 202 is disposed at the other end of the stretching rod 201; during the operation phase, the stretching head 202 can limit the pressure sleeve 300 to prevent the pressure sleeve 300 from detaching from the stretching man 200; specifically, the pressure sleeve 300 is provided with a sleeve interface 301, through which the pressure sleeve 300 is disposed on the stretching rod 201; during secondary stretching... The tension rod 201 can slide within the sleeve interface 301 to perform secondary stretching on the product 700. After the secondary stretching is completed, the tension rod 201 is moved by the upper module 101. Since the diameter of the tension head 202 is larger than the diameter of the sleeve interface 301, the movement of the tension rod 201 can drive the pressure sleeve 300 to move simultaneously with the tension rod 201, and the pressure sleeve 300 is pulled away from the product 700 by the tension head 202. In this utility model, the tension rod 201 and the tension head 202 are preferably integrally formed.

[0025] like Figure 4As shown, the outer diameter of the pressure sleeve 300 is smaller than the inner diameter of the product 700. Specifically, the outer diameter of the pressure sleeve 300 is 0.1mm smaller than the inner diameter of the product 700. This gap ensures that the pressure sleeve 300 can be smoothly inserted into the product 700, while also preventing the product positioning from shifting due to an excessively large gap. The diameter of the sleeve interface 301 is larger than the diameter of the tension rod 201, and the inner diameter of the pressure sleeve 300 is larger than the diameter of the tension head 202. This creates a gap of 0.02mm between the tension rod 201 and the tension head 202 and the pressure sleeve 300, which reduces the sliding friction between the tension rod 201 and the pressure sleeve 300, prevents material jamming, and ensures the guiding accuracy of the tension rod 201.

[0026] like Figure 1 As shown, the upper module 101 is provided with a plurality of guide posts 601; the other ends of the guide posts 601 are inserted into a plurality of guide sleeves 602 on the lower module 102; during the operation of the upper module 101, the movement direction of the upper module 101 is restricted by the cooperation of the guide posts 601 to ensure the stability of the movement trajectory of the tensioning man 200; preferably, four guide posts 601 are provided at the four corners of the upper module 101 and four guide sleeves 602 are provided at the four corners of the lower module 102; the movement trajectory of the upper module 101 is ensured by the cooperation of the guide posts 601 and the guide sleeves 602.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
