[0041] The present invention provides a cup-shaped antenna vibrator forming mold. To make the purpose, technical solution, and effects of the present invention more clear and explicit, the present invention is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific examples described herein are only intended to illustrate the present invention and are not intended to limit the present invention.

In addition, "first" and "second" are only for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0043] See also Figures 1 to 6 As shown, the utility model provides a cup-shaped antenna vibrator forming mold, which includes: an upper pressing plate 1 and a lower base plate 2, the upper pressing plate 1 can move away from or closer to the lower base plate 2, and a first cutting component 3, a stamping component 4 and a second cutting component 5 are sequentially arranged between the upper pressing plate 1 and the lower base plate 2. The first cutting component 3 is arranged at the loading end and is used to cut the raw material into a shape suitable for stamping. The stamping component 4 includes a plurality of stamping stations, and the plurality of stamping stations perform advanced stamping and forming on the raw material cut by the first cutting component 3 in steps. The second cutting component 5 is arranged at the unloading end and is used to cut the antenna vibrator stamped and formed by the stamping component 4 from the waste material. In this embodiment, the upper pressing plate 1 and the lower base plate 2 are both installed on the stamping equipment. In order to facilitate the automatic loading device of the stamping equipment to accurately transport the raw materials to various positions, the lower base plate 2 is stationary, and the upper pressing plate 1 is intermittently pressed down close to the lower base plate 2 to drive each component to work. Multiple stamping stations perform advanced stamping on raw materials in steps, which can reduce unnecessary stress concentration and crack generation, avoid problems such as brittle fracture and tensile deformation of materials, and improve the accuracy and toughness of the finished product.

[0044] During the actual stamping process, the sheet metal raw material strip is transported to the first cutting component 3 through a step-by-step automatic loading device for the first cutting, cutting out the shape required for stamping. However, the stamping part material is not completely cut off from the metal raw material strip, so that this stamping part material can be continuously transported to the subsequent stamping component 4 for step-by-step advanced stamping and forming. The stamped finished product is transported to the second cutting component 5 for a second cutting, so that the finished product is sheared and separated from the excess material, and the remaining waste material is cut off from the metal raw material strip to achieve automatic blanking. The first cutting component 3, stamping component 4 and second cutting component 5 of the cup-shaped antenna vibrator forming mold work synchronously. A finished product can be obtained each time the upper pressure plate 1 and the lower base plate 2 are opened and closed. The entire process is automated, and there is no need for manual loading and unloading, which improves production efficiency and product quality.

[0045] See also Figure 1 As shown, the upper pressing plate 1 is provided with at least two guide sleeves 11, and the lower base plate 2 is provided with at least two first guide posts 21. The first guide posts 21 are sequentially sleeved with first springs 22 and guide bearings 23 from bottom to top. The at least two guide sleeves 11 are provided in a one-to-one correspondence with the at least two first guide posts 21. When the upper pressing plate 1 moves closer to the lower base plate 2, the guide sleeves 11 are sleeved on the outside of the guide bearings 23. In this embodiment, the number of guide sleeves 11 and first guide posts 21 is four. The four guide sleeves 11 are respectively located at the four corners of the upper pressing plate 1, and the four first guide posts 21 are respectively located at the four corners of the lower base plate 2. The number of first springs 22 and guide bearings 23 matches the number of first guide posts 21. The guide bearings 23 are linear bearings that reduce friction between the first guide posts 21 and the guide sleeves 11. The first springs 22 are used to lift and reset the guide bearings 23 that are pressed down by the guide sleeves 11. The cooperation between the first guide post 21 and the guide sleeve 11 makes the upper pressing plate 1 move more smoothly relative to the lower base plate 2, thereby ensuring the working accuracy of the first cutting assembly 3, the punching assembly 4 and the second cutting assembly 5, and ensuring the production quality of the finished product.

[0046] See also Figures 1 to 4 As shown, the first cutting assembly 3 includes a first cutting pressure plate 31 mounted on the lower base plate 2, a plurality of second guide pillars 32, a plurality of second springs 33 and two first cutters 34. The first cutting pressure plate 31 is movably connected to the upper pressure plate 1 via the plurality of second guide pillars 32. One end of the second guide pillar 32 is fixedly connected to the upper pressure plate 1, and the other end of the second guide pillar 32 is movably connected to the first cutting pressure plate 31. A plurality of second springs 33 are arranged between the upper pressure plate 1 and the first cutting pressure plate 31. The two first cutters 34 are fixedly connected to the upper pressure plate 1 in sequence along the conveying direction of the raw materials. Each first cutter 34 includes two arc-shaped blades symmetrically arranged with the center of the circle. The distance between the two blades of the two first cutters 34 is not the same, and the connecting line between the two blades of the two first cutters 34 is perpendicular to each other. In this embodiment, there are four second guide posts 32, which are respectively located at the four corners of the first cutting plate 31. There are at least four second springs 33, and the two ends of the second springs 33 are respectively fixedly connected to the upper plate 1 and the first cutting plate 31. The first cutting plate 31 is provided with two through holes for two first cutters 34 to pass through respectively. The distance between the lower bottom surface of the first cutting plate 31 and the lower bottom surface of the lower plate is greater than or equal to the length of the first cutter 34, so that when the upper plate 1 is away from the lower bottom plate 2, the blade of the first cutter 34 will not be exposed outside the first cutting plate 31, thereby protecting the first cutter 34. The blades of the two first cutters 34 are placed in different positions and have different diameters, so that a connecting belt can be formed between the stamped part of the material and the metal raw material strip after the stamping deformation, so as to achieve continuous material transportation while facilitating movement and positioning.

[0047] See also Figure 3 As shown, the first cutting assembly 3 further includes a first cutting base 35, which is provided with two cutting grooves 351 and a plurality of first clearance grooves 352.

The plurality of first clearance grooves 352 are provided to correspond to the plurality of second guide posts 32 and are used to accommodate the second guide posts 32. In this embodiment, the number of first clearance grooves 352 matches the number of second guide posts 32. The depth of the first clearance grooves 352 is greater than the thickness of the metal stock strip. When the second guide posts 32 enter the first clearance grooves 352, the first cutting pressure plate 31 is pressed against the first cutting base 35, compressing the second spring 33, thereby allowing the blade of the first cutter 34 to pass through the through hole and punch the metal stock strip. The depth of the cutting grooves 351 is close to the thickness of the metal stock strip, allowing the first cutter 34 to cut through the metal stock strip without being too deep to cause material deformation.

[0048] When the upper platen 1 moves downward toward the lower base plate 2, the first cutting platen 31 first contacts the metal strip being conveyed to the first cutting base plate 35. As the upper platen 1 continues to press downward, the first cutting platen 31 is blocked by the first cutting base plate 35 and cannot continue to press downward. The end of the second guide post 32 extends into the first clearance groove 352, and the second spring 33 is squeezed and deformed. The first cutter 34 extends from the through hole and presses down into the cutting groove 351. The two first cutters 34 successively cooperate to cut the metal strip into the shape required for stamping. Each time the upper platen 1 is pressed downward, the two first cutters 34 perform a punching action simultaneously. The first first cutter 34 only cuts half of the material, and the second first cutter 34 cuts the remaining half of the material, forming a streamlined operation and improving efficiency.

The inner diameter of the blanking channel 534 is slightly larger than the outer diameter of the four third cutters 535. The blades of the third cutters 535 and the inner edges of the upper ends of the blanking channel 534 form a scissors-like structure to cut the portion between the semi-finished product and the remaining material that has not been cut by the second cutters 515. There are four fifth guide posts 522 and four fifth springs 523 corresponding to the second movable cutting plate 533. The four fifth guide posts 522 are located at the four corners of the second movable cutting plate 533, and the four fifth springs 523 are located next to the four fifth guide posts 522. Blanking holes are provided on the lower pressing plate at positions corresponding to the blanking channel 534. The blanking holes are used to connect the fourth through hole 537 with a designated collection container for collecting the sheared finished products.

[0054] When the upper pressure plate 1 is pressed down and approaches the lower base plate 2, the fifth cavity part 531 is pressed down so that the stamped semi-finished product enters the cavity and is located between the four third cutters 535. The second cutting movable plate 533 is squeezed downward by the fifth cavity part 531, and the upper end of the blanking channel 534 extends from the third through hole 536 and enters the gap between the inner wall of the cavity of the fifth cavity part 531 and the third cutter 535, cutting the semi-finished product from the residual material to obtain the finished product, and the finished product will fall from the blanking channel 534 into the collection container.

[0055] See also Figures 1 to 2As shown, the second cutting assembly 5 further includes a fourth cutter 538, which is disposed on a side of the fifth cavity member 531 away from the fourth cavity member 511. The blade of the fourth cutter 538 is lower than the lower edge of the fifth cavity member 531. When the fifth cavity member 531 is pressed against the second cutting movable plate 533, the fourth cutter 538 can cut off the waste material hanging outside the mold, preventing the waste material from being too long and hitting other items, thereby affecting the conveying of the material being stamped and cut later, thereby affecting production accuracy and quality.

[0056] To sum up, the utility model uses automatic loading equipment to transport raw materials to the position of the first cutting component 3 for cutting into the shape required for stamping. The raw materials cut into the stamping shape are sent to the stamping component 4 for step-by-step stamping. The stamped cup-shaped antenna vibrator reaches the second cutting component 5 for cutting. The cup-shaped antenna vibrator is cut and separated from the waste material. When the upper pressure plate 1 is close to the lower base plate 2, the above process is carried out simultaneously. There is no need for manual loading and unloading, the degree of automation is high, and the production efficiency is improved.

[0057] It is understandable that those skilled in the art can make equivalent substitutions or changes based on the technical solution and utility model concept of the present invention, and all these changes or substitutions should fall within the scope of protection of the claims attached to the present invention.
