Description

Technical Field

[0001] This utility model relates to the field of edge pressing mold technology, and in particular to an edge pressing mold that is easy to demold. Background Technology

[0002] A mold is a tool that shapes a blank into a part with a specific shape and size under the action of external force. It is widely used in blanking, die forging, cold heading, extrusion, powder metallurgy pressing, pressure casting, and compression molding or injection molding of engineering plastics, rubber, ceramics and other products. A mold has a specific contour or internal cavity shape. By using the contour shape with a cutting edge, the blank can be separated according to the contour shape (blanking). By using the internal cavity shape, the blank can obtain a corresponding three-dimensional shape. A mold generally consists of two parts: a moving mold and a fixed mold (or a punch and a die). The two can be separated and joined. When separated, the part is taken out. When joined, the blank is injected into the mold cavity for forming. Molds are precision tools with complex shapes. They withstand the expansion force of the blank and have high requirements for structural strength, rigidity, surface hardness, surface roughness and machining accuracy. The development level of mold production is one of the important indicators of the level of mechanical manufacturing.

[0003] Some boards require edge pressing during processing. After pressing, the contact between the processed board and the support base will be relatively tight. Workers need to use hand tools to guide the processed board from the top of the support base, which is not only time-consuming and laborious, but also makes it impossible to press the edge simultaneously during the material guiding process, resulting in a slow edge pressing rate.

[0019] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0020] Example 1

[0021] Reference Figures 1-3 This is the first embodiment of the present invention, which provides a pressing die for easy demolding. It includes a processing table 1, a sliding plate 2 at the upper end of the processing table 1, and two sets of material guiding components 3 at the upper end of the sliding plate 2. The material guiding components 3 include a support base 31 at the upper end of the sliding plate 2. A first sliding rod 32 is inserted into the bottom end of the inner cavity of the support base 31. Two sets of sliding sleeves 33 are symmetrically fitted on the outer wall of the first sliding rod 32. An adjusting rod 34 is provided at the upper end of the sliding sleeve 33. A connecting rod 35 is provided at the upper end of the adjusting rod 34. A material guiding rod 36 is provided at the upper end of the connecting rod 35. A material guiding groove 37 that cooperates with the material guiding rod 36 is opened at the upper end of the support base 31. A first spring 38 is provided at the ends of the two sets of sliding sleeves 33 that are far apart from each other. A second spring 39 is fitted through the outer wall of the support base 31 of the first sliding rod 32.

[0022] The first slide rod 32 is movably inserted into the lower end of the support base 31. The upper and lower ends of the adjusting rod 34 are respectively hinged to the connecting rod 35 and the sliding sleeve 33. The sliding sleeve 33 is fixedly sleeved on the outer wall of the first slide rod 32.

[0023] The first spring 38 is movably sleeved on the outer wall of the first slide rod 32. The two ends of the first spring 38 are fixedly connected to the slide sleeve 33 and the support seat 31, respectively. A disc is fixedly provided at the end of the first slide rod 32 away from the support seat 31. The second spring 39 is movably sleeved on the outer wall of the first slide rod 32. The two ends of the second spring 39 are fixedly connected to the outer wall of the processing table 1 and the disc, respectively. A plate is placed on the upper surface of the support seat 31.

[0024] A support rod 4 is fixedly installed on the upper end of the processing table 1. A support plate 5 is fixedly installed on the upper end of the support rod 4. A cylinder 6 is fixedly installed on the upper end of the support plate 5. An adjustment plate 7 is provided at the extended end of the cylinder 6. The two ends of the adjustment plate 7 are movably sleeved on the outer wall of the support rod 4. A pressure plate 8 is fixedly installed at the lower end of the adjustment plate 7. The pressure plate 8 is located on both sides of the upper end of the guide assembly 3.

[0025] The sheet material to be pressed is placed on the upper end of the support base 31. The cylinder 6 is activated to extend, causing the adjusting plate 7 to slide downwards along the outer wall of the support rod 4. The pressure plate 8 moves downwards. When the pressure plate 8 contacts the sheet material, it causes the sheet material to move downwards. The sheet material causes the guide rod 36 to slide downwards along the guide groove 37. The guide rod 36 causes the connecting rod 35 to move downwards. The connecting rod 35 causes the adjusting rod 34 to rotate downwards. Since the sliding sleeve 33 is fixedly sleeved on the outer wall of the first sliding rod 32 and hinged to the adjusting rod 34, the adjusting rod 34 causes the first sliding rod 32 to slide along the support base 31. One set of first springs 38 away from the second spring 39 is stretched, while the other set of first springs 38 closer to the second spring 39 is stretched. The plate is compressed, and the second spring 39 is stretched until the plate is placed on the upper surface of the support 31. The pressure plate 8 continues to move downward to press the plate placed on the upper surface of the support 31. After the pressing is completed, the cylinder 6 is activated to retract, and the pressure plate 8 moves upward to leave the plate. Under the opposing elastic force of the first spring 38 and the second spring 39, the first slide rod 32 slides into the inner cavity of the support 31. The first slide rod 32 drives the connecting rod 35 to move upward through the adjusting rod 34. The connecting rod 35 drives the guide rod 36 to slide upward along the guide groove 37. The guide rod 36 pulls the plate out from the upper end of the support 31. The plate does not need to be pulled out from the upper end of the support 31 by hand, which facilitates the quick removal of the plate.

[0026] Example 2

[0027] Reference Figure 1-3This is the second embodiment of the present utility model. The difference between this embodiment and the first embodiment is that: a fixing block 9 is fixedly provided at the lower end of the processing table 1, a motor 10 is fixedly provided on one side of the fixing block 9, and a ball screw 11 is provided at the output end of the motor 10. The ball screw 11 is rotatably inserted into the middle of the fixing block 9.

[0028] The outer wall of the ball screw 11 is fitted with a ball sleeve 12, and the upper end of the ball sleeve 12 is provided with a slider. The slider and the sliding plate 2 are fixedly connected. The upper end of the processing table 1 is provided with a groove that cooperates with the slider.

[0029] Before pressing the edge of the sheet material, the sheet material is placed on the upper end of the two sets of support seats 31. After the sheet material is pressed, the cylinder 6 is activated to retract, causing the pressure plate 8 to leave the sheet material. Then, the motor 10 is activated to drive the ball screw 11 to rotate along the middle of the fixed block 9. The ball screw 11 drives the ball sleeve 12 to move. The ball sleeve 12 moves along the slide groove opened at the upper end of the processing table 1 through the slider. The sliding plate 2 slides along the upper surface of the processing table 1 until the slider moves to the end of the slide groove and can no longer slide. At this time, the other set of support seats 31 moves to the lower end of the pressure plate 8, so that the operator can press the edge of the sheet material placed on the upper end of the support seat 31. At the same time, the support seat 31 that has completed the edge pressing operation moves to the other end, and the operator can take out the sheet material that has completed the edge pressing on the upper end of the support seat 31 and place the new sheet material on the support seat 31 for material preparation. Thus, the material feeding and edge pressing operation can be carried out at the same time, which speeds up the sheet material processing speed.
