Technical Field
[0001] This utility model relates to the field of rubber sheet mold technology, specifically a rubber sheet mold that facilitates the collection of hole waste. Background Technology
[0002] The core function of PCB molds is to achieve efficient, high-precision, and mass production of PCBs. The molds are equipped with holes that perfectly match the positioning holes and mounting holes on the PCBs. During the processing, this prevents processing errors or poor contact of test probes caused by deviations in PCB placement. There are various types of PCB molds on the market that facilitate the collection of hole waste. However, conventional plastic sheet molds are not convenient for collecting the waste holes generated after die-cutting. As a result, when there is a lot of waste holes, it can affect the smoothness of the operation of the plastic sheet mold and make it difficult to automatically perform die-cutting. When the plastic sheet mold needs to be die-cut, manual mold closing may cause the plastic sheet mold to shift. It is also inconvenient to disassemble the die-cutting cutter. As a result, when the cutter is used frequently, it is easy for the cutter to wear out and become irreplaceable, affecting the die-cutting effect. Therefore, this utility model provides a plastic sheet mold that facilitates the collection of waste holes to solve the above-mentioned problems. Utility Model Content
[0003] The purpose of this utility model is to provide a plastic sheet mold that facilitates the collection of hole waste, thereby solving the problem mentioned in the background art that general plastic sheet molds are not convenient for collecting hole waste generated after die cutting. As a result, when there is a lot of hole waste, it is easy to affect the smoothness of the operation of the plastic sheet mold, making it difficult to automatically perform die cutting. When the plastic sheet mold needs to be die cut, manual mold closing may cause the plastic sheet mold to shift. It is also inconvenient to disassemble the die cutting cutter. As a result, when the cutter is used frequently, it is easy for the cutter to wear out severely and become irreplaceable, affecting the die cutting effect.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a rubber sheet mold for convenient collection of hole waste, comprising: The lower mold has a telescopic rod installed inside it. Also includes: The upper mold is fixedly connected to the upper side of the telescopic rod, and a fixed column is fixedly connected to the lower end of the upper mold. A first spring is fixedly connected to the inner side of the lower end of the fixed column. The perforated plate is fixedly connected to the lower side of the upper mold, and a waste collection structure is provided on the outer side of the perforated plate. The collection structure includes a collection plate, a threaded rod and a threaded sleeve. The collection plate is connected to the inner side of the perforated plate through a slot, and the threaded rod is connected to the inner slots at both ends of the collection plate. The threaded rod is threadedly connected to the outer side of the threaded sleeve. The inner end of the perforated plate is provided with a plate for disassembling the cutter.

[0008] Preferably, a grooved plate is fixedly connected to the lower end of the upper mold, and a splicing plate is slidably connected to the outer side of the grooved plate, with a cutter body installed at the lower end of the splicing plate.
[0009] Preferably, the lower end of the insert plate has a slot connected to a fixing rod, and the upper end of the insert plate is slidably connected to the outside of the rotating column. The upper rear end of the insert plate is fixedly connected to a second spring, and the front side of the second spring is fixedly connected to the rotating column. The rear end of the rotating column is rotatably connected to the upper mold.
[0010] Compared with the prior art, the beneficial effects of this utility model are: the PCB mold that facilitates the collection of hole waste can ensure that the PCBs placed on the front and back sides of the middle of the mold can be fixed in the same preset position every time, ensuring that there is no deviation in the mold operation, preventing the accumulation of hole waste, which would affect the processing and positioning operation of the PCB mold, and avoiding severe wear of the cutter, which would affect the processing effect. 1. It is equipped with a lower mold, a telescopic rod and an upper mold. The telescopic rod drives the upper mold, which is fixedly connected to the upper end of the telescopic rod, to move up or down. This causes the fixed column, which is fixedly connected to the lower end of the upper mold, to slide up or down inside the lower mold. This allows the positioning column body, which is fixedly connected to the upper end of the lower mold, to continuously connect with the slot inside the perforated plate, thus enabling automatic mold closing operation of the rubber plate mold. 2. It is equipped with a lower mold, a fixed column and a first spring. The first spring is fixedly connected to the lower end of the lower mold and the lower end of the first spring is fixedly connected to the inner side of the lower end of the fixed column. When the upper mold moves, the first spring is subjected to pressure and deforms, which can increase the mold closing stability of the rubber plate mold. 3. It is equipped with an orifice plate, a collection plate and a threaded rod. By pushing the collection plate inward, the front and rear sides of the collection plate are connected to the threaded rod through the slots, and a threaded sleeve is threaded to the outside of the threaded rod. The inner end of the threaded sleeve is tightly fitted to the collection plate, which limits the collection plate and prevents the collection of waste from the orifice. 4. It is equipped with an upper mold, a groove plate and a splicing plate. By fixing the groove plate to the lower end of the upper mold, the splicing plate is pushed backward, so that the inside of the splicing plate slides backward on the outside of the groove plate. The paper splicing plate is completely connected to the groove plate. At this time, the cutter body array installed at the lower end of the splicing plate forms a stable cutter positioning effect. 5. Equipped with a fixed rod, insert plate, and rotating column, pushing the insert plate forward causes the second spring fixedly connected to the front end of the insert plate to be compressed and deformed, and the rotating column rotates, causing the insert plate to flip in different directions and pull the splicing plate forward to disassemble the splicing plate, which can avoid the situation where the cutter is severely worn and cannot be replaced.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0014] Please see Figures 1-5 This utility model provides a technical solution: a rubber plate mold for convenient collection of hole waste, including a lower mold 1, a telescopic rod 2, an upper mold 3, a fixed column 4, a first spring 5, a positioning column body 6, a hole plate 7, a collection plate 8, a threaded rod 9, a threaded sleeve 10, a groove plate 11, a splicing plate 12, a cutter body 13, a fixed rod 14, an insert plate 15, a rotating column 16, and a second spring 17; Existing plastic sheet molds are not convenient for collecting the hole waste generated after die cutting. When there is a lot of hole waste, it can easily affect the smoothness of the operation of the plastic sheet mold and make it difficult to perform automatic die cutting. When the plastic sheet mold needs to be die cut, manual mold closing may cause the plastic sheet mold to shift. It is also inconvenient to disassemble the die cutting cutter. When the cutter is used frequently, it is easy for the cutter to wear out severely and become irreplaceable, which affects the die cutting effect. The lower mold 1 is equipped with a telescopic rod 2, and the upper mold 3 is fixedly connected to the upper end of the telescopic rod 2. The lower end of the upper mold 3 is fixedly connected to a fixing post 4. The lower inner side of the fixing post 4 is fixedly connected to a first spring 5, and the upper end of the first spring 5 is fixedly connected to the lower mold 1. The fixing post 4 is slidably connected inside the lower mold 1. The upper left and right sides of the lower mold 1 are provided with positioning post bodies 6, and the upper side of the positioning post body 6 is connected to a perforated plate 7 through a slot. The upper end of the perforated plate 7 is fixedly connected to the upper mold 3.
[0015] When the PCB molds need to be merged, the telescopic rod 2 is activated, causing it to retract inward and move the fixed column 4, which is fixedly connected to the upper end of the telescopic rod 2, downward. At this time, the fixed column 4, which is fixedly connected to the lower end of the upper mold 3, moves downward. The first spring 5, which is fixedly connected to the inner side of the lower end of the fixed column 4, is under pressure and deforms, causing the fixed column 4 to slide downward inside the lower mold 1 until the perforated plates 7, which are fixedly connected to the left and right sides of the upper mold 3, move downward until the positioning holes inside the perforated plates 7 are connected to the positioning column body 6. This ensures that the PCBs placed on the front and rear sides of the middle of the mold can be fixed in the exact same preset position each time, ensuring that there is no deviation in the mold operation.
[0016] The lower end of the upper mold 3 is fixedly connected to the perforated plate 7, and the internal slot of the perforated plate 7 is connected to the collecting plate 8. The front and rear slots of the collecting plate 8 are connected to the threaded rods 9. The outer side of the threaded rods 9 is threadedly connected to the threaded sleeves 10, and the inner end of the threaded sleeves 10 is tightly fitted to the collecting plate 8.
[0017] When it is necessary to collect the hole waste from the positioning holes of the rubber sheet mold, after the positioning pin body 6 and the positioning plate 7 have been matched many times, a lot of hole waste is generated. This waste falls into the inside of the collection plate 8. Rotating the threaded sleeve 10 outward causes the inside of the threaded sleeve 10 to disengage from the threaded connection with the threaded rod 9. Pulling the collection plate 8 outward causes the upper side of the collection plate 8 to disengage from the slot connection with the hole plate 7. At the same time, the inner sides of the front and rear ends of the collection plate 8 slide outward on the outside of the threaded rod 9 until the threaded rod 9 and the collection plate 8 disengage from the slot connection. The hole waste collected inside the collection plate 8 is then cleaned. At the same time, the remaining hole waste inside the hole plate 7 is also cleaned to prevent the hole waste from accumulating and affecting the processing and positioning operation of the rubber sheet mold.
[0018] The lower end of the upper mold 3 is fixedly connected to a groove plate 11, and the outer side of the groove plate 11 is slidably connected to a splicing plate 12. The front end of the groove plate 11 is fixedly connected to a fixing rod 14, and the outer side of the fixing rod 14 is connected to an insert plate 15. The upper end of the insert plate 15 is slidably connected to the outer side of the rotating column 16, and the rear end of the rotating column 16 is rotatably connected to the front end of the upper mold 3. The front end of the insert plate 15 is fixedly connected to a second spring 17, and the front end of the second spring 17 is fixedly connected to the rotating column 16. The lower end of the splicing plate 12 is equipped with a cutter body 13.
[0019] When the die-cutting cutter needs to be replaced, push the insert plate 15 forward, so that the second spring 17 fixedly connected to the upper front end of the insert plate 15 is under pressure and deformed, so that the interior of the rear end of the insert plate 15 disengages from the slot connection between it and the fixing rod 14. Then rotate the rotating column 16 to flip the insert plate 15 to the opposite end, and pull the splicing plate 12 forward, so that the interior of the splicing plate 12 slides forward on the outside of the groove plate 11 until the interior of the splicing plate 12 disengages from the slot connection between it and the groove plate 11. At the same time, the cutter body 13 installed at the lower end of the splicing plate 12 moves, which can prevent the cutter from being severely worn and damaged, thus affecting the processing effect.
