Description

Technical Field

[0001] The utility model belongs to the technical field of molds, in particular to an O-type sealing ring processing mold. Background Art

[0002] O-ring is a circular sealing ring, which is one of the common sealing mechanical designs. It has the advantages of low price and simple production.

[0003] During the use of the existing O-ring, the O-ring is usually placed on the position where sealing is required, so that the designated position can be sealed. The O-ring has strong sealing performance and simple structure, so it provides important protection for industrial production and daily life.

[0004] It has been found through long-term use and observation that the existing O-ring processing molds require high-intensity extrusion of the raw materials during the extrusion molding process of the O-rings, so that the raw materials are turned into O-rings. Under high-intensity extrusion, the discarded raw materials will fit tightly with the molding plate, resulting in the raw material plate being difficult to clean after the sealing ring is processed and molded.

[0005] To this end, the utility model provides an O-type sealing ring processing mold. Utility Model Content

Through the above structure, a plurality of raw material plates can be extruded and formed at the same time, and a plurality of groups of sealing rings can be formed at the same time, and the sizes of the sealing rings after the multiple groups are formed are the same, which reduces the situation in which the position of the raw material plates is offset during batch forming, resulting in different sizes of the sealing rings formed. At the same time, by placing the raw material plates inside the placement groove, the processed raw material plates can be more conveniently recycled and processed again, which reduces the situation in which the waste materials are difficult to collect uniformly after the sealing rings are formed.

[0008] Preferably, two card slots are provided at the bottom of the placement plate at the bottom; the two card slots are symmetrically arranged; a card block is detachably installed inside the card slot; a collection box is fixedly connected to the bottom of the card block; the collection box faces multiple groups of discharge holes. Through the above structure, the formed sealing rings can be uniformly collected and processed, reducing the situation where a large number of formed sealing rings make it difficult to collect them uniformly, and at the same time reducing the situation where the formed sealing rings fall to other locations, causing waste of raw materials.

[0009] Preferably, an extrusion sheet is slidably connected to the inside of the forming hole; a plurality of groups of second through holes are opened on the top of the support plate; the plurality of second through holes all penetrate the extrusion cylinder; a plurality of groups of second electric telescopic rods are fixedly connected to the top of the plurality of extrusion sheets; a plurality of groups of second electric telescopic rods penetrate the second through holes and extend to the top of the support plate; a top plate is fixedly connected to the top of the plurality of second electric telescopic rods. Through the above structure, the sealing ring stuck in the forming hole can be pushed out of the forming hole, thereby reducing the situation where the sealing ring is stuck in the forming hole and causes blockage of the forming hole, thereby reducing the situation where the blockage of the forming hole affects the subsequent processing of the sealing ring.

[0010] Preferably, a connecting rod is connected in the middle of the two first electric telescopic rods; the connecting rod is located at the output end of the first electric telescopic rod. Through the above structure, the movement trajectories of the two first electric telescopic rods can be made the same, thereby reducing the situation in which the sealing ring processing is asynchronous due to the different movement trajectories of multiple extrusion cylinders.

[0011] Preferably, two push rods are directly installed on the opposite surfaces of the multiple groups of placement plates; the two push rods are symmetrically arranged. Through the above structure, the situation in which the raw material plate is difficult to place inside the placement groove due to the multiple placement plates being too closely fitted can be reduced.

[0012] Preferably, a baffle is fixedly connected to the bottom of the top plate; the bottom of the baffle is fixedly connected to the top of the support plate. Through the above structure, the multiple groups of second electric telescopic rods can be protected, thereby reducing the situation in which the multiple groups of second electric telescopic rods are affected by external dust or impurities during work, thereby causing damage to the second electric telescopic rods.

DETAILED DESCRIPTION

[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0024] like Figures 1 to 5As shown, an O-ring processing mold described in an embodiment of the utility model includes a support plate 1; a plurality of extrusion cylinders 12 are fixedly connected to the bottom of the support plate 1; the plurality of extrusion cylinders 12 are equidistantly distributed at the bottom of the support plate 1; a plurality of molding holes 13 are provided at the bottom of the plurality of extrusion cylinders 12; two first electric telescopic rods 14 are fixedly connected to the bottom of the support plate 1; the two first electric telescopic rods 14 are symmetrically arranged and located near the two ends of the support plate 1; a plurality of placement plates 15 are provided in the middle of the first electric telescopic rod 14; two first through holes 17 are provided in the middle of the plurality of placement plates 15; the two first through holes 17 are Symmetrical arrangement; the middle of the first electric telescopic rod 14 passes through the first through hole 17 to connect the multiple placement plates 15; the tops of the multiple placement plates 15 are provided with placement grooves 18; the interior of the placement grooves 18 is provided with multiple discharge holes 16; the multiple discharge holes 16 are evenly distributed inside the placement grooves 18, and correspond to the positions of the multiple extrusion cylinders 12. When working, the multiple placement plates 15 are installed to the middle of the first electric telescopic rod 14. At this time, as the multiple placement plates 15 are installed to the specified positions, the multiple discharge holes 16 also correspond to the positions of the multiple extrusion cylinders 12. At this time, by placing the raw materials of the sealing ring in batches inside the placement grooves 18, At this time, the raw material of the sealing ring blocks the multiple discharge holes 16. At this time, by starting the first electric telescopic rods 14 on both sides, as the first electric telescopic rods 14 are started, the output ends of the first electric telescopic rods 14 will telescope back and forth. At this time, when the first electric telescopic rods 14 are started, the extrusion cylinder 12 will gradually approach the inside of the discharge hole 16, and at the same time approach the raw material of the sealing ring until it fits with the raw material. At this time, the first electric telescopic rod 14 is continued to be started. As the first electric telescopic rod 14 continues to move, multiple extrusion cylinders 12 simultaneously penetrate multiple discharge holes 16 and extend to the bottom. At this time, multiple extrusion cylinders 12 simultaneously penetrate the raw material of the sealing ring. At this time, the positions corresponding to the raw materials and the discharge holes 16 will be cut by multiple extrusion cylinders 12, and at this time, the O-shaped sealing ring will enter the interior of the forming hole 13. Through the above structure, multiple raw material plates can be extruded and formed at the same time, and multiple groups of sealing rings can be formed at the same time, and the sizes of the sealing rings after multiple groups are the same, which reduces the situation in which the position of the raw material plates is offset during batch forming, resulting in different sizes of the sealing rings. At the same time, by placing the raw material plates inside the placement groove 18, the processed raw material plates can be more conveniently recycled and processed again, which reduces the situation in which the waste materials are difficult to collect uniformly after the sealing rings are formed.

[0025] like Figure 5As shown, two card slots 2 are provided at the bottom of the placement plate 15 at the bottom; the two card slots 2 are symmetrically arranged; a card block 21 is detachably installed inside the card slot 2; a collection box 22 is fixedly connected to the bottom of the card block 21; the collection box 22 is opposite to the multiple groups of discharge holes 16. When working, the card block 21 is buckled into the inside of the card slot 2. At this time, as the card block 21 is installed, the collection box 22 will also be in a corresponding position, that is, corresponding to the position of the multiple discharge holes 16. At this time, by starting the first electric telescopic rod 14, the extrusion cylinder 12 extrude the raw material plate, so that the sealing ring is formed. At this time, the formed sealing ring will fall off from the inside of the forming hole 13, and then fall into the inside of the collection box 22. Through the above structure, the formed sealing rings can be uniformly collected and processed, reducing the situation where there are too many formed sealing rings and it is difficult to collect them uniformly. At the same time, it reduces the situation where the formed sealing rings fall to other positions and cause waste of raw materials.

[0026] like Figure 2 and Figure 3 As shown, the inside of the forming hole 13 is slidably connected with an extrusion sheet 3; a plurality of groups of second through holes 33 are provided on the top of the support plate 1; a plurality of groups of the second through holes 33 all penetrate the extrusion cylinder 12; a plurality of groups of the extrusion sheets 3 are fixedly connected to the top with a plurality of groups of second electric telescopic rods 31; a plurality of groups of the second electric telescopic rods 31 penetrate the second through holes 33 and extend to the top of the support plate 1; a plurality of groups of the second electric telescopic rods 31 are fixedly connected to the top with a top plate 32. During operation, after the extrusion cylinder 12 extrude and mold the raw material plate, the sealing ring will enter the inside of the forming hole 13. Due to gravity, a part of the sealing ring will directly fall into the inside of the collection box 22. At the same time, a part of the sealing ring will be stuck in the inside of the forming hole 13 and will be difficult to fall off, thereby causing blockage inside the forming hole 13. When the situation occurs, the multiple groups of second electric telescopic rods 31 are started. As the multiple groups of second electric telescopic rods 31 are started, the output ends of the multiple groups of second electric telescopic rods 31 are synchronously telescoped and extended. At this time, the output ends of the multiple groups of second electric telescopic rods 31 will drive the extrusion sheet 3 to slide back and forth inside the forming hole 13. At this time, the sliding extrusion sheet 3 contacts the sealing ring stuck in the forming hole 13, and the sealing ring stuck in the forming hole 13 can be pushed out of the forming hole 13. Through the above structure, the sealing ring stuck in the forming hole 13 can be pushed out of the forming hole 13, thereby reducing the situation that the sealing ring is stuck in the forming hole 13 and the forming hole 13 is blocked, thereby reducing the situation that the subsequent sealing ring processing is affected by the blockage of the forming hole 13.

[0027] like Figure 1As shown, the middle parts of the two first electric telescopic rods 14 are connected with a connecting rod 4; the connecting rod 4 is located at the output end of the first electric telescopic rod 14. When working, by starting the first electric telescopic rod 14, the extrusion cylinder 12 and the raw material plate can be driven to contact, so that the sealing ring is processed. At this time, the connecting rod 4 is connected to the middle parts of the two first electric telescopic rods 14. At this time, starting one of the first electric telescopic rods 14 can drive the other first electric telescopic rod 14 to move synchronously. Through the above structure, the movement trajectories of the two first electric telescopic rods 14 can be made the same, thereby reducing the situation where the sealing ring processing is asynchronous due to the different movement trajectories of multiple extrusion cylinders 12.

[0028] like Figure 1 and Figure 4 As shown, two push rods 5 are directly installed on the opposite surfaces of multiple groups of the placement plates 15; the two push rods 5 are symmetrically arranged. When working, when the multiple placement plates 15 are installed in the middle of the first electric telescopic rod 14, the push rods 5 can be installed on the top of the multiple placement plates 15. At this time, the multiple placement plates 15 can be separated by the multiple push rods 5, so that gaps appear between the multiple placement plates 15. Through the above structure, the situation in which the raw material plate is difficult to place inside the placement groove 18 due to the multiple placement plates 15 being too closely fitted can be reduced.

[0029] like Figure 4 As shown, a baffle 6 is fixed to the bottom of the top plate 32; the bottom of the baffle 6 is fixed to the top of the support plate 1. When working, by starting multiple sets of second electric telescopic rods 31, the sealing ring inside the forming hole 13 can be demoulded. At this time, by installing the baffle 6 at the ends of the top plate 32 and the support plate 1, the multiple sets of second electric telescopic rods 31 can be surrounded by the inside of the baffle 6. Through the above structure, the multiple sets of second electric telescopic rods 31 can be protected, which reduces the situation where the multiple sets of second electric telescopic rods 31 are affected by external dust or impurities during work, thereby causing damage to the second electric telescopic rods 31.

[0030] like Figure 5 As shown, two baffles 7 are fixedly connected to the bottom of the first through hole 17 at the bottom; the two baffles 7 are symmetrically arranged. When working, the end of the first electric telescopic rod 14 can be blocked and limited by setting the baffles 7, thereby reducing the situation where the first electric telescopic rod 14 extends too long and extends to the outside of the placement plate 15, thereby causing multiple extrusion cylinders 12 to descend too deep.

[0031] During operation, multiple placement plates 15 are installed to the middle of the first electric telescopic rod 14. At this time, as the multiple placement plates 15 are installed to the specified positions, the multiple discharge holes 16 also correspond to the positions of the multiple extrusion cylinders 12. At this time, the raw materials of the sealing ring are placed in batches inside the placement groove 18. At this time, the raw materials of the sealing ring block the multiple discharge holes 16. At this time, by starting the first electric telescopic rods 14 on both sides, as the first electric telescopic rods 14 are started, the output end of the first electric telescopic rod 14 will be telescoped back and forth. At this time, when the first electric telescopic rod 14 is started, the extrusion cylinder 12 will gradually approach the inside of the discharge hole 16, and at the same time approach the raw material of the sealing ring until it fits with the raw material. At this time, continue to start the first electric telescopic rod 14. The first electric telescopic rod 14 continues to move, and the multiple extrusion cylinders 12 penetrate the multiple discharge holes 16 at the same time and extend to the bottom. At this time, the multiple extrusion cylinders 12 penetrate the raw materials of the sealing ring at the same time. At this time, the corresponding positions of the raw materials and the discharge holes 16 will be cut by the multiple extrusion cylinders 12. At this time, the O-shaped sealing ring will enter the interior of the forming hole 13 and buckle the block 21 in the interior of the card slot 2. At this time, as the block 21 is installed, the collection box 22 will also be in the corresponding position, that is, corresponding to the position of the multiple discharge holes 16. At this time, by starting the first electric telescopic rod 14, the extrusion cylinder 12 extrude the raw material plate, so that the sealing ring is formed. At this time, the formed sealing ring will fall off from the inside of the forming hole 13 and fall into the collection box 22. When the extrusion cylinder 12 extrude the raw material plate, the sealing ring will enter the inside of the forming hole 13. Due to gravity, a part of the sealing ring will directly fall into the inside of the collecting box 22. At the same time, a part of the sealing ring will be stuck in the inside of the forming hole 13 and it is difficult to fall off, thereby causing the inside of the forming hole 13 to be blocked. At this time, by starting the multiple groups of second electric telescopic rods 31, as the multiple groups of second electric telescopic rods 31 are started, the output ends of the multiple groups of second electric telescopic rods 31 are synchronously retracted and extended. At this time, the output ends of the multiple groups of second electric telescopic rods 31 will drive the extrusion sheet 3 to slide back and forth inside the forming hole 13. At this time, the sliding extrusion sheet 3 contacts the sealing ring stuck in the forming hole 13, and the sealing ring stuck in the forming hole 13 can be removed. 3, the sealing ring inside is pushed out of the forming hole 13, and by starting the first electric telescopic rod 14, the extrusion cylinder 12 and the raw material plate can be driven to contact, so that the sealing ring is processed. At this time, a connecting rod 4 is connected in the middle of the two first electric telescopic rods 14. At this time, starting one of the first electric telescopic rods 14 can drive the other first electric telescopic rod 14 to move synchronously. When multiple placement plates 15 are installed in the middle of the first electric telescopic rods 14, a push rod 5 can be installed on the top of the multiple placement plates 15. At this time, the multiple placement plates 15 can be separated by the multiple push rods 5, so that gaps appear between the multiple placement plates 15. By starting multiple groups of second electric telescopic rods 31, the sealing ring inside the forming hole 13 can be demoulded.At this time, by installing a baffle plate 6 at the ends of the top plate 32 and the support plate 1, multiple groups of second electric telescopic rods 31 can be surrounded inside the baffle plate 6.
