Description

Technical Field

[0001] The invention relates to the technical field of mold manufacturing, in particular to a rubber ring molding mold capable of reducing edge defects. Background Art

[0002] A molding mold, also known as a mold, is a mold made in proportion to the shape and structure of the actual object. It is a tool that uses pressing or pouring to make the material into a certain shape. Some rubber rings use the injection molding method.

[0003] The rubber ring making material is first heated and melted in the heating barrel of the injection molding machine, and then, under the push of the injection molding machine screw or piston, it enters the mold cavity through the nozzle and the mold pouring system, and finally hardens and sets in the cavity, which is a simple process of injection molding. The mold used for injection molding is called an injection molding mold. This mold is generally divided into an upper and lower part for the convenience of demolding. During the injection molding process, the injection molding material will be filled in the injection molding cavity between the upper and lower molds, and the airtightness of the injection molding cavity needs to be maintained during injection molding. During the injection molding process, the upper and lower molds need to be kept in a tightly fitted state. Therefore, during use, the upper and lower parts of the mold will often squeeze each other. With the increase of use time, the contact surface of the upper and lower molds will be more seriously worn, so that there is a large gap between the upper and lower molds during the injection molding process. The overall airtightness of the mold is poor, which will have an adverse effect on the normal injection molding of the mold. The injection molding material cannot be fully filled in the mold, and insufficient injection molding is prone to occur, resulting in defects in the rubber ring produced by injection molding, and the number of defective products will increase significantly, resulting in a serious waste of injection molding materials.

[0004] In addition, in order to facilitate demoulding, the inside of the mold is usually coated with a release agent. The injection port of the mold is relatively narrow, and the release agent is difficult to apply to the inner wall of the injection port. The injection molding material is easy to adhere to the inner wall of the injection port, which can easily cause the injection port to be blocked. The injection molding material cannot be injected into the mold normally, and it is difficult to fully clean the inside of the injection port by manual cleaning. If there is waste residue inside the injection port, these waste residues will increase the roughness of the inner wall of the injection port, and the injection molding material will be more likely to adhere to the inside of the injection port, causing the mold to be frequently blocked.

[0005] Therefore, a rubber ring forming die capable of reducing edge defects is proposed. Summary of the invention

[0011] Preferably, a slope is provided on one side of the lifting block close to the pressing block, a slope is provided on one side of the baffle close to the lifting block, and a sealing gasket is provided on the inner side of the ferrule.

[0012] Preferably, a water pump is fixedly connected to one side of the top of the water tank close to the detection box, a water pipe is fixedly connected to the outside of the water pump, one end of the water pipe away from the water tank is fixedly connected to a water injection cylinder, and clean water is stored inside the water tank.

[0013] Preferably, an eccentric circular block is fixedly connected to one side of the disc close to the lifting plate, and a straight groove matching the eccentric circular block is formed on the lifting plate.

[0014] Preferably, a spiral groove is provided on the outer side of the rotating drum, a collar corresponding to the position of the rotating drum is fixedly connected to the side of the mounting plate close to the rotating drum, and an embedded block adapted to the spiral groove is fixedly connected to the inner side of the collar.

[0015] Preferably, a sliding block is fixedly connected to one side of the connecting plate close to the mounting plate, and a sliding groove matching the sliding block is provided on the straight plate.

[0016] Preferably, a detection box is fixedly connected to the outside of the water tank, the detection box and the water tank are communicated with each other, a trigger block is slidably connected inside the detection box, a limiting spring is fixedly connected to the top of the trigger block, a pull rope is fixedly connected to the bottom of the trigger block, a floating plate is fixedly connected to the lower end of the pull rope, and an alarm switch corresponding to the position of the trigger block is fixedly connected inside the detection box.

[0017] Preferably, an alarm is fixedly connected to the outside of the water tank, and the alarm switch is electrically connected to the alarm.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. Since the drum and the water injection drum are interconnected, the cleaning water in the water injection drum can be sprayed into the injection tube through the nozzle on the outside of the drum. When the drum rotates, the cleaning water sprayed by the nozzle can be evenly sprayed on the inner wall of the injection tube. At the same time, the soft brush fixed on the outside of the drum will also clean the residues attached to the inner wall of the injection tube. The soft brush is relatively soft in texture. After frequent contact with the inner wall of the injection tube, it will not leave a large number of scratches on the inner wall of the injection tube, so that the inner wall of the injection tube can remain relatively smooth, which can reduce the adhesion of the injection material to the inner wall of the injection tube, and can also avoid frequent blockage inside the injection tube, which is conducive to the continuous and smooth injection work;

[0020] 2. A slider is fixedly connected to the side of the connecting plate close to the straight plate. A slide groove matching the slider is provided on the straight plate. When the lifting plate moves up and down, the slider also slides synchronously inside the slide groove, which strengthens the connection between the connecting plate and the straight plate, reduces the pressure on the lifting plate during the up and down movement, and prevents the lifting plate from bending due to the gravity of the water injection cylinder, which plays a good protective role on the lifting plate and is conducive to extending the service life of the lifting plate;

[0021] 3. The trigger block after moving downward will cause pressure on the alarm switch. The alarm electrically connected to the alarm switch will be energized and sound an alarm, notifying the staff to add cleaning water to the water tank in time. After the water level rises, the floating plate no longer pulls the pull rope downward. At this time, the limit spring rebounds and drives the trigger block to move upward. The trigger block no longer contacts the alarm switch, and the alarm stops working. Through the above setting, when the water level in the water tank is insufficient, an alarm can be sounded in time to notify the staff near the mold to add cleaning water to the water tank in time, ensuring a better cleaning effect when the drum rotates;

[0022] 4. By setting the side closing component, during the mold closing process, the baffle will be clamped inside the ferrule, which will seal the side of the mold. When the mold is aged and worn, it can ensure good airtightness between the upper and lower molds. The air pressure in the mold can meet the needs of normal injection molding, and the injection molding material can be fully filled in the cavity in the mold, effectively reducing the situation of insufficient injection molding, thereby reducing the number of rubber rings with edge defects produced, and improving the utilization rate of injection molding materials.

[0040] By setting up the side closing component, during the mold closing process, the baffle 54 will be clamped in the sleeve 55, which will seal the side of the mold. When the mold is aged and worn, it can ensure good airtightness between the upper and lower molds 2. The air pressure in the mold can meet the needs of normal injection molding, and the injection material can be fully filled in the cavity in the mold, effectively reducing the situation of insufficient injection molding, thereby reducing the number of rubber rings with edge defects produced, improving the utilization rate of injection molding materials, and obtaining higher production benefits.

[0041] The pipeline cleaning assembly includes a slide rail 61 fixedly connected to the side of the upper mold 1 close to the injection molding tube 3, a mounting plate 62 is slidably connected inside the slide rail 61, a cushion block 63 is fixedly connected to the top of the mounting plate 62, a driving motor 64 is fixedly connected to the top of the cushion block 63, a straight plate 65 is fixedly connected to the side of the mounting plate 62 close to the cushion block 63, a disc 66 is fixedly connected to the output shaft of the driving motor 64, a buckle 67 is fixedly connected to the side of the straight plate 65 close to the disc 66, a lifting plate 68 is slidably connected inside the buckle 67, an eccentric circular block is fixedly connected to the side of the disc 66 close to the lifting plate 68, and the lifting plate 66 is fixedly connected to the side of the disc 66 close to the lifting plate 68. 8 is provided with a straight groove adapted to the eccentric circular block, two buckles 67 are on the same vertical straight line, the upper end of the lifting plate 68 is fixedly connected to a connecting plate 69, the bottom of the connecting plate 69 is fixedly connected to a water injection cylinder 610, the outer side of the water injection cylinder 610 is rotatably connected to a rotating cylinder 611, the outer side of the rotating cylinder 611 is provided with a spiral groove, the side of the mounting plate 62 close to the rotating cylinder 611 is fixedly connected to a sleeve corresponding to the position of the rotating cylinder 611, the inner side of the sleeve is fixedly connected to an embedded block adapted to the spiral groove, the outer side of the rotating cylinder 611 is fixedly connected to a nozzle 612, and the bottom of the rotating cylinder 611 is fixedly connected to a soft brush 613;

[0042] Since the rotating drum 611 and the water injection drum 610 are interconnected, the cleaning water in the water injection drum 610 can be sprayed into the injection tube 3 through the nozzle 612 on the outside of the rotating drum 611. When the rotating drum 611 rotates, the cleaning water sprayed by the nozzle 612 can be evenly sprayed on the inner wall of the injection tube 3. At the same time, the soft brush 613 fixed on the outside of the rotating drum 611 will also clean the residues attached to the inner wall of the injection tube 3. The soft brush 613 is relatively soft in texture. After frequent contact with the inner wall of the injection tube 3, it will not leave a large number of scratches on the inner wall of the injection tube 3, so that the inner wall of the injection tube 3 can be kept in a relatively smooth state, which can reduce the adhesion of the injection molding material to the inner wall of the injection tube 3, and can avoid frequent blockages inside the injection tube 3, which is conducive to the continuous and smooth injection work.

[0043] A slider is fixedly connected to one side of the connecting plate 69 close to the straight plate 65, and a slide groove compatible with the slider is opened on the straight plate 65. When the lifting plate 68 moves up and down, the slider also slides synchronously inside the slide groove, thereby strengthening the connection relationship between the connecting plate 69 and the straight plate 65, reducing the pressure on the lifting plate 68 during the up and down movement, and preventing the lifting plate 68 from bending due to the gravity of the water injection cylinder 610, which has a better protective effect on the lifting plate 68 and is beneficial to extending the service life of the lifting plate 68.

[0044] A water pump 78 is fixedly connected to one side of the top of the water tank 4 near the detection box 71, and a water pipe 79 is fixedly connected to the outside of the water pump 78. The end of the water pipe 79 away from the water tank 4 is fixedly connected to the water injection cylinder 610, and a detection box 71 is fixedly connected to the outside of the water tank 4. The detection box 71 and the water tank 4 are connected to each other. A trigger block 72 is slidably connected inside the detection box 71, and a limit spring 73 is fixedly connected to the top of the trigger block 72. A pull rope 74 is fixedly connected to the bottom of the trigger block 72, and a floating plate 75 is fixedly connected to the lower end of the pull rope 74. An alarm switch 76 corresponding to the position of the trigger block 72 is fixedly connected inside the detection box 71, and an alarm 77 is fixedly connected to the outside of the water tank 4. The alarm switch 76 The trigger block 72 is electrically connected to the alarm 77, and the downward movement of the trigger block 72 will cause pressure on the alarm switch 76. The alarm 77 electrically connected to the alarm switch 76 is energized and sounds an alarm, notifying the staff to replenish the cleaning water in the water tank 4 in time. After the water level rises, the floating plate 75 no longer pulls the pull rope 74 downward. At this time, the limit spring 73 rebounds and drives the trigger block 72 to move upward. The trigger block 72 no longer contacts the alarm switch 76, and the alarm 77 stops working. Through the above-mentioned arrangement, when the water level in the water tank 4 is insufficient, an alarm can be sounded in time, notifying the staff near the mold to replenish the cleaning water in the water tank 4 in time, to ensure that the rotating drum 611 can have a better cleaning effect when it rotates.

[0045] Working principle:

[0046] During operation, the staff will place the upper mold 1 on the lower mold 2. During this period, the upper mold 1 will slowly move closer to the lower mold 2, and the lower pressing block 52 fixed at the bottom of the upper mold 1 will be inserted into the extrusion groove 51 opened on the lower mold 2. Because the extrusion groove 51 is a U-shaped groove, the lower pressing block 52 will move vertically downward for a distance inside the extrusion groove 51, and then the lower pressing block 52 will contact the lifting block 53 at the bottom of the extrusion groove 51. The lifting block 53 is provided with an inclined surface on one side close to the lower pressing block 52. After the lower pressing block 52 contacts the lifting block 53, the lifting block 53 It will move close to the baffle 54 clamped on the other end of the extrusion groove 51. The side of the baffle 54 close to the lifting block 53 is also provided with an inclined surface. After the baffle 54 is resisted by the lifting block 53, the baffle 54 will move upward. When the lower pressing block 52 is fully inserted into the extrusion groove 51, the top of the baffle 54 will be clamped in the clamping sleeve 55 at the bottom of the upper mold 1. A sealing gasket is fitted inside the clamping sleeve 55. The sealing gasket can reduce the gap between the clamping sleeve 55 and the baffle 54. In addition, the sealing gasket is made of high temperature resistant material and will not be damaged by heat during the injection molding process.

[0047] By setting up the side closing component, during the mold closing process, the baffle 54 will be clamped in the sleeve 55, which will seal the side of the mold. When the mold is aged and worn, it can ensure good airtightness between the upper and lower molds 2. The air pressure in the mold can meet the needs of normal injection molding, and the injection material can be fully filled in the cavity in the mold, effectively reducing the situation of insufficient injection molding, thereby reducing the number of rubber rings with edge defects produced, improving the utilization rate of injection molding materials, and obtaining higher production benefits.

[0048] The staff turns on the water pump 78, and the water pump 78 can transport the cleaning water in the water tank 4 to the inside of the water injection cylinder 610 through the water pipe 79. Since the amount of water stored in the water tank 4 is limited, the water in the water tank 4 will be continuously consumed during the cleaning process of the injection tube 3. In the case of water shortage, the cleaning effect of the soft brush 613 on the injection tube 3 becomes poor. Therefore, a detection box 71 is provided on the outside of the water tank 4, and the detection box 71 is interconnected with the water tank 4, so the water tank 4 and the detection box 71 have the same horizontal plane height. Since the floating board 75 is light in weight and can float on the water surface, the pull rope 74 connected to the floating board 75 will not pull the trigger block 72 downward. When the water in the water tank 4 is consumed in large quantities, due to the limited length of the pull rope 74, the floating board 75 cannot move downward with the horizontal plane. , making the floating plate 75 in a suspended state, the pull rope 74 is affected by the gravity of the floating plate 75 to drive the trigger block 72 to move downward, and the trigger block 72 after moving downward will cause pressure on the alarm switch 76, and the alarm 77 electrically connected to the alarm switch 76 is energized and sounds an alarm, notifying the staff to replenish the cleaning water in the water tank 4 in time. After the water level rises, the floating plate 75 no longer pulls the pull rope 74 downward. At this time, the limit spring 73 rebounds and drives the trigger block 72 to move upward. The trigger block 72 no longer contacts the alarm switch 76, and the alarm 77 stops working. Through the above arrangement, when the water level in the water tank 4 is insufficient, an alarm can be issued in time to notify the staff near the mold to replenish the cleaning water in the water tank 4 in time, ensuring that the rotating drum 611 can have a better cleaning effect when it rotates.

[0049] In order to avoid obstruction to the injection molding tube 3, during the injection molding process, the mounting plate 62 needs to be moved to a position away from the injection molding tube 3. When the injection molding tube 3 is to be cleaned, the mounting plate 62 is moved to a position corresponding to the injection molding tube 3 through the slide rail 61. The staff needs to connect the drive motor 64 to an external power supply. At this time, the drive motor 64 will drive the disc 66 fixed on its output shaft to rotate. A straight plate 65 is vertically installed on the top of the mounting plate 62. Two buckles 67 for fixing the lifting plate 68 are fixedly connected to the side of the straight plate 65 away from the drive motor 64. The two buckles 67 are on the same vertical line, so that the lifting plate 68 remains vertical to the ground. A straight groove is provided on the lifting plate 68. An eccentric block fixedly connected to the outer side of the disc 66 is clamped in the straight groove. When the disc 66 rotates, the lifting plate 68 is driven by the eccentric block. When moving up and down in the vertical direction, the cushion block 63 plays a role of raising the drive motor 64, so that the lifting plate 68 will not collide with the mounting plate 62 during the movement. The upper end of the lifting plate 68 is fixedly connected to a connecting plate 69, and the bottom of the connecting plate 69 is fixedly connected to a water injection cylinder 610 corresponding to the position of the injection tube 3. A slider is fixedly connected to the side of the connecting plate 69 close to the straight plate 65, and a slide groove compatible with the slider is opened on the straight plate 65. When the lifting plate 68 moves up and down, the slider is also driven to slide synchronously inside the slide groove, thereby strengthening the connection relationship between the connecting plate 69 and the straight plate 65, reducing the pressure on the lifting plate 68 during the up and down movement, and preventing the lifting plate 68 from bending due to the gravity of the water injection cylinder 610, which has a good protective effect on the lifting plate 68 and is beneficial to extending the service life of the lifting plate 68.

[0050] During the up and down movement of the lifting plate 68, the straight plate 65 and the ring fixed on one side of the straight plate 65 are in a relatively static state. Driven by the up and down movement of the lifting plate 68, the rotating drum 611 connected to the bottom of the water injection cylinder 610 will be inserted back and forth inside the ring. Since the embedded block fixed on the inner side of the ring is clamped in the spiral groove opened on the outer side of the rotating drum 611, if the ring remains stationary, the movement of the rotating drum 611 inside the ring will cause the rotating drum 611 to rotate. Since the rotating drum 611 and the water injection cylinder 610 are interconnected, the cleaning water in the water injection cylinder 610 can be sprayed to the outside of the rotating drum 611 through the nozzle 612 on the outer side of the rotating drum 611. Inside the injection tube 3, when the drum 611 rotates, the cleaning water sprayed by the nozzle 612 can be evenly sprayed on the inner wall of the injection tube 3. At the same time, the soft brush 613 fixed on the outside of the drum 611 will also clean the residues attached to the inner wall of the injection tube 3. The soft brush 613 is relatively soft in texture. After frequent contact with the inner wall of the injection tube 3, it will not leave a large number of scratches on the inner wall of the injection tube 3, so that the inner wall of the injection tube 3 can remain in a relatively smooth state, which can reduce the adhesion of the injection molding material on the inner wall of the injection tube 3, and can avoid frequent blockages inside the injection tube 3, which is conducive to the continuous and smooth progress of the injection molding work.
