DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] See also Figure 1-Figure 8The present invention provides a technical solution: an injection mold for a rearview mirror of an automobile, comprising: a die 1 with a mold cavity on the side, a glue injection port on one side of the die 1, the mold cavity and the punch 2 are matched correspondingly, and when the die 1 and the punch 2 are molded together, a glue injection space is formed between the mold cavity and the mold core 14; the punch 2 is fixedly connected to one side of the die 1, and a positioning boss 7 is fixedly connected to the side of the die 2 close to the die 1, and a driving plate 4 is fixedly connected to one side of the positioning boss 7, and multiple groups of mold cores 14 are fixedly connected to one side of the driving plate 4, and a ejector pin 15 is fixedly connected to the side of the die 2 away from the positioning boss 7 through a nut; a linkage component is placed on the outside of the punch 2, and the linkage component includes a linkage rod 9 slidably arranged on the outside of the punch 2, the linkage rod 9 is slidably connected to the die 1, the linkage rod 9 is an L-shaped structure, the die 1 is provided with a rectangular hole matched with the linkage rod 9, and the linkage rod 9 is drivingly connected to the driving plate 4; the linkage The processing assembly is placed on the outside of the punch 2, and the linkage processing assembly includes a fixed bracket 18 fixed to the outside of the punch 2 by bolts. A lifting rod 24 is slidably connected to one side of the fixed bracket 18. A cleaning nozzle 26 and a cleaning brush 25 for cleaning are fixed to the bottom of the lifting rod 24. The cleaning brush 25 includes a cylinder and a brush head. A No. 3 spring 27 is arranged on the top of the cleaning brush 25. A fixed cylinder 31 for placing a release agent bottle is placed on the top of the cleaning brush 25. A linkage pressing part is arranged on the fixed cylinder 31 for pressing the switch on the top of the release agent bottle; the die 1 drives the ejector 15 to be demolded by the driving plate 4 through the linkage pull rod 9, and the linkage processing assembly drives the cleaning brush 25 to move downward through the lifting rod 24 to clean the mold core 14. When the lifting rod 24 moves to the limit position, the linkage pressing part presses the release agent bottle to spray the release agent on the mold core 14.

[0032] It should be noted that the present invention sets corresponding connections between the die 1 and the base plate 3, so that the rod punch 2 is fixed in place and does not move. The hydraulic cylinder or other driving components are horizontally fixed through the die 1, so as to realize the closing and parting actions. When closing the mold, under the action of the No. 1 spring 6 pushing the driving plate 4, the driving plate 4 drives the linkage rod 9 to move to one side of the base plate 3. At this time, the connecting angle iron 11 lifts the lifting rod 24 upward through the wire rope 22 and the No. 2 pulley 21 and the No. 1 pulley 20 on the outside of the fixed bracket 18, so that the cleaning brush 25 and the wire rope 22 form a height difference, so as not to affect the closing and injection molding of the die 1 and the punch 2. When parting the mold, when the die 1 does not contact the end of the linkage rod 9, the cleaning brush 25 and the lifting rod 24 are stationary. When the die 1 contacts the end of the linkage rod 9 away from the base plate 3, the die 1 The linkage pull rod 9 is driven to the side away from the punch 2. At this time, the linkage pull rod 9 drives the ejector 15 to move through the drive plate 4 to realize demoulding. Under the linkage action, the lifting rod 24 drives the cleaning brush 25 to clean the mold core 14 and the ejector 15, and blows up and cleans the die 1 through the cleaning nozzle 26. When the cleaning brush 25 moves to the preset position, the pull rod 32 drives the fixed cylinder 31 to move downward, so that the pressing head on the top of the spray-type demoulding agent bottle contacts with the L-shaped plate 29. At this time, the spray-type demoulding agent bottle sprays the demoulding agent on the mold core 14. At the same time, under the action of the timing switch, the cylinder of the cleaning brush 25 drives the brush head to retract briefly to prevent the cleaning brush 25 from contacting the mold core 14 when it is reset. When the mold is closed, the die 1 moves toward the punch 2, and the No. 1 spring 6 drives the mold core 14 to reset through the drive plate 4, and drives the cleaning brush 25 to reset through the linkage pull rod 9.

[0033] like Figure 2 , 3 As shown in 4, the four corners of one side of the die 1 are fixed with positioning columns, the punch 2 is provided with positioning holes corresponding to the positions of the positioning columns, the positioning boss 7 is provided with inclined structures at the four corners, and the outer sides of the inclined structures are fixed with positioning blocks 8, and one side of the die 1 is provided with a limiting groove that cooperates with the positioning block 8.

[0034] It should be noted that, the four corners of one side of the die 1 of the present invention are fixedly connected with positioning columns, and the positioning columns match the holes of the punch 2, which can ensure that the punch 2 can be accurately positioned when the mold is closed; the inclined surface design of the four corners of the positioning boss 7 helps to achieve better centering and guiding during the mold closing process, and the positioning block 8 cooperates with the limiting groove on the die 1 to further ensure the position and stability of the punch 2 during the mold closing; during this period, the limiting groove and the positioning block 8 interact with each other to limit the movement of the punch 2 during the mold closing process, thereby ensuring the precise closure of the mold and the accurate molding of the product.

[0035] like Figure 4As shown, it also includes cooling holes 16, which are equidistantly opened in the middle of the positioning boss 7. The cooling holes 16 are staggered with the ejector pins 15. The interior of the cooling hole 16 is detachably connected to a cooling pipe 17, and a metal rod is installed inside the cooling pipe 17. The outer side of the metal rod is provided with metal fins that are tilted downward in the opposite direction of the water flow.

[0036] It should be noted that the cooling pipe 17 of the present invention is inserted into the cooling hole 16, and the two are completely fitted. The cooling pipe 17 is fixed at the end of the cooling pipe 17 by bolts and a fixing plate, and then a sealing cover is installed at the end, and the sealing cover is connected by a bent pipe, so that the cooling water presents an S-shaped path shape inside the punch 2, and the inside of the cooling pipe 17 is fixedly connected to the sealing cover by screws. A metal rod is provided on the outer side of the metal rod at an angle in the opposite direction of the water flow. The metal fins form a certain angle with the direction of the water flow. The barrier of the metal fins and the collision with the water prolong the contact time between the water and the pipe wall, thereby improving the heat transfer efficiency, because scale may indeed appear on the cooling water pipe after long-term use. Scale is a hard residue formed by the crystallization and precipitation of minerals such as calcium and magnesium dissolved in water after heating. When cleaning the scale, the cooling tube 17 can be directly dismantled and replaced or removed for cleaning. After the cooling tube 17 is removed, it is more convenient to clean it in its smaller size, without the need to disassemble the entire mold or clean the mold itself. In addition, when the metal rod is taken out, its metal fins can also scrape and clean the inner wall of the cooling tube 17.

[0037] like Figure 1 , 2 As shown in Figure 3, two supporting side plates 10 are fixedly connected to one side of the punch 2, the ends of the supporting side plates 10 are fixedly connected to the bottom plate 3, the driving plate 4 is slidably installed between the two supporting side plates 10, a supporting column 5 is fixedly connected between the punch 2 and the bottom plate 3, the supporting column 5 is slidably connected to the driving plate 4, and a No. 1 spring 6 is sleeved on the outer side of the supporting column 5 and located between the punch 2 and the driving plate 4.

[0038] It should be noted that the elastic force of the No. 1 spring 6 of the present invention is greater than the elastic force of the No. 3 spring 27. When the mold is closed, when the die 1 is separated from the end of the linkage rod 9, the No. 1 spring 6 pushes the drive plate 4 to slide on the outside of the support column 5, and the drive plate 4 drives the linkage rod 9 to reset. The linkage rod 9 drives the lifting rod 24 to reset by connecting the angle iron 11 and the wire rope 22, thereby realizing automatic reset of each part, which is convenient for the next injection molding process and cleaning.

[0039] like Figure 1 , 3As shown, a limiting slide groove 19 is provided in the middle of the supporting side plate 10, and a connecting block is slidably connected in the limiting slide groove 19. The driving plate 4 and the linkage rod 9 are both fixedly connected to the connecting block. A connecting angle iron 11 is fixedly connected to the end of the linkage rod 9, and a guide rod 12 is slidably connected to the middle of the connecting angle iron 11. The guide rod 12 is fixedly connected to the base plate 3, and a baffle is fixedly connected to the end of the guide rod 12 away from the base plate 3. A second spring 13 is fixedly connected to the outer side of the guide rod 12 and between the connecting angle iron 11 and the baffle for driving the connecting angle iron 11 to reset.

[0040] It should be noted that, in the present invention, when the No. 1 spring 6 drives the linkage rod 9 to reset through the driving plate 4, the No. 2 spring 13 pushes the connecting angle iron 11, and drives the linkage rod 9 to move to one side of the bottom plate 3 through the connecting angle iron 11. Under the limiting and guiding action of the limiting slide groove 19 and the guide rod 12, the linkage rod 9 can move horizontally and stably on the outside of the punch 2. At the same time, under the double-layer push of the No. 2 spring 13 and the No. 1 spring 6, the wire rope 22 pulls the lifting rod 24 to compress the No. 3 spring 27, so that the lifting rod 24 can be quickly reset.

[0041] like Figure 5 , 6 As shown, a No. 2 pulley 21 is installed on the top of the fixed bracket 18, a No. 1 pulley 20 is fixedly connected to the bottom of the fixed bracket 18 near the side of the connecting angle iron 11, a steel wire rope 22 is fixedly connected to the middle of the connecting angle iron 11, and the other end of the steel wire rope 22 passes through the bottom of the No. 1 pulley 20 and the top of the No. 2 pulley 21 in turn and is connected to the steel wire rope 22, a fixed plate 28 is fixedly connected to one side of the fixed bracket 18, a lifting rod 24 is slidably connected to the fixed plate 28, and a No. 3 spring 27 is sleeved on the outside of the lifting rod 24 and is located between the fixed plate 28 and the cleaning brush 25.

[0042] It should be noted that, in the present invention, when the linkage pull rod 9 drives the connecting angle iron 11 to reset, the connecting angle iron 11 pulls the wire rope 22 to move toward one end. Under the guidance of the No. 1 pulley 20 and the No. 2 pulley 21, one end of the wire rope 22 pulls the bottom of the lifting rod 24 upward. A brush is installed under the No. 1 pulley 20, and the brush is stained with grease to facilitate its smoother operation. The lifting rod 24 drives the cleaning brush 25 to move upward. While the cleaning brush 25 moves upward, the No. 3 spring 27 is compressed between the cleaning brush 25 and the fixed plate 28. When the mold is separated again, the No. 3 spring 27 pushes the cleaning brush 25 to move downward to achieve cleaning again.

[0043] like Figure 1 , 2As shown in Figures 3, 4, 5, 6, 7 and 8, a magnet 23 is fixed to one side of the top of the lifting rod 24, and a magnetic switch 38 corresponding to the magnet 23 is provided on one side of the fixed bracket 18. The magnetic switch 38 is electrically connected to the solenoid valve of the cleaning air nozzle 26, and the cleaning air nozzle 26 is fixed to the side of the cleaning brush 25 away from the bristles.

[0044] It should be noted that the cleaning air nozzle 26 of the present invention is connected to the air source through the air duct and the solenoid valve. During mold separation, when the cleaning air nozzle 26 corresponds to the mold cavity, the magnetic switch 38 corresponds to the magnet 23. Under the action of power, the timing switch starts to control the solenoid valve of the cleaning air nozzle 26 to work, so that the cleaning air nozzle 26 blows up the mold cavity to clean it during the downward process of the corresponding mold cavity. When the time reaches the preset time, the solenoid valve is closed and the cleaning air nozzle 26 stops working, thereby realizing the cleaning brush 25 cleaning the mold core 14 and the cleaning air nozzle 26 cleaning the concave mold 1.

[0045] like Figure 2 , 6 As shown, the linkage pressing part includes an L-shaped plate 29 fixedly connected to the top of the cleaning brush 25, and a fixed cylinder 31 is located below the L-shaped plate 29. The middle part of the L-shaped plate 29 is slidably connected with a lifting slider 30, and the lifting slider 30 is fixedly connected to the fixed cylinder 31. The top of the fixed cylinder 31 is fixedly connected with a pull rod 32, and the top of the pull rod 32 is threadedly connected with a limiting ring. The outer side of the L-shaped plate 29 is fixedly connected to a limiting baffle, and the No. 2 pulley 21 is slidably connected to the limiting baffle. The outer side of the pull rod 32 is located between the lifting slider 30 and the limiting baffle and is sleeved with a No. 4 spring 33. The outer side of the pull rod 32 is slidably connected to a limiting bracket 34, and the limiting bracket 34 is fixed to the fixed bracket 18.

[0046] It should be noted that the limit bracket 34 of the present invention is fixed to the side of the fixing plate 28 by bolts. The height of the limit bracket 34 can be adjusted according to processing needs. When the No. 3 spring 27 pushes the cleaning brush 25 to move downward, the cleaning brush 25 drives the L-shaped plate 29 to move downward. Under the elastic force of the No. 4 spring 33, the L-shaped plate 29 drives the pull rod 32 to move downward. When the limit ring on the outer side of the pull rod 32 contacts the limit bracket 34, the elastic force of the No. 3 spring 27 is greater than the No. 4 spring 33, so that the cleaning brush 25 drives the L-shaped plate 29 to continue to move downward. Under the action, the pull rod 32 pulls the fixed cylinder 31 upward through the lifting slider 30, and the fixed cylinder 31 drives the spray-type release agent bottle to move upward, so that the push switch on the top is pressed, so that the internal release agent is sprayed onto the mold core 14. A touch switch is provided on the top of the limit bracket 34. When the touch switch contacts the limit ring, the timing switch connected to the cylinder solenoid valve of the cleaning brush 25 is energized, and the cylinder of the cleaning brush 25 drives the brush head to retract to prevent the cleaning brush 25 from contacting the mold core 14 when it is reset. When the timing is over, the cylinder drives the brush head to reset, which is convenient for the next cleaning.

[0047] like Figure 7 As shown, a fastening bolt 37 is threadedly connected to the middle of the fixing cylinder 31, and the end of the fastening bolt 37 is rotatably connected to a fixing clamp. An adjusting bolt 36 is threadedly connected to the top of the L-shaped plate 29, and a pressing plate 35 is rotatably connected to the bottom of the adjusting bolt 36 for pressing the release agent bottle switch.

[0048] It should be noted that, when the present invention requires placing the spray-type release agent bottle, the adjusting bolt 36 is rotated so that the adjusting bolt 36 drives the pressure plate 35 to rise, so that there is enough space under the L-shaped plate 29 to place the spray-type release agent bottle in the fixed cylinder 31. After the placement is completed, the fastening bolt 37 is rotated so that the fastening bolt 37 drives the fixed clamp to squeeze and fix the spray-type release agent bottle in the fixed cylinder 31. The height of the pressure plate 35 is adjusted by adjusting the bolt 36, so that when the pull rod 32 drives the fixed cylinder 31 to move upward, the top of the spray-type release agent bottle can contact the pressure plate 35 to realize the pressing operation.
