Description

Technical Field

[0001] This utility model relates to the field of dust cover production technology, specifically to a dust cover mold ejection structure. Background Technology

[0002] Dust covers are a common industrial product, often used in linear telescopic mechanical structures. Their purpose is to prevent dust and mud from entering the mating mechanism. They are mostly made of rubber and are usually molded.

[0003] However, during the processing of many dust covers, the mold generally needs to be manually removed from the molding groove, which not only reduces production efficiency, but also causes the dust cover to tear due to uneven force.

[0004] In view of this, the present invention proposes a dust cover mold ejection structure. Utility Model Content

[0005] This utility model proposes a dust cover mold ejection structure, which solves the problem that in many current dust cover processing, the mold generally needs to be manually removed from the forming groove, which not only reduces production efficiency, but also causes the dust cover to be torn due to uneven force.

[0006] The technical solution of this utility model is as follows: A dust cover mold ejection structure includes a forming groove, telescopic rods fixedly connected to both sides of the forming groove, a connecting plate fixedly connected to the top of the telescopic rods, a mold body fixedly connected to the surface of the connecting plate, a force-bearing plate fixedly connected to the connecting plate on one side of the mold body, a sealing plate fixedly connected to the surface of the forming groove by screws, a sliding groove provided on the surface of the sealing plate, a motor fixedly connected to the forming groove on the left side of the sealing plate, a first gear fixedly connected to the output end of the motor, a second gear meshing with the side of the first gear, a positive and negative screw fixedly connected to the back of the second gear and rotatably connected to the inside of the forming groove, two sets of transmission plates slidably connected to the forming groove threadedly connected to the surface of the positive and negative screws, a transmission rod fixedly connected to the top of each of the two sets of transmission plates, two sets of ejection plates slidably connected to the inside of the forming groove, and a connecting groove slidably connected to the transmission rod on the surface of each of the two sets of ejection plates.

[0007] Preferably, a bracket is fixedly connected to the bottom of the molding groove, a rubber pad is fixedly connected to the bottom of the bracket, and a groove is provided on the side of the bracket.

[0008] Preferably, the groove size is larger than the positive and negative screws, and the positive and negative screws are located inside the groove after the sealing plate is assembled.

[0009] Preferably, the positive and negative screws are located at the center point of the second gear, and the positive and negative screws cause the two sets of transmission plates to slide in opposite directions.

[0010] Preferably, the connecting groove is inclined and fits tightly with the transmission rod.

[0011] Preferably, the top of the ejector plate is flush with the top of the forming groove, and the top of the ejector plate is in contact with the force-bearing plate.

[0012] Preferably, the rubber pad is made of non-slip rubber and completely covers the bottom of the bracket.

[0013] Preferably, the groove extends through the bracket.

[0014] The working principle and beneficial effects of this utility model are as follows:

[0015] 1. In this utility model, a first gear is set up, and the motor is turned on to control the first gear to rotate. The second gear rotates accordingly and drives the positive and negative screws to rotate. At this time, the two sets of transmission plates will slide in opposite directions along the inside of the forming groove when the positive and negative screws rotate. When the two sets of transmission plates approach each other, they will control the two sets of transmission rods to also approach and slide along the inside of the connecting groove. Since the connecting groove is in an inclined state, when the transmission rods move, they will apply an upward pushing force to the ejector plate. When the ejector plate moves upward, it will apply an upward pushing force to the force plate. The force plate will then apply a pushing force to the connecting plate. Under the limit of the telescopic rod, the connecting plate will move horizontally upward, and the mold body will be ejected accordingly.

[0016] 2. In this utility model, by setting a sliding groove, the sealing plate will not interfere with the positive and negative screws during installation. When disassembling the sealing plate, the screws can be removed and the sealing plate can be pushed upward. By setting a rubber pad, the whole device can be shock-absorbing and anti-slip. In addition, the groove makes it easy to move the forming groove through the groove, avoiding the bottom of the forming groove from being directly attached to the table surface, which would make it difficult to move.

[0024] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0025] Example 1

[0026] A preferred embodiment of the dust cover mold ejection structure provided by this utility model is, for example... Figures 1 to 5 As shown: A dust cover mold ejection structure includes a forming groove 1, with telescopic rods 2 fixedly connected to both sides of the forming groove 1, a connecting plate 3 fixedly connected to the top of the telescopic rods 2, a mold body 4 fixedly connected to the surface of the connecting plate 3, a force-bearing plate 5 fixedly connected to the connecting plate 3 on one side of the mold body 4, a sealing plate 6 fixedly connected to the surface of the forming groove 1 by screws, a sliding groove 7 provided on the surface of the sealing plate 6, a motor 8 fixedly connected to the forming groove 1 on the left side of the sealing plate 6, a first gear 9 fixedly connected to the output end of the motor 8, a second gear 10 meshing with the side of the first gear 9, a positive and negative screw 11 fixedly connected to the back of the second gear 10 and rotatably connected to the inside of the forming groove 1, two sets of transmission plates 12 slidably connected to the forming groove 1 on the surface of the positive and negative screw 11, a transmission rod 13 fixedly connected to the top of each set of transmission plates 12, two sets of ejection plates 14 slidably connected to the inside of the forming groove 1, and a connecting groove 15 slidably connected to the transmission rod 13 on the surface of each set of ejection plates 14.

[0027] In this embodiment, the size of the groove 7 is larger than that of the positive and negative screws 11. After the sealing plate 6 is assembled, the positive and negative screws 11 are located inside the groove 7. By setting the groove 7, the sealing plate 6 will not interfere with the positive and negative screws 11 when it is installed.

[0028] In this embodiment, the positive and negative screws 11 are located at the center point of the second gear 10. The positive and negative screws 11 cause the two sets of transmission plates 12 to slide in opposite directions. When the motor 8 is turned on, it controls the first gear 9 to rotate, and the second gear 10 rotates accordingly, driving the positive and negative screws 11 to rotate. At this time, the two sets of transmission plates 12 will slide in opposite directions along the inside of the molding groove 1 when the positive and negative screws 11 rotate.

[0029] In this embodiment, the connecting groove 15 is inclined and fits tightly with the transmission rod 13. When the two sets of transmission plates 12 approach each other, the two sets of transmission rods 13 will also approach and slide along the inside of the connecting groove 15. Since the connecting groove 15 is inclined, when the transmission rod 13 moves, it will apply an upward pushing force to the ejector plate 14. When the ejector plate 14 moves upward, it will apply an upward pushing force to the force plate 5. The force plate 5 will then apply a pushing force to the connecting plate 3. Under the limit of the telescopic rod 2, the connecting plate 3 moves horizontally upward, and the mold body 4 will be ejected.

[0030] In this embodiment, the top of the ejector plate 14 is flush with the top of the forming groove 1, and the top of the ejector plate 14 is in contact with the force plate 5, which can prevent the ejector plate 14 from protruding and causing the connecting plate 3 to be unable to fit with the forming groove 1.

[0031] Example 2

[0032] Based on Embodiment 1, a preferred embodiment of the dust cover mold ejection structure provided by this utility model is, for example... Figures 1 to 5 As shown: A bracket 16 is fixedly connected to the bottom of the forming groove 1, a rubber pad 18 is fixedly connected to the bottom of the bracket 16, and a groove 17 is provided on the side of the bracket 16.

[0033] In this embodiment, the rubber pad 18 is made of non-slip rubber and completely covers the bottom of the bracket 16. By setting the rubber pad 18, the device as a whole can achieve shock absorption and anti-slip effect.

[0034] In this embodiment, the groove 17 is provided through the bracket 16. Under the action of the groove 17, it is convenient to transport the forming groove 1 through the groove 17, and avoid the bottom of the forming groove 1 being directly attached to the table surface, which makes it difficult to transport.

[0035] The working principle and usage process of this utility model are as follows: First, the motor 8 is turned on to control the first gear 9 to rotate, and the second gear 10 rotates accordingly, driving the positive and negative screws 11 to rotate. At this time, the two sets of transmission plates 12 will slide in opposite directions along the inside of the forming groove 1 when the positive and negative screws 11 rotate. When the two sets of transmission plates 12 approach each other, they will control the two sets of transmission rods 13 to also approach and slide along the inside of the connecting groove 15. Since the connecting groove 15 is in an inclined state, when the transmission rods 13 move, they will apply an upward pushing force to the ejector plate 14. When the ejector plate 14 moves upward, it will apply an upward pushing force to the force plate 5. The force plate 5 will then apply a pushing force to the connecting plate 3. Under the limit of the telescopic rod 2, the connecting plate 3 moves horizontally upward, and the mold body 4 will be ejected accordingly.

[0036] By setting the slide groove 7, the sealing plate 6 will not interfere with the positive and negative screws 11 when it is installed. When disassembling the sealing plate 6, the screws can be removed and the sealing plate 6 can be pushed upward. By setting the rubber pad 18, the whole equipment can be shock-absorbing and anti-slip. In addition, under the action of the groove 17, it is easy to move the forming groove 1 through the groove 17, avoiding the bottom of the forming groove 1 from being directly attached to the table surface, which makes it difficult to move.

[0037] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
