Description

Technical Field

[0001] The invention relates to the technical field of sealing ring processing, in particular to a vulcanizing device for producing engine sealing rings. Background Art

[0002] The engine seal is an important component used to seal the internal fluid of the engine (such as lubricating oil or coolant). It is usually made of plastic and is used to form a seal at various joints or seams of the engine to prevent fluid leakage.

[0003] The sealing ring of the engine is usually formed and vulcanized in a vulcanizer, and the obtained sealing ring has good heat resistance and chemical resistance. The existing sealing ring vulcanizer is mainly composed of a machine body, a guide rail, an upper mold, a lower mold, and a mechanism for controlling the upper mold and the lower mold to move, close the mold, and separate the molds. During operation, the sealing ring raw material strips need to be manually placed on the lower mold in an orderly manner, and then the mold is closed for molding and vulcanization operations, so that the molded sealing ring is more uniform. During the separation, the sealing ring and the waste material will adhere to the surface of the upper mold. At this time, the sealing ring and the waste material will be connected together, and then the sealing ring can be obtained by taking out and cutting off the waste material.

[0004] However, when they are manually placed in an orderly manner, deviations are likely to occur, which will affect the uniformity of the formed sealing ring. At the same time, when the sealing ring and waste materials adhering to the surface of the upper mold are manually removed later, the upper mold, the sealing ring, and the waste materials will be exposed to high temperatures during the molding and vulcanization process, which can easily cause burns and inconvenience.

[0026] 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.

[0027] Example 1: Please refer to Figure 1-Figure 7 In the figure, a vulcanizing device for producing engine sealing rings includes a vulcanizer body 4, a guide frame 5 slidably mounted on the vulcanizer body 4, a lower mold 2 slidably mounted on the guide frame 5, and an upper mold 3 hinged on the lower mold 2. A connecting plate 6 is installed above the guide frame 5 through a telescopic mechanism. The connecting plate 6 is close to the lower mold 2, and a square frame 15 is symmetrically fixedly connected to the lower edge of one side wall of the connecting plate 6. The inner sides of the two square frames 15 are jointly fitted with a plurality of groups of positioning rods 16 arranged in an array, and the number of each group of positioning rods 16 is two. Elastic components are respectively provided between the plurality of groups of positioning rods 16 and the two square frames 15, and lifting components are provided between the two square frames 15 and the connecting plate 6. A lifting mechanism is provided on the side wall of the connecting plate 6.

[0028] The telescopic mechanism includes an external frame 1, which is fixedly connected to the end of the guide frame 5, and an electric push rod 7 is symmetrically fixedly installed on the upper end of the external frame 1, and the telescopic shaft ends of the two electric push rods 7 are fixedly connected to the other side wall of the connecting plate 6; specifically, when the two electric push rods 7 are started, the two electric push rods 7 can drive the connecting plate 6 to move away from the vulcanizer body 4, and vice versa.

[0029] The lifting assembly includes a U-shaped plate 22, which is fixedly connected to the outer wall of the square frame 15 near the connecting plate 6, and an electric push rod 23 is provided at the upper end of the U-shaped plate 22. The outer wall of the electric push rod 23 is fixedly sleeved with a U-shaped block 24, one end of the U-shaped block 24 is fixedly connected to the side wall of the connecting plate 6, and the telescopic shaft end of the electric push rod 23 is fixedly connected to the upper end of the U-shaped block 24; specifically, starting the electric push rod 23 can drive the U-shaped block 24 to move upward, and the square frame 15 moves upward accordingly, which is convenient for controlling the height of the square frame 15.

[0030] The elastic component includes two fixed blocks 20, which are symmetrically fixedly connected to the outer wall of the frame 15, and the inner walls of the two fixed blocks 20 are slidably interspersed with sliding columns 33, the corresponding ends of the two sliding columns 33 are respectively fixedly connected to the wall surfaces away from the two positioning rods 16, and the ends of the two sliding columns 33 away from each other are fixedly connected to the limiting plates 21, and the two limiting plates 21 are respectively fixedly connected to the wall surfaces away from the two fixed blocks 20, and the outer walls of the two sliding columns 33 are slidably sleeved with springs 26, and the springs 26 are fixedly connected between the positioning rods 16 and the fixed blocks 20.

[0031] Fixed plates 18 are symmetrically provided on the top of the multiple groups of positioning rods 16. The multiple fixed plates 18 located in the front and the multiple fixed plates 18 located in the rear are connected to the side walls of the connecting plate 6 through connecting components, and both ends of the multiple fixed plates 18 located in the front and the multiple fixed plates 18 located in the rear are fitted with inclined plates 19. The bottom ends of the multiple inclined plates 19 located in the front are respectively fixedly connected to the front edges of the upper ends of the multiple positioning rods 16, and the bottom ends of the multiple inclined plates 19 located in the rear are respectively fixedly connected to the rear edges of the upper ends of the multiple positioning rods 16.

[0032] The connecting assembly includes a support plate 14, which is fixedly connected to the side wall of the connecting plate 6 near the upper edge, and the lower end of the support plate 14 is fixedly connected to multiple fixing columns 17, and the bottom ends of the multiple fixing columns 17 are respectively fixedly connected to the upper ends of multiple fixing plates 18; specifically, by setting the support plate 14 and the fixing columns 17, it is convenient to support the fixing plate 18.

[0033] In this embodiment, combined with Figure 2, the raw material strips of the sealing ring of the engine can be placed respectively between the two closest positioning rods 16, and the raw material strips are attached between the two closest positioning rods 16, thereby assisting the raw material strips to be placed in an orderly manner on the lower mold 2, avoiding deviation in placement and affecting the uniformity of the sealing ring after subsequent molding. Then, the connecting plate 6 can be driven to move away from the vulcanizer body 4 through the telescopic mechanism, so that the multiple groups of positioning rods 16 connected to the connecting plate 6 and other components connected to the connecting plate 6 leave the lower mold 2, avoiding affecting the mold closing between the lower mold 2 and the upper mold 3.

[0034] Then, the lower mold 2 and the upper mold 3 can be controlled by the guide rail frame 5 to move toward the inside of the vulcanizer body 4, and the lower mold 2 and the upper mold 3 will be molded together, and finally the sealing ring is formed and vulcanized. This is a well-known existing technology and will not be described in detail.

[0035] It should be noted that when the lower mold 2 moves, it will drive the raw material strip to move together. In order to avoid that the positioning rod 16 hinders the movement of the raw material strip, before the lower mold 2 enters the inner side of the vulcanizer body 4, the two boxes 15 can be driven to move upward by the lifting assembly, and then the multiple groups of positioning rods 16 will move upward accordingly, and the inclined plates 19 on the multiple groups of positioning rods 16 will also move upward. At this time, the inclined plates 19 at both ends of each fixed plate 18 will move away from each other, and the wall surface of the inclined plate 19 and the end of the fixed plate 18 will always keep sliding, then the two adjacent positioning rods 16 at each location will move away from each other, each positioning rod 16 will drive the sliding column 33 connected to it to slide in the corresponding fixed block 20, and each positioning rod 16 will squeeze the spring 26 connected to the fixed block 20 until the bottom ends of the multiple groups of positioning rods 16 are higher than the upper end surface of the raw material strip. At this time, the movement of the raw material strip is not affected by the positioning rod 16.

[0036] It should also be noted that the two adjacent positioning rods 16 at each location will move away from each other during the upward movement, so as to avoid the friction between the positioning rods 16 and the raw material strips when the two positioning rods 16 move upward, causing the raw material strips to be lifted up, causing the position of the raw material strips to change, thereby avoiding affecting the positioning effect of the positioning rods 16 on the raw material strips.

[0037] Example 2: Please refer to Figure 2 , Figure 4 , Figure 6 and Figure 7 This embodiment further explains Example 1. The material-lifting mechanism includes an air pump 9 and two shovel blades 10. The air outlet end of the air pump 9 is connected to an air pipe 11. The front and rear parts of the outer wall of the air pipe 11 are symmetrically connected to air outlet pipes 25. The four air outlet pipes 25 are fixedly passed through the inner wall of the connecting plate 6. The two shovel blades 10 are symmetrically fixedly connected to the side wall of the connecting plate 6. A clamping mechanism is provided between the air pipe 11 and the two shovel blades 10.

[0038] The material lifting mechanism also includes a fixing ring 8, which is fixedly connected to the side wall of the connecting plate 6 near the rear edge, and the inner wall of the fixing ring 8 is fixedly connected to the outer wall of the air pump 9. The two shovel blades 10 are located between the two square frames 15, and the bottom ends of the two shovel blades 10 are both in contact with the upper end of the lower mold 2. The two air outlet pipes 25 located in the front and the two air outlet pipes 25 located in the rear are respectively located above the two shovel blades 10.

[0039] The clamping mechanism includes an L-shaped tube 12, which is connected to the middle part of the outer wall of the air supply pipe 11. The end of the L-shaped tube 12 away from the air supply pipe 11 is connected to a splicing tube 13, and the outer walls of the splicing tube 13 are respectively connected to connecting tubes 27 corresponding to the two shovel blades 10. The middle parts of the inner walls of the two connecting tubes 27 are fitted with rubber blocks 31, and the lower edges of the inner walls of the two connecting tubes 27 are fixedly connected to fixed plates 32. The lower ends of the two rubber blocks 31 are fixedly connected to connecting columns 30, and the two connecting columns 30 are respectively movably inserted through the lower ends of the two fixed plates 32, and the bottom ends of the two connecting columns 30 are fixedly connected to clamps 28, and the outer walls of the two connecting columns 30 are slidably sleeved with springs 29, and the springs 29 are fixedly connected between the rubber blocks 31 and the fixed plates 32.

[0040] In this embodiment, after the lower mold 2 and the upper mold 3 are moved outward from the inner side of the vulcanizer body 4 on the guide rail frame 5 and after the mold is separated, the molded sealing ring and the waste material connected to the molded sealing ring will adhere to the lower mold 2. At this time, the connecting plate 6 is driven by the telescopic mechanism to move toward the vulcanizer body 4 until the parts connected to the connecting plate 6 are in the following state. Figure 2 The location shown in .

[0041] During the movement of the connecting plate 6, the two shovel blades 10 will be driven to shovel up the edges of the waste material around the formed sealing ring. Figure 2 It can be seen from the figure that the shovel blade 10 is in an inclined state, which can not only scoop up the edge of the waste material, but also the scooped waste material can be placed on the upper surface of the shovel blade 10 to a certain extent. At this time, the air pump 9 is started, and the air pump 9 can deliver air along the air delivery pipe 11 and the inside of the two air outlet pipes 25 to the upper surfaces of the two shovel blades 10. At the same time, the air pump 9 can also deliver air along the L-shaped pipe 12 and the splicing pipe 13 to the inside of the two connecting pipes 27 respectively. The elastic force of the spring 29 inside the two connecting pipes 27 is less than the air pressure, so the air pressure can push the rubber block 31 to slide downward, and the rubber block 31 can drive the connecting column 30 to slide downward in the fixed plate 32, and the connecting column 30 can also drive the clamping plate 28 to move downward until the clamping plate 28 is in close contact with the waste material placed on the upper surface of the shovel blade 10, and the two clamping plates 28 can clamp the waste material on the upper surfaces of the two shovel blades 10 to a certain extent.

[0042] The air discharged along the two air outlet pipes 25 can drill into the bottom of the scooped waste material, so that the molding sealing ring and other parts of the waste material can be continuously blown up and separated from the lower mold 2. At this time, under the clamping effect of the two clamping plates 28 on the edges of the waste material, the blown molding sealing ring and the waste material are not easily blown away from the lower mold 2 and fall off. At the same time, the blown air can accelerate the cooling of the lower mold 2.

[0043] Then the air pump 9 is turned off, and the two clamping plates 28 are moved up and reset under the action of the spring 29. Then the connecting plate 6 is moved away from the vulcanizer body 4 through the telescopic mechanism, and the parts connected to the connecting plate 6 will leave the top of the lower mold 2, so that it is convenient to remove the formed sealing ring and the waste material connected to the formed sealing ring without scalding, which brings convenience.
