Abstract
Description
Technical Field
[0001] This utility model relates to the field of hump tube technology, specifically a hump tube forming mold structure. Background Technology
[0002] Hump pipes are a type of reducing pipe widely used in the automotive industry. The processing technology for hump pipes generally involves casting blanks, shot blasting the blanks, and machining. Existing hump pipe forming molds typically involve pouring liquid metal into the mold, and after the casting solidifies, a blank is obtained.
[0003] However, during the molding process, when demolding is required, ejection is typically used. After the casting solidifies inside the mold, the adhesion between the metal and the mold's inner wall often causes the mold to stick to the mold wall when demolded directly by ejection. This adhesion can cause tearing during demolding, affecting not only the product's appearance but also potentially reducing its mechanical properties and lifespan. Utility Model Content

The long plate moves up and down reciprocally, which can drive synchronous movement, thereby ejecting the formed hump tube.
[0010] Preferably, the inner wall of the groove is provided with a ratchet, the output shaft surface of the motor is provided with a pawl, the output shaft surface of the motor is provided with a pawl, and the inner side of the sprocket is connected to the ratchet, so that when the motor rotates forward, the sprocket will not rotate, and conversely, when the motor rotates in reverse, the fixed column will not rotate in reverse.

[0021] like Figures 1-5 As shown, this utility model provides a technical solution: a hump tube forming mold structure, including an operating table 1, a lower mold 7 slidably connected to the top of the operating table 1, a forming cavity opened on the top of the lower mold 7, and an active component 8 for preventing sticking and an ejection component 9 for easy demolding provided inside and on the surface of the operating table 1. The active component 8 includes: a stabilizing plate 80, a motor 81, a fixing column 82, a triangular plate 83, a concave plate 84, a contact rod 85, and a groove 86.
[0022] A stabilizing plate 80 is fixed to the top of the operating table 1. A motor 81 is fixed to the top of the operating table 1. A fixed column 82 is rotatably connected to the surface of the stabilizing plate 80. The movable component 8 also includes a groove 86, which is formed on the surface of the fixed column 82. A triangular plate 83 is fixed to the end of the fixed column 82 away from the motor 81. A concave plate 84 is fixed to the surface of the lower mold 7. An abutment rod 85 is fixed to the surface of the concave plate 84. Two sets of abutment rods 85 are provided, and both sets of abutment rods 85 are symmetrical about the center line of the concave plate 84. The two sets of abutting rods 85 are symmetrically arranged, with their surfaces abutting against the surfaces of the triangular plates 83. The output shaft of the motor 81 passes through the stabilizing plate 80, and the output shaft of the motor 81 is rotatably connected to the stabilizing plate 80. When the motor 81 is turned on and rotates forward, it drives the fixed column 82 and the triangular plate 83 to rotate through the ratchet and pawl. The surface of the triangular plate 83 abuts against the surface of the abutting rods 85, which drives the concave plate 84 and the lower mold 7 to reciprocate left and right. This avoids adhesion to the inner wall of the lower mold 7 and prevents tearing during subsequent ejection and demolding.
[0023] The ejector assembly 9 includes a first sprocket 90, which is rotatably connected to the surface of a stabilizing plate 80. A fixing plate 92 is fixed to the top of the inner wall of the operating table 1. A second sprocket 93 is rotatably connected to the surface of the fixing plate 92. A chain 91 is driven through the surfaces of the first sprocket 90 and the second sprocket 93. The chain 91 passes through the operating table 1. A long plate 94 is slidably connected to the inner wall of the operating table 1. A connecting plate 95 is fixed to the bottom of the long plate 94. A through hole 96 is opened on the surface of the connecting plate 95. A long rod 904 is fixed to the surface of the second sprocket 93. A circular plate 97 is fixed to the end of the long rod 904 away from the second sprocket 93. A short rod 98 is fixed to the side of the circular plate 97 away from the long rod 904. The end of the short rod 98 away from the circular plate 97 passes through the through hole 96, and the surface of the short rod 98 abuts against the inner wall of the through hole 96. The output shaft of the motor 81 passes through the first sprocket 90. A limit plate 900 is slidably connected to the top of the inner wall of the operating table 1. A spring 902 is fixed to the bottom of the position plate 900, and a base plate 99 is fixed to the bottom of the spring 902. The bottom of the base plate 99 is in contact with the top of the long plate 94. A movable hole 903 is opened on the surface of the operating table 1. A push rod 901 is fixed to the top of the base plate 99. The top of the push rod 901 passes through the limiting plate 900, the movable hole 903, and the lower mold 7. The push rod 901 is slidably connected to the lower mold 7 and the limiting plate 900. When the motor 81 is turned on and reversed, the sprocket 90 drives the chain 91 to drive the sprocket 93 to rotate synchronously through the ratchet 2 and the pawl 2. The long rod 904 drives the round plate 97 and the short rod 98 to rotate. The surface of the short rod 98 abuts against the inner wall of the through hole 96, which drives the connecting plate 95 and the long plate 94 to move up and down. When the long plate 94 moves up, the top of the long plate 94 abuts against the bottom of the base plate 99, which drives the push rod 901 to move up, thereby ejecting the formed hump tube for easy demolding.
[0024] The inner wall of the groove 86 is provided with a ratchet, the output shaft surface of the motor 81 is provided with a pawl, the output shaft surface of the motor 81 is provided with a pawl, and the inner side of the sprocket 90 is connected to the ratchet. When the motor 81 rotates forward, the sprocket 90 will not rotate, and conversely, when the motor 81 rotates in reverse, the fixed column 82 will not rotate in reverse.
[0025] A support rod 2 is fixed to the top of the operating table 1, a top plate 3 is fixed to the top of the support rod 2, a cylinder 4 is fixed to the top of the top plate 3, the output end of the cylinder 4 passes through the top plate 3, a slide plate 5 is fixed to the bottom of the output end of the cylinder 4, the slide plate 5 is passed through the support rod 2, and the slide plate 5 is slidably connected to the support rod 2. An upper mold 6 is fixed to the bottom of the slide plate 5. When the cylinder 4 is opened, the slide plate 5 drives the upper mold 6 to move down, so that the upper mold 6 and the lower mold 7 can be closed.
[0026] During processing, opening cylinder 4 causes slide plate 5 to move the upper mold 6 downwards, allowing the upper mold 6 to close with the lower mold 7. At this point, liquid can be injected into the molding cavity for molding. When demolding is required after cooling, opening cylinder 4 moves it upwards, separating the upper mold 6 from the lower mold 7. At this time, motor 81 rotates forward, driving the fixed post 82 to rotate via ratchet wheel 1 and pawl 1. Triangle plate 83 rotates, its surface contacting the contact rod 85, causing the concave plate 84 and lower mold 7 to reciprocate left and right, preventing adhesion to the inner wall of the lower mold 7. Then, motor 81 rotates in the reverse direction. When the chain is turned, the second ratchet and the second pawl cause the first sprocket 90 to rotate synchronously with the second sprocket 93 via the chain 91. At this time, the long rod 904 drives the round plate 97 and the short rod 98 to rotate synchronously. The surface of the short rod 98 abuts against the inner wall of the through hole 96, which drives the connecting plate 95 and the long plate 94 to move up and down reciprocally. When the long plate 94 moves up, the top of the long plate 94 abuts against the bottom of the base plate 99, which drives the push rod 901 to move up, thereby ejecting the formed hump tube. At the same time, the spring 902 is compressed. When the connecting plate 95 and the long plate 94 move down, the spring 902 is released, which drives the push rod 901 to reset, making it convenient for the next use.
[0027] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
