Description

TECHNICAL FIELD

[0001] The utility model relates to foundry technology field, concretely to a forming device of large -scale aluminum alloy die casting. BACKGROUND

[0002] The die casting die is a tool for casting metal parts, and is a tool for completing the die casting process on a dedicated die casting forging machine. The basic process of die casting is as follows: the metal liquid is first cast into the cavity of the die at low or high speed, and the die has a movable cavity surface which is pressed and forged during the cooling process of the metal liquid, thereby eliminating the shrinkage hole and shrinkage porosity defects of the blank and making the internal structure of the blank reach the broken grain of the forged state, and the comprehensive mechanical properties of the blank are significantly improved.

[0003] To this end, Chinese patent number CN202322220455.1 discloses a die casting die for thin-walled aluminum alloy die casting, which includes a bottom plate having a recess formed therein, two support columns fixedly connected to the upper surface of the bottom plate, a horizontal plate fixedly connected to the upper surface of the support columns, an upper die disposed below the horizontal plate, a lower die connected to the upper surface of the bottom plate in the middle, and a cavity formed in the middle of the upper die and the lower die. The die casting die for thin-walled aluminum alloy die casting is provided, which uses an exhaust valve to exhaust the gas inside the cavity through an exhaust pipe, making it easier for the die inside the cavity to form. The formed die is extended and retracted by the hydraulic cylinder below, and the push plate is uniformly stressed by the equalizing block, pushing out the formed die, avoiding direct insertion by the worker, and preventing the worker from being injured by the excess heat above. At the same time, uniform stress also prevents the die from being damaged due to uneven stress when being pushed out.

[0004] The device can push the formed product to the upper side of the lower die through the cooperation of the push plate and the hydraulic cylinder, but the product is still located on the lower side of the upper die and is blocked by the two support columns, and the space around is relatively small, leaving no room for movement, which makes it inconvenient for the worker to remove the product from the device, affecting the subsequent operation and processing of the product.

[0005] Therefore, in order to solve the above problems, a forming device for large-scale aluminum alloy die casting is proposed. UTILITY MODEL CONTENTS

Their principles and connection methods are existing technologies well known to those skilled in the art, so they will not be described in detail here.

[0025] A forming device for large aluminum alloy die castings includes: a base 1, a bracket 11 mounted on the top surface of the base 1, an electric telescopic rod 12 mounted on the top surface of the bracket 11, an upper mold 13 fixedly connected to the extended end of the electric telescopic rod 12, a feed pipe 14 mounted on the top surface of the upper mold 13, and a lower mold 15 mounted on the top surface of the base 1.

[0026] A feeding structure 2 is installed on the base 1. The feeding structure 2 includes a hydraulic cylinder 21, which is fixedly installed inside the base 1. A push plate 22 is fixedly connected to the extended end of the hydraulic cylinder 21. Two sets of support frames 23 are fixedly installed on the top surface of the base 1. The two sets of support frames 23 are respectively installed on the left and right sides of the lower mold 15. A guide rod 24 is fixedly connected to the top of the right set of support frames 23, and a threaded rod 25 is rotatably connected to the top of the left set of support frames 23. A motor 2 is fixedly installed at the top of the left set of support frames 23. 6. A movable plate 27 is slidably installed on the outer side of the guide rod 24. A fixed frame 28 is fixedly installed on the front side of the top of the base 1. A roller 29 is rotatably connected to the top surface of the fixed frame 28. The rotation of the threaded rod 25 can drive the movable plate 27 to move from back to front on the top surface of the lower mold 15. This can push the product lifted from the lower mold 15 to the front of the device, which is convenient for cooling the product and does not affect the continued use of the lower mold 15 and the upper mold 13. At the same time, it is convenient for workers to easily remove the product from the device, ensuring the practicality of the device.

[0027] Furthermore, a shielding structure 3 is installed on the upper mold 13. The shielding structure 3 includes a fixing rod 31, which is fixedly installed on the top surface of the upper mold 13. A limiting rod 32 is inserted into the top of the fixing rod 31, and a shielding plate 33 is fixedly connected to the end of the limiting rod 32. The shielding plate 33 shields the upper side of the feed pipe 14 to prevent debris in the environment from entering the upper mold 13 and the lower mold 15 and affecting the quality of the product.

[0028] Furthermore, the push plate 22 is located inside the lower mold 15, and the output end of the motor 26 is fixedly connected to the rear end of the threaded rod 25. The push plate 22 can push the product inside the lower mold 15 upward, and the motor 26 provides power for the rotation of the threaded rod 25.

[0029] Furthermore, the threaded rod 25 is threadedly connected to the movable plate 27. The bottom surface of the movable plate 27 is flush with the top surface of the lower mold 15. The movable plate 27 is located on the rear side of the lower mold 15. The rotation of the threaded rod 25 can drive the movable plate 27 to slide on the guide rod 24, so as to push the product on the top surface of the lower mold 15 forward.

[0030] Furthermore, the fixing frame 28 is located on the front side of the lower mold 15, and the top surface of the roller 29 is flush with the top surface of the lower mold 15. The movement of the product on the fixing frame 28 can be reduced by the roller 29.

[0031] Furthermore, the limiting rod 32 is rectangular, and the cover plate 33 covers the upper side of the feed pipe 14. The setting of the limiting rod 32 prevents the cover plate 33 from rotating.

[0032] Working principle: The shield 33 blocks the upper side of the feed pipe 14 to prevent environmental debris from entering the upper mold 13 and lower mold 15 and affecting the quality of the product. When in use, the electric telescopic rod 12 is activated, which can drive the upper mold 13 to descend and fit against the lower mold 15. Pulling the shield 33 causes the limiting rod 32 to move on the fixed rod 31, which can move the shield 33 away from the upper side of the feed pipe 14. Raw materials can be added to the inside of the lower mold 15 and the upper mold 13 through the feed pipe 14.

[0033] After the product is formed, the electric telescopic rod 12 is controlled to lift the upper mold 13 upwards, moving it away from the lower mold 15. The hydraulic cylinder 21 is activated, causing the push plate 22 to rise. The push plate 22 pushes the product upwards from the lower mold 15, allowing the product to move to the top surface of the lower mold 15. The motor 26 is then activated, driving the threaded rod 25 to rotate. The threaded rod 25 is threadedly connected to the movable plate 27. The rotation of the threaded rod 25 causes the movable plate 27 to slide forward on the guide rod 24. As the movable plate 27 moves, it can conform to the rear wall of the product and push the product forward, allowing it to... The product is moved to the fixed frame 28 via the top surface of the push plate 22. The roller 29 on the fixed frame 28 can fit against the bottom surface of the product and roll on the bottom surface of the product when it moves, which can reduce the friction between the product and the fixed frame 28 to keep the product intact. The product can be moved to the front of the upper mold 13 and the lower mold 15 without obstructing the upper mold 13 and the lower mold 15, so that the die casting material can continue. The product can be cooled at the front of the device to reduce residual temperature. At the same time, when the operator removes the product, he will not be obstructed by the device and can operate in a spacious area, ensuring the convenience of operation.
