Description

Technical Field

[0001] This utility model relates to the field of mold technology, specifically to a zinc alloy ingot production mold that facilitates demolding. Background Technology

[0002] A zinc alloy ingot production mold is a tool used to cast molten zinc alloy into ingots of a specific shape and size. It is usually made of metal material and has a cavity that matches the shape of the zinc alloy ingot. During the production process, molten zinc alloy is poured into the cavity of the mold, and after cooling and solidification, it forms the desired ingot. The design and manufacture of this mold need to take into account the characteristics of zinc alloy, such as fluidity, solidification speed and shrinkage rate, to ensure that the produced ingots are of high quality, dimensionally accurate and have a smooth surface. In the production of zinc alloy ingots, special molds are usually designed to facilitate demolding. However, during the demolding process, due to the high temperature of the zinc alloy ingots, workers cannot directly remove them from the mold by hand. If an external drive structure is used to assist in demolding, although the high temperature problem can be solved, this method can easily damage the surface of the zinc alloy ingot, thereby affecting its forming quality. Therefore, a zinc alloy ingot production mold that facilitates demolding is proposed to address the above problems. Utility Model Content

A first insert post 52 is fixedly connected to the top of the upper mold metal pad 51. A protrusion 53 is fixedly connected to the front end of the upper mold metal pad 51. A second post hole 54 is opened on the inner side of the protrusion 53. A second solenoid valve 55 is fixedly connected to the top of the protrusion 53. The lower mold assembly 6 includes a lower mold base 61. A lower mold metal pad 62 is tightly fitted to the top of the lower mold base 61. A protrusion plate 63 is fixedly connected to the front end of the lower mold metal pad 62. A second insert post 64 is fixedly connected to the top of the protrusion plate 63.

A drive structure is fixedly connected to the right side of the front plate 66.

[0018] As a further implementation of this solution, the bottom end of the top plate 1 is fixedly connected to the bottom plate 3 via a bracket, with an movable gap between the top plate 1 and the bottom plate 3. The top end of the top plate 1 is fixedly connected to the cylinder body of the electric hydraulic cylinder 2. A sliding hole is provided on the inner side of the top plate 1, and a guide rod 43 is slidably connected to the inner side of the sliding hole of the top plate 1. A pressure plate 41 is fixedly connected to the end of the piston rod of the electric hydraulic cylinder 2. Through the above configuration, this structural design not only provides a stable guiding effect for the piston rod and the slider guide rod 43, ensuring the accuracy and stability of the movement, but also provides the necessary space for the movement of the components through the setting of the movable gap, enhancing the overall flexibility and reliability of the device. As a further implementation of this solution, the bottom end of the guide rod 43 is fixedly connected to the side seat 42, the pressure plate 41 is fixedly connected to the side seat 42, the inner side of the pressure plate 41 is provided with a first column hole 44, and the top end of the pressure plate 41 is fixedly connected to a first solenoid valve 45. Through the above settings, this design forms a stable structure through the fixed connection between the guide rod 43 and the side seat 42, as well as the first column hole 44 on the inner side of the pressure plate 41 and the first solenoid valve 45 at the top end, which enhances the connection strength between the components and provides a basis for subsequent insertion and sealing operations, thereby improving the stability and sealing performance of the device. As a further implementation of this solution, the first post hole 44 is aligned vertically with the upper mold metal pad 51, and the opening diameter of the first post hole 44 matches the diameter of the first insert post 52. The first insert post 52 can be inserted into the inner side of the first post hole 44. Through the above settings, this alignment and size matching design ensures that the first insert post 52 can be accurately inserted into the inner side of the first post hole 44, realizing the fixing and disengagement between components, improving the assembly accuracy and working efficiency of the device, and also helping to ensure subsequent sealing and movement stability. As a further implementation of this solution, a rubber ring is fixedly connected to the outside of the first insertion post 52. The first insertion post 52 can be sealed with the inside of the first post hole 44 through the rubber ring. Through the above-mentioned arrangement, the rubber ring effectively enhances the sealing performance between the first insertion post 52 and the inside of the first post hole 44, prevents gas leakage, and improves the sealing performance and reliability of the device. As a further implementation of this solution, the shape of the upper end of the upper mold metal pad 51 matches the shape of the lower end of the pressure plate 41, and the shape of the lower end of the upper mold metal pad 51 matches the shape of the upper surface of the lower mold metal pad 62.

As a further implementation of this solution, the second insert 64 is vertically aligned with the second insert hole 54. The second insert 64 can be inserted into the interior of the second insert hole 54. The second insert 64 can be sealed with the second insert hole 54 by the rubber sealing ring 65. Through the above settings, this design further enhances the sealing performance and structural stability of the device by aligning and inserting the second insert 64 with the second insert hole 54 and sealing the second insert 64 with the second insert hole 54, thereby controlling the fixation and separation of the upper mold metal pad 51 and the lower mold metal pad 62. As a further implementation of this solution, the right side of the front plate 66 is fixedly connected to the end of the spindle of the servo motor 67. The housing of the servo motor 67 is fixedly connected to a support frame 68. The front plate 66 is rotatably connected to the inside of the support frame 68. The bottom end of the support frame 68 is fixedly connected to the base plate 3. Through the above configuration, this connection method not only achieves stable transmission between the front plate 66 and the servo motor 67, but also provides stable support for the entire rotation system through the fixed connection between the support frame 68 and the base plate 3, ensuring the smoothness and accuracy of the rotation. This stable rotation system can ensure the smooth release and unloading of zinc alloy ingots, avoid damage to zinc alloy ingots caused by unstable rotation, and further improve production efficiency and product quality.

[0019] Workflow: During the extrusion forming of zinc alloy ingots, the heated zinc alloy billet is placed into the groove of the lower die metal pad 62. Initially, the bottom end of the lower die metal pad 62 is in contact with the top end of the lower die base 61, and the shape of the lower end of the lower die metal pad 62 matches the shape of the upper part of the lower die base 61, which serves as a support. At the same time, the first inserts 52 are inserted into the first insert holes 44, and the multiple first solenoid valves 45 are in the closed state, while the second solenoid valves 55 are in the open state. The sealing effect of the rubber ring on the outside of the first inserts 52 can prevent... The upper die metal pad 51 is prevented from falling off from the pressure plate 41. The electric hydraulic cylinder 2 is activated to drive the upper die base assembly 4 and the upper die pad assembly 5 to move downward. The guide rod 43 slides inside the top plate 1 to guide the movement until the second insert 64 is inserted into the second insert hole 54. The second solenoid valve 55 is closed. The sealing of the rubber sealing ring 65 prevents the lower die metal pad 62 from separating from the upper die metal pad 51. When the bottom of the upper die metal pad 51 contacts the zinc alloy blank, the zinc alloy blank is extruded and formed. When cooling the formed zinc alloy billet, multiple first solenoid valves 45 are opened simultaneously, allowing external air to communicate with the inside of the first column hole 44. The electric hydraulic cylinder 2 is controlled to move upward, driving the upper mold base assembly 4 to move upward as a whole. Since the upper mold metal pad 51 and the lower mold metal pad 62 are in a positioning state, the upper mold pad assembly 5 will not move upward as a whole. The servo motor 67 is started to drive the front plate 66 and the lower mold metal pad 62 to rotate. At the same time, the lower mold metal pad 62 drives the upper mold metal pad 51 to rotate, so that the formed part between the upper mold metal pad 51 and the lower mold metal pad 62 is away from the lower mold base 61. Since the upper mold metal pad 51 and the lower mold metal pad 62 are relatively thin, the raised upper mold metal pad 51 and the lower mold metal pad 62 can be quickly cooled by a cold air blower. After cooling, the lower mold metal pad 62 and the upper mold metal pad 51 are reset, so that the lower mold metal pad 62 fits with the lower mold base 61. When unloading the zinc alloy ingot inside the lower die metal pad 62, the second solenoid valve 55 is opened. Following the same principle, the upper die base assembly 4 is controlled to move downward, allowing the first insert 52 to enter the first insert hole 44. The first solenoid valve 45 is then closed, and the electric hydraulic cylinder 2 is started to drive the upper die base assembly 4 and the upper die pad assembly 5 to move upward. The servo motor 67 is controlled to drive the front plate 66 and the lower die metal pad 62 to rotate. A rubber pad is laid at the front end of the base plate 3 until the lower die metal pad 62 rotates 180 degrees. At this time, the zinc alloy ingot inside the lower die metal pad 62 falls out. The rubber pad protects the zinc alloy ingot, thus achieving the unloading effect. Based on the above principles, when unloading the processed zinc alloy ingots, the device can first cool the zinc alloy ingots to prevent them from damaging external objects. At the same time, it can achieve automatic unloading without the need for external drive mechanism clamping or manual operation. This unloading method not only prevents injury to workers, but also significantly reduces the probability of scratches and damage during the unloading process of zinc alloy ingots, thereby improving production quality.
