Description

Technical Field

[0001] This utility model relates to the field of lamp housing die casting technology, specifically a lamp housing die casting mold that is easy to obtain materials from. Background Technology

[0002] Die casting is a metal casting process that uses high pressure to force molten metal into a metal mold cavity at high speed. After rapid cooling and solidification, a shaped casting is obtained. In the die casting production of lamp housings, the die casting mold is the key equipment for achieving mass production.

[0003] After die casting, the workpiece needs to be separated from the mold cavity. Since the structure of lamp housing often includes internal cavities, clips, and flanges, the fit between the casting and the mold cavity is relatively high after die casting. In addition, some deep cavity structures are prone to forming a vacuum adsorption effect, making it difficult for the casting to be removed from the mold. Operators need to use auxiliary tools such as pry bars and suction cups to remove the material, which not only increases the labor intensity, but also easily causes scratches and deformation on the surface of the casting due to improper operation, affecting the quality of the finished product.

[0030] Please see Figures 1-6 This utility model provides a technical solution: a convenient die-casting mold for lamp housing, including a first base 1, a second base 2, a fixed mold base 3, a moving mold base 4, a fixed mold cavity 5, a moving mold cavity 6, an electric push rod 7, a first injection port 8, a second injection port 9, a feeding cylinder 10, a liquid inlet pipe 11, a hydraulic cylinder 12, a top plate 13, a positioning rod 14, a first side plate 15, a first push rod 16, a first spring 17, a second side plate 18, a second push rod 19, a second spring 20, a drive rod 21, a receiving box 22, and a locking block 23.

[0031] A second base 2 is arranged parallel to one side of a first base 1. Support columns are respectively installed on the lower surfaces of both bases 1 and 2. A fixed mold base 3 is fixedly installed on the upper surface of the first base 1. A movable mold base 4 is aligned with the side surface of the fixed mold base 3 and slidably installed on the upper surface of the second base 2. A fixed mold cavity 5 is provided on the side surface of the fixed mold base 3, and a movable mold cavity 6 is provided on the side surface of the movable mold base 4. The fixed mold cavity 5 and the movable mold cavity 6 together constitute the cavity structure of the mold. The surface of the movable mold base 4 is fixedly connected to the output end of an electric push rod 7, which is fixedly installed on the upper surface of the second base 2. A feeding structure is provided below the cavity structure. The feeding structure realizes the process of molten raw material entering the cavity structure through a first injection port 8 and a second injection port 9. It includes a first injection port 8, which is embedded and fixed on the side surface of the fixed mold base 3. The first injection port 8 has a hollow structure. A second injection port 9 is provided on one side of the first injection port 8. The second injection port 9 is embedded and fixed on the side surface of the moving mold base 4. The upper ends of the first injection port 8 and the second injection port 9 are respectively connected to the fixed mold cavity 5 and the moving mold cavity 6. The first injection port 8 and the second injection port 9 are engaged and matched. The first injection port 8 is connected to the feeding cylinder 10.

[0032] like Figure 1 , Figure 2 and Figure 4 As shown, when using this device to die-cast the lamp housing, the electric push rod 7 is activated. The electric push rod 7 causes the moving mold base 4 to slide along the upper surface of the second base 2 towards the fixed mold base 3. At the same time, the moving mold base 4 slides on the surface of the positioning rod 14 to ensure precise alignment between the moving mold base 4 and the fixed mold base 3. When the moving mold base 4 and the fixed mold base 3 are in contact, the fixed mold cavity 5 on the side surface of the fixed mold base 3 and the moving mold cavity 6 on the side surface of the moving mold base 4 together form a closed cavity structure. At the same time, the first injection port 8 on the fixed mold base 3 and the second injection port 8 on the moving mold base 4... The injection port 9 engages and matches to form a complete feeding channel, completing the mold closing. Molten material is injected into the feeding cylinder 10 through the liquid inlet pipe 11 on the upper surface of the feeding cylinder 10. The hydraulic cylinder 12 fixed on the upper surface of the first base 1 is activated, and its output end slides along the inner side of the feeding cylinder 10, pushing the molten material in the feeding cylinder 10 through the feeding channel formed by the first injection port 8 and the second injection port 9, and evenly injecting it into the cavity structure formed by the fixed mold cavity 5 and the moving mold cavity 6. After the molten material cools and solidifies in the cavity, the die casting process is completed.

[0033] A top plate 13 is fixedly mounted on the upper surface of the first base 1 via a bracket. A positioning rod 14 is provided on the lower surface of the top plate 13. One end of the positioning rod 14 is fixedly connected to the upper surface of the fixed mold base 3, and the other end of the positioning rod 14 is slidably mounted on the upper surface of the moving mold base 4. Ejection and demolding structures are respectively provided on the side surfaces of the fixed mold base 3 and the moving mold base 4. The ejection and demolding structures are assisted by a first ejector rod 16 and a second ejector rod 19 to eject and demold the mold. The ejection and demolding structures include a first side plate 15 and a second side plate 18. The first side plate 15 is fixedly mounted on the lower surface of the top plate 13. A first ejector rod 16 slides through the surface of the first side plate 15. One end of the first ejector rod 16 passes through the surface of the fixed mold base 3 and inserts into the fixed mold cavity 5. A first spring 17 is provided on the outer surface of the first ejector rod 16. One end of the first spring 17 is fixed to the surface of the first side plate 15. The other end is fixed to the surface of the first push rod 16. The second side plate 18 is fixedly installed on the upper surface of the second base 2. The second side plate 18 is in sliding contact with the output end of the electric push rod 7. The surface of the second side plate 18 is fixedly installed with a drive rod 21. The second push rod 19 is aligned with one side of the drive rod 21. One end of the second push rod 19 slides through the surface of the moving mold base 4 and is inserted into the moving mold cavity 6. The outer surface of the second push rod 19 is provided with a second spring 20. One end of the second spring 20 is fixed to the second push rod 19, and the other end of the second spring 20 is fixed to the moving mold base 4. The bottom of the first base 1 and the second base 2 is provided with a receiving box 22. The receiving box 22 is an open structure with a high center and low sides. The upper surface of the receiving box 22 is symmetrically fixed with two T-shaped locking blocks 23. The two locking blocks 23 are slidably engaged with the lower surfaces of the first base 1 and the second base 2, respectively.

[0034] like Figure 3 , Figure 5 and Figure 6 As shown, after die casting, the electric push rod 7 is activated again. The electric push rod 7 causes the moving mold base 4 to slide in the opposite direction and separate from the fixed mold base 3. At this time, for the fixed mold base 3 side, the first ejector rod 16 on the surface of the first side plate 15 loses the pressure of the molten material inside the cavity after the mold is opened. The first spring 17 on the surface ignites, driving the first ejector rod 16 to extend into the fixed mold cavity 5, ejecting the workpiece remaining in the fixed mold cavity 5. The ejected workpiece falls into the receiving box 22 below the first base 1 and the second base 2 under the action of gravity. Similarly, for the moving mold base 4 side, as the moving mold... The base 4 is away from the fixed mold base 3. The second side plate 18 fixed on the upper surface of the second base 2 is close to the moving mold base 4. The drive rod 21 on the surface of the side plate contacts the second ejector rod 19 on the moving mold base 4 and pushes it to slide, so that the second ejector rod 19 extends into the moving mold cavity 6 and pushes the workpiece out of the moving mold cavity 6. The ejected workpiece also falls into the receiving box 22 below the first base 1 and the second base 2 under the action of gravity. The receiving box 22 slides and engages with the lower surface of the base through the T-shaped card block 23 on the upper surface. After collection, the receiving box 22 can be pulled out directly to transfer the workpiece.

[0035] Working principle: When using this convenient lamp housing die-casting mold, the electric push rod 7 is used to achieve the contact between the moving mold base 4 and the fixed mold base 3, so that the fixed mold cavity 5 and the moving mold cavity 6 form a closed cavity. The molten raw material enters the feeding cylinder 10 through the liquid inlet pipe 11, and the hydraulic cylinder 12 pushes the raw material into the cavity for die casting. After the molding is completed, the electric push rod 7 separates the moving mold base 4 from the fixed mold base 3, and the molded workpiece is pushed outward by the first ejector rod 16 and the second ejector rod 19. The ejected workpiece falls into the receiving box 22 under the base, which increases the overall practicality.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
