[0001] This utility model relates to the field of injection mold technology, specifically to a camera housing molding mold. Background Technology

[0002] With the booming development of industries such as security monitoring, smartphones, and smart cars, the market demand for cameras, as key components for acquiring image information, continues to grow. Camera housings not only protect the internal precision optical and electronic components but also affect the overall performance and appearance quality of the camera. As the core tool for producing camera housings, the design and manufacturing quality of camera housing molds directly determine the molding accuracy, production efficiency, and cost.

[0003] Existing devices have some drawbacks in use. For example, in traditional mold production, operations such as opening and closing the mold, ejecting the product, and picking up the material all need to be done manually by workers. When manually opening and closing the mold and picking up the material, there are certain safety risks, such as fingers being pinched by the mold or being hit by the ejected product. Utility Model Content

[0004] The purpose of this utility model is to provide a camera housing molding mold to solve the problem of certain safety risks when manually opening and closing the mold and picking up materials.

[0014] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Example

[0015] like Figures 1-4 As shown, this utility model provides a technical solution: a camera housing molding die, including a base 1, with columns 11 symmetrically fixed on both sides of the upper surface of the base 1, and a lower die 12 fixedly connected to the top of the two columns 11. A mounting bracket 13 is fixedly connected to one side of the upper surface of the base 1, and a first cylinder 14 is fixedly mounted on the top of the mounting bracket 13. The piston end of the first cylinder 14 is vertically downward and the end is fixedly connected to an upper die 15. The upper surface of the upper die 15 has an inlet 151 for introducing molten material. An ejection assembly 2 for ejecting the die is provided between the two columns 11. A material removal assembly 3 for removing the die is provided on the side of the upper surface of the base 1 away from the mounting bracket 13. In specific use, when the first cylinder 14 is activated, its piston end drives the upper die 15 to move vertically downward, connecting with the lower die 12. The mold closes precisely, forming a complete camera housing cavity. At this point, a sealed space is formed inside the mold. Molten plastic material is injected into the mold cavity through the feed port 151 using an injection molding machine. The material fills the entire cavity under high temperature and pressure and undergoes a cooling and solidification process to form the initial shape of the camera housing. After injection molding, the piston end of the first cylinder 14 retracts, causing the upper mold 15 to move upward and separate from the lower mold 12, exposing the formed camera housing. The ejector assembly 2 is activated to eject the formed camera housing from the lower mold 12, completely separating it from the mold. The material handling assembly 3 is activated to precisely position and grab the ejected camera housing, removing it from the mold area and placing it in a designated location or on a conveyor belt for subsequent quality inspection, trimming, or packaging processes.

[0016] As one implementation method in this embodiment, such as Figure 4As shown, the ejector assembly 2 includes a second cylinder 21 fixedly mounted on the upper surface of the base 1. A lifting plate 22 is fixedly connected to the piston end of the second cylinder 21. Ejector rods 23 are fixedly connected to both sides of the upper surface of the lifting plate 22. Two through holes 24 are opened in the cavity of the lower mold 12. The tops of both ejector rods 23 are inserted into the through holes 24. In actual use, after the camera housing has completely cooled and solidified in the mold cavity, the piston end of the first cylinder 14 begins to retract, driving the upper mold 15 upwards, separating the upper mold 15 from the lower mold 12, exposing the formed camera housing. At this time, the camera housing remains in the cavity of the lower mold 12. The second cylinder 21 then begins to work. The piston end of cylinder 21 extends upward, pushing the lifting plate 22, which is fixedly connected to it, to move upward. Since the upper end face of the lifting plate 22 is fixedly connected to the two sides of the push rod 23, and the top ends of the two push rods 23 are inserted into the through holes 24 opened in the mold cavity of the lower mold 12, the rise of the lifting plate 22 will drive the push rods 23 to move upward along the through holes 24. During the rise, the top end of the push rod 23 gradually contacts and applies an upward force to the bottom of the formed camera housing. As the push rod 23 continues to rise, the camera housing is smoothly pushed out of the mold cavity of the lower mold 12, so that it is completely separated from the lower mold 12. At this time, the camera housing is in a free state, which facilitates the subsequent material handling operation.

[0017] As one implementation method in this embodiment, such as Figure 1 As shown, the material handling assembly 3 includes a rotating base 31 rotatably connected to the upper surface of the base 1. An L-shaped support plate 32 is fixedly connected to the upper surface of the rotating base 31. An electric telescopic rod 33 is fixedly installed on the L-shaped support plate 32. A drive shaft 34 is fixedly connected to the movable end of the electric telescopic rod 33. A suction cup 35 for adsorbing molding material is fixedly connected to the bottom end of the drive shaft 34. A drive assembly 4 for driving the rotating base 31 to rotate is also provided on the upper surface of the base 1. In actual use, when the camera housing is pushed out, the drive assembly 4 is activated, driving the rotating base 31 to rotate around its axis. The rotating base 31 drives the L-shaped support plate 32, the electric telescopic rod 33, the drive shaft 34, and the suction cup 35 to rotate as a whole, so that the suction cup 35 accurately... Moved to directly above the ejected camera housing, the electric telescopic rod 33 begins to extend, and the drive shaft 34 drives the suction cup 35 to move downwards. The suction cup 35 gradually approaches the camera housing, and when it contacts the housing surface, the vacuum generator inside the suction cup 35 (or through an external vacuum pump) starts to work, creating a negative pressure between the suction cup 35 and the housing surface, thereby firmly adsorbing the camera housing onto the suction cup 35. After successful adsorption, the electric telescopic rod 33 retracts, driving the suction cup 35 with the adsorbed camera housing to rise upwards, so that the housing is completely separated from the lower mold 12. Subsequently, the drive assembly 4 drives the rotating chassis 31 to rotate again, moving the suction cup 35 with the adsorbed housing to the designated material release position, such as above a conveyor belt, quality inspection station, or storage container.

[0018] As one implementation method in this embodiment, such as Figure 1 As shown, the drive assembly 4 includes a limiting slide groove 41 formed on the upper surface of the base 1 and a third cylinder 42 fixed to the upper surface of the base 1. A limiting slider 43 is slidably connected in the limiting slide groove 41. A rack 44 is fixedly connected to the upper surface of the limiting slider 43. A drive gear 45 is fixedly sleeved on the outer wall of the rotating base 31. The drive gear 45 meshes with the rack 44 for transmission. A connecting rod 46 is fixedly connected to the outer wall of the rack 44. The piston end of the third cylinder 42 is fixed to the outer wall of the connecting rod 46. In specific use, when the mold is not performing a material removal operation, the third cylinder 42 is in the extended state. At this time, the piston end of the third cylinder 42 pulls the rack 44 through the connecting rod 46, so that the rack 44 slides in the limiting slide groove 41 towards the third cylinder 42 with the help of the limiting slider 43. Since the drive gear 45 meshes with the rack 44 for transmission, the movement of the rack 44 will drive the drive gear 45 to rotate, thereby causing the rotating base 31 to rotate to a set angle.

[0019] As one implementation method in this embodiment, such as Figure 3 As shown, guide grooves 51 are provided on the side walls of the two columns 11 near the lifting plate 22. Guide blocks 52 are slidably connected in the guide grooves 51. The ends of the two guide blocks 52 are fixed to the side walls of the lifting plate 22. In actual use, as the lifting plate 22 moves upward, the guide blocks 52 on both sides slide in a straight line along the guide grooves 51. The guide grooves 51 provide a precise movement trajectory for the guide blocks 52, restricting the lifting plate 22 to only move vertically, and avoiding horizontal deviation, swaying or twisting of the lifting plate 22 during the upward movement.

[0020] Working principle: In operation, the first cylinder 14 is activated, and its piston moves the upper mold 15 vertically downward, precisely closing with the lower mold 12 to form a complete camera housing molding cavity. At this time, a sealed space is formed inside the mold. Molten plastic raw material is injected into the mold cavity through the feed port 151 by the injection molding machine. The raw material fills the entire cavity under high temperature and pressure, and after cooling and solidification, forms the preliminary shape of the camera housing. After injection molding is completed, the piston of the first cylinder 14 retracts, moving the upper mold 15 upward and separating it from the lower mold 12, exposing the camera housing. After the camera housing is formed, the second cylinder 21 starts working. The piston end of the second cylinder 21 extends upward, pushing the lifting plate 22, which is fixedly connected to it, to move upward. Since push rods 23 are fixedly connected to both sides of the upper end face of the lifting plate 22, and the tops of both push rods 23 are inserted into the through holes 24 opened in the lower mold cavity 12, the rise of the lifting plate 22 will drive the push rods 23 to move upward along the through holes 24. During the rise, the tops of the push rods 23 gradually contact and apply an upward force to the bottom of the formed camera housing. As the cylinder continues to rise, the camera housing is smoothly ejected from the cavity of the lower mold 12, completely separating it from the lower mold 12. The piston end of the third cylinder 42 pulls the rack 44 through the connecting rod 46, causing the rack 44 to slide towards the third cylinder 42 within the limiting groove 41 by the limiting slider 43. Due to the meshing transmission between the drive gear 45 and the rack 44, the movement of the rack 44 drives the drive gear 45 to rotate, thereby causing the rotating base 31 to rotate to a set angle. The electric telescopic rod 33 begins to extend, and the drive shaft 34 drives the suction cup 35 to move downward. As the suction cup 35 gradually approaches the camera housing, when it touches the surface of the housing, the vacuum generator inside the suction cup 35 (or through an external vacuum pump) starts to work, creating a negative pressure between the suction cup 35 and the surface of the housing, thereby firmly adsorbing the camera housing onto the suction cup 35. After successful adsorption, the electric telescopic rod 33 retracts, driving the suction cup 35 with the camera housing adsorbed upwards, so that the housing is completely separated from the lower mold 12. Subsequently, the drive assembly 4 drives the rotating chassis 31 to rotate again, moving the suction cup 35 with the housing adsorbed to the designated material release position.

[0021] It should be noted that the first cylinder 14, the second cylinder 21, the third cylinder 42 and the electric telescopic rod 33 are all electrically connected to an external controller to achieve the effect of working together.

[0022] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
