Description

Technical Field

[0001] This utility model relates to the field of plastic mold technology, and in particular to the core structure of a mold for forming a vehicle camera bracket. Background Technology

[0002] Cameras are essential auxiliary tools on vehicles, mostly fixed to the chassis via brackets. During the molding process of these brackets, to ensure the mechanical strength of their positioning structures, the parting surface is generally located near the assembly surface. This allows the positioning structures, such as clips, to be formed entirely within a single cavity, preventing internal defects from remaining in the functional structure. However, this also makes demolding irregularly shaped structures, such as protective covers used to enclose the camera, difficult. Therefore, many camera protection structures on brackets are later fixed using locking devices or adhesive, resulting in cumbersome assembly and susceptibility to defects caused by human error. Utility Model Content

[0003] To address the problems existing in the prior art, this utility model provides a core structure for a vehicle camera bracket molding die, comprising a first side core, a second side core, a third side core, and a fourth side core. A single mold closing action can form a protective shell and multiple positioning buckle structures on different ends and side walls of the product. The product requires no subsequent secondary processing, has stable quality, and low production costs.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] The core structure of a vehicle-mounted camera bracket molding die includes a sprue plate, an A-plate, a fixed mold core, a moving mold core, a B-plate, and an ejector plate. Limiting mechanisms are provided between the sprue plate and the A-plate, and between the A-plate and the B-plate. The moving mold core and the fixed mold core are matched and interlocked, forming a cavity between them. The ejector plate has several ejector pins that can extend into the cavity. A first cavity is formed on the fixed mold core, and a second cavity adapted to the first cavity is formed on the moving mold core. The core structure includes a first side core, a second side core, a third side core, and a fourth core. The first side core is located beside the first cavity, and the second, third, and fourth side cores are all located beside the second cavity.

[0006] One end of the first side core is adapted to the product, and the other end extends obliquely to the outside of the fixed mold core and is connected to the A plate through the first core-pulling component. The first core-pulling component can push the first side core closer to or away from the first cavity.

[0007] The second and third side cores are respectively located on two opposite sides of the second cavity. One end of each side core is adapted to one side wall of the product, and the other end of each side core passes through the moving mold core and is slidably connected to the B plate. The second and third side cores are respectively connected to the B plate through a second core-pulling component. Each second core-pulling component can push the second or third side core closer to or away from the second cavity.

[0008] The fourth core is located on the other side of the second cavity, with one end adapted to the product and the other end connected to a plurality of ejector pins. The plurality of ejector pins can push the product away from the second cavity.

[0009] As a further explanation of the above technical solution:

[0010] In the above technical solution, the first core-pulling component includes a slide block, a slider, and an inclined push block: the slide block is disposed on the A plate, and a first inclined slide rail is provided on its side wall facing the fixed mold core; the slider is disposed on the sprue plate, one end of which passes through the A plate and extends to the slide block, and an inclined second slide rail is provided on the side wall facing the fixed mold core; the inclined push block is mounted on the second slide rail and can slide along it, and the other side wall of the inclined push block is matched and mounted on the first slide rail and can slide along it, and the inclined push block is detachably fixed to the first side core.

[0011] In the above technical solution, each of the second core-pulling components includes a push plate and a diagonal brace. One end of each push plate is detachably fixed to a second or third side core, and the other end is slidably connected to the B plate. Each diagonal brace is inclined and slidably mounted on a push plate, with one end extending to the outside of the B plate, and can be slidably connected to the A plate during mold closing to push the push plate to slide on the B plate.

[0012] In the above technical solution, the B plate is provided with a third slide that is adapted to each of the plurality of push plates.

[0013] In the above technical solution, the A plate is also provided with a number of guide plates that are adapted to the diagonal braces one by one. Each guide plate is a Z-shaped structure, with one end of each guide plate located on the A plate and having an oblique hole adapted to one of the diagonal braces.

[0023] like Figure 1As shown, the core structure of the vehicle camera bracket molding mold includes a sprue plate, an A-plate, a fixed mold core, a moving mold core 10, a B-plate 20, and an ejector plate. Limiting mechanisms are provided between the sprue plate and the A-plate, and between the A-plate and the B-plate 20. The moving mold core 10 and the fixed mold core are matched and engaged, forming a cavity between them. The ejector plate has several ejector pins 30 that can extend into the cavity. A first cavity is formed on the fixed mold core, and a second cavity adapted to the first cavity is formed on the moving mold core. The core structure includes a first side core 40, a second side core 50, a third side core 60, and a fourth core 70. The first side core 40 is located beside the first cavity, and the second side core 50, the third side core 60, and the fourth core 70 are all located beside the second cavity.

[0024] One end of the first side core 40 is adapted to the product, and the other end extends obliquely to the outside of the fixed mold core. It is connected to the A plate through the first core-pulling component 80. The first core-pulling component 80 can push the first side core 40 closer to or away from the first cavity.

[0025] The second side core 50 and the third side core 60 are respectively located on two opposite sides of the second cavity. One end of each side core 50 is adapted to one side wall of the product, and the other end of each side core 60 passes through the moving mold core 10 and is slidably connected to the B plate 20. The second side core 50 and the third side core 60 are respectively connected to the B plate 20 through a second core-pulling member 90. Each second core-pulling member 90 can push the second side core 50 or the third side core 60 closer to or away from the second cavity.

[0026] The fourth core 70 is located on the other side of the second cavity. One end of the core is adapted to the product, and the other end is connected to a number of ejector pins 30. The ejector pins 30 can push the product out of the second cavity.

[0027] When the mold is closed, the first core-pulling component 80 pushes the first side core 40, the second core-pulling component 90 pushes the second side core 50 and the third side core into the cavity; when the mold is opened, under the action of the limiting mechanism, the A plate and the sprue plate, and the B plate 20 and the A plate open one after another, the first side core 40, the second side core 50 and the third side core are pulled out of the cavity one after another, and finally the ejector pin 30 pushes the fourth core 70 to push the product out of the cavity.

[0028] It is common knowledge among those skilled in the art that plastic molds can be opened in stages under the action of a limiting mechanism, and the specific structure of the limiting mechanism will not be described in detail here.

[0029] like Figure 2As shown, the first core-pulling component 80 includes a slide block 81, a slider 82, and an inclined push block 83: the slide block 81 is disposed on plate A, and its side wall facing the fixed mold core has an inclined first slide rail 1 extending therefrom; the slider 82 is disposed on the sprue plate, one end of which passes through plate A and extends to the slide block 81, and the side wall of the slider 82 facing the fixed mold core has an inclined second slide rail 2; the inclined push block 83 is mounted on the second slide rail 2 and can slide along it, and the other side wall of the inclined push block 83 is matched and mounted on the first slide rail 1 and can slide along it, and the inclined push block 83 is detachably fixed to the first side core 40.

[0030] In this embodiment, the first side core 40 is used to form a protective shell structure with one end of the product tilted. During mold closing, the moving mold pushes plate A against the sprue plate, slide block 81 and slider 82 move towards each other, and the inclined push block 83 slides on the first slide rail 1 and the second slide rail 2 and approaches the fixed mold core, pushing the first side core 40 into the first cavity. In the first stage of mold opening, plate A and the sprue plate are pulled apart, slide block 81 and slider 82 move away from each other, and the inclined push block 83 slides on the first slide rail 1 and the second slide rail 2 and moves away from the fixed mold core, pulling the first side core 40 out of the first cavity.

[0031] like Figure 3 As shown, each second core-pulling component 90 includes a push plate 91 and a diagonal brace 92. One end of each push plate 91 is detachably fixed to a second side core 50 or a third side core 60, and the other end is slidably connected to plate B 20. Each diagonal brace 92 is inclined and slidably mounted on a push plate 91, with one end extending to the outside of plate B 20, and can slide to plate A during mold closing to push the push plate to slide on plate B 20. In this embodiment, plate B 20 is provided with several third slide rails 3 that are adapted to each push plate 91. Plate A is also provided with several guide plates 93 that are adapted to each diagonal brace 92. Each guide plate 93 is a Z-shaped structure, with one end on plate A and a diagonal hole 4 adapted to a diagonal brace 92. The other end of each guide plate 93 extends to the outside of plate A and is adapted to the third slide rail 3.

[0032] In this embodiment, the second side core 50 and the third side core 60 are used for the snap-fit ​​structure at the other end of the molded product. During mold closing, the inclined brace 92 first contacts plate A and, under its push, pushes the push plate 91 and guide plate 93 to slide towards the moving mold core 10 on plate B 20, while simultaneously pushing the second side core 50 and the third side core 60 into the cavity. In the second stage of mold opening, plate B 20 separates from plate A, the inclined brace 92 exits from plate A and guide plate 93, pushes the push plate 91 and guide plate 93 to slide away from the moving mold core 10 on plate B 20, and simultaneously pulls the second side core 50 and the third side core 60 out of the cavity.

[0033] like Figure 4As shown, one or more first cavities are formed on the fixed mold core, and a second cavity is formed on the moving mold core that is adapted to each of the first cavities. A core structure is provided on the side of each of the two matching first cavities and second cavities.

[0034] This invention features a first core-pulling component 80 on plate A and multiple second core-pulling components 90 on plate B 20. These components, in conjunction with the limiting structure on the mold, allow the first side core 40, the second side core 50, and the third side core 60 to be pulled out and into the cavity sequentially during mold opening and closing. This enables the formation of protective shells and multiple positioning buckle structures on different ends and sidewalls of the product in a single mold closing action. Furthermore, the product can be directly demolded using the fourth core 70. The product requires no subsequent secondary processing, exhibits stable quality, and has low production costs.

[0035] The above does not limit the technical scope of this utility model. Any modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of this utility model shall still fall within the scope of the technical solution of this utility model.
