Description

Technical Field

[0001] This utility model relates to the field of injection mold technology, and in particular to a two-color injection mold for a vehicle-mounted camera bracket. Background Technology

[0002] Vehicle-mounted cameras are devices used to provide scientific evidence for handling traffic accidents. They have functions such as improving driving safety and driver assistance. Specifically, they can reduce blind spots: Vehicle-mounted cameras can be installed in key locations such as the front, rear, left, and right of a vehicle to help drivers better observe blind spots around the vehicle and avoid collisions caused by blind spots; real-time traffic monitoring: Through vehicle-mounted cameras, drivers can understand the road conditions ahead in real time, including traffic congestion, accident scenes, and other information, thereby making more reasonable driving decisions; pedestrian detection and avoidance: Some advanced vehicle-mounted camera systems also have pedestrian detection functions, which can promptly remind the driver when pedestrians are detected, and even automatically take avoidance measures to improve driving safety; lane keeping: Vehicle-mounted cameras can monitor the distance and angle between the vehicle and the lane lines in real time, and promptly remind the driver or automatically correct the vehicle when it deviates from the lane to maintain stable driving.

[0003] Vehicle cameras require brackets to mount them inside and outside the vehicle. These brackets are typically made of plastic and therefore require injection molding. The bracket includes a first panel, a second panel, and several connecting feet located on one side of the first panel. Each connecting foot is positioned circumferentially around the panel. The first panel has a flat portion and a raised portion, with an arc-shaped transition between the raised and flat portions, and a first through-slot at the junction. The second panel is located on the flat portion of the first panel and has a corresponding second through-slot. Grooves are formed on the outer sides of the connecting feet. However, existing injection molding methods cannot mold the first and second panels as a single unit; they are molded separately and then fixed together. Furthermore, the through-slots and grooves are not formed during injection molding and require subsequent processing, resulting in slow processing efficiency and poor quality. Summary of the Invention

[0004] The purpose of this utility model is to overcome the defects of the prior art. This utility model provides a two-color injection mold for a vehicle camera bracket. The two panels are injection molded into one piece by the two-color mold. In addition, the groove and through groove can be formed at the same time during injection molding. The processing efficiency is high and the product molding effect is good.

[0005] The technical solution of this utility model: A two-color injection mold for a vehicle-mounted camera bracket, comprising a first mold and a second mold. The first mold includes a first front mold, a first front mold core, a first rear mold, a first rear mold core, and a first ejector assembly. The first front mold has a first injection port, and the first front mold core has a first molding area for molding a first panel. The first injection port communicates with the first molding area. The first rear mold core has a protrusion corresponding to the position of the first molding area and several second molding areas for molding connecting feet. The second molding areas are arranged circumferentially along the protrusion. The first mold also includes... A first front mold slide and a first rear mold slide, the first front mold slide including a first front mold slide rod and a first front mold slide block, the first front mold slide block being connected to the first front mold, the first front mold slide block having a connecting groove and inclined surfaces on both sides of the connecting groove, one end of the first front mold slide rod extending into the connecting groove, and the other end extending into the first molding area, during mold opening, the first front mold slide block and the first front mold slide slide synchronously, driving the first front mold slide rod to slide outwards from the first molding area, during mold closing, the inclined surfaces on the first front mold slide block pressing against the first front mold slide rod, driving the first front mold slide rod to slide outwards from the first molding area. The first mold slides within the first forming area. The first front mold slide rod is configured to correspond to the through slot on the first panel for through slot formation. The first rear mold slide includes a first rear mold slide block, a sliding block, and a first rear mold slide rod. The first rear mold slide block is connected to the first front mold. The sliding block has an inclined groove. The first rear mold slide block has an inclined drive block that slides within the groove. One end of the first rear mold slide rod is connected to the sliding block, and the other end extends into the second forming area. When the mold opens, the first rear mold slide block slides synchronously with the first front mold. The drive block slides within the groove to drive the sliding block further away. When the mold is closed, the drive block pushes the sliding block towards the molding area to allow the first rear mold slide rod to extend into the second molding area for the molding of the slot. The second mold includes a second front mold, a second front mold core, a second rear mold, a second rear mold core, and a second ejection assembly. The second front mold is provided with a second injection port, and the second front mold core is provided with a third molding area for molding the second panel. The second injection port communicates with the third molding area. The rear mold of the second mold is the same as the first mold. The second mold also includes a second front mold slide, which has the same structure as the first front mold slide.

[0006] Using the above technical solution, the first mold is used to injection mold the first panel and the connecting feet. After the mold is opened, the rear molds of the first mold and the second mold are interchanged. The second mold is used to injection mold the second panel on the first panel, so that the two panels can be injection molded into one piece, and the structure between them is more solid. In addition, because of the setting of the front mold slide and the rear mold slide, through grooves and slots can be formed during injection molding, without the need for subsequent processing, which is more efficient.

[0007] A further feature of this invention is as follows: The first front mold sliding rod includes a first rod body and a second rod body that are separately configured. Both the first rod body and the second rod body are square in shape. The second rod body is sleeved on the outer periphery of the first rod body and is fixedly connected by a connecting rod. The length of the second rod body is less than the length of the first rod body. The end of the first rod body is provided with a connecting block that is configured in a "T" shape. The first front mold sliding block is provided with an inclined connecting groove. The connecting block is located in the connecting groove. The end of the second rod body abuts against the inclined surface.

[0008] The above-mentioned further configuration facilitates the connection between the first front mold sliding rod and the first front mold sliding block, so that when the first front mold sliding block slides synchronously with the first front mold, it can better drive the first front mold sliding rod to move. The first rod body slides synchronously with the second rod body, resulting in a robust structure and good stability.

[0009] A further feature of this invention is that the first rear mold slide has four sets arranged along the circumference of the first rear mold core. The first rear mold core has a guide groove corresponding to the position of the first rear mold slide rod. One end of the first rear mold slide rod is connected to the sliding block, and the other end has at least two spaced positioning strips, which are located in the second forming area when the mold is closed.

[0010] The driving block includes a connecting part and a pressing part arranged in a "T" shape. The connecting part is connected to the first rear mold sliding block. The pressing part is slidably disposed in the slide groove. The sliding block has installation channels on both sides of the slide groove. The installation channels are provided with pressing rods and pressing springs. One end of the pressing spring abuts against the bottom wall of the installation channel, and the other end abuts against the pressing rod. The end of the pressing rod extends out of the installation channel into the slide groove. The end of the pressing rod has a plane that abuts against both sides of the pressing part. When the mold is opened, the driving block slides in the slide groove. The two sides of the pressing part act on the plane of the pressing rod to drive the first rear mold sliding rod to slide away from the second molding area.

[0011] With the above-mentioned further configuration, the structure is simple, easy to operate, and has good stability. When the mold is opened, the driving block and the first rear mold slide block slide synchronously with the first front mold. The pressing part slides in the inclined groove and pushes against the pressing rod, so that the pressing rod drives the sliding block to slide, thereby allowing the end of the first rear mold slide rod to slide out of the second product forming area for subsequent ejection. The pressing rod has a flat surface that abuts against the pressing part, so that the contact surface between the two is large and the pressing rod is better driven to move. When the mold is closed, when the pressing part slides in the inclined groove, it pushes the first rear mold slide rod, causing it to slide into the second forming area.

[0012] A further feature of this invention is that the first ejector assembly and the second ejector assembly have the same structure, both including an ejector plate and a plurality of first ejector pins and second ejector pins disposed on the ejector plate. A through hole is provided on the protrusion corresponding to the position of each first ejector pin, the end of the first ejector pin is located in the through hole, and the second ejector pin corresponds to the position of the second forming area.

[0013] With the above-mentioned further configuration, after the mold is opened, the first ejector pin and the second ejector pin work simultaneously. The first ejector pin pushes the first panel, and the second ejector pin pushes the connecting foot to realize the ejection of the product. The first ejector pin is circular and the second ejector pin is flat, which better fits the product and better drives the molded product to be ejected. Attached Figure Description

[0030] like Figure 1-11As shown, a two-color injection mold for a vehicle-mounted camera bracket includes a first mold 1 and a second mold 2. The first mold 1 includes a first front mold 11, a first front mold core 11, a first rear mold 13, a first rear mold core 14, and a first ejector assembly 15. The first front mold 11 has a first injection port 111, and the first front mold core 11 has a first molding area 121 for molding a first panel. The first injection port 111 communicates with the first molding area 121. The first rear mold core 14 has a protrusion 141 corresponding to the position of the first molding area 121 and several second molding areas 142 for molding connecting feet. The second molding areas 142 are arranged circumferentially along the protrusion. The first mold 1 also includes a first front mold slide 16 and a first rear mold slide 17. The first front mold slide 16 includes a first front mold slide rod 161 and a first front mold slide block 162. The first front mold slide block 162 is connected to the first front mold 11. The first front mold slide block 162 is provided with a connecting groove 1621 and inclined surfaces 1622 located on both sides of the connecting groove 1621. One end of the first front mold slide rod 161 extends into the connecting groove 1621, and the other end extends into the first molding area 121. When the mold is opened, the first front mold slide block 162 slides synchronously with the first front mold 11, and drives the first front mold slide rod 161 to slide outward of the first molding area 121. When the mold is closed, the inclined surfaces 1622 on the first front mold slide block 162 press against the first front mold slide rod 161, driving the first front mold slide rod 161 towards the first molding area 121. The first front mold slide rod 161 is configured to correspond to the through groove on the first panel for through groove forming. The first rear mold slide 17 includes a first rear mold slide block 171, a sliding block 172, and a first rear mold slide rod 173. The first rear mold slide block 171 is connected to the first front mold 11. The sliding block 172 has an inclined slide groove 1721. The first rear mold slide block 171 has an inclined drive block 1711, which slides within the slide groove 1721. One end of the first rear mold slide rod 173 is connected to the sliding block 172, and the other end extends into the second forming area 132. When the mold is opened, the first rear mold slide block 171 slides synchronously with the first front mold 11, and the drive block 1711 slides within the slide groove 1721 to drive the mold. The sliding block 172 slides away from the second molding area 132. When the mold is closed, the driving block 1711 pushes the sliding block 172 towards the molding area so that the first rear mold slide rod 173 extends into the second molding area 132 to form the groove. The second mold 2 includes a second front mold 21, a second front mold core, a second rear mold 22, a second rear mold core, and a second ejection assembly 23. The second front mold 21 is provided with a second injection port 211, and the second front mold core is provided with a third molding area for forming the second panel. The second injection port 211 communicates with the third molding area. The rear mold of the second mold 2 is the same as that of the first mold 1. The second mold 2 also includes a second front mold slide, which has the same structure as the first front mold slide 16.The first mold 1 injection molds the first panel and connecting feet. After mold opening, the rear molds of the first mold 1 and the second mold 2 are interchanged. The second mold 2 then injection molds the second panel onto the first panel, allowing the two panels to be injection molded into one piece, resulting in a more robust structure. Furthermore, the use of front and rear mold slides allows for the formation of through grooves and slots during injection molding, eliminating the need for subsequent processing and increasing efficiency.

[0031] The first front mold sliding rod 161 includes a split first rod body 1611 and a second rod body 1612. Both the first rod body 1611 and the second rod body 1612 are square in shape. The second rod body 1612 is sleeved on the outer periphery of the first rod body 1611 and is fixedly connected by a connecting rod 3. The length of the second rod body 1612 is less than the length of the first rod body 1611. The end of the first rod body 1611 is provided with a T-shaped connecting block 1613. The 162 is provided with an inclined connecting groove 1621, and the connecting block 1613 is located in the connecting groove 1621. The end of the second rod 1612 abuts against the inclined surface 1622, which facilitates the connection between the first front mold sliding rod 161 and the first front mold sliding block 162. This allows the first front mold sliding block 162 to better drive the first front mold sliding rod 161 to move when it slides synchronously with the first front mold. The first rod 1611 and the second rod 1612 slide synchronously, resulting in a solid structure and good stability.

[0032] The first rear mold slide 17 has four sets arranged around the first rear mold core 14. The first rear mold core 14 has guide grooves corresponding to the positions of the first rear mold slide rods 173. One end of the first rear mold slide rod 173 is connected to the sliding block 172, and the other end has at least two spaced positioning strips, which are located within the second molding area 132 during mold closing. The driving block 1711 includes a connecting part 1712 and a T-shaped pressing part 1713. The connecting part 1712 is connected to the first rear mold slide block 171, and the pressing part 1713 is slidably disposed within the slide groove 1721. The sliding block 1712... 2. An installation channel is provided on both sides of the slide groove 1721. A pressing rod 1722 and a pressing spring 1723 are provided in the installation channel. One end of the pressing spring 1723 abuts against the bottom wall of the installation channel, and the other end abuts against the pressing rod 1722. The end of the pressing rod 1722 extends out of the installation channel into the slide groove 1721. The end of the pressing rod 1722 has a plane 1724 that abuts against both sides of the pressing part 1713. When the mold is opened, the driving block 1711 slides in the slide groove 1721, and the two sides of the pressing part 1713 act on the plane 1724 of the pressing rod 1722 to drive the first rear mold. The sliding rod 173 slides away from the second forming area 132. It has a simple structure, is easy to operate, and has good stability. During mold opening, the drive block 1711, the first rear mold sliding block 171, and the first front mold 11 slide synchronously. The pressing part 1713 slides within the inclined groove 1721 and pushes against the pressing rod 1722, causing the pressing rod 1722 to drive the sliding block 172 to slide. This allows the end of the first rear mold sliding rod 173 to slide out of the second product forming area for subsequent ejection. The pressing rod 1722 has a flat surface 1724 that abuts against the pressing part 1713, resulting in a large contact area between the two. When the good drive pressure rod 1722 moves, when the mold is closed, the pressure part 1713 slides in the inclined slide groove 1721, which will push the first rear mold slide rod 173, causing it to slide into the second molding area 132 and press against the pressure rod 1722, so that the two pressure rods 1722 move in opposite directions. The pressure rod 1722 slides into the side of the two sides of the pressure part 1713 near the connecting part 1712. The pressure spring 1723 drives the two pressure rods 1722 to move towards each other and abut against the pressure part 1713. The pressure rod 1722 is set to abut against the pressure part 1713 under the pushing force of the pressure spring 1723.

[0033] The first ejection assembly 15 and the second ejection assembly 23 have the same structure, both including an ejection plate 151 and a plurality of first ejector pins 152 and second ejector pins 153 disposed on the ejection plate 151. Through holes are opened on the protrusion 131 corresponding to the positions of each first ejector pin 152. The ends of the first ejector pins 152 are located in the through holes, and the second ejector pins 153 are located at the positions of the second molding area 132. After the mold is opened, the first ejector pins 152 and the second ejector pins 153 work simultaneously. The first ejector pins 152 push the first panel, and the second ejector pins 153 push the connecting feet to realize the ejection of the product. The first ejector pins 152 are circular and the second ejector pins 153 are flat, which better fits the product and better drives the molded product to be ejected. The specific working principle of the ejector pin assembly belongs to the prior art, so it will not be described in detail.
