Description

Technical Field

[0001] This utility model relates to the field of light guide strip production technology, specifically to an integrated molding mold for light guide strips in new energy vehicles. Background Technology

[0002] An automotive light guide is a functional component that utilizes optical principles to achieve uniform linear light emission. It is typically made of highly transparent PMMA or PC material. When light is injected from LED beads at one end (or side) of the light guide, these microstructures disrupt total internal reflection, precisely guiding and evenly scattering the light across the entire strip surface, thus forming a bright, soft light band without dark areas. The production of light guides requires the use of molding dies.

[0003] For example, authorization announcement number CN223131293U discloses a precision molding mold for automotive taillight light guide strips. This invention includes an upper mold plate, a connecting block assembly below the upper mold plate, an upper mold base below the connecting block assembly, an upper mold core block inside the lower mold base, a lower mold core block inside the upper mold base, an injection port assembly inserted in the middle of the upper mold plate, a support block and a lower mold plate below the lower mold base, a top plate assembly above the lower mold plate, and top posts and top component post assemblies above the top plate assembly. This invention utilizes the cooperation of the top posts and top component post assemblies below the mold to allow the product part to quickly and completely detach from the internal cavity, preventing jamming, avoiding deformation of the light guide strip, and reducing production costs and workload.

[0004] In the above technology, the molding die ejects the injection-molded light guide strip through the ejection mechanism. However, when the ejection mechanism ejects the light guide strip, it is easy to cause deformation of the ejection part of the light guide strip, which affects the production quality of the light guide strip. Therefore, the market urgently needs to develop an integrated molding die for the light guide strip of new energy vehicles to help people solve the existing problems. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Please see Figure 1-4This utility model provides an embodiment of an integrated molding mold for light guide strips in new energy vehicles, comprising a fixed mold base 1 and a movable mold base 2. The movable mold base 2 is connected to one side of the fixed mold base 1. First rectangular fixing members 102 are fixedly connected to both the upper and lower ends of the side end face adjacent to the fixed mold base 1 and the movable mold base 2. Half of the fixed mold 3 is provided at both the upper and lower ends of the middle portion between the two first rectangular fixing members 102. Second rectangular fixing members 201 are fixedly connected to both the upper and lower ends of the side end face adjacent to the fixed mold base 1 of the movable mold base 2. The two second rectangular fixing members 201... Half-moving molds 4 are provided at both the top and bottom ends of the middle section of the space. Symmetrical half-fixed mold grooves 305 are provided on the middle of the side face adjacent to the two half-moving molds 3. Symmetrical half-moving mold grooves 403 are provided on the middle of the side face adjacent to the two half-fixed molds 3. Support rods 105 are fixedly connected to the middle of the side face adjacent to the two first rectangular fixing members 102 and the moving mold base 2 at both the front and rear ends. At the top and bottom of both ends of the middle section 2, there are first guide holes 202. The ends of the four support rods 105 away from the first rectangular fixing member 102 pass through the four first guide holes 202 on the moving mold base 2, extend out of the outside of the moving mold base 2, and are fixedly connected to the fixing plate 106. Hydraulic rods 104 are fixedly connected to the middle of the side face of the two first rectangular fixing members 102 away from the half-fixed mold 3. The telescopic ends of the two hydraulic rods 104 pass through the two first rectangular fixing members 102 and are fixedly connected to the two half-moving molds 4 respectively. Each of the two fixed half molds 3 and the two movable half molds 4 is connected to a linkage rod 5 at both ends of the middle section. Each of the two fixed half molds 3 has a first guide limiting groove 302 at both ends of the middle section. Each of the two movable half molds 4 has a second guide limiting groove 402 at both ends of the middle section. The two linkage rods 5 between the fixed half molds 3 and the movable half molds 4 are inserted into the first guide limiting groove 302 and the second guide limiting groove 402 respectively and are fixedly connected to a circular limiting member 501.

[0020] The entire device is installed on the injection molding machine, so that the fixed mold base 1 is synchronously fixed with the fixed plate 106. The two half-fixed molds 3 are driven to close by two hydraulic rods 104 respectively. When the two half-fixed molds 3 are closed, the two half-moving molds 4 are driven to close by the linkage rod 5 respectively. The hydraulic cylinder on the injection molding machine drives the moving mold base 2 to move towards the fixed mold base 1, so that the two half-moving molds 4 and the two half-fixed molds 3 are closed together. Then, the two half-fixed mold slots 305 and the two half-moving mold slots 403 are closed together to form a complete injection cavity. When the two half-moving molds 4 and the two half-fixed molds 3 are closed, the two ends of the linkage rod 5 are inserted into the first guide limiting groove 302 and the second guide limiting groove 402 respectively for guidance.

[0021] Please see Figure 4 The two first rectangular fasteners 102 are fixedly connected to the front and rear ends of the middle part of the two half-fixed molds 3. The front and rear ends of the middle part of the two half-fixed molds 3 are provided with second guide holes 301. The two first guides 103 pass through the two second guide holes 301 on the two half-fixed molds 3 respectively.

[0022] When the two half-fixed molds 3 move relative to each other to close, they are guided by sliding along the two first guide posts 103 through the two second guide through holes 301 to ensure the accuracy of closing.

[0023] Please see Figure 4 The two second rectangular fasteners 201 are fixedly connected to the front and rear ends of the middle part of the two half-moving molds 4. The front and rear ends of the middle part of the two half-moving molds 4 are provided with third guide holes 401. The two second guides 203 pass through the two third guide holes 401 on the two half-moving molds 4 respectively.

[0024] When the two half-moving molds 4 move relative to each other to close, they are guided by sliding along the two second guide posts 203 through the two third guide through holes 401 to ensure the accuracy of closing.

[0025] Please see Figure 2 and Figure 3 A semi-circular clamping groove 303 is provided in the middle of the side end face of each of the two half-fixed molds 3. One side of each of the two semi-circular clamping grooves 303 is connected to the two half-fixed mold grooves 305. An injection tube 101 is fixedly connected in the middle of the fixed mold base 1. One end of the injection tube 101 extends to the middle between the two half-fixed molds 3. A cutting knife mechanism 304 is provided in the upper half-fixed mold 3 on the side adjacent to the half-fixed mold groove 305.

[0026] When the two half-fixed molds 3 close, the two semi-circular clamping grooves 303 simultaneously clamp the injection tube 101, connecting the injection tube 101 with the interior of the two half-fixed mold grooves 305. Injection is then performed through the injection tube 101 into the two half-fixed mold grooves 305 and the two half-moving mold grooves 403, forming a complete injection cavity. After injection molding and cooling, the cutting blade mechanism 304 cuts the injection material between the injection tube 101 and the two half-fixed mold grooves 305. Then, the moving mold base 2 moves to separate from the fixed mold base 1, thus allowing the two half-fixed molds to... The moving mold 4 separates from the two half-fixed molds 3. At this time, the injected light guide strip stays inside the two half-fixed mold slots 305 or the two half-moving mold slots 403. The two hydraulic rods 104 drive the separation between the two half-fixed molds 3 and the two half-moving molds 4, so that the two half-fixed mold slots 305 and the two half-moving mold slots 403 are separated, exposing the large surface of the injected light guide strip. Personnel can directly pick up the light guide strip, or the light guide strip can fall directly between the half-moving mold 4 and the half-fixed mold 3 and detach.

[0027] Working Principle: In use, the entire device is first installed on the injection molding machine. During mold closing, the hydraulic cylinder on the injection molding machine pushes the moving mold base 2 towards the fixed mold base 1. Simultaneously, two hydraulic rods 104 move synchronously, pushing the two half-fixed molds 3 to move towards each other and close along the first guide post 103. Through the linkage rod 5, the two half-moving molds 4 are driven to move towards each other and close along the second guide post 203. Finally, the two half-fixed molds 3 and the two half-moving molds 4 are completely closed. The two half-fixed mold grooves 305 and the two half-moving mold grooves 403 together form a complete light guide strip forming cavity. The end of the injection tube 101 is tightly covered by two semi-circular clamping grooves 303, communicating with the cavity. The injection molding machine injects molten plastic into the cavity through the injection tube 101. After pressure holding and cooling, the upper cutting blade mechanism 304 actuates to cut off the gate. Subsequently, the moving mold base 2 retracts under the action of the injection molding machine's hydraulic cylinder, separating the moving mold part from the fixed mold part. The formed light guide strip is usually retained in the moving mold or fixed mold cavity. Next, the two hydraulic rods 104 retract, pulling the two halves of the fixed mold 3 apart, and simultaneously separating the two halves of the moving mold 4 through the linkage rod 5. The cavity is fully opened, and the formed light guide strip naturally loosens due to the lack of ejection force. The operator can easily remove it or let it fall off automatically, thus completing one production cycle.

[0028] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
