[0001] The utility model relates to the technical field of automobile headlamp production, in particular to an injection mold for automobile headlamps which is convenient to clean. Background Art

[0002] Automobile headlamps are tools for vehicle night driving illumination on roads and also tools for emitting various vehicle driving signal prompts. Headlamps are generally divided into headlamps, tail lamps, turn signals, etc.

[0003] The outer shell of automobile headlamps is generally produced by injection molding, so corresponding injection molds will be used. After demolding, oil, raw material residues, etc. often remain in the mold cavity. Therefore, the injection mold needs to be cleaned after use. However, due to the relatively large volume of automobile headlamps, the corresponding injection mold is also large, and the injection mold mostly uses metal materials to ensure a long service life. This, however, also results in the injection mold being too large and heavy. During the cleaning process of the mold cavity, operations such as handling and moving are inevitably encountered, which also increases the cleaning difficulty of the injection mold. Summary of the Utility Model

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0027] Referring to Figures 1-4 , an injection mold for automobile headlights that is convenient for cleaning, includes a lower mold and an upper mold disposed opposite to the lower mold;

[0028] The upper mold includes a first mold plate 4. A first mold block 5 is installed at the center of the bottom of the first mold plate 4, and a mold cavity 6 corresponding to the first mold block 5 is provided at the top of the first mold plate 4 for the injection raw material to accumulate in the mold cavity 6;

[0029] First through holes 7 are provided at the edges of the first mold plate 4. A first mold base 1 is provided below the first mold plate 4. A first cavity 2 is provided at the top of the first mold base 1, and the first cavity 2 corresponds to the first mold block 5, so that the first mold plate 4 has a concave surface for injection molding of automobile headlights and presents a thin plate shape; First screw holes 3 are provided at the top corners of the first mold base 1, and a first screw 8 corresponding to the first screw hole 3 is provided above the first through hole 7. A limit hole 9 is coaxially provided at the top of the first screw 8, so that the first mold plate 4 can be fixed on the top of the first mold base 1 through the first screw 8. During injection molding, the first mold plate 4 can be closely seated on the first mold base 1, and the first mold base 1 can provide support for the first mold plate 4;

[0030] Such as Figure 3 And Figure 4As shown in the figure, the lower mold includes a second mold plate 16. A second mold block 17 is installed at the center of the bottom of the second mold plate 16. The second mold block 17 corresponds to the cavity 6, enabling the second mold plate 16 to function as a forming punch. Second through holes 19 are provided at the corners of the second mold plate 16. A second mold base 12 is arranged above the second mold plate 16. Second screw holes 15 are provided at the bottom corners of the second mold base 12. A second screw rod 21 is arranged below the second through hole 19. A limiting rod 22 corresponding to the limiting hole 9 is installed at the bottom of the second screw rod 21. The second mold plate 16 is fixed to the second mold base 12 through the threaded connection of the second screw rod 21 in the second screw hole 15, ensuring sufficient pressure when the second mold plate 16 is pressed down.

[0031] Specifically, the mold plates are fixed to the mold bases through screw rods. That is, after injection molding is completed, the screw rods can be rotated to remove the mold plates from the mold bases. Thus, the plate-shaped forming molds are more convenient to carry and move compared to block-shaped ones, facilitating the cleaning operation of the injection mold.

[0032] Among them, in order to further reduce the weight of the second mold plate 16, a second cavity 18 corresponding to the second mold block 17 is provided at the top of the second mold plate 16, making the second mold plate 16 form a plate-shaped structure with a forming punch. A support block 14 corresponding to the second cavity 18 is installed at the bottom of the second mold base 12. After the second mold plate 16 is installed on the second mold base 12, the support block 14 fills the second cavity 18, ensuring the fullness of the second mold block 17. When the second mold plate 16 is pressed down, the second mold block 17 will not deform under pressure due to its hollow structure, affecting injection molding.

[0033] Furthermore, a first screw head 10 is installed at the edge of the first screw rod 8 away from the first mold base 1, and a second screw head 23 is installed at the edge of the second screw rod 21 away from the second mold base 12. That is, corresponding screw heads are provided at the ends of the screw rods to facilitate the rotation of the screw rods in the screw holes.

[0034] It should be noted that due to the setting of the screw heads, there will be gaps between the upper and lower molds when they are combined. Therefore, a first cushion plate 11 is installed along the top edge of the first cavity 2, and the thickness of the first cushion plate 11 corresponds to the thickness of the first screw head 10. A second cushion plate 20 is installed along the top edge of the second mold block 17, and the thickness of the second cushion plate 20 corresponds to the thickness of the second screw head 23, ensuring the sealing performance around the forming cavity after the second mold block 17 is placed in the cavity 6, so as to achieve rapid forming after the injection molding raw material is injected.

[0035] In use, connection seats 13 are installed on the relatively far - away sides of the first mold base 1 and the second mold base 12, and the mold bases can be correspondingly installed on the injection - molding device. Then, a screw is taken to install the corresponding mold plate on the mold base. An injection - molding pipe 24 is installed at the bottom of the first cavity 2, and a channel communicating with the second injection - molding pipe 24 is provided on the side surface of the first mold base 1. A jack 25 corresponding to the injection - molding pipe 24 is provided at the bottom of the cavity 6. When the upper and lower molds are combined, the injection - molding raw material is injected into the channel, and then the injection - molding raw material will flow into the cavity 6. With the cooling after injection, the shell of the required automotive headlight can be formed. Then, when it is necessary to clean the cavity 6, the screw can be directly unscrewed, and the mold plate can be removed from the mold base, and then it can be taken to one side for cleaning work.

[0036] The above - mentioned is only the preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, makes equivalent replacements or changes, and all should be covered within the protection scope of the present utility model.
