Description

Technical Field

[0001] The utility model relates to the technical field of molds, in particular to a mold for forming a spray-free high-gloss decorative part. Background Technique

[0002] The mold for forming a spray-free high-gloss decorative part is a special mold for manufacturing plastic products with high gloss and no flow marks. There are some special requirements in the design and manufacturing of this kind of mold to adapt to the processing characteristics of the spray-free high-gloss material and the quality standards of the final product.

[0003] When making common spray-free high-gloss decorative parts, a mold is generally required. The mold generally forms a closed cavity through a moving mold and a fixed mold. The injection molding material of the spray-free high-gloss decorative part is injected into the cavity under the action of high pressure and high temperature, and is made into a spray-free high-gloss decorative part after cooling.

[0004] After the injection molding material is injected into the cavity, gas is also carried and injected into the cavity. Generally, the gas in the cavity is discharged through an exhaust channel. However, since the injection molding material is in a molten state, after entering the cavity, gas is also wrapped inside it. The gas inside the injection molding material is difficult to discharge through the exhaust channel, resulting in the injection molding material still being doped with gas, which reduces the firmness of the formed spray-free high-gloss decorative part. Content of the Utility Model

Specific embodiments

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0026] The present invention provides a technical solution, a mold for forming a spray-free high-gloss decorative part. Please refer to Figure 1 , including a base 1. Please refer to Figure 2 , a drive motor 2 is installed in the inner cavity of the base 1, a drive rod 3 is coaxially installed on the rotor of the drive motor 2, and a drive seat 4 is screwed on the surface of the drive rod 3;

[0027] A mounting seat 5 is arranged on the upper surface of the drive seat 4, and a fixed seat 6 is arranged on the upper surface of the mounting seat 5;

[0028] A fixed mold 7 is arranged on the upper surface of the fixed seat 6, a movable mold 8 is arranged above the fixed mold 7, and an injection port 9 is opened on the upper surface of the movable mold 8. Please refer to Figure 1 , an exhaust passage 10 is opened on the surface of the fixed mold 7;

[0029] Starting the drive motor 2 can drive the drive rod 3 to rotate, thereby driving the drive seat 4 to move, and then driving the mounting seat 5 to move. The mounting seat 5 will drive the fixed seat 6 to move. Since both the fixed mold 7 and the movable mold 8 are installed on the upper surface of the fixed seat 6, the fixed mold 7 and the movable mold 8 can be driven to reciprocate. The injection material in the fixed mold 7 and the movable mold 8 will also shake accordingly. When shaking, the gas inside can be discharged, effectively preventing the injection material from being doped with gas and improving the firmness of the formed spray-free high-gloss decorative part.

[0030] Please refer to Figure 3 , limit ports 11 are opened at the four corners of the upper surface of the movable mold 8, limit rods 12 are installed at the four corners of the upper surface of the fixed mold 7, and the limit rods 12 are inserted into the inner cavities of the limit ports 11. The limit rods 12 and the limit ports 11 enable the movable mold 8 to accurately align with the fixed mold 7.

[0031] On both sides of the fixed mold 7 and the upper parts of both sides of the fixed seat 6, there are first mounting edges 13. A first threaded rod 14 is rotatably connected between the first mounting edges 13. The fixed mold 7 can be fixed on the surface of the fixed seat 6 through the first threaded rod 14. By removing the first threaded rod 14, the fixed mold 7 can be disassembled.

[0032] On the lower parts of both sides of the fixed seat 6, there are second mounting edges 15. Second threaded rods 16 are rotatably connected to the upper surfaces of the second mounting edges 15. The lower parts of the second threaded rods 16 are rotatably connected to the surface of the mounting seat 5. By removing the second threaded rods 16, the fixed seat 6 can be disassembled.

[0033] Please refer to Figure 4 , the driving seat 4 is designed as a cuboid. The driving seat 4 is in close contact with the inner wall of the base 1. When the driving seat 4 is driven by the driving rod 3, it will be limited by the inner wall of the base 1, so that it can move in a straight line.

[0034] Please refer to Figure 3 , on both sides of the bottom of the mounting seat 5, there are sliders 17. Please refer to Figure 4 , on both sides of the upper surface of the base 1, there are chutes 18. The sliders 17 are all embedded in the inner cavity of the chutes 18. The sliders 17 and the chutes 18 enable the mounting seat 5 to move in a straight line.

[0035] First, start the drive motor 2 of the device, which can drive the drive rod 3 to rotate, thereby driving the driving seat 4 to move, and then driving the mounting seat 5 to move. The mounting seat 5 will drive the fixed seat 6 to move. Then, since both the fixed mold 7 and the moving mold 8 are mounted on the upper surface of the fixed seat 6, the fixed mold 7 and the moving mold 8 can be driven to move reciprocally. The injection molding material in the fixed mold 7 and the moving mold 8 will also shake accordingly. When shaking, the gas inside can be discharged, effectively preventing the injection molding material from being doped with gas, improving the firmness of the formed spray-free high-gloss decorative parts. Finally, the fixed mold 7 can be fixed on the surface of the fixed seat 6 through the first threaded rod 14. By removing the first threaded rod 14, the fixed mold 7 can be disassembled. By removing the second threaded rod 16, the fixed seat 6 can be disassembled, which facilitates the replacement of the fixed mold 7.
