Description

Technical Field

[0001] This utility model relates to the technical field of automotive trim production equipment, specifically to a multi-cavity injection mold for automotive trim production. Background Technology

[0002] With social progress and development, the level of science and technology is constantly improving, and the use of automobiles is becoming more and more frequent. The requirements for automobile production and processing are also constantly being refined. Injection molds used in processing play a significant role, providing great convenience for people in processing, saving a lot of time, and making operations increasingly convenient.

[0003] Existing injection molds for automotive trim production lack multi-cavity structures, such as the one disclosed in application number CN202022734051.0. These existing injection molds for automotive production do not have the capability for simultaneous multi-cavity injection operation. Single-cavity injection molds can only produce one product at a time, significantly reducing production efficiency compared to multi-cavity molds. Due to the limited output per cycle, more injection cycles are required to achieve the same total output, thus extending the overall production time. In single-cavity mold production mode, the utilization rate of the injection molding machine is relatively low because after each injection cycle, it is necessary to wait for the mold to open, the product to be removed, and the mold to close again, during which time the injection molding machine is idle. The lack of simultaneous multi-cavity injection operation capability in existing automotive injection molds leads to drawbacks such as low production efficiency, increased costs, poor product quality consistency, and insufficient flexibility.

[0004] Therefore, it is necessary to invent a multi-cavity injection mold for the production of automotive trim parts to solve the above problems. Utility Model Content

Detailed Implementation

[0023] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0024] This utility model provides, for example Figure 1-5 The multi-cavity injection mold for automotive trim production shown includes a base 1, columns 2, a top seat 3, an upper top plate 4, and a lower mold frame 5. Columns 2 are located on both outer sides of the base 1. The top seat 3 is located on the top of each column 2. An injection tube 301 is installed through the center of the top seat 3. A retaining ring 302 is installed at the point where the injection tube 301 penetrates the top surface of the top seat 3. Four injection tubes 301 are provided, and four retaining rings 302 are correspondingly installed. The bottom end of the injection tube 301 is connected to the interior of the upper top plate 4. The upper top plate 4 is located directly below the center of the top seat 3, and a compression mold base 40 is located below the upper top plate 4. 1. Four mold bases 401 are provided. Each mold base 401 has a docking post 402 on both sides of its outer surface. A matching docking groove 403 is provided directly below the docking post 402. The docking grooves 403 are respectively opened in the middle of the two sides of the surface of the base 1. A lower mold frame 5 is provided directly below the upper top plate 4. The lower mold frame 5 is located in the middle of the surface of the base 1. There are four lower mold frames 5. An injection cavity 501 is opened in the middle of the surface of the lower mold frame 5. A slot 502 is opened on one side of the outer wall of two lower mold frames 5. A wedge block 503 that engages with the slot 502 is opened on the corresponding surface of the other two lower mold frames 5.

[0025] A fixed seat 6 is fixedly installed at each of the four corners of the base 1. The fixed seat 6 is located below the lower mold frame 5. A moving groove 601 is opened in the middle of the surface of the fixed seat 6. A reciprocating screw 602 is installed in the middle of the moving groove 601. A first motor 603 is installed at the end of the reciprocating screw 602. A moving seat 604 is installed on the surface of the reciprocating screw 602. The moving seat 604 is located in the middle of the moving groove 601 and is fixedly connected to the bottom of the lower mold frame 5. An installation ring 7 is installed on the surface of the column 2. The installation ring 7 is located between the base 1 and the top seat 3. One side of the outer wall of the two installation rings 7 is fixedly connected to the two sides of the outer wall of the upper top plate 4. A pressure rod 701 is set above the top side of the installation ring 7. The upper end of the pressure rod 701 is connected to a second motor 702. The second motor 702 is located on both sides of the surface of the top seat 3.

[0026] The working principle of this practical application is as follows:

[0027] Refer to the instruction manual appendix Figure 1-5 For this type of multi-cavity injection mold used in the production of automotive trim parts, during use, the injection tube 301 is first installed through the middle of the top seat 3 to inject molten plastic material into the mold. The bottom end of the injection tube 301 is connected to the inside of the upper top plate 4. When the upper top plate 4 descends and contacts the mold base 401, the injection tube 301 starts working, injecting plastic into the cavity formed by the lower mold frame 5 and the upper top plate 4. Since the mold is designed as a multi-cavity mold, multiple automotive trim parts can be produced simultaneously. Through the cooperation of the pressure rod 701 on the mounting ring 7 and the second motor 702, the upper top plate 4 can be raised and lowered, thereby controlling the closing and opening of the mold. When the mold is closed, the mold base 401 and the upper top plate 4 are connected. The lower mold frames 5 are in close contact to form a complete cavity. When the mold is opened, the pressure mold base 401 rises to facilitate the removal of the finished product. The moving groove 601 on the surface of the fixed base 6, the reciprocating screw 602 and the first motor 603 work together to realize the left and right movement of the lower mold frames 5. This helps to adjust the mold position during the injection molding process and ensure that the plastic can be evenly filled into each cavity. At the same time, this design also facilitates the replacement and maintenance of the mold. The lower mold frames 5 are connected by the engaging structure of the slot 502 and the wedge block 503. This design not only enhances the overall stability of the mold, but also helps to maintain the synchronous movement of each part when the mold is opened, thereby avoiding defects in the finished product.

[0028] When using this device, first check that all parts of the mold are intact and ensure that key components such as the injection tube 301 and the motor are working properly. Then, prepare the molten plastic material and connect it to the injection tube 301. Start the second motor 702, and use the pressure rod 701 to lower the upper plate 4 to a position where it contacts the lower mold frame 5, forming a complete cavity. Start the injection tube 301 to inject the molten plastic material into the cavity. During the injection process, the injection speed and pressure parameters can be adjusted as needed to ensure that the plastic is evenly filled into each cavity. After the injection is completed, start the second motor 702 again, and use the pressure rod 701 to raise the upper plate 4 to a certain height, opening the mold. Then, remove the finished product from the lower mold frame 5 and perform necessary inspection and cleaning. If it is necessary to change the mold or adjust the mold position, the first motor 603 can be started, and the lower mold frame 5 can be moved left and right through the reciprocating screw 602 and the moving seat 604. Repeat the above steps to continuously produce multiple automotive trim parts.
