Description

Technical Field

[0001] This utility model belongs to the field of injection mold technology, specifically a soft rubber dual-color high brake lamp housing injection mold. Background Technology

[0002] Injection molds are tools used to produce plastic products, giving them a complete structure and precise dimensions. As a crucial tool in the manufacturing industry, injection molds not only affect product quality but also production efficiency and cost control. Specifically, the design and manufacture of injection molds require a high degree of specialization and precision to ensure that the final product accurately meets design specifications. Injection molding technology is widely used in modern manufacturing due to its advantages such as fast molding speed, high production efficiency, and the ability to create complex shapes.

[0003] For example, a dual-color lampshade rapid injection mold with publication number CN219055173U includes a mold housing and a molding mold base B. The molding mold base B is located on the inner wall of the right end of the mold housing, and the molding mold base A is located on the left side of the molding mold base B. Opening and closing guide pillars are internally connected at the four corners of the molding mold base A and the molding mold base B. By adding a new type of mold opening warning device to the outside of the mold opening and closing cylinder of the dual-color lampshade rapid injection mold, the mold opening warning device can provide a warning for the mold opening stroke of the molding mold base A without affecting the normal mold opening of the molding mold base A. When the cylinder shaft excessively drives the molding mold base A to move to the left to open the mold, the mold opening warning device will produce a sharp whistle to remind the operator that the mold opening stroke of the molding mold base A is too large. This can help the operator adjust the mold opening and closing cylinder in time to ensure that the mold opening and closing cylinder can drive the molding mold base A to open and close the mold within the optimal stroke.

[0004] This injection mold only has a single moving mold and a single fixed mold. In the process of two-color injection molding, after one molding, it is necessary to change the injection material of a different color and then perform a second molding. This structure requires precise calculation of the material capacity of one molding, which results in material waste. At the same time, changing the material consumes a lot of time. In order to solve the above problems, a soft rubber two-color high brake lamp housing injection mold is proposed. Utility Model Content

[0005] The purpose of this utility model is to solve the above problems by providing a soft rubber dual-color high-speed brake lamp housing injection mold, comprising:

[0006] A fixed base plate has slide rails fixedly installed on both the left and right sides of its upper surface. A movable seat is slidably connected to the upper surface of each of the two slide rails. A mold clamping base and an injection molding machine are fixedly installed on the upper surface of the movable seat. The output end of the injection molding machine is connected to the input end of the mold clamping base. A moving mold is fixedly installed on the outer wall of the mold clamping base on the side away from the injection molding machine.

[0007] A fixed base is fixedly installed on the middle of the upper surface of a fixed base plate. The fixed base is located between the two mold clamping bases. A rotating plate is rotatably connected inside the fixed base. A fixed mold is fixedly installed on one outer wall of the rotating plate.

[0008] Through the above technical solution, during the injection molding process, the movable seat located on the left side of the fixed base plate moves to the right along the slide rail, thereby combining the moving mold and the fixed mold to form a primary molding mold. The injection molding machine injects raw material into the primary molding mold to form a single-color hard rubber part. After the primary molding is completed, the rotating plate rotates. At this time, the movable seat located on the right side of the fixed base plate moves to the left along the slide rail, thereby combining the moving mold and the fixed mold to form a secondary molding mold. The injection molding machine injects the second-color material into the cavity to form a two-color soft and hard rubber product, thereby improving the injection molding efficiency of the injection mold.

[0009] In a preferred embodiment, cylinders are fixedly installed on both the left and right sides of the upper surface of the fixed base plate, and the output shaft end of the cylinder is fixedly connected to the outer wall of one side of the movable seat.

[0010] The above technical solution uses a cylinder to drive the moving seat to move along the slide rail.

[0011] In a preferred embodiment, a motor is fixedly installed on one side of the outer wall of the fixed base, and the output shaft of the motor is fixedly connected to one side of the rotating plate.

[0012] The above technical solution uses a motor to drive the rotating plate to rotate.

[0013] In a preferred embodiment, positioning rib grooves are provided at all four corners of the outer wall on one side of the moving mold, and positioning ribs that are adapted to the positioning rib grooves are fixedly installed at all four corners of the outer wall on one side of the fixed mold.

[0014] Through the above technical solution, when the moving mold and the fixed mold are closed, the positioning rib groove and the positioning rib make the moving mold and the fixed mold fit tightly together.

[0015] In a preferred embodiment, a slide block is fixedly installed on one side of the outer wall of the fixed mold, and two combined molds are slidably connected to the outer wall of the slide block. The outer wall of the combined mold is provided with multiple inclined grooves, and multiple inclined rods adapted to the inclined grooves are fixedly installed on one side of the outer wall of the moving mold.

[0016] With the above technical solution, when the moving mold and the fixed mold are closed, the inclined rod is inserted into the inclined groove. During this process, the two combined molds move inward and towards each other along the slide block to form a molding cavity. On the one hand, this increases the clamping force between the moving mold and the fixed mold, preventing the workpiece from producing burrs after molding. On the other hand, during the demolding process, the two combined molds move outward, thereby releasing the molding cavity and facilitating tool demolding.

[0017] In a preferred embodiment, each of the fixed bases has a through guide rod fixedly installed on its outer wall, and the two mold clamping bases are slidably connected to the left and right sides of the guide rods respectively.

[0018] In summary, due to the adoption of the above technical solutions, the beneficial effects of this utility model are: this utility model proposes a soft rubber dual-color high brake lamp housing injection mold.

[0019] 1. During the injection molding process, the movable seat located on the left side of the fixed base plate moves to the right along the slide rail, thereby combining the moving mold and the fixed mold to form a primary molding mold. The injection molding machine injects raw material into the primary molding mold to form a single-color hard rubber part. After the primary molding is completed, the rotating plate rotates. At this time, the movable seat located on the right side of the fixed base plate moves to the left along the slide rail, thereby combining the moving mold and the fixed mold to form a secondary molding mold. The injection molding machine injects the second color material into the cavity to form a two-color soft and hard rubber product, thereby improving the injection efficiency of the injection mold.

[0020] 2. When the moving mold and the fixed mold are closed, the inclined rod is inserted into the inclined groove. During this process, the two combined molds move inward and towards each other along the slide block to form a molding cavity. On the one hand, this increases the clamping force between the moving mold and the fixed mold to prevent the workpiece from producing burrs after molding. On the other hand, during the demolding process, the two combined molds move outward to release the molding cavity and facilitate tool demolding. Attached Figure Description

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] The following will combine Figure 1-3 A detailed description is provided of a soft rubber dual-color high-speed brake lamp housing injection mold according to an embodiment of this utility model.

[0027] Example:

[0028] A soft rubber dual-color high-speed brake lamp housing injection mold, comprising:

[0029] A fixed base plate 1 has slide rails 2 fixedly installed on both the left and right sides of its upper surface. Movable seats 4 are slidably connected to the upper surfaces of the two slide rails 2. Cylinders 3 are fixedly installed on both the left and right sides of the upper surface of the fixed base plate 1. The output shaft end of the cylinder 3 is fixedly connected to the outer wall of one side of the movable seat 4. The cylinder 3 drives the movable seat 4 to move along the slide rails 2. A mold clamping base 5 and an injection molding machine 18 are fixedly installed on the upper surface of the movable seat 4. The output end of the injection molding machine 18 is connected to the input end of the mold clamping base 5. A moving mold 6 is fixedly installed on the outer wall of the mold clamping base 5 away from the injection molding machine 18. During the injection process, the movable seat 4 located on the left side of the fixed base plate 1 moves to the right along the slide rails 2, thereby combining the moving mold 6 and the fixed mold 9 to form a one-time molding mold. The injection molding machine 18 injects raw materials into the one-time molding mold to form a single-color hard rubber part.

[0030] The fixed base 7 is fixedly installed in the middle of the upper surface of the fixed base plate 1. The outer wall of the fixed base 7 is fixedly installed with guide rods 11 that pass through it. The two mold clamping bases 5 are slidably connected to the left and right sides of the guide rods 11 respectively. The fixed base 7 is located between the two mold clamping bases 5. The rotating plate 8 is rotatably connected inside the fixed base 7. The motor 10 is fixedly installed on one side of the outer wall of the fixed base 7. The output shaft of the motor 10 is fixedly connected to one side of the rotating plate 8. The rotating plate 8 is rotated by the operation of the motor 10. The fixed mold 9 is fixedly installed on one side of the outer wall of the rotating plate 8. After the first molding is completed, the rotating plate 8 rotates 180 degrees. At this time, the moving base 4 located on the right side of the fixed base plate 1 moves to the left along the slide rail 2, thereby combining the moving mold 6 and the fixed mold 9 to form a secondary molding mold. The second color material is injected into the cavity by the injection molding machine 18 to form a two-color soft and hard rubber product, thereby improving the injection efficiency of the injection mold.

[0031] The four corners of the outer wall of the moving mold 6 are provided with positioning rib grooves 13, and the four corners of the outer wall of the fixed mold 9 are fixedly installed with positioning ribs 16 that are adapted to the positioning rib grooves 13. When the moving mold 6 and the fixed mold 9 are closed, the positioning rib grooves 13 and positioning ribs 16 are used to make the moving mold 6 and the fixed mold 9 fit tightly together. A slide block 14 is fixedly installed on the outer wall of the fixed mold 9. Two combination molds 15 are slidably connected to the outer wall of the slide block 14. Multiple inclined grooves 17 are provided on the outer wall of the combination mold 15. Multiple inclined rods 12 that are adapted to the inclined grooves 17 are fixedly installed on the outer wall of the moving mold 6. When the moving mold 6 and the fixed mold 9 are closed, the inclined rods 12 are inserted into the inclined grooves 17. During this process, the two combination molds 15 move inward and towards each other along the slide block 14 to form a molding cavity. On the one hand, this increases the clamping force between the moving mold 6 and the fixed mold 9 to prevent the workpiece from producing burrs after molding. On the other hand, during the demolding process, the two combination molds 15 move outward to release the molding cavity and facilitate tool demolding.

[0032] Working principle:

[0033] During the injection molding process, the movable seat 4 located on the left side of the fixed base plate 1 moves to the right along the slide rail 2, thereby combining the moving mold 6 and the fixed mold 9 to form a primary molding mold. The injection molding machine 18 injects raw material into the primary molding mold to form a single-color hard rubber part. After the primary molding is completed, the rotating plate 8 rotates 180 degrees. At this time, the movable seat 4 located on the right side of the fixed base plate 1 moves to the left along the slide rail 2, thereby combining the moving mold 6 and the fixed mold 9 to form a secondary molding mold. The injection molding machine 18 injects the second color material into the cavity to form a two-color soft and hard rubber product, thereby improving the injection efficiency of the injection mold.
