Description

Technical Field

[0001] This utility model relates to the field of landscaping technology, specifically a foaming mold frame for automotive parts. Background Technology

[0002] Foaming molds are an indispensable part of the foaming process. They are usually made of high-strength materials and can withstand the pressure and temperature generated during the foaming process. The design of the mold needs to be customized according to the shape, size and production requirements of the product to ensure that the foamed product has the required appearance and quality. Foaming molds are widely used in many fields, such as automobiles, home appliances and construction. In the automotive industry, foaming molds are used to manufacture interior parts such as seats and dashboards. These parts can achieve better comfort and shock absorption performance through the foaming process.

[0003] In the prior art, such as the automotive parts foaming mold frame proposed in patent application number "CN202020332143.3", an upper limit sensor corresponding to the top of the upper mold frame is set on the guide rod above the upper mold frame. The lower limit sensor and the upper limit sensor are used to detect the descent and rise of the upper mold frame, respectively. The upper mold frame moves horizontally up and down relative to the lower mold frame under the drive of the lead screw. When opened, the upper mold moves horizontally upward relative to the lower mold, which can effectively prevent the upper mold from scratching the foamed product and ensure the quality of the foamed product.

[0004] However, in the aforementioned patent application, when using a foaming mold frame to manufacture automotive parts, it is necessary to inject the raw material into the mold in the foaming mold frame and rotate it so that the raw material is evenly distributed in the mold. However, due to the need for rotation, the mold needs to withstand different placement angles. After the mold is closed, it is easy for the closure to be not tight or for the parts to age, which will lead to insufficient sealing performance. During the rotation process, the raw material is easy to leak, affecting the quality of the finished product. Utility Model Content

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0029] A foaming mold for automotive parts, such as Figures 1-6 As shown, the device includes a bracket 1. Inside the bracket 1, near the upper end, a main body 2 is rotatably connected via a shaft. The outer wall of the main body 2 is rotatably connected via a shaft to a flipping body 3. The top of the flipping body 3 is fixedly connected to an upper mold 4. The bottom of the main body 2 is fixedly connected to a lower mold 5. A sealing mechanism is provided inside the main body 2. An auxiliary mechanism is provided on the bottom surface of the main body 2. The sealing mechanism includes two outer shells 16 and two outer shells 18. Both outer shells 16 and two outer shells 18 are movably installed inside the main body 2, and the two outer shells 18 are slidably connected between the two outer shells 16. Two sliding grooves are opened at the bottom of the main body 2, and reciprocating screws 6 are rotatably connected inside each of the two sliding grooves.

[0030] The upper mold 4 is equipped with an injection pipe and a sealing cap for introducing foaming raw materials for making automotive parts.

[0031] Two T-shaped movable plates 7 are fitted on the outside of the two reciprocating screws 6 and near both ends. The upper end of the T-shaped movable plates 7 is fixedly connected to the outer shell 16. Two motors are installed on the outer side wall of the main body 2 near the bottom end. The output ends of the two motors are respectively connected to the two reciprocating screws 6. Several threads are opened on the inner wall of the T-shaped movable plate 7 where it is fitted with the reciprocating screw 6. When the reciprocating screw 6 rotates, the T-shaped movable plate 7 can slide along the outside of the reciprocating screw 6 under the cooperation of the threads and the limiting of the sliding groove.

[0032] Fixing nails 17 are inserted into the upper surface of both outer shells 16 near both ends. Fixing holes are opened on the upper surface of the second outer shell 18 near both ends, and the fixing holes fit with the fixing nails 17. By passing each fixing nail 17 through the outer shell 16 and inserting it into the corresponding fixing hole, the position of the second outer shell 18 can be fixed.

[0033] Both outer shells 16 have a movably installed sealing plate 19 inside, and both outer shells 18 have a movably installed sealing plate 20 inside. Several telescopic push rods 22 are installed between the outer wall of sealing plate 19 and the inner wall of outer shell 16, and between the inner wall of outer shell 18 and the outer wall of sealing plate 20. Each telescopic push rod 22 is fitted with a support spring. Under the action of the rebound force of the support spring, the sealing plate 19 can be moved to the outer wall of the upper mold 4 and the lower mold 5 to squeeze and fill the gap between the upper mold 4 and the lower mold 5. Both sealing plate 19 and sealing plate 20 are made of rubber. After being squeezed, they can deform and thus fill the gap between the upper mold 4 and the lower mold 5 well to seal.

[0034] A motor is installed on the outer side wall of the bracket 1 near the upper end, and the output end of the motor is connected to the main body 2. Two cylinders 10 are installed on the back of the main body 2, and the ends of the two cylinders 10 away from the main body 2 are fixedly connected to the flipping body 3.

[0035] In use, two cylinders 10 drive the flipping body 3 to close onto the main body 2, causing the upper mold 4 and lower mold 5 to close together. Then, the raw material is fed into the upper mold 4 and lower mold 5. At this time, two motors drive two reciprocating screws 6 to rotate, causing two T-shaped movable plates 7 to slide along the outside of the reciprocating screws 6 and move closer together. This causes the two outer shells 16 to move and move closer together, so that the sealing plates 19 installed inside the two outer shells 16 are tightly pressed against the outer side walls of the upper mold 4 and lower mold 5 respectively. As the outer shells 16 continue to move, the sealing plates 19 move towards the inside of the outer shells 16, shortening the telescopic push rod 22. The support spring is compressed and contracted, and under the action of the support spring's rebound force, the sealing plates 19 move and press against the outer walls of the upper mold 4 and lower mold 5, filling the gap between the upper mold 4 and lower mold 5. Then, the outer shell 2 18 is moved along the inside of the two outer shells 1 16, so that the sealing plate 2 20 is pressed tightly against the flipping body 3 and the other outer wall of the upper mold 4. Similarly, with the telescopic push rod 22 and support spring installed inside the outer shell 2 18, the gap between the other outer wall of the upper mold 4 and the lower mold 5 can be filled. After adjustment, the position of the outer shell 2 18 can be fixed by inserting each fixing nail 17 through the outer shell 1 16 into the corresponding fixing hole. This can fully fill the gap between the upper mold 4 and the lower mold 5, avoiding gaps that could lead to insufficient sealing, material leakage, and affect the quality of the final product. At this time, the motor 3 can drive the main body 2 and the flipping body 3 to rotate as a whole, which in turn drives the flipping body 3 and the upper mold 4 to rotate, so that the material is evenly distributed inside the flipping body 3 and the upper mold 4, allowing the material to be better shaped for the production of automotive parts.

[0036] like Figures 3-4As shown, the auxiliary mechanism includes a connecting frame 9, which is fixedly connected to the bottom of the main body 2. Two mounting plates are fixedly installed inside the bottom of the connecting frame 9. An elliptical block 12 is rotatably connected between the outer walls of the two mounting plates via a shaft. A motor 2 is installed on the outer wall of one of the mounting plates, and the output end of the motor 2 is connected to the elliptical block 12.

[0037] Vertical rods 21 are fixedly installed inside the connecting frame 9 near both sides. A slide plate 8 is sleeved between the two vertical rods 21. A connecting rod 13 is fixedly connected to the upper surface of the slide plate 8. A push block 15 is fixedly connected to the upper end of the connecting rod 13, and the push block 15 is movably installed at the bottom of the lower mold 5. Support springs are sleeved on the outside of the two vertical rods 21 and between the bottom surface of the slide plate 8 and the bottom of the connecting frame 9. Several rollers 24 are rotatably connected to the bottom surface of the slide plate 8 through a shaft. The rollers 24 contact the outer wall of the elliptical block 12, which can effectively reduce the friction between the elliptical block 12 and the slide plate 8 when the elliptical block 12 rotates, so that the elliptical block 12 can better push the slide plate 8 up. The two support springs play a supporting role for the slide plate 8.

[0038] Specifically, after the raw material is formed, the flipping body 3 and the upper mold 4 are reset, and the flipping body 3 is rotated by the cylinder 10, which moves the upper mold 4 out of the lower mold 5. At this time, the elliptical block 12 can be rotated 90° by the motor 2, which can push the slide plate 8 to move up along the two vertical rods 21, and move the push block 15 up, pushing the raw material formed in the lower mold 5 upward, so that the raw material is automatically separated from the lower mold 5, which is convenient for the staff to demold.

[0039] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
