Description

Technical Field

[0001] The utility model relates to the field of automobile floor mat production molds, in particular to a high-strength and wear-resistant automobile floor mat injection molding mold. Background Art

[0002] Car floor mats can be laid inside the car to absorb dust, waterproof and soundproof. While protecting the vehicle, they can also be used for interior decoration and are widely used.

[0003] To improve waterproofing, one-piece injection-molded plastic floor mats can be used. Although mold costs for plastic floor mats are high, the production efficiency after mold opening is high, making them suitable for mass production. Car floor mats need to bend to facilitate installation and removal from the vehicle, so they require good flexibility. Soft plastics are typically used for injection molding, but this results in low local strength, especially in the area under the driver's feet, which suffers from poor wear resistance and needs improvement. Utility Model Content

[0004] The purpose of the utility model is to provide a high-strength and wear-resistant automobile floor mat injection molding mold to strengthen the local structure and improve the wear resistance and production efficiency.

[0005] To achieve this purpose, the present invention adopts the following technical solutions:

[0006] A high-strength, wear-resistant car floor mat injection molding mold, comprising: an anti-slip wear-resistant plate, a movable plate and a fixed plate, the movable plate being located in front of the fixed plate, a core insert being provided on the front of the movable plate, a car floor mat molding cavity corresponding to the core insert being concavely provided on the front of the fixed plate, the anti-slip wear-resistant plate being arranged in the car floor mat molding cavity, a positioning blind hole being provided on the back of the anti-slip wear-resistant plate, anti-slip grooves being provided at intervals on the front of the anti-slip wear-resistant plate, and positioning ribs corresponding one-to-one to the anti-slip grooves being provided on the front of the core insert.

[0007] Wherein, a positioning pin corresponding to the positioning blind hole is provided in the molding cavity of the automobile floor mat.

[0008] Wherein, the number of the positioning blind holes is at least 2.

[0009] Wherein, the positioning rib and the core insert adopt an integrated steel structure.

[0010] Wherein, the anti-skid and wear-resistant plate is made of hard plastic plate or aluminum alloy plate.

[0011] The car mat forming cavity is provided with a flow channel behind the anti-skid and wear-resistant plate, and the back of the anti-skid and wear-resistant plate is concavely provided with a groove in front of the flow channel.

[0012] Wherein, the groove extends to the edge of the anti-slip and wear-resistant plate.

[0013] The beneficial effects of the utility model are as follows: a high-strength and wear-resistant automobile floor mat injection molding mold, which positions the anti-skid wear-resistant plate in the automobile floor mat molding cavity through the cooperation of positioning blind holes and positioning pins, and uses soft plastic to fix the anti-skid wear-resistant plate on the automobile floor mat during the injection molding process of the automobile floor mat. The structure is stable, and the positioning ribs are used to fill the anti-skid groove to avoid the problem of soft plastic entering the anti-skid groove, ensuring the anti-skid effect. The anti-skid wear-resistant plate is prefabricated with hard plastic plate or aluminum alloy plate, with high strength, which improves the wear resistance of the area under the driver's feet and the production efficiency of the automobile floor mat.

[0016] Figure 3 yes Figure 2 A partial enlarged view of part A. DETAILED DESCRIPTION

[0017] The following combination Figures 1 to 3 The technical solution of the present utility model is further illustrated by specific embodiments.

[0018] like Figures 1 to 3 The high-strength and wear-resistant car floor mat injection molding mold shown includes: an anti-slip and wear-resistant plate 6, a movable template 1 and a fixed template 2. The movable template 1 is located in front of the fixed template 2. The movable template 1 moves relative to the fixed template 2 under the drive of the hydraulic cylinder to realize mold opening and closing actions.

[0019] A core insert 3 is provided on the front of the movable template 1, and a car mat forming cavity 4 corresponding to the core insert 3 is provided in the front of the fixed template 2. Figure 2 As shown, after the mold is closed, injection molding is performed to achieve the molding of the car mat in the car mat molding cavity 4.

[0020] In order to improve local wear resistance, the anti-slip wear-resistant plate 6 is arranged in the automobile floor mat forming cavity 4, and a positioning blind hole 9 is provided on the back of the anti-slip wear-resistant plate 6. In this embodiment, the automobile floor mat forming cavity 4 is provided with positioning pins 5 corresponding to the positioning blind holes 9, and the number of the positioning blind holes 9 is at least 2. The anti-slip wear-resistant plate 6 is positioned in the automobile floor mat forming cavity 4 through the cooperation of the positioning blind holes 9 and the positioning pins 5, so that the anti-slip wear-resistant plate 6 is located in the area under the driver's feet on the automobile floor mat, thereby improving the structural strength and wear resistance of this area.

[0021] After mold closing, injection molding is performed, and soft plastic is used to fix the anti-skid wear-resistant plate 6 on the car mat during the injection molding process, so that the structure is stable. In this embodiment, the anti-skid wear-resistant plate 6 is prefabricated with a hard plastic plate or an aluminum alloy plate, which has high strength and good wear resistance.

[0022] A flow channel 10 is provided in the car floor mat molding cavity 4 and is located behind the anti-slip and wear-resistant plate 6. A groove 7 is provided on the back side of the anti-slip and wear-resistant plate 6 and is located in front of the flow channel 10. In this embodiment, the groove 7 extends to the edge of the anti-slip and wear-resistant plate 6. The soft plastic enters the groove 7 through the flow channel 1 and enters the car floor mat molding cavity 4 through the groove 7, thereby wrapping and fixing the edge of the anti-slip and wear-resistant plate 6, and the structural stability is high.

[0023] Anti-skid grooves are spaced apart on the front of the anti-skid wear-resistant plate 6, enhancing the anti-skid effect. Positioning ribs 8 are provided on the front of the core insert 3, corresponding one-to-one with the anti-skid grooves. After the mold is closed, the positioning ribs 8 fill the anti-skid grooves, preventing soft plastic from entering the anti-skid grooves during the injection molding process and improving the quality of the injection molding. In this embodiment, the positioning ribs 8 and the core insert 3 utilize an integrated steel structure, providing high strength and structural stability.
