Description

Technical Field

[0001] This utility model relates to a car floor mat, and more particularly to an injection mold for a car floor mat with metal pedals. Background Technology

[0002] Car floor mats are environmentally friendly automotive interior parts that integrate five main functions: water absorption, dust absorption, stain removal, and protection of the main carpet. As interior decorative items, car floor mats protect the cleanliness of the car's interior and exterior, serving an aesthetic and comfort-enhancing purpose.

[0003] However, existing car floor mats are prone to wear and tear in the pedal area due to frequent and repeated stepping. Therefore, it is necessary to install metal pedals in this area, and the installation of metal pedals requires a stable and reliable connection structure. Utility Model Content

[0004] To address the aforementioned issues, this utility model aims to provide an injection mold for a car floor mat with a metal pedal. The metal pedal is reliably positioned in the mold through an insert, and during the injection molding process, the molten plastic encapsulates and penetrates the metal pedal to form a single unit.

[0005] The technical solution of this utility model is an injection mold for a car floor mat with a metal pedal, including a core plate, a cavity plate, and a rectangular metal pedal. After the core plate and the cavity plate are closed, a closed product cavity is formed inside. The cavity plate is characterized by having an outwardly protruding pedal boss with a rectangular outer contour. The pedal boss has a first overflow groove distributed at intervals in the transverse direction. The core plate has an inwardly recessed rectangular groove corresponding to the pedal boss area. The outer ring of the rectangular metal pedal is bent to one side to form an annular bend. After the rectangular metal pedal is placed into the pedal boss, the top surface of the rectangular metal pedal is positioned with the rectangular groove through the annular bend, and the bottom surface of the rectangular metal pedal is in contact with the pedal boss for positioning. The rectangular metal pedal has a series of elongated holes in the middle. During injection molding, the molten plastic passes through the elongated holes and enters the first overflow groove to wrap around and fix the rectangular metal pedal.

[0006] Preferably, a second overflow groove is formed along the longitudinal direction of the pedal protrusion, and a third overflow groove with a shape adapted to the second overflow groove is formed in the rectangular groove. During injection molding, molten plastic enters the second overflow groove and the third overflow groove to wrap and fix the front and rear surfaces of the rectangular metal pedal.

[0007] Preferably, the second overflow groove diffuses in an arc shape to both sides when it is in the upper part of the pedal protrusion area, and the position and shape of the third overflow groove are adapted to the second overflow groove.

[0008] Preferably, the surface of the pedal boss is provided with positioning protrusions.

[0009] The metal pedal of this invention is reliably positioned in the mold by an insert, and is formed into a whole by molten plastic encapsulating and penetrating the metal pedal during the injection molding process, ensuring wear resistance at the pedal position. Attached Figure Description

[0017] The present invention will now be described in further detail with reference to the accompanying drawings.

[0018] like Figures 1 to 6As shown, this utility model provides an injection mold for a car floor mat with a metal pedal, including a core plate 1, a cavity plate 2, and a rectangular metal pedal 3. After the core plate 1 and the cavity plate 2 are closed, a closed product cavity is formed inside. The cavity plate 2 is provided with a pedal boss 21 with an outwardly protruding rectangular outline. The pedal boss 21 is provided with first overflow grooves 22 distributed laterally. The core plate 1 is provided with a rectangular groove 11 that is recessed inward in the area corresponding to the pedal boss 21. The outer ring of the rectangular metal pedal 3 is bent to one side to form an annular bending part 31. After the rectangular metal pedal 3 is placed into the pedal boss 21, the top surface of the rectangular metal pedal 3 is positioned with the rectangular groove 11 through the annular bending part 31, and the bottom surface of the rectangular metal pedal 3 is in contact with the pedal boss 21 for positioning. The rectangular metal pedal 3 is provided with a series of elongated holes 32 in the middle. During injection molding, the molten plastic passes through the elongated holes 32 and enters the first overflow groove 22 to wrap around and fix the rectangular metal pedal 3.

[0019] In the above scheme, a second overflow groove 23 is formed on the pedal boss 21 along the longitudinal direction, and a third overflow groove 12 with a shape adapted to the second overflow groove 23 is formed in the rectangular groove 11. During injection molding, the molten plastic enters the second overflow groove 23 and the third overflow groove 12 to wrap and fix the front and rear surfaces of the rectangular metal pedal 3.

[0020] Furthermore, the second overflow groove 23 spreads outward in an arc shape to both sides when it is in the upper region of the pedal boss 21, and the position and shape of the third overflow groove 12 are adapted to the second overflow groove 23.

[0021] In addition, the surface of the pedal boss 21 is provided with a positioning protrusion 211, which contacts the bottom surface of the rectangular metal pedal 3.

[0022] This invention provides a rectangular metal pedal 3 in the pedal area of ​​a car floor mat. The rectangular metal pedal 3 has an annular bend 31 and an elongated hole 32. A pedal boss 21, a first overflow groove 22, and a second overflow groove 23 are provided in the corresponding area of ​​the cavity plate 2. A rectangular groove 11 and a third overflow groove 12 are provided on the core plate 1. This fixes the rectangular metal pedal 3 and ensures that the molten plastic wraps around the rectangular metal pedal 3 after passing through the elongated hole 32 during the injection molding process, thus forming an effective integrated structure of the car floor mat and the rectangular metal pedal 3.

[0023] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the utility model. Any simple modifications, equivalent changes, or alterations made to the above embodiments based on the technical principles of the present utility model shall still fall within the scope of the technical solution of the present utility model.
