Description

Technical Field

[0001] This utility model relates to the field of automotive wheel arch injection molding technology, specifically a pushing device for automotive wheel arch injection molds. Background Technology

[0002] Wheel arches, also known as wheel covers or fenders, are an important component of a car's body structure. Located above the wheels, they serve to protect and decorate them. The primary function of wheel arches is to provide space for the wheels, brakes, and suspension system, preventing these components from being impacted by obstacles during movement, and also protecting the vehicle from mud, sand, and other debris. The shape and size of wheel arches are typically determined by the wheel size and the car's design. They can be made of stamped metal, plastic, or other composite materials.

[0003] Authorization announcement number CN222328955U discloses a molding die for automotive wheel arches. The technical solution is as follows: "It includes an upper die, a drive seat mounted on the bottom of the upper die, and the drive seat covers the surface of a lower die. The bottom of the lower die is fixedly connected to a base, and the drive seat is fixedly connected to an edge mold core. A mold cavity is formed inside the upper die; demolding pillars are fixedly mounted at both ends of the drive seat." The beneficial effects are: it allows for rapid demolding of wheel arch products, improving the molding efficiency of the die; it eliminates the need for a separate drive source to drive the product for demolding, directly reducing the product's mold-making cost.

[0004] The above technical solution has the following defects: it lacks a demolding structure for the car wheel cover. Because the car wheel cover shrinks after molding and cooling, the edge mold core will be tightly combined with the wheel cover, which makes demolding difficult and easily causes the wheel cover to deform or be damaged, affecting product quality and production efficiency. Therefore, a pushing device for the injection mold of car wheel cover is proposed to solve the problems mentioned above. Utility Model Content

It solves the problem that existing automotive wheel cover molding molds lack a separation structure, and the edge mold core is tightly combined with the wheel cover, making demolding difficult and causing wheel cover deformation or damage if forced demolding is performed.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A pushing device for an injection mold for an automobile wheel cover includes a base plate, a lower mold and an upper mold. The top of the base plate is provided with a lifting mounting assembly for lifting the upper mold, and the top of the base plate is provided with a demolding structure for demolding the automobile wheel cover.

[0024] Please see Figures 1 to 3 The present embodiment of a pushing device for an injection mold for an automobile wheel cover includes a base plate 1, a lower mold 4 and an upper mold 5. The top of the base plate 1 is provided with a lifting and mounting assembly for lifting the upper mold 5, and the top of the base plate 1 is provided with a demolding structure for demolding the automobile wheel cover.

[0025] The upper mold 5 is movably mounted on the top of the lower mold 4, the base 3 is fixedly mounted on the top of the base plate 1, and an injection check valve 9 is fixedly mounted on the top of the upper mold 5.

[0026] In this embodiment, the lifting and mounting assembly includes a side plate 6 fixedly mounted on the top of the base plate 1, a top plate 7 fixedly mounted on the top of the side plate 6, a cylinder 8 fixedly mounted on the top of the top plate 7, two support plates 2 fixedly mounted on the bottom of the base plate 1, and the bottom end of the telescopic shaft of the cylinder 8 fixedly mounted on the top of the upper mold 5.

[0027] It should be noted that cylinder 8 will drive the upper mold 5 to lift and adjust its height.

[0028] In this embodiment, a cooling water inlet hose 19 is fixedly installed on the top of the upper mold 5, and a cooling water outlet hose 20 is fixedly installed on the top of the upper mold 5. A flow groove is opened inside the upper mold 5, and both the cooling water inlet hose 19 and the cooling water outlet hose 20 are connected to the flow groove.

[0029] It should be noted that cooling water is introduced into the upper mold 5 through the cooling water inlet hose 19. The cooling water will quickly cool down the car wheel cover, which will facilitate the rapid forming of the car wheel cover. The cooling water is discharged through the cooling water outlet hose 20.

[0030] In this embodiment, the demolding structure includes a base 3 fixedly installed at the bottom of the lower mold 4, a mold core 10 rotatably installed at the top of the lower mold 4, a rotating shaft 11 fixedly installed at the bottom of the mold core 10, a limiting ring 12 fixedly installed on the outer peripheral wall of the rotating shaft 11, the rotating shaft 11 passing through the interior of the base 3 and the lower mold 4, an adjustment hole is provided on the base plate 1, the rotating shaft 11 is rotatably connected to the interior of the adjustment hole, and the limiting ring 12 is rotatably connected to the top of the base plate 1.

[0031] It should be noted that the rotating shaft 11 will drive the mold core 10 and the car wheel cover to rotate and adjust the angle.

[0032] In this embodiment, a limiting rod 13 is fixedly installed on the outer peripheral wall of the limiting ring 12, and a limiting stop 14 is fixedly installed on the inner left and inner right walls of the base 3. Two adjusting rods 15 are fixedly installed on the outer peripheral wall of the rotating shaft 11. An mounting plate 16 is fixedly installed on the top of the base plate 1. A push rod 17 is slidably connected inside the mounting plate 16. A separating blade 18 is fixedly installed on the left end of the push rod 17. A sliding hole is opened inside the mounting plate 16. The adjusting rod 15 is slidably connected inside the sliding hole. The size of the adjusting rod 15 is adapted to the sliding hole. The separating blade 18 and the mold core 10 are located on the same horizontal plane.

[0033] It should be noted that the limit stop 14 and the limit rod 13 limit the rotating shaft 11, so that the maximum angle of rotation of the mold core 10 to drive the car wheel cover is 180 degrees.

[0034] It should be noted that the separating blade 18 separates and cuts the bottom of the car wheel cover from the connection point of the lower mold 4, making it easier to demold the car wheel cover.

[0035] The working principle of the above embodiments is as follows:

[0036] After the car wheel cover cools and forms, the cylinder 8 drives the upper mold 5 to move upward. When the upper mold 5 separates from the lower mold 4, the worker pushes the push rod 17 to the left, and the separating blade 18 moves to the left at the same time. At this time, the separating blade 18 will cut the connection between the car wheel cover and the lower mold 4, and also cut the connection between the mold core 10 and the car wheel cover. Then, the adjusting rod 15 is rotated to drive the rotating shaft 11 to rotate 180 degrees. Then, the separating blade 18 is pushed again to cut the car wheel cover from the lower mold 4 and the mold core 10. At this time, the car wheel cover can be moved upward to demold it.

[0037] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods, and any method that achieves the desired beneficial effect can be implemented. Furthermore, all electrical components in this embodiment are electrically connected to the main controller and power supply. The main controller can be a conventional, known device such as a computer that performs control functions. Those skilled in the art can control the electrical components through simple programming, and the existing disclosed power connection technologies are common knowledge in the field. Therefore, this embodiment will not elaborate further on their specific structural composition and working principles.
