Description

Technical Field

[0001] This utility model belongs to the field of front bumper mold technology, and relates to a pull-out slider device for front bumper molds of electric four-wheeled vehicles. Background Technology

[0002] The front bumper of a four-wheeled vehicle is a device that absorbs and mitigates external impacts, protecting the front and rear of the vehicle. It acts as a buffer when the four-wheeled vehicle or driver is subjected to impact. Plastic bumpers are a common type of bumper, generally made of polyester or polypropylene materials, and manufactured using injection molding; for example, a front bumper mold disclosed in patent number CN202311872034.5.

[0003] The pull-out slider is an important component in injection molds, mainly used to solve the demolding problem of products with side undercuts or concave structures. However, the front bumper of a four-wheeled vehicle has a concave opening. The disadvantage of traditional pull-out sliders is that they are located inside the mold, resulting in a larger overall mold size, increased weight, and inconvenient mold opening. Moreover, the movement of the pull-out slider device can only be realized after the mold is opened. Therefore, we designed a pull-out slider device for the front bumper mold of an electric four-wheeled vehicle. Summary of the Invention

[0004] The purpose of this utility model is to provide a pull-out slider device for the front bumper mold of an electric four-wheeled vehicle, so as to solve the problems mentioned in the background art.

[0005] The objective of this utility model can be achieved through the following technical solution: a pull-out slider device for a front bumper mold of an electric four-wheeled vehicle, comprising an upper mold body, a lower mold body, two mold side plates, two mold forming inserts, and a mold base plate. The two sides of the lower mold body are connected to the two mold forming inserts by bolts. The upper mold body of the bumper is closed and connected to the lower mold body and the two mold forming inserts. A mold top plate is provided at the top of the upper mold body of the bumper. It also includes two side-pulling sliding blocks. The side-pulling sliding blocks are connected to the two mold side plates so that the two mold side plates are located at the bottom of the lower mold body. The two side-pulling sliding blocks slide on the top of the mold base plate. Each of the tops of the two side-pulling sliding blocks is provided with a stepped portion. The mold forming inserts are located at the corresponding stepped portions and form strip-shaped limiting portions. The strip-shaped limiting portions are connected to the bottom of the upper mold body of the bumper.

[0006] In the aforementioned pull-out slider device for the front bumper mold of an electric four-wheeled vehicle, an opening base plate is provided at the center of the top of the mold base plate. Anti-retraction feet are provided at each of the four corners of the opening base plate. An integrally formed protruding connecting part is provided in the center of the two side-pulling sliding blocks. Each protruding connecting part forms two connecting recesses with the side-pulling sliding block, and the four anti-retraction feet are located within these connecting recesses. The purpose of this design is to allow the mold core insert and the opening cylinder to be installed on the opening base plate, enabling the lifting, core-pulling, and demolding movement, while simultaneously preventing the side-pulling sliding blocks from retracting during the core-pulling process.

[0007] In the aforementioned pull-out slider device for the front bumper mold of an electric four-wheeled vehicle, recessed positioning parts are provided in the middle of both sides of the mold opening base plate, and the two recessed positioning parts are connected to the two protruding connecting parts. The purpose of this design is to achieve a good positioning effect, so that the side pull-out slider can be accurately assembled into the mold opening base plate, mold forming inserts, and other mold components.

[0008] In the aforementioned pull-out slider device for the front bumper mold of the electric four-wheeled vehicle, the bottom ends of both side-pulling sliders are provided with integrally formed protrusions, and the top sides of the mold base plate are provided with corresponding strip-shaped openings for the protrusions. This design aims to increase the connection stability of the side-pulling sliders and ensure a firm connection with the mold base plate.

[0009] In the aforementioned pull-out slider device for the front bumper mold of an electric four-wheeled vehicle, each side pull-out slider has insert connecting posts on both sides of its opening. The side pull-out slider is connected to the parting surface of the mold forming insert through two insert connecting posts. Each anti-retrograde support foot has a post cavity on its side located on the mold opening base plate, and the post cavity limits the insertion connecting posts. The purpose of this design is to better connect the side pull-out slider to the parting surface of the mold forming insert, thus achieving the separation effect of the formed front bumper during the pull-out separation process.

[0010] Compared with the prior art, the advantages of the pull-out slider device of the electric four-wheeled vehicle front bumper mold of this utility model are as follows: by setting two side pull-out sliders, each with a stepped top, the mold forming insert is located at the corresponding stepped part and forms a strip-shaped limiting part, which is connected to the bottom end of the upper mold body of the bumper. Insert connecting pillars are set on both sides of the opening of the side pull-out slider. The side pull-out slider is connected to the parting surface of the mold forming insert through the two insert connecting pillars. By adopting the side pull-out method, the front bumper and the mold forming insert can be separated better, and the overall mold volume is small, making mold opening very convenient.
