Description

Technical Field

[0001] This utility model belongs to the technical field of core-pulling mechanism, and relates to a core-pulling forming mechanism for multi-buckle large slider of electric vehicle front turn signal frame. Background Technology

[0002] The front turn signal of an electric vehicle is an important component used on electric vehicles. It includes a frame structure. Since the frame has multiple clips, it is usually injection molded and the core is pulled out and demolded using a large slider.

[0003] Existing technology, such as the dual-color molding slider core-pulling mechanism disclosed in patent publication number CN206106270U, ​​includes a first inclined guide block, a second inclined guide block, and a slider assembly. The upper end of the first inclined guide block is fixed to the first fixed mold, and its lower end is provided with a first guide slope. The upper end of the second inclined guide block is fixed to the second fixed mold, and its lower end is provided with a second guide slope. Guide strips extend outward from both sides of the second guide slope. The slider assembly includes a slider body and a locking block. The slider body has a guide groove in the vertical direction, through which the first and second inclined guide blocks can pass and move up and down. Locking block mounting seats are provided on both sides of the slider body. The locking blocks are disposed in the locking block mounting seats and extend out of the guide grooves, pressing the first and second inclined guide blocks together. This solution simplifies the mold structure, improves the reliability of mold operation, and reduces the manufacturing cost of the mold, demonstrating ingenious design.

[0004] The drawback of the aforementioned core-pulling mechanism is that the accuracy of the reset cannot be guaranteed when the slider needs to be reset after core pulling. To address this, we have designed a multi-buckle large slider core-pulling forming mechanism for the front turn signal frame of electric vehicles. Summary of the Invention

[0005] The purpose of this utility model is to provide a multi-buckle large slider core-pulling molding mechanism for the front turn signal frame of electric vehicles, so as to solve the problems mentioned in the background art.

[0006] The purpose of this utility model can be achieved through the following technical solution: a multi-buckle large slider core-pulling forming mechanism for electric vehicle front turn signal frame, including a large core-pulling slider, an inclined guide rod mounting seat, and an inclined guide rod. The tail end of the inclined guide rod is connected to the inclined guide rod mounting seat by bolts. A through hole is provided on one side of the large core-pulling slider. A stepped forming surface and a sliding contact surface are provided at the top of the large core-pulling slider. The inclined guide rod is inserted into the through hole. The system also includes a slider reset seat. A reset mounting hole is provided on one side of the bottom end of the large core-pulling slider. The slider reset seat is connected to the large core-pulling slider through the reset mounting hole. A bent part is provided on one side of the slider reset seat. A snap-fit ​​connection part is provided at the end of the bent part.

[0007] In the aforementioned multi-snap-fit ​​large slider core-pulling forming mechanism for the front turn signal frame of an electric vehicle, the large core-pulling slider consists of a first slider part and a second slider part, which are fastened together. The stepped forming surface and the sliding contact surface are located on the top surfaces of the first slider part and the second slider part, respectively. This design facilitates better use of the large core-pulling slider, ensuring that there is no interference between the forming part and the sliding part of the large slider.

[0008] In the aforementioned multi-snap large slider core-pulling forming mechanism for the front turn signal frame of an electric vehicle, the two ends of the bent portion are provided with edge mating portions, and the two ends of the reset mounting hole are provided with edge grooves corresponding to the edge mating portions. This design aims to ensure good contact accuracy between the reset mounting hole and the slider reset seat, preventing structural protrusions.

[0009] In the aforementioned multi-snap large slider core-pulling forming mechanism for the front turn signal frame of an electric vehicle, a guide bearing ring is installed inside the through hole. The inner ring of the guide bearing ring is guided and connected to the outer wall of the inclined guide rod. A lubrication part is provided at the outer ring of the guide bearing ring, and the lubrication part is in close contact with the inner wall of the through hole. The purpose of this arrangement is to provide good guidance and lubrication, and to reduce wear on the inclined guide rod during the core-pulling process.

[0010] In the aforementioned multi-clamp large slider core-pulling forming mechanism for the front turn signal frame of an electric vehicle, a positioning notch is provided on the side of the inclined guide rod mounting seat. This design facilitates better positioning and engagement of the inclined guide rod mounting seat.

[0011] In the aforementioned multi-snap large slider core-pulling forming mechanism for the front turn signal frame of an electric vehicle, a bolt connection through hole is provided on one side of the slider reset seat, and a positioning bolt is installed inside the bolt connection through hole. This design facilitates better locking of the slider reset seat and prevents loosening.

[0012] Compared with the prior art, the advantages of the multi-buckle large slider core-pulling forming mechanism for the front turn signal frame of electric vehicles of this utility model are as follows: by setting a slider reset seat, a reset mounting hole is opened at the bottom of the large core-pulling slider, the slider reset seat is connected to the large core-pulling slider through the reset mounting hole, a bent part is set on one side of the slider reset seat, and a snap-fit ​​connection part is set at the end of the bent part. In this way, after the large core-pulling slider is reset, it has good positional accuracy, eliminates the need for subsequent position calibration operations, and is convenient to use.
