Description

Technical Field

[0001] This utility model belongs to the technical field of demolding mechanisms, and relates to a small inclined demolding mechanism for electric vehicle headlight covers. Background Technology

[0002] Electric vehicle helmets, also known as safety helmets, protect the driver's head and provide cushioning in the event of a traffic accident. The production of electric vehicle helmets requires the use of an integrated injection molding mold.

[0003] Because electric vehicle headgear has an inverted part, a slanted ejector is usually used for demolding. For example, in the case of a mold demolding slanted ejector mechanism disclosed in patent publication number CN206623348U, a slanted ejector includes a slanted ejector, a slanted ejector base, and a slanted ejector guide. This mechanism rotatably connects a square slanted ejector to a sliding plate, allowing the slanted ejector to slide back and forth in the T-shaped track groove on the slanted ejector base while simultaneously swinging around a rotation axis, achieving one sliding degree of freedom and one swinging degree of freedom. This prevents the slanted ejector from jamming during operation, and the design angle can reach 15 degrees, improving the service life of the mechanism and expanding the application range of the slanted ejector. However, this solution has a drawback: the slanted ejector base needs to be installed with the mold, mostly using a sliding installation method, which lacks a reset effect. Therefore, we designed a small slanted ejector demolding mechanism for electric vehicle headgear. Summary of the Invention

[0004] The purpose of this invention is to provide a small inclined ejector mechanism for electric vehicle headlights 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 small inclined ejector demolding mechanism for electric vehicle headgear, comprising a headgear injection mold and an electric vehicle headgear injection molded part. The electric vehicle headgear injection molded part is formed in the molding cavity of the headgear injection mold. A sliding opening is provided in the middle of both sides of the headgear injection mold. Two molding connecting blocks are provided inside the sliding opening. An inclined ejector connecting seat is installed at the bottom end of each of the two molding connecting blocks. A spring opening is provided at one end of each of the two inclined ejector connecting seats. A spring part is installed inside each of the two spring openings.

[0006] In the aforementioned electric vehicle headgear small inclined ejector demolding mechanism, the bottom end of each molding connecting block is connected to the inclined ejector connecting seat by bolts. Each inclined ejector connecting seat is slidably disposed inside a corresponding sliding opening. The top end of each inclined ejector connecting seat is slidably connected to an inclined ejector rod through a guide hole. Each inclined ejector rod has a limiting recess on its side, which limits the movement of the headgear injection mold. The purpose of this design is to use bolts to install the molding connecting block and the inclined ejector connecting seat, making them a single unit, and to provide a good limiting effect during the upward inclined movement of the inclined ejector connecting seat.

[0007] In the aforementioned electric vehicle headgear small angled ejector demolding mechanism, each of the molding connecting blocks is equipped with a molding contact seat on its side, and one side of the molding contact seat is provided with an undercut molding contour surface. The purpose of this arrangement is to facilitate better docking with the undercut part of the electric vehicle headgear injection molded part, and to ensure good mold opening accuracy during the angled ejector mold opening process.

[0008] In the aforementioned electric vehicle headgear small angled ejector demolding mechanism, stepped portions are installed on both sides of the top of the angled ejector connecting seat, and angled ejector seat limiting strips are installed at the upper ends of the two stepped portions. The angled ejector seat limiting strips are connected to the headgear injection mold. The purpose of this design is to use the angled ejector seat limiting strips to ensure that the angled ejector connecting seat can slide at the sliding opening without disengaging from the sliding opening, thus ensuring the effectiveness of the sliding.

[0009] In the aforementioned electric vehicle headgear small inclined ejector demolding mechanism, inclined ejector seat limiting blocks with corresponding sliding openings are provided on both sides of the headgear injection mold, and the inclined ejector connecting seat makes limiting contact with the inclined ejector seat limiting blocks. The purpose of this setting is to limit the initial position of the inclined ejector connecting seat, making it easier to determine the sliding stroke of the inclined ejector connecting seat.

[0010] In the aforementioned electric vehicle headgear small inclined ejector demolding mechanism, a telescopic cylinder is installed at the bottom platen of the headgear injection mold. The telescopic cylinder drives the electric vehicle headgear injection part to separate from the molding cavity of the headgear injection mold. The purpose of this arrangement is to use the telescopic cylinder to lift the electric vehicle headgear injection part from the molding cavity, thereby realizing the mold opening and demolding operation.

[0011] Compared with the prior art, the advantages of the electric vehicle headgear small inclined ejector demolding mechanism of this utility model are as follows: by opening a spring opening at one end of the inclined ejector connecting seat, a spring part is installed inside the spring opening. The spring part is connected to the non-forming cavity part of the headgear injection mold to produce a resisting effect. After the inclined ejector demolds, the spring part is compressed and stores energy. After demolding is completed, the limiting force disappears, and the stored energy is released, which allows the inclined ejector connecting seat to return to the initial state, which facilitates subsequent injection molding operations.

[0018] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0019] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, this utility model relates to a small inclined ejector mechanism for electric vehicle headgear demolding.

[0020] Example 1: The small inclined ejector demolding mechanism includes a head cover injection mold 1 and an electric vehicle head cover injection mold 2. The head cover injection mold 1 is an injection mold in the prior art, including common mold components such as upper mold and lower mold, which will not be described in detail here.

[0021] The electric vehicle head cover injection molded part 2 is formed in the molding cavity of the head cover injection mold 1. A sliding opening 8 is opened in the middle of both sides of the head cover injection mold 1. The interior of the sliding opening 8 is laterally connected to the inclined top connecting seat 4. A molding connecting block 3 is set at the top of the inclined top connecting seat 4. The bottom end of each molding connecting block 3 is connected to the inclined top connecting seat 4 by bolts. This ensures that the connection between the molding connecting block 3 and the inclined top connecting seat 4 has good stability, and the two become an integral structure.

[0022] Furthermore, the top of each inclined ejector connector 4 is slidably connected to the inclined ejector rod 5 through the opened guide hole 16. A spring opening 13 is opened at one end of each of the two inclined ejector connectors 4, and a spring part 14 is installed inside each of the two spring openings 13. The spring part 14 is connected to the non-molding cavity part of the head cover injection mold 1 to produce a resisting effect. After the inclined ejector is demolded, the spring part 14 is compressed and stores energy. After demolding is completed, the restraining force disappears, and the stored energy is released so that the inclined ejector connector 4 can return to the initial state, which facilitates subsequent injection molding operations.

[0023] Furthermore, in order to limit each inclined ejector rod 5 when the mold is closed, a limiting recess 12 is provided on the side of each inclined ejector rod 5, and the limiting recess 12 limits the head cover injection mold 1.

[0024] like Figure 2 As shown in Embodiment 2: Based on Embodiment 1, the same structure will not be described again. A molding contact seat 9 is installed on the side of each molding connecting block 3, and an undercut molding contour surface 10 is provided on one side of the molding contact seat 9. The undercut molding contour surface 10 is connected with the undercut part of the electric vehicle head cover injection molded part, which facilitates good mold opening accuracy during the inclined top mold opening process.

[0025] Example 3: The small inclined ejector demolding mechanism includes a head cover injection mold 1 and an electric vehicle head cover injection molded part 2. The electric vehicle head cover injection molded part 2 is formed in the molding cavity of the head cover injection mold 1. A sliding opening 8 is provided in the middle of both sides of the head cover injection mold 1. Two molding connecting blocks 3 are provided inside the sliding opening 8. An inclined ejector connecting seat 4 is installed at the bottom of each of the two molding connecting blocks 3. The bottom of each molding connecting block 3 is connected to the inclined ejector connecting seat 4 by bolts. This ensures that the connection between the molding connecting block 3 and the inclined ejector connecting seat 4 has good stability, and the two become an integral structure.

[0026] In order to better position the inclined top connecting seat 4 within the sliding range of the sliding opening 8 and prevent the inclined top connecting seat 4 from separating from the sliding opening 8, a stepped part 15 is installed on both sides of the top of the inclined top connecting seat 4. An inclined top seat limiting strip 11 is installed on the upper end of the two stepped parts 15. The inclined top seat limiting strip 11 is connected to the head cover injection mold 1.

[0027] Furthermore, in order to determine the initial position of the inclined ejector connector 4 in the sliding opening 8, inclined ejector limit blocks 6 corresponding to the sliding opening 8 are set on both sides of the head cover injection mold 1, and the inclined ejector connector 4 and the inclined ejector limit blocks 6 make limit contact.

[0028] In Embodiments 1 to 3, in order to ensure that the headgear injection mold 1 has power for mold opening and demolding, a telescopic cylinder part 7 can be installed at the bottom template of the headgear injection mold 1. The telescopic cylinder part 7 includes, but is not limited to, air cylinders, hydraulic cylinders and electric cylinders, as long as they can make telescopic movements.
