[0017] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0018] Embodiment 1

[0019] As Figures 1-4 shown, the present utility model provides a technical solution: a child bike handle injection mold, which includes a lower template 1 and an upper template 2. An injection port 3 is provided on the upper surface of the upper template 2, and a bike handle cavity 4 is provided in both the lower template 1 and the upper template 2. The injection port 3 communicates with the bike handle cavity 4 in the upper template 2. The injection material is extruded through the injection port 3 and sent to the bike handle cavity 4 in the lower template 1 and the upper template 2, and the injection molding of the child bike handle is completed at the bike handle cavity 4. Sliding grooves 5 are provided on the left and right sides and the rear side of the injection port 3 in the lower template 1 and the upper template 2. The setting of the sliding grooves 5 facilitates the sliding movement operations of the sliders 6, connecting plates 7, cleaning scrapers 8 and closing plates 9 in the lower template 1 and the upper template 2. And sliders 6 are slidably connected in the sliding grooves 5 at their left and right side positions. One end of the slider 6 is fixed with a connecting plate 7, and the connecting plate 7 is slidably connected in the sliding groove 5. The connecting plate 7 serves to connect the slider 6, the cleaning scraper 8 and the closing plate 9 into one body, facilitating their simultaneous movement. The front and rear ends of the connecting plate 7 are respectively fixedly connected with a cleaning scraper 8 and a closing plate 9. The cleaning scraper 8 scrapes the residual material on the surface of the bike handle cavity 4 when moving, and the closing plate 9 serves to close one end of the bike handle cavity 4. A lead screw 11 is rotatably connected and a track rod 12 is fixedly connected at the left and right side positions of the sliding groove 5. The track rod 12 further improves the linear movement stability of the overall slider 6, connecting plate 7, cleaning scraper 8 and closing plate 9. One of the sliders 6 in the lower template 1 and the upper template 2 is threadedly connected to the lead screw 11 and the other is connected through the track rod 12. A handle 13 is rotatably connected to the outer surface of one side of the lower template 1, and one end of the handle 13 passes through the lower template 1 and is fixedly connected to the lead screw 11. By rotating the handle 13 to drive the lead screw 11 to rotate, the slider 6, the connecting plate 7, the cleaning scraper 8 and the closing plate 9 carry the injection-molded child bike handle and move to one side of the lower template 1 and the upper template 2. During the movement of the cleaning scraper 8, the residual material on the surface of the bike handle cavity 4 will be scraped off. When the child bike handle moves to the outside of the lower template 1 and the upper template 2, the cleaning scraper 8 will also scrape the residual material on the bike handle cavity 4 out to the outside, realizing the cleaning work.

[0020] Embodiment 2

[0021] As Figures 1-4As shown in the figure, a clamping block 10 is fixedly connected to the upper end surface of the closing plate 9, and the clamping block 10 is engaged with the upper template 2. The clamping block 10 is slidably connected to the upper template 2. Through the engagement of the clamping block 10 with the upper template 2, the closing stability of the closing plate 9 at one end of the handle cavity 4 of the vehicle is improved. A support plate 14 is fixedly connected to one side surface of the lower template 1. When the connecting plate 7, the cleaning scraper 8 and the closing plate 9 move to the outside of the lower template 1 and the upper template 2, the support plate 14 plays a role in supporting the connecting plate 7. The cross-sectional areas of the handle cavity 4, the cleaning scraper 8 and the closing plate 9 are the same, and the cross-sectional areas of the cleaning scraper 8 and the closing plate 9 are adapted to the cross-sectional area at the middle of the chute 5. In this way, while the cleaning scraper 8 can smoothly scrape the residual materials on the surface of the handle cavity 4 of the vehicle, the cleaning scraper 8 and the closing plate 9 can easily slide at the handle cavity 4 and the chute 5.

[0022] Working principle:

[0023] As Figures 1-4 shown in the figure, when the present utility model is in use, the injection molding raw material is injected into the handle cavity 4 of the lower template 1 and the upper template 2 through the injection port 3, and the children's bicycle handle is injection molded at the handle cavity 4. When the children's bicycle handle needs to be taken out after the injection molding is completed, the user first manually swings and rotates the handle 13. The rotation of the handle 13 drives the rotation of the lead screw 11. The rotation of the lead screw 11 drives the slider 6, the connecting plate 7, the cleaning scraper 8 and the closing plate 9 to move along the chute 5 and the track rod 12 towards the outside of the lower template 1 and the upper template 2. At this time, the clamping block 10 gradually disengages from the connection with the upper template 2, and the cleaning scraper 8 and the closing plate 9 will carry the already injection molded children's bicycle handle between them during the movement. During the movement of the cleaning scraper 8, the residual materials on the surface of the handle cavity 4 will also be scraped off. When the children's bicycle handle between the cleaning scraper 8 and the closing plate 9 moves to the outside of the lower template 1 and the upper template 2, the support plate 14 will support the connecting plate 7, facilitating the user to stably remove the children's bicycle handle from above. At this time, the cleaning scraper 8 also scrapes the residual materials on the handle cavity 4 to the outside, realizing the cleaning work.

[0024] The above is only a preferred embodiment of the present utility model, and it is not a limitation to the present utility model in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present utility model, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present utility model still belong to the protection scope of the technical solution of the present utility model.
