Description

Technical Field

[0001] This utility model belongs to the field of motorcycle tail box processing technology, and relates to a motorcycle tail box bottom mold with multiple internal pulling and multiple inclined ejection demolding mechanisms. Background Technology

[0002] A motorcycle tail box is a component of a motorcycle. By attaching a motorcycle tail box to the rear of the motorcycle, it is convenient to store auxiliary riding items such as helmets and raincoats. During the manufacturing process, motorcycle tail boxes are mainly injection molded using injection molds.

[0003] In the traditional injection molding process for motorcycle tail box bottoms, we found that because the motorcycle tail box bottom has a rounded vessel-like structure, when demolding is done solely by ejector pins during injection molding, the sides of the motorcycle tail box tend to stick to the inside of the mold cavity after the top of the tail box has been demolded, affecting the quick and complete demolding of the motorcycle tail box. To address this issue, we designed a motorcycle tail box bottom mold with multiple internal pull-out and multiple inclined ejector demolding mechanisms. Summary of the Invention

[0004] The purpose of this invention is to provide a motorcycle tail box bottom mold with multiple internal pulling and multiple inclined ejection demolding mechanisms 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 motorcycle tail box bottom mold with multiple internal pulling and multiple inclined ejection mechanisms, comprising a lower base, a lower mounting plate, and an upper mounting plate. The lower mounting plate is fixedly mounted on the top of the lower base, and a lower mold base is fixedly mounted on the top of the lower mounting plate. An upper mold base that matches the lower mold base is fixedly mounted on the bottom of the upper mounting plate. Grooves are provided at the two corners and the center of the side of the top of the lower mold base. A convex insert is slidably connected inside the groove. An inclined hole is provided on the top of the convex insert. Inclined guide posts are fixedly mounted at the two corners and the center of the side of the bottom of the upper mold base. The inclined guide posts are inserted into the inclined holes.

[0006] In the motorcycle tail box bottom mold with multiple internal pull-out and multiple inclined ejector demolding mechanisms described above, strip-shaped limiting blocks are fixedly installed on both sides of the inner wall of the groove. The bottom ends of the two strip-shaped limiting blocks are in contact with the two sides of the top of the convex insert. The bottom of the groove is provided with a strip-shaped groove that is compatible with the inclined ejector rod.

[0007] In the motorcycle tail box bottom mold with multiple internal pulling and multiple inclined ejector demolding mechanisms described above, a mold cavity is fixedly provided on the top of the lower mold base, and multiple through holes are equally spaced on the top of the mold cavity, with inclined ejector rods inserted into the interior of each of the multiple through holes.

[0008] In the motorcycle tail box bottom mold with multiple internal pull-out and multiple inclined ejector demolding mechanisms described above, the top of the lower base is provided with a connecting plate that is fixedly connected to the electric hydraulic cylinder of the injection molding machine, and the top of the connecting plate is fixedly connected to the bottom of multiple inclined ejector rods.

[0009] In the motorcycle tail box bottom mold with multiple internal pulling and multiple inclined ejection demolding mechanisms described above, multiple through cooling water pipes are fixedly installed at equal intervals inside the lower mold base and the upper mold base, and multiple cooling water inlets are fixedly installed at equal intervals on the sides of the lower mold base and the upper mold base, and the multiple cooling water inlets are connected to the ends of the cooling water pipes.

[0010] In the motorcycle tail box bottom mold with multiple internal pull-out and multiple inclined ejection demolding mechanisms described above, limit guide pillars are fixedly installed at the four corners of the top of the lower mold base, and limit guide holes are opened at the four corners of the bottom of the upper mold base. The four limit guide pillars are inserted into the corresponding limit guide holes.

[0011] In the motorcycle tail box bottom mold with multiple internal pull-out and multiple inclined ejection demolding mechanisms described above, a glue injection nozzle is fixedly provided at the center of the upper mounting plate, and a glue injection channel is opened inside the upper mold base, with the glue injection nozzle communicating with the glue injection channel.

[0012] Compared with the prior art, the advantages of the motorcycle tail box bottom mold with multiple internal pull-out and multiple inclined ejector demolding mechanisms of this utility model are as follows: the injection mold cooperates with the inclined guide post and the movable convex insert. During the demolding process between the upper mold base and the lower mold base, the inclined guide post pushes the convex insert to separate from the surface of the formed tail box. At the same time, the inclined ejector rod set inside the mold cavity facilitates the separation of the formed tail box from the mold cavity, thereby improving the demolding efficiency of the formed tail box.

[0020] 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.

[0021] like Figure 1-6 As shown, the present invention relates to a motorcycle tail box bottom mold with a multi-inner-pulling and multi-sloping-top demolding mechanism, comprising a lower base 1, a lower mounting plate 2, and an upper mounting plate 3. The lower mounting plate 2 is fixedly mounted on the top of the lower base 1, and a lower mold base 4 is fixedly mounted on the top of the lower mounting plate 2. An upper mold base 5 adapted to the lower mold base 4 is fixedly mounted on the bottom of the upper mounting plate 3. Grooves 17 are provided at the two corners and the center of the side of the top of the lower mold base 4. A convex insert 14 is slidably connected inside the groove 17. A sloping hole 15 is provided on the top of the convex insert 14. Sloping guide posts 8 are fixedly mounted at the two corners and the center of the side of the bottom of the upper mold base 5. The sloping guide posts 8 are inserted into the sloping holes 15.

[0022] Specifically, the injection mold uses a slanted guide post 8 to cooperate with a movable convex insert 14. During the demolding process between the upper mold base 5 and the lower mold base 4, the slanted guide post 8 pushes the convex insert 14 to separate from the surface of the formed tail box, thereby achieving the demolding of the formed tail box.

[0023] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the present invention provides a motorcycle tail box bottom mold with a multi-inner-pulling and multi-sloping-top demolding mechanism. Both sides of the inner wall of the groove 17 are fixedly installed with strip-shaped limiting blocks 18. The bottom ends of the two strip-shaped limiting blocks 18 are in contact with the two sides of the top of the convex insert 14. The bottom of the groove 17 is provided with a strip-shaped groove 7 that is adapted to the sloping top rod 11.

[0024] Specifically, by setting the strip-shaped limiting block 18, the convex insert 14 can be limited in the direction of movement, so that the convex insert 14 can only move horizontally.

[0025] The top of the lower mold base 4 is fixedly provided with a mold cavity 12, and the top of the mold cavity 12 is provided with multiple through holes 13 at equal intervals, and each of the multiple through holes 13 is inserted with an inclined push rod 11.

[0026] The top of the lower base 1 is provided with a connecting plate 10 that is fixedly connected to the electric hydraulic cylinder of the injection molding machine. The top of the connecting plate 10 is fixedly connected to the bottom of multiple inclined push rods 11.

[0027] Specifically, with the cooperation of the inclined ejector rod 11, the formed motorcycle tail box is ejected from the inside, further improving the demolding efficiency.

[0028] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the present invention provides a motorcycle tail box bottom mold with multiple internal pulling and multiple inclined ejection demolding mechanisms. Multiple through cooling water pipes 19 are fixedly installed at equal intervals inside the lower mold base 4 and the upper mold base 5. Multiple cooling water inlets 9 are fixedly installed at equal intervals on the sides of the lower mold base 4 and the upper mold base 5. The multiple cooling water inlets 9 are connected to the ends of the cooling water pipes 19.

[0029] Specifically, by installing cooling water pipes 19 inside both the lower mold base 4 and the upper mold base 5, heat dissipation can be achieved simultaneously from the outer and inner surfaces of the motorcycle tail box, thus improving the molding efficiency of the motorcycle tail box.

[0030] Limiting guide posts 16 are fixedly installed at the four corners of the top of the lower mold base 4, and limiting guide holes are opened at the four corners of the bottom of the upper mold base 5. The four limiting guide posts 16 are inserted into the corresponding limiting guide holes.

[0031] Specifically, the cooperation between the limiting guide post 16 and the limiting guide hole improves the mold closing accuracy between the lower mold base 4 and the upper mold base 5.

[0032] A glue injection nozzle 6 is fixedly provided at the center of the upper mounting plate 3, and a glue injection channel is provided inside the upper mold base 5. The glue injection nozzle 6 is connected to the glue injection channel.

[0033] Specifically, the setting of the injection nozzle 6 ensures that the molten plastic flows into the mold cavity 12 through the injection channel.

[0034] In specific implementation, when using this injection mold to produce a motorcycle tail box, the injection mold is first assembled with the injection molding machine, and multiple external hoses are connected to the corresponding cooling water inlets 9 to complete the assembly between the injection mold and the injection molding machine. After the injection mold is closed and injection molding is completed, the upper mold base 5 and the lower mold base 4 separate. At this time, the inclined guide post 8 of the upper mold base 5 pushes the convex insert 14 to move outward. Through the outward movement of the convex insert 14, the convex insert 14 is separated from the formed motorcycle tail box. After the upper mold base 5 and the lower mold base 4 are completely separated, the electric hydraulic cylinder of the injection molding machine pushes the connecting plate 10 to move. Through the movement of the connecting plate 10, the inclined ejector rod 11 moves. Through the inclined ejector rod 11, the formed motorcycle tail box is pushed upward from the bottom, completing the separation between the motorcycle tail box and the mold cavity 12. By using two methods to assist in demolding, the demolding efficiency of the motorcycle tail box is effectively ensured, while ensuring that the motorcycle tail box is not easily deformed, thus improving product quality.
