[0001] This utility model belongs to the technical field of electric vehicle parts and components, and relates to a multi-cavity injection molding mold for electric vehicle plastic parts. Background Technology

[0002] Plastic parts are an important component of electric vehicles. Currently, these plastic parts are mainly processed using injection molds. The processing of plastic parts for electric vehicles requires specific injection molds for each individual plastic part.

[0003] Traditional injection molds cannot process multiple electric vehicle plastic parts simultaneously with a single mold. Each plastic part needs to be processed individually, which not only affects the processing efficiency of electric vehicle plastic parts but also increases the production cost. Summary of the Invention

[0004] The purpose of this invention is to provide a multi-cavity injection mold for plastic parts of electric vehicles, 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 multi-cavity injection molding mold for electric vehicle plastic parts, comprising a lower mounting plate and an upper mounting plate. A lower mold base is fixedly installed at the top of the lower mounting plate, and an upper mold base adapted to the lower mold base is fixedly installed at the bottom of the upper mounting plate. A seat inner cover mold cavity is opened on one side of the top of the lower mold base, and a pedal mold cavity is opened on the other side of the top of the lower mold base. A foot pedal cover mold cavity is opened on both sides of the top of the lower mold base. A cross-shaped flow channel is opened at the center of the lower mold base, and the cross-shaped flow channel is connected to the seat inner cover mold cavity, the pedal mold cavity, and the foot pedal cover mold cavity, respectively.

[0006] In the above-mentioned multi-cavity injection molding mold for electric vehicle plastic parts, a glue inlet is fixedly provided at the center of the upper mounting plate, and a glue inlet channel is opened inside the upper mold base. The top end of the glue inlet channel is connected to the glue inlet, and the bottom end of the glue inlet channel is aligned with the center of the cross-shaped channel.

[0007] In the above-mentioned multi-cavity injection molding mold for electric vehicle plastic parts, limit guide holes are provided at the four corners of the bottom of the upper mold base, and limit guide posts adapted to the limit guide holes are fixed at the four corners of the top of the lower mold base. The four limit guide posts are inserted into the corresponding limit guide holes.

[0017] 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.

[0018] like Figure 1-4 As shown, the present invention relates to a multi-cavity injection molding mold for electric vehicle plastic parts, comprising a lower mounting plate 1 and an upper mounting plate 5. A lower mold base 4 is fixedly mounted on the top of the lower mounting plate 1, and an upper mold base 6 adapted to the lower mold base 4 is fixedly mounted on the bottom of the upper mounting plate 5. A seat inner cover mold cavity 12 is opened on one side of the top of the lower mold base 4, and a pedal mold cavity 14 is opened on the other side of the top of the lower mold base 4. A foot pedal cover mold cavity 13 is symmetrically arranged on both sides of the top of the lower mold base 4. A cross-shaped flow channel 15 is opened at the center of the lower mold base 4, and the cross-shaped flow channel 15 is connected to the seat inner cover mold cavity 12, the pedal mold cavity 14, and the foot pedal cover mold cavity 13 respectively.

[0019] Specifically, the injection mold has a seat inner cover cavity 12, a pedal cavity 14, and a foot pedal cover cavity 13 respectively opened inside the lower mold base 4, and the multiple cavities are connected by a cross-shaped runner 15. During injection molding, the seat inner cover, pedal, and foot pedal cover can be injected synchronously and integrally, without the need to open different injection molds for different parts. This not only improves the processing efficiency of plastic parts for electric vehicles, but also saves production costs.

[0020] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the present invention relates to a multi-cavity injection molding mold for electric vehicle plastic parts. A glue inlet 10 is fixedly provided at the center of the upper mounting plate 5. A glue inlet channel 17 is provided inside the upper mold base 6. The top end of the glue inlet channel 17 is connected to the glue inlet 10, and the bottom end of the glue inlet channel 17 is aligned with the center of the cross-shaped channel 15.

[0021] Specifically, by flowing the molten adhesive in the injection channel 17 into the cross-shaped channel 15, it can flow into the corresponding mold cavity through the cross-shaped channel 15.

[0022] Limiting guide holes 16 are provided at the four corners of the bottom of the upper mold base 6, and limiting guide posts 11 adapted to the limiting guide holes 16 are fixed at the four corners of the top of the lower mold base 4. The four limiting guide posts 11 are inserted into the corresponding limiting guide holes 16.

[0023] Specifically, the cooperation of the limiting guide post 11 and the limiting guide hole 16 improves the mold closing accuracy of the upper mold base 6 and the lower mold base 4.

[0024] A convex locking module 8 is fixedly installed at the center of each of the four sides at the bottom of the upper mold base 6, and a concave locking module 7 is fixedly installed at the center of each of the four sides at the top of the lower mold base 4. The convex locking module 8 is plugged into the corresponding concave locking module 7.

[0025] Specifically, by inserting the convex locking module 8 and the concave locking module 7, the mold closing accuracy between the upper mold base 6 and the lower mold base 4 is effectively ensured after the mold is closed.

[0026] Multiple cooling water inlets 9 are provided at equal intervals on both sides of the upper mold base 6 and the lower mold base 4. The multiple cooling water inlets 9 are connected to an external water pump through cooling water pipes.

[0027] Specifically, by connecting to an external water pump through the cooling water inlet 9, the internal plastic parts can be rapidly cooled and molded during the injection molding process.

[0028] A movable connecting plate 2 is provided at the center of the lower mounting plate 1. Multiple push rods 3 are fixedly provided at equal intervals at the top of the connecting plate 2. The multiple push rods 3 are respectively connected to the interior of the inner cover mold cavity 12, the foot pedal mold cavity 14 and the foot cover mold cavity 13. The bottom center of the lower mounting plate 1 is fixedly connected to the telescopic cylinder of the injection molding machine.

[0029] Specifically, by extending and retracting the ejector rod 3, the molded plastic part inside the mold cavity can be pushed out, thus enabling the molded plastic part to be demolded.

[0030] In specific implementation, when using this multi-cavity injection molding mold for electric vehicle plastic parts, the injection mold is first installed in the injection molding machine. During injection, the injection pipe of the injection molding machine is inserted into the injection nozzle 10. The molten plastic flows through the injection channel 17 into the cross-shaped channel 15, and then flows through the cross-shaped channel 15 into the seat inner cover cavity 12, the pedal cavity 14, and the footrest cover cavity 13 respectively for injection molding. At the same time, an external water pump flows cooling water from the cooling water port 9 into the cooling channels inside the lower mold base 4 and the upper mold base 6 to achieve water-cooled molding. After the upper mold base 6 separates from the lower mold base 4, the molded seat inner cover, pedal, and footrest cover are demolded by the ejector pin, realizing the simultaneous injection molding of the seat inner cover, pedal, and footrest cover in one go, replacing the traditional method that requires a single injection mold for injection molding. This not only improves the processing efficiency of electric vehicle plastic parts but also saves production costs.
