Electric vehicle taillight inner lamp cover mold stacked core insert sequential demolding mechanism

Abstract

This utility model provides a sequential demolding mechanism for the stacked core inserts of an electric vehicle taillight inner lamp cover mold, including a lower ejector plate, an upper ejector plate, and a lower injection mold. The upper ejector plate is stacked on top of the lower ejector plate. The upper injection mold has an assembly groove at its top, and a lower mold core is fixedly installed inside the assembly groove. Through holes are formed on both sides of the top of the lower mold core, and a separator sleeve is nested inside each of the two through holes. The inner lamp cover core is housed inside the separator sleeve and is fixedly connected to the bottom of the assembly groove. In this utility model, the mold core of the taillight inner lamp cover mold is divided into an outer lamp cover core and an inner lamp cover core by the separator sleeve. During demolding, the center of the inner lamp cover is first separated by the internal ejector pins, and then the periphery of the inner lamp cover is demolded by the external ejector pins, achieving sequential demolding. This effectively ensures the surface integrity of the inner lamp cover and improves its quality.

Description

Technical Field

[0001] This utility model belongs to the field of electric vehicle parts processing technology, and relates to a sequential demolding mechanism for the stacked core insert of the taillight inner lamp cover mold of an electric vehicle. Background Technology

[0002] The inner lamp cover of an electric vehicle taillight is an important component of the electric vehicle's headlight. The inner lamp cover of an electric vehicle taillight is generally made of plastic and is mainly injection molded during the production and processing.

[0003] To increase the illumination area, existing electric vehicle taillights generally adopt a layered design. During demolding, the part embedded in the center during simultaneous demolding is prone to deformation, which affects the surface integrity of the inner lamp cover of the electric vehicle taillight. To address this issue, we designed a sequential demolding mechanism for the layered core insert of the inner lamp cover mold of the electric vehicle taillight. Summary of the Invention

The upper ejector plate is stacked on top of the lower ejector plate. An assembly groove is formed at the top of the injection mold lower mold. A lower mold core is fixedly installed inside the assembly groove. Through holes are formed on both sides of the top of the lower mold core. A partition sleeve is nested inside each of the two through holes. An inner lamp cover core is set inside the partition sleeve. The inner lamp cover core is fixedly connected to the bottom of the assembly groove. Multiple internal ejector pins are inserted at equal intervals inside the inner lamp cover core. The internal ejector pins are fixedly connected to the top of the upper ejector plate. An outer lamp cover core is set outside the partition sleeve. Multiple external ejector pins are inserted at equal intervals inside the outer lamp cover core. The external ejector pins pass through the upper ejector plate and are fixedly connected to the top of the lower ejector plate.

[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 1-5 As shown, the present invention relates to a sequential demolding mechanism for the stacked core inserts of an electric vehicle taillight inner lamp cover mold, comprising a lower ejector plate 1, an upper ejector plate 2, and an injection mold 3. The upper ejector plate 2 is stacked on top of the lower ejector plate 1. An assembly groove 6 is provided at the top of the injection mold 3. A lower mold core 7 is fixedly installed inside the assembly groove 6. Through holes are provided on both sides of the top of the lower mold core 7. A partition sleeve 9 is nested inside each of the two through holes. An inner lamp cover core 11 is provided inside the partition sleeve 9. The inner lamp cover core 11 is fixedly connected to the bottom of the assembly groove 6. Multiple internal ejector pins 14 are equidistantly inserted inside the inner lamp cover core 11. The internal ejector pins 14 are fixedly connected to the top of the upper ejector plate 2. An outer lamp cover core 10 is provided outside the partition sleeve 9. Multiple outer ejector pins 15 are equidistantly inserted inside the outer lamp cover core 10. The outer ejector pins 15 pass through the upper ejector plate 2 and are fixedly connected to the top of the lower ejector plate 1.

[0020] Specifically, the mold core of the rear taillight inner lamp cover mold is divided into an outer lamp cover core 10 and an inner lamp cover core 11 by a separating sleeve 9. During demolding, the center of the inner lamp cover is first separated by the internal ejector pin 14, and then the periphery of the inner lamp cover is demolded by the external ejector pin 15, so as to achieve sequential demolding, effectively ensuring the surface integrity of the inner lamp cover and improving the quality of the inner lamp cover.

[0021] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the electric vehicle taillight inner lamp cover mold stacked core insert sequential demolding mechanism of this utility model has mounting seats 8 fixedly provided at the four corners of the top of the lower mold core 7, and mounting screw holes are opened at the center of the four mounting seats 8. The mounting screw holes are fixedly connected to the assembly groove 6 by screws.

[0022] Specifically, the mounting base 8 allows the lower mold core 7 to be fixedly installed inside the assembly slot 6.

[0023] A fixing block 12 is fixedly provided at the center of the lower mold core 7, and an injection channel 13 communicating with the outer cores 10 of the two lampshades is provided in the middle of the fixing block 12.

[0024] Specifically, through the opening of the glue injection channel 13, the molten glue first flows into the outer core 10 of the lamp cover, and then flows from the outer core 10 of the lamp cover into the inner core 11 of the lamp cover.

[0025] Multiple cooling water pipes are fixedly installed inside the injection mold 3, and multiple cooling holes 4 are opened on both sides of the injection mold 3. The cooling holes 4 are connected to the ends of the cooling water pipes.

[0026] Specifically, the cooling hole 4 can be connected to an external cooling water pipe to achieve water circulation cooling inside the injection mold.

[0027] Limiting guide holes 5 are fixedly provided at the four corners of the top of the injection mold 3. The inner diameter of the limiting guide holes 5 is matched with the end size of the limiting guide posts provided at the four corners of the bottom of the injection mold.

[0028] Specifically, by opening the limiting guide hole 5 and adapting the limiting guide post, the accuracy of mold closing between the lower injection mold 3 and the upper injection mold is improved.

[0029] A limiting ring is fixedly provided at the bottom of the dividing sleeve 9, and the bottom of the limiting ring is in contact with the bottom of the lower mold core 7.

[0030] Specifically, by setting the bottom limiting retaining ring of the dividing sleeve 9, the dividing sleeve 9 can be fixed inside the through hole, thus preventing the dividing sleeve 9 from separating from the through hole.

[0031] In specific implementation, when using the sequential demolding mechanism of the stacked core insert of the taillight inner lamp cover mold of this electric vehicle, the upper ejector plate 2 is first pushed upward by the electric push rod of the injection molding machine. The upward movement of the upper ejector plate 2 drives the inner ejector pin 14 to move upward, which facilitates the separation of the center of the lamp cover from the center. Then, the lower ejector plate 1 is pushed upward by the electric push rod. The upward movement of the lower ejector plate 1 drives the outer ejector pin 15 to move upward. The outer ejector pin 15 demolds the periphery of the lamp cover, realizing the sequential demolding of the inner and outer parts of the lamp cover. This avoids deformation caused by the lamp cover being embedded inside the partition sleeve 9 during the direct demolding process of the stacked lamp cover, thereby improving the surface integrity of the demolding of the stacked inner lamp cover.
