Description

Technical Field

[0001] This utility model relates to the field of automotive injection molds, and in particular to a multifunctional injection mold for automotive parts. Background Technology

[0002] Automotive parts are an indispensable component of the overall function of a car. Each part performs a specific function and together they ensure the safe operation of the car. Automotive part injection molds are injection tools designed specifically for the production of automotive parts. Through the injection molding process, parts that meet the requirements can be produced quickly, satisfying the automotive industry's demand for high-quality and high-efficiency production.

[0003] Traditionally, multi-functional injection molds used for some automotive parts often encounter difficulties in removing the material after the plastic slurry is injected and molded due to strong adhesion between the slurry and the mold core. This problem seriously hinders subsequent processing and reduces overall production efficiency. Therefore, a new solution is needed to address this issue.

[0004] Therefore, those skilled in the art provide a multifunctional injection mold for automotive parts to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a multi-functional injection mold for automotive parts. Compared to traditional multi-functional injection molds for automotive parts, this invention features an ejector mechanism. After the molded product cools inside the mold core, it is ejected by ejector pins. The ejected product falls onto a conveyor belt for further processing. Simultaneously, gears with varying numbers of racks are incorporated. When the upper mold plate moves, it drives the first rack, which in turn drives the second rack. The second rack's movement is slowed down by the second gear, thus slowing down the ejector pin's movement. This allows for sufficient distance between the front and rear mold cores for the ejector pins to operate.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A multifunctional injection mold for automotive parts includes a base and an ejector mechanism. An upper mold mechanism is provided on one side of the upper surface of the base. The upper mold mechanism includes a base plate, and a plurality of hydraulic rods are fixedly connected to the inner wall of the base plate. An upper template is fixedly connected to the output end of the hydraulic rods. A first mold core groove is formed in the middle of the outer wall of the rear end of the upper template. A front mold core is fixedly connected to the inner wall of the first mold core groove. A lower mold mechanism is provided on the side of the upper surface of the base away from the upper mold mechanism. The lower mold mechanism includes a base plate, and a lower template is fixedly connected to the middle of the outer wall of the front end of the base plate. A second mold core groove is formed in the middle of the outer wall of the front end of the lower template. A rear mold core is fixedly connected to the inner wall of the second mold core groove.

[0008] The ejector mechanism includes a first gear and a second gear meshing with the first gear. A support plate is fixedly connected to the lower end of the outer wall of the front end of the base plate. An ejector pin base plate is provided in the middle of the upper surface of the support plate. Multiple ejector pins are fixedly connected to the outer wall of the front end of the ejector pin base plate. The first gear is rotatably connected to both ends of the upper surface of the support plate. The first gear meshes with the second gear. A first rack is fixedly connected to both inner walls of the upper template. A second rack is fixedly connected to both outer walls of the ejector pin base plate.

[0009] Through the above technical solution, the automotive part uses a multi-functional injection mold with an ejector mechanism. After the injection slurry cools in the mold core, the upper mold plate moves backward, driving the gear to rotate. This, in turn, drives the ejector pin to move forward through the meshing rack, thus facilitating the ejection of the material.

[0010] Furthermore, the first base plate is fixedly connected to one side of the upper surface of the base, and the second base plate is fixedly connected to the side of the upper surface of the base away from the first base plate;

[0011] The above technical solution allows for the installation of a base plate, which facilitates the fixing and support of the template for injection molding operations.

[0012] Furthermore, multiple telescopic rods are fixedly connected to the outer walls of the front and rear ends of the upper template, and the ends of the telescopic rods away from the upper template are fixedly connected to the first base plate and the second base plate, respectively.

[0013] Through the above technical solution, the telescopic rod supports the upper template and facilitates the limiting and alignment of the upper template movement, making the injection molding operation of the mold more precise.

[0014] Furthermore, springs are fitted onto the outer wall of each telescopic rod;

[0015] The above technical solution uses a spring to help the telescopic rod remain stable during movement and to provide cushioning for vibrations, ensuring the stability of the upper mold plate and thus guaranteeing the quality of injection molding.

[0016] Furthermore, both the first gear and the second gear are rotatably connected to both sides of the upper surface of the support plate;

[0017] With the above technical solution, the second gear has more teeth than the first gear, which makes it easier to slow down the rotation speed of the second gear, thereby slowing down the movement speed of the second rack and the ejector plate, so as to leave enough space when the upper template retracts, and facilitate the ejector to perform the ejection operation.

[0018] Furthermore, the first gear is meshed with the first rack, and the second gear is meshed with the second rack;

[0019] The above technical solution facilitates the first rack to drive the second rack through the meshing of gears, thereby driving the ejector base plate and ejector pin to move.

[0020] Furthermore, a slide rail is fixedly connected to the middle of the upper surface of the support plate, and a slide groove is provided on the lower surface of the ejector pin base plate;

[0021] The above technical solution provides support and limits the ejector base plate by setting up the slide groove and slide rail, which facilitates more stable operation of the ejector base plate.

[0022] Furthermore, a conveyor belt is fixedly connected to the middle of the upper surface of the base;

[0023] With the above technical solution, the ejector pin pushes the injection molded product out and it falls onto the conveyor belt, making it easier to carry out the next step of the operation.

[0024] This utility model has the following beneficial effects:

[0025] 1. The present invention proposes a multi-functional injection mold for automotive parts. Compared with most existing multi-functional injection molds for automotive parts, this multi-functional injection mold for automotive parts is equipped with an ejector mechanism. During injection, the position of the ejector pin is flush with the rear mold core, which facilitates the injection operation. After the injection molded product cools in the mold core, the mold is ejected by the ejector pin, which avoids the injection molded product sticking to the mold core and causing difficulties in material removal. The ejected injection molded product will fall onto the conveyor belt, which is convenient for the next step of operation.

[0026] 2. The present invention proposes a multi-functional injection mold for automotive parts. Compared with most existing multi-functional injection molds for automotive parts, this multi-functional injection mold for automotive parts uses gears with varying numbers of racks. When the upper mold plate moves, it drives the first rack to move. When the gear drives the second rack to move, the second gear slows down the movement speed of the second rack, thereby slowing down the movement speed of the ejector pin. This allows for sufficient movement between the front and rear mold cores to facilitate the ejector pin's operation. Attached Figure Description

[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0038] One embodiment of this utility model is provided:

[0039] Reference Figure 1A multifunctional injection mold for automotive parts includes a base 1 and an ejector mechanism 5. An upper mold mechanism 3 is provided on one side of the upper surface of the base 1. The upper mold mechanism 3 includes a base plate 301. Multiple hydraulic rods 305 are fixedly connected to the inner wall of the base plate 301. An upper template 302 is fixedly connected to the output end of the hydraulic rods 305. A first mold core groove 303 is opened in the middle of the outer wall of the rear end of the upper template 302. A front mold core 304 is fixedly connected to the inner wall of the first mold core groove 303. A lower mold mechanism 4 is provided on the side of the upper surface of the base 1 away from the upper mold mechanism 3. The lower mold mechanism 4 includes a base plate 401. A lower template 402 is fixedly connected to the middle of the outer wall of the front end of the base plate 401. A second mold core groove 403 is opened in the middle of the outer wall of the front end of the lower template 402. A rear mold core 404 is fixedly connected to the inner wall of the second mold core groove 403.

[0040] The feeding mechanism 5 includes a first gear 503 and a second gear 504 meshing with the first gear 503. A support plate 509 is fixedly connected to the lower end of the outer wall of the front end of the base plate 401. A pin base plate 505 is provided in the middle of the upper surface of the support plate 509. Multiple pins 506 are fixedly connected to the outer wall of the front end of the pin base plate 505. The first gear 503 is rotatably connected to both ends of the upper surface of the support plate 509. The first gear 503 meshes with the second gear 504. The inner walls of both sides of the upper template 302 are fixedly connected to the first rack 501. The outer walls of both sides of the pin base plate 505 are fixedly connected to the second rack 502.

[0041] The automotive part uses a multi-functional injection mold with an ejector mechanism 5. After the injection slurry cools in the mold core, the upper mold plate 302 moves backward, driving the gear to rotate. This, in turn, drives the ejector pin 506 to move forward through the meshing rack, thus facilitating the ejection of the material.

[0042] Reference Figure 1 , Figure 2 and Figure 3 The base plate 301 is fixedly connected to one side of the upper surface of the base 1, and the base plate 401 is fixedly connected to the side of the upper surface of the base 1 away from the base plate 301. The base plates facilitate the fixing and support of the template for injection molding. Multiple telescopic rods 306 are fixedly connected to the outer walls of the front and rear ends of the upper template 302. The ends of the telescopic rods 306 away from the upper template 302 are fixedly connected to the base plate 301 and the base plate 401 respectively. The telescopic rods 306 support the upper template 302 and facilitate the limiting and alignment of the movement of the upper template 302, making the injection molding operation of the mold more precise. The outer walls of the telescopic rods 306 are fitted with springs 307. The springs 307 help the telescopic rods 306 maintain stability during movement and provide cushioning for vibration, ensuring the stability of the upper template 302 and thus ensuring the quality of injection molding.

[0043] Reference Figure 1 , Figure 4 and Figure 5 Both the first gear 503 and the second gear 504 are rotatably connected to both sides of the upper surface of the support plate 509. The second gear 504 has more teeth than the first gear 503, which helps to slow down the rotational speed of the second gear 504, thereby slowing down the moving speed of the second rack 502 and the ejector base plate 505. This allows sufficient space to be left when the upper template 302 retracts, facilitating the ejector pin 506 to perform the ejection operation. The first gear 503 is meshed with the first rack 501, and the second gear 504 is meshed with the second rack 502, facilitating the first rack 501 to pass through the teeth. The meshing between the wheels drives the second rack 502, thereby moving the ejector base plate 505 and the ejector pin 506. A slide rail 508 is fixedly connected to the middle of the upper surface of the support plate 509. A groove 507 is provided on the lower surface of the ejector base plate 505. The groove 507 and the slide rail 508 provide support and limit the movement of the ejector base plate 505, making the ejector base plate 505 run more stably. A conveyor belt 2 is fixedly connected to the middle of the upper surface of the base 1. After the ejector pin 506 ejects the injection molded product, it falls onto the conveyor belt 2, which facilitates the next step of the operation.

[0044] Working principle: When in use, the hydraulic rod 305 is activated, which moves the upper mold plate 302, causing the front mold core 304 and the rear mold core 404 to fit together. Molten plastic slurry is injected through the external injection tube. After the plastic slurry cools, the hydraulic rod 305 is activated again to retract the upper mold plate 302. The movement of the upper mold plate 302 moves the first rack 501, which in turn rotates the first gear 503. The rotation of the first gear 503 drives the meshing second gear 504 to rotate, thereby moving the second rack 502 and the ejector base plate 505. This, in turn, moves the ejector pin 506 forward. The second gear 504 has more teeth than the first gear 503, so the movement speed of the ejector base plate 505 and the ejector pin 506 is slower. This allows sufficient distance to be maintained between the front mold core 304 and the rear mold core 404, facilitating the ejector pin 506 to eject the material, which then falls onto the conveyor belt 2 for further processing.

[0045] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
