Description

Technical Field

[0001] This utility model relates to the field of injection mold technology, and specifically discloses an injection molding mold that facilitates material handling. Background Technology

[0002] Molds are various molds and tools used in industrial production to obtain desired products through methods such as injection molding, blow molding, extrusion, die casting, forging, smelting, and stamping. In short, a mold is a tool used to create shaped objects. This tool is composed of various parts, and different molds are composed of different parts. It mainly achieves the processing of the shape of the object by changing the physical state of the material being molded. Injection molds are the most common type of mold. An injection mold is a tool for producing plastic products. It injects heated and molten material into the mold cavity under high pressure, and after cooling and solidification, the shaped product is obtained.

[0003] In existing injection molds, after the moving mold and the fixed mold are separated, the obtained plastic products still need to be removed manually. This is not only inconvenient, but also prone to hand injuries during the process, causing inconvenience to the workers. Therefore, an injection mold that is easy to remove materials is needed to solve this problem. Utility Model Content

[0020] Please see Figure 1-3 An injection molding mold for easy material handling includes a base 1. Four symmetrically distributed support rods 3 are fixedly connected to the upper end face of the base 1. A top plate 2 is fixedly connected to the upper end face of the four support rods 3. An electric push rod 7 is installed on the upper end face of the top plate 2. The output end of the electric push rod 7 extends to the bottom of the top plate 2 and is fixedly connected to a first sliding plate 4 that is slidably connected to the four support rods 3. An upper mold 5 is fixedly connected to the lower end face of the first sliding plate 4. A lower mold 6 is fixedly connected to the upper end face of the base 1. Two ear plates 8 are fixedly connected to the upper end face of the top plate 2. A first rotating shaft 9 is rotatably connected inside the two ear plates 8. A first gear 10 is fixedly connected to the outer wall of the first rotating shaft 9. A first spur rack 11 that matches the first gear 10 is fixedly connected to the upper end face of the first sliding plate 4. A first synchronous pulley 12 is fixedly connected to the left end face of the first rotating shaft 9.

[0021] A second rotating shaft 13 is rotatably connected between the left and right end faces inside the base 1. The left end of the second rotating shaft 13 extends to the outside of the base 1 and is fixedly connected to a second synchronous pulley 14. The first synchronous pulley 12 and the second synchronous pulley 14 are connected by a synchronous belt drive. A second gear 15 is fixedly connected to the outer wall of the second rotating shaft 13. A second sliding plate 17 is provided inside the base 1. Two push rods 18 extending into the lower mold 6 are fixedly connected to the upper end face of the second sliding plate 17. A second spur rack 19 that meshes with the second gear 15 is fixedly connected to the lower end face of the second sliding plate 17.

[0022] In this embodiment: The electric actuator 7 is activated, causing the first sliding plate 4 to move downwards along the support rod 3, which in turn causes the upper mold 5 to move downwards and cooperate with the lower mold 6 for injection molding. After injection molding, the electric actuator 7 drives the first sliding plate 4 upwards, which in turn causes the upper mold 5 to move upwards and separate from the lower mold 6. Simultaneously, the first sliding plate 4 drives the first straight rack 11 upwards. When the first straight rack 11 meshes with the first gear 10, the continued upward movement of the first straight rack 11 drives the first gear 10 to rotate counterclockwise, which in turn drives the first rotating shaft 9 to... The first synchronous pulley 12 rotates counterclockwise, and the first synchronous pulley 12 further drives the second synchronous pulley 14 to rotate counterclockwise through the synchronous belt. In turn, the second shaft 13 drives the second gear 15 to rotate counterclockwise. The second gear 15 further drives the second slide plate 17 to move upward along the slide rod 16 through the second spur rack 19. In turn, it drives the ejector rod 18 to move upward, thus ejecting the product formed in the lower mold 6. In this invention, after the product is formed, when the upper mold 5 and the lower mold 6 are separated, the ejector rod 18 can be driven to move upward simultaneously to eject the product, making material discharge convenient.

[0023] As a technical optimization of this utility model, four symmetrically distributed slide rods 16 are fixedly connected between the upper and lower end faces inside the base 1, and the second slide plate 17 is slidably connected to the four slide rods 16.

[0024] In this embodiment, the slide bar 16 facilitates the limiting of the second slide plate 17, making the up-and-down movement of the second slide plate 17 stable.

[0025] As a technical optimization of this utility model, a limiting block is fixedly connected to the upper end face of the push rod 18, and a limiting groove matching the limiting block is opened on the bottom end face inside the lower mold 6.

[0026] In this embodiment, the limiting block and limiting groove facilitate the limiting of the ejector rod 18, preventing the ejector rod 18 from falling out of the lower mold 6.

[0027] As a technical optimization of this utility model, a through hole 22 is provided on the upper end surface of the top plate 2.

[0028] In this embodiment: by opening a through hole 22 on the upper end face of the top plate 2, the first straight rack 11 can pass through the through hole 22 and mesh with the first gear 10.

[0029] As a technical optimization of this utility model, the upper end surface of the first slide plate 4 is provided with an injection port 21.

[0030] In this embodiment, an injection port 21 is provided on the upper end surface of the first slide plate 4 to facilitate injection molding.

[0031] As a technical optimization of this utility model, a controller 20 is provided on the front end face of the base 1, and the electric push rod 7 is electrically connected to the controller 20.

[0032] In this embodiment, the controller 20 facilitates the normal operation of the electric actuator 7.

[0033] The working principle and usage process of this utility model are as follows: During use, the electric actuator 7 is activated, causing the first sliding plate 4 to move downwards along the support rod 3. This, in turn, causes the upper mold 5 to move downwards and cooperate with the lower mold 6 for injection molding. After injection molding is completed, the electric actuator 7 drives the first sliding plate 4 upwards, thereby causing the upper mold 5 to move upwards and separate from the lower mold 6. Simultaneously, the first sliding plate 4 drives the first straight rack 11 upwards. When the first straight rack 11 meshes with the first gear 10, its continued upward movement drives the first gear 10 to rotate counterclockwise, thus... The first synchronous pulley 12 is driven to rotate counterclockwise by the first rotating shaft 9. The first synchronous pulley 12 further drives the second synchronous pulley 14 to rotate counterclockwise via the synchronous belt. In turn, the second gear 15 is driven to rotate counterclockwise via the second rotating shaft 13. The second gear 15 further drives the second slide plate 17 to move upward along the slide rod 16 via the second spur rack 19. This drives the ejector rod 18 to move upward, thus ejecting the product formed in the lower mold 6. In this invention, after the product is formed, the ejector rod 18 can be driven to move upward simultaneously to eject the product when the upper mold 5 and the lower mold 6 are separated, making material discharge convenient.

[0034] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
