Description

Technical Field

[0001] The utility model relates to the field of automobile fender injection molding equipment, in particular to an injection molding machine for automobile fender production. Background Art

[0002] The injection molding machine used in the production of automobile fenders is a molding device designed specifically for the manufacture of this automobile part. Its working principle is similar to that of a syringe. Through the thrust of a screw or plunger, the molten plastic is accurately injected into a closed mold cavity, and the product is formed after cooling and solidification. In the production process of automobile fenders, the injection molding machine plays a key role with its high precision, high efficiency and high stability, ensuring that the molten plastic can be accurately injected into the mold and finally cooled and formed into a fender with precise shape and size.

[0003] However, during the actual production process, we encountered a problem: since the corners of the car fenders are designed to be corner-shaped, when the material is cut, these corners often come into direct contact with the collection box, resulting in partial damage to the fender corners. This problem not only affects the overall quality and appearance of the product, but also may increase production costs due to defective products and repair work.

[0004] We conducted an in-depth analysis of this issue. First, the corner design of the car fender makes it easy for it to collide or rub against the edge of the collection box during the unloading process. Especially when unloading at high speed, this contact is more direct and intense, increasing the risk of damage to the fender corner. In addition, the design defects and material selection of the collection box may also have an impact on the problem. If the edge of the collection box is too sharp or too hard, then the contact with the fender corner is more likely to cause damage. Utility Model Content

[0005] The main purpose of the utility model is to provide an injection molding machine for producing automobile fenders, which can effectively solve the problems raised in the background technology.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] An injection molding machine for producing automobile fenders comprises a machine body, a barrel, a heated injection nozzle, an injection mold and a discharge cavity, wherein the barrel and the injection mold are mounted on the machine body, and the barrel is provided with a heated injection nozzle, and a material is injected into the injection mold through the heated injection nozzle, and the material forms an automobile fender in the injection mold, and the discharge cavity is arranged at the injection mold of the machine body, so that the automobile fender can be discharged from the discharge cavity conveniently;

[0008] A support frame is placed in the cavity of the discharge cavity, and a filter screen cover is installed in the frame of the support frame.

DETAILED DESCRIPTION

[0026] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0027] like Figure 1 - Figure 5 As shown, an injection molding machine for producing automobile fenders has a reasonable structure and layout and complete functions. It mainly includes a machine body 1, a barrel 2, a heated injection molding nozzle 3, an injection mold 4 and a discharge cavity 5.

[0028] The machine body 1 is the support and foundation of the whole equipment, which is stable and reliable, ensuring the smooth progress of the whole production process. The barrel 2 is installed at a suitable position of the machine body 1 as a storage and conveying component for injection molding raw materials, which is convenient for adding and conveying raw materials to subsequent processing steps.

[0029] At the outlet of the barrel 2, a heated injection nozzle 3 is provided. This component melts the raw material by heating and accurately injects it into the injection mold 4. The injection mold 4 is carefully designed and manufactured to accurately shape and size the car fender.

[0030] After the injection molding is completed, the automobile fender will be cooled and solidified in the injection mold 4. At this time, the discharge cavity 5 plays an important role. The discharge cavity 5 is opened at the injection mold 4 of the body 1, which facilitates the automobile fender to be smoothly taken out from the mold.

[0031] In order to further optimize the discharging process, a support frame 6 is also placed in the discharging chamber 5. The support frame 6 is set in a rectangular parallelepiped frame and is fixed to the machine body 1 by bolts to ensure its stability and reliability. A filter screen cover 7 is installed in the frame of the support frame 6. The cross section of the filter screen cover 7 is designed in a "convex" shape, and its corner is an arc-shaped portion 8. This design not only enhances the structural strength, but also makes the overall appearance more beautiful.

[0032] The filter screen cover 7 is provided with a sliding cloth 9 inside, which is sewn on the filter screen cover 7 and has a certain inclination angle ranging from 10 to 45 degrees. This design allows the automobile fender to slide out smoothly after falling on the sliding cloth 9 and enter the subsequent collection or processing process through the discharge port.

[0033] In order to enhance the protection of the car fender, a plurality of mounting holes 10 are provided on the support frame 6. Slide bars 11 are installed in these mounting holes 10. Two limit rings 13 are provided on each slide bar 11, and a buffer spring 14 is installed between the two limit rings 13. In addition, a limiting rod 12 is provided between the two parallel slide bars 11. The limiting rod 12 is perpendicular to the slide bars 11 and supports the arc portion 8 of the filter screen cover 7. When the car fender falls from the injection mold 4, the limiting rod 12 and the buffer spring 14 can provide buffer protection to avoid damage.

[0034] The injection molding machine for automobile fender production can not only efficiently complete the injection molding production process, but also protect the automobile fender, optimize the discharge process, and improve production efficiency. At the same time, its proprietary structure and design also make the injection molding machine have a wide range of application prospects in the field of automobile parts manufacturing.

[0035] Working process: Raw materials are added into barrel 2. Barrel 2 serves as a storage and delivery component for raw materials, ensuring a stable supply of raw materials. At the outlet of barrel 2, the heated injection nozzle 3 starts working. It melts the raw materials by heating them to a state suitable for injection molding.

[0036] Next, the molten raw material is precisely injected into the injection mold 4. The injection mold 4 is precisely designed and manufactured to accurately shape the shape and size of the car fender. During the injection process, parameters such as mold temperature, pressure and injection speed are strictly controlled to ensure product quality and consistency.

[0037] After the injection molding is completed, the car fender is cooled and solidified in the mold. When the cooling time reaches the preset value, the mold begins to open and the car fender is ready to be discharged.

[0038] At this time, the support frame 6 and the filter screen cover 7 in the discharge cavity 5 play an important role. The support frame 6 provides a stable support for the filter screen cover 7, while the filter screen cover 7 plays a filtering and guiding role. When the car fender falls from the mold onto the filter screen cover 7, the inclined design of the sliding cloth 9 allows the fender to slide out smoothly and enter the subsequent collection or processing process through the discharge port.

[0039] The buffer protection component in the discharge collection device plays a vital role in the whole process. When the automobile fender falls from the mold onto the sliding cloth 9, it will first contact the limiting rod 12. The limiting rod 12 holds up the arc portion 8 of the filter screen 7, providing a preliminary buffer for the fender. Subsequently, the fender continues to fall and contacts the buffer spring 14 on the sliding rod 11. The buffer spring 14 further slows down the falling speed of the fender through its elastic action, thereby avoiding impact and damage to the fender.

[0040] Through the design of this buffer protection component, the car fender is effectively protected during the discharge process, avoiding damage caused by impact and collision. This not only improves the product qualification rate, but also reduces production and maintenance costs.

[0041] The injection molding machine for automobile fender production achieves efficient production and protection of automobile fenders through its efficient and stable working process and proprietary buffer protection component design, providing strong support for the development of automobile parts manufacturing.

[0042] The standard parts used in the utility model can all be purchased from the market, and special-shaped parts can be customized according to the instructions and the drawings. The specific connection methods of each part adopt the conventional means such as mature bolts, rivets, welding, etc. in the existing technology. The machinery, parts and equipment all adopt the conventional models in the existing technology, and the circuit connection adopts the conventional connection method in the existing technology, which will not be described in detail here.

[0043] The above are only preferred specific implementation methods of the utility model, but the protection scope of the utility model is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the utility model, who makes equivalent replacements or changes based on the technical scheme and utility model concept of the utility model, should be covered by the protection scope of the utility model.
