Description

Technical Field

[0001] This utility model relates to the field of molding machine technology, and in particular to a molding machine for processing plastic shells for electronic keyboards. Background Technology

[0002] In the field of processing and manufacturing plastic shells for electronic keyboards, traditional molding machines have many shortcomings in production processes and structural design, which seriously affect production efficiency and product quality.

[0003] In traditional molding machines, the design of various components lacks continuity in the feeding and molding process. The process from storage to melting, conveying, and molding of plastic raw materials is not continuous and efficient. Excessive residence time of materials during processing not only increases heat loss but also easily leads to changes in raw material properties, thus affecting the quality of the molded product. Simultaneously, the discontinuous process results in low production efficiency, making it difficult to meet the demands of large-scale production. Traditional molding machines mostly employ mechanical demolding, which often requires significant external force, resulting in long demolding times and potential damage between the plastic shell and the mold, leading to a higher product defect rate. Furthermore, mechanical demolding lacks flexibility and cannot adapt to the demolding requirements of plastic shells of different shapes and sizes. Traditional molding machines have low levels of automation, requiring significant manual intervention in the molding and demolding processes. Manual operation not only increases labor costs but also, due to human factors, makes it difficult to guarantee the stability and consistency of the production process, further impacting production efficiency and product quality.

[0004] To address the problems of traditional molding machines, this molding machine for processing plastic casings for electronic keyboards features an innovative design. Through an integrated feeding and molding structure, a flexible pneumatic demolding method, and automated production control, it effectively solves the shortcomings of traditional molding machines, such as discontinuous feeding and molding, low demolding efficiency, and low automation. This enables efficient and continuous production of plastic raw materials from storage to molding, improving production efficiency and product quality while reducing production costs.

[0017] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0018] Unless otherwise defined, the technical or scientific terms used in this invention shall have the ordinary meaning as understood by one of ordinary skill in the art to which this invention pertains.

[0019] Example 1 like Figures 1-2 As shown, this utility model provides a molding machine for processing plastic shells of electronic keyboards, including a molding module. One end of the molding module is equipped with a melting chamber 3 and a storage hopper 1. The storage hopper 1 is connected to the melting chamber 3 via a guide plate 2. The storage hopper 1 is used to store the plastic raw material to be processed. The guide plate 2 connects the storage hopper 1 and the melting chamber 3, ensuring that the raw material smoothly enters the melting chamber 3. One end of the melting chamber 3 is connected to a conveying pipe 4. Both the melting chamber 3 and the conveying pipe 4 are equipped with heating wires to heat the plastic raw material to a molten state. The molten plastic raw material is conveyed through the conveying pipe 4 at one end of the melting chamber 3. The conveying pipe 4 is located in the middle of the molding module and is used to convey the molten plastic raw material to the molding position. An outlet 5 is provided on the conveying pipe 4, and a fixed mold 9 is fixedly connected to one end of the outlet 5 to ensure that the plastic raw material can be accurately injected into the mold.

[0020] like Figure 3 As shown, the forming frame 6 is located above the forming module and contains a gear 14 and a transmission chain 15. The gear 14 meshes with the transmission chain 15, and the rotation of the transmission chain 15 drives the transmission rod 7 located below to move. The transmission chain 15 is connected to the transmission rod 7 through a clamp to ensure stable and reliable transmission.

[0021] like Figure 4 As shown, the molding module includes a movable mold 10, with a telescopic rod 8 at one end. The telescopic rod 8 is fixedly connected to a transmission rod 7, and the movement of the telescopic rod 8 drives the movable mold 10 to open and close. An air inlet 13 is provided below the movable mold 10, and an air valve 12 corresponding to the air inlet 13 is provided on the transmission rod 7 for pneumatic demolding. An air pump 11 is provided above the molding frame 6, and the transmission rod 7 has a hollow internal structure. The air pump 11 is connected to the hollow structure of the transmission rod 7 through an air pipe, providing the necessary gas pressure for pneumatic demolding.

[0022] A cooling chamber 16 is provided at the other end of the molding module for cooling and shaping the molded plastic shell. The cooling chamber 16 is positioned above the molding module to ensure good cooling effect. The conveyor belt 17 is positioned below the molding module to transport the cooled and shaped plastic shell to the next process.

[0023] The specific working principle of this utility model is as follows: Plastic raw material enters from the storage hopper 1 and passes through the guide plate 2 into the melting chamber 3. Heating wires inside the melting chamber 3 heat the raw material to a molten state. The molten plastic raw material is conveyed through the conveying pipe 4 to the outlet 5 and injected into the fixed mold 9. Simultaneously, the transmission chain 15 drives the transmission rod 7 to rotate cyclically along the molding frame 6 until the moving and fixed molds 9 correspond, driving the telescopic rod 8 to move forward and close the moving and fixed molds 9, completing the molding process.

[0024] After molding is complete, the telescopic rod 8 moves backward to separate the moving and stationary molds 9. The transmission chain 15 drives the transmission rod 7 through the cooling chamber 16, and the air pump 11 injects gas into the hollow structure of the transmission rod 7 through the air pipe. The gas enters the air inlet 13 below the moving mold 10 through the air valve 12 on the transmission rod 7, creating a small gap between the moving mold 10 and the plastic shell, causing the finished product to fall onto the conveyor belt 17.

[0025] Therefore, this utility model adopts the above-mentioned molding machine for processing plastic shells of electronic keyboards. Through the design of integrated feeding molding, flexible pneumatic demolding and automated production, it realizes efficient and continuous production of plastic raw materials from storage to molding, improves production efficiency and product quality, and reduces production costs.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the technical solution of this utility model, and these modifications or equivalent substitutions cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of this utility model.
