Description

Technical Field

[0001] This utility model relates to a manual wire insertion mechanism for injection mold wire frame, belonging to the field of in-mold wire coating technology. Background Technology

[0002] Wire re-coating products are widely used in the electronics and automotive industries in everyday life. Traditional production processes involve operators manually inserting the wire into the mold cavity and adjusting its position, followed by mold closing, injection molding, mold opening, manual removal, and then repeating the wire insertion process. Due to reliance on manual operation, these molds are generally limited to four cavities per mold, resulting in low production capacity. When facing large-volume product demand, additional molds and injection molding machines need to be developed, increasing costs. Furthermore, manual wire insertion not only prolongs the molding cycle but may also cause the raw material to decompose and carbonize at high temperatures inside the injection barrel due to prolonged downtime, affecting product quality. To solve these problems, we designed a manual, rapid wire insertion frame mechanism. This mechanism aims to replace automated operations with manual or robotic arms, quickly and accurately inserting wire, shortening the insertion cycle, and enabling the development of multi-cavity coating molds. This increases production capacity, reduces worker workload, minimizes product quality issues caused by improper manual operation, and lowers mold development costs. Compared to high-cost automated insertion solutions, especially when customer demand is low, the manual, rapid wire insertion frame mechanism avoids the risks of high cost investment and customer loss. The mechanism works by equipping each mold with one or two wire frames. After the mold is opened, the wire frames are removed manually or by a robot and placed on the worktable. Then, the wire frames with the wire inserted are placed back into the mold for mold closing and production. While the injection molding machine is closing the mold and injecting the wire, the worker removes the formed wire from the wire frame and re-inserts it into the wire frame to prepare for the next production cycle. Utility Model Content

[0003] The purpose of this invention is to provide a manual wire insertion mechanism for injection molds, which can solve the problems of low efficiency, high cost, long molding cycle, high product defect rate, and high mold development cost of traditional manual wire insertion.

[0004] To solve the above-mentioned technical problems, the present invention is implemented using the following technical solution.

[0005] On one hand, this utility model provides a manual wire insertion mechanism for an injection mold wire frame, including a wire frame, multiple wires installed within the wire frame, and a mold; the wire frame is provided with a wire reference block, a first support block, and a second support block, which support the wires; the wire reference block is connected to an adjusting block, which is mounted on a scale and slides on the scale to determine the position of the wires on the mold using the scale on the scale; the scale is equipped with a foolproof block to prevent the wire frame from being installed backwards, and the foolproof block is provided with a wire frame positioning screw; the mold has a positioning groove that is adapted to the wire frame positioning screw, so that the wire frame can be quickly positioned on the mold.

[0006] Preferably, the wire is made of plastic.

[0007] Preferably, one end of the scale has a protrusion and is symmetrically mounted on the wire frame, and a foolproof block is installed on the protrusion.

[0008] Preferably, the center of the anti-mistake block is asymmetrical about the left and right sides of the baseline.

[0009] Preferably, the mold includes a wire positioning block, a mold core located at the center, a cavity, and a male template. The wire is placed in the cavity, the wire positioning block and the mold core are fixed on the wire frame, and the male template is screwed with a wire frame bracket for supporting the wire frame.

[0010] Preferably, the wire positioning block is located between the first support block and the second support block, and is placed outside the molding sealant of the mold core.

[0011] Preferably, the wire frame bracket and the wire frame frame are mounted on the mold.

[0012] Preferably, the mold further includes an ejector pin, an ejector plate, a base plate, and an ejector rod, wherein the ejector pin is fixed on the ejector plate, and the ejector rod passes through a through hole in the base plate and is fixed at the bottom of the ejector plate.

[0013] Compared with the prior art, the beneficial effects achieved by this utility model are as follows:

[0014] This invention relates to a manual wire insertion mold wire frame mechanism, achieving high efficiency and precision in the wire insertion process. The wire reference block, first support block, and second support block inside the wire frame work together to support the wire, ensuring it maintains the correct position during injection molding, thereby improving the consistency and quality of the molded product. The connection between the wire reference block and the adjusting block allows the adjusting block to slide along a scale. This design enables precise adjustment of the wire position according to the needs of different molds, further ensuring correct alignment of the wire within the mold. This is crucial for improving product accuracy and reducing scrap rates.

[0015] The anti-misalignment block installed on the scale not only prevents the wire frame from being installed backwards, but also enables rapid positioning of the wire frame through its wire frame positioning screws matching the positioning slots on the mold. This rapid positioning mechanism significantly reduces mold changeover time and production preparation time, improving production efficiency. At the same time, due to precise positioning, it reduces product quality problems caused by inaccurate positioning, thereby lowering production costs and enhancing the product's market competitiveness.

[0016] Furthermore, the design of this device allows for the rapid insertion of wire racks manually or by robotic arms without increasing the cost of automated equipment. This is an economical and effective solution for customers with low demand who are not suited to investing in expensive automated equipment. Attached Figure Description

It should be understood that the embodiments of the present invention and the specific features therein are detailed descriptions of the present invention, rather than limitations thereof. In the absence of conflict, the embodiments of the present invention and the technical features therein can be combined with each other.

[0025] The term "and / or" simply describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, or B alone. Additionally, the character " / " generally indicates that the preceding and following related objects have an "or" relationship. Example 1

[0026] See Figure 1 , Figure 5 and Figure 6 This embodiment introduces a manual wire insertion mechanism for injection molds, designed to improve the efficiency and accuracy of wire insertion into injection molds. The mechanism includes a wire frame 2, multiple wires 1 installed within the wire frame 2, and a mold 21. The wire frame 2 contains a wire reference block 3, a first support block 4, and a second support block 6. These components work together to support the wires 1, ensuring they maintain their correct position during injection molding.

[0027] See Figure 2 and Figure 6 The wire reference block 3 is connected to the adjusting block 9, which is mounted on the scale 7 and can slide on the scale 7. The scale 7 is used to determine the precise position of the wire 1 within the mold 21 to meet the positioning requirements of wires 1 of different lengths. The scale 7 is equipped with a foolproof block 8 to prevent the wire frame from being installed backwards. The foolproof block 8 allows the scale 7 to be symmetrically installed on the wire frame 2, while also helping to prevent the wire frame from being installed backwards, ensuring correct installation. The center of the foolproof block 8 is asymmetrical around the reference line, further improving the foolproof effect. In addition, the foolproof block 8 is equipped with a wire frame positioning screw 5, which matches the positioning groove 14 on the mold 21. This design allows the wire frame 2 to be quickly and accurately positioned on the mold 21.

[0028] See Figure 3 and Figure 4 The wire 1 is made of plastic, a material choice that helps improve the wire's flexibility and durability. The wire reference block 3 and the adjusting block 9 are connected by screws, a connection method that is both secure and easy to adjust. The mold 21 further includes a wire positioning block 10, a mold core 11 located at the center, a cavity 12, and a male template 13.

[0029] In this design, wire 1 is placed inside cavity 12. Wire positioning block 10 and mold core 11 are fixed to wire frame frame 2 by screws, while a wire frame bracket 15 for supporting wire frame frame 2 is screwed onto male mold plate 13. Wire positioning block 10 is located between first support block 4 and second support block 6, and is placed outside the molding sealant of mold core 11, which helps to ensure the correct position of the wire during injection molding.

[0030] Furthermore, the wire frame bracket 15 and the wire frame frame 2 are mounted together on the mold 21 to ensure the stability of the wire frame frame during the injection molding process. In addition, the mold 21 also includes an ejector pin 16, an ejector plate 17, a base plate 19, and an ejector rod 18. The ejector pin 16 is fixed to the ejector plate 17, and the ejector rod 18 passes through a through hole in the base plate 19 and is fixed to the bottom of the ejector plate 17. These components work together to eject the molded wire product from the mold after injection molding. The cooperation of the ejector plate 17 and the ejector rod 18 allows the product to smoothly detach from the cavity, improving production efficiency and reducing the need for manual operation.

[0031] In summary, the manual wire insertion mechanism for injection molds, through its unique design, enables rapid and accurate wire insertion, shortens the production cycle, increases capacity, reduces manual operation, and also reduces product quality problems caused by improper manual operation. It is an effective solution for wire insertion in injection molds.
