Description

Technical Field

[0001] The invention relates to a manual wire material implantation injection molding module wire rack mechanism and a wire material overmolding molding method, belonging to the technical field of wire material overmolding in injection molds. Background Art

[0002] Wire secondary coating products are widely used in the electronics and automotive industries in daily life. The traditional production process involves operators manually inserting wires into the mold cavity and adjusting the position, followed by mold closing, mold opening, manual removal, and then repeating the process of inserting wires. Due to reliance on manual operation, this type of mold is generally limited to one mold with four cavities, resulting in low production capacity. When faced with a large demand for products, additional duplicate molds and injection molding machines need to be developed, which increases costs. In addition, manual wire insertion not only prolongs the molding cycle, but may also cause the raw materials to decompose and carbonize in the barrel due to high temperature due to long downtime, affecting product quality. In order to solve these problems, we have designed a manual fast wire insertion wire rack mechanism, which aims to replace automated operations with manual or robotic arms, quickly and accurately insert wires, shorten the implantation cycle, and realize the development of one mold with multiple cavities. This can not only increase production capacity, reduce the labor intensity of workers, reduce product quality problems caused by improper manual operation, but also reduce mold development costs. Compared with high-cost automated implantation solutions, especially when customer demand is small, manual fast wire implantation wire rack mechanisms can avoid high cost investment and the risk of customer loss. The working principle of this mechanism is to equip each set of molds with one or two sets of wire racks. After the mold is opened, the wire racks are taken out manually or by a robot and placed on the workbench. Then the wire racks with wires implanted are put back into the mold for mold closing production. While the injection molding machine is closing the mold for injection molding, the worker removes the molded wire from the wire rack and re-implants it in the wire rack to prepare for the next cycle of production. Summary of the invention

DETAILED DESCRIPTION

[0018] The technical solution of the present invention is described in detail below through the accompanying drawings and specific embodiments. It should be understood that the embodiments of the present invention and the specific features in the embodiments are detailed descriptions of the technical solution of the present invention, rather than limitations on the technical solution of the present invention. The embodiments of the present invention and the technical features in the embodiments may be combined with each other unless there is a conflict.

[0019] The term "and / or" is only a description of the association relationship between related objects, indicating that there can be three relationships. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " generally indicates that the related objects are in an "or" relationship. Example 1

[0020] See also Figure 1 , Figure 5 and Figure 6 This embodiment introduces a manual wire implantation injection mold wire rack mechanism, which aims to improve the efficiency and accuracy of wire implantation injection molds. The mechanism includes a wire rack frame 2, a plurality of wires 1 installed in the wire rack frame 2, and a mold 21. A wire reference block 3, a first support block 4, and a second support block 6 are arranged inside the wire rack frame 2. The wire reference block 3, the first support block 4, and the second support block 6 jointly support the wire 1 to ensure that it maintains the correct position during the injection molding process.

[0021] See also Figure 2 and Figure 6, the wire reference block 3 is connected to the adjustment block 9, the adjustment block 9 is mounted on the ruler 7, and the adjustment block 9 can slide on the ruler 7, and the ruler 7 is used to determine the precise position of the wire 1 in the mold 21 to meet the positioning requirements of wires 1 of different lengths. An anti-fool block 8 is installed on the ruler 7 to prevent the wire rack from being installed in reverse. The setting of the anti-fool block 8 enables the ruler 7 to be installed on the wire rack frame 2 symmetrically, and at the same time, the anti-fool block 8 helps to prevent the wire rack from being installed in reverse, ensuring the correct installation of the wire rack. The center of the anti-fool block 8 is asymmetrical on the left and right of the reference line, which further improves the anti-fool effect. In addition, the anti-fool block 8 is provided with a wire rack positioning screw 5, which is compatible with the positioning slot 14 provided on the mold 21. This design enables the wire rack frame 2 to be quickly and accurately positioned on the mold 21.

[0022] See also Figure 3 and Figure 4 The wire 1 is made of plastic material, which helps to improve the flexibility and durability of the wire. The wire reference block 3 and the adjustment block 9 are connected by screws, which is both firm and convenient for adjustment. The mold 21 further includes a wire positioning block 10, a mold core 11 located at the center, a mold cavity 12 and a male mold plate 13.

[0023] The wire 1 is placed in the cavity 12, the wire positioning block 10 and the mold core 11 are fixed to the wire frame 2 by screws, and the male mold plate 13 is screwed with a wire frame bracket 15 for supporting the wire frame 2. The wire positioning block 10 is located between the first bracket 4 and the second bracket 6, and is placed outside the molding sealant of the mold core 11, which helps to ensure the correct position of the wire during the injection molding process.

[0024] Furthermore, the wire rack bracket 15 and the wire rack frame 2 are installed together on the mold 21 to ensure the stability of the wire rack frame during the injection molding process. In addition, the mold 21 also includes an ejector pin 16, an ejector plate 17, a bottom plate 19 and an ejector rod 18. The ejector pin 16 is fixed on the ejector plate 17, and the ejector rod 18 passes through the through hole in the bottom 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 the injection molding is completed. The coordinated use of the ejector plate 17 and the ejector rod 18 enables the product to be smoothly separated from the cavity, thereby improving production efficiency and reducing the need for manual operation.

[0025] In summary, the manual wire implantation injection mold wire rack mechanism achieves fast and accurate wire implantation through its unique design, shortens the production cycle, improves production capacity, reduces manual operation, and also reduces product quality problems caused by improper manual operation. It is an effective solution for wire implantation in injection molds. Example 2

[0026] A wire material overmolding method, comprising: Step S1, placing the wire 1 on the wire rack frame 2, and ensuring that the length direction of the wire 1 is aligned and positioned on the wire reference block 3; The function of the wire reference block 3 is to provide stable support and precise positioning for the wire 1, which is the key to ensure that the wire maintains the correct position during the subsequent injection molding process.

[0027] Step S2, adjusting the position of the adjustment block 9 connected to the wire reference block 3 on the wire rack frame 2 with reference to the scale 7; By adjusting the sliding of the block 9 on the ruler 7 , the position of the wire 1 in the mold 21 can be accurately controlled to meet the requirements of wires of different lengths.

[0028] Step S3, placing the wire frame 2 with the good wire 1 in the cavity 12 of the mold 21, and aligning the wire frame positioning screws on the wire frame 2 with the positioning grooves 14 in the mold 21, so that the wire frame 2 is placed in the correct position on the mold 21; During the placement process, the wire rack positioning screws 5 on the wire rack frame 2 need to be aligned with the positioning slots 14 in the mold 21 to ensure that the wire rack frame can be quickly and accurately placed at a predetermined position on the mold 21, thereby improving production efficiency and reducing positioning errors.

[0029] Step S4: After the wire rack frame 2 is placed in the correct position, the injection molding machine performs mold closing and injection molding on the mold 21; Here, the mold clamping device of the injection molding machine will close the mold 21, fix the wire frame 2 and the wire 1 therein in the cavity 12, and then inject the plastic material to complete the overmolding of the wire.

[0030] Step S5, after the injection molding is completed, the injection molding machine performs a mold opening operation again. At this time, the mold opening device of the injection molding machine opens the mold 21, and the ejector 18 pushes the ejector plate 17, so that the ejector 16 ejects the wire product from the cavity 12, completing the demoulding of the wire product; Step S6, taking the wire rack frame 2 with the formed wire product out of the mold 21, and taking out the formed wire product; Here, the formed wire product is separated from the wire rack frame 2 and prepared for subsequent processing or packaging.

[0031] Step S8: implant a new batch of wires into the wire rack frame 2 again to carry out the next round of production.

[0032] Here, this step marks the end of the production process and ensures that continuous production can proceed smoothly.

[0033] Through this method, the present invention can realize the rapid and accurate implantation of wires, shorten the implantation cycle of wires, improve production capacity, reduce the defective secondary plastic-coated products caused by the poor position of artificially implanted wires, and at the same time reduce the mold development cost, reduce the labor intensity of workers, and avoid the problems of raw material decomposition and carbonization caused by long downtime waiting for implantation, thereby improving product quality and production efficiency.

[0034] The embodiments of the present invention are described above in conjunction with the accompanying drawings, but the present invention is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the enlightenment of the present invention, ordinary technicians in this field can also make many forms without departing from the scope of protection of the purpose of the present invention and the claims, which all fall within the protection of the present invention.
