Description

Technical Field

[0001] This invention belongs to the field of injection mold technology, specifically relating to a multi-cavity metal terminal embedding molding assembly movable injection mold. Background Technology

[0002] In traditional injection mold manufacturing, for products requiring embedded metal terminals, the metal terminals are typically placed manually one by one into the mold cavity before injection molding to achieve the integration of plastic and metal terminals. This method was applicable to a certain extent in early production due to limited equipment and process conditions, and the process flow was relatively simple, easy to operate and adjust.

[0003] However, with increasingly complex product structures and ever-increasing demands from the manufacturing industry for product consistency, production efficiency, and cost control, manual insertion methods have gradually revealed a series of significant drawbacks. Especially in scenarios employing multi-cavity mold structures to increase single-batch molding capacity, manually inserting metal terminals one by one is not only inefficient but also highly susceptible to human error. Due to the small size and precise structure of metal terminals, manual placement easily leads to problems such as terminal misalignment, omissions, or slippage into mold gaps. This can result in poor injection molding at best, and at worst, mold damage, equipment downtime, and negatively impact overall production stability and yield.

[0004] Furthermore, after each injection molding cycle, the mold needs to wait for manual placement of the next batch of terminals, resulting in long periods of equipment downtime, reduced equipment utilization, and a lengthened overall production cycle. This severely restricts the efficient and automated continuous production process and fails to meet the current demands for large-volume, high-efficiency modern manufacturing.

[0005] Therefore, we propose a multi-cavity metal terminal embedding molding assembly movable injection mold to solve the above-mentioned technical problems. Summary of the Invention

[0006] In order to solve the technical problems existing in the prior art, the present invention proposes a multi-cavity metal terminal embedding molding assembly movable injection mold.

[0007] The technical solution adopted in this invention is as follows: A multi-cavity metal terminal embedding molding assembly movable injection mold includes a mold cover, a mold base, and multiple assembled movable carriers. The mold cover is sealed and closed onto the mold base. The mold cover and the mold base cooperate to form a molding cavity for mounting the assembled movable carriers. The outside of the mold base is provided with an injection port communicating with the molding cavity. The assembled movable carrier includes a carrier base plate and a movable cover plate slidably disposed on the carrier base plate. Multiple insert molding seats for implanting metal terminal inserts are embedded on both sides of the carrier base plate in the radial direction. Insertion grooves corresponding to the positions of the insert molding seats are respectively opened on both sides of the movable cover plate in the radial direction.

[0008] In a further technical solution, a limiting pin is also included, which is movably disposed inside the vehicle seat plate. The lower end of the limiting pin is installed inside the vehicle seat plate by a spring, and the upper end extends out of the vehicle seat plate. The bottom surface of the movable cover plate is provided with an opening limiting groove and a closing limiting groove that cooperate with the limiting pin. The side of the opening limiting groove and the closing limiting groove that are close to each other is provided with a downward inclined surface.

[0009] In a further technical solution, a pressure plate is bolted to the bottom of the vehicle seat plate, and the spring is mounted on the pressure plate.

[0010] In a further technical solution, the mold base is provided with multiple guide pillars on the top surface of the molding cavity, and the combined mobile carrier is provided with positioning holes that cooperate with the guide pillars.

[0011] In a further technical solution, handles are provided at both ends of the vehicle seat plate.

[0012] In a further technical solution, buffer blocks are provided at both ends of the vehicle seat plate.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: 1. This invention utilizes multiple combined mobile carriers in rotation. When one combined mobile carrier completes the insertion of the metal terminal insert and is installed into the mold base, it is injection molded through mold closing. Meanwhile, the remaining combined mobile carriers can be pre-loaded with metal terminal inserts by an automated pin insertion machine outside the mold. That is, the next set of combined mobile carriers is prepared simultaneously during the molding process. After the current molding cycle is completed, the carriers are quickly replaced and put into the mold, forming an efficient continuous operation mode. This effectively reduces the standby time of the equipment, improves the equipment utilization rate and the overall production cycle, and meets the current needs of large-scale, high-efficiency modern manufacturing.

[0014] 2. The present invention provides a limiting pin that is movably installed inside the carrier seat plate, and combined with the opening limiting groove and closing limiting groove provided on the bottom surface of the movable cover plate, when the movable cover plate slides to the predetermined position, the limiting pin can automatically spring into the corresponding limiting groove under the action of the spring, thereby achieving effective limiting of the movable cover plate in the open and closed positions and limiting the sliding stroke of the movable cover plate.

[0015] 3. By setting a clamping plate at the bottom of the vehicle seat plate and connecting it to the vehicle seat plate with bolts, the present invention enables the modular assembly and disassembly of the combined mobile vehicle, thereby improving the convenience of later maintenance.

Detailed Implementation

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] See Figures 1-5This invention provides a multi-cavity metal terminal embedding molding assembly movable injection mold, including a mold cover 1, a mold base 2, and multiple assembled movable carriers. The mold cover 1 is sealed and closed on the mold base 2. The mold cover 1 and the mold base 2 cooperate to form a molding cavity for mounting the assembled movable carriers. The outside of the mold base 2 is provided with an injection port 3 communicating with the molding cavity. The assembled movable carrier includes a carrier base plate 4 and a movable cover plate 5 slidably disposed on the carrier base plate 4. Multiple insert molding seats 7 for implanting metal terminal inserts 6 are embedded on both sides of the carrier base plate 4 in the radial direction. The movable cover plate 5 has insertion grooves 8 on both sides in the radial direction corresponding to the positions of the insert molding seats 7.

[0020] The specific working principle of this injection mold is as follows: This injection mold mainly includes a mold cover 1, a mold base 2, and multiple combined movable carriers. The combined movable carriers are installed inside the mold base 2, and the mold cover 1 seals and closes onto the mold base 2, forming a molding cavity for injection molding. An injection port 3 is provided on the outside of the mold base 2 or the mold cover 1 for injecting molten plastic into the molding cavity. The combined movable carrier serves as the mounting and positioning carrier for the metal terminal insert 6. Its structure includes a carrier base plate 4 and a movable cover plate 5 slidably mounted on the carrier base plate 4. Multiple insert molding seats 7 are arranged along both radial sides of the carrier base plate 4 for placing the metal terminal insert 6, achieving multi-cavity injection molding and effectively increasing single-batch production capacity. The movable cover plate 5 has insertion slots 8 corresponding to the insert molding seats 7. In actual operation, the operator or automated equipment slides the movable cover plate 5 to align the insertion slots 8 with the insert molding seats 7, quickly inserting the metal terminal insert 6 using existing automated pin insertion machines, significantly reducing human error and improving work efficiency. Subsequently, the movable cover plate 5 is slid again, causing the insertion slot 8 and the insert molding seat 7 to be misaligned. The movable cover plate 5 covers the insert molding seat 7 and simultaneously limits and fixes the implanted metal terminal insert 6, preventing it from shifting or falling off during mold closing or injection molding. It is worth mentioning that multiple combined mobile carriers are used in rotation. After one combined mobile carrier completes the implantation of the metal terminal insert 6, it is loaded into the mold base 2, and injection molding is performed through mold closing, realizing the integration of the metal terminal insert 6 with the plastic part. Simultaneously, the remaining combined mobile carriers can be pre-loaded with metal terminal inserts 6 outside the mold by an automated pin insertion machine. That is, the next set of combined mobile carriers is prepared simultaneously during the molding process, and quickly replaced after the current molding cycle, forming an efficient continuous operation mode. This effectively reduces equipment downtime, improves equipment utilization and overall production cycle time, and meets the current demands of large-scale, high-efficiency modern manufacturing.

[0021] In one specific implementation, see Figure 4It also includes a limiting pin 9 that is movably disposed inside the vehicle seat plate 4. The lower end of the limiting pin 9 is installed inside the vehicle seat plate 4 by a spring 10, and the upper end extends out of the vehicle seat plate 4. The bottom surface of the movable cover plate 5 is provided with an opening limiting groove 11 and a closing limiting groove 12 that cooperate with the limiting pin 9. The opening limiting groove 11 and the closing limiting groove 12 are both provided with a downward inclined surface on the side that is close to each other.

[0022] By movably setting a limiting pin 9 inside the carrier seat plate 4, and combining it with the opening limiting groove 11 and closing limiting groove 12 provided on the bottom surface of the movable cover plate 5, when the movable cover plate 5 slides to the predetermined position, the limiting pin 9 can automatically spring into the corresponding limiting groove under the action of the spring 10, thereby effectively limiting the movable cover plate 5 in the open and closed positions and limiting the sliding stroke of the movable cover plate 5. Furthermore, the downwardly inclined slope provided on the side close to the opening limiting groove 11 and the closing limiting groove 12 can squeeze the limiting pin 9 downwards during the sliding process when the movable cover plate 5 slides between the open and closed positions, thereby causing the limiting pin 9 to exit the groove and automatically releasing the limiting state, ensuring a smooth transition of the movable cover plate 5 during the sliding switching process.

[0023] In one specific implementation, see Figure 4 The bottom of the vehicle seat plate 4 is connected to a pressure plate 14 by bolts 13, and the spring 10 is installed on the pressure plate 14.

[0024] By setting a clamping plate 14 at the bottom of the vehicle seat plate 4 and connecting it to the vehicle seat plate 4 with bolts 13, the modular assembly and disassembly feature of the combined mobile vehicle is realized, which improves the convenience of later maintenance.

[0025] In one specific implementation, see Figure 1 , Figure 2 and Figure 3 The mold base 2 has multiple guide posts 15 on its top surface inside the molding cavity, and the combined mobile carrier has positioning holes 16 that cooperate with the guide posts 15.

[0026] By setting multiple guide pillars 15 in the molding cavity of the mold base 2 and opening positioning holes 16 on the combined mobile carrier to match them, quick and accurate positioning and matching can be achieved when the combined mobile carrier is placed into the mold base 2, simplifying the positioning operation process, improving the efficiency of carrier replacement, and ensuring the stability of mold matching and the consistency of molded products.

[0027] In one specific implementation, see Figure 2 The vehicle seat plate 4 is provided with handles 17 at both ends.

[0028] Handles 17 are provided at both ends of the vehicle seat plate 4, which makes it easy for operators to hold and carry, improves the efficiency of installation and disassembly of the combined mobile vehicle, reduces the labor intensity of operators, and enhances the safety and convenience of operation.

[0029] In one specific implementation, see Figure 2 Both ends of the vehicle seat plate 4 are provided with buffer blocks 18.

[0030] The vehicle base plate 4 is equipped with buffer blocks 18 at both ends, which can effectively buffer the impact force during the installation and disassembly of the combined mobile vehicle, reduce equipment wear and damage, extend equipment service life, and improve the stability and reliability of equipment operation.
