Description

Technical Field

[0001] This utility model relates to the field of plug injection molding technology, and in particular to a right-angle plug injection mold. Background Technology

[0002] Currently, plastic electrical plugs are generally manufactured using injection molding. In mold design, the upper and lower mold plates are the core components. During production, the electrical wire is usually prepared first, and then the plastic is encapsulated and molded using the injection molding process to finally form a complete plug product.

[0003] Because plastic materials shrink unevenly during the cooling and curing stage, and the right-angle structure of the right-angle plug is prone to structural interference during the molding process, the combined effect of these two factors can easily lead to serious defects such as scratches, local deformation, and even breakage on the product surface. This not only significantly increases the product defect rate and production costs, but also significantly reduces production efficiency. Utility Model Content

[0004] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a right-angle plug injection mold that enables efficient demolding, reduces product tearing, deformation, and breakage, lowers the defect rate, and improves production efficiency and product quality.

[0005] According to an embodiment of the present invention, a right-angle plug injection mold includes an upper mold having multiple upper cavities and injection runners; a lower mold having multiple lower cavities, the upper and lower cavities forming an injection cavity, the injection runners communicating with the injection cavity for injection molding; two mesh tail inserts, each having multiple mesh tail cavities communicating with the injection cavity, one mesh tail insert being detachably embedded in the upper mold and the other mesh tail insert being detachably embedded in the lower mold; two cable inserts, each having multiple cable grooves communicating with the mesh tail cavities, one cable insert being detachably embedded in the upper mold and the other cable insert being detachably embedded in the lower mold; and a limiting pin, detachably embedded between the upper and lower molds, the limiting pin having multiple limiting grooves adapted to the product interface, the limiting pin being configured to cause the product to be demolded synchronously by insertion and removal.

[0006] The right-angle plug injection mold according to the present invention has at least the following beneficial effects: it decomposes the wire mesh tail forming area and the cable positioning area into independently replaceable insert modules, so that the stress concentration area at the right-angle turn can obtain precise temperature control and shrinkage compensation capability. At the same time, it introduces a limiting pin with a limiting groove, so that the product can be demolded synchronously during the separation of the parting surface. This effectively eliminates the shear stress generated at the right angle in the traditional ejection method, which not only ensures the forming accuracy of complex geometric shapes, but also avoids structural damage during the demolding process. This ensures that the product always maintains a force balance during the demolding process, thereby improving production efficiency and product quality.

[0012] According to some embodiments of the present invention, a pneumatic ejector rod includes: a rod body, which is movably inserted into a through hole, and the rod body has an air channel along its length. The rod body moves toward and away from the product so that the air channel communicates with and closes the injection cavity; a first end, which is located at the end of the rod body near the product and is configured to abut against the cavity wall of the injection cavity to limit the position of the rod body on the through hole when the injection cavity is sealed with the air passage; and a second end, which is located at the end of the rod body opposite to the first end and is configured to abut against the lower mold to limit the position of the rod body on the through hole when the injection cavity is connected with the air passage.

[0013] According to some embodiments of the present invention, a lifting mechanism is also included. The lifting mechanism is connected to the lower mold and to a limiting pin. The lifting mechanism is used to separate the limiting pin from the lower mold so that the product is separated from the lower mold.

[0036] In the description of this utility model, unless otherwise explicitly defined, the terms "setting", "installation", "connection", etc. should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in combination with the specific content of the technical solution.

[0037] Please refer to Figures 1 to 7This embodiment discloses a right-angle plug injection mold, including an upper mold 100, a lower mold 200, two wire mesh inserts 300, two cable inserts 400, and a limiting pin 500. The upper mold 100 is provided with multiple upper cavities 110 and injection channels 120, and the lower mold 200 is provided with multiple lower cavities 210. The upper cavities 110 and lower cavities 210 surround to form an injection cavity. The injection channels 120 communicate with the injection cavity to inject molding into the injection cavity. Both mesh tail inserts 300 are provided with multiple mesh tail cavities 310, which are connected to the injection cavity. One mesh tail insert 300 is detachably embedded in the upper mold 100, and the other mesh tail insert 300 is detachably embedded in the lower mold 200. Both cable inserts 400 are provided with multiple cable grooves 410, which are connected to the mesh tail cavity 310. One cable insert 400 is detachably embedded in the upper mold 100, and the other cable insert 400 is detachably embedded in the lower mold 200. The limiting pin 500 is detachably embedded between the upper mold 100 and the lower mold 200. The limiting pin 500 is provided with multiple limiting grooves 510 that are adapted to the product interface. The limiting pin 500 is configured to cause the product to be demolded synchronously by insertion and removal.

[0038] like Figures 1 to 4 As shown, the upper mold 100 has an upper cavity 110, and the lower mold 200 has a lower cavity 210. The upper cavity 110 and the lower cavity 210 together form an injection cavity. Two mesh tail inserts 300 are respectively installed on the upper mold 100 and the lower mold 200, and can be disassembled and installed separately. The mesh tail inserts 300 have mesh tail grooves to form the mesh part of the tail of the right-angle plug 10. Two cable inserts 400 are also respectively installed on the upper mold 100 and the lower mold 200, and can be disassembled and installed separately. The cable inserts 400 have cable grooves 410 for fixing cables and ensuring accurate cable positioning during injection molding. A limiting pin 500 is simultaneously embedded between the upper mold 100 and the lower mold 200. It has multiple limiting grooves 510 that can be adapted to the metal interface of the right-angle plug 10. During injection molding, the metal interface is inserted into the limiting grooves 510. Therefore, the tail forming area and cable positioning area are decomposed into independently replaceable insert modules, which enables precise temperature control and shrinkage compensation in the stress concentration area at the right angle. At the same time, a limiting pin 500 with a limiting groove 510 is introduced to achieve synchronous demolding of the product during the separation of the parting surface. This effectively eliminates the shear stress generated at the right angle in the traditional ejection method, which not only ensures the forming accuracy of complex geometric shapes, but also avoids structural damage during demolding. This ensures that the product always maintains a force balance during demolding, improving production efficiency and product quality.

[0039] It should be noted that the number of upper cavity 110, lower cavity 210, tail cavity 310, cable groove 410 and limiting groove 510 are the same and correspond one-to-one. The injection cavity and tail cavity 310 are interconnected to form a complete right-angle plug 10.

[0040] In some specific embodiments of this utility model, the limiting pin 500 is disposed through the upper mold 100, and both ends of the limiting pin 500 extend to the outer side of the upper mold 100 to form an operating part 520, so as to facilitate the operator to hold and apply force to achieve overall demolding. Figure 1 As shown, the limiting pin 500 passes through the lower mold 200 in the left and right direction, and the two ends of the limiting pin 500 extend to the outside of the upper mold 100 to form the operating part 520. The operator can directly apply force to achieve overall demolding, thereby effectively solving the deformation problem caused by uneven force during the demolding process of the right-angle plug 10, and improving demolding efficiency and product yield.

[0041] In some specific embodiments of this utility model, one of the limiting pin 500 and the lower mold 200 is provided with a first positioning post 220, and the other is provided with a first positioning hole 530 adapted to the first positioning post 220. The first positioning post 220 and the first positioning hole 530 are inserted and fitted together to achieve precise alignment of the limiting pin 500. Figure 7 As shown, in this specific embodiment, the limiting pin 500 is provided with a first positioning hole 530, and the lower mold 200 is provided with a first positioning post 220.

[0042] In some specific embodiments of this utility model, one of the upper mold 100 and the lower mold 200 is provided with a plurality of second positioning posts 130, and the other is provided with a plurality of second positioning holes 230 adapted to the first positioning posts 220. The plurality of second positioning posts 130 and the plurality of second positioning holes 230 are inserted and fitted together to achieve precise alignment of the upper mold 100 and the lower mold 200. Figure 2 and Figure 3 As shown, in this specific embodiment, the upper mold 100 is provided with four second positioning posts 130, and the lower mold 200 is provided with four second positioning holes 230. The four second positioning posts and the four second positioning holes correspond one-to-one.

[0043] In some specific embodiments of this utility model, the limiting pin 500 includes a pin body 540 and a plurality of limiting blocks 550. The plurality of limiting blocks 550 are evenly arranged on the pin body 540 along the length direction. The plurality of limiting blocks 550 are located on the same end face of the pin body 540. Each limiting block 550 is provided with a limiting groove 510.

[0044] like Figure 4As shown, the pin body 540 is embedded between the upper mold 100 and the lower mold 200 along the left-right direction. A limiting block 550 is located at the rear end of the pin, with multiple limiting blocks 550 evenly distributed along the left-right direction. Specifically, each limiting block 550 has a limiting groove 510 on its right end face to ensure uniform positioning of each metal interface during injection molding. Simultaneously, the modular design facilitates adjustments to the pin body 540 for different product specifications, allowing for replacement of the limiting blocks 550, thus improving the mold's adaptability and economy, and providing technical support for flexible production of multiple varieties and small batches.

[0045] From the perspective of application principle, this technology achieves the dispersion and control of local stress through the split limiting block 550 structure. The independently set grooves of each limiting block 550 can form a multi-point uniform force on the product during demolding, which greatly reduces the local stress on the product during demolding.

[0046] In some specific embodiments of this utility model, an air blowing mechanism 600 is also included. The air blowing mechanism 600 is connected to the upper mold 100 and the lower mold 200. The output end of the air blowing mechanism 600 is connected to the injection cavity. The air blowing mechanism 600 is used to assist in product demolding.

[0047] In some specific embodiments of this utility model, the air blowing mechanism 600 includes: a through hole 610, which is disposed on the lower mold 200, one end of which is connected to the injection cavity, and the other end is connected to the compressed air supply device 612 through the air passage pipe 611; and a pneumatic ejector rod 620, which is slidably inserted in the through hole 610, extends in the same direction as the through hole 610, and moves toward the product and away from it, so as to connect and seal the injection cavity with the air passage pipe 611.

[0048] like Figure 5 and Figure 6 As shown, a through hole 610 extending in the vertical direction is provided in the lower mold 200. The pneumatic ejector rod 620 is movably inserted in the through hole 610 in the vertical direction. Thus, the sliding of the pneumatic ejector rod 620 in the through hole 610 constitutes an intelligent switching valve. When it is pushed upward, the air passage is opened to allow compressed air to enter the cavity. When it is reset downward, the air passage is closed. This non-contact demolding force can effectively avoid the damage to the product surface caused by traditional mechanical ejection. Especially for products with complex structures such as right-angle plugs 10 and mesh tails that are prone to mold jamming, air-assisted demolding can realize the synchronous release of various parts of the product from the cavity, significantly improving the demolding success rate and product yield.

[0049] Specifically, the compressed air supply device 612 is a common device such as an air pump, which will not be described in detail here.

[0050] In some specific embodiments of this utility model, the pneumatic ejector rod 620 includes: a rod body 621, which is movably inserted into a through hole 610. The rod body 621 has an air channel 6211 along its length. The rod body 621 moves towards and away from the product so that the air channel 6211 communicates with and is closed to the injection cavity; a first end 622, which is located at the end of the rod body 621 near the product. The first end 622 is configured to abut against the cavity wall of the injection cavity to limit the position of the rod body 621 on the through hole 610 when the injection cavity is sealed with the air channel 611; and a second end 623, which is located at the end of the rod body 621 opposite to the first end 622. The second end 623 is configured to abut against the lower mold 200 to limit the position of the rod body 621 on the through hole 610 when the injection cavity is connected to the air channel 611.

[0051] like Figure 6 As shown, the rod 621 extends vertically, with a first end 622 and a second end 623 respectively located at the upper and lower ends of the rod 621. The lower mold 200 is provided with a first limiting platform adapted to the first end 622 and a second limiting platform adapted to the second end 623. An air channel 6211 is provided inside the rod 621. In conjunction with the limiting structure of the first end 622 and the second end 623, a single component can simultaneously perform the dual functions of sealing the injection cavity and guiding the air passage. Specifically, when the rod 621 is in the injection position, the first end 622 is in close contact with the cavity wall of the injection cavity to form a seal, preventing the plastic melt from entering the through hole 610. During demolding, the rod 621 is lifted up, and the air channel 6211 connects the injection cavity and the air passage 611. Compressed air is evenly applied to the product through the air channel 6211 inside the rod 621, providing a stable and uniform demolding auxiliary force, effectively solving the problem of easy deformation during demolding of the thin-walled right-angle plug 10.

[0052] It should be noted that the rod 621 is movably installed in the through hole 610. When compressed air is blown into the through hole 610 through the air passage 611, the rod 621 is pushed upward by the compressed air, thereby opening the air passage 6211.

[0053] In some specific embodiments of this utility model, a lifting mechanism 700 is also included. The lifting mechanism 700 is connected to the lower mold 200 and is connected to the limiting pin 500. The lifting mechanism 700 is used to separate the limiting pin 500 from the lower mold 200 so that the product is separated from the lower mold 200.

[0054] In some specific embodiments of this utility model, the lifting mechanism 700 includes a plurality of lifting components 710, which are evenly distributed along the length direction of the limiting pin 500, and are used to uniformly push out the limiting pin 500.

[0055] In some specific embodiments of this utility model, the lifting assembly 710 includes: a lifting rod 711, which is slidably disposed on the lower mold 200; a driving member 712, which is disposed at the end of the lifting rod 711 away from the product; and a lifting member 713, which is disposed at the end opposite to the lifting rod 711 and the driving member 712, and is movably embedded in the cavity wall of the injection cavity. The driving member 712 controls the lifting rod 711 to drive the lifting member 713 to push against the product in the opposite direction from the injection cavity.

[0056] like Figure 7 As shown, two lifting components 710 are symmetrically arranged on opposite sides of the first positioning post 220. The multiple lifting components 710 are evenly distributed along the length direction, forming a multi-point balanced ejection system. This ensures that all parts of the product simultaneously detach from the mold cavity. When the driving component 712 pushes the lifting rod 711, it drives the lifting component 713 to apply a uniform ejection force to the product. At the same time, the linkage limit pin 500 achieves overall separation. Furthermore, the lifting component 713 is movably embedded in the cavity wall of the injection cavity, which not only ensures the integrity of the lower cavity 210 during injection molding but also provides a precise ejection contact surface during demolding. This effectively solves the demolding difficulty problem caused by the special structure of the right-angle plug 10 and improves production efficiency.

[0057] Specifically, the drive component 712 is a cylinder.

[0058] Furthermore, the lifting mechanism 700 and the air-blowing mechanism 600 can be combined to achieve the coordination of two demolding methods through timing control. Specifically, in the initial stage of demolding, the lifting component 713 of the lifting mechanism 700 first applies a precise and controllable mechanical ejection force to the product, creating an initial separation gap between the product and the cavity. Subsequently, the air-blowing mechanism 600 immediately introduces compressed air, utilizing the uniformity of air pressure to completely detach the product from the mold. This leverages both the accurate positioning advantage of mechanical ejection and the uniform force characteristic of air-assisted demolding, effectively solving the problem of traditional single demolding methods struggling to balance demolding force and product protection. Simultaneously, the combined arrangement of the two mechanisms improves the mold's adaptability, allowing for flexible adjustment of the coordination sequence and force of the two demolding methods according to the demolding requirements of different products, thereby improving product yield and production efficiency.

[0059] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
