[0020] Please refer to Figures 1-6 The present application provides a technical solution: a connector mold with inlaid pins, comprising an upper support plate 1, a middle support seat 2, a side support frame 3 and a lower bottom plate 4, the upper surface of the lower bottom plate 4 is provided with a side support frame 3 on both sides, the upper end of the side support frame 3 is provided with a middle support seat 2, the upper end of the middle support seat 2 is provided with an upper support plate 1, and the upper support plate 1 and the middle support seat 2 are connected by fasteners.

[0021] The upper support plate 1 is connected to the middle support seat 2 by fasteners, ensuring that the two components are tightly fitted during high-pressure molding, preventing material leakage or displacement.

[0022] The middle support seat 2 is located between the upper support plate 1 and the lower bottom plate 4, and is responsible for evenly transmitting the pressure of the upper support plate 1 to the lower bottom plate 4, and usually contains a device for fixing the upper and lower mold cavities (i.e. inner mold).

[0023] The side support frame 3 is installed on both sides of the lower bottom plate 4, and the side support frame 3 provides additional lateral support. It helps to maintain the stability of the mold in the closed state and can withstand lateral forces, preventing deformation or damage caused by external forces.

[0024] The lower bottom plate 4 is the base platform of the mold, and the lower bottom plate 4 provides a stable mounting surface for all the components above it.

[0025] The middle support seat 2 comprises an upper clamping seat 21 and a lower clamping seat 22, the upper clamping seat 21 and the lower clamping seat 22 are respectively provided with an upper inner mold 5 and a lower inner mold 6, the upper inner mold 5 and the lower inner mold 6 are respectively installed between the upper clamping seat 21 and the lower clamping seat 22 by fasteners, and a flow guide 7 is arranged between the upper inner mold 5 and the lower inner mold 6, and the flow guide 7 is communicated with the lower inner mold 6.

[0026] The middle support seat 2 is composed of two main parts, namely the upper clamping seat 21 and the lower clamping seat 22. The upper clamping seat 21 and the lower clamping seat 22 provide structural support and are also used to fix the upper inner mold 5 and the lower inner mold 6 respectively. Precise machining ensures the precise alignment between the upper inner mold 5 and the lower inner mold 6.

[0027] The upper inner mold 5 is installed in the upper clamping seat 21, and the lower inner mold 6 is installed in the lower clamping seat 22, and both are connected by fasteners. The two are tightly connected to ensure the sealing of the mold cavity during the molding process and prevent material leakage.

[0028] The flow guide 7 is located between the upper inner mold 5 and the lower inner mold 6, and is used to guide the molten material from the feed port to flow between the upper inner mold 5 and the lower inner mold 6, and to be evenly distributed to each position that needs to be filled, to fill the pins 9, and to form a connector assembly.

[0029] The lower inner mold 6 and the upper inner mold 5 are provided with cavities for placing the placement blocks 8, and the lower inner mold 6 is provided with a plug-in mold cavity corresponding to the cavities of the placement blocks 8, and the three cavities are connected by the pins 9.

[0030] The placement blocks 8 are placed in the cavities between the lower inner mold 6 and the upper inner mold 5 to provide a fixed position for the pins 9 and ensure that the pins remain in the correct position during the molding process; the placement blocks 8 are usually made of high-temperature-resistant and high-strength materials to withstand the pressure and temperature changes during the molding process.

[0031] The plug-in mold cavity is provided on the lower inner mold 6 corresponding to the cavity on the placement block 8, and the placement block 8 is located inside to limit the position of the pin 9, ensure that the pin 9 is in the precise position, and ensure the quality and consistency of the product.

[0032] Further, the upper support plate 1 is provided with a material flow guide assembly 14, which includes a ring support 141 and a flow guide pipe group 142, and the ring support 141 and the flow guide pipe group 142 are correspondingly arranged, and the other end of the flow guide pipe group 142 is connected with the feed port of the flow guide 7.

[0033] The material flow guide assembly 14 is installed on the upper support plate 1 and is responsible for guiding the molten material to flow into the key part of the mold cavity; the ring support 141 and the flow guide pipe group 142 work together to ensure that the material can enter the mold smoothly and uniformly, thereby improving the molding quality and production efficiency of the product.

[0034] The ring support 141 is usually located at the top of the material flow guide assembly 14 to support and fix the flow guide pipe group 142 and provide a stable inlet area so that the molten material can flow smoothly into the subsequent pipe.

[0035] The flow guide pipe group 142 is a channel system connecting the ring support 141 and the mold cavity, and the flow guide pipe group 142 efficiently transports the molten material from the ring support 141 to the flow guide 7, and then to the cavity forming the connector.

[0036] Further, the upper support plate 1 is provided with an inverted conical hole member, which is correspondingly arranged with the flow guide pipe group 142. The upper support plate 1 is connected with the ring support 141 through fasteners.

[0037] The inverted conical hole member is arranged on the upper support plate 1, which optimizes the flow path of the material from the feed port to the flow guide pipe group 142. The shape of the inverted conical hole member helps to reduce the turbulence generated when the molten material flows in, so that the material can flow more smoothly into the flow guide pipe group 142.

[0038] Further, the lower bottom plate 4 is provided with support guide columns 10 at both ends, which are correspondingly arranged with the side support frames 3 and pass through the side support frames 3 to be connected with the holes of the middle support seat 2.

[0039] The support guide columns 10 provide accurate guidance and support in the vertical direction, ensuring long-term stable operation.

[0040] The support guide columns 10 and the side support frames 3 ensure the alignment accuracy of the mold during operation, preventing the mold from shifting or deforming due to lateral forces or asymmetric loads.

[0041] The support guide columns 10 pass through the side support frames 3 and extend to the middle support seat 2, and are connected through the holes on the middle support seat 2. This makes the support guide columns 10 guide the movement of various components along the predetermined path, improving the operation accuracy of the mold and increasing the overall rigidity of the system, reducing the influence of external vibration and impact on the molding process.

[0042] Further, the lower bottom plate 4 is provided with limit guide columns 11, which pass through the placement blocks 8.

[0043] The limit guide columns 11 are arranged on the lower bottom plate 4, and the upper ends of the limit guide columns 11 are correspondingly arranged with the grooves in the lower clamping seat 22 to support the intermediate molded connector. Moreover, the limit guide columns 11 are positioned and guided by passing through the holes on the placement blocks 8, ensuring the accurate movement of the placement blocks 8 during the closing and opening of the mold.

[0044] Further, the lower bottom plate 4 is also provided with auxiliary support columns 12, the upper ends of which are connected with the lower end protrusions of the flow guide members 7.

[0045] The auxiliary support columns 12 can effectively transfer and disperse the pressure from the flow guide members 7, preventing deformation or damage caused by uneven local stress, ensuring that the flow guide members 7 maintain a stable position and posture during the entire molding process, and ensuring accurate alignment between them.

[0046] Further, the lower bottom plate 4 is also provided with elastic support seats 13.

[0047] The elastic support seat 13 is arranged on the lower bottom plate 4, which can absorb and buffer the impact force and vibration from each part of the mold; secondly, it can also allow the mold to have a certain floating space during closing and opening, which helps to relieve the friction and wear caused by the slight unevenness or misalignment between the mold parts.

[0048] In use: the pre-processed pins 9 are inserted into the cavities between the blocks 8, and the other end of the pins 9 is inserted into the circular hole of the cavity between the blocks 8, ensuring that each pin 9 is accurately placed in place, and then the blocks 8 are placed into the cavity.

[0049] The flow guide 7 is placed in the lower inner mold 6, and then the lower inner mold 6 is placed into the lower holder 22, and the upper inner mold 5 and the upper holder 21 are also operated in the same way, then the upper inner mold 5 and the lower inner mold 6 are aligned by the connecting shaft, and the upper holder 21 and the holder 22 are aligned, at this time the upper support plate 1 is pressed down, the mold is closed, when the mold is closed, the support guide column 10 smoothly descends along the guide structure of the side support frame 3 until it is completely embedded in the hole of the middle support seat 2. It ensures the accurate alignment of all components and provides a stable environment for molding.

[0050] At this time, the molten material is injected through the inverted conical hole on the upper support plate 1. The material is first concentrated and accelerated through the tapered channel of the ring support 141 in the inverted conical hole, and then distributed to each flow guide group 142, and then the flow guide group 142 efficiently transports the material to the flow guide 7, and finally fills the cavity between the upper inner mold 5 and the lower inner mold 6, fills the cavity at the pin 9, thereby completing the production of the connector, and when the preset time is reached, cooling and solidification are performed, the mold is opened, and each part is gradually removed to take out the workpiece.

[0051] Although the embodiments of the present application have been shown and described, it can be understood by those of ordinary skill in the art that various changes, modifications, replacements and variations can be made to the embodiments without departing from the principles and spirits of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
