[0022] The present invention will now be described in further detail with reference to the accompanying drawings.

[0023] Please refer to the following: Figures 1 to 9 To achieve the above objectives, this utility model provides the following technical solution:

[0024] An injection mold for an in-vehicle wiring harness bracket includes a fixed mold assembly 1 and a moving mold assembly 2, wherein the moving mold assembly 2 is disposed on the upper end of the fixed mold assembly 1, and the moving mold assembly 2 and the fixed mold assembly 1 are tightly fitted together to form a sealed structure; the fixed mold assembly 1 includes a base plate 101, wherein a lower mold base 102 is provided above the base plate 101; a first receiving cavity 103 is provided at the upper end of the lower mold base 102, wherein a lower mold core 104 is provided in the first receiving cavity 103; a plurality of lower forming grooves 3 are provided at the upper end of the lower mold core 104, wherein a through-hole is provided in the lower forming groove 3.

[0025] The moving mold assembly 2 includes an injection molding main plate 201, wherein an upper mold base 202 is provided below the injection molding main plate 201; a second receiving cavity 203 is provided at the lower end of the upper mold base 202, wherein an upper mold core 204 is provided in the second receiving cavity 203; a plurality of upper forming grooves 9 are provided at the lower end of the upper mold core 204, wherein the upper forming grooves 9 are adapted to the lower forming grooves 3 provided at the upper end of the lower mold core 104, and the lower forming grooves 3 and the upper forming grooves 9 are closed to form a sealed forming cavity; a second through hole 10 is provided in the upper forming groove 9, penetrating the upper mold core 204, wherein a second through hole 10 is provided in the second through hole 10. An upper insert rod 11 is provided, and the lower end of the upper insert rod 11 is at the same height as the lower end face of the second through hole 10. A second core groove 12 is provided at the lower end of the upper insert rod 11, and one side of the second core groove 12 is connected to the upper molding groove 9. A second movable plate 13 is provided below the injection molding main plate 201, and a second lifting cylinder (not shown in the figure) is provided between the second movable plate 13 and the injection molding main plate 201. Several second push rods 14 are provided below the second movable plate 13, and the second push rods 14 correspond one-to-one with the upper insert rods 11, and the lower end of the second push rods 14 is fixedly connected to the upper end of the upper insert rod 11.

[0026] Injection molding process:

[0027] In the mold-closed state, the upper molding groove 9 and the lower molding groove 3 form a sealed molding cavity, and molten plastic is injected into this cavity through the injection molding machine; after the plastic cools and solidifies, it forms the preliminary shape of the wire harness bracket;

[0028] Demolding process:

[0029] The moving mold assembly 2 and the fixed mold assembly 1 are separated. The first lifting cylinder and the second lifting cylinder respectively drive the first movable plate 7 and the second movable plate 13 to rise, which drives the first ejector rod 8 and the second ejector rod 14 to eject the product, so that the wire harness bracket is removed from the mold.

[0030] Product removal and mold reset:

[0031] After the wire harness bracket is removed, the first and second lifting cylinders are reset, the first movable plate 7 and the second movable plate 13 descend, and the first push rod 8 and the second push rod 14 are also reset, ready for the next injection molding.

[0032] This mold structure enables efficient and precise production of in-vehicle wiring harness brackets through a precise mold closing and demolding process.

[0033] Please refer to the following: Figures 2 to 4 As one embodiment of the present utility model, the first movable plate 7 is provided with first limiting posts 15 at the four corners, wherein the outer wall of the first limiting post 15 is fitted with a first buffer sleeve 16; the lower mold base 102 is provided with first limiting holes 17 corresponding to the first limiting posts 15, wherein the first limiting post 15 passes through the first limiting hole 17, and the lower diameter of the first limiting hole 17 is equivalent to the outer diameter of the first buffer sleeve 16.

[0034] In the above-described scheme, the first movable plate 7 is designed with first limiting posts 15 at its four corners. These limiting posts play a precise positioning role during mold closing and opening. The lower mold base 102 is correspondingly provided with first limiting holes 17 that match the first limiting posts 15 one by one, ensuring that the first movable plate 7 can move smoothly along the predetermined trajectory during lifting and lowering, avoiding deviation or shaking. The outer wall of the first limiting post 15 is fitted with a first buffer sleeve 16. This design aims to reduce the direct impact of the first movable plate 7 on the lower mold base 102 during lifting and lowering. When the first movable plate 7 rises or falls under the drive of the first lifting cylinder, the first buffer sleeve 16 will first contact the edge of the first limiting hole 17, absorbing the impact force through its elastic deformation, thereby protecting the mold components from impact. Damage is prevented; the diameter of the hole below the first limiting hole 17 is precisely designed to be equivalent to the outer diameter of the first buffer sleeve 16 to ensure a tight fit between the two. This tight fit not only improves the positioning accuracy of the mold, but also ensures that the first buffer sleeve 16 can effectively function when subjected to impact, preventing the mold components from deforming or being damaged due to excessive impact force; through the precise design and fit of the first limiting post 15, the first buffer sleeve 16 and the first limiting hole 17, the mold can maintain a high degree of stability during the injection molding process; at the same time, the first buffer sleeve 16 is made of elastic material, which can withstand multiple impacts and compressions, ensuring the durability and long-term reliability of the mold, and providing a strong guarantee for the injection molding of the in-vehicle wiring harness bracket.

[0035] Please refer to the following: Figures 6 to 8 As one embodiment of the present utility model, the second movable plate 13 is provided with second limiting posts 18 at the four corners, wherein the outer wall of the second limiting post 18 is fitted with a second buffer sleeve 19; the upper mold base 202 is provided with second limiting holes 20 corresponding to the second limiting posts 18, wherein the second limiting post 18 passes through the second limiting hole 20, and the upper diameter of the second limiting hole 20 is equivalent to the outer diameter of the second buffer sleeve 19.

[0036] In the above-described scheme, the second movable plate 13 is equipped with second limiting posts 18 at its four corners. These limiting posts play a precise positioning and guiding role during the mold closing and opening process. The upper mold base 202 is provided with second limiting holes 20 corresponding to the second limiting posts 18 one by one, ensuring that the second movable plate 13 can move smoothly along the axis of the second limiting posts 18 during lifting and lowering, avoiding offset or shaking, thereby ensuring the mold closing accuracy and the dimensional accuracy of the injection molded product. The outer wall of the second limiting posts 18 is fitted with a second buffer sleeve 19. This design aims to reduce the direct impact of the second movable plate 13 on the upper mold base 202 during lifting and lowering. When the second movable plate 13 rises or falls under the drive of the second lifting cylinder, the second buffer sleeve 19 will first contact the edge of the second limiting hole 20, and absorb the impact force through its elastic deformation, thereby protecting the mold components from damage. This buffering effect also helps to reduce the wear of the mold during long-term use and extend the service life of the mold. The diameter of the hole above the second limiting hole 20 is precisely designed to be equivalent to the outer diameter of the second buffer sleeve 19 to ensure a tight fit between the two. This tight fit not only improves the positioning accuracy of the mold, but also enhances the stability of the mold during the injection molding process. When the mold is subjected to injection pressure or other external forces, the tight fit between the second limiting post 18 and the second buffer sleeve 19 can prevent the mold components from shifting or deforming, thereby ensuring the quality of the injection molded product. The second buffer sleeve 19 is usually made of elastic material, which has good wear resistance and impact resistance. During the long-term use of the mold, the second buffer sleeve 19 can withstand multiple impacts and compressions, maintaining its elasticity and buffering performance, thereby ensuring the durability and reliability of the mold and providing strong support and guarantee for the injection molding of the in-vehicle wiring harness bracket.

[0037] Please refer to the following: Figure 2 , Figure 6 As one embodiment of the present utility model, the upper mold base 202 is provided with guide posts 21 at the four corners of the lower end, and the lower mold base 102 is provided with positioning holes adapted to the guide posts 21 at the four corners of the upper end, and guide sleeves 22 are installed in the positioning holes.

[0038] In the above-described scheme, guide pillars 21 are installed at the four corners of the lower end of the upper mold base 202, while the upper end of the lower mold base 102 is correspondingly provided with positioning holes adapted to the guide pillars 21. When the mold is closed or opened, the guide pillars 21 slide along the guide sleeves 22 in the positioning holes, ensuring that the relative movement between the upper mold base 202 and the lower mold base 102 remains accurate and stable. This guiding effect helps to prevent the mold from shifting or shaking during the mold closing or opening process, thereby ensuring the dimensional accuracy and appearance quality of the injection molded product. The fit between the guide pillars 21 and the guide sleeves 22 is usually precise, and the gap between them is controlled within a very small range. This precise fit helps to reduce... The friction and wear between the guide post 21 and the guide sleeve 22 extend the service life of the mold. At the same time, the guide sleeve 22 is usually made of a material with good wear resistance, such as hard alloy or stainless steel, to further improve its durability. The cooperation between the guide post 21, the positioning hole and the guide sleeve 22 not only plays a guiding role, but also ensures the accurate positioning of the mold when the mold is closed. When the upper mold base 202 descends and contacts the lower mold base 102, the guide post 21 will first enter the positioning hole and slide along the guide sleeve 22 until the upper mold base 202 and the lower mold base 102 are completely fitted. This positioning method helps to ensure that the mold always maintains the correct position during the injection process and avoids injection defects caused by inaccurate mold positioning.

[0039] In summary, the guide pillars 21 at the four corners of the lower end of the upper mold base 202, together with the positioning holes at the four corners of the upper end of the lower mold base 102 and the guide sleeves 22 inside them, constitute an efficient and stable guiding and positioning system. This system not only ensures the precise positioning and stable movement of the mold during the injection molding process, but also improves production efficiency, reduces production costs, and protects other parts of the mold from damage.

[0040] Please refer to the following: Figure 1 , Figure 5 and Figure 9 As one embodiment of this utility model, the upper end of the lower mold core 104 is provided with a flow channel 23, wherein the flow channel 23 is provided with multiple channels and is respectively connected to the lower forming groove 3 provided on the upper end surface of the lower mold core 104; the injection main plate 201 is provided with an injection port 25 in the middle, wherein the upper mold core 204 is provided with an injection through hole 26 in the middle; the upper end of the injection through hole 26 is connected to the injection port 25 through a pipe, wherein the lower end of the injection through hole 26 is connected to the flow channel 23.

[0041] In the above-described scheme, the upper end of the lower mold core 104 is designed with flow channels 23, which are connected to the lower molding groove 3. The function of the flow channels 23 is to guide the molten plastic from the injection channel into the lower molding groove 3 and fill the mold. The injection main plate 201 is located at the center of the mold and has an injection port 25. The injection port 25 is the entrance for the molten plastic to enter the mold. The middle of the upper mold core 204 is designed with an injection through hole 26. This hole penetrates the upper mold core 204, and its upper end is connected to the injection port 25 through a pipe, while its lower end is connected to the flow channels 23. The function of the injection through hole 26 is to serve as a transmission channel for the molten plastic, introducing the plastic from the injection port 25 into the flow channels 23, and injecting it into the cavity formed by the lower molding groove 3 and the upper molding groove 9 through the flow channels 23.

[0042] Injection molding process

[0043] Driven by the injection molding machine, molten plastic is injected into the injection port 25 on the injection main board 201; the molten plastic flows downward through the injection through hole 26 and is diverted into the runner 23; in the runner 23, the plastic flows downward and enters the cavity composed of the lower molding groove 3 and the upper molding groove 9; as the molten plastic is continuously injected, the upper molding groove 9 and the lower molding groove 3 are gradually filled with plastic; when the mold cavity is completely filled, the injection molding machine stops injecting plastic and enters the holding pressure stage to ensure that the plastic in the mold cavity can be fully cooled and solidified; after the plastic has been completely cooled and solidified, the mold will open, the upper mold core 204 and the lower mold core 104 will separate, and the injection molded product will be ejected from the mold cavity; the design of the runner system allows the molten plastic to enter the mold cavity quickly and evenly, thereby improving the injection efficiency; through the reasonable layout and size design of the runner 23, the retention and waste of molten plastic in the runner 23 can be reduced; the smooth injection channel helps to reduce pressure and temperature fluctuations during the injection process, thereby improving the dimensional accuracy and appearance quality of the finished product.

[0044] In summary, the lower mold core 104, the upper mold core 204, the injection main plate 201, and the runner system between them together constitute an efficient and stable injection channel. This system not only ensures that the molten plastic can enter the mold cavity quickly and evenly, but also improves injection efficiency and finished product quality.

[0045] Please refer to the following: Figure 5 , Figure 9 As one embodiment of the present invention, the lower mold core 104 is provided with positioning grooves 27 at the four corners, and the upper mold core 204 is provided with positioning protrusions 28 at the four corners that are adapted to the positioning grooves 27.

[0046] In the above-described scheme, positioning grooves 27 are precisely cut at the four corners of the lower mold core 104 according to the specific size and shape requirements of the mold. These positioning grooves 27 usually have a certain depth and width to ensure that they can fit tightly with the positioning protrusions 28 of the upper mold core 204. Positioning protrusions 28 are designed at the four corners of the upper mold core 204 according to the size and shape of the positioning grooves 27 of the lower mold core 104. The size and shape of the positioning protrusions 28 need to be completely matched with the positioning grooves 27 to ensure that they can be accurately and stably inserted into the grooves during the mold closing process.

[0047] Before the injection molding machine prepares for the mold closing operation, the upper mold core 204 and the lower mold core 104 are in the open state. At this time, the positioning protrusion 28 and the positioning groove 27 are not in contact, ready for the subsequent mold closing operation. When the injection molding machine starts the mold closing operation, the upper mold core 204 gradually moves downward. As the upper mold core 204 descends, the positioning protrusion 28 gradually approaches the positioning groove 27. When the positioning protrusion 28 is fully inserted into the positioning groove 27, the relative position between the upper mold core 204 and the lower mold core 104 is precisely locked. The tight fit between the positioning protrusion 28 and the positioning groove 27 ensures the precise positioning of the upper mold core 204 and the lower mold core 104 during the mold closing process. This positioning mechanism helps prevent mold offset or wobbling during injection molding, thus ensuring the dimensional accuracy and appearance quality of the injection-molded product. During injection molding, the tight fit between the positioning protrusion 28 and the positioning groove 27 also helps maintain mold stability, which helps reduce pressure and temperature fluctuations during injection molding, further improving the quality of the finished product. The positioning groove 27 and positioning protrusion 28 design between the lower mold core 104 and the upper mold core 204 is an efficient and stable positioning mechanism. This mechanism not only ensures accurate positioning of the mold during injection molding but also improves mold stability and production efficiency, providing a strong guarantee for the quality of the injection-molded product.
