Description

Technical Field

[0001] This utility model relates to the field of injection molds, specifically an injection mold for processing automotive wiring harness accessories. Background Technology

[0002] Automotive wiring harness accessories are mainly used for the connection and fixation of automotive electrical systems. They include various connectors, terminals, plugs, sockets, brackets, and other parts. These accessories are used to connect cables inside and outside the vehicle to ensure the stable operation of the automotive electrical system. With the progress of automotive electrification and intelligence, the design and processing precision requirements for wiring harness accessories are becoming increasingly higher. Injection molds play a key role in the production of automotive wiring harness accessories. The mold heats and melts the plastic raw material and injects it into the mold cavity to form the required part shape. The precision of the injection mold directly affects the size, strength, and surface quality of the automotive wiring harness accessories.

[0003] Currently, automotive wiring harness accessories have relatively complex structures, often featuring special features such as undercuts and deep cavities on their surfaces. During the injection molding process, once the automotive wiring harness accessory is formed, it needs to be ejected from the lower mold to achieve demolding. However, due to the special structures such as undercuts and deep cavities, the accessory is prone to close contact or hooking with the cavity of the lower mold during ejection. This may prevent the finished automotive wiring harness accessory from separating smoothly from the cavity of the lower mold, thereby increasing the resistance during demolding. Utility Model Content

[0004] The purpose of this utility model is to provide an injection mold for processing automotive wiring harness accessories, so as to solve the problems mentioned in the background art.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] An injection mold for processing automotive wiring harness accessories includes an upper mold and a lower mold. A support base is fixedly installed at the lower end of the lower mold. Cavities are formed inside the upper end of the lower mold. Inserts are slidably fitted inside the cavities on one side. A forming groove is formed at one end of each of the inserts. Sliding components for moving the inserts are provided on both sides of the lower mold.

[0007] Preferably, both sets of sliding components include a fixed plate, one end of which is fixedly installed on one side of the lower mold. Sliding blocks are slidably connected to both ends of the interior of the fixed plate. The upper ends of the two sliding blocks are fixedly connected to the lower end of the insert near the center. A sliding groove is provided on one side of the cavity of the lower mold. The sliding groove and the sliding trajectory of the fixed plate are aligned on the same horizontal plane, and the sliding blocks are slidably connected inside the sliding groove.

[0008] Preferably, each of the two sliding blocks is rotatably connected to a lead screw, and the two lead screws are rotatably sleeved inside the sliding track of the fixed plate. A bearing sleeve is rotatably sleeved at one end of each of the two lead screws, and the two bearing sleeves are fixedly sleeved inside one side of the fixed plate.

[0009] Preferably, one end of each of the two lead screws is fixedly connected to a gear, and the outer sides of each of the two gears are meshed with a spur bar.

[0010] Preferably, a telescopic push rod is fixedly installed at one end of the spur gear, a hydraulic cylinder is slidably sleeved at one end of the telescopic push rod, a connecting plate is fixedly installed at one end of the hydraulic cylinder, and a support plate is fixedly installed at one end of the connecting plate.

[0011] Preferably, the support plate has guide grooves on one side and the upper end, and movable rods are slidably connected inside the guide grooves. The movable rods are fixedly connected to the upper end and one side of the straight toothed rod, and the lower end of one side of the support plate is fixedly installed on the upper end of the fixed plate.

[0012] The beneficial effects of this utility model are:

[0013] 1. This utility model uses a sliding component. The corresponding position of the molding groove of the insert has an undercut and a deep cavity. It is necessary to drive the insert to move slightly backward to separate it from the finished automotive wiring harness accessory. This reduces the resistance generated during demolding and helps to generate less friction between the automotive wiring harness accessory molded part and the mold, ensuring smooth demolding. It avoids the automotive wiring harness accessory from being tightly attached and hooked to the cavity of the lower mold during the ejection process, which would prevent the finished automotive wiring harness accessory from being unable to separate smoothly from the cavity of the lower mold, thereby reducing the resistance during demolding.

[0014] 2. This utility model ensures the linear motion stability of the insert during the process by synchronously sliding the movable rod of the straight toothed rod in the guide groove, thus avoiding deviation or jamming. Attached Figure Description

[0024] Please refer to Figure 1 As shown, an injection mold for processing automotive wiring harness accessories includes an upper mold 1 and a lower mold 2. A support base 5 is fixedly installed at the lower end of the lower mold 2. A cavity 3 is opened inside the upper end of the lower mold 2. An insert 4 is slidably fitted inside the cavity 3 on one side. A forming groove 41 is opened at one end of the insert 4. Sliding components 6 for moving the insert 4 are provided on both sides of the lower mold 2.

[0025] In a specific embodiment, before processing, according to the size requirements of the wire harness accessories, the sliding components 6 on both sides of the lower mold 2 drive the insert 4 to slide in the cavity 3, and the upper mold 1 moves downward to precisely fit with the lower mold 2. At this time, the inner surface of the upper mold 1, the cavity 3 of the lower mold 2, and the forming groove 41 of the insert 4 together form a closed forming cavity 3. The shape of this cavity is the final formation of the automotive wire harness accessories. The forming groove 41 has undercuts and deep cavities at the corresponding positions. The sliding components 6 need to drive the insert 4 to move back slightly in the opposite direction to separate it from the finished product and reduce the demolding resistance.

[0026] Please refer to Figures 1 to 6As shown, as a technical optimization of this utility model, both sets of sliding components 6 include a fixed plate 61. One end of the fixed plate 61 is fixedly installed on one side of the lower mold 2. Sliding blocks 62 are slidably connected to both ends of the fixed plate 61. The upper ends of the two sliding blocks 62 are fixedly connected to the lower end of the insert 4 near the center. A sliding groove 63 is provided on one side of the cavity 3 of the lower mold 2. The sliding groove 63 and the sliding trajectory of the fixed plate 61 are aligned on the same horizontal plane. The sliding blocks 62 are slidably connected inside the sliding groove 63. A lead screw 64 is rotatably connected inside the two sliding blocks 62. The two lead screws 64 are rotatably sleeved inside the sliding trajectory of the fixed plate 61. A bearing sleeve 65 is rotatably sleeved on one end of the outer side of the two lead screws 64. The two bearing sleeves 65 are fixedly sleeved inside one side of the fixed plate 61.

[0027] Furthermore, a gear 66 is fixedly connected to one end of each of the two lead screws 64, and a spur gear 67 is meshed with the outer side of each of the two gears 66. A telescopic push rod 613 is fixedly installed at one end of the spur gear 67, and a hydraulic cylinder 68 is slidably sleeved at one end of the telescopic push rod 613. A connecting plate 69 is fixedly installed at one end of the hydraulic cylinder 68, and a support plate 610 is fixedly installed at one end of the connecting plate 69. Guide grooves 612 are opened inside one side and the upper end of the support plate 610. Movable rods 611 are slidably connected inside the guide grooves 612. Movable rods 611 are fixedly connected to the upper end and one side of the spur gear 67. The lower side of the support plate 610 is fixedly installed on the upper end of the fixed plate 61.

[0028] In a specific embodiment, when the automotive wiring harness parts are formed inside the cavity 3 of the current mold 2, the corresponding position of the forming groove 41 has an undercut and a deep cavity. The sliding component 6 needs to drive the insert 4 to move slightly backward to separate from the finished product and reduce the demolding resistance. The hydraulic cylinder 68 pushes the spur gear 67 to move towards the fixed plate 61 through the telescopic push rod 613. The spur gear 67 drives the gear 66 to rotate. The gear 66 drives the lead screw 64 to rotate, so that the sliding block 62 slides along the fixed plate 61 and the sliding groove 63. The sliding block 62 drives the insert 4 to move out of the cavity 3. The movable rod 611 of the spur gear 67 slides synchronously in the guide groove 612 to ensure the stability of the linear motion of the spur gear 67 and avoid deviation during the transmission process.

[0029] In use, the sliding components 6 on both sides of the lower mold 2 drive the insert 4 to slide within the cavity 3. The upper mold 1 moves downward and precisely fits with the lower mold 2. At this time, the inner surface of the upper mold 1, the cavity 3 of the lower mold 2, and the forming groove 41 of the insert 4 together form a closed forming cavity 3. When the automotive wiring harness parts are formed inside the cavity 3 of the lower mold 2, the corresponding position of the forming groove 41 has an undercut and a deep cavity. The sliding components 6 need to drive the insert 4 to move slightly backward to separate it from the finished product and reduce the demolding resistance. The hydraulic cylinder 68 pushes the spur gear 67 towards the fixed plate 61 through the telescopic push rod 613. The spur gear 67 drives the gear 66 to rotate. The gear 66 drives the lead screw 64 to rotate, causing the sliding block 62 to slide along the fixed plate 61 and the sliding groove 63. The sliding block 62 drives the insert 4 to move out of the cavity 3. The movable rod 611 of the spur gear 67 slides synchronously in the guide groove 612 to ensure the stability of the linear motion of the spur gear 67 and avoid deviation during transmission.
