Description

Technical Field

[0001] The utility model relates to the field of wire harness manufacturing, in particular to an injection mold for a pipeline joint. Background Art

[0002] After the battery cells of the automotive wiring harness are connected to the battery cells of the pipeline joint by resistance welding, it is necessary to wrap the plastic shell at the pipeline joint and the battery cell connection through the injection molding process to form a whole with the automotive wiring harness and the pipeline joint. The plastic shell wraps the battery cell to protect it from short circuit or leakage, and it can also enhance the structural strength of the connection between the automotive wiring harness and the pipeline joint to avoid breakage at the connection.

[0003] The injection molding production process is as follows: first, the automobile wiring harness and the pipeline connector are placed between the upper and lower molds of the injection mold, and then the upper mold is moved toward the lower mold. After closing, high-temperature liquid plastic is injected into the mold cavity of the upper and lower molds. After the liquid plastic solidifies in the mold cavity, the injection molded shell of the pipeline connector is completed, the upper mold is lifted upward, and the pipeline connector is taken out of the mold cavity. The technical staff of our company found in production that the automobile wiring harness connected to the pipeline connector is usually long and has a certain weight, and the pipeline connector is placed between the upper and lower molds without any fixing measures. Under the influence of the weight of the automobile wiring harness, the pipeline connector may be offset or even detached from the upper and lower molds, seriously affecting the quality and yield of the injection molding production. In order to fully fill the liquid plastic in the mold cavity, the injection mold usually has a high temperature of 200-400°C to ensure the fluidity of the liquid plastic. Even if the worker holds the wiring harness for fixing, in order to prevent burns, the holding position cannot be close to the injection mold, and the fixing effect is very limited. If it is too close to the injection mold, there is also a safety hazard of being burned by the injection mold or squeezed by the upper and lower molds. Utility Model Content

[0026] See also Figure 1-Figure 4 A pipeline joint injection mold, comprising a mold body 1 and a joint fixing module 2, the mold body 1 comprising an upper mold 11 and a lower mold 12, the upper mold 11 is movably connected to the upper part of the lower mold 12, the joint fixing module 2 comprises a joint bracket 21 and a sliding rail 22, the sliding rail 22 is vertically fixedly connected to the side of the lower mold 12, the joint bracket 21 comprises a bracket seat 211 and a bracket cover 212, the lower side of the bracket seat 211 is slidably connected to the sliding rail 22, so that the joint fixing module 2 can slide along the sliding rail 22 to move away from or approach the mold body 1, the upper side surface of the bracket seat 211 is rotatably connected to the bracket cover 212, the rotation direction of the bracket cover 212 is perpendicular to the arrangement direction of the sliding rail 22, and the upper side surface of the bracket seat 211 is provided with a harness groove 21 3. The harness groove 213 is arranged perpendicular to the side of the mold body 1. After the bracket cover 212 is flipped open, the harness groove 213 can accommodate the automobile harness connected to the pipeline connector. After the automobile harness is placed in the harness groove 213, the connector fixing module 2 is pushed to slide toward the mold body 1. When the connector fixing module 2 is close to the mold body 1, the pipeline connector can just enter between the lower mold 12 and the upper mold 11. When the lower mold 12 is moved downward for injection molding, because the bracket cover 212 and the bracket seat 211 are pressed and fixed, the pipeline connector will no longer move relative to the upper mold 11 and the lower mold 12 due to the weight of the harness, thereby improving the injection molding production quality and yield rate of the pipeline connector housing, and there is no need for workers to hold the harness, thereby avoiding safety accidents such as workers being scalded or squeezed by the mold.

[0027] In order to ensure that the pipeline joint can be fixed between the upper mold 11 and the lower mold 12, see Figure 1 A lower joint groove 13 is provided on the upper surface of the lower mold 12 facing the upper mold 11, and an upper joint groove 14 is provided on the lower surface of the upper mold 11 facing the lower mold 12. The shapes of the lower joint groove 13 and the upper joint groove 14 match the shape of the pipeline joint, and the upper joint groove 14 and the lower joint groove 13 are both connected with the surfaces of the corresponding upper mold 11 and the lower mold 12.

[0028] Furthermore, in order to enable the pipeline joint fixed by the joint fixing module 2 to enter between the upper mold 11 and the lower mold 12, the height of the bracket seat 211 matches the height of the lower mold 12, and the height of the wiring harness groove 213 matches the height of the lower joint groove 13, so that when the joint bracket 21 clamps the pipeline joint and moves toward the lower mold 12, the pipeline joint can enter the upper joint groove 14 and the lower joint groove 13 of the upper mold 11 and the lower mold 12.

[0029] In order to prevent the joint bracket 21 from sliding off the sliding rail 22, see Figure 1 and Figure 4 The end of the sliding rail 22 away from the mold body 1 is vertically fixedly connected to a limit baffle 23, and the size of the limit baffle 23 is larger than the cross-sectional size of the sliding rail 22.

The arrangement position of the second magnet 214 corresponds to the first magnet 231, and the polarities of the opposite surfaces of the first magnet 231 and the second magnet 214 are opposite. Under the suction force of oppositely charged magnets, when the bracket seat 211 is close to the limit baffle 23, the bracket seat 211 can be adsorbed on the limit baffle 23 to complete the fixation of the connector bracket 21.

[0031] In order to ensure the stability of the bracket cover 212 in fixing the automobile wiring harness in the wiring harness slot 213 and prevent the automobile wiring harness from deviating and shaking in the wiring harness slot 213, see Figure 2A third magnet 215 is provided on the lower surface of the bracket cover 212, and a fourth magnet 216 is provided on the surface of the bracket seat 211 facing the bracket cover 212. The arrangement position of the fourth magnet 216 corresponds to the third magnet 215, and the polarities of the opposite surfaces of the third magnet 215 and the fourth magnet 216 are opposite. Under the suction force of oppositely charged magnets, after the bracket cover 212 is flipped and covered on the bracket seat 211, the bracket cover 212 can be adsorbed on the bracket seat 211 to prevent the bracket cover 212 from being accidentally opened, causing the automobile wiring harness in the wiring harness slot 213 to deviate or detach therefrom.

[0032] Furthermore, in order to further enhance the fixing ability of the automobile wiring harness in the wiring harness groove 213 and prevent the automobile wiring harness from sliding back and forth in the wiring harness groove 213, a plurality of raised limit strips 217 are provided in the wiring harness groove 213, and the limit strips 217 are arranged perpendicular to the length direction of the wiring harness groove 213. The provision of the plurality of limit strips 217 can increase the friction between the inner wall of the wiring harness groove 213 and the outer surface of the automobile wiring harness, thereby fixing the automobile wiring harness and preventing the automobile wiring harness from sliding back and forth in the wiring harness groove 213 and affecting the positioning of the pipeline joint between the upper mold 11 and the lower mold 12.

[0034] Furthermore, in order to fix the position of the joint bracket 21 after it is close to the mold body 1 and prevent the joint bracket 21 from sliding in the opposite direction, a fifth magnet 25 is provided on the surface of the thermal insulation pad 24 facing the lower mold 12, and a sixth magnet 15 is provided on the surface of the lower mold 12 facing the thermal insulation pad 24. The arrangement position of the fifth magnet 25 corresponds to that of the sixth magnet 15, and the polarities of the opposite surfaces of the fifth magnet 25 and the sixth magnet 15 are opposite. The fifth magnet 25 can absorb the sixth magnet 15 and fix the joint bracket 21 close to the surface of the mold body 1 for absorption.

[0035] In order to facilitate the operator to push the joint bracket 21 and flip the bracket cover 212, see Figure 2 A handle ring 26 is vertically fixed to the side surface of the bracket cover 212 away from the mold body 1. The worker can flip the bracket cover 212 through the handle ring 26, and can also push the joint bracket 21 to slide back and forth on the sliding rail 22 through the handle ring 26.
