Description

Technical Field

[0001] The invention relates to the technical field of molds, and more specifically to a production mold for a wire harness fixing bracket. Background Art

[0002] After being subjected to long-term high temperature and vibration environment, automobile wiring harnesses are prone to deformation and fatigue, which will seriously affect the electrical conductivity of the wiring harnesses and even interfere with the signal of the engine wiring harnesses, resulting in malfunction. Therefore, the wiring harness fixing bracket, as a protective structure for the wiring harness, can restrain the wiring harness and play a role in shock absorption. Due to the limitations of the body sheet metal shape, the wiring harness must be arranged in the same direction as the sheet metal to be firmly positioned. Therefore, the layout of the automobile wiring harness fixing bracket needs to match the body sheet metal.

[0003] like Figure 1-2 As shown in the figure, it is a schematic diagram of the structure of the plastic part of the automobile wiring harness fixing bracket. The two ends of the plastic part are respectively the first end and the second end. From the first end to the second end, it is bent many times, and the angle of the bend closest to the first end is an obtuse angle, resulting in an obvious height difference between the first end and the second end of the plastic part. The first end is provided with a first claw-type clamping structure, a first clamping claw and a first internal reinforcing rib, and the second end is provided with a second claw-type clamping structure, a second clamping claw and a second internal reinforcing rib. The lateral direction of the first claw-type clamping structure is perpendicular to the length direction of the plastic part, and the lateral direction of the second claw-type clamping structure is parallel to the length direction of the plastic part. The first clamping claw and the second clamping claw are formed by arc-shaped extensions of the opening edges of the first end wire groove and the opening edges of the second end wire groove, respectively. Such a complex structure brings many difficulties to the mold design. Summary of the invention

[0058] Furthermore, in this embodiment, four reset rods 350 are fixedly mounted on the top plate 380 , the reset rods 350 pass through the movable template 310 , and a flat wire coil spring 360 is sleeved on the reset rods 350 , the upper end of the flat wire coil spring 360 abuts against the movable template 310 , and the lower end abuts against the top plate 380 .

[0059] Furthermore, the steps for using the mold in this embodiment are as follows:

[0060] First, the fixed mold assembly 200 and the movable mold assembly 300 are molded together, and molten liquid is injected into the mold cavity, and cooled to form the wiring harness fixing bracket plastic part 100. Then, the first oblique withdrawal mechanism 400 and the second oblique withdrawal mechanism 500 are activated, and the first core-pulling oil cylinder 420 drives the first oblique withdrawal slide 430 to move. Since the T-shaped block on the first oblique withdrawal rod 410 and the oblique wedge T-shaped groove on the first oblique withdrawal slide 430 slide in sliding cooperation, the horizontal movement of the first oblique withdrawal slide 430 is changed into the oblique core-pulling action of the first oblique withdrawal rod 410. Similarly, the second core-pulling oil cylinder 520 drives the second oblique withdrawal guide rod 530 to move, and the horizontal movement of the second oblique withdrawal guide rod 530 is changed into the oblique core-pulling action of the second oblique withdrawal guide rod 530.

[0061] Then, the mold is opened, and the movable mold assembly 300 moves away from the fixed mold assembly 200. During this process, the first oblique guide column 221 drives the first slider 321 to move, and the second oblique guide column 222 drives the second slider 322 to move synchronously, and the first slider 321 and the second slider 322 move away from each other. The third bent pin 223 drives the third slider 323 to move, the fourth oblique guide column 224 drives the fourth slider 324 to move, and the fifth oblique guide column 225 drives the fifth slider 325 to move synchronously, and the fourth slider 324 and the fifth slider 325 move away from each other. The first bent pin 230 drives the third oblique pull-out slide 331 to move horizontally, and the third oblique pull-out slide 331 drives the third oblique pull-out rod 332 to perform an oblique core pulling action. At the same time, the second bent pin 240 drives the fourth oblique pull-out slide 341 to move horizontally, and the fourth oblique pull-out slide 341 drives the fourth oblique pull-out rod 342 to perform an oblique core pulling action.

[0062] Finally, the ejector plate 380 ejects the plastic part 100 through the ejector pin 370, so that the plastic part 100 is separated from the movable mold core 320. After the plastic part 100 is taken out, the ejector plate 380 retreats and the mold is closed. During the mold closing process, the first slider 321, the second slider 322, the third slider 323, the fourth slider 324 and the fifth slider 325 move in the opposite direction compared with the previous step, and the piston rod of the first core-pulling cylinder 420 extends to drive the first oblique pull rod 410 to move; similarly, the piston rod of the second core-pulling cylinder 520 extends to drive the second oblique pull rod 510 to move. The molten material is injected into the cavity and cooled to form the wiring harness fixing bracket plastic part 100.
