DETAILED DESCRIPTION
[0028] The injection mold of the automobile electric drive filter support comprises an upper mold 21 and a lower mold 4 (see the attached drawings of the specification Figure 1 and 2 ).
[0029] The lower mold 4 is provided with a shaping sink 5; one side of the shaping sink 5 is slidingly provided with a shaping slider 6 (see the attached drawings of the specification Figure 6 ).
[0030] The shaping slider 6 has a block structure with a cross-section in the shape of the letter “Z”; one end of the shaping slider 6 is provided with a T-shaped notch 14; both sides of the shaping slider 6 are provided with guide rails 17 (see the attached drawings of the specification Figure 9 ). When assembling, the external components can drive the shaping slider 6 to slide back and forth through the T-shaped notch 14.
[0031] The other end of the shaping slider 6 is provided with a shaping plate 15; one side of the shaping plate 15 is provided with a shaping protrusion 16 (see the attached drawings of the specification Figure 9 ).
[0032] The shaping sink 5 is provided with multiple shaping pieces 8, sleeve positioning pins 9, and plate positioning pins 10 (see the attached drawings of the specification Figure 7 ). The bottom of the shaping sink 5 is provided with multiple positioning slots 7 (see the attached drawings of the specification Figure 8 ); the purpose of the positioning slots 7 is to enable the claws 3 on the metal plate 2 to be inserted into the corresponding positioning slots 7 after the metal plate 2 is assembled inside the lower mold 4 through the plate positioning pins 10 during injection molding. In this way, the metal plate 2 can be double-positioned through the positioning slots 7 and the plate positioning pins 10 when it is installed inside the lower mold 4, thereby reducing the risk of force deviation of the metal plate 2.
[0033] The four corners of the lower mold 4 are provided with positioning grooves 12; the four corners of the upper mold 21 are provided with positioning protrusions 13 (see the attached drawings of the specification Figure 6 and 10 ).
[0034] The positioning recess 12 and the positioning protrusion 13 are arranged to avoid the upper mold 21 and the lower mold 4 from deviating from the closed position during the closing process of the upper mold 21 and the lower mold 4.
[0035] The upper mold 21 is provided with a plurality of shaping protrusions 20 (see the accompanying drawings) Figure 10 and 11 The upper mold 21 is provided with a plurality of injection holes 11 (see the accompanying drawings) Figure 3 and 4 During operation, the two groups of metal plate pieces 2 are installed in the lower mold 4 through the plate positioning pins 10; the injection holes 11 correspond to the gaps between the two groups of metal plate pieces 2. The injection holes 11 are arranged to enable the plastic melt to flow into the two groups of metal plate pieces 2 through the injection holes 11 during injection, so that the metal plate pieces 2 only have the tendency to separate from each other when they are subjected to the thrust of the plastic melt, thereby solving the problem of low qualification rate caused by the two groups of metal plate pieces 2 easily closing to each other in the prior art injection method.
[0036] The lower mold 4 is provided with a plurality of demolding pins 19 which are slidably installed through the guide sliding cylinders 18. After the injection is completed, the demolding pins 19 can push the completed workpiece out of the lower mold 4 to complete the demolding work.
[0037] During operation of the injection mold for the automobile electric drive filter support, the metal plate pieces 2 are assembled on the lower mold 4 through the plate positioning pins 10, the metal ring 1 is assembled on the corresponding sleeve positioning pins 9, and then the upper mold 21, the lower mold 4 and the shaping sliding block 6 are closed; the shaping sink 5 on the lower mold 4 and the upper mold 21 form an injection cavity; then the plastic melt can be injected into the injection cavity through the injection holes 11 to complete the injection work; after the injection is completed, the upper mold 21 and the lower mold 4 are separated; the shaping sliding block 6 is reset. The demolding pins 19 can push the completed workpiece out of the lower mold 4 to complete the demolding work. At this time, the injection mold for the automobile electric drive filter support has completed the injection work of the automobile electric drive filter support, and the injection mold can enter the next working cycle.
[0038] The injection mold for the automobile electric drive filter support is compact in structure and ingenious in design, solves the problem of low qualification rate existing in the prior art production method of the automobile electric drive filter support by double positioning of the metal plate pieces 2 and injection of the plastic melt between the metal plate pieces 2, and is particularly suitable for the production of the automobile electric drive filter support.
