- injection molding plastics In injection molding plastics.
- the sealed cable lead-out capacitor formed by injection molding characterized in that: The upper end of the injection molding plastic is injection molded to form a lead-out tube through which the lead cable is passed.
- the sealed cable lead-out capacitor formed by the injection molding is characterized in that: the lead end cover has a peripheral ring, and the peripheral ring surrounds the welding defect.
- An injection molding method for forming a sealed cable lead-out capacitor formed by injection molding as described above characterized in that: it uses a special injection mold; the special injection mold is composed of upper and lower molds, and the cavity is sequentially from bottom to top The capacitor body slot, the peripheral ring positioning slot and the cable line positioning slot are disposed, and the top block is disposed under the capacitor body slot; the specific steps are:
- the capacitor body is placed in the capacitor body slot of the injection mold, and the lead cable is placed in the cable positioning groove, and the outer ring on the end cover is placed in the outer ring groove;
- top block on the injection mold is placed against the bottom of the capacitor body to fix the capacitor body to prevent displacement of the capacitor body during the injection molding process.
- the top block is placed against the bottom of the capacitor body, resulting in the capacitor body upper edge and the capacitor body on the injection mold.
- the upper edge of the groove is closely matched, and the upper space of the capacitor body forms an injection cavity;
- the special injection mold further comprises an extraction tube injection groove, which is disposed between the peripheral ring positioning groove and the cable line positioning groove, and is used for injection molding of an injection molding structure in which an extraction pipe is to be provided.
- the advantages of the present invention are: 1. Compared with the existing products, the invention does not need to process and pull out the positioning sleeve, and therefore, it is not necessary to add a cable to pass out and locate the process step of pulling out the positioning sleeve in the assembly process.
- the invention does not need to fill the epoxy resin, and replaces the insulation and positioning function of the epoxy resin by the integral injection molding, which not only simplifies the operation, but also reduces the material cost.
