Embodiment Construction

[0029] The present invention will be further described below in conjunction with accompanying drawing.

[0030] Such as figure 1 and figure 2 As shown, the present invention provides a combined stator preheating device for a plastic-encapsulated motor, which mainly includes: a stator heating core 1 , a combined core base plate 2 , a heat shield 3 , a support frame 4 and a foot 5 .

[0031] Wherein, the composite mold core bottom plate 2 can be formed as one board or a plurality of detachable boards, and when the composite mold core bottom plate 2 has multiple boards, they can be assembled on the same plane.

[0032] The shape and size of the stator heating mold core 1 is basically the same as that of the injection mold core on the injection mold for injecting the stator. The stator heating mold cores 1 are approximately cylindrical, and there are a plurality of them, which are arranged on the combined mold core bottom plate 2 . The stator heating cores 1 can be arranged in...

Abstract

The invention provides a preheating device and a preheating method for a combined stator of a plastic package motor. The device comprises a combined mould core bottom plate, and a stator heating mouldcore, wherein the stator heating mould core and an injection mould core on an injection mould for performing injection moulding on the stator are consistent in shape and dimension; and the stator heating mould core is arranged on the combined mould core bottom plate. The method comprises the following steps: (1) sleeving the stator onto the stator heating mould core; (2) heating the stator heating mould core, thereby preheating the stator; and (3) sleeving the pre-heated stator on the injection mould core of the injection mould, and performing injection moulding. According to the preheating device disclosed by the invention, the stator of the plastic package motor is creatively preheated, the preheated stator and the injection mould core are loosened, and staff operation is convenient, sothat the problem that winding damages due to the fact that the stator cannot be placed in and external force knock is needed is avoided; the preheated stator can effectively solve poor plastic package material mobility due to stator heat absorption in an injection moulding process, and can effectively solve the problem that badness is caused as the winding is damaged in an injection moulding process if impact force on a winding is increased.

Description

technical field [0001] The invention relates to the field of plastic-encapsulated motors, in particular to a pre-heating device and a pre-heating method for a combined stator of a plastic-encapsulated motor. Background technique [0002] The plastic-encapsulated motor is injection-molded on the combined stator (winding, iron core) through BMC (generally referring to unsaturated polyester glass fiber reinforced molding compound). The key process of the plastic-enclosed motor is the injection molding process of the plastic-encapsulated compound, which determines the production process The overall qualification rate of the plastic packaging molding process is related to the temperature and pressure of the injection mold, which determines the fluidity of the plastic packaging compound. [0003] During the injection molding process, the molding compound needs to undergo strong pressure and high temperature before injection molding. During injection molding, the mold core and cavi...
