Detailed Description

The present utility model will be described in detail with reference to the accompanying drawings.

Referring to fig. 1-2, the present embodiment provides a mold structure with correction function, which is applied to injection molding and encapsulation of a wire of a distribution ring of an automobile motor. The die structure comprises an upper die body 1, a lower die body 2 positioned below the upper die body 1, a die cavity 4 formed in the lower die body 2 and a correcting structure 5 positioned in the die cavity 4.

The upper die body 1 is provided with a driving assembly for driving the upper die body 1 to vertically move. The upper die body 1 is provided with protruding columns facing the lower die body 2, the lower die body 2 is provided with column grooves matched with the protruding columns, the number of the protruding columns is four, and the protruding columns are uniformly distributed at the peripheral positions of the die cavity 4. In this embodiment, in order to achieve accurate alignment of the upper mold body 1 and the lower mold body 2, tight mold clamping is achieved, and a protrusion is used to match a post groove to provide mold clamping guidance. An injection molding opening 3 is formed in the upper die body 1 in a penetrating manner, and when the upper die body 1 and the lower die body 2 are assembled, the injection molding opening 3 is communicated with a cavity 4.

The correcting structure 5 comprises a sleeve 51 fixedly penetrating through the lower die body 2, spring steel 52 positioned in the sleeve 51, pin slots 53 formed in the spring steel 52, and rubber gaskets 54 fixedly wrapping the inner wall of the sleeve 51. Wherein the spring steel 52 is interference fit with the sleeve 51 by a rubber packing 54, the rubber packing 54 is filled between the sleeve 51 and the spring steel 52, and in this embodiment, the rubber packing 54 is provided to increase friction, thereby providing a supporting force of the spring steel 52 extending when the mold is not closed. In this embodiment, when the sleeve 51 is exposed out of the spring steel 52, the Pin slot 53 is opened based on the cross slot so that the Pin of the wire rod of the distribution ring of the automobile motor can be conveniently inserted into the corresponding Pin slot 53.

The bending device aims at the problems that after an automobile motor distribution ring wire is bent in an arc shape, rebound exists, the Pin foot position after bending is deflected by 0.5-0.8, and each Pin is required to be broken off by hand due to dislocation when the Pin foot is swung into a positioning hole of a die, so that the production efficiency is affected, and the product yield is unstable. In this embodiment, the correction structure 5 is provided to align the positions of pins of the motor distribution ring wire Pin of the automobile. In the first state, the spring steel 52 is exposed out of the sleeve 51, and the Pin slot 53 can be expanded under the action of the cross-shaped slot so as to facilitate placement of Pin pins of the wire rod of the distribution ring of the automobile motor because the spring steel 52 is not constrained by the sleeve 51.
