Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer and more obvious, the present invention is further described in detail below with reference to the accompanying drawings and embodiments.

As shown in fig. 3 to 8, the utility model provides a solve remaining structure of ox horn runner, include: insert 1, and set up and be in the cold runner 2 and the plastic part appearance groove 3 of insert 1 top surface both sides, cold runner 2 and plastic part appearance groove 3 mutually perpendicular, and both are through setting up 4 connections are watered to ox horn in insert 1, the ox horn water 4 advance gluey mouthful one end with cold runner 2 intercommunication, its other end play jiao kou to insert 1 inside arc extend to with plastic part appearance groove 3 intercommunication, go out to glue mouthful one end inside and set up a play gluey spacer 14, it is perpendicular with plastic part appearance groove 3 position to go out gluey spacer 14, it splits into first play jiao kou 111 and second play jiao kou 122 to go out gluey mouthful one end.
