Detailed Description
In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention is described in detail with reference to the accompanying drawings and the detailed description.
The traditional cradle handle pouring mold can only realize the pouring molding of one cradle handle at a time, and has the obvious defects of low production efficiency and high production cost. In view of this, the utility model provides a new cradle handle casting mold, its casting molding in the time that can realize two at least cradle handles to production efficiency has been promoted remarkably, manufacturing cost has been reduced.
As shown in fig. 2 to 4, the pouring mold for a cradle handle of an embodiment of the present invention includes a male mold 1 and a female mold 2, wherein:
the male mold 1 comprises a male mold seat 10, a male mold core 11 and a gate 15, the male mold core 11 is fixed on the male mold seat 10, a first flow channel 12 and four first mold grooves 13 located on the periphery of the first flow channel 12 and communicated with the first flow channel 12 are formed on the male mold core 11, and the gate 15 penetrates through the male mold seat 10 and the male mold core 11 and is communicated with the first flow channel 12.
