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.

The female die 2 comprises a female die holder 20 and a female die core 21, the female die core 21 is fixed on the female die holder 20, a second flow passage 22 corresponding to the first flow passage 12 and four second die grooves 23 located on the periphery of the second flow passage 22 and communicated with the second flow passage 22 are formed in the female die core 21, the four second die grooves 23 correspond to the four first die grooves 13 one by one, and a contact pin 25 is arranged in each second die groove 23.

The male die 1 can move between a die assembly position and a die separation position, so that the die assembly and the die separation with the female die 2 are realized.

As shown in fig. 5 to 6, when the male mold 1 moves to the mold closing position, the male mold 1 and the female mold 2 are closed, the first runner 12 and the second runner 22 are buckled to form a closed runner, the four first cavities 13 and the four second cavities 23 are buckled to form four closed molding cavities, the gate 15 is communicated with the runner, and the runner is communicated with the four molding cavities. At this time, the molten casting material is injected through the gate 15, and the casting material is divided into four molding cavities through the runner. After the casting material is cooled and solidified, the male die 1 is moved to a die parting position, the male die 1 and the female die 2 are separated, and at the moment, four formed leather ring frame handles can be taken out. Because each forming die cavity is provided with a pin 25, the formed handle of the leather ring frame is provided with a pin hole complementary with the pin 25.

Of course, in other embodiments, two or three other numbers of molding cavities may be provided.

Optionally, four guide posts 14 located on the periphery of the core insert 11 are disposed on the male mold base 10, and a plurality of guide holes 24 matching with the four guide posts 24 are disposed on the female mold base 20.
