Detailed Description

In order to facilitate the understanding of those skilled in the art, the present invention will be further described with reference to the following examples, which are not intended to limit the scope of the present invention.

As shown in fig. 1 to 7, a side-abrupting water gap mechanism for preventing trapped air for a mold comprises a lower template 1, at least two mold blocks 2 are connected to the side surface of the lower template 1, the at least two mold blocks 2 are arranged around the lower template 1, at least two exhaust grooves 23 are arranged on the front side surface of the mold blocks 2, the depth of the exhaust grooves 23 is 0.012-0.018 mm, a moving block 3 is connected to the rear side surface of the mold blocks 2, grooves are respectively arranged on the edges of the moving block 3 and the mold blocks 2, the groove of the moving block 3 and the groove of the mold blocks 2 are matched to form a diversion groove 4, the mold blocks 2 are provided with a conveying groove 21 communicated with the diversion groove 4, the moving block 3 is provided with an abrupting groove 31 communicated with the diversion groove 4, a lower groove 32 is arranged on the bottom surface of the abrupting groove 31, the moving block 3 is provided, the end of the connecting member 33 is screwed to the mold block 2, one end of the elastic member 34 abuts against the moving block 3, and the other end of the elastic member 34 abuts against the mold block 2.

In the actual operation of this embodiment, die-casting process after the compound die is accomplished, can push into a little gas when the colloidal sol pushes the die cavity, and these some gas can lead to the colloidal sol shaping not to be expected to produce the defective products, nevertheless through the exhaust duct 23 that sets up a plurality of specific depths at the leading flank of model block 2, realize quick exhaust and solve the trapped air problem, neither can be because of the too shallow unable rapid in time exhaust of depth in this specific depth's the scope, also can not be because of too big influence the colloidal sol shaping shape, the practicality is strong. After glue injection is completed, the moving block 3 can be driven to move successively when the mold is opened, the moving block 3 can make the diversion trench 4 split when moving backwards initially, so that the glue injection port is broken, the diversion trench 4 plays a role in breaking the glue injection drainage and simultaneously breaking a plurality of glue injection ports when breaking, the elastic piece 34 can push the model block 2 in the backward moving process of the moving block 3 so that the model block 2 cannot move backwards along with the moving block 3 at first, so that the diversion trench 4 is broken, the model block 2 can be delayed to follow the moving block 3 to move backwards due to the connecting piece 33 after moving backwards for a certain distance when the moving block 3, and therefore the model block 2 is far away from a molded product to realize demolding. Due to the design of the delayed linkage structure of the diversion trench 4, the moving block 3 and the model block 2, the effects of side breaking and automatic falling of the glue injection port are realized efficiently and quickly, and the practicability is high.

In this embodiment, the cross-sectional shape of the breaking groove 31 is a triangle. The shape design of the breaking groove 31 enables the glue injection port to follow stably when the moving block 3 is pulled backwards, backward movement of the moving block 3 cannot occur, but the glue injection port does not follow, and the lower groove 32 is also arranged to enhance the stability of the pulling backwards.
