Specific embodiment
It is specific embodiment of the utility model and in conjunction with attached drawing below, the technical solution of the utility model is made further
Description, but the utility model is not limited to these examples.
As shown in Figure 1 and Figure 2, this oil duct extrusion structure for being used for automatic gear-box die casting, comprising: lower template 1；
It offers the first oil hole 2；First compression assemblies, activity are inserted in the first oil hole 2, plug in the first compression assemblies
There are two first pressure rams 3；Second compression assemblies are set to the top of lower template 1, and two pieces the are inserted in the second compression assemblies
Two pressure rams 4, the second compression assemblies lower end are also inserted with squeeze pin 5.
Product 14 forms in lower template 1, and the first compression assemblies can from the bottom to top squeeze product 14, squeezes
When, two first pressure rams 3 stretch in product 14 simultaneously, so that product 14 is formed simultaneously two oil ducts, in this way can
The phenomenon that being not in shrinkage cavity when guarantee oil duct formation, two the second pressure rams 4 can also make product 14 form two simultaneously
Oil duct, and the first compression assemblies and the second compression assemblies opposition are arranged, the first compression assemblies form oil to product 14 from the bottom to top
Road, second squeezes gradually from the bottom to top to Chen Pin formation oil duct, can guarantee the uniform force of product 14 in this way, product 14 will not
The phenomenon that misplacing in lower template 1, it can preferably guarantee the quality of product 14.
Squeeze pin 5 is on the one hand to form specific shape on 14 surface of product, is on the other hand to be capable of fixing product
14, so that product 14 is more stable when forming oil duct.
