Abstract

The utility model discloses a die casting die of microdiecast piece, including front mould benevolence, back mould benevolence, thimble, it has first die cavity and flow gate to open in the front mould benevolence, it has the second die cavity to open in the back mould benevolence, the second die cavity includes that a plurality of products become the die cavity, become watering of die cavity and flow gate intercommunication and become the overflow launder that the die cavity feeds through with a plurality of products with the product, it has a plurality ofly and thimble complex jack to open at the bottom of the overflow launder, the thimble inserts the jack. The utility model discloses during implementation, netted linking to each other of product of utilizing overflow launder and the cinder ladle that waters and die -casting clout to make the processing of product shaping intracavity obtain, utilize thimble and cinder ladle in the overflow launder to cooperate, carry out the roof pressure to the cinder ladle, and then make a plurality of overall product ejection of compact, avoided the direct contact of thimble with the product, avoided the production of burr.

Description

A kind of die casting of accurate die casting

Technical field

The utility model relates to a kind of die casting, specifically a kind of die casting that product impulse-free robustness ejects when can realize accurate die casting discharging.

Background technology

A lot of die casting is higher to dimensional requirement precision, in existing die casting, and independent separate between the cinder ladle connected with product and cinder ladle, when ejecting, for realizing self-emptying, the general immediate roof of the push rod in mould is pressed on product, contact with product external surfaces and coordinate, product realizes ejecting via push rod.After push rod is moved to cinder ladle place, existing cinder ladle structure intensity is not enough, and when jack-up discharging, bag very easily departs from product again, causes discharging failure.

Because the design of current structure of cast die limit, after making push rod that product is ejected discharging, can be jagged on the contact position of product and push rod, affect follow-up assembling and the use of product, so, in actual production process, need to increase deburring operation toward contact, waste a large amount of manpower and materials, improve production cost, the requirement of present enterprise to product automated production in enormous quantities can not be met.

Utility model content

The purpose of this utility model is to overcome the existing die casting deficiency existing when discharging, provides a kind of die casting of accurate die casting.

For achieving the above object, the technical scheme that the utility model adopts is:

A die casting for accurate die casting, comprises front cavity, rear cavity, thimble, described front cavity has the first die cavity and ingate;

Described rear cavity has the second die cavity;

The overflow launder that described second die cavity comprises some formed product chambeies, the running channel be communicated with formed product chamber and ingate and is communicated with some formed product chambeies;

Some jacks coordinated with thimble are had at the bottom of described overflow launder;

Described thimble inserts jack.

Further, described running channel bottom surface has some jacks coordinated with thimble, is inserted with a thimble in jack.

When the utility model is implemented, the cinder ladle of overflow launder and running channel and die casting clout is utilized to make in formed product chamber, to process the product obtained netted connected, thimble is utilized to coordinate with the cinder ladle in overflow launder, top pressure is carried out to cinder ladle, and then make some Total Product dischargings, avoid thimble to contact with the direct of product, avoid the generation of burr.
