Abstract
The utility model discloses a die-casting die with a local pressurization device. The die comprises a base plate, a lower fixed die and an upper movable die, wherein the lower fixed die comprises a fixed die frame and a fixed die core, the fixed die core is connected with a material inlet channel communicated with the outside world, the upper movable die comprises a movable die frame and a movable die core, a casting die cavity is formed by the movable die core and the fixed die core, an oil cylinder is arranged in the movable die frame, a piston rod of the oil cylinder is connected with a pressurization pin through a pressurization pin connecting sleeve, a countersunk head is arranged on the top of the pressurization pin, a groove matched with the countersunk head is formed in the top of the piston rod of the oil cylinder, the countersunk head is embedded in the groove, a pressurization sleeve is arranged in the movable die core, and the pressurization pin penetrates through the pressurization sleeve when moving vertically along with the piston rod and entering the movable die core. The die-casting die with the local pressurization device has the advantages that when a product is complex in structure, air holes are prone to forming in local parts of the product or the local parts of the product are prone to loosening, through the oil cylinder, the piston rod drives the pressurization pin to pressurize the local parts of the product, and the phenomenon that air holes are formed in local parts or local parts loosen can be avoided.
Description
Technical field
The utility model relates to technical field of mold, particularly a kind of die casting with local pressurizing device.
Background technology
When using die casting to produce, due to the complicated structure of portioned product, easily in product, form pore or wall thickness regions interior tissue loose, cause can't meet the quality requirement of product.
Summary of the invention
The purpose of this utility model is in order to solve above-mentioned the deficiencies in the prior art, thereby provides a kind of simple in structure and can solve again the die casting with local pressurizing device of local pore and loose phenomenon.
To achieve these goals, a kind of die casting with local pressurizing device that the utility model is designed, comprise base plate, lower cover half and upper dynamic model, described lower cover half comprises cover half frame and cover half core, described cover half core is connected with the pan feeding passage communicating with the external world, described upper dynamic model comprises dynamic model frame and moving-mould-core, described moving-mould-core and cover half core form die cavity to be cast, in described dynamic model frame, be provided with oil cylinder, the piston rod of described oil cylinder is connected with loaded pins by loaded pins adapter sleeve, described loaded pins top is provided with countersunk head, the piston rod part of described oil cylinder is provided with the groove matching with countersunk head, described countersunk head is embedded in groove, in described moving-mould-core, be provided with pressure cuffs, described loaded pins moves up and down while entering moving-mould-core through pressure cuffs with piston rod.
When die casting machine injection, by the time, adjust cylinder action, when injection approach to finish, oil cylinder starts action and is pressurizeed in product part, and with this, solving product part has pore and the phenomenon such as loose.
A kind of die casting with local pressurizing device that the utility model obtains, its technique effect is: when product structure more complicated, to local pore or the loose place of easily forming of product, by the effect of oil cylinder, piston rod drives loaded pins, pressurizeed in product part, solve local pore or the situation such as loose.
Accompanying drawing explanation
Fig. 1 is the structure of cast die schematic diagram that the utlity model has local pressurizing device;
Fig. 2 is the local enlarged diagram of the utility model A.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated.
As shown in Fig. 1 and 2, a kind of die casting with local pressurizing device that the utility model provides, comprise base plate 1, lower cover half and upper dynamic model, described lower cover half comprises cover half frame 2 and cover half core 3, described cover half core 3 is connected with the pan feeding passage 4 communicating with the external world, described upper dynamic model comprises dynamic model frame 5 and moving-mould-core 6, described moving-mould-core 3 forms die cavity to be cast with cover half core 6, in described dynamic model frame 5, be provided with oil cylinder 7, the piston rod 13 of described oil cylinder 7 is connected with loaded pins 9 by loaded pins adapter sleeve 8, described loaded pins 9 tops are provided with countersunk head 11, piston rod 13 tops of described oil cylinder 7 are provided with the groove 12 matching with countersunk head 11, described countersunk head 11 is embedded in groove 12, in described moving-mould-core 6, be provided with pressure cuffs 10, when entering moving-mould-core 6 with moving up and down of piston rod 12, described loaded pins 9 passes pressure cuffs 10.
Piston rod 13 by oil cylinder 7 in the present embodiment drives loaded pins 9 to move up and down, and the tangible one-tenth pore in part or loose place are pressurizeed.
