Abstract
The utility model discloses an integral type pressurization piston of a pressure injection mechanism of a die-casting machine. The piston and a piston rod part adopt an integrated structure, a one-way valve core is arranged in a cavity of the piston rod part at the left end of the piston, a middle hole of the one-way valve core is sleeved on a supporting rod of the valve core, the right end of the piston adopts a cylindrical guide rod, and a valve face corresponding to the one-way valve core is arranged at the junction of an inner hole of the guide rod and the cavity of the piston rod part at the left end of the piston; a spring is mounted in the middle hole of the one-way valve core; and a seal ring-shaped groove is respectively formed on the excircles of the piston rod part and the guide rod. The utility model adopts the scheme that a multi-component assembled structure is changed into the integral type, the structure is simple, and the assembly and the maintenance are convenient. By adopting the integral type pressurization piston, the phenomenon of oil leakage between split-type combined sealing surfaces and sealing parts is eliminated, the operational reliability of the die-casting machine is improved, and at the same time, the manufacturing technique is simplified, and the cost is reduced.
Description
Technical field
The utility model belongs to the die casting equipment technical field, relates to a kind of die casting machine injection modular construction, is specifically related to a kind of die casting machine injection mechanism monoblock type charged piston.
Background technology
What the charged piston in the existing cold chamber die-casting machine injection mechanism pressurizing cylinder mostly adopted is the multicompartment fabricated construction, and part is many, assembles loaded down with trivial details.During the equipment operation, tend to cause the loosening of fastening bolt, the phenomenon of leaking in also can taking place between the combination seal.Because charged piston is assembled, in establish nonreturn valve core sealed precision height, adopt the morpheme worker's difference and the dimensional tolerance that improve each assembly to solve sealed precision, cause problems such as the parts machining process difficulty is big, cost height.
Summary of the invention
The purpose of this utility model is that existing assembly type charged piston structure is improved, a kind of die casting machine injection mechanism monoblock type charged piston is provided, monoblock type charged piston after the improvement is simple in structure, the phenomenon that does not have leakage of oil between the seal, improved the functional reliability of die casting machine, simplify manufacturing process, reduced cost.Made things convenient for the I﹠M of injection mechanism simultaneously.
The technical scheme that the utility model adopted is, a kind of die casting machine injection mechanism monoblock type charged piston, described piston and piston rod portion are overall structure, be provided with a nonreturn valve core in the die cavity of described piston left end piston rod portion, the mesopore of nonreturn valve core is sleeved on the spool support bar, the right-hand member of piston is a tubular guide post, and the die cavity confluce of guide post endoporus and piston left end bar portion is provided with the corresponding valve face with nonreturn valve core.
Die casting machine injection described in the utility model mechanism monoblock type charged piston, its feature also be,
In the mesopore of described nonreturn valve core spring is housed.
The cylindrical of described piston rod portion and guide post is provided with closure gasket groove.

The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
A kind of die casting machine injection mechanism monoblock type charged piston, as shown in Figure 1, described piston 1 is an overall structure with piston rod portion, be provided with a nonreturn valve core 4 in the die cavity 3 of described piston 1 left end piston rod portion 2, the mesopore of nonreturn valve core 4 is sleeved on the spool support bar 5, the right-hand member of piston 1 is a tubular guide post 6, and die cavity 3 confluces of guide post 6 endoporus and piston 1 left end bar portion 2 are provided with the corresponding valve face 7 with nonreturn valve core 4.
The cylindrical of described piston rod portion 2 and guide post 6 is provided with closure gasket groove 9.
The utility model monoblock type charged piston is in the pressurizing cylinder of die casting machine injection mechanism of packing into, wherein piston 1 left end piston rod portion 2 is contained in the injection oil cylinder of die casting machine injection mechanism, the guide post 6 of piston 1 right-hand member is contained in the main oil-hole of injection mechanism injection oil circuit body, and stable working state is reliable.
This die casting machine injection mechanism monoblock type charged piston, change piston 1, piston rod portion 2 and guide post 6 multicompartment fabricated constructions into monoblock type, in the die cavity 3 of piston 1 left end piston rod portion 2, by spool support bar 5 suit nonreturn valve cores 4, the charged piston structure is improved, has made things convenient for assembling and maintenance.The monoblock type charged piston has solved split combination sealing face, and the phenomenon of leakage of oil between the seal has improved the functional reliability of die casting machine, has also simplified manufacturing process simultaneously, has reduced cost.
Above-mentioned embodiment is an example of the present utility model; not enforcement and the interest field that is used for limiting utility model; all equivalences of making according to the described content of the utility model patent protection scope change and modify, and all should be included in the utility model claim.
