Abstract
The utility model relates to a kind of two squeeze pin structures connected by push pedal, comprise hydraulic jack (1), sleeve pipe pressing plate (5), be arranged on the squeeze pin (6) in sleeve pipe pressing plate (5), one end die casting foundry goods (7) that described squeeze pin (6) stretches out from sleeve pipe pressing plate (5), the output piston of described hydraulic jack (1) connects push pedal (4) center above, in described push pedal (4), be that axisymmetrical is furnished with two squeeze pins (6) with output piston, described push pedal (4) is inner, squeeze pin (6) has water circulation groove around, described water circulation groove is built with cooling water (3).The utility model is applied a mill type cylinder and is connected in push pedal, acts on while ensure that two squeeze pins.And having done cooling water circulation in push pedal makes heat cannot be delivered in oil cylinder, ensure that the long-term effectiveness of oil cylinder.
Description
Technical field
The utility model belongs to die casting equipment technical field, particularly relates to a kind of two squeeze pin structures connected by push pedal.
Background technology
Foundry goods has two identical or close to identical thick large part, need to use two squeeze pin structure, and two squeeze pin is that an oil cylinder controls a squeeze pin (as shown in Figure 1) in existing pair of squeeze pin structure, although the squeezing effect of expection substantially can be reached during extruding, but once die casting overlong time is directly delivered to oil cylinder due to the heat of squeeze pin, oil cylinder is fragile or lost efficacy.And owing to being that the effect that two oil cylinders control separately to extrude occurs difference sometimes, cause two position quality to occur different.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of two squeeze pin structures connected by push pedal, applies a mill type cylinder and is connected in push pedal, acts on while ensure that two squeeze pins.And having done cooling water circulation in push pedal makes heat cannot be delivered in oil cylinder, ensure that the long-term effectiveness of oil cylinder.
The utility model solves the technical scheme that its technical problem adopts: provide a kind of two squeeze pin structures connected by push pedal, comprise hydraulic jack, sleeve pipe pressing plate, the squeeze pin be arranged in sleeve pipe pressing plate, described squeeze pin is from one end die casting foundry goods that sleeve pipe pressing plate stretches out, the output piston of described hydraulic jack connects center above push pedal, be that axisymmetrical is furnished with two squeeze pins in described push pedal, with output piston, have water circulation groove around described push pedal inside, squeeze pin, described water circulation groove is built with cooling water.
The upper end of described squeeze pin is arranged in the through hole of push pedal both sides, and the upper end of through hole is equipped with plug, is shut in push pedal one end of squeeze pin.
Described plug is two plugs.
Beneficial effect
The utility model has the advantage of, apply a mill type cylinder and be connected in push pedal, act on while ensure that two squeeze pins.Squeeze pin is fixed in push pedal and shuts with two plug; And for ensureing the dispersion of heat, push pedal has been done cooling water circulation makes heat cannot be delivered in oil cylinder, ensure that the long-term effectiveness of oil cylinder, thus ensures the uniformity of typical products in mass production internal soundness, improves the quality of products, enhances productivity.
Accompanying drawing explanation
Fig. 1 is the structural representation of prior art.
Fig. 2 is structural scheme of mechanism of the present utility model.
Detailed description of the invention
Below in conjunction with specific embodiment, set forth the utility model further.Should be understood that these embodiments are only not used in restriction scope of the present utility model for illustration of the utility model.In addition should be understood that those skilled in the art can make various changes or modifications the utility model, and these equivalent form of values fall within the application's appended claims limited range equally after the content of having read the utility model instruction.
As shown in Figure 2, a kind of two squeeze pin structures connected by push pedal, comprise hydraulic jack 1, sleeve pipe pressing plate 5, the squeeze pin 6 be arranged in sleeve pipe pressing plate 5, described squeeze pin 6 is from one end die casting foundry goods 7 that sleeve pipe pressing plate 5 stretches out, the output piston of described hydraulic jack 1 connects push pedal 4 center above, be that axisymmetrical is furnished with two squeeze pins 6 in described push pedal 4, with output piston, have water circulation groove around described push pedal 4 inside, squeeze pin 6, described water circulation groove is built with cooling water 3.
The upper end of described squeeze pin 6 is arranged in the through hole of push pedal 4 both sides, and the upper end of through hole is equipped with plug 2, is shut in push pedal 4 one end of squeeze pin 6.
Described plug 2 is two plugs.
In use, first cooling water recirculation system is opened, pressing plate 5 inner cooling water is flowed, primer fluid compressing cylinder 1 afterwards, control pressing plate 5 to move downward, make to be arranged symmetrically two squeeze pins 6 be arranged on below pressing plate 5 to move along sleeve pipe pressing plate 5, and stretch out from the hole below sleeve pipe pressing plate 5 die casting is carried out to foundry goods 7.
Claims (3)
1. the two squeeze pin structures connected by push pedal, comprise hydraulic jack (1), sleeve pipe pressing plate (5), be arranged on the squeeze pin (6) in sleeve pipe pressing plate (5), one end die casting foundry goods (7) that described squeeze pin (6) stretches out from sleeve pipe pressing plate (5), it is characterized in that, the output piston of described hydraulic jack (1) connects push pedal (4) center above, in described push pedal (4), be that axisymmetrical is furnished with two squeeze pins (6) with output piston, described push pedal (4) is inner, squeeze pin (6) has water circulation groove around, described water circulation groove is built with cooling water (3).
2. a kind of two squeeze pin structures connected by push pedal according to claim 1, it is characterized in that, the upper end of described squeeze pin (6) is arranged in the through hole of push pedal (4) both sides, and the upper end of through hole is equipped with plug (2), is shut in push pedal (4) one end of squeeze pin (6).
