Abstract
The utility model relates to a kind of gradient jogger hole preventing from push rod and core rod from killing fractureing, comprise cover half core and moving-mould-core, it is cover half core above moving-mould-core, it is die cavity between cover half core and moving-mould-core, foundry goods is had in die cavity, below cast top position, moving-mould-core has thick stick hole, top, top is provided with push rod in thick stick hole, and axial line and the bus of thick stick hole, top inwall of push rod have the little angle of 0.2 degree.The utility model employs gradient jogger hole structure, in actual production process, push rod is stressed and heat inflate compression causes push rod and hole frictional force to increase, and 0.2 degree of inclined-plane effectively avoids the friction of push rod and core rod, the position rubbed with push rod only has the straight mating surface of about 5mm above, therefore the frictional force of core rod and push rod will reduce greatly, eject very smooth and easy in actual use, ensure the continuity of Die Casting.
Description
Technical field
The utility model belongs to technical field of mold, particularly relates to a kind of gradient jogger hole preventing from push rod and core rod from killing fractureing.
Background technology
Ejection system is the important component part of mould, and foundry goods package power is excessive, and the position that heat is concentrated ejects comparatively difficulty, is easy to cause push rod to be pulled in actual Die Casting process, and the problem such as fracture, and this directly affects production efficiency and the stability of mould.
The cooperation section of push rod and core rod is all straight flange, gap is 0.03-0.05mm, when foundry goods package power is excessive or heat is too high, because the contact surface of push rod and core rod is excessive, the impact of frictional force and push rod is squeezed, ram surface there will be to be pulled, and continues to use to occur breakage phenomenon unavoidably, this will cause the interruption of normal Die Casting, stops production.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of gradient jogger hole preventing from push rod and core rod from killing fractureing, to solve the problem easily fractureed in the use procedure of existing mold push rod.
The utility model solves the technical scheme that its technical problem adopts: provide a kind of gradient jogger hole preventing from push rod and core rod from killing fractureing, comprise cover half core and moving-mould-core, it is cover half core above moving-mould-core, it is die cavity between cover half core and moving-mould-core, foundry goods is had in described die cavity, below cast top position, moving-mould-core has thick stick hole, top, top is provided with push rod in thick stick hole, and axial line and the bus of thick stick hole, top inwall of push rod have the little angle of 0.2 degree.
Described push rod top section is that push rod coordinates section.
Described push rod coordinates the push rod stage casing of pars infrasegmentalis to be that wide arc gap gradient coordinates section.
Beneficial effect
The utility model employs gradient jogger hole structure, the processing of this scheme is more difficult, straight flange mating surface and gradient mating surface need twice slow wire feeding to process, processing cost is slightly high, stress some the emphasis positions being used in foundry goods, in actual production process, push rod is stressed and heat inflate compression causes push rod and hole frictional force to increase, and 0.2 degree of inclined-plane effectively avoids the friction of push rod and core rod, the position rubbed with push rod only has the straight mating surface of about 5mm above, therefore the frictional force of core rod and push rod will reduce greatly, eject very smooth and easy in actual use, ensure the continuity of Die Casting.

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.
Embodiment 1
As shown in Figure 2 to 3, a kind of gradient jogger hole preventing from push rod and core rod from killing fractureing, comprise cover half core 1 and moving-mould-core 2, moving-mould-core 2 is cover half core 1 above, be die cavity between cover half core 1 and moving-mould-core 2, in die cavity, have foundry goods 4, below foundry goods 4 tip position, moving-mould-core 2 has thick stick hole 3, top, top is provided with push rod 7 in thick stick hole 3, and axial line and the bus of thick stick hole 3, top inwall of push rod 7 have the little angle 5 of 0.2 degree.
Described push rod 7 top section is that push rod coordinates section 8.
Described push rod coordinates push rod 7 stage casing of section 8 bottom to be that wide arc gap gradient coordinates section 6.
In actual production process, push rod 7 is stressed and heat inflate compression causes push rod 7 and hole frictional force to increase, and 0.2 degree of inclined-plane effectively avoids the friction of push rod 7 and core rod, the position rubbed with push rod 7 only has the straight mating surface of about 5mm above, therefore the frictional force of core rod and push rod 7 will reduce greatly, eject very smooth and easy in actual use.
Claims (3)
