Description
Technical field
Injection mold technology is the utility model is related to, more particularly to a kind of tire burster injection mold.
Background technology
Injection mold, it is a kind of instrument for producing plasthetics, is also to confer to the complete mechanism of plasthetics and accurate dimension
Instrument.
At present, existing tire burster is as shown in figure 1, the main body 19 including strip, if being provided with the top surface of main body 19
Dry mounting groove 20, and length direction of some mounting grooves 20 along main body 19 is uniformly distributed, and each mounting groove 20 longitudinally through
In the bottom surface of body；Rotation slot 21 is provided with the internal groove side wall of mounting groove 20, length direction of the rotation slot 21 along main body 19 is set
And extend transversely through in the lateral wall of main body 19.When being processed using injection mold to the main body 19, it is necessary to be set on mould
The core_pulling pole for being molded rotation slot 21 is equipped with, oil cylinder control core_pulling pole and mould point are needed to use when main body 19 is molded and completed
From main body 19 can be taken out afterwards；But due to the length of rotation slot 21 is larger, so the length of core_pulling pole is also larger,
So during core pulling is carried out to core_pulling pole, the stroke of core_pulling pole is larger, that is to say, that oil cylinder needs longer piston
Core_pulling pole can be fully drawn out by bar；So when carrying out core pulling to core_pulling pole using oil cylinder, cylinder piston rod is close to mould
End easily occur significantly rock, greatly reduce the service life of oil cylinder.
Utility model content
In view of the deficienciess of the prior art, the purpose of this utility model is to provide a kind of tire burster injection mold, its
With the oil cylinder advantage that it is not susceptible to rock close to the end of mould lateral wall in core pulling.
Above-mentioned technical purpose of the present utility model technical scheme is that：A kind of tire burster injection mould
Tool, including dynamic model and cover half, core is provided with the cover half, die cavity, the core and die cavity are provided with the dynamic model
