Abstract
The invention discloses a mold air pressure ejector device which comprises an upper mold base and a lower mold base. A T-shaped groove is formed in the middle of the lower mold base. An ejector rod is arranged in the T-shaped groove. The lower end of the ejector rod is connected with an external air pressure drive device. A concave mold body is arranged above the lower mold base. A profiled groove is formed above the middle of the concave mold body. A through groove allowing the ejector rod to pass through is formed in the lower portion of the middle of the concave mold body. A concave mold jacket for fixing the concave mold body is arranged around the concave mold body and fixedly connected with the lower mold base. The ejector rod is pushed by the external air pressure drive device to move upwards, and the function of ejecting out a plastic part is achieved through the concave mold body. The mold air pressure ejector device is simple in mold ejection structure and low in machining and making cost and fault rate, maintenance is convenient once the device goes wrong, and the device is suitable for various plastic molds.
Description
Technical field
The present invention relates to a kind of mould structure, particularly to a kind of Mold air pressure liftout attachment.
Background technology
Plastic mould is a kind of built-up plastics mould for compression moulding, extrusion molding, injection, blowing and low ratio foamed molding, its main cope match-plate pattern, lower bolster and core rod, do not appreciate and be provided with die cavity, so that the plastic made can the demoulding easily, technical staff in industry has done a lot of effort, in current industry, common practice is, strengthen the thickness of die shoe, by the thimble of die shoe, reaching to eject the effect of plastic, but this kind of ejecting structure of majority is complicated, difficulty of processing is big, the cost making mould is high, maintenance difficult.
Summary of the invention
In order to overcome drawbacks described above, the invention provides a kind of simple in construction, Mold air pressure liftout attachment that processing cost is low and easy to maintenance.
The present invention is to solve that its technical problem be the technical scheme is that a kind of Mold air pressure liftout attachment, including upper bolster and die shoe, it is provided with T-slot in the middle of described die shoe, a push rod it is provided with in described T-slot, the lower end of described push rod connects external pressure driving device, a die on the top of die shoe, described die middle upper part is type groove, in the middle of die, lower section is the groove passed through for push rod, described die is provided around the die overcoat of fixing die, and described die overcoat is fixing with die shoe to be connected.
As a further improvement on the present invention, the top of described push rod is provided with a parallels.
As a further improvement on the present invention, the side of described die overcoat is connected by screw and die shoe are fixing.
The invention has the beneficial effects as follows: the present invention promotes thimble to move upward by external pressure driving device, reach to eject the effect of plastic by die, the mold ejection structure of the present invention is simple, processing and fabricating cost is low, failure rate is low, once go wrong, easy to maintenance, it is adaptable to various plastic moulds.
Accompanying drawing explanation
Fig. 1 is present configuration schematic diagram;
Figure indicates: 1-upper bolster; 2-die shoe; 3-parallels; 4-T type groove; 5-push rod; 6-die; 7-type groove; 8-groove; 9-die overcoat.
Detailed description of the invention
In order to deepen the understanding of the present invention, below in conjunction with embodiment and accompanying drawing, the invention will be further described, and this embodiment is only used for explaining the present invention, is not intended that limiting the scope of the present invention.
Fig. 1 illustrates a kind of embodiment of the present invention a kind of Mold air pressure liftout attachment, including upper bolster 1 and die shoe 2, it is provided with T-slot 4 in the middle of described die shoe 2, a push rod 5 it is provided with in described T-slot 4, the lower end of described push rod 5 connects external pressure driving device, a die 6 on the top of die shoe 2, described die 6 middle upper part is type groove 7, in the middle of die 6, lower section is the groove 8 passed through for push rod, described die 6 is provided around the die overcoat 9 of fixing die 6, and described die overcoat 9 is fixing with die shoe 2 to be connected. The top of described push rod 5 is provided with a parallels 3, and the side of described die overcoat 9 is connected by screw is fixing with die shoe 2.
