Abstract
The utility model provides a pneumatic double-demolding mechanism of an injection mold. The mechanism comprises an upper doubling plate and a lower doubling plate, wherein a cavity is connected to the lower part of the upper doubling plate; a mold leg is mounted on the lower doubling plate; an upper ejector retainer plate and a lower ejector retainer plate are arranged in the mold leg; a top rod is connected to the upper ejector retainer plate; a core is mounted on the mold leg; a mold cavity is formed between the core and the cavity; a formed product is in the mold cavity; and the top rod passes through the core to be contacted with the product. The pneumatic double-demolding mechanism is characterized in that a compressed air check valve is mounted in the cavity, wherein the compressed air check valve comprises a valve body; an air inlet hole is formed on the valve body; an air inlet passage is formed in the cavity; the air inlet hole is communicated with an air source by the air inlet passage; a valve hole is formed in the valve body; a compression spring is mounted in the valve hole; a nut is mounted on the compression spring; the nut is fitted with the inlet of the valve hole; a valve block is mounted at the outlet of the valve hole; and the valve block is contacted with the product. In the scheme, pneumatic air blowing is adopted, and the pneumatic double-demolding mechanism is simple in structure, convenient to machine and low in cost.
Description
Technical field
This practical new model relates to pneumatic pair of mould emptier of a kind of injection mold, belongs to the mould of plastics field.
Background technology
At present, when producing the plastic product of similar containers, the structure of the traditional injection moulding mould normally core of mould stretches into the product inwall, and the die cavity of mould is coated on the product outer wall, and the gap between core and the die cavity constitutes the die cavity of product.After the product injection mo(u)lding,, coat at die cavity under the effect of power because die cavity is coated on the outer wall of product; When the mould die sinking, plastic product usually can be stayed in the die cavity of mould, and in the cavity side of mould liftout attachment is not installed generally; Therefore, can cause the product snap gauge, can't deviate from automatically; Like untimely processing, cause mould generation mechanical breakdown easily, influence is produced.
Summary of the invention
The purpose of the utility model is in order to overcome the shortcoming of prior art, to provide a kind of employing compressed air to be blown into, product is stayed on the core, with core die sinking action operation, avoid taking place the product snap gauge, ejecting pneumatic pair of mould emptier of injection mold smoothly.
The technical scheme of pneumatic pair of mould emptier of the utility model injection mold is: comprise compound plate and following compound plate on the mould, last compound plate connects die cavity down, and the mould pin is installed on the following compound plate, and ejector retainner plate and following ejector retainner plate are set in the mould pin; Connect push rod on the last ejector retainner plate, on the mould pin core is installed, constitute die cavity between core and the die cavity, the product of moulding is arranged in the die cavity; Push rod passes core and contacts with product, it is characterized in that the compressed air check valve is installed in the described die cavity, and described compressed air check valve comprises valve body; Be shaped on air admission hole on the valve body, in die cavity, be shaped on inlet channel, air admission hole is communicated with source of the gas through inlet channel; Be shaped on valve opening in the valve body, the compression spring is installed in the valve opening, on the compression spring nut is installed; Nut cooperates with the import of valve opening, is equipped with valve block in the outlet of valve opening, and valve block contacts with product.
Pneumatic pair of mould emptier of the injection mold of the utility model, after the product injection mo(u)lding, source of the gas (generally being air pump) gets into check valve through inlet channel to compressed air, and compressed air forces the valve block of check valve to have downtrend.After the formed product, injection machine power drives core and die cavity die sinking, and core separates with die cavity; Valve block will eject a bit of distance with product from die cavity; Product is kept on the core, with core die sinking action operation downwards, after the die sinking end; Upper and lower ejector retainner plate drives push rod and directly product is ejected outside the mould, and the demoulding is accomplished.This programme adopts pneumatic air blowing, and product can be bonded in the die cavity, avoids taking place product and drops in the die cavity, and product is with core die sinking action operation downwards, and the ejection system of mould ejects product.Adopt pneumatic air blowing simple in structure, easy to process, cost is economized.
Pneumatic pair of mould emptier of the injection mold of the utility model, described valve outer wall is equipped with sealing ring, and good seal performance prevents gas leakage.
Description of drawings
Fig. 1 is pneumatic pair of mould emptier structural representation of the utility model injection mold.
The specific embodiment
The utility model relates to pneumatic pair of mould emptier of a kind of injection mold, and is as shown in Figure 1, comprises compound plate 1 and following compound plate 2 on the mould, and last compound plate connects die cavity 31 time; Mould pin 4 is installed on the following compound plate 2, ejector retainner plate 5 and following ejector retainner plate 6 are set in the mould pin, connect push rod 7 on the last ejector retainner plate; Core 8 is installed on the mould pin 4, is constituted die cavity between core 8 and the die cavity 3, the product 9 of moulding is arranged in the die cavity; Push rod 7 passes core 8 and contacts with product 9, it is characterized in that the compressed air check valve is installed in the described die cavity 3, and described compressed air check valve comprises valve body 10; Be shaped on air admission hole 15 on the valve body, in die cavity 3, be shaped on inlet channel 16, air admission hole 15 is communicated with source of the gas through inlet channel 16; Be shaped on valve opening 11 in the valve body, compression spring 12 is installed in the valve opening, on the compression spring nut 13 is installed; Nut 13 cooperates with the import of valve opening 11, is equipped with valve block 14 in the outlet of valve opening 11, and valve block 14 contacts with product 9.After the product injection mo(u)lding, source of the gas (generally being air pump) gets into check valve through inlet channel 16 to compressed air, and compressed air forces the valve block 14 of check valve to have downtrend.After the formed product, injection machine power drives core 8 and die cavity 3 die sinkings, and core 8 was opened with die cavity in 3 minutes; Valve block 14 will eject a bit of distance with product 9 from die cavity 3; Product 9 is kept on the core 8, with core 8 die sinkings action operation downwards, after the die sinking end; Upper and lower ejector retainner plate 5,6 drives push rod 7 and directly product 9 is ejected outside the mould, and the demoulding is accomplished.This programme adopts pneumatic air blowing, and product can be bonded in the die cavity, avoids taking place product and drops in the die cavity, and product is with core die sinking action operation downwards, and the ejection system of mould ejects product.Adopt pneumatic air blowing simple in structure, easy to process, cost is economized.Described valve body 10 outer walls are equipped with sealing ring 17, and good seal performance prevents gas leakage.
