Abstract
The utility model discloses a gas-assisted die clearance ejection pin mechanism. In the technical scheme, the middle part of a die core is provided with an ejection pin slot penetrating in the vertical direction, a gas-assisted clearance ejection pin is inserted in the ejection pin slot, a clearance formed between the middle part of the gas-assisted clearance ejection pin and the ejection pin slot of the die core, a gas channel is arranged in the die core, one end of the gas channel is communicated with the outside, and the other end of the gas channel is communicated with the clearance. Therefore, the outside compressed air can flow into the clearance through the gas channel, and can be rapidly guided into space between the project ejection surface and the die core once the gas-assisted clearance ejection pin is ejected out, thereby eliminating the vacuum of the product ejection surface, facilitating the smooth ejection of the product for die stripping, and greatly reducing the deformation of the product caused by the excessively large ejection force.
Description
Technical field
The utility model relates to a kind of mould accessory, specifically a kind of ejector pin mechanism that can make the smooth ejection device of plastic cement products.
Background technology
Thimble is the accessory of plastic mould, is used for plastic mould, and thimble also can be push rod, pin, middle pin, holder pin etc., and in mould, thimble is used for plastic cement products is separated from mould.
But during the plastic cement products moulding, mould inside is a vacuum, because product is influenced by vacuum, thimble is difficult to smoothly it be ejected, and causes the distortion of plastic cement products when the thimble ejecting force is excessive easily.
Summary of the invention
In order to address the above problem, the utility model provides a kind of die clearance gas to assist ejector pin mechanism, vacuum problem when the auxilliary ejector pin mechanism of this die clearance gas can solve most of mold releasability can eject product smoothly, can alleviate the distortion that product causes because of ejecting force is excessive greatly.
The utility model for the technical scheme that solves its technical problem and adopt is:
A kind of die clearance gas is assisted ejector pin mechanism, the mold cores middle part offers the thimble groove of up/down perforation, be interspersed with gas auxilliary thimble in gap in the thimble groove, gas auxilliary thimble upper end diameter in described gap is greater than its middle part diameter, there is the gap between auxilliary thimble middle part outer surface of described gap gas and described thimble groove inner surface, its upper end did not fit tightly with thimble groove inner surface when gas auxilliary thimble in described gap ejected, be provided with gas passage in the described mold cores, described gas passage one end communicates with described gap with exterior and its other end, external compression gas can feed from described gas passage, gas auxilliary thimble lower diameter in described gap is greater than its middle part diameter, auxilliary thimble bottom of described gap gas and described thimble groove fit tightly, described gas passage when gas auxilliary thimble in described gap ejects, described gap and product eject the face three and communicate.There is the gap in the thimble groove that gas auxilliary thimble in gap of the present utility model is processed into the middle part with mold cores, Wai Bu Compressed Gas can be entered in this gap by gas passage like this, the moment Compressed Gas that is ejected when the auxilliary thimble of gap gas imports product rapidly and ejects between face and mold cores from the gap, remove the vacuum state that product ejects face, can make the smooth ejection device of product, alleviate the distortion that product causes because of ejecting force is excessive greatly.
Further technical scheme of the present utility model is:
The contact-making surface of described gas passage and mold cores is provided with first sealing ring (preventing that Compressed Gas from leaking) that is used for sealing gas.
The contact-making surface of auxilliary thimble bottom of described gap gas and described thimble groove is provided with second sealing ring (preventing that Compressed Gas from leaking) that is used for sealing gas.
The beneficial effects of the utility model are: there is the gap in the thimble groove that gas auxilliary thimble in gap of the present utility model is processed into the middle part with mold cores, Wai Bu Compressed Gas can be entered in this gap by gas passage like this, the moment Compressed Gas that is ejected when the auxilliary thimble of gap gas imports product rapidly and ejects between face and mold cores from the gap, remove the vacuum state that product ejects face, can make the smooth ejection device of product, alleviate the distortion that product causes because of ejecting force is excessive greatly.
Description of drawings
View when Fig. 1 does not eject for the auxilliary thimble of gap described in the utility model gas;
View when Fig. 2 ejects for the auxilliary thimble of gap described in the utility model gas.
The specific embodiment
Embodiment: a kind of die clearance gas is assisted ejector pin mechanism, mold cores 1 middle part offers the thimble groove of up/down perforation, be interspersed with gas auxilliary thimble 2 in gap in the thimble groove, gas auxilliary thimble upper end diameter in described gap is greater than its middle part diameter, there is gap 3 between auxilliary thimble middle part outer surface of described gap gas and described thimble groove inner surface, its upper end did not fit tightly with thimble groove inner surface when gas auxilliary thimble 2 in described gap ejected, be provided with gas passage 4 in the described mold cores, described gas passage one end communicates with described gap 3 with exterior and its other end, external compression gas can feed from described gas passage, gas auxilliary thimble 2 lower diameter in described gap are greater than its middle part diameter, auxilliary thimble bottom of described gap gas and described thimble groove fit tightly, described gas passage 4 when gas auxilliary thimble 2 in described gap ejects, described gap 3 and product 5 eject the face three and communicate.There is the gap in the thimble groove that gas auxilliary thimble in gap of the present utility model is processed into the middle part with mold cores, Wai Bu Compressed Gas can be entered in this gap by gas passage like this, the moment Compressed Gas that is ejected when the auxilliary thimble of gap gas imports product rapidly and ejects between face and mold cores from the gap, remove the vacuum state that product ejects face, can make the smooth ejection device of product, alleviate the distortion that product causes because of ejecting force is excessive greatly.
The contact-making surface of described gas passage 4 and mold cores 1 is provided with first sealing ring 6 (preventing that Compressed Gas from leaking) that is used for sealing gas.
The contact-making surface of auxilliary thimble 2 bottoms of described gap gas and described thimble groove is provided with second sealing ring 7 (preventing that Compressed Gas from leaking) that is used for sealing gas.
Use of the present utility model is as follows:
Outside Compressed Gas is entered in the gap between gap gas auxilliary thimble middle part and described thimble groove by gas passage, the moment Compressed Gas that is ejected when the auxilliary thimble of gap gas imports product rapidly and ejects between face and mold cores from the gap, remove the vacuum state that product ejects face, can make the smooth ejection device of product.
