Abstract
The utility model discloses a mechanism for removing slide blocks of an injection mold from inverted clampers. The mechanism is provided with a main slide block and a secondary slide block, wherein the secondary slide block is positioned on the upper surface of the main slide block. The main slide block is provided with a first groove for molding a first inverted clamper of a product. The secondary slide block is provided with a second groove for molding a second inverted clamper of the product. The main slide block is provided with a first oblique guide slot, the upper end of the slide block beam block is fixed on a female mold, and the guide section of the slide block beam block is inserted into the first oblique guide slot and a gap is formed between the guide section and the outer side wall of the first oblique guide slot during mold closing. The secondary slide block is provided with a second oblique guide slot, an oblique guide column is fixed on the female mold, and the oblique guide column is inserted into the second oblique guide slot and presses against the outer side wall of the second oblique guide slot during mold closing. When the mold is opened, the secondary slide block is separated from the second inverted clamper by matching of the second oblique guide slot and the oblique guide column, the main slide block is separated from the first inverted clamper by matching of the first oblique guide slot and the slide block beam block, and then the product is ejected upwards through an ejection mechanism to achieve complete separation of the product and the mold.
Description
Technical field
The utility model belongs to the injection mold structure field, is specifically related to a kind of slide block mechanism that can realize the demoulding of different directions back-off.
Background technology
Some plastic product need to be at its circular hole place or side-walls mold back-off structure for cooperating with other products, the injection mold of general product for being manufactured with back-off all has slide block, and the Main Function that slide block plays is to mold back-off and deviate from back-off when moulding when the demoulding.But only have single slide block in the injection mold of prior art, single slide block can only be deviate from unidirectional back-off, can't directly make the complete demoulding of product.
The utility model content
In order to overcome defects, the utility model provides a kind of slide block of injection mold to take off back-off mechanism, and the slide block of injection mold of the present utility model takes off back-off mechanism can make the up and down smooth demoulding of back-off of two kinds of different directions, and simple in structure, easy to implement.
The utility model for the technical scheme that solves its technical problem and adopt is:
A kind of slide block of injection mold takes off back-off mechanism, be provided with master slider and time slide block, described time slide block is positioned at described master slider upper surface, has the first groove for shaped article the first back-off on the described master slider, has the second groove for shaped article the second back-off on described slide block, offer the first inclined guide groove on the described master slider, described the first inclined guide groove oblique is from inside to outside inclination from top to bottom, be provided with slide block bundle piece, master mold is fixed in described slide block bundle piece upper end, described slide block bundle piece has the guide section consistent with described the first inclined guide groove gradient, described guide section can be inserted in described the first inclined guide groove, and the width of described the first inclined guide groove is greater than the width of described guide section, during matched moulds the guide section of described slide block bundle piece insert in described the first inclined guide groove and and the lateral wall of the first inclined guide groove between have the gap, offer the second inclined guide groove on described the slide block, described the second inclined guide groove oblique is from inside to outside inclination from top to bottom, be provided with Angle Pin, oblique and described second inclined guide groove of described Angle Pin oblique consistent, master mold is fixed in described Angle Pin upper end, described Angle Pin can be inserted in described the second inclined guide groove, and described Angle Pin is inserted in described the second inclined guide groove and against the lateral wall of described the second inclined guide groove during matched moulds.
The beneficial effects of the utility model are: the utility model has designed master slider and time slide block for the back-off of two kinds of different directions of product, master slider has different strokes with time slide block, during die sinking, master mold moves upward and drives Angle Pin and the slide block bundle piece be fixed on the master mold and upwards extract, time slide block was realized the disengaging of time slide block and the second back-off by the second gathering sill on time slide block and the interference engagement between the Angle Pin before this, along with master mold continue move upward, master slider is realized the disengaging of master slider and the first back-off by the interference engagement of the first inclined guide groove and slide block bundle piece, product upwards ejects by ejecting mechanism again, to realize the complete demoulding of product.
Description of drawings
Fig. 1 is the profile of the utility model after moulding and before the die sinking;
Fig. 2 be the utility model after the first back-off demoulding and the second back-off begin the profile of demoulding state;
Fig. 3 is that the utility model is at the profile of the first back-off and the second back-off demoulding completion status.
The specific embodiment
Embodiment: a kind of slide block of injection mold takes off back-off mechanism, be provided with master slider 1 and time slide block 2, described time slide block 2 is positioned at described master slider 1 upper surface, has the first groove 11 for the first back-off A1 of shaped article A on the described master slider 1, has the second groove 21 for the second back-off A2 of shaped article A on described slide block 2, offer the first inclined guide groove 12 on the described master slider 1, described the first inclined guide groove 12 oblique is from inside to outside inclination from top to bottom, be provided with slide block bundle piece 3, master mold 4 is fixed in described slide block bundle piece upper end, described slide block bundle piece 3 has the guide section 31 consistent with described the first inclined guide groove gradient, described guide section 31 can be inserted in described the first inclined guide groove 12, and the width of described the first inclined guide groove 12 is greater than the width of described guide section 31, during matched moulds the guide section 31 of described slide block bundle piece insert in described the first inclined guide groove 12 and and the lateral wall of the first inclined guide groove between have the gap, offer the second inclined guide groove 22 on described the slide block 2, described the second inclined guide groove 22 oblique is from inside to outside inclination from top to bottom, be provided with Angle Pin 5, oblique and described second inclined guide groove of described Angle Pin oblique consistent, master mold 4 is fixed in described Angle Pin 5 upper ends, described Angle Pin 5 can be inserted in described the second inclined guide groove 22, and described Angle Pin is inserted in described the second inclined guide groove and against the lateral wall of described the second inclined guide groove during matched moulds.
