In order to overcome the not enough of prior art, the utility model provides a slider skew formula structure of loosing core.
The utility model provides a technical scheme that its technical problem adopted is:
the utility model provides a slider skew formula structure of loosing core, includes front mould and back mould, its characterized in that: the large sliding block is in sliding fit with the rear die, the oil hydraulic cylinder is fixed on the rear die, an insert groove and a forming groove are formed in the large sliding block, the insert groove is communicated with the forming groove, a front die insert is arranged in the insert groove, the small sliding block is in sliding fit with the rear die through a guide structure, a protruding block is arranged on the small sliding block and located in the forming groove, the oil hydraulic cylinder is connected with the large sliding block and drives the large sliding block to move, the large sliding block can drive the small sliding block to move along the direction limited by the guide structure by extruding the protruding block through the inner wall of the forming groove, and the width of the forming groove is larger than the length of the protruding block.
The guide structure comprises a T-shaped block arranged at the bottom of the small sliding block and a pressing plate oppositely arranged on the rear die, the sliding groove and the pressing plate form a T-shaped sliding groove, the T-shaped block is in sliding fit with the T-shaped sliding groove, and an included angle is formed between the moving direction of the small sliding block along the T-shaped sliding groove and the moving direction of the large sliding block.
The rear die is provided with a support frame and a sliding groove, the oil hydraulic cylinder is fixed with the support frame, the large sliding block is matched with the sliding groove, and the sliding groove is formed by fixing a large sliding block pressing plate on the rear die.
The utility model has the advantages that: the utility model discloses a big slider of oil hydraulic cylinder drive removes, and the little slider of big slider drive removes, but little slider has the motion track that is different from big slider, realizes that big slider and little slider move and the drawing of patterns according to the equidirectional not, and drive power (hydro-cylinder) of above-mentioned structure realizes two direction drawing of patterns actions to compact structure reliability is high.
Drawings
The present invention will be further explained with reference to the drawings and examples.
Fig. 1 is an exploded view of the present invention;
fig. 2 is a cross-sectional view of the present invention;
fig. 3 is a bottom view of the present invention.
Detailed Description
Referring to fig. 1 to 3, the utility model discloses a slider skew formula structure of loosing core, not demonstrate including front mould (not in the picture) and back mould (not show in the picture), still include oil hydraulic cylinder 1, big slider 2 and little slider 3, big slider 2 and back mould sliding fit, oil hydraulic cylinder 1 is through being fixed in on the back mould, be equipped with insert groove 4 and shaping groove 5 in the big slider 2, insert groove 4 link up with shaping groove 5, be equipped with front mould mold insert 9 in the insert groove 4, little slider 3 is through guide structure and back mould sliding fit, guide structure specifically lies in: the sliding device comprises a T-shaped block 6 arranged at the bottom of a small sliding block 3 and a pressing plate 7 oppositely arranged on a rear die, wherein the rear die and the pressing plate 7 form a T-shaped sliding groove, the T-shaped block 6 is in sliding fit with the T-shaped sliding groove, an included angle is formed between the moving direction of the small sliding block 3 along the T-shaped sliding groove and the moving direction of a large sliding block 2, a convex block 8 is arranged on the small sliding block 3, the convex block 8 is positioned in a forming groove 5, an oil hydraulic cylinder 1 is connected with the large sliding block 2 and drives the large sliding block 2 to move, the large sliding block 2 can drive the small sliding block 3 to move along the direction limited by a guide structure by extruding the convex block 8 through the inner wall of the forming groove 5, the width of the forming groove 5 is larger than the length of the convex block 8, the moving direction of the large sliding block 2 and the moving direction of the small sliding block 3 in the application have included angles on a horizontal plane and a vertical plane, therefore, the structure is adopted, the large sliding block 2 can drive the small sliding block 3 to move along the direction of the T-shaped sliding groove by extruding the convex block 8 through the inner wall of the forming groove 5, sliding friction can be generated between the inner wall of the forming groove 5 and the surface of the convex block 8 in the moving process, so that the large sliding block 2 is ensured to move upwards relative to the small sliding block 3 and drive the small sliding block 3 to move, and the width of the forming groove 5 is larger than the length of the convex block 8, so that the small sliding block 3 is ensured to have an offset space when moving and offset along with different moving directions of the large sliding block 2. In addition, in order to avoid the motion interference of the front mold insert 9 and the large slide block 2, the large slide block 2 needs to be driven by an oil cylinder, the large slide block 2 is closed in place and then is closed, namely the front mold insert 9 is inserted into the large slide block 2, the front mold insert 9 and the front mold are fixed, the process is guaranteed by a travel switch, and the travel switch senses that the large slide block 2 is closed in place and then gives an injection molding machine closing instruction.
