Further, first slider and second slider both sides are equipped with the recess respectively, slider linkage piece is located in the recess of first slider and second slider both sides, first slider stopper is located slider linkage piece one end and fixed connection first slider, second slider stopper is located the slider linkage piece other end and sliding connection the second slider.
Because the utility model discloses the plastic mould of the built-in slide wedge structure of loosing core has adopted above-mentioned technical scheme, this plastic mould's oblique guide pillar slope penetrates first slider promptly, the slider is gone into sub-rear end and is passed through the bolt fastening in first slider, the second slider is equipped with along the axial and holds the chamber, perpendicular axial is equipped with and link up the jack that holds the chamber, the slider is gone into sub-front end and is located the intracavity that holds of second slider, the slide wedge is located the slider and is gone into the inclined hole of son, the slide wedge guide block inserts the jack of second slider and supports and lean on to the slide wedge, first slider and second slider both sides are located and connect first slider and second slider to the slider linkage block is located respectively to first slider stopper and second slider stopper, and first slider is connected to first slider stopper, the second slider is connected to the second slider stopper. The plastic mold overcomes the defect that the traditional plastic mold has a buckle or an undercut position to demold plastic products, realizes core-pulling demolding in different directions through the sliding block, has a simple structure, reduces the mold manufacturing cost, ensures the precision of the products, improves the production efficiency, and more effectively reduces the equipment and labor cost.
Drawings
The invention will be described in further detail with reference to the following drawings and embodiments:
FIG. 1 is a schematic view of a plastic mold with a slide block built-in wedge core-pulling structure according to the present invention;
FIG. 2 is a sectional view of the plastic mold;
fig. 3 is an exploded view of the plastic mold.
Detailed Description
The embodiment is shown in fig. 1, fig. 2 and fig. 3, the plastic mold of the slide block built-in slide wedge core pulling structure of the present invention comprises a slide guide pillar 1, a first slide block 2, a second slide block 3, a slide block insert 4, a slide wedge 5, a slide block linkage block 6, a first slide block stopper 7, a second slide block stopper 8 and a slide wedge guide block 9, wherein the slide guide pillar 1 obliquely penetrates into the first slide block 2, the rear end of the slide block insert 4 is fixed inside the first slide block 2 by a bolt, the second slide block 3 is axially provided with a receiving cavity, a plug hole 31 penetrating through the receiving cavity is vertically axially provided, the front end of the slide block insert 3 is located in the receiving cavity of the second slide block 3, the slide block insert is provided with a slide hole, the slide wedge 5 is provided in the slide block insert 4, the slide wedge guide block 9 is inserted into the plug hole 31 of the second slide block 3 and is abutted against the slide wedge 5, slider linkage piece 6 is located first slider 2 and 3 both sides of second slider and connect first slider 2 and second slider 3, first slider stopper 7 and second slider stopper 8 are located respectively 6 both ends of slider linkage piece to first slider stopper 7 is connected first slider 2, second slider stopper 8 is connected second slider 3.
Preferably, grooves 21 and 32 are formed in two sides of the first sliding block 2 and two sides of the second sliding block 3 respectively, the sliding block linkage block 6 is arranged in the grooves 21 and 32 in two sides of the first sliding block 2 and two sides of the second sliding block 3, the first sliding block limiting block 7 is arranged at one end of the sliding block linkage block 6 and fixedly connected with the first sliding block 2, and the second sliding block limiting block 8 is arranged at the other end of the sliding block linkage block 6 and slidably connected with the second sliding block 3.
As shown in fig. 3, slider linkage block 6 and slider stopper 7, 8 are installed in the both sides of first slider 2 and second slider 3 in this plastic mould, and slide wedge guide block 9 passes in slide wedge 5 according to buckle demolding direction on the slide wedge 5, and slide wedge 5 works out the angle according to the stroke that the 10 buckle drawing of patterns of plastic products needs and adorns in the inclined hole of slider income sub 4 after, and slide wedge 5 and slide wedge guide block 9 are fixed in second slider 3, and slider income sub 4 adopts the bolt fastening in first slider 2. After the injection molding is finished, the inclined guide post 1 moves according to the mold opening direction, at the moment, the first slide block 2 and the slide block insert 4 are driven by the inclined guide post 1 to be parallel to the track of one direction of the plastic product 10 for demolding, due to the action of the second slide block limiting block 8, the second slide block 3 does not move, the inclined wedge 5 moves according to the demolding direction of the plastic product 10 for buckling in different directions under the action of the inclined hole of the slide block insert 4 and the inclined wedge guide block 9, when the first slide block 2 and the slide block insert 4 move to the distance that the inclined wedge 5 is enough to be out of the plastic product 10 for buckling, the second slide block limiting block 8 moves to the limit position of the second slide block 3, namely, a sliding groove is arranged in a groove of the second slide block 3, the second slide block limiting block 8 moves to the tail end position of the sliding groove in the sliding groove, at the moment, the first slide block 2 and the slide block insert 4 do not move independently, but pass through the slide block linkage blocks 6 arranged at two sides of the first slide block 2 and the second slide block 3, the second sliding block 3 and the wedge 5 are driven together to move out of the required core-pulling distance in parallel, so that the plastic product 10 can be buckled in different directions to complete the demoulding action.
The plastic mold can complete the core pulling work in multiple directions at one time, the mold manufacturing cost is reduced, the equipment and labor cost are effectively reduced, the complexity of the mold structure is simplified, the mold opening, core pulling and demolding processes are realized through pure mechanical transmission, and the manufacturing cost is reduced. Practical production shows that the plastic mould has good transmission stability, the precision of the buckle position of the produced plastic product is far higher than that of secondary processing and external core pulling, the qualification rate of the plastic product is improved, the injection molding period is shortened, and the production efficiency is improved.
