The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further details.
As shown in Figure 1, Figure 2, Figure 3 shows, the utility model embodiment comprises that pressing plate 11, the oil cylinder 12 as linear drives part, wedge 13, barb form piece 14, sliding shoe 15.
As shown in Figure 3, the applied injection mold of the utility model embodiment comprise die cavity 2 and moving platen 3, the lower compound plate 9 of mutual correspondence and be located at mould pin 5 between lower compound plate 9 and moving platen 3, between moving platen 3 and lower compound plate 9 mobile ejector retainner plate 7 and thimble compound plate 8, be located at the push rod 6 on ejector retainner plate 7.Separately as shown in Figure 1 and Figure 2, the oil cylinder 12 of the utility model embodiment is fixed on an oil cylinder seat 122,122 of oil cylinder seats are arranged on the side of the moving platen 3 of injection mold, the barb that barb forms piece 14 sides forms the barb that structure 141 is mainly used in forming plastic cement products, and barb forms piece 14 and coordinates the barb that makes its barb form structure 141 and plastic cement products to be easy to depart from oil cylinder 12, wedge 13, sliding shoe 15.
As shown in Figure 1, Figure 2, Figure 3 shows, the oil cylinder 12 for linear movement output is fixed on its oil cylinder seat 122,122 sides of being fixed on moving platen 3 by parts such as screws of oil cylinder seat.
As Figure 1-Figure 4, the rear end of wedge 13 is connected on pressing plate 11, to carry out linear reciprocating motion with the piston rod 121 of oil cylinder 12.The side of moving platen 3 is provided with the through hole 30 extending inward, through hole 30 extends to the inside of moving platen 3, wedge 30 is located in through hole 30 slidably, and the upper surface of wedge 13 is provided with cross section along its length direction and is the first T-shaped groove 133, and wedge 13 upper surface leading portions are downward-sloping inclined plane 132.
As shown in Figure 1, Figure 2, Figure 6 shows, sliding shoe 15 lower surfaces are provided with that cross section is T-shaped and the first raised line 151, the first raised lines 151 of being obliquely installed embed in the first groove 133 slidably; One vertical side of sliding shoe 15 is provided with the second groove 152 that cross section is T-shaped and is obliquely installed, when wedge 13 moves along linear reciprocation, the first groove 133 of wedge 13 drives the first raised line 151 to move thereupon, and sliding shoe 15 is pumped.
As shown in Figure 1, Figure 2, Figure 5, barb forms the vertical side of piece 14 1 and is provided with the second raised line 142 that cross section is T-shaped and is obliquely installed, another vertical side is provided with the barb that is used to form plastic cement products barb and forms structure 141, the second raised lines 142 and embed slidably in the second groove 152.When sliding shoe 15 pumps, the second groove 152 drives the second raised line 142 to do horizontal shifting, makes barb form piece 14 and does front-rear reciprocation movement.
