In order to better illustrate the present invention, the present invention is described in further detail below with reference to fig. 1-5.
As a specific embodiment of the invention, as shown in fig. 2, an injection mold for a central control side plate of an automobile thin wall, wherein, as shown in fig. 1, the central control side plate 01 of the automobile thin wall comprises a side plate body 011, a long surrounding edge 012 and a short surrounding edge 013 which are arranged at the edges of the side plate body 011, and rib positions 014 which are arranged on the side plate body 011, wherein, the long surrounding edge 012, the short surrounding edge 013 and carry are all provided with buckling positions 015. The injection mold includes:
front template 1, rear template 2 and ejector plate (not shown in the figure);
a front forming area 11 is arranged on the front template 1;
a rear forming area 21 is arranged on the rear template 2, and the front template 1 and the rear template 2 are closed between the front forming area 11 and the rear forming area 21 to form a forming cavity; the rear template 2 is also provided with a first groove 22a, a first sliding block 23a and a first straight top block;
the first groove 22a is arranged at the edge of the rear forming area 21 and is used for forming a long surrounding edge 012 of the automobile thin-wall central control side plate 01;
the first slider 23a is disposed outside the first groove 22a, and has a length corresponding to the length of the first groove 22a; as shown in fig. 3, the first slider 23a is provided with a first protrusion 231a, and the first protrusion 231a is used for forming a buckling position 015 on the long surrounding edge 012; when the mold is opened, the first sliding block 23a slides along the inclined guide pillar connected to the front mold plate 1 to be far away from the molding cavity;
a positioning boss 27 is further arranged on the rear template, and the positioning boss 27 is used for being in plug-in fit with the positioning groove 13 on the front template; the positioning bosses 27 are distributed along the length of the rear molding zone 21.
The first straight ejector block is disposed inside the first groove 22a, and is connected to the ejector plate through a straight ejector rod.
Compared with the injection mold in the prior art that each buckling position 015 is separately provided with a corresponding sliding block, the first sliding block 23a in the injection mold contacts with the whole peripheral edge of the automobile thin-wall central control side plate 01, the contact area is larger, and the contact area between the first protrusion 231a on the first sliding block 23a and the automobile thin-wall central control side plate 01 is further increased, so that the vacuum state between the first sliding block 23a and the automobile thin-wall central control side plate 01 is still reserved at the moment of outward movement, and the inner side of the peripheral edge is further separated from the rear template 2. And the first straight top block is arranged on the inner side of the first groove 22a, so that the automobile thin-wall central control side plate 01 and the rear template 2 are further separated. Therefore, the phenomenon of white top and penetrating top caused by overlarge holding force between the surrounding edge of the automobile thin-wall central control side plate 01 and the rear template 2 can be avoided.
The front template 1 and the rear template 2 of the injection mold are also positioned by utilizing the insertion fit of the positioning groove 13 and the positioning boss 27, so that the front template 1 and the rear template 2 are prevented from being offset due to overlarge injection pressure of the automobile thin-wall central control side plate 01 in the injection molding process, and the phenomenon that the automobile thin-wall central control side plate 01 is in a burr is avoided.
For the short peripheral edge 013 on the automobile thin-wall central control side plate 01, a second groove 22b and a second sliding block 22a are further arranged on the rear template 2; the second groove 22b is arranged at the edge of the rear forming area 21 and is used for forming a short surrounding edge 013 of the automobile thin-wall central control side plate 01; the second slider 22a is disposed outside the second groove 22b, and has a length corresponding to the length of the second groove 22 b; the second slider 22a is provided with a second protrusion 231b, and the second protrusion 231b is used for forming a fastening position 015 on the short peripheral edge 013. When the mold is opened, the first slider 23a slides along the oblique guide post connected to the front mold plate 1 to be away from the molding cavity.
The length of the second sliding block 22a adopted by the injection mold is equal to the length of the short surrounding edge 013, the contact area between the second sliding block 22a and the short surrounding edge 013 is increased, and the short surrounding edge 013 is driven to be separated from the rear mold by utilizing the vacuum state between the second sliding block 22a and the short surrounding edge 013 at the moment of being pulled out.
For the rib position 014 on the automobile thin-wall central control side plate 01, a third groove 22c, an inclined jacking block 25 and a second straight jacking block 24b are further arranged on the rear template 2; the third groove 22c is arranged in the rear forming area 21 and is used for forming a rib position 014 of the automobile thin-wall central control side plate 01; the inclined top block 25 is disposed at one side of the third groove 22c, and the second straight top block 24b is disposed at the other side of the third groove 22 c; the oblique top block 25 is provided with a third protrusion for forming the fastening portion 015 on the rib portion 014. The second straight ejector block 24b is connected to the ejector plate through a straight ejector rod, and the inclined ejector is connected to the ejector plate through an inclined ejector rod and an inclined ejector seat.
The second straight jacking block 24b is disposed on the side surface of the third groove 22c, so that the rib position 014 and the rear template 2 do not have a hugging force during ejection, and the phenomenon that the side plate body 011 is white in top and is penetrated due to the excessive hugging force is avoided.
The rear die plate 2 is further provided with a third straight top block 24c, and the third straight top block 24c is disposed in the rear forming area 21 and is used for propping against the side plate body 011 of the automobile thin-wall central control side plate 01. The third straight ejection block 24c is used for assisting ejection of the automobile thin-wall central control side plate 01, and is arranged opposite to the position without the rib position on the side plate body 011. The third straight ejector block 23c is connected to the ejector plate through a straight ejector rod.
As shown in fig. 4, a ring-shaped groove 26 is further provided in the rear forming area 21, and is used for forming a positioning ring 016 on the thin-walled central control side plate 01 of the automobile.
The injection mold further comprises a plurality of ejector pins 4, and the ejector pins 4 are connected to the ejector pin plate; the thimble 4 is opposite to the area surrounded by the ring-shaped groove 26.
Due to the arrangement of the ring-shaped groove 26, the convex positioning ring 016 is formed on the automobile thin-wall central control side plate 01, and the thimble 4 cannot shift in the ejection process, so that the phenomenon that the thimble 4 transversely moves along the side plate body 011 to carry out glue shoveling is avoided.
The end face of the thimble 4 is provided with concave-convex characteristics 41, and the concave-convex characteristics 41 are used for forming concave-convex patterns 7 on the automobile thin-wall central control side plate 01. Because the automobile thin-wall central control side plate 01 is provided with the concave-convex patterns 7, the strength of the automobile thin-wall central control side plate at the contact part with the thimble 4 is enhanced, and the thimble 4 can be further prevented from penetrating through the side plate body 011.
As shown in fig. 5, a ring of vent inserts 12 is disposed around the front molding zone 11. Because the thin-wall product is easy to generate the phenomenon of trapping air after being molded, air lines can appear on the surface of the product, thereby influencing the appearance of the product. Therefore, the exhaust insert 12 is required to be used for exhaust in the injection molding process, and air in the molding cavity is rapidly exhausted from the exhaust insert 12 in all directions along with the injection of the sizing material into the molding cavity, so that the phenomenon of air trapping is avoided.
The ejection principle of the injection mold of the thin-wall central control side plate of the automobile is as follows:
the injection molding machine is opened, the first slider 23a and the second slider 22a move along with the front mold plate 1, move away from the molding cavity, and take the long surrounding edge 012 and the short surrounding edge 013 away from the rear mold plate 2 at the moment of starting the movement. Then the first slide block 23a and the second slide block 22a are separated from the long surrounding edge 012 and the short surrounding edge 013 under the tensile force of the side plate body 011 on the long surrounding edge 012 and the short surrounding edge 013;
the inclined ejector block 25 and the straight ejector block are ejected out towards the direction of the front template 1 under the drive of the ejector plate, so that the automobile thin-wall central control side plate 01 is ejected out.
