The outer surface of the combined positive mold, the inner surface of the side compression mold, and the cavity groove of the boss are combined to form a multi-directional joint molding cavity. The outer side wall of the side compression mold is set at an angle with the plane of the base plate, and a pressure transmission outer mold is provided outside the side compression mold. The composite multi-directional joint is prepared by using the above-mentioned integral compression molding die.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Example 1: Please refer to Figure 1-Figure 6 The utility model provides the following technical solution: a one-mold multi-cavity composite material integral molding device with inserts, comprising a cover plate 1, a first threaded hole 2 and a fourth positioning hole 17.

[0027] A first threaded hole 2 is provided at the top of the cover plate 1, and a sliding nesting mechanism for fixing the movable template 4 is installed inside the first threaded hole 2, the sliding nesting mechanism includes a screw 3, and the screw 3 is nested inside the first threaded hole 2, the inner surface of the first threaded hole 2 is threaded, and a movable template 4 is installed below the cover plate 1, a second threaded hole 9 is provided above the movable template 4, and the inner surface of the second threaded hole 9 is threaded, the opening position of the second threaded hole 9 corresponds to the installation position of the screw 3, and the screw 3 is nested inside the second threaded hole 9, a first positioning hole 7 is provided at the top of the movable template 4, and a first positioning pin 8 is installed inside the first positioning hole 7, a movable mold shaft hole 10 is provided at the top of the movable template 4, and a nested movable mold shaft 11 is installed inside the movable mold shaft hole 10;

[0028] A nested movable mold shaft 11 is installed inside the movable mold shaft hole 10 , and a nested sliding mechanism for nesting and installing the ejection nesting rod 16 is installed on the outer surface of the nested movable mold shaft 11 .

[0029] like Figure 2 , Figure 3 , Figure 4The technical solution shown, in order to solve the problem that it is inconvenient to perform manual maintenance in the event of a malfunction, discloses: the screw 3 passes through the interior of the cover plate 1 as a whole, and four groups of screws 3 are evenly installed about the center point of the cover plate 1, and the cover plate 1 is fixedly connected to the movable template 4 by the screw 3, the cover plate 1 and the movable template 4 have the same size, and the outer surface of the first positioning hole 7 contacts the outer surface of the first positioning pin 8 to form a sliding structure, and the inner surfaces of the first threaded hole 2 and the second threaded hole 9 are both threaded, the inner surface of the movable mold shaft hole 10 contacts the outer surface of the nested movable mold shaft 11 to form a sliding structure, and the first positioning hole 7 and the first positioning pin 8 are installed corresponding to each other, and the first positioning hole 7 and the first positioning pin 8 are evenly installed in four groups about the center point of the cover plate 1, and the screw 3, the first positioning pin 8 and the nested movable mold shaft 11 are all countersunk designs.

[0030] When the upper end of the equipment needs to be nested and molded, first use the screw 3 to rotate along the first threaded hole 2 opened on the top of the cover plate 1. Since the interior of the first threaded hole 2 is a threaded design and a through hole design, the screw 3 passes through the cover plate 1 as it rotates. After the screw 3 completely passes through the inside of the cover plate 1, it contacts the movable template 4, and the screw 3 enters the second threaded hole 9 opened on the top of the movable template 4. Since the interior of the second threaded hole 9 is also a threaded design, as the screw 3 enters the second threaded hole 9, it continues to rotate. The screw 3 is completely nested and installed with the second threaded hole 9, and the cover plate 1 should be screwed 3. It forms a fixed connection with the movable template 4. When the bottom surface of the cover plate 1 contacts the top of the movable template 4, it also contacts the nested movable mold shaft 11. Since the nested movable mold shaft 11 is nested inside the movable mold shaft hole 10 opened at the top of the movable template 4, the installation is completed more stably as the cover plate 1 is fixed above the nested movable mold shaft 11 is resisted. At the same time, the cover plate 1 also resists the first positioning pin 8. The first positioning pin 8 is more precisely nested inside the first positioning hole 7, and the first positioning pin 8 completely passes through the interior of the movable template 4 until it enters the second positioning hole 13 opened at the top of the fixed mold 5 to complete the nested installation.

[0031] like Figure 2 , Figure 3 , Figure 4The technical solution shown in the figure, in order to solve the problem that it is inconvenient to perform maintenance manually when a fault occurs, discloses: the nested sliding mechanism includes a fixed mold 5, and the fixed mold 5 is installed on the lower surface of the movable mold plate 4, a finished mold 12 is opened on the top of the fixed mold 5, and the nested movable mold shaft 11 is correspondingly installed inside the finished mold 12, a second positioning hole 13 is opened on the top of the fixed mold 5, and the opening position of the second positioning hole 13 corresponds to the installation position of the first positioning pin 8, the first positioning pin 8 enters the second positioning hole 13 again after passing through the inside of the movable mold plate 4, and a top plate 6 is installed on the lower surface of the fixed mold 5, and a third positioning hole 13 is opened on the lower surface of the top plate 6 Positioning hole 14, a second positioning pin 15 is installed inside the third positioning hole 14, and the second positioning pin 15 passes through the third positioning hole 14 as a whole, a fourth positioning hole 17 is opened on the lower surface of the fixed mold 5, and the opening position of the fourth positioning hole 17 corresponds to the installation position of the second positioning pin 15, an ejection interlocking rod 16 is installed above the top plate 6, and the ejection interlocking rod 16 corresponds to the opening position of the finished mold 12, the outer surface of the finished mold 12 contacts the outer surface of the ejection interlocking rod 16 to form a sliding structure, and the outer surface of the second positioning pin 15 contacts the inner surface of the fourth positioning hole 17 to form a sliding structure.

[0032] When the first locating pin 8 enters the second locating hole 13, the nested movable mold shaft 11 nested in the movable mold shaft hole 10 also contacts the fixed mold 5 at the same time, and with the continued downward movement, the nested movable mold shaft 11 enters the finished mold 12 opened at the corresponding position on the top of the fixed mold 5. Since the finished mold 12 is a through-hole design, the nested movable mold shaft 11 blocks the upper end opening of the finished mold 12 to form a semi-open state. In order to ensure the smooth formation of the mold, a top plate 6 is installed on the lower surface of the fixed mold 5. In order to ensure that the finished mold 12 can form a completely enclosed molding space, the installation of the top plate 6 is fixed using the second locating pin 15 installed in the third locating hole 14 opened on the lower surface. The third positioning hole 14 is a through hole design, so the second positioning pin 15 continues to slide upward after passing through the third positioning hole 14 until it contacts the fixed mold 5. The second positioning pin 15 continues to move upward and enters the fourth positioning hole 17 opened at the corresponding position on the lower surface of the fixed mold 5 until it reaches the limit position to complete the nested and fixed movement of the fixed mold 5 and the top plate 6. While the top plate 6 moves upward, the ejection engaging rod 16 fixedly installed on the upper surface of the top plate 6 also moves synchronously therewith, and enters the lower end opening of the finished mold 12 to form a completely enclosed molding space for the finished mold 12. Since the nested movable mold shaft 11 is a through-type design, the raw material is transported through the nested movable mold shaft 11 to complete the cooling and compression molding.
