[0025] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings.

[0026] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions in the embodiments may be combined with each other.

[0027] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0028] Example 1 Please refer to Figure 1 and Figure 2 As shown, a longitudinal beam trimming mold with a pressure plate fixing guide sleeve comprises a lower mold plate 1, an upper mold outer plate 2, a lower mold outer plate 11, and an upper mold plate 3. The surfaces of the lower mold plate 1 and the lower mold outer plate 11 at both ends are symmetrically provided with mounting holes, and the internal threads of the mounting holes are connected with mounting threads 13. Guide columns 18 are installed on both sides of the upper surface of the lower mold plate 1, the upper mold outer plate 2 is slidably connected with the upper mold plate 3, and limiting parts are installed on both ends of the guide columns 18. A pressure supply part is installed on the top side of the lower mold outer plate 11, and a trimming part is installed on one side of the pressure supply part. A guide cylinder 22 is installed on the top of the upper mold outer plate 2, and external grooves 27 are provided at both ends of the upper mold outer plate 2. Positioning parts are installed on both sides of the two ends of the upper mold outer plate 2. Fixed splints 31 are installed at the bottom of both ends of the upper mold plate 3, and slots are provided on the sides of the fixed splints 31. Pushing parts are connected to the surfaces of the two ends of the fixed splints 31, and a telescopic part is installed at one end of the pushing part. Slide plates 21 are slidably connected to both ends of the upper mold outer plate 2.

[0029] Please refer to Figure 1 , Figure 2 , Figure 7 and Figure 8As shown, the pushing member includes a spring three 51, a slide plate 21 is slidably arranged on the surface of the upper mold outer plate 2, one end of the top of the slider 62 extends to the inside of the placement slot 26 and is slidably connected to the spring three 51, one end of the spring three 51 is provided with a push plate 5, the spring three 51 is fixedly connected to the slider 62, the spring three 51 is matched with the slot on the upper mold plate 3, and the placement slot 26 is connected to the gap formed by the slide plate 21 and the upper mold outer plate 2.

[0030] During the implementation process, in the original state, a gap is formed between the slide plate 21 and the upper mold outer plate 2, and the size of the gap is the same as the width of the bottom of the fixed clamp 31. When the upper mold 3 is inserted into the gap, the slide plate 21 is driven to move, thereby driving the slider 62 to move. The movement of the slider 62 drives the spring three 51 fixedly installed on the top of the slider 62 to squeeze and move the push plate 5 inside the placement slot 26. The push plate 5 is blocked by the upper mold outer plate 2 and will not move. When the slot on the side of the upper mold 3 and the push plate 5 appear on the same horizontal plane, the push plate 5 is inserted into the slot of the fixed clamp 31 to fix the upper mold 3.

[0031] Beneficial effect: the placement slot 26 is located on the external slot 27, and people can operate the push plate 5 externally to replace the upper template 3. As long as the size is the same as the upper template 3 and the lower mold outer plate 11 when the mold is developed, the replacement can be achieved without replacing the entire mold or moving the equipment or the mold as a whole.

[0032] Example 2 The longitudinal beam trimming die of the pressure plate fixing guide sleeve provided in Example 1 is further optimized, specifically, as follows Figure 1 and Figure 2 As shown, the limiting member includes a limiting column 14, which is symmetrically installed at the top of both ends of the lower mold plate 1, and a limiting sleeve 210 is symmetrically installed at both ends of the upper mold outer plate 2.

[0033] When the upper mold outer plate 2 and the upper mold plate 3 move downward to produce the product by injection molding, the closing of the lower mold plate 1 and the upper mold outer plate 2 can be restricted so that the internal structure alignment will not be misaligned.

[0034] Example 3 The longitudinal beam trimming die of the pressure plate fixing guide sleeve provided in Example 1 or 2 is further optimized, specifically, as follows Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 and Fig.10As shown, the telescopic member includes a gear 61, which is meshed with the tooth plate 6, and the two ends of the bottom side of the upper mold outer plate 2 are equipped with an outer cylinder 23. The gear 61 extends to the inside of the outer cylinder 23 and is fixedly installed with a screw 66. The inner wall of the outer cylinder 23 is provided with a first slide groove 25, and the external thread of the screw 66 is connected to the lower column 24, and the lower column 24 is slidably connected with the first slide groove 25.

[0035] Further, such as Figure 2 , Figure 5 , Figure 6 and Fig.10 As shown, the trimming part includes a trimming knife 4, which is L-shaped, with connecting plates 44 installed at both ends of the trimming knife 4, a stretch rod 42 installed at one end of the connecting plate 44, an air cylinder 41 is slidably connected to the outside of one end of the stretch rod 42, and a spring 2 43 is installed on the top side of the connecting plate 44 located on the outside of the stretch rod 42, and the other end of the spring 2 43 is fixedly installed with the air cylinder 41, connecting holes 28 are opened at both ends of the bottom side of the lower template 1, and second slide grooves 29 are symmetrically opened on both sides of the inner wall of the upper template 3, the trimming knife 4 is arranged inside the second slide groove 29, and the air cylinder 41, the connecting plate 44, the spring 2 43, and the stretch rod 42 are arranged inside the connecting hole 28.

[0036] Further, such as Figure 3 and Figure 4 As shown, the pressure supply member includes a vent pipe 12, a movable groove 17 is formed inside one end of the vent pipe 12, a spring 16 is installed inside the movable groove 17, and an air supply column 15 is installed inside the spring 16.

[0037] Further, such as Figure 7 and Figure 8 As shown, movable grooves 64 are opened inside at both ends of the upper mold outer plate 2, and a tooth plate 6 is installed inside the movable groove 64 at the bottom of one end of the slide plate 21, and a slider 62 is installed on the top side of the tooth plate 6. The slider 62 and the tooth plate 6 are respectively fixed to the upper and lower surfaces of the slide plate 21, and a fourth spring 63 is installed at one end of the slider 62, and the fourth spring 63 is fixed to the movable groove 64. A third sliding groove 65 is opened on the top of the movable groove 64, and the slider 62 is slidably connected to the third sliding groove 65.

[0038] During the implementation process, when the upper mold plate 3 is fixed, the slider 62 moves together with the toothed plate 6, thereby driving the gear 61 to rotate. The rotation of the gear 61 drives the screw 66 inside the outer cylinder 23 to rotate. The screw 66 drives the lower moving column 24 threadedly connected on the outer surface to slide downward inside the first slide groove 25 and extend a certain length. When the lower mold plate 1 and the upper mold outer plate 2 are closed, the connecting hole 28 is first connected to the ventilation pipe 12 and then the lower moving column 24 squeezes the air supply column 15, so that it can squeeze the air supply column 15 inside the ventilation pipe 12 to supply air. The column 15 will first squeeze the spring 16 inside the movable groove 17, and then the distance that the air supply column 15 moves in the movable groove 17 will generate pressure, which will be transported to the connecting hole 28 through the ventilation pipe 12. The air cylinder 41 installed in the connecting hole 28 provides pressure to the extension rod 42 to make it extend from the inside of the air cylinder 41 and push the trimming knife 4 to move to the second slide groove 29 through the connecting plate 44. When the lower mold plate 1 and the upper mold outer plate 2 are separated, the trimming knife 4 returns to its original position under the action of the spring 2 43 to trim the remaining edges and corners of the injection-molded longitudinal beam.

[0039] The use process of the longitudinal beam trimming die for fixing the guide sleeve of the pressure plate provided by the present invention is as follows: During installation, the lower mold outer plate 11 is placed on the inner bottom of the lower mold plate 1, and is replaced and fixed by installing the thread 13 and the mounting hole on the lower mold outer plate 11. In the original state, a gap is formed between the slide plate 21 and the upper mold outer plate 2. The size of the gap is the same as the width of the bottom of the fixed clamping plate 31. When the upper mold plate 3 is inserted into the gap, the slide plate 21 is driven to move, thereby driving the slider 62 to move. The movement of the slider 62 drives the spring 3 51 fixedly installed on the top of the slider 62 to squeeze and move the push plate 5 inside the placement slot 26. The push plate 5 is blocked by the upper mold outer plate 2 and does not move. When the notch on the side of the upper mold plate 3 and the push plate 5 appear on the same horizontal plane, the push plate 5 is inserted into the notch of the fixed clamping plate 31 to fix the upper mold plate 3, and the slider 62 moves with the tooth plate 6, thereby driving the gear 61 to rotate. The rotation of the gear 61 drives the screw 66 inside the outer cylinder 23 to rotate, and the screw 66 drives the lower moving column 24 with a threaded connection on the outer surface to slide downward and extend a certain length inside the first slide groove 25. When the mold is closed, the upper mold outer plate 2 and the upper mold plate 3 move downward to produce products by injection molding, and the lower mold plate 1 and the upper mold outer plate 2 can be moved downward. The closure is restricted so that the internal structure is aligned and does not misalign. The connecting hole 28 is first connected to the vent pipe 12, and then the lower column 24 squeezes the air supply column 15, so that it can squeeze the air supply column 15 inside the vent pipe 12. The air supply column 15 will first squeeze the spring 16 inside the movable groove 17, and then the distance the air supply column 15 moves in the movable groove 17 will generate pressure, which is transported to the connecting hole 28 through the vent pipe 12, and the air cylinder 41 installed in the connecting hole 28 provides pressure to the extension rod 42 so that it extends from the inside of the air cylinder 41 and pushes the repair through the connecting plate 44. The trimming knife 4 moves to the second slide groove 29. When the lower template 1 and the upper mold outer plate 2 are separated, the trimming knife 4 returns to its original position under the action of the second spring 43 to trim the remaining corners of the injection-molded longitudinal beam. When the mold needs to be replaced, the push plate 5 is pulled toward the side away from the fixed clamping plate 31 to squeeze the third spring 51, so that the push plate 5 is disengaged from the groove on the side of the fixed clamping plate 31, thereby facilitating the replacement of the upper template 3. The tooth plate 6 and the slider 62 are moved toward the side close to the movable groove 64 under the action of the fourth spring 63, and the slider 62 moves inside the third slide groove 65.
