Description

Technical Field

[0001] This utility model relates to molds, and in particular, to a pseudo-three-plate mechanical secondary mold opening injection mold structure. Background Technology

[0002] like Figure 1 As shown, an upper bracket includes a bracket body 90. The back of the bracket body 90 is provided with screw post 1 91, screw post 2 92, buckle 1 93 and buckle 2 94. Screw post 1 91 is vertically arranged, screw post 2 92 is inclined, and screw post 2 92, buckle 1 93 and buckle 2 94 respectively form inverted buckle 1, inverted buckle 2 and inverted buckle 3.

[0003] When designing the mold for the bracket body, it is difficult to remove the first buckle using a general core-pulling structure. Furthermore, the first and second buckles are close to each other, which can easily cause interference when setting the release structure. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a pseudo three-plate mechanical secondary mold opening injection mold structure, which solves the problems in the background technology.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is: a pseudo three-plate mechanical secondary mold opening injection mold structure, including a top plate, an upper mold, a lower mold, an ejector plate, and a bottom plate. A fixing plate is also provided between the bottom plate and the lower mold. The fixing plate is fixedly connected to the lower mold. A guide rod is also provided on the fixing plate. The lower mold is slidably mounted on the guide rod. A first ejector rod is also provided between the lower mold and the ejector plate. A first inclined pull assembly is also provided on the fixing plate. The first inclined pull assembly is used to form a first undercut. A second inclined ejector assembly is also provided inside the lower mold. The second inclined ejector assembly is used to form a second undercut.

[0006] By using the above-mentioned technical means, by setting a fixed plate and setting a slanted pull component one on the fixed plate, the lower mold is ejected after the mold is opened, and the slanted pull component one is driven to complete the core pulling of the undercut one. By setting a slanted ejector component two, the undercut two can be released normally.

[0007] Preferably, the inclined drawing assembly includes an inclined drawing base and an inclined drawing block. The inclined drawing base is fixedly mounted on a fixed plate. A T-shaped drawing block is inclinedly mounted on the inclined drawing base. The inclined drawing block slides and engages with the T-shaped drawing block. The lower mold has an inclined drawing groove for the inclined drawing block to slide. When the ejector plate ejects the lower mold, the inclined drawing block moves inclinedly and disengages from the undercut.

[0008] By employing the aforementioned technical means, the core pulling of the inverted core is completed through the poor fit between the inclined base and the inclined block one. At the same time, the fit between the T-shaped block and the inclined block one ensures that the inclined block one will not fall off.

[0009] Preferably, the side end of the inclined draw base is further provided with an inclined top component three, which is used to form the inverted buckle three. The inclined top component three includes a follower block and a hinge member. The tail of the follower block is hinged to the hinge member. The hinge member is provided on the ejector plate. A limiting inclined surface is provided on the inclined draw base, and the follower block abuts against the limiting inclined surface.

[0010] Through the above-mentioned technical means, the follower block is driven to complete the forming and ejection of the undercut three by the cooperation of the hinge and the follower block. By setting the limiting slope, the follower block is reset when the mold is closed.

[0011] Preferably, the hinge component includes a base, a sliding block, and a hinge block. The base is provided with a sliding groove, the sliding block is slidably disposed in the sliding groove, and the hinge block is hingedly disposed on the sliding block.

[0012] By employing the aforementioned technical means, through the cooperation of the sliding block and the sliding groove, and by hingedly setting the hinge block on the sliding block, the follower block is tilted out, thus completing the core extraction.

[0013] Preferably, the second inclined top component includes a second inclined pull block and a second inclined pull rod. The second inclined pull rod is located at the bottom of the second inclined pull block, and the tail of the second inclined pull rod is also provided with a hinge. The second inclined pull block is used to form the second inverted buckle.

[0014] Through the aforementioned technical means, the forming and release of the inverted buckle are achieved by cooperating with the inclined pull block two and the inclined pull rod.

[0015] Preferably, the fixed plate is further provided with a guide block, and the follower block and the inclined pull rod are both slidably engaged with the guide block. The guide block is provided with an inclined hole for guiding direction.

[0016] By using the above-mentioned technical means, and by setting guide blocks on the fixed plate, it is not necessary to open guide square holes in the lower mold and the fixed plate, thereby reducing production costs.

[0017] Preferably, the lower mold is further provided with a guide protrusion, and the upper mold is provided with a guide groove, wherein the guide protrusion is adapted to the guide groove.

[0018] By employing the aforementioned technical means, the mold closing accuracy is increased through the cooperation between the guide protrusion and the guide groove. Attached Figure Description

[0026] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings, so that the technical solution of this utility model can be more easily understood and mastered.

[0027] A pseudo-three-plate mechanical secondary mold opening injection mold structure includes a top plate 1, an upper mold 2, a lower mold 3, an ejector plate 4, and a bottom plate 5. A fixing plate 6 is also provided between the bottom plate 5 and the lower mold 3, and the fixing plate 6 is fixedly connected to the lower mold 3. A guide rod 7 is also provided on the fixing plate 6, and the lower mold 3 is slidably mounted on the guide rod 7. An ejector rod 8 is also provided between the lower mold 3 and the ejector plate 4. A slanted pull assembly 9 is also provided on the fixing plate 6, which is used to form an undercut. A slanted ejector assembly 10 is also provided inside the lower mold 3, which is used to form an undercut. By setting the fixing plate 6 and the slanted pull assembly 9 on the fixing plate 6, the lower mold 3 is ejected after mold opening, driving the slanted pull assembly 9 to complete the core pulling of the undercut. By setting the slanted ejector assembly 10, the undercut can be normally removed.

[0028] The inclined pull assembly 9 includes an inclined pull base 11 and an inclined pull block 12. The inclined pull base 11 is fixedly mounted on the fixed plate 6. The core pulling of the undercut is completed through the misfit between the inclined pull base 11 and the inclined pull block 12. A T-shaped pull block is inclinedly mounted on the inclined pull base 11. The inclined pull block 12 slides and engages with the T-shaped pull block. The engagement between the T-shaped pull block and the inclined pull block 12 prevents the inclined pull block 12 from falling off. The lower mold 3 has an inclined pull groove for the inclined pull block 12 to slide. When the ejector plate 4 ejects the lower mold 3, the inclined pull block 12 moves inclined along the path of the T-shaped pull block and disengages from the undercut.

[0029] The side end of the inclined base 11 is also provided with an inclined ejector assembly 3 13. The inclined ejector assembly 3 13 is used to form the undercut 3. The inclined ejector assembly 3 13 includes a follower block 14 and a hinge 15. The tail of the follower block 14 is hinged to the hinge 15. The hinge 15 is provided on the ejector plate 4. The inclined base 11 is provided with a limiting inclined surface 16 for abutting the follower block 14. By setting the limiting inclined surface 16, the follower block 14 can be reset when the mold is closed.

[0030] The inclined top assembly 2 10 includes an inclined pull block 2 17 and an inclined pull rod 18. The inclined pull rod 18 is located at the bottom of the inclined pull block 2 17, and a hinge 15 is also provided at the tail of the inclined pull rod 18. The inclined pull block 2 17 is used to form the inverted buckle 2. The hinge 15 includes a base 19, a sliding block 20 and a hinge block 21. A sliding groove 22 is provided in the base 19. The sliding block 20 is slidably located in the sliding groove 22. The hinge block 21 is hinged on the sliding block 20. Through the cooperation between the sliding block 20 and the sliding groove 22, and by hinged on the sliding block 20, the follower block 14 and the inclined pull block 2 17 are tilted out to complete the core pulling.

[0031] A guide block 23 is also fixedly installed on the fixed plate 6. The follower block 14 and the inclined pull rod 18 are slidably engaged with the guide block 23. An inclined hole 24 for guiding direction is opened in the guide block 23. The moving direction of the follower block 14 and the inclined pull rod 18 is controlled by the inclined hole 24. There is no need to open a guide square hole in the lower mold 3 and the fixed plate 6, thereby reducing production costs. A guide protrusion 25 is also provided on the lower mold 3. A guide groove 26 is opened in the upper mold 2. The guide protrusion 25 is adapted to the guide groove 26, thereby increasing the mold closing accuracy.

[0032] Ejector plate 4 includes ejector plate 4-1 and ejector plate 4-2. Ejector rod 8 is set on ejector plate 4-2, and hinge 15 is set on ejector plate 4-1. After mold opening, ejector plate 4 drives lower mold 3 to be ejected outward. At this time, ejector plate 4-1 and ejector plate 4-2 move together, so that inclined pull block 12 completes core pulling and undercut 1 is disengaged. Then ejector plate 4-2 stops moving, and ejector plate 4-1 continues to move, so that inclined ejector assembly 2 10 and inclined ejector assembly 3 13 complete inclined ejection, so that inclined pull block 2 17 and follower block 14 disengage from undercut and support body 90 disengages from mold.

[0033] Of course, the above are just typical examples of this utility model. In addition, this utility model may have many other specific implementation methods. All technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of protection claimed by this utility model.
