Description

Technical Field

[0001] The utility model relates to the technical field of civil air defense doors, in particular to a mold for producing civil air defense doors. Background Art

[0002] Civil defense doors are the doors at the entrances and exits of people's defense projects. There are distinct classifications of civil defense doors, including ordinary single-leaf and double-leaf protective closed doors and closed doors, movable threshold single-leaf and double-leaf protective closed doors and closed doors, and other civil defense equipment. Civil defense is also known as civil defense. Civil defense is an internationally accepted term. It is an activity in which the government mobilizes and organizes the masses to take anti-air raid, disaster resistance and relief measures, implement rescue operations, and prevent and reduce the hazards of disasters. Civil defense doors belong to civil defense protection equipment.

[0003] In the production of civil defense doors, the use of molds is a common method. First, the corresponding mold needs to be designed according to the design requirements and size specifications of the civil defense doors. The mold is usually made of metal or plastic and has the shape and size required for the civil defense door. The prepared raw materials are placed in the mold, and then pressure is applied to make it adapt to the shape of the mold. The specific molding process depends on the process used, which can be injection molding, die casting or stamping. In this process, the mold will apply pressure and shape to the raw materials to form them into the required shape of the civil defense door.

[0033] 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.

[0034] Reference Figure 2 - Figure 4 , an embodiment of the utility model is provided: a mold for producing a civil air defense door, comprising a base 1, a plurality of splicing blocks 3 are arranged on the top of the base 1, a plurality of mounting columns 4 are fixedly connected to the top of the base 1, a plurality of slots 6 are provided at the bottom of the splicing blocks 3, the outer wall of the mounting column 4 is arranged inside the slot 6, a plurality of wedge-shaped slide bars 11 are slidably connected inside the base 1, a threaded column 12 is rotatably connected to one end of the wedge-shaped slide bar 11, a handle 13 is fixedly connected to one end of the threaded column 12, the outer wall of the threaded column 12 is slidably connected to the inside of the base 1, a plurality of wedge-shaped slide bars 8 are slidably connected inside the base 1, the bottom of the wedge-shaped slide bar 8 is fitted with the top of the wedge-shaped slide bar 11, a limiting groove 10 is provided inside the wedge-shaped slide bar 8, both sides of the mounting column 4 are rotatably connected with a clamping plate 9, a spring 7 is provided inside the mounting column 4, one end of the spring 7 is fixedly connected to the inner wall of the mounting column 4, the other end of the spring 7 is fixedly connected to the top of the wedge-shaped slide bar 8, and the base 1 is slidably connected with a bottom plate 2;

[0035] Specifically, if the thickness of the mold needs to be adjusted, it can be achieved according to the splicing of the splicing block 3. The splicing block 3 will be connected to the slot 6 through the mounting column 4. After the mounting column 4 is inserted into the slot 6, the handle 13 can drive the threaded column 12 to rotate. Due to the characteristics of the threaded column 12, it will move inside the object threadedly connected to it when rotating. The rotation of the threaded column 12 will push the wedge-shaped slide bar 11 to move, and the wedge-shaped slide bar 11 will then push the wedge-shaped slide bar 18 up. In this way, the limit position inside the wedge-shaped slide bar 18 The groove 10 can push one side of the splint 9 to rotate the splint 9, so that the other side of the splint 9 is pressed against the inner wall of the slot 6, prompting the splicing block 3 to complete the splicing. When it is removed, the handle 13 can be rotated in the opposite direction to make the wedge-shaped slide bar 2 11 slide outward, then the wedge-shaped slide bar 1 8 will slide downward under the action of the spring 7, and then the limit groove 10 will drive the splint 9 to rotate in the opposite direction to open it. This design of using the splicing block 3 to adjust the mold thickness is easy and efficient to operate, and can accurately meet different production needs.

[0036] Reference Figure 3 - Figure 5A sealing assembly is provided between the splicing block 3 and the base 1, and the sealing assembly includes a sealing gasket 1 5, the outer wall of the sealing gasket 1 5 is in contact with the outer wall of the base 1, the outer wall of the sealing gasket 1 5 is in contact with the outer wall of the splicing block 3, a sealing gasket 2 14 is fixedly connected inside the base 1, the outer wall of the sealing gasket 2 14 is in contact with the outer wall of the bottom plate 2, a placement plate 15 is fixedly connected inside the base 1, and the outer wall of the bottom plate 2 is in contact with the top of the placement plate 15;

[0037] Specifically, when the splicing blocks 3 are spliced, a sealing gasket 5 is arranged between them to enhance the sealing performance, which can effectively prevent the raw liquid from flowing out during injection molding. At the same time, a sealing gasket 2 14 is arranged on the inner wall of the base 1. During injection molding, the bottom plate 2 is located on the top of the placement plate 15, and the sealing gasket 2 14 seals the base 1 and the base 1, thereby preventing the raw liquid from flowing into the inside of the base 1. At the same time, the placement plate 15 supports the bottom plate 2, which is convenient for effectively relieving the pressure of the bottom mechanism and increasing its service life.

[0038] Reference Figure 1 , Figure 4 and Figure 5 The bottom wall of the base 1 is rotatably connected to a left-right symmetrical special-shaped rotating block 21, the bottom of the base plate 2 is fixedly connected to a left-right symmetrical fixed plate 17, the bottom wall of the base 1 is rotatably connected to an electric push rod 16, the output end of the electric push rod 16 is fixedly connected to a coupling 20, the outer wall of the coupling 20 is rotatably connected between the left-right symmetrical special-shaped rotating blocks 21, a slide groove 18 is opened inside the fixed plate 17, a round block 19 is fixedly connected to one side of the outer wall of the special-shaped rotating block 21, and the outer wall of the round block 19 is slidably connected inside the slide groove 18;

[0039] Specifically, during the demoulding operation, the electric push rod 16 can drive the special-shaped rotating block 21 to rotate through the coupling 20. The coupling 20 can ensure that the electric push rod 16 adapts to the rotation generated at the connection when it moves. At this time, the round block 19 on one side of the special-shaped rotating block 21 can lift the fixed plate 17, and the fixed plate 17 drives the bottom plate 2 to rise. The fixed plate 17 is provided with a slide groove 18 inside, so that the round block 19 can slide inside it. In the process of the round block 19 lifting the fixed plate 17, the position change of the round block 19 can be adapted. In this way, the civil air defense door can be ejected from the mold through the bottom plate 2. This design makes the demoulding process automatic and efficient. The synergistic effect of the electric push rod 16 and the coupling 20 enables the special-shaped rotating block 21 to rotate accurately, thereby stably lifting the fixed plate 17. The connection between the fixed plate 17 and the bottom plate 2 ensures that the bottom plate 2 can evenly apply force when it is lifted, so that the civil air defense door can be smoothly ejected from the mold. This demoulding method not only improves production efficiency.

[0040] Working principle: When the mold thickness needs to be adjusted, it can be achieved by splicing the splicing blocks 3. The splicing blocks 3 will be connected to the slots 6 through the mounting columns 4. After the mounting columns 4 are inserted into the slots 6, the threaded columns 12 can be driven to rotate by the handles 13. The rotation of the threaded columns 12 can push the wedge-shaped slide bar 2 11, and the wedge-shaped slide bar 1 8 can be pushed up by the wedge-shaped slide bar 2 11, so that one side of the clamping plate 9 can be pushed by the limiting groove 10 inside the wedge-shaped slide bar 1 8, so that the clamping plate 9 can be rotated, so that the other side of the clamping plate 9 is pressed against the inner wall of the slot 6. , so that the splicing block 3 is completed. When it is removed, the handle 13 can be rotated in the opposite direction to make the wedge-shaped slide bar 11 slide outward, and the wedge-shaped slide bar 18 will slide downward again under the action of the spring 7, so that the clamping plate 9 is driven by the limit groove 10 to rotate in the opposite direction to open it. When demolding, the electric push rod 16 can drive the special-shaped rotating block 21 to rotate through the coupling 20, and the round block 19 on one side of the special-shaped rotating block 21 can lift the fixed plate 17, and the fixed plate 17 drives the bottom plate 2 to rise, so that the civil defense door is pushed out of the mold through the bottom plate 2.

[0041] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
