[0001] The utility model relates to the technical field of a foam box forming die structure, in particular to a forming die for foam box production. Background Art

[0002] A foam box is a kind of storage box at present. The main body is polystyrene particles. After foaming, it is injected into a die, and the foamed polystyrene particles are coagulated and formed by the high temperature of the die, and finally produced into a foam for daily use. Because of the low price and good heat preservation performance, the foam box is widely used in different fields.

[0003] The sizes of the existing dies are fixed. Boxes with the same depth but different sizes need different dies to be produced, which increases the production cost, and it is also time-consuming and laborious to replace the dies, delaying the production efficiency. Therefore, a forming die for foam box production is proposed. Content of the Utility Model

Detailed Description of the Embodiment

[0015] The present utility model will be further described below with reference to the drawings.

[0016] Please refer to Figures 1-4 , a molding die for producing a foam box of the present utility model includes a processing table 1. Two sleeve plates 2 and a surrounding plate 3 are provided on the side wall of the top of the processing table 1. A column 8 is fixedly connected to the middle of one side edge of the top of the processing table 1. The column 8 is of an L-shaped structure. Both the sleeve plate 2 and the surrounding plate 3 are of an L-shaped structure. Movable grooves 12 are opened on both sides of the sleeve plate 2. Opposite side walls in the movable grooves 12 are rotatably connected with balls 13. The surrounding plate 3 is telescopically inserted into the movable grooves 12 through both ends;

[0017] One end of the bottom side wall of the upright column 8 is detachably connected with a first telescopic rod 7, the output end of the first telescopic rod 7 is detachably connected with a cover plate 5, the middle of the bottom side wall of the cover plate 5 is detachably connected with an inner mold 6, the middle of the bottom side wall inside the inner mold 6 is fixedly connected with an inner column 10, an outer peripheral groove 9 is arranged inside the inner mold 6 through the inner column 10, the outer peripheral groove 9 is of a loop structure, and a water inlet pipe is inserted and fixedly connected near a corner of the cover plate 5, and the water inlet pipe is communicated with the outer peripheral groove 9.

[0018] The technical effect of this solution is as follows: Start the first telescopic rod 7 to drive the inner mold 6 to descend and finally insert it into the sleeve plate 2 and the surrounding plate 3, and cover the cover plate 5 at the opening of the sleeve plate 2 and the surrounding plate 3. There is a space between the bottom end of the inner mold 6 and the processing table 1. Then, the foamed polystyrene is injected into the gap between the inner mold 6 and the sleeve plate 2 and the surrounding plate 3 through the reserved hole. When foam boxes of different sizes need to be produced, remove the screws from the processing table 1, and then push the sleeve plate 2 and the surrounding plate 3 to realize the function of moving the four corners, so as to reduce or expand the size of the sleeve plate 2 and the surrounding plate 3, and thus produce boxes of different sizes. This process does not require replacing different molds, realizes the function of producing boxes of different sizes with one mold, can directly save the cost of molds, and is also relatively convenient to adjust, and will not affect the production efficiency due to adjustment.

[0019] A fixing plate 4 is fixedly connected to the outer wall of the sleeve plate 2 near the bottom corner. The fixing plate 4 is inserted and threadedly connected with a screw. The top side wall of the processing table 1 and the positions corresponding to the fixing plate 4 are evenly provided with screw holes, and the screw passes through the fixing plate 4 and is threadedly connected in the screw holes. A second telescopic rod 14 is embedded in the middle inside the processing table 1, a top plate 11 is embedded in the middle of the top side wall of the processing table 1, the output end of the second telescopic rod 14 is detachably connected to the bottom side wall of the top plate 11, a rubber pad is embedded in the top side wall of the top plate 11, and the top plate 11 is located between the sleeve plate 2 and the surrounding plate 3.

[0020] The technical effect of this solution is as follows: To facilitate the removal of the formed box, start the second telescopic rod 14 to lift the top plate 11 upward after forming, so as to push the formed box out of the sleeve plate 2 and the surrounding plate 3, which is convenient for removing the formed box and can effectively improve the efficiency of removing the box. To improve the forming efficiency and the stability of the box after forming, inject the coolant into the outer peripheral groove 9 through the water inlet pipe to cool the formed box, so as to avoid the problem that the box is damaged and deformed due to impact after high-temperature demoulding.

[0021] Specifically, when the utility model is in use, a thrust is applied to the surrounding plate 3 and the sleeve plate 2 as needed to adjust the sizes of the sleeve plate 2 and the surrounding plate 3 to different sizes. After the adjustment is completed, the sleeve plate 2 is fixed on the processing table 1 with screws. However, to achieve the adjustment, all four corners of the sleeve plate 2 and the surrounding plate 3 must move synchronously. Therefore, after the two sleeve plates 2 are fixed, no further adjustment can be made. After the adjustment of the sleeve plate 2 and the surrounding plate 3 is completed, the first telescopic rod 7 is activated to lower the inner mold 6 and the cover plate 5. The inner mold 6 is inserted into the sleeve plate 2 and the surrounding plate 3, and at the same time, it is ensured that the cover plate 5 covers the opening at the top of the sleeve plate 2 and the surrounding plate 3. Then, foamed polystyrene is injected into the sleeve plate 2 and the surrounding plate 3. After molding, coolant is injected into the outer peripheral groove 9 to cool the molded box body, thereby accelerating the rate of temperature reduction of the box body and avoiding problems such as deformation of the box body during demolding due to high temperature. The second telescopic rod 14 is activated to push the top plate 11 upward to push the molded box body out of the sleeve plate 2 and the surrounding plate 3, facilitating the staff to remove the box body and improving the speed of material taking.

[0022] The above is only the preferred embodiment of the utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the utility model.

[0023] Other parts not detailed in the utility model belong to the prior art and will not be elaborated here.

[0024] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model and are not intended to limit them. Although the utility model has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some or all of the technical features.
