Technical Field

[0001] The utility model relates to a mould, in particular to a foam box forming mould. Background Art

[0002] A foam box refers to a box-type packaging container made of foam plastic. It has the characteristics of light weight, heat insulation, sound absorption, shock resistance and corrosion resistance. The foam box is easy to shape and light in weight. It is also a good electrical insulating material. To make a foam box, the mixed raw materials need to be placed in a mold and heated by a heating equipment to make the raw materials foam and expand, filling the entire mold. After the foam cools and takes shape, the product is taken out of the mold.

[0003] The existing foam box forming mold is provided with a push rod mechanism for demoulding, and the push rod mechanism is usually slidably connected to the foam box forming mold. After the foam box forming mold is used for a long time, a gap will appear between the push rod mechanism and the foam box forming mold, thereby affecting the forming quality of the foam box. Utility Model Content

[0004] In order to overcome the disadvantage of the existing foam box forming mold that after long-term use, a gap will appear between the push rod mechanism inside the foam box forming mold and the foam box forming mold, thereby affecting the molding quality of the foam box, the technical problem to be solved by the utility model is to provide a foam box forming mold that can ensure the molding quality of the foam box.

[0005] In order to solve the above technical problems, the utility model provides a foam box forming mold, comprising a support frame, a base, a lower mold body, an upper mold body, a cylinder, a slider, a shell, a material storage frame, a heating type pumping machine, a guide column and a bottom plate. The base is installed at the lower part of the support frame, and the lower mold body is installed on the top of the base. The lower part of the lower mold body is slidably connected to a left and a right shell, and the bottom of the shell is connected with a guide column. The guide column and the base are slidably connected, and a bottom plate is installed between the two guide columns. The left and right sides of the lower mold body are both equipped with material storage frames, and the left and right sides of the lower mold body are both equipped with a heating type pumping machine. The heating pumping machine is connected to the material storage frame through a pipeline. The top of the support frame is slidably connected with a slider, and the bottom of the slider is equipped with a cylinder. The upper mold body is connected to the telescopic rod of the cylinder. When the upper mold body and the lower mold body cooperate, a gap consistent with the shape of the foam box will be generated. It is characterized in that it also includes an air bag, a hose and an air pump. The air bag is installed in the shell, and the air pump is installed on the top of the bottom plate. The air pump is connected to the air bag through the hose.

[0006] Preferably, a handle is also included, and the front side of the base plate is connected to the handle.

[0007] Preferably, it also includes support blocks, and a plurality of support blocks are connected to both left and right sides of the bottom plate, and the support blocks are in contact with the base.

[0008] Preferably, a heating block is provided on the upper mold body.

[0009] Preferably, the gap width between the upper mold body and the lower mold body when they are matched is consistent with the thickness of the foam box.

[0010] Preferably, the material storage frame is made of stainless steel.

[0011] The beneficial effect of the utility model is that by adding an air bag, a hose and an air pump, the air pump is controlled to deliver air to the air bag, so that the air bag expands and the lower mold body is sealed, avoiding the gap on the lower mold body affecting the quality of foam box molding, and improving the processing efficiency of the foam box.

DETAILED DESCRIPTION

[0016] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0017] Example 1

[0018] A foam box forming mold, such as Figure 1-Figure 3As shown, it includes a support frame 1, a base 2, a lower mold body 3, an upper mold body 4, a cylinder 5, a slider 6, a shell 7, a handle 12, a storage frame 13, a heated extractor 14, a guide column 15 and a bottom plate 16. The base 2 is installed at the lower part of the support frame 1, and the lower mold body 3 is installed on the top of the base 2. The lower part of the lower mold body 3 is slidably connected to a left and a right shell 7, and the bottom of the shell 7 is connected to the guide column 15. The guide column 15 is slidably connected to the base 2, and a bottom plate 16 is installed between the two guide columns 15. The handle 12 is connected to the front side of the bottom plate 16. The left and right sides of the lower mold body 3 are installed with storage frames 13, and the storage frame 13 is made of stainless steel. The stainless steel material has The characteristic of not easy to rust can extend the service life of the material storage frame 13. The left and right sides of the lower mold body 3 are installed with a heating pump 14, and the heating pump 14 is connected to the material storage frame 13 through a pipeline. The top of the support frame 1 is slidably connected with a slider 6, and the bottom of the slider 6 is installed with a cylinder 5. The telescopic rod of the cylinder 5 is connected to the upper mold body 4, and the upper mold body 4 is provided with a heating block. When the upper mold body 4 and the lower mold body 3 are matched, a gap consistent with the shape of the foam box will be generated. It is characterized in that it also includes an airbag 8, a hose 9 and an air pump 10. The airbag 8 is installed in the shell 7, and the air pump 10 is installed on the top of the bottom plate 16. The air pump 10 is connected to the airbag 8 through the hose 9.

[0019] The telescopic rod of the control cylinder 5 is extended to drive the upper mold body 4 to move downward into the lower mold body 3, and the vacuum pump 10 is controlled to deliver air to the airbag 8, so that the airbag 8 expands and the lower mold body 3 is sealed. Then the heating pump 14 is controlled to start and the material in the storage frame 13 is pumped into the gap between the upper mold body 4 and the lower mold body 3 after heating. At the same time, the heating block on the upper mold body 4 is controlled to work so that the material is heated more evenly. When the material is completely formed and cooled, the telescopic rod of the control cylinder 5 is retracted to drive the upper mold body 4 to move upward. Then the slider 6 is controlled to slide to the right to drive the cylinder 5 and the upper mold body 4 to move to the right. Then the handle 12 is held to drive the bottom plate 16 to move upward, so that the guide column 15 drives the shell 7 to move upward so that the processed foam box is separated from the lower mold body 3 upward, thus completing the foam box molding and demolding work.

[0020] Example 2
