Technical Field

[0001] The utility model relates to the technical field of perspective window production molds, in particular to a crack-proof production mold for a perspective window of a drum washing machine. Background Art

[0002] The perspective window of a drum washing machine is usually called a "viewing window" or "washing tub viewing window". It is a transparent window on the drum washing machine through which you can see the washing situation inside the washing machine.

[0003] The function of this perspective window is to facilitate the user to observe the washing status of the clothes during the washing process and to ensure that the washing process is proceeding normally. The perspective window of some drum washing machines may also have special functions, such as leak-proof design or sound insulation effect.

[0004] However, the existing compression molding device for the perspective window of the drum washing machine has low heating and cooling efficiency. In addition, the mold cooling is not uniform, which is prone to local adhesion. During the ejection process of the finished product, it is easy to cause uneven force and cracking, affecting product quality. Utility Model Content

[0011] A further improvement of the technical solution of the utility model is that the bottom end of the upper mold is movably connected to the inner wall of the lower mold.

[0012] A further improvement of the technical solution of the utility model is that: the bottoms of the four corners of the upper mold are fixedly connected with positioning columns, and the upper surface of the base is provided with positioning grooves for docking the positioning columns.

[0013] A further improvement of the technical solution of the utility model is that the inner wall of the positioning groove is plugged into the outer wall of the bottom end of the positioning column.

[0014] A further improvement of the technical solution of the utility model is that the upper surface of the upper mold is fixedly connected to the bottom end of the downward pressing hydraulic rod.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0026] The present invention is further described in detail below in conjunction with the embodiments:

[0027] Example 1

[0028] like Figure 1-5 As shown, the utility model provides a crack-proof drum washing machine perspective window production mold, including a base 1, an upper mold 2, a downward pressure hydraulic rod 3 and a lower mold 8, the outer wall of the lower mold 8 is staggered with electric heating wires 9 for heating it and a cooling surround tube 10 for cooling it, the electric heating wires 9 are externally connected to a heating control system, and the cooling surround tube 10 is externally connected to a cooling control system.

[0029] The plastic particles are placed in the lower mold 8. Then, the heating control system is started to heat the lower mold 8 to a certain temperature, so that the plastic particles soften and begin to flow. Then the downward hydraulic rod 3 is started, so that the downward hydraulic rod 3 pushes the upper mold 2 downward to close the mold with the lower mold 8. The softened plastic particles are pressed into the mold to form the desired shape.

[0030] The first and second fans 6 and 7 for dissipating heat for the lower mold 8 are fixedly connected to the two sides of the base 1, respectively. An ejection groove 13 is provided at the bottom of the inner wall of the lower mold 8, and an ejection rod 14 for ejection is movably connected to the inner wall of the ejection groove 13.

[0031] The bottom end of the ejector rod 14 is fixedly connected with the upper moving plate 11, and the bottom surface of the upper moving plate 11 is fixedly connected with the ejector hydraulic rod 12 for pushing it upward. The bottom end of the ejector hydraulic rod 12 is fixedly connected to the bottom of the inner wall of the base 1, and the cooling system is started to transport the coolant to the cooling surround pipe 10 to cool the inside of the lower mold 8 to solidify the plastic particles. At the same time, the first fan 6 and the second fan 7 are started synchronously to assist in cooling and forming the final product. Finally, the downward pressure hydraulic rod 3 is started to drive the upper mold 2 to move upward, and then the ejector hydraulic rod 12 is started to push the ejector rod 14 on the upper surface of the upper moving plate 11 to eject the product. Finally, the product is taken out to complete. 14 is divided into multiple groups, so that when the finished product is ejected, the product can be evenly stressed, thereby preventing the perspective window of the drum washing machine from breaking and ensuring product quality.

[0032] The bottom end of the upper mold 2 is movably connected to the inner wall of the lower mold 8 .

[0033] Example 2

[0034] like Figure 1-5 As shown, based on Example 1, the utility model provides a technical solution: preferably, the bottom of the four corners of the upper mold 2 are fixedly connected with positioning columns 4, and the upper surface of the base 1 is provided with positioning grooves 5 for docking the positioning columns 4.

[0035] The inner wall of the positioning groove 5 is plugged into the outer wall of the bottom end of the positioning column 4 , and the upper surface of the upper mold 2 is fixedly connected to the bottom end of the downward pressing hydraulic rod 3 .

[0036] The top end of the downward hydraulic rod 3 is fixedly connected to one side of the base 1 through a mounting frame.

[0037] The following is a detailed description of the working principle of the production mold of the anti-breakage drum washing machine perspective window.

[0038] like Figure 1-5 As shown, when in use, the electric heating wire 9 is connected to an external heating control system, and the cooling surround tube 10 is connected to an external cooling control system.

[0039] First, put the plastic particles into the lower mold 8. Then, start the heating control system to heat the lower mold 8 to a certain temperature, so that the plastic particles soften and start to flow. Then start the downward hydraulic rod 3, so that the downward hydraulic rod 3 pushes the upper mold 2 downward to close the mold with the lower mold 8. The softened plastic particles are pressed into the mold to form the desired shape.

[0040] Afterwards, the cooling system is started to transport the coolant to the cooling surround pipe 10 to cool the inside of the lower mold 8 to solidify the plastic particles. At the same time, the first fan 6 and the second fan 7 are started synchronously to assist in cooling and forming the final product. Finally, the downward hydraulic rod 3 is started to drive the upper mold 2 to move upward, and then the ejection hydraulic rod 12 is started to push the ejector rod 14 on the upper surface of the upper plate 11 to eject the product, and finally the product is taken out to complete.

[0041] When the upper mold 2 moves down to close the mold with the lower mold 8, the bottom end of the positioning column 4 is docked with the positioning groove 5 to maintain the accuracy of the docking between the upper mold 2 and the lower mold 8, thereby ensuring the quality of the finished product.

[0042] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply that there is any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants are intended to cover non-exclusive inclusion, so that the process, method, article or equipment including a series of elements includes not only those elements, but also other elements not explicitly listed, or still includes elements inherent to such process, method, article or equipment. In the absence of more restrictions, the elements defined by the sentence "including one..." do not exclude the existence of other identical elements in the process, method, article or equipment including the elements. The above generally describes the utility model in detail, but on the basis of the utility model, some modifications or improvements can be made to it, which is obvious to the general technicians in the technical field. Therefore, modifications or improvements that do not depart from the spirit of the utility model are within the scope of protection of the utility model.
