However, during the molding process, it is found that the injection molding equipment is equipped with a certain heat dissipation structure to assist the rapid shaping of the model. Usually, the heat dissipation structure is to effectively dissipate heat for the outside of the model. If the inside of the model is not subjected to heat dissipation treatment after high-temperature die-casting, wrinkles and other phenomena will appear on the inner wall of the wet wipes cover, resulting in a decrease in the overall yield rate.

[0014] Preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of the present invention and are used to explain the principles of the present invention together with the embodiments of the present invention.
[0015] See also Figure 1-Figure 5 The present invention provides a rapid injection molding device for wet wipes cover, comprising a mold table 1, a groove body 3 is provided in the middle of the mold table 1, a lifting component is movably connected in the groove body 3, a water tank 2 is provided in the middle of the mold table 1, the water tank 2 is arranged on the outside of the groove body 3, and the water flowing in the water tank 2 is in contact with the outer wall of the groove body 3; an electric push rod 6 is fixedly installed on the back of the mold table 1, a connecting rod 5 is connected to the top of the electric push rod 6, one end of the connecting rod 5 is bent and fixedly connected to a top plate 7, an upper mold table 8 is movably installed on the bottom of the top plate 7, an outer frame 9 is fixedly installed on the top wall of the upper mold table 8, a heat dissipation component 11 is arranged in the middle of the upper mold table 8, and the upper mold table 8 corresponds to the groove body 3.
[0016] A plurality of through holes 13 are provided on the edge of the outer frame 9, and the plurality of through holes 13 are used for the air outlet of the heat dissipation component 11. A group of card slots 12 are provided in the middle of the upper mold platform 8, and two groups of holes are provided inside the card slots 12. Magnetic suction plates are fixedly installed at the top ends of the two groups of holes.
[0017] The heat dissipation component 11 includes a bracket 14, which has a cross structure and a lateral end of the bracket 14 that is longer than a longitudinal end. A number of dual-axis motors 16 are symmetrically installed in the middle of the bracket 14, and the output ends of the dual-axis motors 16 are fixedly connected to fans 15. The dual-axis motors 16 are connected through a group of controllers, which are not shown in the figure. At the same time, the dual-axis motors 16 do not need to be started synchronously. After starting, the dual-axis motors 16 drive the fans 15 to rotate, thereby generating wind to blow toward the outside of the outer frame 9. Therefore, at this time, the inner side of the model adsorbed by the upper mold table 8 can be air-cooled, thereby improving the cooling effect of the model, avoiding the deformation of the inner side of the model due to high temperature, and improving the yield rate.
[0018] A water tank 4 is fixedly connected to one side of the end of the mold table 1, and circulation pipes 17 are fixedly installed at both ends of the water tank 4. The ends of the two circulation pipes 17 are embedded in the mold table 1 and inserted into the water tank 2. A micro water pump is preset in the middle of the circulation pipe 17. By setting the micro water pump, the water in the water tank 4 is transported to the inside of the water tank 2. Since the two ends of the water tank 2 are connected to the two circulation pipes 17, the water can circulate in the circulation pipe 17, thereby avoiding the water being in a static state for a long time and forming warmth under a high temperature state, thereby improving the overall water cooling effect.
[0019] Cylinders 10 are fixedly connected to both sides of the top of the top plate 7. The output ends of the two cylinders 10 pass through the top plate 7 and extend to the top wall of the upper mold platform 8. Push rods are fixedly installed at the output ends of the cylinders 10. The bottom ends of the push rods are fixedly connected to the upper mold platform 8. A plurality of adsorption sheets are evenly installed on the bottom wall of the upper mold platform 8. The upper mold platform 8 is driven to move by the cylinders 10, so that the upper mold platform 8 can be further entered into the inner side of the trough body 3, which is convenient for squeezing and lifting the model.
[0020] The lifting component includes a lifting platform 18 that is tightly fitted on the trough body 3. A protrusion is arranged in the middle of the lifting platform 18, and magnetic attraction plates 19 are evenly installed on both sides of the top of the protrusion.
[0021] The position of the protrusion corresponds to the position of the slot 12, and the protrusion can be embedded in the middle of the slot 12. The two magnetic plates 19 on the protrusion are embedded in the inside of the through hole 13 and are magnetically connected to the magnetic sheet. The lifting platform 18 can move up and down with the movement of the upper mold platform 8. As the upper mold platform 8 moves downward, the slot 12 covers the protrusion, and the through hole 13 in the middle (including the magnetic sheet inside) and the magnetic plate 19 are interlaced and magnetically connected. Later, when the upper mold platform 8 rises, the lifting platform 18 moves synchronously. At this time, the model between the upper mold platform 8 and the lifting platform 18 is pulled up, thereby improving the overall extraction efficiency.
[0022] During the working process, the high-temperature plastic is first injected into the interior of the tank body 3, and the electric push rod 6 and the cylinder 10 are started to drive the upper mold platform 8 to move downward (i.e., embedded into the interior of the tank body 3), and then extrusion molding is performed. The extrusion molding time needs to be controlled within 30-45 seconds. At this time, the slot 12 and the through hole 13 in the middle of the upper mold platform 8 can be docked with the protrusion and the magnetic plate 19 in the middle of the lifting platform 18, which can not only realize the extrusion process, but also when the upper mold platform 8 rises later, the entire wet wipes cover model is pulled up, which is convenient for later collection; The water tank 2 is located on the outside of the tank body 3 and the two are in contact with each other. There is flowing water in the water tank 2, which is convenient for cooling the outside of the wet wipes cover. When the inside of the model needs to be cooled, the inside of the model is in contact with the upper mold platform 8 and the outer frame 9. By starting several groups of dual-axis motors 16, the fans 15 connected thereto are driven to move and generate wind force, so as to cool the inside, ensure that both the inside and outside of the model can be cooled quickly, and improve the integrity of the model.
