DETAILED DESCRIPTION

[0029] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0030] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0031] Example 1, as Figures 1-4 As shown, this utility model provides a mold for producing fully degradable plastic lunch boxes, including: a base plate 1, a stepper motor 101 fixedly installed at the center of the top outer surface of the base plate 1, and a connecting rod 102 fixedly installed at the output end of the stepper motor 101; two lower molds 111, both fixedly installed on both sides of the connecting rod 102, with rectangular slots 112 on the top of the two lower molds 111 and through holes 118 at the center of the bottom of each of the two lower molds 111; an annular groove 104, located at the center of the top outer surface of the base plate 1; and two arc-shaped plates 103, both fixedly installed at the bottom of the connecting rod 102. Two connecting rods 102 are symmetrical about the stepper motor 101. The other ends of the two arc plates 103 are movably embedded in the annular groove 104. An L-shaped plate 105 is fixedly installed at the center of one side of the base plate 1. A cylinder 106 is fixedly installed at the top of the L-shaped plate 105. The output end of the cylinder 106 passes through the L-shaped plate 105. A sealing cover 107 is fixedly installed at the output end of the cylinder 106. An upper mold 116 is fixedly installed at the center of the bottom of the sealing cover 107. A rectangular clamping plate 115 is fixedly installed at the bottom edge of the sealing cover 107. A feed pipe 114 is fixedly installed on one side of the top of the sealing cover 107.

[0032] In this embodiment, the stepper motor 101 is turned on to drive the connecting rod 102 to rotate. The connecting rod 102 drives one of the lower molds 111 to move above the positioning plate 108. The positioning plate 108 can improve the stability of the lower mold 111. Then, the cylinder 106 is turned on to drive the sealing cover 107 to move down, so that the upper mold 116 at the bottom of the sealing cover 107 is embedded in the interior of the lower mold 111. The rectangular card plate 115 at the bottom edge of the sealing cover 107 is embedded in the interior of the rectangular card slot 112, which better improves the sealing performance and prevents the plastic melt from flowing out. The plastic melt is injected between the lower mold 111 and the upper mold 116 through the feed pipe 114, so that it cools and forms a plastic lunch box.

[0033] Example 2, as Figures 1-4As shown, two movable plates 113 are movably embedded inside the lower mold 111. Reset springs 117 are fixedly installed at the four corners of the bottom of the two movable plates 113. The other ends of the multiple reset springs 117 are fixedly installed at the bottom of the lower mold 111. A positioning plate 108 is fixedly installed on the outer surface of the bottom plate 1 near the L-shaped plate 105. A U-shaped plate 109 is fixedly installed at the center of the side of the bottom plate 1 away from the L-shaped plate 105. An electric push rod 110 is fixedly installed inside the U-shaped plate 109.

[0034] In this embodiment, after cooling is complete, cylinder 106 moves sealing cover 107 and upper mold 116 upwards. Then, stepper motor 101 is activated to move lower mold 111 onto U-shaped plate 109. Another lower mold 111 moves onto positioning plate 108 for injection molding. An electric push rod 110 is fixedly installed inside U-shaped plate 109. The electric push rod 110 is activated so that its output end passes through through hole 118. Then, moving plate 113 is lifted out from inside lower mold 111, so that moving plate 113 pushes the lower mold 111... The plastic lunch box can be removed without manual handling by workers, which improves safety. After the plastic lunch box is removed, the electric push rod 110 retracts, and the moving plate 113 retracts into the lower mold 111 under the elastic force of multiple return springs 117. Two arc-shaped plates 103 are fixedly installed at the bottom of the connecting rod 102. Both arc-shaped plates 103 are movably embedded in the annular groove 104, which can improve the stability of the connecting rod 102. The arc-shaped plates 103 rotate inside the annular groove 104 as the connecting rod 102 rotates.

[0035] Working principle: In use, the stepper motor 101 is turned on to drive the connecting rod 102 to rotate. The connecting rod 102 moves one of the lower molds 111 above the positioning plate 108. The positioning plate 108 improves the stability of the lower mold 111. Then, the cylinder 106 is turned on to move the sealing cover 107 downward, so that the upper mold 116 at the bottom of the sealing cover 107 is embedded in the lower mold 111. The rectangular retaining plate 115 at the bottom edge of the sealing cover 107 is embedded in the rectangular retaining groove 112 to further improve the sealing performance and prevent the plastic melt from flowing out. The plastic melt is injected between the lower mold 111 and the upper mold 116 through the feed pipe 114 to cool and form a plastic lunch box. After cooling, the cylinder 106 moves the sealing cover 107 and the upper mold 116 upward. Then, the stepper motor 101 is turned on to move the lower mold 111 onto the U-shaped plate 109. Another lower mold 111 moves to the positioning plate 108 for injection molding. An electric push rod 110 is fixedly installed inside the U-shaped plate 109. When the electric push rod 110 is turned on, the output end passes through the through hole 118, and then the moving plate 113 is lifted out from inside the lower mold 111, so that the moving plate 113 can take out the plastic lunch box inside the lower mold 111 without the need for manual handling by workers, which improves safety. After the plastic lunch box is taken out, the electric push rod 110 retracts, and the moving plate 113 retracts into the lower mold 111 under the elastic force of multiple return springs 117. Two arc-shaped plates 103 are fixedly installed at the bottom of the connecting rod 102. Both arc-shaped plates 103 are movably embedded in the annular groove 104, which can improve the stability of the connecting rod 102. The arc-shaped plates 103 rotate inside the annular groove 104 as the connecting rod 102 rotates.

[0036] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
