[0009] The advantages and beneficial effects of this utility model are as follows: This utility model provides a mold for producing cosmetic box bodies. When the punch enters the cavity, the punch squeezes the push plate, causing the push plate to fit tightly against the bottom of the cavity. The spring is compressed under force. After injection molding is completed, the upper and lower molds separate. Under the action of the spring force, the movable plate pushes the push rod and the push plate, thereby allowing the molded packaging box to be automatically removed from the cavity. Coolant can be injected into the guide channel through the liquid inlet, which can effectively accelerate the cooling speed of the packaging box after injection molding. This mold has a simple structure, is easy to operate, and has a good cooling effect. It can automatically eject the injection-molded packaging box, reducing the workload of workers while effectively improving the processing efficiency of packaging boxes. Attached Figure Description

[0015] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0016] like Figure 1-3As shown, this utility model is a cosmetic box production mold, including a lower mold base 1. Four support rods 2 arranged in a matrix are provided above the lower mold base 1. An upper mold base 3 is sleeved on the upper end of the four support rods 2, and the support rods 2 and the upper mold base 3 are movably connected, allowing the upper mold base 3 to reciprocate vertically on the support rods 2. An upper mold 4 is provided in the lower center of the upper mold base 3, and a punch 5 is provided below the upper mold 4. Two symmetrical support seats 7 are provided in the upper center of the lower mold base 1, and the upper parts of the two support seats 7 are fixedly connected to a lower mold 8. A cavity 9 matching the punch 5 is provided at the upper end of the lower mold 8. When the upper mold base 3 moves, the punch 5 moves accordingly through the transmission of the upper mold 4. Through the mutual cooperation between the punch 5 and the cavity 9, the injection mold cavity of the cosmetic box can be formed. The lower mold base 1 is located between the two support seats 7. A base plate 10 has four springs 14 arranged in a matrix on its upper part. The upper part of each spring 14 is fixedly connected to a movable plate 13. Push rods 11 are provided on both sides of the upper part of the movable plate 13. A push plate 12 is provided at the bottom of the cavity mold 9. The upper part of each push rod 11 passes through the lower mold 8 and is fixedly connected to the push plate 12. The push rod 11 is movably connected to the lower mold 8. When the punch 5 enters the cavity mold 9, the punch 5 squeezes the push plate 12, so that the push plate 12 is tightly attached to the bottom of the cavity mold 9. At this time, under the pressure of the push rods 11 and the movable plate 13, the springs 14 are compressed. After the injection molding is completed, the upper mold 4 and the lower mold 8 separate from each other. Under the action of the elastic force of the springs 14, the movable plate 13 pushes the push rods 11 and the push plate 12, so that the molded packaging box can be automatically taken out from the cavity mold 9 under the push of the push plate 12.

[0017] The upper mold base 3 is provided with an injection port 6 at the middle of its upper end. The injection port 6 extends to the lower end of the punch 5, and injection can be performed into the cavity mold 9 through the injection port 6.

[0018] The lower mold 8 has liquid inlets 15 at both ends on one side and liquid outlets 16 at both ends on the side away from the liquid inlets 15. The liquid inlets 15 and liquid outlets 16 are connected by a flow channel 17. Coolant can be injected into the flow channel 17 through the liquid inlets 15. The coolant can effectively accelerate the cooling speed of the packaging box after injection molding. At the same time, the used coolant can be discharged through the liquid outlets 16.

[0019] The upper mold 4 is provided with positioning rods 18 at each of its four lower corners, and the lower mold 8 is provided with positioning holes 19 that match the positioning rods 18. The positioning rods 18 can be inserted into the positioning holes 19. Through the cooperation between the positioning rods 18 and the positioning holes 19, the positioning accuracy between the upper mold 4 and the lower mold 8 is effectively improved.

[0020] The lower end of the positioning rod 18 is designed with an arc surface, which makes it easier for the positioning rod 18 to be inserted into the positioning hole 19.

[0021] Specifically, in this utility model, when the upper mold base 3 moves, the upper mold 4 drives the punch 5 to move as well. Through the cooperation between the punch 5 and the die 9, the injection mold cavity of the cosmetic box can be formed. Injection can be performed into the die 9 through the injection port 6. When the punch 5 enters the die 9, the punch 5 squeezes the push plate 12, so that the push plate 12 is tightly attached to the bottom of the die 9. At this time, under the pressure of the push rod 11 and the movable plate 13, the spring 14 is compressed. After the injection is completed, the upper mold 4 and the lower mold 8 separate from each other. Under the action of the spring 14, the movable plate 13 pushes the push rod 11 and the push plate 12. Thus, under the push of the push plate 12, the molded packaging box can be automatically taken out from the inside of the die 9. Coolant can be injected into the guide channel 17 through the liquid inlet 15. The coolant can effectively accelerate the cooling speed of the packaging box after injection.

[0022] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
