[0002] When producing multiple cutlery of the same model, especially disposable plastic cutlery, cutlery molds are usually used to produce a large number of cutlery in batches.

[0003] In the process of producing disposable cutlery, the upper mold and the lower mold are first fixedly connected, and then the material is introduced through the injection port. After the material is condensed, the upper mold is removed and the formed cutlery can be taken out. When the upper mold and the lower mold are fixedly connected, they are generally fixed and installed by multiple bolts. After the casting is completed, the bolts fixed on the upper mold and the lower mold need to be removed before demolding. It takes a long time to remove multiple bolts, and the steps are cumbersome, which makes the labor intensity of the staff high, thereby affecting the demolding efficiency of the body mold. Therefore, a cutlery mold with a fixed structure is proposed to simplify the fixing steps of the upper mold and the lower mold. Utility Model Content

The inner walls of the two rectangular grooves 22 are connected with telescopic rods 5 and springs 6. One side of the telescopic rod 5 is connected with an extension plate 4, and one side of the extension plate 4 is fixedly connected to the spring 6. There are two groups of four extension plates 4, and there are two groups of four press plates 3. One side of the four press plates 3 is connected with an L-shaped rod 31. A square groove slidably connected to the L-shaped rod 31 is arranged between two rectangular grooves 22 in each group of rectangular grooves 22. There are four L-shaped rods 31. The telescopic rods 5 and the press plates 3 connected on both sides of the four L-shaped rods 31 are respectively located inside two rectangular grooves 22 in one group of rectangular grooves 22. One side of the four L-shaped rods 31 is fixedly connected to the four extension plates 4 respectively. The lower sides of the four extension plates 4 are connected with fixed blocks 7. One side of the fixed block 7 is provided with an embedding groove 71, and the embedding groove 71 is embedded with the embedding block 13. One side of the embedding groove 71 is connected with an insertion rod 72. The outer diameter of the insertion rod 72 is the same as the inner diameter of the slot 14, and the insertion rod 72 is plugged into the slot 14.

[0028] In this embodiment, two groups of pressing plates 3 are pinched with both hands to squeeze the spring 6 and the telescopic rod 5, so that the two fixed blocks 7 in the two groups are separated from each other. After aligning the upper mold 2 with the lower mold 1, the lower mold 1 is placed on the upper side of the upper mold 2, so that the module 24 is embedded in the mold groove 11, and the insert block 13 and the insert groove 71 are aligned, so that the insertion rod 72 is aligned with the slot 14, and the pressing plate 3 is released. The spring 6 and the telescopic rod 5 are no longer under pressure, and the spring 6 and the telescopic rod 5 will rebound and move, driving the extension plate 4, the L-shaped rod 31 and the pressing plate 3 to move back, so that the insertion rod 72 is inserted into the slot 14, and the insert groove 71 wraps the outer wall of the insert block 13, and the upper mold 2 is fixedly connected to the upper side of the lower mold 1.

[0029] Example 2

[0030] like Figure 3 and Figure 4As shown, in each group of rectangular grooves 22, two rectangular grooves 22 have inner walls provided with sliding grooves 23, there are four sliding grooves 23, and the cross-sections of the four sliding grooves 23 are all T-shaped. One side of four L-shaped rods 31 is connected with a slider 32, there are four sliders 32, and the cross-sections of the four sliders 32 are all T-shaped. The four sliders 32 are slidably connected to the four sliding grooves 23 respectively.

[0031] In this embodiment, when the telescopic rod 5 and the spring 6 are extended and retracted, the pressing plate 3 and the L-shaped rod 31 are moving at the same time, and one side of the L-shaped rod 31 slides along the inner wall of the rectangular groove 22, and the slider 32 slides in the slide groove 23, which can increase the stability of the movement of the L-shaped rod 31 and avoid the shaking of the L-shaped rod 31, thereby increasing the probability of alignment between the embedding block 13 and the embedding groove 71 and the alignment between the insertion rod 72 and the slot 14, making the fixing operation of the upper mold 2 and the lower mold 1 convenient and quick.

[0032] Working principle:

[0033] like Figure 1-Figure 4 As shown, use both hands to pinch the two groups of pressing plates 3 respectively, squeeze the spring 6 and the telescopic rod 5, so that the two fixed blocks 7 in the two groups are away from each other. After aligning the upper mold 2 with the lower mold 1, put the lower mold 1 on the upper side of the upper mold 2, so that the module 24 is embedded in the mold groove 11, ensure that the insert block 13 and the insert groove 71 are aligned, so that the insertion rod 72 is aligned with the slot 14, release the pressing plate 3, the spring 6 and the telescopic rod 5 are no longer under pressure, and the spring 6 and the telescopic rod 5 will rebound and move, driving the extension plate 4, the L-shaped rod 31 and the pressing plate 3 to move back, so that the insertion rod 72 is inserted into the slot 14, and the insert groove 71 wraps the outer wall of the insert block 13, and the upper mold 2 is fixedly connected to the upper side of the lower mold 1. When the telescopic rod 5 and the spring 6 are extended and retracted, the pressing plate 3 and the L-shaped rod 31 are moving at the same time, and one side of the L-shaped rod 31 slides against the inner wall of the rectangular groove 22, and the slider 32 slides in the slide groove 23, which can increase the stability of the movement of the L-shaped rod 31 and prevent the shaking of the L-shaped rod 31, thereby increasing the probability of the alignment of the insert block 13 and the insert groove 71 and the alignment of the insertion rod 72 and the slot 14, making the fixing operation of the upper mold 2 and the lower mold 1 convenient and quick. After the fixing is completed, the material is injected into the mold groove 11 through the injection port 21, and the module 24 can prevent the material from overflowing from the mold groove 11. After cooling and solidification, pinch the pressing plate 3 to disengage the insertion rod 72 from the slot 14, and the insert block 13 and the insert groove 71 are disengaged, and the upper mold 2 can be removed from the lower mold 1, and the knife and fork can be taken out.
