Technical Field

[0001] The utility model relates to the technical field of plastic cup production, in particular to a printing mold capable of preventing the mold from shifting. Background Art

[0002] Plastic cups refer to disposable containers used for beverages and tea. They are non-degradable products and are the main source of "white pollution". The largest users of disposable plastic cups are generally beverage stores, hot and cold drink stores, milk tea stores, hotels, restaurants and coffee shops, which provide various take-away drinks in plastic cups and on-site use. When producing plastic cups, printing molds are used to print designed text, pictures, labels and other graphics on the surface of the plastic cups.

[0003] The inventor discovered in his daily work that in the process of using a printing mold to print plastic cups, the air distributors in most of the existing printing molds on the market are installed with threads. Since the printing mold is in a rotating state during the printing process, the air distributor installed with the help of threads will become loose. Although some existing molds use threads with the same rotation direction as the printing mold to install the air distributor, the air distributor installed with the help of the above-mentioned threaded structure will rotate more tightly due to inertia, resulting in the problem of increased difficulty in disassembly during subsequent disassembly and maintenance. Utility Model Content

[0004] The purpose of the utility model is to solve the problem in the prior art that a gas distributor is installed by using a thread with the same rotation direction as the printing mold, but the gas distributor installed by means of the above-mentioned thread structure will rotate more tightly under the action of inertia, resulting in increased difficulty in subsequent disassembly and maintenance, and a printing mold is proposed to prevent the mold from shifting.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a printing mold for preventing mold displacement, comprising a mold body, a gas distributor and a limiting component, the gas distributor is installed on the inner wall of the mold body, the inner wall of the mold body is provided with a first bearing groove, the inner wall of the mold body is provided with a retaining ring groove, the inner wall of the mold body is provided with a retaining ring groove, the inner wall of the mold body is provided with a second bearing groove, the inner wall of the mold body is provided with an assembly groove, the gas distributor is located on the inner wall of the assembly groove, and the limiting component is arranged on the lower surface of the gas distributor;

The side surface of the angled push block is fixedly connected to a connecting pressure plate, and the side surface of the connecting pressure plate is fixedly connected to an anti-slip rubber strip.

[0008] Preferably, the extrusion unit also includes a guide rod, which is fixedly connected to the side surface of the connecting pressure plate, and a guide hole is opened on the side surface of the assembly block. The guide rod is slidably connected to the inner wall of the guide hole. Through the cooperation between the guide rod and the guide hole, the position of the connecting pressure plate can be constrained and the moving direction of the connecting pressure plate can be guided.

[0009] Preferably, there are two connecting sliders, which are symmetrically arranged with respect to the assembly block. Both ends of the connecting slider are chamfered. The position of the fixed pin can be restricted by the connecting slider with the cooperation of the compression spring, so that the fixed pin can be inserted into the slot when the gas distribution plate is assembled.

[0010] Preferably, there are two fixing pins, which are symmetrically arranged with respect to the assembly block. The fixing pins are slidably connected to the inner wall of the storage cavity. The fixing pins pass through the side surface of the assembly block. Through the cooperation between the fixing pins and the slots, the position of the gas distribution plate can be restricted under a limited state.

[0011] Preferably, the number of the compression springs is four, and the four compression springs are arranged diagonally with respect to the assembly block. The position of the connecting slider can be constrained by the compression springs to improve the stability of the connecting slider and reduce the probability of free movement of the connecting slider.

The pressure on the connecting slider loses the pressure applied to the compression spring, the compression spring loses the pressure and rebounds, and pushes the connecting slider to reset. The connecting slider simultaneously pushes the fixed pin to move. The fixed pin is inserted into the slot during the movement and cooperates with the assembly block to limit the position of the gas distributor. The installation operation of the gas distributor is then completed. By setting the limiting component, the position of the gas distributor in the installed state can be limited, thereby reducing the problem of loosening or over-tightening due to inertia when the gas distributor is only installed by threads, and further improving the stability of the gas distributor in the assembled state.

The assembly block 811 is located at the inner wall of the storage cavity 812 and is fixedly connected to a compression spring 815. The free end of the compression spring 815 is fixedly connected to the side surface of the connecting slider 813. A card slot 816 is provided on the inner wall of the mold body 1 located at the assembly groove 6, and the fixed bayonet 814 is plugged into the inner wall of the card slot 816.

[0027] The limiting component 8 also includes an extrusion unit 82, which includes an angled push block 822. A mounting hole 821 is provided on the side surface of the assembly block 811. The assembly block 811 is located on the inner wall of the mounting hole 821 and is slidably connected with the angled push block 822. The side surface of the angled push block 822 is fixedly connected with a connecting pressure plate 823, and the side surface of the connecting pressure plate 823 is fixedly connected with an anti-slip rubber strip 824.

[0028] Specifically, the extrusion unit 82 also includes a guide rod 825, which is fixedly connected to the side surface of the connecting pressure plate 823. A guide hole 826 is provided on the side surface of the assembly block 811. The guide rod 825 is slidably connected to the inner wall of the guide hole 826. Through the cooperation between the guide rod 825 and the guide hole 826, the position of the connecting pressure plate 823 can be constrained and the moving direction of the connecting pressure plate 823 can be guided.

[0029] Specifically, there are two connecting slide blocks 813 , which are symmetrically arranged with respect to the assembly block 811 , and both ends of the connecting slide blocks 813 are chamfered.

[0030] In this embodiment, the position of the fixed bayonet 814 can be limited by the engagement slider 813 in cooperation with the compression spring 815 , so that the fixed bayonet 814 can be inserted into the bayonet slot 816 when the gas distributor 7 is assembled.

[0031] Specifically, there are two fixing pins 814, which are symmetrically arranged with respect to the assembly block 811. The fixing pins 814 are slidably connected to the inner wall of the storage cavity 812. The fixing pins 814 pass through the side surface of the assembly block 811. Through the cooperation between the fixing pins 814 and the slots 816, the position of the gas distribution plate 7 can be restricted under a limited state.

[0032] In this embodiment, the number of the compression springs 815 is four, and the four compression springs 815 are arranged diagonally with respect to the assembly block 811 .

[0033] In this embodiment, the position of the connecting slider 813 can be constrained by the compression spring 815 to improve the stability of the connecting slider 813 and reduce the probability of the connecting slider 813 moving freely.

[0034] Specifically, there are four angled push blocks, and the four angled push blocks 822 are arranged diagonally with respect to the assembly block 811. The angled push blocks 822 abut against the inclined surface of the connecting slider 813.

[0035] Specifically, there are two guide rods 825 , and the two guide rods 825 are symmetrically arranged front and back with respect to the assembly block 811 .

[0036] In this embodiment: by opening a storage cavity 812 on the assembly block 811, the moving direction of the connecting slider 813 can be guided to ensure the stability of the connecting slider 813, and at the same time, one end of the compression spring 815 can be limited so that the compression spring 815 can only be deformed to one side.

[0037] Working principle: When installing the gas distributor 7, pinch the connecting pressure plates 823 on both sides of the assembly block 811, and the connecting pressure plates 823 cooperate with the bevel pressure blocks to squeeze the connecting slider 813, and the connecting slider 813 squeezes the compression spring 815, and the compression spring 815 is squeezed and deformed. At the same time, the connecting slider 813 is forced to pull the fixed bayonet 814 to move. When the connecting pressure plate 823 is squeezed and pressed against the surface of the assembly block 811, put the gas distributor 7 into the assembly groove 6, and rotate the connecting pressure plate 823 clockwise. The connecting pressure plate 823 cooperates with the bevel push block 822 and the assembly block 811 to rotate the gas distributor 7, and the gas distributor 7 is gradually screwed into the assembly groove 6. When the gas distributor 7 is tightened, the connecting pressure plate 823 is loosened, and the bevel push block 822 loses its engagement. The pressure applied by the connecting slider 813 causes the connecting slider 813 to lose the pressure applied to the compression spring 815, and the compression spring 815 loses the pressure and rebounds, pushing the connecting slider 813 to reset. The connecting slider 813 simultaneously pushes the fixed pin 814 to move, and the fixed pin 814 is inserted into the slot 816 during the movement, and cooperates with the assembly block 811 to limit the position of the gas distributor 7, and then the installation operation of the gas distributor 7 is completed. By setting the limiting component 8, the position of the gas distributor 7 in the installed state can be limited, thereby reducing the problem of loosening or over-tightening of the gas distributor 7 under the action of inertia when the gas distributor 7 is only installed by threads, and further improving the stability of the gas distributor 7 in the assembled state.
