Description

Technical Field

[0001] The utility model relates to the technical field of injection molds, in particular to a double-color injection mold with a spoon and cup cover. Background Art

[0002] Injection molds are very critical tools in the production of plastic products. They are used to transform thermoplastic or thermosetting plastic materials into plastic parts of various shapes and sizes through the injection molding process.

[0003] In the packaging of ready-to-eat foods, such as boxed yogurt, boxed ice cream, boxed jelly, etc., it is common to see a spoon attached to the cup lid. In the prior art, a pair of injection molds can simultaneously form the cup lid and the built-in spoon. However, in this case, the cup lid and the spoon are the same color. If the cup lid and the spoon are to be two different colors, two independent molds are usually required to produce components of different colors. This method will inevitably increase equipment investment and operating costs, while lengthening the production cycle, indirectly pushing up the overall manufacturing cost of the product.

DETAILED DESCRIPTION

[0030] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0031] like Figures 1 to 7 As shown, a two-color injection mold with a spoon cup cover of the utility model comprises:

[0032] A fixed mold assembly 1; a movable mold assembly 2, which is engaged with the fixed mold assembly 1 to form at least one group of spoon cavities and at least one group of cup cover cavities, and the spoon cavities correspond to the cup cover cavities one by one; a feed assembly 3, which is arranged on the fixed mold assembly 1, and the feed assembly 3 has a first material channel 4 and a second material channel 5 which are independent of each other, the first material channel 4 is connected with the spoon cavity, and the second material channel 5 is connected with the cup cover cavity, and is used for supplying two-color injection molding materials to flow into the spoon cavity and the cup cover cavity respectively; a first feed port 6, which is arranged on the end face of the fixed mold assembly 1 and is connected with the first material channel 4, and is used for supplying injection molding materials into the first material channel 4; a second feed port 7, which is arranged on the side of the fixed mold assembly 1 and is arranged vertically with the first feed port 6, and the second feed port 7 is used for supplying injection molding materials into the second material channel 5.

[0033] When the two-color injection mold in this scheme is working, first, through the mold closing process, the fixed mold component 1 and the movable mold component 2 are accurately connected to each other, and the spatial structure of the spoon cavity and the cup lid cavity are jointly defined. Then, one color of injection material is introduced through the first feed port 6 set on the end face of the fixed mold component 1, and flows smoothly into the spoon cavity along the first material channel 4. At the same time, the second color of injection material enters the mold through the second feed port 7 set on the side of the fixed mold component 1, and is directly filled into the cup lid cavity along the second material channel 5. This integrated two-color injection molding process ensures that the mold can simultaneously produce spoons and cup lids with two different colors in a single operation cycle, without relying on two sets of independent molds for step-by-step production, thereby greatly reducing the capital expenditure of equipment purchase and daily operation and maintenance, significantly reducing the production cycle time, and effectively reducing the manufacturing cost of unit products, thereby improving the overall economic benefits and market competitiveness.

[0034] In order to ensure that the two-color plastic material maintains ideal fluidity and fusion before being injected into the spoon cavity and the cup lid cavity respectively, the feed component 3 also includes a hot runner 8. The hot runner 8 is a heating system, which is integrated in the fixed mold component 1. Specifically, the first material channel 4 and the second material channel 5 are cleverly designed in the hot runner 8 structure. The hot runner 8 can accurately control the temperature of the plastic melt flowing therethrough to prevent the material from solidifying prematurely due to excessive cooling during the flow process, thereby ensuring that the material can be fully filled into each detail of the two-color injection mold of this scheme, improving the molding quality and surface finish of the product, and directly heating the injection molding material through the hot runner 8, thereby reducing the heat loss of the two-color injection molding material from the first material channel 4 to the spoon cavity and the second material channel 5 to the cup lid cavity, shortening the molding cycle and improving production efficiency.

[0035] In order to facilitate demoulding of the molded product, an ejection assembly 9 is also provided on the fixed mold assembly 1, and the ejection assembly 9 is used to eject the molded spoon and cup cover out of the fixed mold assembly 1.

[0036] Specifically, the fixed mold assembly 1 includes: a first push rod 10, a plurality of first push rods 10 are arranged in the fixed mold assembly 1, one end of each first push rod 10 is inserted in a spoon cavity and movably abuts against the molding spoon, and is used to eject the molding spoon out of the fixed mold assembly 1; a pushing plate 11, which is movably arranged in the fixed mold assembly 1, and one end of each first push rod 10 away from the spoon cavity is inserted on the pushing plate 11, and the pushing plate 11 drives the first push rod 10 to move, so that the first push rod 10 is movably abutted against the molding spoon and ejects the molding spoon out of the fixed mold assembly 1.

[0037] Specifically, the ejection assembly 9 also includes: a moving block 12, which is movably abutted against the molded cup cover and is used to eject the molded cup cover out of the fixed mold assembly 1; a moving seat 13, which is movably arranged on the fixed mold assembly 1, and a plurality of moving blocks 12 are arranged on the moving seat 13, and the moving seat 13 is used to drive the moving block 12 to move; a second ejector rod 14, a plurality of second ejector rods 14 are inserted on the pushing plate 11, and one end of each second ejector rod 14 away from the pushing plate 11 is inserted on the moving seat 13, and the movement of the second ejector rod 14 not only drives the moving seat 13 to move, but is also affected by the movement of the pushing plate 11. When the pushing plate 11 operates the first ejector rod 10 to eject the spoon, it will also link the second ejector rod 14, and then trigger the moving seat 13 and the moving block 12 thereon to cooperate, and finally realize the process of the moving block 12 smoothly pushing the molded cup cover out of the fixed mold assembly 1.

[0038] Specifically, the ejection assembly 9 also includes a driving member 15. A plurality of driving members 15 are arranged in the fixed mold assembly 1. The output ends of the driving members 15 are all connected to the push plate 11. The driving members 15 are used to drive the push plate 11 to move. The driving members 15 are preferably oil cylinders.

[0039] The specific steps of the ejection component 9 ejecting the formed spoon and cup lid from the fixed mold component 1 are as follows: after the mold opening instruction is started, the driving member 15 is immediately activated, pushing the push plate 11 to move forward. This action directly causes the first ejector rod 10 to move forward with the push plate 11. One end of them contacts the formed spoon and gradually pushes it out of the spoon cavity. At the same time, the second ejector rod 14 located on the push plate 11 is pushed forward and transmits force to the moving block 12 through the moving seat 13. The moving block 12 then slides forward and contacts the formed cup lid, ejecting the cup lid smoothly from the cup lid cavity. The whole process reflects the coordinated operation between the various components to ensure efficient and lossless demolding of the molded parts.
