DETAILED DESCRIPTION
[0026] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0027] The utility model Figure 1 The direction shown is the reference orientation in the up and down directions, with the position close to the forefoot of the human body as the front of the shoe, and the position close to the arch of the human foot as the back of the shoe.
[0028] like Figure 1-Figure 5 As shown, a color-contrast mold for shoes includes a first template 10, a first color isolation plate 20, a cooling plate 30, a second color isolation plate 40 and a second template 50 which are connected by bolts from top to bottom. The first template 10 has two first molding chambers, and the second template 50 has two second molding chambers. The two first molding chambers and the two second molding chambers are respectively arranged in a one-to-one correspondence. The two first molding chambers are used to form the upper part of a pair of shoes, namely the upper part of the left foot and the upper part of the right foot, and the two second molding chambers are used to form the lower part of a pair of shoes.
[0029] A first feed hole 21 is provided on the first color isolating plate 20, and a first feed channel is provided inside the first color isolating plate 20. The first feed hole 21 is connected to the first feed channel, and the first feed channel is connected with a first feed column 61 for feeding into the first molding chamber and a second feed column 62 for feeding into the second molding chamber; in this embodiment, two first feed columns 61 and two second feed columns 62 are connected to the first connecting channel, and the two first feed columns 61 are respectively arranged in a one-to-one correspondence with the two first molding chambers, and the two second feed columns 62 are respectively arranged in a one-to-one correspondence with the two second molding chambers; molding material is injected into the two first molding chambers respectively through the two first feed columns 61 in a one-to-one correspondence, and molding material is injected into the two second molding chambers respectively through the two second feed columns 62 in a one-to-one correspondence.
[0030] In this embodiment, the first feed channel includes a first main channel 71, two first branch channels 72 and two second branch channels 73, the two first branch channels 72 are connected to both sides of the first main channel 71 respectively, and the two second branch channels 73 are connected to both sides of the first main channel 71 respectively, and the two first feed columns 61 are connected to the two first branch channels 72 respectively, and the two second feed columns 62 are connected to the two second branch channels 73 respectively; the distance between the first feed column 61 and the first feed hole 21 is greater than the distance between the second feed column 62 and the first feed hole 21. Since the second feed column 62 needs to pass through the cooling plate 30 and the second color isolation plate 40 to enter the second molding chamber, the distance between the second feed column 62 and the first feed hole 21 is shortened so that the first feed column 61 and the second feed column 62 can inject molding material into the molding chamber at the same time, so that the upper and lower parts of the formed shoes correspond to each other.
[0031] The second color separator 40 is provided with a second feed hole 41, and the second color separator 40 has a second feed channel, the second feed hole 41 is connected to the second feed channel, and the second feed channel is connected with a third feed column 63 for feeding into the first molding chamber and a fourth feed column 64 for feeding into the second molding chamber; in this embodiment, the second connecting channel is connected with two third feed columns 63 and two fourth feed columns 64, and the two third feed columns 63 are respectively arranged in a one-to-one correspondence with the two first molding chambers, and the two fourth feed columns 64 are respectively arranged in a one-to-one correspondence with the two second molding chambers. The molding material is injected into the two first molding chambers in a one-to-one correspondence through the two third feed columns 63, and the molding material is injected into the two second molding chambers in a one-to-one correspondence through the two fourth feed columns 64.
[0032] The second feed channel includes a second main channel 81, two third branch channels 82 and two fourth branch channels 83, the two third branch channels 82 are connected to both sides of the second main channel 81 respectively, the two fourth branch channels 83 are connected to both sides of the second main channel 81 respectively, the two third feed columns 63 are connected to the two third branch channels 82 respectively, the two fourth feed columns 64 are connected to the two fourth branch channels 83 respectively, the distance between the third feed column 63 and the second feed hole 41 is greater than the distance between the fourth feed column 64 and the second feed hole 41; since the fourth feed column 64 needs to pass through the cooling plate 30 and the second color isolation plate 40 to enter the first molding chamber, the distance between the fourth feed column 64 and the second feed hole 41 is shortened so that the feeding speeds of the third feed column 63 and the fourth feed column 64 are consistent.
[0033] The first feed column 61 is located in the first molding chamber away from the first feed hole 21, the third feed column 63 is located in the first molding chamber close to the first feed hole 21, the second feed column 62 is located in the second molding chamber away from the first feed hole 21, and the fourth feed column 64 is located in the second molding chamber close to the first feed hole 21. The molding material injected through the first feed column 61 and the second feed column 62 is used to form the front part of the shoe, and the molding material injected through the third feed column 63 and the fourth feed column 64 is used to form the rear part of the shoe.
[0034] As a preferred mode of the present embodiment, each first branch channel 72, each second branch channel 73, each third branch channel 82 and each fourth branch channel 83 is connected with a flow control bolt 91. The flow rate of the branch channel is adjusted by adjusting the flow control bolt 91. On the one hand, the proportion of molding material at the front and the rear of the shoe is controlled, that is, the ratio of the two colors on the shoe is controlled. On the other hand, the contrasting color mold can be suitable for shoes with different color ratios, thereby improving the applicability of the contrasting color mold and saving production costs.
[0035] As a preferred mode of this embodiment, the central axis of the first feed hole 21 is gradually inclined toward the first main channel 71 from one end away from the first main channel 71 to the other end, and the central axis of the second feed hole 41 is gradually inclined toward the second main channel 81 from one end away from the second main channel 81 to the other end; so that the molding material can flow into the main channel faster when it is injected through the feed hole.
[0036] As a preferred mode of this embodiment, two temperature sensing holes 31 arranged opposite to each other are provided on the cooling plate 30 , and the temperature sensing holes 31 are used to place temperature sensing devices so as to monitor the temperature of the cooling plate 30 .
[0037] The molding process of the contrasting color mold is as follows: two different colors of molding materials are respectively injected into the first feed hole 21 and the second feed hole 41 through a conventional EVA two-color injection molding machine, one color of molding material is injected into the front of the first molding chamber through the first feed column 61, and injected into the front of the second molding chamber through the second feed column 62, and the other color of molding material is injected into the rear of the second molding chamber through the third feed column 63, and injected into the rear of the first molding chamber through the fourth feed column 64. The first molding chamber and the second molding chamber The two molding materials in the room collide with each other when they come into contact, and the two colors of molding materials fuse with each other. Then, the first color isolation plate 20, the cooling plate 30 and the second color isolation plate 40 are removed, and the first template 10 and the second template 50 are molded together. They are heated and foamed by a heating foaming machine, and then cooled and molded by a conventional cold setting line to form shoes, and a gradient color is formed on the shoes. The speed at which the molding machine injects the molding materials determines the impact force of the two molding materials, thereby controlling the amount of mutual fusion of the two colors, that is, controlling the size of the gradient color area on the shoe.
[0038] In summary, the mold can inject two different colors of molding materials into the molding chamber at the same time, so as to form a shoe with a gradient color in the middle and different colors at the front and back.
[0039] The specific implementation methods described above further illustrate the purpose, technical solutions and beneficial effects of the utility model in detail. It should be understood that the above description is only the specific implementation method of the utility model and is not used to limit the protection scope of the utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the utility model should be included in the protection scope of the utility model.
