Description

Technical Field

[0001] This utility model specifically relates to a two-color injection device. Background Technology

[0002] Plastic injection molding is the mainstream method for manufacturing plastic products today. There are many types of plastic injection molds, and mold designers must design different molds to meet the needs of different products. Generally, plastic injection molding can only inject one color or a single material at a time. However, as product requirements change, the industry also offers molds and machines for injection molding different plastics. The conventional two-color production method is achieved by setting a spacer plate between the upper and lower molds. However, using the same injection molding machine for two-color materials can easily cause color mixing, resulting in a longer production time and lower molding efficiency. Utility Model Content

[0003] In view of the shortcomings of the prior art, the technical problem to be solved by this utility model is to provide a two-color injection device.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a two-color injection device, including an injection device, a mold clamping device, and a flipping device. The mold clamping device includes a mold clamping frame, a mold clamping cylinder is provided at the bottom of the mold clamping frame, and a flipping plate is rotatably installed on the top of the mold clamping frame. Two upper templates are respectively installed on the upper and lower end faces of the flipping plate. The flipping device is installed on the top of the mold clamping frame to control the flipping plate to flip. The injection device is installed on one side of the mold clamping frame.

[0005] Preferably, the injection device includes an injection frame, on which two injection machines are mounted, and the injection ports of the two injection machines correspond to the feed ports of an upper template.

[0006] Preferably, the two injection machines are arranged in parallel.

[0007] Preferably, the two injection machines are arranged in a figure-eight pattern.

[0008] Preferably, the flipping device includes a flipping cylinder, the cylinder body of which is mounted on the mold clamping frame, and flipping shafts are provided at both ends of the flipping plate. The flipping shafts are rotatably mounted on the mold clamping frame, and the piston end of the flipping cylinder is connected to the flipping shafts.

[0009] Compared with the prior art, the present invention has the following advantages: the overall structure has a high degree of automation, and workers can carry out two-color production at a fixed workstation, which is simple to operate. Attached Figure Description

[0012] To make the above-mentioned features and advantages of this utility model more apparent and understandable, specific embodiments are described below in conjunction with the accompanying drawings for detailed explanation.

[0013] like Figure 1 As shown, a two-color injection device includes an injection device, a mold clamping device, and a flipping device. The mold clamping device includes a mold clamping frame 1, a mold clamping cylinder is provided at the bottom of the mold clamping frame 1, and a flipping plate 2 is rotatably installed on the top of the mold clamping frame 1. Two upper templates 3 are respectively installed on the upper and lower end faces of the flipping plate 2. The flipping device is installed on the top of the mold clamping frame 1 to control the flipping plate 2 to flip. The injection device is installed on one side of the mold clamping frame 1.

[0014] In this embodiment, the injection device includes an injection frame 4, on which two injection machines 5 are mounted. The injection ports of the two injection machines 5 correspond to the feed ports of an upper template 3, respectively. The feed ports of the two upper templates 3 are staggered to facilitate the installation of the injection machines 5.

[0015] The mold for this product consists of a bottom mold and two upper molds. Each injection unit corresponds to two upper molds, with the inlets of the two upper molds arranged left and right. The two upper molds are placed on the upper and lower ends of the flipping head, respectively. When the mold closing device fully closes one upper mold and the bottom mold, one injection unit will inject one color into the first mold. After injection, the mold closing device opens, and the flipping plate flips over to fully close the other upper mold and the bottom mold. At this time, the other injection unit will inject two colors into the mold. The overall structure has a high degree of automation, and operators can perform two-color production at a fixed workstation, making operation simple.

[0016] In this embodiment, the two injection machines 5 are arranged in parallel.

[0017] In this embodiment, the two injection units 5 are arranged in a figure-eight pattern.

[0018] In this embodiment, the flipping device includes a flipping cylinder 6, the cylinder body of which is mounted on the mold clamping frame 1, and flipping shafts are provided at both ends of the flipping plate 2. The flipping shafts are rotatably mounted on the mold clamping frame 1, and the piston end of the flipping cylinder 6 is connected to the flipping shafts.

[0019] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications, equivalent changes, and alterations made by those skilled in the art to the above embodiments based on the technical essence of the present utility model without departing from the content of the technical solution of the present utility model shall be within the scope of the present utility model.
