Description

Technical Field

[0001] The utility model relates to the technical field of injection mold cavity arrangement, in particular to an arrangement structure of a key cap injection mold cavity. Background Art

[0002] A keycap refers to a small plastic cap-shaped component on the top of each key on a keyboard. The keycap is formed by injection molding. When the keycap is injection molded, an arrangement structure is required to arrange the injection mold cavity. A large number of keycaps can be produced in a short time, which greatly improves production efficiency and reduces production costs. In the prior art, when arranging the keycap injection mold cavity, the keycap injection fixed mold is usually arranged in an up and down arrangement. However, one injection mold is fixed on the machine, and the vibration generated by the opening and closing of the other mold tens of thousands of times causes the mold to gradually move under the influence of gravity, thereby causing the upper and lower side wall dimensions of the keycap product to exceed the specification, affecting the aesthetics of the keycap product and the entire keyboard arrangement. For this reason, the utility model rotates the keycap injection mold cavity 90 degrees along the vertical plane to reduce the impact on the upper and lower side wall dimensions. Summary of the invention

[0003] The disclosed embodiment relates to an arrangement structure of a keycap injection mold cavity, which prevents the original fixed mold arrangement in a vertical or horizontal position from rotating, so that the main pipe and the guide pipe drive the fixed mold at the side end of the diversion pipe to rotate vertically 90 degrees, and adjust the original product line to reduce the cost of drastically changing the product line. At the same time, when the rotated fixed mold is injected, the upper and lower side wall dimensions of the keycap product will not exceed the specification, and the aesthetics of the keyboard layout will not be affected.

[0004] According to a first aspect of the present disclosure, there is provided a layout structure of a keycap injection mold cavity, specifically comprising: a main pipe, wherein a guide pipe is installed at the inner end of the main pipe; a fixed carrier is installed at the outer side of the main pipe; a groove is provided at the top of the fixed carrier, a driving cylinder is installed inside the groove, and a support plate is installed on the output end of the driving rod in the groove at the top of the fixed carrier; a support frame is installed at the top and bottom of the fixed carrier; both ends of the support frame are arc-shaped structures, and guide grooves are provided on the support frame.

[0005] Furthermore, the outer side of the flow guide pipe is connected to a shunt pipe; a fixed mold is installed on the side end of the shunt pipe; and the interior of the shunt pipe is connected to the mold cavity inside the fixed mold.

[0006] Furthermore, a guide plate is installed on the side of the support plate; the side end of the guide plate is an inclined structure, and a guide wheel is rotatably installed on the inner side of the guide plate; the inner side of the guide plate and the guide wheel are slidably installed on the outer side of the fixed mold.

[0007] Furthermore, the two ends of the guide rod are slidably mounted on the inner end of the guide groove; the guide rod is a cylindrical structure, and limiting protrusions are provided at both ends of the guide rod; a fixed side plate 1 is mounted on the outer side of the guide rod; and a collection box is mounted on the outer side of the fixed side plate 1.

[0008] Furthermore, a collecting hood is installed on the side end of the fixed side plate; the outer end of the collecting hood is a conical structure; an air suction pump is installed on the top of the collecting box, and an air flow tube is installed on the output end of the top of the air suction pump; the side end of the air flow tube is installed on the collecting hood.

[0009] Furthermore, a fixed side plate 2 is installed on the outer side of the guide rod; a jet hood is installed on the side end of the fixed side plate 2; the side end of the jet hood is flat, and the jet hood faces the mold cavity inside the fixed mold, and a power module is installed at the bottom of the jet hood.

[0010] Compared with the prior art, the utility model has the following beneficial effects:

[0011] When the utility model is in use, the fixed mold is driven to rotate vertically 90 degrees by rotating the guide tube, thereby reducing the problem of over-specification of the upper and lower side walls during keycap injection molding. When the keycap injection cavity is arranged, the original vertical position of the fixed mold arrangement is rotated, so that the main pipeline and the guide tube drive the fixed mold at the side end of the diversion tube to rotate vertically 90 degrees to a vertical horizontal position, and the original product line is adjusted to reduce the cost of significantly changing the product line. At the same time, when the rotated fixed mold is injected, the upper and lower side walls of the keycap product will not exceed the specification, and the aesthetics of the keyboard layout will not be affected.

[0012] In addition, the residues in the mold cavity are cleaned by using a jet hood and a collecting hood. After one period of keycap injection molding, the guide rod is pushed to move along the guide groove on the support frame, so that the jet hood sprays air to blow and clean the residues in the mold cavity inside the fixed mold, and the collecting hood collects the blown air flow and the debris carried by the air flow at the same time, thereby reducing the accumulation of residues after multiple injection molding and affecting the quality of keycap injection molding.
