Obviously, the described embodiments are part of the embodiments of the utility model, not all of the 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.

[0017] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0018] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0019] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0020] like Figure 1 As shown, a high-speed injection molding device for thin-walled parts includes: a machine body 1, a mold clamping device 2, a locking valve 3, an ejection valve 4, a feeding valve 5, a shot valve 6, an electric control cabinet 7, a guide rail 8, a quantitative feeding mechanism 9, a hopper 10 and a nitrogen cylinder 11; a locking valve 3 is arranged at the left bottom end of the machine body 1; an ejection valve 4 is arranged at the upper end of the locking valve 3; a shot valve 6 is arranged at the middle bottom end of the machine body 1; a feeding valve 7 is arranged at the upper end of the shot valve 6; an electric control cabinet 7 is arranged on the right side of the machine body 1; a guide rail 8 is arranged on the right side of the upper end of the machine body 1; a quantitative feeding mechanism 9 is arranged at the upper end of the guide rail 8; a hopper 10 is arranged at the upper end of the quantitative feeding mechanism 9; a nitrogen cylinder 11 is arranged on one side of the hopper 10, and the nitrogen cylinder 11 and the quantitative feeding mechanism 9 are used in coordination; a mold clamping device 2 is arranged on the left side of the upper end of the machine body 1; the quantitative feeding mechanism 9 and the mold clamping device 2 are connected through a barrel 12.

[0021] Furthermore, the mold clamping device 2 includes a display screen 21, a control console 22, a safety door 23 and a mold clamping ejection mechanism 24; the display screen 21 is arranged at the upper right end of the mold clamping device 2; the control console 22 is arranged on the mold clamping device 2 at the bottom end of the display screen 21; the mold clamping ejection mechanism 24 is arranged on the left side of the mold clamping device 2; and the safety door 23 is arranged on the mold clamping device 2 between the mold clamping ejection mechanism 24 and the control console 22.

[0022] Furthermore, the mold clamping device 2 is fixed to the machine body 1 by bolts.

[0023] Furthermore, the guide rail 8 is fixed to the body 1 by bolts.

[0024] Working principle of this device: The filling time of thin-wall injection molding is very short, and many filling times are less than 0.5 seconds. Therefore, a very fast filling mold must be used. During the entire injection molding process of thin-walled products, the pressure and speed should be controlled independently at the same time. Conventional injection molding machines are no longer applicable, and electric motors or hybrid electric and nitrogen accumulator machines must be relied on to meet this requirement.

[0025] High-speed injection molding technology is mainly divided into full hydraulic high-speed machine, full electric high-speed machine and electro-hydraulic composite high-speed machine according to the driving mode. At present, our company has full electric high-speed machine and electro-hydraulic composite high-speed machine that can be used for injection molding products with thin walls below 0.5MM.

[0026] High-speed injection molding machines use three-axis linkage and mold opening (synchronous mold opening, synchronous material storage, ejection while mold opening, etc.). For example, the molding time of a product using an ordinary injection molding machine is 10 seconds. The high-speed injection molding machine uses the principle of three-axis linkage to greatly shorten the molding time to about 6 seconds, subtracting two small steps but increasing the time by about half the speed.

[0027] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0028] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
