[0004] The utility model aims to provide a hollow blow molding die head.

[0005] To achieve the above purpose, the utility model adopts the following contents:

[0006] A hollow blow molding die head comprises: a control core rod locking nut, a control core rod, a servo piston, a servo upper cylinder cover, a die adjustment nut, a transition ring and a shot upper cylinder cover; a servo upper cylinder cover is arranged at the upper end of the die head; a servo piston is arranged in the middle of the servo upper cylinder cover; the servo piston is hollow inside; a control core rod is arranged in the middle of the die head, and the control core rod extends upward into the servo piston; a shot upper cylinder cover is arranged on the control core rod at the bottom of the servo piston; a die adjustment nut is arranged on the control core rod in the servo piston; a transition ring is arranged at the bottom end of the die adjustment nut; and a control core rod locking nut is arranged on the control core rod at the upper end of the die adjustment nut.

[0007] Preferably, the control core rod is made of stainless steel.

[0008] Preferably, the control core rod locking nut is threadedly connected to the control core rod.

[0009] Preferably, the servo upper cylinder cover and the injection upper cylinder cover are both made of stainless steel.

[0010] The utility model has the following advantages:

[0011] The device has a simple structure and reasonable design. The servo piston is thickened and space is processed inside. The die adjustment nut, transition ring, control mandrel locking nut, and the upper end of the control mandrel are placed inside the servo piston and do not exceed the servo cylinder cover. This saves external space and reduces the height of the overall die head and the height of the entire equipment. It does not need to be disassembled during shipment and does not exceed the height after loading, which improves shipment efficiency and reduces costs.

[0012] The above description is only an overview of the technical solution of the utility model. In order to more clearly understand the technical means of the utility model and implement it according to the contents of the specification, the following is a detailed description of the preferred embodiments of the utility model in conjunction with the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] The specific implementation of the utility model is further described in detail below with reference to the accompanying drawings.

[0014] Figure 1 The utility model is a structural schematic diagram of a hollow blow molding die head.

[0015] In the figure, each reference numeral is:

[0016] 1-control core rod locking nut, 2-control core rod, 3-servo piston, 4-servo upper cylinder cover, 5-die adjustment nut, 6-transition ring, 7-injection upper cylinder cover. DETAILED DESCRIPTION

[0017] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. 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.

[0018] 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.

[0019] 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.

[0020] 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.

[0021] like Figure 1 As shown, a hollow blow molding die head includes: a control core rod locking nut 1, a control core rod 2, a servo piston 3, a servo upper cylinder cover 4, a die adjustment nut 5, a transition ring 6 and an injection upper cylinder cover 7; a servo upper cylinder cover 4 is arranged at the upper end of the die head; a servo piston 3 is arranged in the middle of the servo upper cylinder cover 4; the servo piston 3 is hollow inside; a control core rod 2 is arranged in the middle of the die head, and the control core rod 2 extends upward into the servo piston 3; an injection upper cylinder cover 7 is arranged on the control core rod 2 at the bottom of the servo piston 3; a die adjustment nut 5 is arranged on the control core rod 2 in the servo piston 3; a transition ring 6 is arranged at the bottom end of the die adjustment nut 5; a control core rod locking nut 1 is arranged on the control core rod 2 at the upper end of the die adjustment nut 5.

[0022] Furthermore, the control core rod 2 is made of stainless steel.

[0023] Furthermore, the control mandrel locking nut 1 is threadedly connected to the control mandrel 2 .

[0024] Furthermore, the servo upper cylinder cover 4 and the injection upper cylinder cover 7 are both made of stainless steel.

[0025] Working principle of the device: The device has a simple structure and reasonable design. The servo piston 3 is thickened and a space is processed inside. The die adjustment nut 5, transition ring 6, control mandrel locking nut 1, and the upper end of the control mandrel 2 are all placed inside the servo piston 3 and do not exceed the servo cylinder cover 4. This saves external space and reduces the height of the overall die head and the height of the entire equipment. It does not need to be disassembled during shipment and does not exceed the height after loading, which improves shipment efficiency and reduces costs.

[0026] The technical features of the above-described embodiments may be arbitrarily combined.
