[0024] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings, further illustrating the present invention.

[0025] First, combine Figures 1-5 The lip mold mechanism for fixing the preform handle according to an embodiment of the present utility model is used in the production and manufacturing of preform 2 and has a wide range of applications.

[0026] like Figures 1-5 As shown, the lip mold mechanism for fixing the preform handle in this embodiment of the present invention includes: a lip mold body 1 and a handle insert 5.

[0027] Specifically, such as Figures 1-5As shown, in this embodiment, a molding cavity 11 is provided in the middle of the lip mold body 1 for molding the bottle mouth of the preform 2; a handle insert 5 is provided on the lip mold body 1 and corresponds to the position of the handle 3 of the preform 2. The handle insert 5 is used for molding the handle 3 and fixing the handle 3. In this embodiment, the handle insert 5 participates in the entire injection stretch blow molding process of the preform 2 together with the lip mold body 1. Through the handle insert 5, the deformation of the handle 3 during injection molding can be prevented; the position of the handle 3 can be prevented from changing when the lip mold moves with the preform 2, which would cause damage to the blown mold cavity; and the position of the handle 3 can be prevented from being moved when the mold is opened.

[0028] Furthermore, such as Figures 1-5 As shown, in this embodiment, the handle insert 5 includes: a main body 51, the top end of which is fixed to the lip mold body 1, and the main body 51 is fixed to the lip mold body 1 by bolts 4, which facilitates installation, disassembly and replacement; a molding part 52, which is disposed at the bottom end of the main body 51, and is used to mold the handle 3. The inner side of the molding part 52 is arc-shaped to correspondingly mold an arc-shaped handle 3, which is smoother and more beautiful, fits the user's palm and improves the user's grip experience; and a pair of edging parts 53, which are respectively disposed on both sides of the molding part 52. The pair of edging parts 53 respectively hug the two sides of the handle 3 to fix the handle 3. The edging parts 53 limit the handle 3 to prevent the handle 3 from deforming and changing position.

[0029] Furthermore, in this embodiment, the handle insert 5 is made of S136 stainless steel and heat-treated to a hardness of 50 degrees to prevent damage due to friction.

[0030] Furthermore, such as Figures 1-5 As shown, in this embodiment, the lip mold body 1 is composed of a pair of mirror-symmetrical lip molds 13, and the handle insert 5 is composed of a pair of mirror-symmetrical insert bodies 54. The pair of insert bodies 54 are respectively disposed on the pair of lip molds 13. When the pair of lip molds 13 are closed, the pair of insert bodies 54 will close. When the pair of lip molds 13 are separated, the pair of insert bodies 54 will separate.

[0031] Furthermore, such as Figures 1-5 As shown, in this embodiment, the connecting edges of a pair of lip templates 13 are provided with inclined grooves in opposite directions. The inclined grooves of the pair of lip templates 13 form a V-groove 12. The V-groove 12 is used for the mold opening of the pair of lip templates 13. When the preform 2 is opened after injection stretch blow molding, the external insert is inserted into the V-groove 12 to facilitate the mold opening of the pair of lip templates 13. In this embodiment, there are two V-grooves 12, which are symmetrically arranged at both ends of the lip mold body 1, resulting in a better mold opening effect.

[0032] Working principle: At the injection molding station, the handle insert 5 participates in the molding of the preform 2 and the handle 3 along with the lip mold body 1. The edge 53 of the handle insert 5 fixes the molded handle 3. The lip mold body 1, along with the handle insert 5 and the molded preform 2 and handle 3, enters the temperature adjustment station and the blow molding station in sequence for temperature adjustment and stretch blow molding. At the demolding station, a pair of lip mold plates 13 open, and a pair of insert bodies 54 separate accordingly. The bottle with handle 3 leaves the mold, and production is completed.

[0033] Above, refer to Figures 1-5 The present invention describes a lip mold mechanism for fixing the handle of a preform according to an embodiment of the present invention. By adding a handle insert, the handle can be fixed throughout the process, which significantly reduces the product defect rate.
