[0006] The bottle stripping assembly comprises a demoulding guide rod connected to the frame, a demoulding fixed plate is connected to the top of the demoulding guide rod, a demoulding oil cylinder is connected to the top surface of the demoulding fixed plate, a demoulding movable plate is sleeved on the demoulding guide rod, a piston rod of the demoulding oil cylinder is connected to the demoulding movable plate to control the lifting of the demoulding movable plate, and vertical plug plates are connected to the left and right sides of the demoulding movable plate, and the bottom of the plug plate is a triangular structure with a wide top and a narrow bottom;

[0007] The demoulding oil cylinder controls the demoulding movable plate to move downward, and inserts the insert plate into the triangular groove to separate the left half mold and the right half mold, thereby causing the bottle to fall off.

[0008] Preferably, the demoulding guide rods are four in number and are arranged in four directions: front, back, left, and right.

[0009] The utility model has a simple structure, relies on the insertion of the inserting plate into the triangular groove to separate the left half mold and the right half mold so that the bottle falls off, and after the inserting plate is separated from the triangular groove, the left half mold and the right half mold are automatically reset under the pulling of the spring, and the whole mechanical structure can still work stably after long-term use. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Among them: 1—clamping mold; 11—left half mold; 12—right half mold; 13—triangular groove; 2—bottle ejection assembly; 21—ejection guide rod; 22—ejection fixed plate; 23—ejection cylinder; 24—ejection movable plate; 25—insert plate. DETAILED DESCRIPTION

[0013] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0014] like Figure 1 and Figure 2 As shown, the utility model provides a bottle-removing mechanism for a bottle blowing machine, comprising a clamping mold 1 arranged below a frame and a bottle-removing assembly 2 arranged above the frame;

[0015] The clamping mold 1 includes a left half mold 11 and a right half mold 12, the left half mold 11 and the right half mold 12 are tightened by a spring, and a triangular groove 13 is provided at the intersection of the left and right top surfaces of the left half mold 11 and the right half mold 12;

[0016] The bottle stripping assembly 2 comprises a demoulding guide rod 21 connected to the frame, a demoulding fixed plate 22 is connected to the top of the demoulding guide rod 21, a demoulding oil cylinder 23 is connected to the top surface of the demoulding fixed plate 22, a demoulding movable plate 24 is sleeved on the demoulding guide rod 21, a piston rod of the demoulding oil cylinder 23 is connected to the demoulding movable plate 24 to control the lifting of the demoulding movable plate 24, and vertical plugging plates 25 are connected to the left and right sides of the demoulding movable plate 24, and the bottom of the plugging plate 25 is a triangular structure with a wide top and a narrow bottom;

[0017] The demoulding cylinder 23 controls the demoulding movable plate 24 to move downwards and insert the insert plate 25 into the triangular groove 13 to separate the left half mold 11 and the right half mold 12, thereby causing the bottle to fall off.

[0018] In the above solution, the number of the demoulding guide rods 21 is four, which are arranged in four directions: front, back, left, and right.

[0019] In the utility model, the preform is injection molded between the left half mold 11 and the right half mold 12 at the beginning, and the bottle is blown after the subsequent bottle blowing stage. The edge of the blown bottle is clamped by the left half mold 11 and the right half mold 12. If the bottle is to fall off, the left half mold 11 and the right half mold 12 need to be opened. Thereafter, the insert plate 25 is inserted into the triangular groove 13 to separate the left half mold 11 and the right half mold 12 to make the bottle fall off. After the insert plate 25 is separated from the triangular groove 13, the left half mold 11 and the right half mold 12 are automatically reset under the pull of the spring, and the insert plate 25 is driven to rise and fall and reset through a series of mechanisms above, and then the preform injection molding and subsequent bottle blowing stages between the left half mold 11 and the right half mold 12 are repeated. The entire bottle removal structure is simple and reliable, not prone to failure, and can be produced for a long time.

[0020] The above is only a preferred implementation mode of the utility model, and does not impose any form of limitation on the utility model. Any simple modification, equivalent change or modification made to the above embodiments based on the technical principle of the utility model still falls within the scope of the technical solution of the utility model.
