Detailed description of the preferred embodiments

The present invention is further described with reference to the accompanying drawings and specific embodiments, and it should be noted that any combination of the embodiments or technical features described below can be used to form a new embodiment without conflict. Except as specifically noted, the materials and equipment used in this example are commercially available.

Example one

The first purpose of the embodiment of the invention is to provide a bottom mold for a flying ring blow mold, namely a bottom mold structure in a blow mold in the blowing process of a flying ring integrated infusion container, which is used for matching with a flying ring structure to improve the processing efficiency of the flying ring integrated infusion container and reduce the probability of defective products.

Specifically, as shown in fig. 1 to 3, the flying ring blow-molded bottom mold 10 includes a bottom mold body 11, an annular groove 14 is formed in an upper end surface of the bottom mold body 11 and is used for accommodating the flying ring body, a first protrusion 12 and a second protrusion 13 are respectively formed inside and outside the annular groove 14, the first protrusion 12 and the second protrusion 13 extend above an upper end surface of the bottom mold body 11, the upper end surfaces of the first protrusion 12 and the second protrusion 13 are on the same plane, a tail pillar clearance 15 for accommodating a tail pillar of the flying ring is formed between the first protrusion 12 and the second protrusion 13, and the tail pillar clearance 15 is located in the annular groove 14.

The upper end surface of the bottom die body 11 corresponding to the inner part of the hanging ring can be integrally formed with a first protrusion 12, and then the first protrusion 12 extends towards the annular groove 14 to form an arc-shaped structure. Of course, the upper end surface of the bottom die body 11 corresponding to the interior of the hanging ring is not processed, and only the first protrusion 12 with an arc-shaped structure is arranged on the inner side of the annular groove 14, that is, the structure shown in fig. 1 of the present application. The second protrusion 13 is located at the opening of the arc-shaped structure, the annular groove 14 includes a first section 141, a second section 142, and a third section 143, where the first section 141 and the second section 142 are enclosed by the first protrusion 12 and the second protrusion 13 (the inner sidewall of one side of the first protrusion 12 and the sidewall of one side of the second protrusion 13 form the first section 141, the inner sidewall of the other side of the first protrusion 12 and the sidewall of the other side of the second protrusion 13 form the second section 142), and one end of the first section 141 and one end of the second section 142 are communicated and joined to form a junction, the junction is an axial plane, and both the first protrusion 12 and the second protrusion 13 are axially symmetric along the axial plane, that is, two portions of the first protrusion 12 located at both sides of the axial plane are symmetrically distributed with respect to the axial plane; the two portions of the second projection 13 located on both sides of the axial plane are symmetrically distributed with respect to the axial plane. Both ends of the third section 143 are respectively communicated with the other ends of the first section 141 and the second section 142.

The center of the tail stock clearance space 15 is located in the middle or rear of the axial face, although most of the area of the tail stock clearance space is located on the first or second section. Specifically, the method comprises the following steps: the tail post is kept away the vacancy 15 and is located the middle part of arc structure and the protruding directly ahead region of 13 of second, and this region preferred slightly is greater than the diameter of tail post, guarantees on the one hand that the tail post reachs this tail post smoothly and keeps away vacancy 15 among the blow molding process, and the effect of the protruding 13 centre gripping of first arch 12 and second is also through right the tail post under the second aspect, prevents the tail post slope, increases the process of rightting the tail post, improves work efficiency.

According to different requirements, the structure formed between the first section 141 and the second section 142 can be a V-shaped slot or a U-shaped slot; correspondingly, the structure of the second protrusion 13 may be a triangular protrusion (with a triangular cross section), and of course, the cross section may be any one of a rectangle, a trapezoid, a fan, a circle (or a circular arc), a polygon, and the like.

The cooperation of the first bulge 12 and the second bulge 13 is used for righting the tail column to avoid leakage dark marks; on the other hand, because the upper end surfaces of the two are positioned on the same horizontal plane (the horizontal plane is called as a supporting surface which is positioned above the upper end surface of the bottom die body, namely the supporting surface is higher than the upper end surface of the bottom die body), the stretching rod can stably reach the supporting surface in the stretching process of blow molding, so that a complete circle is formed at the bottom of the bottle blank (it can be understood that the lower end surface of the stretching rod is smaller than or equal to the supporting surface, so that the lower end surface of the stretching rod integrally falls into the supporting surface), and the phenomenon that the force is unbalanced due to the low depression on one side to cause defective products is avoided. In addition, the supporting surface is slightly higher than the upper end surface of the bottom die body 11, when the stretching rod stretches the bottle blank to reach the upper end surfaces of the first protrusion 12 and the second protrusion 13, the hanging ring body of the bottle blank falls into the annular groove 14 and cannot reach the bottom of the annular groove 14, the tail pillar falls into the tail pillar avoidance space 15 and cannot reach the bottom of the tail pillar avoidance space 15, the possibility that the hanging ring is bonded with the annular groove 14 and the tail pillar avoidance space 15 is prevented, and the probability of occurrence of defective products is further reduced.
