Description

Core for glass mold mouth mold

Technical Field

The utility model relates to a glass mold technical field, in particular to core for glass mold.

Background

The core is an important component of the glass bottle forming mold. In the process of producing glass bottles by a blowing-blowing method, in order to form a bottle mouth, a core is required to be inserted into a neck mold firstly, so that glass materials are preliminarily formed into a bottle mouth shape to form the bottle mouth, then the core exits from the neck mold, and the bottle mouth is blown in by air flow, so that the glass bottle body is formed.

A core for glass bottle mould bush as that CN212687889U disclosed, including core body and the core head of setting on the core body, overhead a plurality of gas holes that are provided with of core, the blind hole has been seted up to core body upper end, and the core head is inserted and is established in the blind hole, the through-hole has still been seted up to core body outer wall global, and the through-hole interpolation is equipped with the fixed pin, the fixed pin with the core head contacts fixedly, and core body and core head adopt different materials to make. In the use process, because the temperature of the molten glass material is higher, when the core exits from the neck mold, the end part of the core is easy to adhere to the glass material, so that the bottle mouth is deformed, the production quality of the glass bottle is influenced, and the production cost of an enterprise is increased.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a core for glass mold bush, this core can assist the drawing of patterns, avoids core head and glass material adhesion, prevents that the bottleneck from warping.

In order to achieve the technical purpose, the technical scheme of the utility model is that:

the core for the glass mold die comprises a core body, wherein a core head is arranged at the head end of the core body, a high-pressure air channel is arranged at the tail end of the core body, a plurality of air blowing holes are formed in the side wall of the core body and are communicated with the high-pressure air channel, internal cooling holes are formed in the core head and are communicated with the high-pressure air channel, an exhaust groove is formed in the end face of the core head and penetrates through the end part of the core head to be communicated with the internal cooling holes, and the width of the exhaust groove is 0.2-0.4mm.

Preferably, the width of the exhaust groove is 0.3mm.

The exhaust groove is an S-shaped exhaust groove.

The air blowing holes are inclined.

Six air blowing holes are formed, and the six air blowing holes are uniformly distributed on the side wall of the core body along the circumferential direction of the core body.

When the glass bottle neck forming die is used, a glass die primary die, a mouth die and the like are matched, a glass material enters the mouth die, a core head is punched into the mouth die to form a glass bottle neck, and when the core head is contacted with the glass material, the core is influenced by the glass material to be heated. When the core is withdrawn, the high-pressure air source blows the glass material through the high-pressure air channel and the air blowing hole, and the internal cooling hole is communicated with the high-pressure air channel, so that the core head is cooled simultaneously when the glass material is blown, the thermal shrinkage change of the head of the core is small, and the core head is convenient to demould; the exhaust groove is communicated with the internal cooling hole, so that when the glass material and the core print are blown and cooled, the exhaust groove is used for exhausting air, the adhesion of the glass material and the core print can be avoided, and the deformation of the bottle mouth can be prevented.

The utility model discloses a core for glass mold bush can not only assist the drawing of patterns, also avoids core head and glass material adhesion, prevents that the bottleneck from warping, improves glass bottle production quality, reduces the manufacturing cost of enterprise.
