AI Technical Summary
In current glass bottle production, the large contact area between the mouth ring and the punch leads to severe wear, causing iron powder to stick to the bottle mouth and form black spots, affecting the quality and pass rate of glass products.
Design a mouth ring and punch mating part for glass bottle forming. The upper part of the mouth ring is a flared mouth that is smaller at the top and larger at the bottom, which reduces the contact area with the punch and improves the wear problem.
By reducing the contact area between the mouth ring and the punch, wear is reduced, iron powder adhesion is decreased, and the quality and product qualification rate of glass products are improved.

Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to glass bottle production mould field especially relates to a glass bottle forming mouth ring and punch cooperation position. BACKGROUND
[0002] The existing glass bottle production process mainly includes: batching, melting, forming, annealing, and the specific process includes: raw material→batching→kiln melting→to production line material channel→material basin cutting (cut into material drops) →material distribution (downloading) →initial mold forming→mold forming. The black spot defect on the glass bottle product seriously affects the glass quality (such as bird's nest bottle), and makes the finished product qualified rate decrease. Through the classification analysis of the factors causing black spots, it is found that the contact surface of the mouth ring and the punch (the punch is used for inserting the glass liquid from the bottom into the mold, forming the embryo of the glass bottle cavity and the bottle mouth) is large and wears fast, and the iron powder generated by it sticking to the bottle mouth is a main factor causing black spots. Therefore, the mouth ring structure needs to be further modified to reduce the contact area with the punch. SUMMARY
[0003] The utility model wants to solve the technical problem, in order to provide a glass bottle forming mouth ring and punch cooperation position.
[0004] The utility model is realized thus:
[0005] A glass bottle forming mouth ring and punch cooperation position, including the mouth ring that sets in the mouth die and is located below the mouth die, and the punch that is in the center of the mouth ring and is matched with the mouth ring and moves up and down, the contact surface of the punch on the mouth ring is only the most upper end opening.
[0006] Further, the upper part of the mouth ring is a horn mouth that is small at the top and large at the bottom.
[0007] Still further, the two side edges of the horn mouth are straight line segments or arc segments.
[0008] The utility model has the advantages that the upper part of the mouth ring is turned into a horn mouth, the contact area with the punch is reduced, the wear between the mouth ring and the punch is reduced, the black spots caused by the iron powder sticking to the bottle mouth due to wear are finally improved, the quality of the glass product is improved, and the product qualified rate is improved. BRIEF DESCRIPTION OF DRAWINGS
[0009] The utility model will be further described below in combination with the embodiments with reference to the drawings.
[0010] Figure 1 It is the structure schematic diagram of the utility model.
[0011] Figure 2 It is the structure schematic diagram of prior art. DETAILED DESCRIPTION
[0012] In the description of the utility model, it is understood that the description of indicating the orientation or position relation is based on the orientation or position relation shown in the drawings, and is only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the indicated device or element must have a particular orientation, a particular orientation and operation, and therefore cannot be understood as a limitation on the protection scope of the utility model.
[0013] In the description of the utility model, it should be explained that, unless otherwise specified and limited, the terms "arrangement", "connection", "connection" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected, it can be mechanically connected, or electrically connected, it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For ordinary skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.
[0014] The technical scheme of the utility model is as follows:
[0015] Please refer to Figure 1 The utility model discloses a mouth ring and punch cooperation position for glass bottle forming, which comprises a mouth ring 1 arranged in a mouth die and located below the mouth die, and a punch 2 moving up and down at the center of the mouth ring 1 and cooperating with the mouth ring, wherein the upper part of the mouth ring is a horn mouth 11 with a small upper part and a large lower part.
[0016] In one embodiment, the FJ1-3 machine in the factory is used to produce bird's nest bottle AC10929. The punch 2 comprises a punch end 21 gradually widened in an arc shape from top to bottom, and a punch step 22 protruding below the punch end 21, wherein the punch end 21 and the punch step 22 are formed around the circumference of the punch 2 and are integrally formed. The existing technology uses a mouth ring 1' with a cavity 11' for the up and down movement of the punch, and a mouth ring step 12' formed around the cavity, as shown in Figure 2 In this case, the contact surface of the punch 2 and the mouth ring 1' is the side wall of the mouth ring step, and the contact surface is large, which is easy to wear when the punch 2 moves up and down, and the iron powder generated by wear adheres to the bottle mouth to form black spots. After modification, the upper part of the mouth ring 1 is formed into a horn mouth 11 with a smooth transition and gradually widened (the arc is outward) from top to bottom, so that the contact surface of the punch is only the upper end of the horn mouth, reducing the black spots generated by the friction between the punch and the mouth ring.
[0017] Although the specific embodiments of the present application are described above, those skilled in the art should understand that the specific embodiments described by us are only illustrative, not for limiting the scope of the present application, and equivalent modifications and changes made by those skilled in the art in accordance with the spirit of the present application should be covered within the scope of the claims of the present application.
