Description

Clamp for maintaining glass mold

Technical Field

The invention belongs to the technical field of tool fixtures, and particularly relates to a fixture for maintaining a glass mold.

Background

The above-mentioned glass mold is mainly referred to as a molding die, but is not absolutely limited to molding, and may include, for example, a blank mold. Known glass molds for manufacturing glass containers (such as beer bottles, red wine bottles, soda bottles, cosmetics bottles for daily use, seasoning bottles, and various beverage bottles, etc.) are generally of a two-mold structure symmetrical to each other, and for this purpose, reference is made to chinese patent application publication No. CN101298355A (mold for manufacturing glass containers), CN101298356A (mold for manufacturing glass containers), CN101298357A (mold for processing glass containers), CN101298358A (mold for processing glass containers), CN101298359A (mold for processing glass containers), CN101941791A (mold for manufacturing glass containers for bottles and cans), grant publication No. CN102515471B (mold for manufacturing glass containers for bottles and cans), and US patent No. US2006/0213632a1 (glass molding mold), and so forth.

As still known in the art, the glass mold is expensive due to severe requirements for materials and processes in the whole process of processing, and relatively many process steps are added, and in view of saving resources and saving the use cost of the mold, the glass mold (primary mold, forming mold), the die, or even the punch, the bottom mold, etc. need to be repaired according to specific situations, such as repairing damaged parts, spray welding seam (mold shallow crack) parts and all joint parts, trimming the joint parts of the primary mold and the blank, turning and polishing the joint parts of the die, lettering and knurling the bottom mold plate, etc. The more frequent or more conventional maintenance of the glass mold forming mold is to polish a cavity opening of a mold cavity (which is conventionally called as a cavity head and neck opening or a cavity upper opening) and a cavity (which is conventionally called as a cavity lower opening) positioned in a matching groove of a bottle bottom mold, so that the quality of a glass product is ensured on one hand, and the reasonable service life of the glass mold is ensured on the other hand, and the like.

In the prior art, when the polishing maintenance is required for the upper cavity opening and the lower cavity opening of the glass mold, a clamp which can bear and clamp the glass mold in a reasonable structure is lacked, so that an operator can only manually contact the upper cavity opening or the lower cavity opening of the glass mold with a polishing head of a polishing mechanism in a state of grasping the glass mold, and simultaneously frequently rotate the glass mold and reasonably displace the glass mold in a horizontal direction. This type of operation has the following disadvantages: firstly, because the glass mold to be maintained is manually abutted to the polishing head of the polishing mechanism in a grasping and pinching state, consistency of contact force or adherence degree between the upper cavity opening or the lower cavity opening of the mold cavity and the polishing mechanism (the polishing head of the polishing mechanism) is difficult to guarantee, so that polishing effect is seriously influenced, and maintenance quality is finally influenced; secondly, because the glass mold is relatively heavy, and because the glass mold is pinched (grasped) by both hands of the operator, the operation intensity of the operator is high, if the operator is lack of physical energy, the operator cannot perform the operation at all, and the maintenance operation has the property of rejecting the physical energy of the operator; thirdly, since the maintenance efficiency is low, there is a fear that the maintenance cost is increased and the delivery time required by the customer, that is, the user is affected (the maintenance of the glass mold is usually performed by the manufacturer by the user); fourthly, once the glass mold in the pinch state is carelessly dropped (slipped) in the maintenance process, the glass mold is damaged due to dropping to the ground, and the foot of an operator is injured (smashed) to cause serious accidents.

As is also known in the art, a tool holder is a special device for positioning a workpiece during manufacturing and/or subsequent processes and maintenance operations of a certain product to meet certain process requirements, and also generally needs to meet the requirements of no interference phenomenon during workpiece processing (including maintenance), convenient operation, relatively simple structure, and the like. Moreover, the tooling fixture has the exclusive characteristic of processing a certain workpiece or product, so that the degree of generalization is extremely low, and the tooling fixture is designed and manufactured by manufacturers of the workpiece (or the product). Based on this factor, there is no technical teaching in the patent and non-patent documents that have been published so far that is suitable for the above-described jig for repairing a glass mold, and the technical means to be described below is made under such a background.
