Description

Table tennis inverse rubber blind hole die

Technical Field

The utility model belongs to a mould, in particular to table tennis inverse rubber blind hole mould.

Background

The surface covering of the table tennis bat is made of rubber and is divided into an upper layer, a middle layer and a lower layer. The upper layer is rubber, the middle layer is adhesive, and the lower layer is sponge. The ping-pong sponge is a sheet-shaped foamed rubber product with the thickness of 0.5-2 mm; the rubber is a sheet solid rubber product with the thickness not more than 2mm, one surface is a plane, the other surface is columnar particles which are uniformly arranged at intervals, the particles are required to be arranged along three parallel lines which are 60 degrees mutually, and the rubber is divided into a reverse rubber and a forward rubber according to the inward or outward of one surface of the particles. The table tennis rubber is a rubber product manufactured by adopting a mould pressing vulcanization process.

The most traditional table tennis inverse rubber mold is designed with the eye mold and the bottom mold separated, has the advantages of low processing difficulty and high use flexibility, and is the most widely used table tennis inverse rubber mold at present. However, it has the following disadvantages:

1. the eye mould and the bottom mould are separately designed, the mould has poor dimensional stability and is easy to deform and wear, the prepared rubber has poor dimensional stability and precision, and the thickness tolerance is more than 0.2 mm;

2. the eye mold and the bottom mold are separately designed, so that vulcanized rubber easily overflows from the middle of the eye mold and the bottom mold to generate burrs, the processing precision of a product is influenced, a manual mold rubbing process needs to be matched, the labor intensity is high, the automation degree is low, and the production environment is polluted by flying of rubber scraps;

3. the whole thickness of mould is thinner, and temperature stability is poor, does not have the locating pin design, does not have the design of tearing the limit muscle fast, is unfavorable for cooperating the automated manufacturing of automatic vulcanization equipment realization.

According to patent CN2556004Y 'Ping-Pong rubber surface blind hole two-opening die', the design of earlier blind hole Ping-Pong rubber die realizes that the eye die and the bottom die are combined into a whole, and has the advantages of high processing precision, no rough edge, high die rigidity, and difficult deformation and abrasion. However, it has the following disadvantages:

1. the single-connection blind hole die is used for forming a piece of table tennis rubber through one-step vulcanization, so that the production efficiency is low;

2. the design of no torn edge ribs is adopted, the edge is removed, and the cutting is carried out by scissors, so that the labor efficiency is lower;

3. the mold is manually opened and closed, and automatic production cannot be realized.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome foretell defect, provide a table tennis inverse rubber blind hole mould, can cooperate plug-type automatic curing press to realize high accuracy, automation, the high efficiency processing of table tennis inverse rubber.

The utility model aims at realizing through the following technical scheme: the utility model provides a table tennis inverse rubber blind hole mould which characterized in that: the blind hole die comprises a blind hole die, a face die, positioning pin holes and mounting holes, wherein the positioning pin holes are formed in a relative frame of the blind hole die, the mounting holes are formed in two sides of each positioning pin hole, shallow grooves are formed in the inner side of the frame, a plurality of blind holes are arranged in the shallow grooves, tearing ribs are arranged along four sides of the shallow grooves, a trademark area is arranged on the inner surface, opposite to the blind hole die, of the face die, trademark patterns are arranged in a quadruple mode and correspond to the quadruple mode in the shallow grooves, and the positioning pin holes and the mounting holes are formed in the face die and correspond to the positioning pin holes and the mounting holes in the blind hole die in a one-to-one mode respectively.

Still be equipped with two mutually perpendicular's the limit muscle of tearing in the shallow recess, equally divide shallow recess into the quadruple and arrange.

The utility model has the advantages and beneficial effects that:

1. the surface die and the blind hole die are provided with positioning pin holes and mounting holes, and are fixed on an automatic plate vulcanizing machine through the mounting holes, so that the full-automatic die opening and closing is realized, the push-pull type automatic plate vulcanizing machine is matched to realize the high-precision, automatic and high-efficiency processing of the table tennis inverse rubber, and the labor intensity is greatly reduced.

2. The blind hole area adopts the quadruple design, greatly improves production efficiency.

3. The edge ribs are not cut and torn, no adhesive scrap is generated in the whole production process, and the production is environment-friendly and clean.

4. The quadruple design of the blind hole area is matched with a high-precision, automatic and high-efficiency ping-pong reverse rubber processing technology, and the thickness tolerance of the rubber can be reduced to 0.03-0.07 mm.
