Background

The modern automation industry is rapidly developed, the precision requirement on various small parts is also improved, and the rubber coating material is taken as a small airtight part to be paid more and more attention by automation enterprises, but the structural part of the existing rubber coating part is difficult to rubber coat, the surface of the part is easy to generate a 'gas trapping' phenomenon, the adhesive force of the rubber coating part is poor, and the rubber coating part and a body are generally layered and fall off; in addition, the forming process is unstable, the requirement on the self-checking proficiency of workers is extremely high, the labor cost is increased, and if the adhesive force is poor, the product is scrapped, so that the quality complaint of customers is caused.

SUMMERY OF THE UTILITY MODEL

The utility model discloses the purpose: in order to improve the structure of a rubber coating material, improve the product quality and the production efficiency and reduce the self-checking strength and the manufacturing cost of operating personnel, the rubber coating material with an improved structure is designed to improve the product quality, improve the production efficiency, reduce the production cost and reduce the fraction defective of parts.

The technical scheme adopted for solving the problems is as follows:

the utility model provides an improvement structure's rubber coating material, includes flexible glue and material body, the flexible glue is cyclic annular to be in through the parcel of moulding plastics the plastic material of material body upper surface, the material body is cyclic annular, and a plurality of reverse counter bores have evenly been seted up to the upper end ring surface, and counter bore terminal surface surveys in promptly for when moulding plastics, flexible glue extrusion flow in the counter bore and shaping, forms the dead injection structure of lock, and the cooling at last, the die sinking takes out the rubber coating material part that the parcel is good.

According to the design scheme of the rubber coating material with an improved structure, the injection mold for designing, producing and preparing the rubber coating material is provided, and comprises an upper mold core, a lower mold core, an upper pressing plate, a lower pressing plate, a guide rod, an injection molding end plate and a base, wherein the material body is pre-placed in a mold cavity formed between the upper mold core and the lower mold core, a hard silica gel ring is sleeved on the periphery of the middle convex end face of the lower mold core and used for backflushing the injection molding pressure of soft rubber,

when injection molding is carried out, the hard silica gel ring does not resist injection molding pressure, namely, the soft rubber injection molding material can be fully filled in the mold cavity, all the reversed counter bores are filled under adjustable injection molding pressure until the lower boss is fully filled with the soft rubber injection molding material, the soft rubber injection molding material is shaped after cooling, and the mold is rapidly and efficiently demolded under the reverse thrust of the extruded hard silica gel.

Furthermore, the hole site of counter sink is located the centre circle of the material body upper end ring surface to reverse counter sink lower extreme link up.

Further, the small hole diameter range of the reversed counter sink is 0.6-1.5 mm.

The utility model has the advantages that: its research scheme of this rubber coating material of improvement structure obtains more extensive application, compares with the material that does not add the hole site, does not receive influence such as machine change and forming process technology change, with the structure improvement research scheme of strengthening the connection of moulding plastics through trompil an organic whole between flexible glue and the material, not only makes the defective products rate end, and the quality guarantee is stable, can satisfy the needs of most similar product occasions moreover.
