Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Example 1

Referring to fig. 1 and 2, the auxiliary device for sleeving the rubber ring in this embodiment includes a core 1 for being sleeved by the rubber ring and guiding the rubber ring to a mold to be sleeved, wherein the core 1 is an integrated structure having an infinite cross section and formed by two parallel and vertically arranged cylindrical bodies with a tapered top end and a cylindrical bottom end;

through the arrangement, the rubber ring can be sleeved on the core from top to bottom from the tip of the upper part of the core 1, and the rubber ring sleeved on the rubber ring can be kept stable due to the cylindrical arrangement of the lower part of the rubber ring;

in the embodiment, in order to avoid the rubber ring sleeved on the core 1 from separating from the core 1 from bottom to top, two sides of the joint of the two cylindrical bodies are respectively provided with a convex block 2, the two convex blocks 2 are arranged symmetrically relative to the center of the core 1, and the maximum distance between the outer edges of the two convex blocks in the horizontal direction is not more than the diameter of the cylindrical bodies;

after the rubber ring is sleeved on the core 1, due to the arrangement of the convex blocks 2, even if the rubber ring is upwards contracted at the conical part of the core, the two convex blocks 2 can effectively block the contraction of the rubber ring, so that the purpose of preventing the rubber ring from being separated is realized;

in the embodiment, in order to prevent the rubber ring from separating from the core 1 from top to bottom, the center of the bottom of the core 1 is rotatably connected with a boss 8 which can be embedded at the top of the quilt cover mold so as to connect the core 1 with the quilt cover mold through a rotating shaft 7, the width of the boss 8 is less than the narrowest distance of the connection part of the two columnar bodies, and the length of the boss 8 is greater than the diameter of the columnar body and less than 2 times of the diameter of the columnar body;

through the arrangement, when the two ends of the boss 8 rotate through the rotating shaft 7 and contract to the inner side of the bottom of the core 1, the rubber ring can be separated from the core 1 from top to bottom, so that the rubber ring can slide onto a quilt cover mold; when the two ends of the boss 8 rotate to the outer side of the bottom of the core 1 through the rotating shaft, the two ends of the boss can support the rubber ring on the boss, and the rubber ring can be effectively prevented from being separated from the core 1 from top to bottom.

In this embodiment, in order to facilitate the propulsion of the rubber ring to slide to the quilt cover mold, a gland 3 is further arranged, the distance between the vertical wall at the bottom of the inner cavity of the gland 3 and the vertical wall of the cylindrical part at the bottom of the core 1 is not more than 1mm, a base 5 is further arranged, a plurality of through holes 6 used for clamping and guiding the quilt cover mold are formed in the base 5, and the cross sectional area of the bottom end of the core 1 is the same as that of the top end of the quilt cover mold.

Through the arrangement, the gland 3 can effectively drive the rubber ring sleeved on the core 1 to move downwards, so that the rubber ring slides to the quilt cover die.

By arranging the base 5 and the through hole 6, the sleeved die can be effectively guided and positioned.

By setting the cross sectional area of the bottom end of the core 1 to be the same as that of the top end of the quilt cover mold, the sliding difficulty of the rubber ring can be effectively reduced, and the rubber ring can conveniently slide to the quilt cover mold.

Example 2

Referring to fig. 1 and 2, in the present embodiment, the core 1 is specifically composed of a cylindrical body with a tapered top end and a cylindrical bottom end (i.e. a cylindrical body, which is equivalent to the core 1 in embodiment 1 being divided into two parts, only one half in the present embodiment), the core 1 is provided with a protruding block 2 for catching the rubber ring to prevent it from sliding upwards on the vertical wall of the tapered part, the maximum vertical distance from the outer edge of the convex block 2 to the axis of the core 1 is not more than the radius of the cylindrical part at the bottom of the core 1, a gland 3 is also arranged, the bottom of the gland 3 is provided with a groove 4 capable of accommodating the whole core 1, and the distance between the vertical wall of the bottom of the inner cavity of the gland 3 and the vertical wall of the cylindrical part at the bottom of the core 1 is not more than 1mm, the base 5 is also arranged, a plurality of through holes 6 used for clamping and guiding the quilt cover mould are arranged on the base 5, and the cross sectional area of the bottom end of the core 1 is the same as that of the top end of the quilt cover mould.

The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
