Description

Technical Field

[0001] The utility model relates to the technical field of mold production, and specifically relates to a fastening structure for a mold guide sleeve. Background Technique

[0002] A mold guide sleeve, also known as (mold guide sleeve, high-strength brass bearing), is a high-performance solid lubrication product in which graphite or MoS2 solid lubricant is embedded in the matrix of high-strength brass. It breaks through the limitation of general bearings relying on oil film lubrication. During use, through frictional heat, the solid lubricant rubs against the shaft to form excellent lubrication conditions with both oil and powder coexisting, which not only protects the shaft from wear but also makes the solid lubrication characteristics permanent.

[0003] A fastening structure for a mold guide sleeve described in the patent publication number CN217121496 can quickly fasten and lock the position of the guide sleeve, so that during the use of the mold, the guide sleeve will not fall off. It can not only ensure the normal operation of the guide sleeve but also effectively prevent the guide sleeve from being damaged due to accidental falling.

[0004] However, in the prior art, most of the fastening structures are welded to the male template, and the lengths for fastening the mold guide sleeve are not exactly the same due to the needs of mold production. If the mold guide sleeve needs to be replaced, it is inconvenient. Since the fastening structure is fixedly connected to the male template, it is necessary to open a new set of molds and set a mold guide sleeve with a suitable length to make the length of the mold guide sleeve meet the requirements, which will greatly increase the mold opening cost.

[0005] Therefore, the technical personnel in the field provide a fastening structure for a mold guide sleeve to solve the problems raised in the above background technique. Content of the Utility Model

[0006] The purpose of the utility model is to provide a fastening structure for a mold guide sleeve to solve the deficiencies raised in the above background technique.

[0007] To achieve the above-mentioned utility model purpose, the utility model adopts the following technical scheme:

[0008] The utility model provides a fastening structure for a mold guide sleeve, which includes a male template. Fixed cavities are opened at the four corners of the surface of the male template. A fastening cylinder is movably arranged in the middle of the interior of the fixed cavity. The bottom of the fastening cylinder is in contact with the inner bottom wall of the fixed cavity. A threaded hole is opened at the axial center of the top end of the fastening cylinder. The fastening cylinder is threadedly connected with a threaded head through the threaded hole. The top end of the threaded head is fixedly provided with a guide sleeve body. The guide sleeve body is arranged above the fastening cylinder. A plurality of groups of clamping blocks are equidistantly arranged on the bottom surface of the bottom end of the fastening cylinder. A plurality of groups of clamping grooves that are snap-fitted with the clamping blocks are equidistantly arranged on the bottom wall of the fixed cavity.

[0009] Preferably, a guiding mechanism is provided on the inner wall of the fixed cavity. The fixed cavity is connected with a positioning spring through the guiding mechanism. The positioning spring is elastically connected with a positioning plate. A plurality of positioning columns are equidistantly arranged on the inner side wall of the positioning plate. Positioning holes adapted to the positioning columns are equidistantly formed on the outer middle surface of the fastening cylinder.

[0010] Preferably, the guiding mechanism includes a guiding groove provided on the inner wall of the fixed cavity. A guiding rod is fixedly arranged inside the guiding groove. The guiding rod is slidably connected with a guiding block. The guiding block is fixedly connected with the positioning spring.

[0011] Preferably, a plurality of groups of assembly plates are annularly arranged on the outer middle surface of the fastening cylinder. The bottom end of the assembly plate abuts against the surface of the male template. An assembly hole is formed inside the assembly plate.

[0012] Preferably, a wear-resistant sheet is arranged on the outer side wall of the top of the fastening cylinder. The wear-resistant sheet is made of polyurethane material.

[0013] Preferably, a dust-proof washer is arranged on the outer side of the top of the fastening cylinder. The lower surface of the dust-proof washer fits with the top surface of the fastening cylinder. An installation hole adapted to the guide sleeve body is formed in the middle of the dust-proof washer.

[0014] Compared with the prior art, the above one or more technical solutions have the following beneficial effects:

[0015] The utility model provides a fastening structure for a mold guide sleeve. On the basis of a set of molds, the fastening structure of the mold guide sleeve and the mold guide sleeve are set as a threaded detachable type, and the fastening structure and the male template are also set as a quick-release type. The mold guide sleeve on the fastening structure can be replaced as needed (replaced with a mold guide sleeve of a suitable length), and then the fastening structure together with the mold guide sleeve itself is installed on the male template for work. This not only facilitates the quick replacement of the mold guide sleeve and the quick installation of the fastening structure, but also can avoid the additional increase of the mold opening cost, and has certain economic benefits.
