Description

Technical Field

[0001] The utility model belongs to the technical field of molds and relates to a sliding limit block structure of a luggage box mold. Background Art

[0002] A suitcase, also known as a travel case or trolley case, is a box that is carried when traveling and is used to store items. It is one type of luggage. Suitcases are usually used to store clothes, personal care products and souvenirs needed for travel. Suitcases can also be divided into hard-shell suitcases and soft-shell suitcases based on the outer shell. Hard-shell suitcases are more resistant to falling and are suitable for luggage that requires more protection. Soft-shell suitcases are usually lighter than hard-shell suitcases and are made of more flexible materials.

[0003] When manufacturing suitcases, they are directly injection molded through the injection mold. However, when the existing injection mold parts are demoulded, the inclined ejector structure used does not have corresponding limit blocks to limit the slider when it slides, and the slider is easy to fall off. At the same time, the guide grooves on the traditional inclined push rods are directly opened on the inclined push rods. When the guide grooves are worn, the entire inclined push rod needs to be replaced, which is very costly. Summary of the Invention

[0005] The purpose of this utility model can be achieved through the following technical solutions:

[0006] The sliding limit block structure of the suitcase mold includes a support seat, a slider, a limit block body, a positioning rod and a push rod. A slide groove is provided inside the support seat, and the slider is slidably connected inside the slide groove. The limit block body is provided at the top position of the slide groove. The surface of the slider is movably installed with a push rod through a pin shaft. A guide frame is installed outside the push rod, and a guide groove is provided at the top of the guide frame.

[0007] In the above-mentioned sliding limit block structure of the luggage case mold, side grooves are formed at the top and bottom ends of the push rod, and the guide frame is mounted on the side grooves.

[0008] In the above-mentioned sliding limit block structure of the luggage case mold, two limit grooves are provided inside the side groove, and two limit plates are provided inside the guide frame, and the limit plates are placed inside the limit grooves.

[0009] In the above-mentioned sliding limit block structure of the luggage case mold, a locking bolt is connected to the front end of the limit plate, and the locking bolt passes through the push rod and is threadedly sleeved with a locking nut on the surface of the push rod.

[0010] In the above-mentioned sliding limit block structure of the luggage case mold, a positioning hole is opened inside the limit block body, a positioning rod is provided on the top of the support seat, and one end of the positioning rod is inserted into the positioning hole.

[0011] Compared with the prior art, the advantages of the sliding limit block structure of the luggage case mold of the present invention are:

[0012] The present application sets a limit block body at the top of the slide groove, which can effectively avoid the risk of the slider falling off naturally through the limit block, protect the slider, and the limit block can be fixed at the end of the slide groove by a positioning rod, and the fixation is simple and efficient. The push rod of the present application is provided with a detachable guide frame on the outside, and when the guide groove inside the guide frame is worn, the guide frame can be directly replaced. The guide frame is installed by locking bolts and limit plates, and the replacement is simple and efficient. In this way, there is no need to replace the entire push rod, and the use cost is greatly reduced. BRIEF DESCRIPTION OF THE DRAWINGS
