Description

Technical Field

[0001] The utility model relates to the technical field of linear rails for injection molding machines, in particular to a linear rail mechanism for injection molding machines. Background Art

[0002] Injection molding machines, also known as injection molding machines or injection machines, are widely used equipment in the industrial field, mainly used to produce plastic products of various shapes and sizes. Its working principle is similar to that of a syringe for injections, which injects thermoplastic or thermosetting plastics into a mold and obtains a finished product after cooling and solidification. The importance of injection molding machines in modern manufacturing is self-evident, and they are widely used in many industries such as automobiles, home appliances, medical care, and packaging.

[0003] The competition in the injection molding machine industry is very fierce now. In order to meet the delivery date of customers, the production time must be considered from the very beginning of the design stage. At present, in the design process, a new part called the linear guide support is often made for the clause of lengthening the injection stroke. However, when the delivery date is urgent and it is necessary to ensure on-time delivery, it is a big challenge for the design department. When designing on a newly developed model, due to the complex on-site conditions, the length of the injection stroke often needs to be adjusted when it is put into production. In order to cope with emergency adjustments, the temporary method is to let the tail of the linear guide protrude a certain distance to ensure that the injection can be withdrawn to the bottom without falling out of the linear guide, and then design and manufacture a new linear guide support.

[0004] However, the manufacturing cycle of the newly designed linear rail support for subsequent component factories often takes about one month, which will seriously deviate from the customer's delivery requirements. Although protruding the linear rail for a certain distance has no effect on assembly, long-term operation will affect the life of the linear rail because the protruding linear rail will be at risk of deformation when subjected to compressive stress, thus affecting subsequent use. In view of this, the present application proposes a linear rail mechanism for an injection molding machine. Utility Model Content

[0025] The linear rail support assembly 4 includes a latch 41 slidably mounted inside the plug slot 101, an extended support base 42 is fixedly mounted on one side of the latch 41, a T-shaped slide 421 is provided on the top of the extended support base 42, and a T-shaped nut slider 5 is slidably mounted inside the T-shaped slide 421. The installation position of the extended linear rail 6 is adapted by adjusting the position of the T-shaped nut slider 5 in the T-shaped slide 421.

[0026] Secondly, the top of the extended support base 42 is flush with the top of the linear rail support 1, and one side of the extended support base 42 is in contact with one side of the linear rail support 1. The extended support base 42 is installed to one side of the linear rail support 1 through the latch 41, and the extended support base 42 is supported by the latch 41, and the extended linear rail 6 is supported to prevent the extended linear rail 6 from being deformed.

[0027] At the same time, a first screw hole 51 is provided at the top of the T-nut slider 5, and a second screw hole 52 is provided at the top of the T-nut slider 5. The first screw holes 51 and the second screw holes 52 of different specifications are adapted to the installation of various types of extension rails 6.

[0028] Among them, a countersunk hole 61 is opened at the top of the extension rail 6, and a hexagon socket bolt 62 is penetrated inside the countersunk hole 61, and the hexagon socket bolt 62 is adapted to the first screw hole 51 or the second screw hole 52.
