Embodiment Construction

[0010] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0011] Such as Figure 1 to Figure 2 The shown hot runner system for injection molding includes: a plate surface 1, which is made of aluminum alloy. One side of the board surface 1 is provided with nut slots 2, and the other side is provided with through holes 3. There are two nut slots 2, each nut slot 2 communicates with three through holes 3, and the through holes 3 communicate with the nut slots 2.

[0012] The nut 4 is placed in the nut groove 2, which includes two independent threads, the thread 6 is used to connect with the bolt so that the nut 4 is fixed on the plate surface 1, and the thread 5 is used for fixed connection with other feed ports. The width of the ...

Abstract

The invention discloses a hot runner switching plate including a plated surface. One side of the plated surface is provided with nut grooves, the other side of the plated surface is provided with through holes, and the through holes are communicated with the nut grooves; nuts are arranged in the nut grooves and each comprise two sections of independent screw threads, and the width of the nut grooves is close to an opposite-side distance of each of the nuts so that the nuts cannot rotate in the nut grooves; bolts successively each pass through the through hole and the nut groove, and then are each fixedly connected with the nut. The hot runner switching plate adopts connection of the nuts and the bolts to replace threaded holes on the plated surface in the prior art, so that the processing cost is reduced, and even if a part of installation holes are damaged during a using process, the nuts and the bolts are only required to be replaced, and thus the maintenance cost is obviously reduced.

Description

technical field [0001] The invention relates to the technical field of injection molding, in particular to an adapter plate for a hot runner. Background technique [0002] In the injection molding machine, an adapter plate is needed to control the switching of oil, raw materials, and water. The adapter plate includes several adapter holes, which are respectively connected to the feed pipes for transferring different materials. The existing adapter plate is generally made of steel, and the adapter hole is a screw hole tapped on the steel plate. The larger the thread, the thicker and heavier the adapter plate must be. Once one of the threads is damaged, the entire adapter plate will be damaged. The connecting board needs to be replaced, and the maintenance cost is relatively high. Contents of the invention [0003] The technical problem to be solved by the present invention is how to solve the problem of high maintenance cost once the thread of the adapter hole is damaged i...
