Embodiment 1

[0040] combine figure 1 , figure 2 , image 3 , Figure 4 and Figure 5 , a method of installing an insert into an injection mold according to this embodiment, the steps are as follows:

[0041] Step 1: Install the insert in the insert groove on the tooling fixture 1; when installing, the four inserts and the four insert grooves must be in one-to-one correspondence before the insert can be installed in the insert groove;

[0042] Step 2: Hold the handle 105 with your fingers, pick up the jig 1, and align the positioning block 109 on the jig 1 with the corresponding position on the mold;

[0043] Step 3: Following step 2, push the tray 101 by hand, so that the tray 101 pushes the guide bar 102 to drive the guide block 107 to push the thimble 108 forward, and then drives the thimble 108 to push the insert forward. When the top of the thimble 108 passes through the insert When inserting the part groove, the insert is pushed into the cavity of the mold to complete the action o...

Embodiment 2

[0056] An insert injection molding device for plastic plug molding in this embodiment has the same basic structure as that in Embodiment 1, except that the number of inserts, insert grooves and thimbles 108 in this embodiment are all six.

Embodiment 3

[0058] An insert injection molding device for plastic plug molding in this embodiment has the same basic structure as that in Embodiment 1, except that the number of inserts, insert grooves and thimbles 108 in this embodiment is eight.

Abstract

The invention discloses a method for installing inserts in an injection mold and belongs to the field of plastic production equipment. The method includes the following steps that firstly, the inserts are installed in an insert groove in a tool clamp; secondly, a handle is fastened through a finger, the tool clamp is taken up, and a locating block on the tool clamp is aligned with the corresponding position on the mold; and thirdly, a tray is pushed by a hand, so that the tray pushes a guide rod to drive a guide block to push ejector pins to move forwards, the ejector pins are driven to push the inserts to move forwards, and the inserts are pushed in a mold cavity of the mold. The method has the main purposes that the multiple inserts can be installed in the mold at a time, meanwhile, the installation efficiency for installing the inserts in the tool clamp is improved, the overall installation time is saved, the labor intensity is relieved, the production efficiency is improved, meanwhile, the phenomenon that the inserts are forgotten to be installed or mistakenly installed is avoided, the product quality is guaranteed, and the production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of plastic production equipment, and more particularly, to a method for installing an insert into an injection mold. Background technique [0002] There are some plastic plugs in the automobile fuel supply system, due to the requirements of insulation, conductivity and sealing performance, the design is often complicated. The inserts of these plugs need to be installed in the mold during injection molding, and the inserts are wrapped after injection molding into products In the plastic, there are often 4-8 inserts on these plugs, and every 2 are the same. For example, among the 8 inserts, there are actually 4 inserts, each insert 2 indivual. [0003] In the prior art, when producing these plastic plugs by injection molding, the operator installs the inserts one by one into the injection mold, which obviously increases the labor intensity and reduces the production efficiency, especially when the product nee...
