Further, heating unit is additionally provided between the screw rod and hot flow path, and the temperature of heating unit is controllable
Temperature.
Further, mold runner is additionally provided with the mould, the hot flow path is directly connected to mold runner.
Further, the temperature of the boiling case is constant temperature, and temperature is controllable temperature.
Further, dry and resin up to standard is equipped with the material cup.
Due to the utilization of above-mentioned technical proposal, this equipment can control injection to produce to the utility model compared with prior art
The destabilizing factor of process, makes 100% product meet that 10KN stretchings require；The quality of product is improved, and improves production effect
Rate, reaches effective control to cracking product, it is ensured that all products all meet the needs of client.

Embodiment
It is in order to make those skilled in the art better understand the technical solutions in the application, real below in conjunction with the application
The attached drawing in example is applied, the technical solution in the embodiment of the present application is clearly and completely described, it is clear that described implementation
Example is merely a part but not all of the embodiments of the present application.It is common based on the embodiment in the application, this area
Technical staff's all other embodiments obtained without making creative work, should all belong to the application protection
Scope：
A kind of former of prevention position limit arm cracking as shown in Figure 1, including injection molding machine 1, steel core processing unit and
Boiling case 3；The steel core processing unit and boiling case 3 is connected to the same side of injection molding machine 1, and steel core processing unit is positioned at note
The front side of molding machine platform 1, boiling case 3 are located at the rear side of injection molding machine 1；The steel core processing unit includes steel core feeding device 21
With steel core heating unit 22, steel core heating unit 22 is connected to the side of steel core feeding device 21；Set on the injection molding machine 1
There are material cup 4, screw rod 5, hot flow path 6 and mould 7；The material cup 4 is arranged at the front position on injection molding machine 1, described
Screw rod 5 is connected to the side of material cup 4；The hot flow path 6 and the mould 7 are placed in the opposite side of screw rod 5, hot flow path 6
