Description

Technical Field

[0001] The utility model relates to the technical field of injection molds, in particular to a high-precision positioning intelligent speed-controlled injection mold. Background Art

[0002] An injection mold is a key tool used to form plastic products during the injection molding process. Plastic particles are heated and plasticized in the barrel of the injection molding machine to form a melt. The screw or plunger of the injection molding machine pushes the melt through the main channel, branch channel and gate, and into the space formed by the mold cavity and core. With the development of technology, injection molds are equipped with throttle valves and other devices during injection molding to control the injection flow rate of the injection mold.

[0003] In daily work, it is found that in the process of closing the injection mold, the mold is mainly driven by the telescopic cylinder to move, and the mold is displaced along the guide column to complete the closing operation. Since there is sliding contact between the guide column and the mold, wear is very likely to occur between the two under long-term use and frequent closing operations. This wear will gradually change the matching accuracy between the guide column and the mold, resulting in a decrease in the accuracy of the guide positioning, which will affect the precision of the closing and the quality of the injection molded product. Utility Model Content

Through the above-mentioned components, when in use, the moving part and the ball body can be controlled to move by adjusting the component, so that the ball body is closely fitted with the surface of the guide frame. When the ball body moves in the guide frame, friction can be reduced, thereby achieving precise positioning and allowing mold one and mold two to be accurately molded.

[0007] Preferably, a hexagonal inner groove is provided on the surface of the knob, and a tool can be inserted into the hexagonal inner groove through the above-mentioned component to control the rotation of the adjusting screw.

[0008] Preferably, the inner wall of the fixing frame is rotatably connected to four rollers, and the four rollers are arranged in pairs on both sides of the fixing frame. Through the above components, when the fixing frame cooperates with the ball body to move on the guide frame, the rollers can move in fit with the side of the guide frame, thereby reducing friction.

[0010] Preferably, the air supply pipe includes a main pipe installed on the machine base, and two air inlet pipes are fixedly connected to the surface of the main pipe. One end of the two air inlet pipes is respectively connected to the blowing heads. Through the above components, the main pipe can be connected to the air supply equipment, and then the two blowing heads can be supplied with air through the two air inlet pipes.

[0011] Compared with the prior art, the advantages and positive effects of the present invention are:

[0012] 1. In the present invention, by setting a stabilizing device, the fixed frame, the moving part, the ball body, and the adjusting assembly cooperate to provide a high-precision guide for the movement of the mold.
