Technical Field

The invention relates to the technical field of injection mold manufacturing, in particular to a mold matching auxiliary device of an injection mold.

Background

In the production process of the injection mold, after machining of a movable mold and a fixed mold (or a male mold and a female mold) is completed, mold matching needs to be carried out on parting surfaces of the movable mold and the fixed mold; in the process of matching the injection mold, red lead is coated on the parting surfaces of the movable mold and the fixed mold, then the movable mold and the fixed mold are combined together, one of the movable mold and the fixed mold is beaten by a copper rod, so that the movable mold and the fixed mold are further combined together, whether the contact between the parting surfaces is good or not is confirmed by coloring the red lead, if no red lead exists on the parting surfaces, a problem is marked, and the movable mold and the fixed mold need to be polished. In some small mold production plants, because of limited capital, the molds are beaten by manually swinging the copper rods, so that the working intensity of workers is high and the danger coefficient is high.

Disclosure of Invention

The copper bar hammering mechanism further comprises a loading block fixedly connected with the copper bar, the loading block is sleeved in the sleeve, a step cylinder body with a large upper part and a small lower part is formed at the upper end of the loading block, a pair of clamping jaws which are arranged in bilateral symmetry are arranged on the outer side of the step cylinder body, the step surface of the step cylinder body is pressed on a transverse plate at the lower ends of the two clamping jaws, a pressure spring is fixed between the inner side walls of the inclined plates at the upper ends of the two clamping jaws, the middle parts of the two clamping jaws are respectively hinged on two hinged shafts of the lifting frame, the lifting frame is provided with a connecting rod which protrudes backwards, the connecting rod is inserted and sleeved in a rectangular groove on the side wall of the sleeve, the connecting rod penetrates; an inclined plane with a low outside and a high inside is formed on the lower side wall of the transverse plate at the lower end of the clamping jaw;

a cylinder cover is fixed at the top end of the sleeve, a square taper hole with a large lower side and a small upper side and an opening lower side is formed in the middle of the cylinder cover, and the left side wall and the right side wall of the square taper hole are respectively matched with the outer side walls of the inclined plates of the two clamping jaws;

the cylinder is connected with a switch for controlling the extension or contraction of a piston rod of the cylinder, and the switch is arranged on the movable frame.

The movable frame comprises two bending support legs which are arranged in bilateral symmetry, the position adjusting mechanism further comprises two wheel seats which are respectively fixed at the lower ends of the two bending support legs, and two universal wheels which are arranged in the front and back direction are fixed on each wheel seat.

And a plurality of weight reduction grooves are formed in the outer wall of the sleeve.

The negative weight block is a lead block.

One of the bending support legs is fixed with a handle.

An inner flanging is formed on the inner wall of the lower end of the sleeve, and the diameter of the inner flanging is smaller than that of the negative weight block.

And an arc-shaped round table is formed at the lower end of the copper rod.

The invention has the following outstanding effects: compared with the prior art, its bar copper can beat injection mold automatically, and conveniently adjusts the position of beating, can effectively reduce workman's working strength and danger coefficient.
