[0019] Compared with the related art, the injection mold for an injection molding machine provided by the utility model has the following beneficial effects:

[0020] The utility model provides an injection mold for an injection molding machine. During the production and use of the injection mold, the injection mold often needs to be transported and hoisted. In traditional operations, a lifting ring is installed on the injection mold by using a thread. During use, due to the heavy weight of the injection mold, the thread on the lifting ring is very easy to be damaged, which leads to the fall of the injection mold, low safety and great economic losses. By setting an adjustment structure, a bidirectional screw is first rotated, and the bidirectional screw drives two moving plates to move towards each other at the same time by means of the thread. In this process, the moving plate drives the limit rod to move along the support rod until the two moving plates are abutted, and then the installation frame is abutted at the installation groove, so that the moving plate and the limit rod are The positioning rod slides into the installation groove, and then the two-way screw is rotated in the opposite direction. The two-way screw drives the two movable plates to move away from each other at the same time, until the movable plate drives the limit rod to completely slide into the limit groove, so that the installation frame is fixed on the lower mold. The friction of one end of the two-way screw is increased by the anti-slip sleeve, which is convenient for the user to rotate the two-way screw to make the positioning rod slide into the positioning hole, further limit the installation frame, and facilitate the operation of the limit rod to slide into the limit groove. The two-way screw is rotated to make the two limit rods slide into the limit groove in the direction away from each other at the same time, so that the lifting ring is fixed on the lower mold, and the lower mold is lifted and transported by the lifting ring. The installation effect is stable, the safety is high, and the service life is long.

[0021] During the mold closing and injection molding process between the lower mold and the upper mold, burrs are often generated on the edge of the mother mold due to reasons such as melt leakage and insufficient mold closing pressure caused by debugging errors, which affects the injection molding quality of subsequent products. By setting an auxiliary structure, the auxiliary rod is first operated to move along the auxiliary frame to the working surface of the upper mold, and the auxiliary rod drives the scraper frame to move to the side of the upper mold close to the mother mold. During this process, one side of the upper mold squeezes the inclined surface of the scraper on the scraper frame, so that the scraper frame is close to the auxiliary rod, and the spring is in a compressed state. The spring always gives the scraper frame an elastic force close to the upper mold, and then continues to move the auxiliary rod along the auxiliary frame, and uses the scraper on the scraper frame to scratch the surface of the mother mold. The scraper frame is further limited by the sliding rod to make the scraper frame more stable during movement. The auxiliary rod is driven to move by operating the handle bar, which is convenient for the user to move the auxiliary rod along the auxiliary frame, so that the auxiliary rod is moved along the auxiliary frame, and the auxiliary rod drives the scraper frame to sweep the working surface of the upper mold, and the scraper on the scraper frame is used to clean the burrs on the edge of the mother mold. The operation is simple and convenient, and the product quality is improved. BRIEF DESCRIPTION OF THE DRAWINGS
