Injection molding is a processing method used in mass production of certain parts with complex shapes. The injection mold consists of two parts: a movable mold and a fixed mold. The movable mold is installed on the movable template of the injection molding machine, and the fixed mold is installed on the fixed template of the injection molding machine. During injection molding, the movable mold and the fixed mold are closed to form a pouring system and a cavity. The hot-melt plastic is injected into the cavity through the pouring system, and the desired product is formed after cooling and molding. When the mold is opened, the movable mold and the fixed mold are separated to remove the plastic product.

[0003] However, after the parts are formed, they are manually removed. At this time, the model may be damaged due to uneven force on the model. For this reason, we design molds for parts production and processing, which can stably push out the molded parts. Utility Model Content

The multiple spline sleeves 11 simultaneously drive the spline shafts 22 and the push rods 8 to rotate synchronously.

[0027] A bearing plate 13 is fixedly connected inside the lower frame plate 4 , and a plurality of spline sleeves 11 are all connected thereto in a limited rotational manner, so that the plurality of spline sleeves 11 can rotate stably.

[0028] The motor 14 is fixedly mounted on the bearing plate 13, and the power output end of the motor 14 is connected to a rotating column 15, and the other end of the rotating column 15 is rotatably connected to the lower frame plate 4. The outer wall of the rotating column 15 is fixedly connected to a first gear 16, and the outer wall of the outermost spline sleeve 11 is fixedly connected to a second gear 18, and the second gear 18 and the first gear 16 are meshed with each other.

[0029] The inner wall of the lower frame plate 4 is connected to a sliding rod 10 in an upper and lower limited sliding manner through a second limited sliding groove 9, and a plurality of spline shafts 22 are connected to the sliding rod 10 in a limited rotation manner.

[0030] A plurality of first electric telescopic rods 12 are also fixedly installed in the lower frame plate 4, and the telescopic ends of the plurality of first electric telescopic rods 12 are connected to the sliding rod 10, so that the sliding rod 10 can move up and down stably. The first electric telescopic rod 12 can be any one of a cylinder, a hydraulic rod, and an electric telescopic rod. The wires and pipes of the first electric telescopic rod 12 and the bearing plate 13 pass through the lower frame plate 4 and are connected to an external power source or compressed gas.

[0031] The outer wall of the lower frame plate 4 is fixedly connected to the upper mold 1 through the connecting plate 19, the top of the upper mold 1 is limitedly slidably connected to a plurality of guide pillars 6, the bottom of the plurality of guide pillars 6 is fixedly connected to the upper mold 1, and the upper mold 1 cooperates with the lower mold 3 to perform die-forming of accessories.
