Description

Technical Field

[0001] The utility model relates to the technical field of injection molding product production, in particular to a blanking device for injection molding products after molding. Background Art

[0002] Injection molded products, also known as injection molded products, are products obtained by heating and plasticizing plastics in an injection molding machine, then injecting them into the cavity of a molding mold, and then demolding them after cooling and solidification of the melt. Injection molded products are widely used in many fields and have various characteristics and application scenarios.

[0003] However, existing injection molded products have the following problems after molding: after molding, the product is generally clamped and moved by a robotic arm, and then moved to the next operating workshop via a conveyor belt. During the clamping and moving process, the newly molded injection molded product has a certain degree of softness due to the high temperature and may fall off the robotic arm, damaging the product and posing a safety hazard. Utility Model Content

[0004] The purpose of the utility model is to solve the problem in the prior art that after the product is formed, it is generally clamped and moved by a mechanical arm, and then moved to the next operation workshop by a conveyor belt. During the clamping and moving process, the newly formed injection molded product has a certain degree of softness due to the high temperature and may fall off the mechanical arm, damaging the product and posing a safety hazard. A device for unloading injection molded products after molding is proposed.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A post-molding unloading device for injection molded products, comprising a bottom plate, a top plate, a mold, an ejector plate and an electric telescopic rod, wherein the top four corners of the bottom plate are fixedly connected to support rods, and the top ends of the four support rods are respectively fixedly connected to the bottom four corners of the same top plate, a hole adapted to the mold is opened at the center of the top plate, the mold is fixedly arranged in the hole, an ejector plate is slidably arranged on the inner wall of the mold, the bottom of the ejector plate is fixedly connected to a No. 1 U-shaped frame, the bottom of the No. 1 U-shaped frame is fixedly connected to the telescopic end of the electric telescopic rod, both sides of the bottom of the mold are fixedly connected to the same No. 2 U-shaped frame, the fixed end of the electric telescopic rod is fixedly arranged on the No. 2 U-shaped frame, and the four corners of the bottom of the bottom plate are fixedly connected to support columns;

[0007] The pushing mechanism is arranged on the bottom plate and is used for unloading the formed products.

[0008] The top ends of the two connecting rods are fixedly connected to the bottom ends of the two bottom blocks, and the top ends of the two connecting rods are respectively fixedly connected to the bottom ends of the two bottom blocks. The top plate is provided with two sliding holes, and the top ends of the two bottom blocks respectively pass through the two sliding holes and are fixedly connected to the bottom sides of the same push plate, and the bottom of the push plate is slidably connected to the top of the top plate.

[0009] In a possible design, two stoppers for limiting the formed products are fixedly connected to one side of the push plate, and the bottoms of the two stoppers are slidably connected to the top of the same top plate.

[0010] In a possible design, a heat insulating pad is provided on one side of the push plate and the side close to the two stoppers, and the material of the heat insulating pad is set to be silicone material.

[0011] In a possible design, the two bottom blocks are respectively slidably sleeved with positioning rods, both ends of the two positioning rods are fixedly connected to a No. 1 connecting plate, and the tops of the four No. 1 connecting plates are fixedly connected to the bottom of the same top plate.

[0012] In a possible design, sliders are fixedly connected to both sides of the bottom of the movable plate, and two sliding grooves adapted to the sliders are provided on the top of the bottom plate, and the two sliders are slidably connected to the two sliding grooves respectively.

[0013] In one possible design, a side plate is fixedly connected to one side of the base plate, a ramp is fixedly provided on the top of the side plate to facilitate moving the formed product to the conveyor belt, baffles are fixedly provided on the front and rear sides of the ramp, and the bottom of the side plate is fixedly connected to two support columns.

[0014] In the present application, when in use, the injection molding machine injects the molten plastic into the mold, seals it through the upper mold, and forms a product after cooling and solidification. The external controller starts the electric telescopic rod, and its telescopic end pushes the No. 1 U-shaped frame upward, thereby driving the ejector plate to slide on the inner wall of the mold to eject the molded product from the mold. At the same time, the external controller starts the motor, and its output shaft drives the screw to rotate. Since the moving plate thread sleeve is arranged on the screw, the rotation of the screw is converted into a linear movement of the moving plate, and the moving plate drives the bottom block and the push plate to move toward the mold through the connecting rod, and the push plate is pushed out. The plate slides smoothly on the top plate, pushing the ejected molded product to the inclined block. Under the joint action of the push plate and the stop block, the molded product is pushed onto the inclined block and slides along the inclined block to the conveyor belt, completing the unloading process. Then the external controller starts the motor to reverse, driving the screw to rotate in the opposite direction, so that the moving plate, connecting rod, bottom block and push plate are reset to the initial position, ready for the next unloading cycle. The electric telescopic rod is also reset accordingly, and the ejection plate returns to the inside of the mold. The setting of the positioning rod and the slider increases the stability of the moving plate during movement, ensuring the smooth progress of the pushing action.

[0015] The beneficial effects of the utility model are:

[0016] In the utility model, the pushing mechanism is used to effectively prevent the molded product from accidentally falling during the pushing process, and reduce the safety hazards to the staff. At the same time, it reduces labor costs and improves production efficiency. The setting of the heat insulation pad on the device further protects the product device from the influence of high temperature. BRIEF DESCRIPTION OF THE DRAWINGS
