Description

Technical Field

[0001] The invention relates to the technical field of demoulding, in particular to a device and a working method for removing a thread core of an inverter thread product from a mold sticking thereto. Background Art

[0002] The outer wall of conventional threaded products is mostly a concave-convex groove structure. From the perspective of process assembly and mechanics, the locking and releasing of threaded products require a concave-convex structure to avoid product slippage. The concave-convex structure of the product increases the contact area of ​​the product itself, and the static friction of the product surface during rotation also increases accordingly, making the product easier to rotate. In addition, the outer wall of the product is a symmetrical structure in design. The outer wall profile is basically circular, and the concave-convex groove structure is mostly 3 features, 6 features and 8 features as auxiliary. The inner wall structure of threaded products is all threaded. During injection molding, the core puller and chain drive the thread core to rotate, so that the product can be demolded from the thread core of the mold.

[0003] Before the improvement, during the injection molding process, the product could not be demolded from the mold thread core due to molding parameter adjustment, machine abnormalities, core pulling machine abnormalities, etc., and the temperature of the plastic pellet molding process was high and the mold temperature was high. Under the action of thermal expansion and contraction, the product that was not demolded from the mold thread core would be tightly stuck to the mold thread core and was very difficult to remove. Conventional treatment of such abnormalities relies on external force destruction and clamping with pliers to remove them. Such methods are very likely to cause problems such as mold thread core eccentricity, structural damage, and personnel burns, resulting in the mold being unable to quickly resume production, causing huge cost losses. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a device and a working method for removing the thread core of a mold sticking to an inverter thread product to solve the above problem.

[0005] The technical solution of the present invention to solve the above technical problem is: a device for removing the thread core of the mold of the inverter thread product, comprising a base and an upper cover, wherein the base thread on the base is threadedly connected with the upper cover internal thread on the upper cover; A positioning groove and a paddle positioning groove are respectively opened on the inner side of the base, the paddle positioning groove is connected to the paddle through the paddle rotating shaft, and the positioning groove is connected to the support plate through the positioning block, a spring fixing seat is provided in the base, an upper cover support column is installed on the upper side of the support plate, a spring positioning column is installed on the lower side of the support plate, the spring positioning column is connected to the spring fixing seat through a spring, an upper support block is provided on one side of the upper cover support column, and a lower pressure block is provided directly below the upper support block.

[0006] As a preferred technical solution of the present invention, the outer side of the base is provided with a base external thread, and the outer side of the upper cover is provided with an upper cover external thread.

[0007] As a preferred technical solution of the present invention, a baffle is provided inside the base, a baffle clearance groove is provided between the baffles, and a paddle clearance groove is formed on the support plate.

[0008] As a preferred technical solution of the present invention, the positions of the baffle clearance groove and the paddle clearance groove are adapted to the position of the paddle positioning groove.

[0009] As a preferred technical solution of the present invention, the width of the baffle clearance groove is greater than the width of the paddle.

[0010] As a preferred technical solution of the present invention, the shape of the paddle is "V" shaped.

[0011] As a preferred technical solution of the present invention, a paddle tip is provided at the upper end of the paddle.

[0012] As a preferred technical solution of the present invention, there are at least three spring fixing seats, springs, spring positioning columns and upper cover support columns respectively, and they are arranged at equal intervals.

[0013] As a preferred technical solution of the present invention, there are at least three paddles, and they are arranged at equal intervals.

[0014] As a preferred technical solution of the present invention, a product is provided inside the paddle, and an outer wall groove is provided on the outer side of the product.

[0015] A working method of a device for removing the sticky mold screw core of an inverter threaded product Demoulding process: Step 1, in the free state of the device, the diameter of the baffle is greater than the maximum outer diameter of the product. Place the device on the product with the sticky screw core. Step 2, from the free state to the slightly compressed state, by applying a clockwise torque to the base to drive the rotation of the base structure, the base thread and the internal thread of the upper cover are connected by a threaded manner. During this process, the distance between the upper cover support column on the support plate and the upper cover gradually decreases until it just contacts the inside of the upper cover. Step 3, from the slightly compressed state to the compressed state, as the torque applied to the base continues to increase, the internal thread of the base thread is connected by a threaded manner. During this process, the distance between the upper cover support column on the support plate and the upper cover remains unchanged, and the support plate is driven to compress downward. The positioning block on the support plate moves directionally in the base positioning groove, so as to keep the support plate moving directionally. As the compression continues, the pressing block on the support plate squeezes the paddle to rotate around the paddle rotating shaft, and the paddle tip inserts into the outer wall groove of the product during this process, so that the product is in a locked state inside the device, and the spring is in a compressed state in the spring fixing seat. Rotating the base can demould the product. Product taking process: Step 4, from the compressed state to the slightly compressed state. By applying a counterclockwise torque to the base to drive the rotation of the base structure, the base thread and the internal thread of the upper cover are connected by threading. During this process, the compressed spring releases energy to push the support plate upward. The upper support block of the support plate pushes the dial to rotate around the dial rotation shaft. The pointed knife of the dial moves away from the groove on the outer wall of the product during this process, so that the product is in a free state within the device. Step 5, from the slightly compressed state to the free state. By applying a counterclockwise torque to the base to drive the rotation of the base structure, the base thread and the internal thread of the upper cover are connected by threading. During this process, the upper cover support column on the support plate and the upper cover gradually separate. Step 6, in the free state of the device, the diameter of the baffle is greater than the maximum outer diameter of the product. The device is removed from the product with the sticky screw thread core, and the product is taken out.

[0016] Since the present invention adopts such a structure, it has the following beneficial effects: 1. By using the pointed knife of the dial to be stuck in the concave-convex groove on the outer wall of the product, the friction force of the product is increased, and thus the torque of the product is increased. The torque provided by the device for the product is greater than the static friction force between the product and the screw thread core, so that the product is demolded. 2. It has the advantages of convenient and efficient use, simple operation, and easy to carry, and solves the problem that the product sticks to the screw thread core of the mold.
