Description

Technical Field

[0001] The present application relates to the technical field of injection molding, and in particular to an anti-shaking mechanism for inserting hardware into a mold. Background Art

[0002] Injection molds are divided into two types: thermosetting plastic molds and thermoplastic plastic molds according to molding characteristics; they are divided into transfer molds, blow molding molds, casting molds, thermoforming molds, hot pressing molds, injection molds, etc. according to molding processes. Among them, hot pressing molds can be divided into overflow type, semi-overflow type, and non-overflow type according to overflow method. Injection molds can be divided into cold runner molds and hot runner molds according to pouring systems. They can be divided into mobile and fixed types according to loading and unloading methods. Injection molds consist of two parts: movable mold and fixed mold.

[0003] In the patent with the published authorization announcement number CN221022059U, the anti-sway mechanism of the hardware placed in the mold involves the field of injection molding technology, including a slider arranged on the injection molding machine, a fixing plate arranged on the slider, and a plurality of end fixing holes opened on the fixing plate. Compared with the prior art, the present application uses the provided slider and the positioning plate in coordination, first inserts the hardware that needs to be fixed with the injection molding shell into the end fixing hole, and at the same time, inserts the hardware into the middle position of a pair of elastic metal sheets, and the provided pair of elastic metal sheets has a fixing effect on the hardware. For relatively long hardware, the hardware is effectively limited and fixed in the middle section of the hardware, so that the position of the hardware is not easy to deflect when it is placed in the injection mold, and the engine hardware will not be deformed and contacted due to excessive injection pressure when the injection molding machine is working and filling injection molding, thereby improving the yield rate of the injection molding shell and the hardware.

[0004] When the above device is implemented, the stability of fixing the hardware by the elastic metal sheet is insufficient. Since the elastic metal sheet needs to be bent multiple times after use to remove and install the hardware, it will lead to insufficient stability when positioning the hardware later, which will cause shaking and tilting during injection molding. Utility Model Content

[0009] By adopting the above technical solution, the two L-shaped plates can stably position the hardware, and the magnetic attraction principle can further be used to firmly adsorb the hardware to the L-shaped plates, further ensuring the stability of the hardware in the inner cavity of the injection molded shell.

[0010] As a preferred embodiment, the inner wall of the injection-molded housing is symmetrically provided with two insertion holes, and two hardware pieces are plugged into the inner wall positions of the insertion holes, and the outer shape of the hardware pieces is matched with the inner wall shape of the insertion holes.

[0011] By adopting the above technical solution, it is ensured that the hardware will not swing left and right at will when it is inserted into the inner wall of the injection-molded shell, thereby ensuring the stability of the hardware arranged inside the injection-molded shell.

[0012] As a preferred embodiment, a rotation hole is opened in the middle of the abutment plate, the rotation rod is rotationally connected to the inner wall of the rotation hole, and the outer side of the rotation rod is fixedly connected to the outer side of the second positioning plate.

[0013] By adopting the above technical solution, the position of the abutment plate can be rotated at will, thereby ensuring that the abutment plate can be arranged in a parallel state or a staggered state with the second positioning plate.

[0014] As a preferred embodiment, two abutment plates are symmetrically fixedly mounted on the outer side of the injection-molded housing, and one side of the two abutment plates is fixedly connected to positioning plate one and positioning plate three, respectively.

[0015] By adopting the above technical solution, the two contact plates can further position and support the positioning plate one and the positioning plate three, thereby ensuring their firmness, and further ensuring that the positioning plate one and the positioning plate three will not be arbitrarily shifted when subjected to the force of the spring.

[0016] As a preferred implementation, the two positioning pins are inserted into the inner wall positions of the two positioning holes, and the outer edge diameter of the positioning pins is matched with the inner wall diameter of the positioning holes.

[0017] By adopting the above technical solution, it is possible to play a positioning and supporting role on the side of the hardware away from the inner cavity of the injection molding shell, thereby ensuring the positioning effect of the hardware and preventing it from falling at will.
