The material release screw extends into the inner hole and is tightened inside the material support block. A spring is provided on the outer sleeve of the material release screw. The spring is located inside the inner hole and supported on the pressure plate.

[0007] A shim is provided between the bottom of the material support block and the top of the pressure plate. The shim is fitted outside the unloading screw, and the bottom of the spring abuts against the upper surface of the shim.

[0008] Side stops are provided on the outer side of the upper surface of the material support block.

[0016] The principles and features of this utility model are described below with reference to the accompanying drawings. The embodiments described are for illustrative purposes only and are not intended to limit the scope of this utility model. The utility model is described more specifically in the following paragraphs by way of example with reference to the accompanying drawings. The advantages and features of this utility model will become clearer from the following description. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of this utility model.

[0017] It should be noted that when a component is described as "fixed to" another component, it can be directly on the other component or may have a component in between. When a component is considered "connected to" another component, it can be directly connected to the other component or may have a component in between. When a component is considered "set on" another component, it can be directly set on the other component or may have a component in between. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0018] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0020] A core support mechanism for bending, as shown in Figures 1 and 2, includes a support assembly 3 mounted on a profile plate 2 and located below a nylon core 1;

[0021] The lifting assembly 3 includes a pressure plate 31 fixed to the bottom of the mold plate 2 and a material support block 32 mounted on the mold plate 2. The bottom of the material support block 32 is provided with an inner hole 33. A material release screw 34 is provided on the pressure plate 31. The material release screw 34 extends into the inner hole 33 and is screwed into the material support block 32. A spring 35 is provided on the outer sleeve of the material release screw 34. The spring 35 is located in the inner hole 33 and is supported on the pressure plate 31.

[0022] A shim 36 is provided between the bottom of the material support block 32 and the top of the pressure plate 31. The shim 36 is fitted outside the unloading screw 34, and the bottom of the spring 35 abuts against the upper surface of the shim 36.

[0023] The material support block 32 has a T-shaped structure, and a T-shaped groove is provided on the template 2. The material support block 32 is installed in the T-shaped groove of the template 2.

[0024] A side stop 37 is provided on the outer side of the upper surface of the material support block 32.

[0025] The pressure plate 31 is detachably installed on the bottom of the template 2 by fixing screws 38.

[0026] The top sidewall of the T-shaped groove on the template 2 is connected to the sidewall of the template 2.

[0027] When the nylon core 1 is initially formed, both ends are fixed in the corresponding positions. The material support block 32 is placed in the groove of the mold plate 2, i.e., the T-shaped groove. The pressure plate 31 is fixed at the bottom of the mold plate 2. The unloading screw 34 passes through the pressure plate 31, and then passes through the washer 36 and the spring 35 in sequence, and connects with the material support block 32. By adjusting the thickness of the washer 36, the floating height of the material support block 32 can be finely adjusted.

[0028] During normal operation, the spring 35, through preload, lifts the material support block 32. The upper surface of the material support block 32 contacts the bottom surface of the nylon core 1, and the side stop block 37 contacts the side of the nylon core 1. During feeding, the spring supports the nylon core 1 and controls its forward deformation. After feeding, the nylon core 1 is pressed downwards against the material support block 32 as the product is formed. When it reaches the forming position, the bottom surface of the gasket 36 completely overlaps with the upper surface of the pressure plate 31. After forming, the material support block 32 is lifted by the spring 35, lifting the nylon core 1, completing one work cycle.

[0029] This invention utilizes the material support component 3 to support the nylon core 1, thereby increasing the service life of the nylon core 1, improving the product qualification rate, and enhancing the product's competitiveness.

[0030] The present invention has been described above with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any improvements made using the inventive concept and technical solution of the present invention, or direct application to other situations without modification, are all within the protection scope of the present invention.
