[0022] The reference numerals in the accompanying drawings include: molding base 1, abutment surface 101, conical surface 102, strip groove 103, first step surface 104, limiting boss 105, second step surface 106, connecting post 107, locking component 2, mounting step 201, molding component 3, and small thin-walled part 4.
[0023] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification.
[0024] This utility model provides a forming fixture for small, thin-walled parts, such as... Figures 1 to 5 As shown.
[0025] In one exemplary embodiment, the forming fixture for a small, thin-walled part includes:
[0026] The molding base 1 has a placement part for placing molding material, and a connecting part 107 is provided in the middle of the placement part. The connecting part 107 protrudes outward along the axial direction of the molding base 1.
[0027] Locking component 2 is installed on connecting part 107, and one end of locking component 2 is used to press the molding material provided on placement part;
[0028] The molding component 3 is used to cover the molding material on the placement part and cooperate with the molding base 1 to extrude the molding material to form a thin-walled part.
[0029] In use, the molding material is placed on the placement part, and then the locking component 2 is installed on the connecting part 107, pressing the end of the molding material. Afterwards, the molding component 3 is installed, so that the inner wall of the molding component 3 fits against the placement part to compress the molding material, forming a thin-walled part. The entire process is simple to operate, and the overall structure of the molding fixture is simple, with fast molding speed, easy movement and handling, and requires few parts, effectively reducing the molding cost of small thin-walled parts 4. Furthermore, product molding can be performed automatically after the design drawings are completed, making product molding convenient.
[0030] In this embodiment, the locking component 2 not only serves to shape the end of the molding material, but also to press and limit the molding material to prevent the molding material from being deformed when the molding component 3 and the molding base 1 are molded together.
[0031] In one exemplary embodiment, from the placement portion to the connecting portion 107, the placement portion includes an abutment surface 101 and a placement step arranged sequentially. The abutment surface 101 is used for the end of the molding component 3 to abut against, and the placement step is used for placing molding material.
[0032] In this embodiment, the abutment surface 101 is provided to abut against the molding component 3 when the molding component 3 is molding the molding material, thereby limiting the stroke of the molding component 3 and ensuring the molding shape of the small thin-walled part 4.
[0033] In an exemplary embodiment, the placement step includes a conical surface 102 for the outer ring of the molding material and a first step surface 104 for the end forming of the molding material. The diameter of the conical surface 102 decreases linearly (or gradually decreases) from the placement portion to the connecting portion 107.
[0034] It should be noted that the shape and size of the conical surface 102 and the first stepped surface 104 determine the molded shape of the product. The conical surface 102 is designed to give the molded product a certain taper. The first stepped surface 104, in conjunction with the locking component 2, achieves end forming of the molding material.
[0035] In an exemplary embodiment, a strip groove 103 is provided on the conical surface 102 along the taper direction, and the strip groove 103 is distributed circumferentially along the conical surface 102.
[0036] It is worth noting that during the molding process of small thin-walled parts 4, the molding material will be compressed and deformed, and the strip groove 103 provides molding space for excess molding material during molding.
[0037] For example, the width of the groove 103 can be reduced as the diameter of the conical surface 102 decreases.
[0038] For example, the corresponding molding surface within the molding component 3 matches the shape of the conical surface 102.
[0039] In an exemplary embodiment, from the placement portion to the connecting portion 107, the connecting portion 107 includes a limiting boss 105 with a diameter decreasing sequentially and a connecting post 107, and the connecting post 107 is provided with a thread for connecting with the locking member 2.
[0040] In this embodiment, the setting of the limiting boss 105 realizes the stroke limitation of the locking component 2, thereby limiting the clamping force of the locking component 2 on the molding material.
[0041] In an exemplary embodiment, a limiting boss 105 is disposed at the center of the first step surface 104, and a second step surface 106 for the locking member 2 to abut against the limiting boss is disposed at the end of the limiting boss away from the first step surface 104.
[0042] In this embodiment, the limiting boss 105 serves to position the locking component 2 during installation, and the second step surface 106 is used for the locking component 2 to abut against.
[0043] In an exemplary embodiment, the locking member 2 includes a pressing part and a threaded connection part. The pressing part is used to press the end of the molding material onto the first stepped surface 104, and the threaded connection part is used to be threadedly connected to the connecting post 107.
[0044] In this embodiment, the locking component 2 is threadedly connected to the connecting post 107 to lock the position of the molding material.
[0045] In one exemplary embodiment, an installation step 201 is provided on the outer wall of the locking member 2.
[0046] In this embodiment, the step 201 is provided so that a tool can be inserted into the molding part 3 to tighten the locking part 2.
[0047] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
