Description

Technical Field

[0001] The utility model belongs to the field of plastic product manufacturing, and particularly relates to a plastic product button orthopedic device. Background Technique

[0002] At present, many plastic products are provided with buttons to achieve their main functions. In the design requirements of the buttons, the feel of pressing and rebounding needs to be reflected. Therefore, in the design of the shell, a cantilever structure is used at the button, and the root cross-section of the cantilever is relatively small to achieve a large elastic deformation under a small external force. However, during the production process of the plastic shell, the cantilever structure at the button will have a large shrinkage deformation, resulting in insufficient space for pressing the button, and thus poor feel when pressing the button. To solve this problem, after the plastic shell is processed from the injection molding machine and before it is completely cooled and shaped, the cantilever structure at the button is manually supported in the opposite direction with fingers. After it is completely cooled and shaped, the support is released to achieve the desired effect. However, for manual operation, there are problems that factors such as the supporting force and position cannot be precisely controlled, resulting in poor consistency of the button effect. Summary of the Invention

[0003] In view of the deficiencies of the prior art, the utility model provides a plastic product button orthopedic device, which can complete the orthopedic work of the plastic product button with high precision, high efficiency and simple operation on the premise of existing equipment.

[0004] The technical solution of the utility model is: a plastic product button orthopedic device, including a base, a column, and a support bolt. The column is fixed on the base, and a limit convex block is arranged at the center of the top. The two support bolts are arranged on the column and are respectively located on both sides of the limit convex block.

[0005] The technical effect of the utility model is that through a simple and compact structural design, that is, the orthopedic device for the plastic product button, the problem of poor feel caused by the shrinkage deformation of the button cantilever structure is solved. Its operation is simple and the work is stable, effectively improving the consistency of the button effect, and bringing a high-precision and high-efficiency solution to the production process of plastic products with buttons.

[0010] The present utility model will be further described below with reference to the accompanying drawings.

[0011] As Figures 1-3 shown, a button orthopedic device for plastic products includes a base 1, a column 2, and a support bolt 3.

[0012] The base 1 is in the shape of a cuboid and is machined from a metal material. Two countersunk holes 1-1 are provided at intervals from bottom to top at the bottom for installing the column 2;

[0013] The column 2 is in the shape of a cuboid. A limit lug 2-1 is machined at the center of the top. The limit lug 2-1 is rectangular. One upper threaded blind hole 2-2 is provided on each side of the limit lug 2-1 of the column 2, and two lower threaded blind holes 2-3 corresponding to the positions and sizes of the countersunk holes 1-1 of the base 1 are provided at the bottom.

[0014] The support bolt 3 is a cylindrical head bolt. The size of the cylindrical head 3-1 is machined according to the size of the button cantilever to be orthopedically corrected, and the external thread of the screw rod corresponds to the upper threaded blind hole 2-2 on the column 2.

[0015] During assembly, use a socket head screw to pass through the countersunk hole 1-1 and be threadedly connected to the lower threaded blind hole 2-3 of the column 2, and tighten to fix the column 2 on the base 1. The two support bolts 3 are respectively screwed into the upper threaded blind holes 2-2 at the top of the column 2, and the height of the cylindrical head is adjusted according to the orthopedic position of the button cantilever of the plastic product 4.

[0016] During use, place this device on the working platform, quickly place the uncompletely cooled and shaped plastic product 4 processed by the injection molding machine on the top of the column 2, place the limit lug 2-1 in the square hole 4-1 on the plastic product 4, then place the plastic product 4 naturally on the working platform, the two support bolts 3 naturally support at the button cantilever 4-2 of the plastic product 4, and the cylindrical head 3-1 is placed at the center of the button cantilever 4-2. After being completely cooled and shaped, remove the plastic product 4, and the button cantilever 4-2 can be kept in the specified position. By rotating the support bolt 3, the support height can be adjusted to achieve the best effect of the button.
