[0002] As shown in the accompanying drawings of the present application Figure 4 As shown in the accompanying drawings of the present application

[0003] However, because the product has only three outer sides, and there are U-shaped grooves and some USB holes, it needs to go through many heating and hot pressing, cold pressing and shrinkage prevention processes to gradually complete the product. In this production process, due to the product structure, internal stress shrinkage is uneven, and there are some uncertain factors. The cooperation with the real machine is not very ideal. The PU characteristic coating of small geometry is generally difficult to adhere to the real machine, and there is a possibility of rebound. In particular, the upper end of the real machine is not very in place with the real machine geometry matching. The upper end will deform outward by a certain value due to the geometry, so it needs to be added to the reverse type geometry hot pressing pressure setting. According to the conventional, it is impossible to meet the type requirement. INVENTION CONTENTS

DETAILED DESCRIPTION

[0019] The embodiment of the utility model will be further described in detail below in combination with the drawings and examples. The following examples are used to illustrate the utility model, but cannot be used to limit the scope of the utility model.

[0020] As Figures 1 to 3As shown, a U-shaped open-type folding mobile phone PU protective case precision molding mold includes an upper template 1, a guide sleeve 2 embedded at the corner of the upper template 1, and a fiberglass heat insulation plate 3 fixed below the upper template 1. A heating tube 4 and a matching temperature sensing wire assembly are arranged below the fiberglass heat insulation plate 3. A lower template 5 is arranged below the upper template 1, and a guide post 6 that cooperates with the guide sleeve 2 is fixed on the side of the lower template 5. A fixed base 7 is fixed above the lower template 5, and an adjustable support plate 8 is arranged on the fixed base 7. The adjustable support plate 8 includes a support plate, a pressure block and a gasket. A lower mold fixing plate 9 is fixed above the fixed base 7, and a copper sleeve 10 is connected to the lower mold fixing plate 9 through a guide pin. A fiberglass handle 11 is connected to the lower mold fixing plate 9, and an adjustment block 12 is added to the side of the fiberglass handle 11. A mold alignment pin 13 is assembled on the lower mold fixing plate 9 to ensure that the coordinates of the upper and lower molds are consistent.

[0021] Working principle: The upper template 1 moves up and down on the guide post 6 via the guide sleeve 2. There is a fiberglass heat insulation plate 3 under the upper template 1. Under the fiberglass heat insulation plate 3, there is an upper mold plus heating tube 4 and temperature sensing wire assembly to realize the heating function. The temperature is transmitted to the Dummy+ fiberglass assembly 11 in the mold closing state, which can heat the product to a high temperature state and hot press the product to form the required geometric shape. By setting the limit post and the adjustable shim below, the height of the upper and lower hot pressing can be adjusted. The lower template 5 is fixed to the guide post 6 under the servo machine to guide the up and down movement. The fixed base 7 fixes the entire lower mold on the lower template 5. The adjustable support plate 8 + pressure block + shim on the fixed base 7 can be used to fine adjust the X, Y front and back left and right, such as processing error and cumulative error, so that it can be finely adjusted.

[0022] The Dummy+ 11-component fiberglass kit conforms to the geometry of the product and can be adjusted as needed, as per the instruction manual. Figure 3 As shown in the enlarged view, a 1-degree gradient reverse slope was applied to the upper part of the image. Two interference points of 0.1mm were created between the product and the dummy, as shown in the image. The upper perimeter of the 0.1mm interference was shaped to be flush with the surface. The corners of the three sides of the 0.1mm interference were difficult to achieve precisely, so interference shaping was used to allow space for better fit and more contact with the machine. Fiberglass 11 provides excellent heat insulation. A copper sleeve 10 is located under the lower mold for easy removal and placement of the product, while another part is used for hot pressing, improving production efficiency. The lower mold fixing plate 9 is connected to the copper sleeve 10 by guide pins for positioning and fixing. The adjustable support plate 8, pressure block, and shims are used. The adjusting block 12, under the influence of the opposing force, will move towards the U-shaped opening, causing some inconsistencies in the inner side pressure. Therefore, the adjusting block 12 is added to block this movement, and the screws can be adjusted to allow it to move inward, ensuring the inner side is properly compressed to meet testing requirements. The mold pin 13 ensures that the coordinates of the upper and lower molds are the same before the servo machine operates. After mold installation, the mold pin 13 must be removed to improve installation efficiency and provide a reference point. Each of these components operates sequentially to complete production requirements and meet customer needs.

[0023] The embodiments of the present application are given for the purpose of illustration and description, and are not intended to be exhaustive or to limit the application to the forms disclosed. Many modifications and variations will be apparent to those of ordinary skill in the art. Embodiments were chosen and described in order to best explain the principles of the application and its practical application, and to thereby enable others skilled in the art to best utilize the application with various modifications as are suited to the particular use contemplated.
