Description

Technical Field

[0001] The present application relates to the technical field of forming dies, and in particular to a segmented pre-pressing pre-forming die. Background Art

[0002] At present, carbon fiber products are generally produced in the industry using a molding process, which includes the following steps: (1) Cutting process: Cut the pre-impregnated carbon fiber cloth into appropriate shapes and lay the foundation for the subsequent bonding of the carbon fiber cloth and the mold; (2) Heating and shaping process: Heat the pre-impregnated carbon fiber cloth at a lower heating temperature (below 75°C) and a lower pressure (below 0.1MPA), and use a pre-pressing mold to pre-press the carbon fiber cloth so that it can fit the surface of the final mold; (3) Molding process: Place the pre-pressed carbon fiber cloth into the final mold to fit the surface of the final mold. However, when pre-forming complex parts or multi-step parts, the two ends of the mold will first press the carbon fiber cloth, causing the two sides to pull the middle, resulting in the tearing of the carbon fiber cloth.

[0003] Therefore, a segmented pre-compression preforming die with tear-proof properties is provided. Summary of the invention

[0006] When closing the mold, the two first lifting blocks in the middle will fix the middle part of the carbon fiber cloth, and then the two first lifting blocks in the middle will be compressed. At the same time, the first lifting blocks on both sides will fix the carbon fiber cloth on both sides to the upper mold and the first lifting blocks, and then fix the carbon fiber cloth from the middle to both ends, thereby preventing the two ends from borrowing material from the middle and causing the carbon fiber cloth to tear, thus having the effect of preventing tearing.

[0008] Furthermore, the first adjusting member includes: a first spring, two ends of which are respectively fixedly connected to the base and the first lifting block; a screw, a threaded end of which is threadedly connected to the base, and a nut of which abuts against the first lifting block.

[0009] Furthermore, the first lifting block includes a first countersunk hole; the nut of the screw is located in the first countersunk hole.

[0010] Further, the first lifting block includes a first accommodating hole; the base includes a second accommodating hole; one end of the first spring is located in the first accommodating hole, and the other end is located in the second accommodating hole.

[0011] Furthermore, the second lifting block includes a guide groove; the guide block portion is located in the guide groove and is used for guiding the second lifting block.

[0012] Furthermore, the structure of the second lifting member is the same as that of the first lifting member.

[0013] Furthermore, the base includes a groove; the guide block is located in the groove.

[0035] Reference Figure 1-8 A segmented pre-pressing preforming mold 100 includes: an upper mold 101, a base 102, a lower mold 103, a first lifting block 104, a first adjusting member for adjusting the height of the first lifting block 104, a guide block 105, a second lifting block 106, a second adjusting member for adjusting the height of the second lifting block 106, and a guide column 107. The upper mold 101 is located above the lower mold 103, and the lower mold 103 is located above the base 102 and fixedly connected to the base 102. The base 102 includes a groove 102a, and the guide block 105 is located in the groove 102a. The base 102 is provided with a guide hole extending along the height direction of the base 102, and the guide column 107 is partially located in the guide hole and moves along the axial direction of the guide hole.

[0036] The first lifting block 104 is vertically slidably connected to the lower mold 103. Specifically, the lower mold 103 is provided with a first slide groove 103a extending along the height direction of the lower mold 103, and the first lifting block 104 moves along the first slide groove 103a. The guide block 105 is fixedly connected to the base 102. The second lifting block 106 is vertically slidably connected to the guide block 105. Specifically, the second lifting block 106 includes a guide groove 106a, and the guide block 105 is partially located in the guide groove 106a, which is used to guide the second lifting block 106. The guide column 107 is fixedly connected to the upper mold 101. Among them, a plurality of first lifting blocks 104 are provided, and the heights of the plurality of first lifting blocks 104 gradually decrease from the center to both ends, and a plurality of groups of first adjustment members are provided corresponding to the first lifting blocks 104.

[0037] The first adjusting member is used to adjust the height of the first lifting block 104, and includes: a first spring 108 and a screw 109. The two ends of the first spring 108 are fixedly connected to the base 102 and the first lifting block 104 respectively. The threaded end of the screw 109 is threadedly connected to the base 102, and the nut of the screw 109 abuts against the first lifting block 104. The first lifting block 104 includes a first countersunk hole 104a, and the nut of the screw 109 is located in the first countersunk hole 104a.

[0038] The first lifting block 104 includes a first receiving hole 104b, the base 102 includes a second receiving hole 102b, one end of the first spring 108 is located in the first receiving hole 104b, and the other end is located in the second receiving hole 102b. The structure of the second lifting member is the same as that of the first lifting member, and the second adjusting member is used to adjust the height of the second lifting block 106. When the mold is closed, the two middle first lifting blocks 104 will fix the carbon fiber cloth in the middle part, and then the first spring 108 under the two middle first lifting blocks 104 will be compressed until the upper mold 101 abuts against the first lifting blocks 104 on both sides, thereby pressing the carbon fiber cloth on both sides, and fixing the carbon fiber cloth from the middle to both ends in turn, thereby preventing the carbon fiber cloth at both ends from borrowing material from the middle, causing the carbon fiber cloth in the middle to tear, thus having the effect of preventing tearing.

[0039] Working process: When in use, the upper mold 101 is driven down by the hydraulic cylinder, and the upper mold 101 will abut against the two first lifting blocks 104 in the middle, thereby fixing the carbon fiber cloth in the middle part, and then the first spring 108 under the two first lifting blocks 104 in the middle will be compressed until the upper mold 101 abuts against the first lifting blocks 104 on both sides, thereby pressing the carbon fiber cloth on both sides, and fixing the carbon fiber cloth from the middle to both ends in turn (that is, fixing the carbon fiber cloth in sections), thereby preventing the carbon fiber cloth at both ends from borrowing material from the middle, causing the carbon fiber cloth in the middle to tear, so it has the effect of preventing tearing. When multiple first lifting blocks 104 and second lifting blocks 106 are abutted against the upper end of the base 102, the molding of the carbon fiber cloth is completed.
