Description

Technical Field

[0001] This utility model belongs to the field of molds, and specifically relates to a composite mold for forming motorcycle engine suspension plates with high molding precision and high yield. Background Technology

[0002] Motorcycle engine suspension plate (such as) Figure 2 (As shown) In order to support the suspension of the engine, the plate is relatively thick, and both sides are bent upwards at a large scale. Currently, the forming mold is directly formed by extruding downwards with a punch. This simple and direct extrusion forming can meet certain usage and production requirements, but it also has significant drawbacks. When the sides are bent at a large angle, springback force will be generated, and the bending may not be in place. The bending accuracy is low, the yield rate is low, and it cannot effectively meet the usage and production requirements.

[0003] The technical problem to be solved by this utility model is to provide a composite mold for forming motorcycle engine suspension plates that can compensate for springback, bend in place, bend with high precision, yield rate, and effectively meet the requirements of use and production. Utility Model Content

[0004] To address the problems of springback force, incomplete bending, low bending accuracy, low yield, and inability to effectively meet usage and production requirements when bending at large angles in the prior art, this utility model adopts the following technical solution:

[0005] This utility model provides a composite mold for forming a motorcycle engine suspension plate, including an upper mold base, a main forming punch, a secondary forming punch, a lower mold base, a pair of compensating swing blocks, and a pair of rotating support blocks. The main forming punch and the secondary forming punch are respectively disposed at the bottom of the upper mold base. The lower mold base has several positioning pins in the middle of its upper surface. The product to be processed is fixedly positioned on the lower mold base by the positioning pins. The pair of rotating support blocks are disposed on the lower mold base and located below the main forming punch. The pair of compensating swing blocks are respectively disposed on both sides of the positioning pins. The compensating swing blocks have a central hole in the middle, and the compensating swing blocks are mounted on the rotating support blocks through the central hole via a rotating shaft.

[0006] The beneficial effects of this utility model are as follows: by cooperating with the equipment to compensate for the springback on both sides, the bending accuracy is high, the yield rate is high, and the requirements of use and production are effectively met. Attached Figure Description

[0007] Figure 1 This is a schematic diagram of the structure of one embodiment of the present invention.

[0008] Figure 2 This is a schematic diagram of the product structure to be processed. Detailed Implementation

[0009] The preferred embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0010] Please see Figure 1 A composite mold for forming a motorcycle engine suspension plate includes an upper mold base 1, a main forming punch 2, a secondary forming punch 3, a lower mold base 4, a pair of compensating swing blocks 5, and a pair of rotating support blocks 6. The main forming punch 2 and the secondary forming punch 3 are respectively disposed at the bottom of the upper mold base 1, and a plurality of positioning pins are provided in the middle of the upper surface of the lower mold base 4. Figure 1 (Not visible in the image) The product to be processed is fixedly positioned on the lower die base 4 by positioning pins. The pair of rotating support blocks 6 are located on the lower die base 4 and below the main forming punch 2. The pair of compensating swing blocks 5 are respectively located on both sides of the positioning pins. The compensating swing block 5 has a central hole 51 in the middle. The compensating swing block 5 passes through the central hole 51 and is mounted on the rotating support block 6 through a rotating shaft 52. In this way, the compensating swing block can rotate freely on the rotating support block. During production, the amount of compensation force to be applied by the equipment is set according to the product size. By cooperating with the compensating swing block, the two sides of the product are squeezed, thus compensating for its rebound, resulting in higher bending accuracy and better product yield.

[0011] The beneficial effects of this utility model are as follows: by cooperating with the equipment to compensate for the springback on both sides, the bending accuracy is high, the yield rate is high, and the requirements of use and production are effectively met.

[0012] The above embodiments and figures are not intended to limit the product form and style of this utility model. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of this utility model.
