Abstract
Description
Technical Field
[0001] The utility model relates to the field of automobile moulds, in particular to a left-right combined mould drawing mould for a drainage groove. Background Art
[0002] The front of a car usually refers to the body shell at the front of the vehicle, including the part around the front windshield, the front bumper, the front lights and other components. A drainage trough is set below the ventilation cover of the front of the car. The drainage trough is located inside the cabin. When the user washes the car or drives in heavy rain, rainwater will flow into the drainage trough below the ventilation cover along the window glass and the A-pillar. The external water flow is discharged in time through the drainage trough to prevent the water flow from entering the passenger compartment. The end groove of the drainage trough is a groove with one end open. It is usually made by stamping a stamping die. The stamping process includes multiple steps. The last step is to draw the stamped cabbage to form a groove with one end open. The current stamping die often has uneven force at the drawing position due to the precision errors caused by mold closing and workpiece positioning during the drawing process, resulting in micro cracks in the workpiece. There is a risk of leakage when it is assembled to the body later. Utility Model Content

DETAILED DESCRIPTION
[0018] Example 1, see the attached specification Figure 1-4 A left-right clamping drawing die for a drainage trough comprises an upper die base 01, a lower die base 02 and a pressure edge seat 03. A sliding cavity is arranged in the lower die base 02, and the pressure edge seat 03 is slidably installed in the sliding cavity. A plurality of elastic buffers are evenly arranged between the sliding cavity and the pressure edge seat 03. Under the action of these elastic buffers, the pressure edge seat 03 can slide down the mountain in the sliding cavity. A supporting die core 21 is arranged in the middle of the sliding cavity. A die hole 31 matching the size of the supporting die core 21 is arranged in the middle of the pressure edge seat 03. The die hole 31 slides into the sliding cavity. On the supporting mold core 21, a lower drawing mold core 32 is provided at the upper end of the mold hole 31, and the inner edge of the lower drawing mold core 32 matches the edge size of the supporting mold core 21; a lower pressing mold core 11 corresponding to the supporting mold core 21 is provided in the middle of the upper mold base 01, and the lower pressing mold core 11 can be matched and sleeved on the supporting mold core 21, and an upper drawing mold core 12 is provided on the outer side of the lower pressing mold core 11; L-shaped parts 33 are provided on both sides of the end of the lower drawing mold core 32, and the vertical column of the L-shaped part 33 is a limiting column, and a guide inclined surface is provided on the upper end of the limiting column.
[0019] Lower limit blocks 22 are provided at the four corners of the lower mold base 02, and upper limit seats 14 are provided at the four corners of the upper mold base 01. When the mold is closed, the upper limit seat 14 is pressed on the lower limit block 22 to provide a limit for the upper mold base 01 and the lower mold base 02, thereby ensuring that the mold base provides appropriate stamping pressure for the upper and lower mold cores.
[0020] The four corners of the lower mold base 02 are hinged with support members 23 that can be turned upside down. The support member 23 is a square tube. When the mold is stored or transported, it is rotated and turned upward to support it between the upper and lower molds to avoid friction between the upper and lower mold cores, thereby protecting the mold cores. The upper mold base 01, the lower mold base 02 and the edge pressure seat 03 are provided with lifting ears 61 on the side surfaces of both ends to facilitate assembly, disassembly or transportation and transfer between mold bases.
[0021] The working process of the mold is: the workpiece is placed on the supporting mold core 21, and the L-shaped part 33 provides limiting support for the outside of the workpiece to ensure that it is in an accurate stamping position, and then the upper mold base 01 is driven to move downward. After the middle part of the workpiece is pressed between the lower pressing mold core 11 and the supporting mold core 21, the upper drawing mold core 12 presses the workpiece against the surface of the lower drawing mold core 32 and compresses the edge holder 03 downward. The edge holder 03 moves downward in the sliding cavity of the lower mold base 02, and the middle part of the workpiece is in a fixed state, and the edge part is drawn downward by the upper and lower drawing mold cores 32. After the drawing is completed, the upper mold base 01 moves upward to release the workpiece, and the workpiece is released. The edge holder 03 resets upward under the action of the elastic buffer, and the workpiece is ejected and automatically returned.
[0022] Example 2, see the attached specification Figure 1 , 3 -4. This embodiment is based on the first embodiment, with intermediate slides 51 being provided at both ends of the edge pressing seat 03, a lower slide groove 52 corresponding to the intermediate slide 51 being provided at the end of the lower mold base 02, an intermediate slide groove 53 being provided in the intermediate slide groove 53, and an upper slide 54 corresponding to the intermediate slide groove 53 being provided at the end of the upper mold base 01. During mold closing and drawing, the upper slide 54 slides downward into the intermediate slide groove 53, and after the edge pressing seat 03 is compressed, the intermediate slides 51 at both ends thereof slide downward into the lower slide groove 52, forming a two-stage guiding structure.
[0023] Vertical slide bars 41 are provided on both sides of the lower mold base 02, and sliding sleeves 42 are correspondingly provided at the edge of the pressure seat 03. The vertical slide bar 41 is inserted into the sliding sleeve 42. When the pressure seat 03 is compressed and moves downward, the vertical slide bar 41 slides relative to the sliding sleeve 42, and the sliding guide of the pressure seat 03 is improved on both sides. A number of circular gaskets A 34 are evenly provided on the outer side of the lower drawing core 32, and circular gaskets B 13 are provided at corresponding positions on the upper mold base 01. During the mold closing process, each circular gasket A 34 is matched and pressed on each circular gasket B 13, and the balance after the upper and lower mold cores are contacted is maintained by these gaskets. An arc-shaped notch 43 is provided on the side of the pressure seat 03, and the sliding sleeve 42 is arranged at the lower part of the arc-shaped notch 43.
[0024] During the drawing process of the workpiece, the guide vertical rods between the two sides of the edge holder 03 and the lower mold base 02 generate guide supports, and the sliding grooves and sliding seat mechanisms that slide between the edge holder 03 and the two ends of the two mold bases form guide supports. The sliding guide mechanisms at both ends and both sides are used to control the balance of the pressed sliding of the edge holder 03, reduce the deviation during its sliding process, and improve the accuracy of mold closing and drawing.
