Description

Technical Field

[0001] The utility model relates to the technical field of molds, and more specifically, to a positioning component and a mold. Background Art

[0002] The working principle of a stamping and drawing die is to place a sheet (such as a steel sheet or an aluminum sheet) in the mold cavity of the lower die, and use the punching force of the upper die to punch out the shape of the part. The better the consistency of the position of the sheet placed in the lower die cavity each time, the better the production stability and the more guaranteed the quality.

[0003] The prior art discloses a stamping die for sheet metal bending. On the left and right sides of the top of the bending concave die, two sets of side pulling and fixing blocks with the same structure are symmetrically arranged. The side pulling and fixing block includes a side pulling plate fixedly connected to the top of the bending concave die. A limiting spring is fixedly connected to the outer wall of the side pulling plate, and the other end of the limiting spring is fixedly connected to a sheet fixing member. The sheet is fixed on the bending concave die through the side pulling and fixing block, so as to avoid bending of other parts of the sheet and solve the problem of bending at the position that does not need to be bent. This device uses a limiting spring and a sheet fixing member to fix the sheet. During stamping, the limiting spring still allows the sheet to have a certain moving space, so it is difficult to ensure the quality consistency of the parts obtained after each stamping. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a positioning component and a mold to improve the quality consistency of the parts obtained after each stamping.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] A positioning component includes a linear driving mechanism, a pushing component, and a limiting component for restricting the moving distance of the pushing component; the limiting component is installed on the linear driving mechanism, and there is a pushing space between the limiting component and the output end of the linear driving mechanism; one end of the pushing component is located in the pushing space and is connected to the output end of the linear driving mechanism.

[0007] According to the above technical means, when the positioning component provided by the utility model is in use, the linear driving mechanism is started to drive the pushing component to move; when the pushing component moves, the limiting component restricts the moving distance of the pushing component, which can improve the consistency of the moving stroke of the pushing component each time, so as to control the moving stroke of the pushing component more precisely.

[0008] Further, the limiting component includes a guiding block and a limiting block for limiting the moving distance of the pushing component. The guiding block is arranged on the linear driving mechanism, the pushing component is slidably mounted on the guiding block, the limiting block is arranged on the guiding block, and there is a pushing space between the limiting block and the output end of the linear driving mechanism. When the pushing component moves, the guiding block guides the movement of the pushing component. At the same time, after moving to the required stroke, the limiting block restricts the further movement of the pushing component, so that the moving distance of the pushing component is the distance between the output end of the linear driving mechanism and the limiting block, making the control more precise.

[0009] Further, the pushing component includes a transmission plate and an abutting component arranged on the transmission plate. A clamping groove is arranged on the transmission plate, the clamping groove is clamped with the guiding block, the transmission plate is slidably connected with the guiding block, and the transmission plate is connected with the output end of the linear driving mechanism. The transmission plate is clamped on the guiding block through the clamping groove, and the guiding block supports the transmission plate, making the bottom of the transmission plate suspended, reducing the resistance of the transmission plate movement, making the movement of the transmission plate smoother, and improving the production rhythm.

[0010] Further, there are two groups of limiting components, and the two groups of limiting components are symmetrically installed and connected on the opposite two sides of the linear driving mechanism respectively. Clamping grooves are vertically arranged on both sides of the transmission plate, and the upper and lower surfaces of the two clamping grooves are respectively abutted against the upper and lower surfaces of the two guiding blocks. The two groups of limiting components support the transmission plate more stably, making the movement of the transmission plate smoother.

[0011] Further, the abutting component includes a linkage block, a mounting plate and an abutting plate arranged on the mounting plate. The linkage block is arranged on the transmission plate. A plurality of adjustment holes are arranged on the mounting plate. A first fastener is arranged on the mounting plate and is located in one of the adjustment holes. The mounting plate is fixedly connected with the linkage block through the first fastener. By setting the adjustment holes, the position of the abutting plate on the linkage block can be adjusted, so that the distance between the abutting plate and the required positioning plate can be adjusted.

[0012] Further, a fine-tuning groove is formed on the guiding block, a second fastener is arranged on the guiding block and is located in the fine-tuning groove. The guiding block is fixedly connected with the linear driving mechanism through the second fastener. By setting the fine-tuning groove, the installation position of the guiding block on the linear driving mechanism can be adjusted, so as to finely adjust the distance between the limiting block and the output end of the linear driving mechanism, and the pushing stroke can be finely adjusted.

[0013] Furthermore, the abutting plate has a vertically arranged pushing portion and a guiding portion inclined towards the linear driving mechanism. The lower end of the pushing portion is connected to the mounting plate, and the upper end of the pushing portion is connected to the guiding portion. The guiding portion guides the sheet material, making it more convenient to place the sheet material from above; during positioning, the pushing portion pushes the sheet material.

[0014] Furthermore, the linear driving mechanism includes a fixing plate and a driving cylinder provided on the fixing plate. The guiding block is provided on the fixing plate, and the pushing assembly is connected to the output end of the driving cylinder. The driving cylinder has a faster speed and can shorten the production cycle.

[0015] A mold includes a lower mold and a fixing assembly installed on the forming surface of the lower mold, and further includes the positioning assembly described above; the positioning assembly is installed on the forming surface of the lower mold through the linear driving mechanism, and the fixing assembly and the positioning assembly are respectively located on opposite sides of the forming surface of the lower mold.

[0016] According to the above technical means, for a mold provided by the present utility model, when positioning the sheet material, the sheet material is placed between the fixing assembly and the positioning assembly, and the linear driving mechanism is started to drive the pushing assembly to move, pushing the sheet material towards the fixing assembly, so that the position of each placed sheet material is basically the same, and the sheet material is clamped and fixed during the stamping process, improving the quality consistency of the parts obtained after each stamping.

[0017] Furthermore, the fixing assemblies are provided on three sides of the forming surface of the lower mold. The fixing assembly includes at least two fixing plates; each fixing plate has a vertically arranged fixing portion and a second guiding portion inclined towards the outside of the lower mold. The lower end of the fixing portion is connected to the lower mold, and the upper end of the fixing portion is connected to the second guiding portion. The setting of the second guiding portion facilitates the sheet material to fall from above the lower mold onto the forming surface of the lower mold; by arranging the fixing assemblies or positioning assemblies on all four sides, the sheet material can be positioned on all four sides; by setting two fixing plates, the positioning effect on the sheet material can be further improved, making it difficult for the sheet material to skew during the pushing process of the positioning assembly.

[0018] Compared with the prior art, the beneficial effects are:

[0019] 1. For a positioning assembly and a mold provided by the present utility model, by setting the limiting assembly, the limiting assembly restricts the moving distance of the pushing assembly, which can improve the consistency of the moving stroke of the pushing assembly each time, thereby controlling the moving stroke of the pushing assembly more precisely.
