Description

Technical Field

[0001] This utility model relates to the field of hole-flipping mold technology, specifically to a flow guide ring hole-flipping mold with a built-in clamping structure. Background Technology

[0002] The guide ring turning die is a special die used to process the turning hole structure on the guide ring component. Its core function is to form a vertical edge on the edge of the hole of the guide ring through the stamping process to meet specific functional requirements.

[0003] During the design process of this utility model, the following problems were found in the existing technology: When the equipment is turning holes in the parts, most of the existing molds are directly pressed down to turn the holes, and most of them do not have a clamping function. As a result, the parts are directly subjected to a large downward pressure, causing the parts to shake and shift, which affects the quality of the pressed-out finished products. Utility Model Content

[0004] The purpose of this invention is to provide a guide ring turning mold with a built-in clamping structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a guide ring flipping mold with a self-clamping structure, comprising a lower base plate, a baffle plate installed on the upper end of the lower base plate, a central column provided on one side of the baffle plate, a support plate installed on the upper end of the central column, a lower mold installed on the upper end of the support plate, an upper molded surface block provided on the upper end of the lower mold, a punch provided on the upper end of the upper molded surface block, a transition plate connected to the upper end of the punch, an upper base plate installed on the upper end of the transition plate, a Misumi guide post assembly installed at the bottom of the upper base plate, a Misumi rectangular spring provided on one side of the Misumi guide post assembly, and an upper mold connecting rod provided on one side of the Misumi rectangular spring.

[0006] The beneficial effects of this utility model are as follows: by adding a Misumi rectangular spring and a punch, when the equipment is pressing down to flip the hole, the Misumi rectangular spring will drive the upper mold block to press down in advance, so that the punch can position the part and prevent the part from shaking or shifting during the flipping process.

[0007] To achieve fixed positioning of the upper surface block:

[0008] Further configuration: the Misumi guide pillars are symmetrically installed about the transverse centerline of the upper base plate, and the Misumi guide pillars penetrate the upper surface block.

[0009] By adopting the above technical solution, during equipment installation, the upper molded block is fixed and limited by inserting the MISUMI guide post assembly into the insertion hole on the lower mold and inserting it into the insertion hole on the lower mold through the upper molded block.

[0010] To achieve the connection between the transition plate and the upper surface block:

[0011] Further configuration: The upper mold connecting rods are symmetrically installed about the transverse centerline of the upper mold block.

[0012] By adopting the above technical solution, when the equipment is in use, the upper mold block is connected to the transition plate through the upper mold connecting rod, so that the transition plate remains vertically raised and lowered when pressed down, preventing the spring from failing during operation.

[0013] To achieve the positioning of the punch on the material part:

[0014] Further configuration: The bottom of the punch penetrates the upper mold block to insert into the groove on the lower mold.

[0015] By adopting the above technical solution, when the upper die is pressed down, the guide boss at the bottom of the punch will first pass through the hole on the part to position the part and prevent the part from shifting or shaking when the hole is turned.

[0016] To achieve the rebound of the support plate after pressing:

[0017] Further configuration: The transition plate is configured as an elastic structure using Misumi rectangular springs.

[0018] By adopting the above technical solution, when the upper mold is pressed down to make a hole, the Misumi rectangular spring expands and contracts, which can provide the mold with a continuous and stable rebound force during the hole-making process, while ensuring that the material remains stable in the mold, reducing mold wear, and protecting the material from excessive compression.

[0025] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.

[0026] Please see Figures 1 to 4 The guide ring turning mold with a built-in clamping structure includes a lower base plate 1, a baffle plate 2 installed on the upper end of the lower base plate 1, a central column 3 on one side of the baffle plate 2, a support plate 4 installed on the upper end of the central column 3, a lower mold 5 installed on the upper end of the support plate 4, an upper molded surface block 6 on the upper end of the lower mold 5, a punch 7 on the upper end of the upper molded surface block 6, a transition plate 8 connected to the upper end of the punch 7, an upper base plate 9 installed on the upper end of the transition plate 8, a Misumi guide post assembly 10 installed at the bottom of the upper base plate 9, a Misumi rectangular spring 11 on one side of the Misumi guide post assembly 10, and an upper mold connecting rod 12 on one side of the Misumi rectangular spring 11.

[0027] In this embodiment, as Figure 1 and Figure 2 As shown, the Misumi guide post assemblies 10 are symmetrically installed about the transverse centerline of the upper base plate 9, and the Misumi guide post assemblies 10 penetrate the upper molded surface block 6.

[0028] In this embodiment, as Figure 1 As shown, the upper mold connecting rods 12 are symmetrically installed about the transverse centerline of the upper mold block 6.

[0029] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, the bottom of the punch 7 penetrates the upper mold block 6 to insert into the groove on the lower mold 5.

[0030] In this embodiment, as Figure 1 and Figure 2 As shown, the transition plate 8 forms an elastic structure through the Misumi rectangular spring 11.

[0031] The working process of this guide ring flipping mold with its own clamping structure is as follows:

[0032] First, the lower die 5 is fixed on the lower platform of the four-column hydraulic press, and the upper die is fixed on the upper platform of the four-column hydraulic press. Then, the product part is placed on the lower die 5. The product and the groove on the lower die 5 are aligned using the profile. Then, the upper die is pressed down to drive the punch 7 to press down. When the upper die is pressed down, the guide boss at the bottom of the punch 7 will first pass through the hole on the part to position the part. Then, the platform continues to drive the upper profile block 6 to move downward. The upper profile block 6 slowly presses and limits the part through the Misumi rectangular spring 11. Then, the platform continues to drive the transition plate 8 and the punch 7 to press down to flip the part by pressing.
