Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of hot pressing forming equipment, and particularly relates to a die pressing production line for producing external adjusting pieces. Background Art
[0002] There are two production methods for external adjusting piece parts of high-temperature resin matrix composites cured at temperatures above 370°C: one is autoclave molding, and the other is hot die pressing. For products with the same structure and materials similar to external adjusting pieces, the advantages of products formed by hot die pressing compared to those formed by autoclave molding are that the fiber volume fraction is high, the mechanical strength is good, the surface finish of the inner and outer surfaces of the products is relatively high, and the limitations of high-temperature auxiliary materials and equipment used during molding are small. Therefore, for composite material products with a structure similar to that of external adjusting pieces, most actual production adopts the hot die pressing process. By placing the prepreg used for producing external adjusting pieces between the upper die body and the lower die body, electrically heating the upper die body and the lower die body, and conducting heat from the upper die body and the lower die body to the prepreg, the prepreg is heated and cured to obtain blanks of products such as external adjusting pieces.
[0003] The existing hot die pressing process for external adjusting pieces has problems such as a long production cycle for a single part, a long occupation time of the press, and low production efficiency. For each piece of equipment of a single press, 1 operator needs to be equipped for real-time control. For mass production, using a single press will increase labor costs; moreover, the raw material cost of parts cured at temperatures above 370°C is relatively high, and the product qualification rate of manual control using a single press is greatly affected by human factors, which is not suitable for mass production of external adjusting piece type parts. Simply increasing the number of presses will correspondingly increase the losses of labor and materials. Therefore, there is an urgent need for a die pressing production line for producing external adjusting pieces to solve the problems of low production efficiency and high production cost when producing parts of the external adjusting piece type.
[0004] In view of this, the present utility model is specifically proposed. Content of the Utility Model

The second upper clamping device is arranged on one side of the second upper table surface close to the upper die body 11 and is movably connected to the second upper table surface.
[0033] Furthermore, the pressure-holding and cooling-down station 4 includes a third upper table surface fixedly connected to the press head of a third press, and a third upper clamping device for clamping the upper die body 11.

[0035] Further, the mold opening station 6 includes a fourth press upper table fixedly connected to the fourth press ram, and a fourth upper clamping device for clamping the upper mold body 11. The fourth upper clamping device is arranged on one side of the fourth press upper table close to the upper mold body 11 and is movably connected to the fourth press upper table;
[0036] The mold opening station 6 is also fixedly provided with a second press lower table and a second lower clamping device for clamping the lower mold body 13.

[0037] Specifically, as shown in Figures 2 - 4 As shown, the press upper table 8 is movably connected to the clamping device 15, and the press lower table 14 is movably connected to the clamping device 15. The press upper table 8 has the same structure as the first press upper table, the second press upper table, and the third press upper table. The clamping device 15 has the same structure as the first upper clamping device, the second upper clamping device, the third upper clamping device, the first lower clamping device, and the second lower clamping device. The press lower table 14 has the same structure as the first press lower table and the second press lower table.
[0038] As shown in Figure 1 As shown, this embodiment also provides a method for using the molding production line, and the specific process is as follows:
[0039] First, manually place the prepreg for product 12 production into the upper mold body 11 and the lower mold body 13, close the upper mold body 11 and the lower mold body 13, and make the mold body group enter the preheating station 1. The lower mold body 13 is locked and positioned with the first press lower table through the first lower clamping device. Then, insert the thermocouple 9 and the electric heating rod 10 into the reserved holes on the upper mold body 11 and the lower mold body 13 through the connection ports, and then heat up and preheat through the electric heating rod 10, and monitor the temperature through the thermocouple 9. As shown in Figure 2 As shown.
[0040] When the upper mold body 11 and the lower mold body 13 are heated to the predetermined process temperature, the control system automatically identifies and controls the first press lower table to drive the upper mold body 11, the lower mold body 13, and the product to be transported to the pressurization and heating station 2 through the running track 7. After the first press upper table and the upper mold body 11 are locked and positioned through the first upper clamping device, the press at the pressurization and heating station 2 automatically performs repeated pressurization and pressure relief operations to discharge the small molecule gases generated by the reaction, and presses the product 12 to the required thickness. At the same time, monitor the temperature of the mold body through the thermocouple 9.
[0041] When the temperature reaches the curing temperature of the product 12, the first upper clamping device that locks the upper die body 11 with the upper table surface of the first press is released, and it is transferred from the pressurization and heating station 2 to the heat preservation and pressure holding station 3 through the running track 7. The upper table surface of the second press at the heat preservation and pressure holding station 3 drops, and is locked with the upper die body 11 through the second upper clamping device, and the product 12 is pressurized to the required process pressure for heat preservation to complete curing, and the temperature of the die body is monitored through the thermocouple 9. See Figure 4 as shown.
[0042] After the product 12 completes heat preservation at the heat preservation and pressure holding station 3, the second upper clamping device that locks the upper die body 11 with the upper table surface of the second press is released, and it is transferred from the heat preservation and pressure holding station 3 to the pressure holding and cooling station 4 through the running track 7. The upper table surface of the third press at the pressure holding and cooling station 4 drops, and is locked with the upper die body 11 through the third upper clamping device, and the product 12 is pressurized to the required process pressure and the temperature is controlled for cooling, and the temperature of the die body is monitored through the thermocouple 9.
[0043] When the product 12 cools down to the predetermined temperature, the third upper clamping device that locks the upper die body 11 with the upper table surface of the third press is released, and it is transferred from the pressure holding and cooling station 4 to the air cooling station 5 through the running track 7, and external blowing is used for forced cooling, and the temperature of the die body is monitored through the thermocouple 9.
[0044] When the temperature of the product 12 drops to the predetermined temperature, the interface of the thermocouple 9 and the electric heating rod 10 is disconnected, and the first lower clamping device that locks the lower die body 13 with the lower table surface of the first press is released; the upper die body 11, the product 12 and the lower die body 13 are transported to the mold opening station 6 by a forklift or a crane, etc. The upper die body 11 and the upper table surface of the fourth press are locked through the fourth upper clamping device, and the lower die body 13 and the lower table surface of the second press are locked through the second lower clamping device, and then the upper die body 11 is opened by the press to take out the product 12, and the demolding of the product is completed.
[0045] The preheating station 1 to the air cooling station 5 serve as a molding production line, and one mold opening station 6 can cooperate with the products 12 of multiple molding production lines for demolding at the same time.
[0046] The design of the molding production line for producing external adjusting pieces of the present utility model greatly improves the production efficiency of products, reduces the production cost of batch products, and improves the production quality of products.
