Description

Technical Field

[0001] This utility model relates to the field of composite material production technology, and in particular to a molding device for composite material processing. Background Technology

[0002] During the processing and molding of composite materials, multiple layers need to be stacked one by one in the concave mold, and resin is evenly applied between two adjacent layers. Then, the hydraulic telescopic cylinder is operated to push the convex mold down and precisely align it with the concave mold. Water cooling is then used to cool the concave and convex molds, allowing the resin inside to solidify, thereby molding the composite material.

[0003] However, the bonding quality of composite materials is greatly affected by the accuracy of the mating of the concave and convex dies. During mold closing, the concave and convex dies may be misaligned due to mechanical vibration or installation deviation. Operators may find it difficult to detect the misalignment between the convex and concave dies in time, resulting in problems such as uneven thickness and edge defects in composite material products. Utility Model Content

[0005] To achieve the above objectives, this utility model provides a molding device for processing composite materials, including a lower cooling pipe and an upper cooling pipe that are respectively spirally sleeved on the outside of a concave mold and a convex mold.

[0011] The plug-in assembly is located at the bottom of the upper cooling pipe, and the plug-in assembly, the docking assembly, and the push-button switch are coaxially distributed from top to bottom.

[0012] When the mold is precisely closed, the plug-in component moves down and seals with the mating component, connecting them. At the same time, the plug-in component triggers the press switch through the mating component to close and start the water pump. Conversely, if the concave and convex molds are misaligned and connected, the press switch will not be triggered.

[0014] Preferably, the lower connecting pipe is vertically arranged at the top of the lower cooling pipe, and the connection between the lower connecting pipe and the lower cooling pipe is located between the lower ball valve and the bottom sealing plate.

[0015] Preferably, the return spring is sleeved on the bottom end of the insert rod, and the two ends of the return spring are fixed to the insert rod and the bottom sealing plate, respectively.

[0016] Preferably, the trigger tube has opening slots at both the top and bottom, and the trigger tube and the lower tube are coaxial.

When the punch and die are docked, the plug-in assembly and the docking assembly dock simultaneously.

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0031] like Figures 1 to 4 As shown, a molding device for processing composite materials includes a lower cooling pipe 1 and an upper cooling pipe 2, which are respectively spirally sleeved on the outside of a concave mold and a convex mold.

[0032] Water tank 8 is detachably installed on the concave mold, and the end of the upper cooling pipe 2 away from the lower cooling pipe 1 is connected to water tank 8.

[0033] A suction pipe 7 connects the inside and outside of the water tank 8.

[0034] Water pump 6 is located between the top of suction pipe 7 and the bottom of lower cooling pipe 1.

[0035] The push switch 5 is located outside the water pump 6 and is electrically connected between the external wiring of the water pump 6 and the power transmission line of the external power supply.

[0036] The docking component 3 is located at the top of the lower cooling pipe 1.

[0037] The plug-in component 4 is located at the bottom end of the upper cooling pipe 2, and the plug-in component 4, the docking component 3, and the push switch 5 are coaxially distributed from top to bottom.

[0038] During precise mold closing, the insert component 4 moves down and seals with the docking component 3, connecting them. Simultaneously, the insert component 4 triggers the press switch 5 through the docking component 3 to close and start the water pump 6. Conversely, if the concave and convex molds are misaligned, the press switch 5 will not be triggered. In this way, the operator can quickly determine whether there is a large misalignment between the concave and convex molds during mold closing by observing whether the cooling water is circulating. This allows the operator to take timely remedial measures, quickly and efficiently calibrate the position of the concave and convex molds, and reduce the impact of misalignment on the defect rate of composite material products.

[0039] like Figures 1 to 4As shown, the docking assembly 3 includes a lower connecting pipe 31 connected to the top of the lower cooling pipe 1 and a wedge-shaped sleeve 32 fixed to the top of the lower connecting pipe 31. A sealing ring is provided at the top of the lower connecting pipe 31. A lower ball valve 33 is provided inside the lower connecting pipe 31. A trigger tube 35 is inserted through the top of the lower connecting pipe 31. A guide member 34 for guiding the vertical linear movement of the trigger tube 35 is provided at the top of the lower ball valve 33. The guide member 34 includes two vertical guide rails relatively fixed to the top of the lower ball valve 33 and a sliding sleeve slidably mounted on the vertical guide rails. The sliding sleeve is fixed to the trigger tube 35. The trigger tube 35 can move only in the vertical direction. The bottom of the lower tube 31 is fixedly provided with a bottom sealing plate 36. A rod 37 is coaxially inserted on the bottom sealing plate 36. A sealing ring is provided between the bottom sealing plate 36 and the rod 37. The sealing ring is located on the inner wall of the bottom sealing plate 36 that contacts the rod 37. A return spring 38 is provided between the outside of the rod 37 and the top of the bottom sealing plate 36. The return spring 38 is sleeved on the bottom end of the outside of the rod 37, and the two ends of the return spring 38 are fixed on the rod 37 and the bottom sealing plate 36 respectively.

[0040] The lower connecting pipe 31 is vertically positioned at the top of the lower cooling pipe 1, and the connection between the lower connecting pipe 31 and the lower cooling pipe 1 is located between the lower ball valve 33 and the bottom sealing plate 36. This design allows the plug-in assembly 4 and the docking assembly 3 to be precisely connected and communicate with each other, facilitating the flow of coolant from the docking point between the two.

[0041] like Figure 3 and Figure 4 As shown, the trigger tube 35 has opening slots at both the top and bottom, and the trigger tube 35 and the lower connecting tube 31 are coaxial. With this design, when the plug-in component 4 and the docking component 3 are precisely docked, the trigger tube 35 opens the lower ball valve 33 under the thrust of the plug-in component 4 and moves down through the plug rod 37 to trigger the press switch 5, thereby starting the water pump 6. When the cooling water flows to the lower ball valve 33, some of the cooling water can be transported to the plug-in component 4 through the opening slot on the trigger tube 35, increasing the flow rate of cooling water at the lower ball valve 33.

[0042] like Figure 1 , Figure 3 and Figure 4 As shown, the plug-in assembly 4 includes an outer sleeve 46 vertically fixed to the bottom end of the upper cooling pipe 2. An upper connecting pipe 41 is slidably sleeved on the bottom end inside the outer sleeve 46. A sealing ring is also provided between the overlapping parts of the upper connecting pipe 41 and the outer sleeve 46. An external pressure spring 44 is provided between the top end of the outer side of the upper connecting pipe 41 and the end face of the outer sleeve 46. The two ends of the external pressure spring 44 are respectively fixed on the bottom of the outer sleeve 46 and the upper connecting pipe 41. An upper ball valve 42 is provided at the bottom end inside the upper connecting pipe 41. An inner pressure spring 43 is provided between the upper ball valve 42 and the top end inside the upper connecting pipe 41. A wedge-shaped plug 45 is fixed at the bottom end outside the upper connecting pipe 41.

[0043] The size and shape of the wedge-shaped plug 45 match the size and shape of the inside of the wedge-shaped sleeve 32.

[0044] The upper ball valve 42 and the lower ball valve 33 have the same structure. The upper ball valve 42 includes a sealing ring fixed inside the upper pipe 41 and a sealing ball located between the sealing ring and the bottom of the inner pressure spring 43. The two ends of the inner pressure spring 43 are fixed to the top of the sealing ball and the top of the upper pipe 41, respectively. The inner diameter of the inner pressure spring 43 gradually increases from bottom to top, and its overall shape is conical. When the insertion component 4 is not connected to the docking component 3, the sealing ball is pushed by the elastic force of the inner pressure spring 43 to seal inside the sealing ring, preventing external dust or particles from entering the upper cooling pipe 2. The sealing ball in the lower cooling pipe 1 is pushed by the insertion rod 37 and the return spring 38 to seal the sealing ring, and its effect is the same as the former.

[0045] Working principle: When the hydraulic telescopic cylinder pushes the punch and die together, if the punch and die are precisely aligned, the wedge-shaped plug 45 at the bottom of the upper pipe 41 is inserted into the wedge-shaped sleeve 32 until the outer wall of the wedge-shaped plug 45 is fully in contact with the inner wall of the wedge-shaped sleeve 32. During this process, the top of the trigger pipe 35 abuts against the sealing ball of the upper ball valve 42 and pushes the sealing ball to separate from the sealing ring, and simultaneously abuts against the sealing ball of the lower ball valve 33 and pushes the sealing ball to separate from the sealing ring. When the bottom of the upper pipe 41 abuts against the top of the lower pipe 31, the insert rod 37 is pushed down to the lowest position and triggers the press switch 5, connecting the power supply to the water pump 6. The water pump 6 then powers the water tank. The cooling water in tank 8 flows sequentially through suction pipe 7, water pump 6, lower cooling pipe 1, lower connecting pipe 31, trigger pipe 35, upper connecting pipe 41, outer sleeve pipe 46, and upper cooling pipe 2, and finally returns to water tank 8, realizing the circulation of cooling water. If the concave and convex dies are not precisely aligned, the lowering height of trigger pipe 35 is insufficient to trigger the press switch 5, and water pump 6 is not powered on and does not work. The operator can promptly identify the lateral misalignment problem between the concave and convex dies, so as to take immediate remedial measures, so that the hydraulic telescopic cylinder pulls the convex die upward to reset it, and then calibrates its position to reduce the impact of lateral misalignment of the concave and convex dies on the yield of composite material products.

[0047] This utility model is intended to cover all such substitutions, modifications, and variations that fall within the broad scope of the appended claims. Therefore, any omissions, modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
