Description

Technical Field

[0001] The invention relates to a composite material molding device and a use method thereof, belonging to the field of composite material molding equipment. Background Art

[0002] In mold design, the mating surfaces of the upper and lower molds are precisely machined to ensure that they fit tightly. This fit not only helps to maintain stable pressure and temperature in the mold, but also prevents material leakage. In order to achieve a better sealing effect, mold designers usually set sealing grooves on the mating surfaces of the upper and lower molds for installing sealing elements such as O-rings, sealing rings or sealing strips. These sealing elements will be compressed when the mold is closed, forming a continuous sealing band between the upper and lower molds. This sealing band can ensure the smooth progress of the molding process.

[0003] However, the sealing belt is prone to aging when working under high temperature conditions for a long time. After aging, the sealing belt material becomes hard and its elasticity decreases, making it unable to effectively fill the gap, resulting in reduced sealing performance. After the sealing ring is aged and hardened, it is difficult to reach the normal deformation amount due to the extrusion of the upper mold, and maintenance personnel are required to check it regularly. When replacing the seal, the sealing surface also needs to be cleaned to ensure that there are no impurities or residues. The sealing groove is long and it is more difficult to clean, so improvements are made. Summary of the invention

[0004] The purpose of the present invention is to solve the above problems existing in the background technology and to provide a composite material molding device and a method of using the same.

[0005] The present invention achieves the above-mentioned purpose by adopting the following technical solutions:

[0006] A composite material molding device comprises a lower die, an upper die, a limit rod, a hydraulic cylinder and a base; the lower die is fixedly connected to the upper end of the base, and a cooling system is provided between the two; the upper end of the lower die is fixedly connected to the limit rod; the upper die is provided with a through hole that slidably cooperates with the limit rod, and the upper end of the upper die is fixedly connected to the hydraulic cylinder.

[0007] A method for using a composite material molding device, the method comprising the following steps:

[0008] Step 1: Put the raw materials for preparing the composite material into the concave mold, then start the hydraulic cylinder to make the upper mold and the lower mold fit together, and start the electric heating plate to provide heating and pressurizing conditions for preparing the composite material;

[0009] Step 2: After the preparation is completed, coolant is introduced into the cooling system from water inlet I and water inlet II to reduce the temperature.

[0010] Compared with the prior art, the beneficial effects of the present invention are as follows: the present invention only fixes the sealing ring at the upper end of the support plate II, which is convenient for disassembly of the sealing ring. At the same time, when replacing the sealing ring, it is only necessary to clean the upper end surface of the support plate II so that there is no residue, and there is no need to clean the sealing groove II. After the sealing ring of the present invention is aged, it will pop out to remind the maintenance personnel to replace it. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The technical solution of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0030] Specific implementation method 1: Figure 1-18 As shown, this embodiment records a composite material molding device, including a lower mold 1, an upper mold 2, a limit rod 3, a hydraulic cylinder 4 and a base 5; the lower mold 1 is fixedly connected to the upper end of the base 5, and a cooling system is provided between the two; the upper end of the lower mold 1 is fixedly connected to the limit rod 3; the upper mold 2 is provided with a through hole 23 that slides with the limit rod 3, and the upper end of the upper mold 2 is fixedly connected to the hydraulic cylinder 4.

[0031] A plurality of electric heating plates 52 are arranged on the upper end surface of the base 5, and a cooling system is also arranged on the upper end of the base 5, the cooling system comprising cooling slots Ⅰ51, Ⅱ53 and Ⅲ54 which are connected in sequence; the cooling slot Ⅰ51 is connected to the water inlet Ⅰ15, and the cooling slot Ⅲ54 is connected to the water outlet 13; the cooling slots Ⅱ53 and Ⅲ54 are also connected to the connecting slots 55 respectively, and the other end of the connecting slots 55 is connected to the water inlet Ⅱ14. By setting the water inlet Ⅰ15 and the water inlet Ⅱ14, the cooling slots Ⅱ53 and Ⅲ54 can be connected to the coolant solution with a lower temperature than the internal temperature thereof, thereby reducing the temperature of the mixed coolant, so as to facilitate better heat dissipation of the coolant.

[0032] The pipe diameters of the cooling groove I 51, cooling groove II 53 and cooling groove III 54 are increased in sequence. The pipe diameter is increased at the position where the coolant is introduced from the water inlet II 14.

[0033] The lower end of the upper mold 2 is provided with a sealing groove I 22 and a punch 21 .

[0034] The upper end surface of the upper mold 2 is provided with a die 11 and a sealing groove II17; the sealing groove I22 and the sealing groove II17 are both set in a square shape; the bottom surface at the corner of the sealing groove II17 is fixedly connected with an L-shaped connector 16 that slides with the sealing groove II17 through a spring I113; both ends of the connector 16 are provided with slideways, and a slider 111 is fixedly connected in each slideway through a spring II112; the slider 111 is hinged with the connecting rod 18, and the other end of the connecting rod 18 is hinged with the support plate I19; the cross-sections of the support plate I19 and the support plate II110 are both U-shaped, and the support plate II110 is embedded in the gap in the center of the support plate I19; the upper end of the support plate II110 is fixedly connected with a sealing ring 12 that cooperates with the sealing groove I22 and the sealing groove II17. The setting of the support plate II110 can reduce the difficulty of disassembling the sealing ring 12 and subsequent cleaning, avoiding wasting time. The cross section of the connecting rod 18 and the support plate Ⅰ19 at the connection position is triangular to prevent the connecting rod 18 from sticking to the side of the support plate Ⅰ19, resulting in the support plate Ⅰ19 being unable to rotate relative to the connecting rod 18.

[0035] A groove 114 is provided on the bottom wall of the sealing groove II 17 below the support plate I 19, and a telescopic limiting rod 121 is fixedly connected in the groove 114, and the free end of the limiting rod 121 is fixedly connected to the bottom surface of the support plate I 19. The limiting rod 121 limits the movement of the support plates I 19 and II 110 in the horizontal direction.

[0036] A circular hole 191 is also provided on the bottom surface of the support plate I19, and a limit block 192 is provided on the inner wall of the circular hole 191; a hole is provided on the bottom surface of the groove 114, and a rotating rod 115 is connected to the hole through a bearing; the rotating rod 115 is slidably matched with the circular hole 191; the rotating rod 115 is provided with a plurality of vertically arranged limit grooves 116 located at the top end of the outer cylindrical surface of the rotating rod 115, and a protrusion 117 is provided on both sides of the limit groove 116; a triangular groove II 120 is provided at the lower end of the protrusion 117, and a plurality of triangular grooves I 118 are provided below the triangular groove II 120, and a stopper 119 is fixedly connected to the inclined surface of the triangular groove I 118; the limit block 192 is slidably matched with the limit groove 116 and the triangular groove I 118. The moving position of the limit block 192 is limited by the triangular groove II 120, the triangular groove I 118, the protrusion 117 and the limit groove 116, so that the sealing ring 12 can be ejected after aging and hardening, so as to prompt the maintenance personnel to replace it.

[0037] One side of the protrusion 117 is provided with an inclined surface, and the horizontal distance between the inclined surface and the nearest triangular groove I 118 is equal to the length of the stop block 192. It is convenient for the stop block 192 to contact the lowest point of the triangular groove I 118 and move upward to contact the inclined surface on the side of the protrusion 117, thereby facilitating the stop block 192 to escape.

[0038] The corner of the triangular groove I 118 is located below the corresponding limiting groove 116. After the limiting block 192 enters the limiting groove 116 and moves downward, it can directly contact the corner of the triangular groove I 118 and push the rotating rod 115 to rotate through the inclined surface of the triangular groove I 118.

[0039] A method for using a composite material molding device, the method comprising the following steps:

[0040] Step 1: Put the raw material for preparing the composite material into the concave mold 11, then start the hydraulic cylinder 4 to make the upper mold 2 fit the lower mold 1, and start the electric heating plate 52 to provide heating and pressurizing conditions for preparing the composite material;

[0041] Step 2: After the preparation is completed, coolant is introduced into the cooling system from the water inlet Ⅰ15 and the water inlet Ⅱ14 to reduce the temperature.

[0042] The working principle of the present invention is: when using the device, the raw material for preparing the composite material is placed in the concave mold 11, and then the hydraulic cylinder 4 is started to make the upper mold 2 fit the lower mold 1, and the electric heating plate 52 is started to provide heating and pressurizing conditions for preparing the composite material;

[0043] When the upper mold 2 and the lower mold 1 are closed, the sealing groove Ⅰ22 of the upper mold 2 overlaps with the sealing groove Ⅱ17 of the lower mold 1, and squeezes the sealing ring 12, so that the sealing ring 12 is deformed in the horizontal direction, and the sealing groove Ⅰ22 and the sealing groove Ⅱ17 are filled. After the upper mold 2 and the lower mold 1 are closed, the connecting piece 16, the connecting rod 18, the support plate Ⅰ19 and the support plate Ⅱ110 move downward due to the squeezing of the sealing ring 12, and squeeze the spring Ⅰ113, thereby driving the limit block 192 at the lower end of the support plate Ⅰ19 to move downward, so that the limit block 192 is Fig.11 In the state shown, it moves downward until it contacts the inclined surface of the triangular groove Ⅰ118 and stops moving. After the upper mold 2 and the lower mold 1 are separated, under the elastic force of the spring Ⅰ113, the connecting member 16, the connecting rod 18, the support plate Ⅰ19 and the support plate Ⅱ110 move to the original height, and drive the limit block 192 to move upward to the position shown in FIG. Fig.11 Status shown;

[0044] When the sealing ring 12 ages, it becomes hard and its elasticity decreases. When the mold is closed, the deformation of the aged sealing ring 12 in the horizontal direction decreases and cannot completely fill the sealing groove I 22 and the sealing groove II 17. When the sealing ring 12 is pushed by the upper mold 2, the sealing ring 12 pushes the connecting piece 16, the connecting rod 18, the support plate I 19 and the support plate II 110 to move downward, and the displacement of the support plate II 110 is increased, so that the limit block 192 is pushed downward. Fig.11 In the state shown, after contacting the inclined surface of the triangular groove Ⅰ 118, it continues to move downward, and the limit block 192 pushes the rotating rod 115 to rotate through the inclined surface of the triangular groove Ⅰ 118, so that the limit block 192 moves to the corner of the lowest point of the triangular groove Ⅰ 118 ( Fig.12 As shown in the state, after the upper die 2 is separated from the lower die 1, the elastic force of the spring Ⅰ113 drives the connecting member 16, the connecting rod 18, the support plate Ⅰ19 and the support plate Ⅱ110 to move upward, and then drives the limit block 192 to move upward into the limit groove 116 through the support plate Ⅰ19, and moves to the state shown in the state shown in the state. Fig.13 In the state shown, the limit block 192 contacts the inclined surface of the protrusion 117. During the upward movement, the limit block 192 pushes the inclined surface of the protrusion 117 and drives the rotating rod 115 to rotate, so that the limit block 192 is disengaged from the limit groove 116 (i.e. Fig.14 As shown in the state, after the limit block 192 is disengaged, the slider 111 and the connecting rod 18 are pushed to move under the elastic force of the spring II 112, thereby driving the support plate I 19 and the support plate II 110 to move upward to the state shown in the state. Figure 5 In the state shown, the sealing ring 12 is lifted up so that the height of the aged sealing ring 12 is higher than that of the sealing ring 12 in the normal state, so that the maintenance personnel can find and replace it in time;

[0045] After replacing the sealing ring 12, the maintenance personnel remove the support plate II 110, and then remove the sealing ring 12 fixedly connected to the upper end of the support plate II 110, and then remove the sealing ring 12 by using a tool, and clean the upper end surface of the support plate II 110. Compared with the existing installation method of the sealing ring 12, the present invention only needs to clean the upper end surface of the support plate II 110, and the cleaning area is smaller, which is convenient for replacement;

[0046] After replacing the sealing ring 12, the sealing ring 12 is manually pushed downward, thereby driving the connecting member 16, the connecting rod 18, the support plate I 19 and the support plate II 110 to move downward, so that the limit block 192 slides into the limit groove 16. Since the corner of the highest point of the triangular groove I 118 is located below the limit groove 16, the limit block 192 will contact the inclined surface of the triangular groove I 118 during the process of sliding into the limit groove 16 and moving downward ( Fig.15 The state shown in the figure) and the rotating rod 115 is pushed to move by the inclined surface until the stop block 192 contacts the rod 119 ( Fig.16 The sealing ring 12 is then released, and the stopper 192 moves upward under the elastic force of the spring Ⅰ 113 and contacts the inclined surface of the triangular groove Ⅱ 120, pushing the rotating rod 115 to rotate along the inclined surface of the triangular groove Ⅱ 120 until the stopper 192 moves to Fig.11 In the state shown, the limit block 192 moves from the right side of the gear lever 119 to the left side of the gear lever 119 ( Fig.16 Direction under the state), then the above steps can be repeated to perform normal molding operation;

[0047] After the product is formed, coolant is introduced through water inlet Ⅰ15 and water inlet Ⅱ14 to cool it down. When the coolant introduced through water inlet Ⅰ15 flows through the connection point of cooling groove Ⅰ51, cooling groove Ⅱ53 and connecting groove 55, the coolant flowing in through water inlet Ⅱ14 is mixed here. Since the length of connecting groove 55 is shorter than the length from water inlet Ⅰ15 to the connection point of connecting groove 55 and cooling groove Ⅱ53, the temperature difference of the coolant introduced into connecting groove 55 is smaller than that of the coolant introduced from water inlet Ⅰ15 when it flows to the connection point of connecting groove 55 and cooling groove Ⅱ53, so that the temperature of the coolant introduced into connecting groove 55 is equal to that of the coolant introduced from water inlet Ⅰ15. The temperature at the connection point between the connecting groove 55 and the cooling groove II 53 is low. After the two are mixed, the temperature of the coolant in the cooling groove II 53 can be reduced, thereby enhancing the heat dissipation effect of the coolant at the position of the cooling groove II 53, and avoiding the problem of the coolant flowing into the cooling groove II 53 and causing the heat dissipation capacity to decrease due to excessive temperature; when the coolant flows to the cooling groove III 54, since the connecting groove 55 is also connected to the cooling groove III 54, the heat dissipation effect of the coolant in the cooling groove III 54 can also be guaranteed according to the above principle, avoiding the situation where the temperature of the coolant in the cooling groove III 54 is too high and the heat dissipation capacity is weakened, and finally the coolant is discharged from the water outlet 13.

[0048] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other forms of assembly without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered in all respects as exemplary and non-restrictive, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations within the meaning and range of equivalents of the claims be included in the invention.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
