Description

Technical Field

[0001] This utility model relates to the field of mold technology, specifically to a resin molding mold. Background Technology

[0002] Resin generally refers to an organic polymer that softens or melts when heated, tends to flow under external force when softened, and is solid or semi-solid at room temperature, and sometimes can also be liquid. In a broader sense, any polymer compound that can be used as a raw material for processing plastic products is called resin. Resin molding dies are molding tools made based on resin materials, mainly used to shape resin materials into products of a predetermined form through specific processes.

[0003] A resin molding die with publication number CN214419442U includes a base plate, with symmetrically distributed fixed seats fixedly connected to the top of the base plate. Each of the two sets of fixed seats has a rotating shaft rotatably connected to one side of each other. A support seat fixedly connected to the base plate is rotatably connected to the outer wall of the rotating shaft. In use, the output shaft of a first motor rotates, driving a stud to rotate. This rotation of the stud moves the mounting plate, which in turn moves the upper mold, causing it to abut against the lower mold for injection molding. Afterward, rotating the hook disengages it from the connecting plate, and the spring returns to its original position. The spring then moves the connecting pipe, which in turn moves the connecting plate, allowing the connecting pipe to enter the water inlet pipe. Simultaneously, the connecting plate abuts against the water inlet pipe. The water pump is then activated, drawing water from the water tank and delivering it through a hose to the connecting pipe. The water then enters the cooling chamber through the water inlet pipe and the connecting pipe, cooling the workpiece. This increases the molding speed of the workpiece, improves production efficiency, and facilitates operation.

[0004] The existing technology has the following shortcomings: During the operation of existing resin molding molds, resin residue is easily left inside the mold cavity, which cannot be easily cleaned. The residual resin will affect the quality of the next resin molding, and thus affect the efficiency of resin molding. Utility Model Content

[0005] The purpose of this invention is to provide a resin molding mold in which the top plate can push the resin molded inside the cavity upward by the operation of the first hydraulic cylinder, the rotation of the movable plate causes the push plate to rotate from the bottom of the cavity to the top of the cavity, and the operation of the two third hydraulic cylinders causes the push plate to push the resin molded on the top plate out of the mold body. At the same time, the surface of the top plate can be cleaned to solve the above-mentioned shortcomings in the technology.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a resin molding mold, comprising a mold body, and further comprising:

[0007] The ejector mechanism, located on the outer wall of one side of the mold body, is used to push the molded resin out from the inside of the mold body and clean the mold surface.

[0014] Preferably, traction plates are fixedly sleeved on the outer sides of both ends of the rotating shaft, and the inner wall of the end of the two traction plates away from the rotating shaft is rotatably connected to the outer wall of the adjacent fixed shaft.

[0015] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0016] 1. The first hydraulic cylinder operates to push the resin molded inside the cavity upwards through the top plate. At the same time, the movement of the top plate can clean the inner wall of the cavity. The servo motor drives the rotating shaft to rotate. Through the meshing action between the drive gear and the movable gear, the push plate can rotate from the bottom of the cavity to the top of the cavity. Through the extension of the two third hydraulic cylinders, the push plate can push the resin molded on the top plate out from the inside of the mold body.

[0026] This utility model provides, for example Figure 1 The resin molding die shown includes a die body 1, and further includes:

[0027] The pusher mechanism 2, located on the outer wall of one side of the mold body 1, is used to push the molded resin out from the inside of the mold body 1 and clean the mold surface.

[0028] To facilitate the ejection of the formed mold from the inside of the mold body 1 and its cleaning, such as... Figure 1-2 and Figure 4As shown, the pushing mechanism 2 includes a rotating shaft 201 disposed on one side of the outer wall of the mold body 1. A servo motor 207 is disposed at one end of the rotating shaft 201. A movable plate 202 is movably sleeved on the outer side of the rotating shaft 201. Two third hydraulic cylinders 203 are fixedly installed on one side of the outer wall of the movable plate 202. A push plate 204 is fixedly installed on the piston rod of the two third hydraulic cylinders 203. The servo motor 207 drives the rotating shaft 201 to rotate. Through the transmission of the transmission components, the movable plate 202 rotates on the outer side of the rotating shaft 201, so that the push plate 204 can rotate to the inner side of the mold body 1. Through the extension of the two third hydraulic cylinders 203, the push plate 204 can push the molded resin out from the inner side of the mold body 1. The movement of the push plate 204 can clean the inner bottom of the mold body 1.

[0029] To facilitate the removal of the molded resin from inside the cavity 102, such as Figure 1-3 As shown, the mold body 1 includes a lower mold plate 101, and a cavity 102 is formed on the inner wall of the lower mold plate 101. A first hydraulic cylinder 103 is fixedly installed at the bottom of the lower mold plate 101. A top plate 104 is fixedly installed on the piston rod of the first hydraulic cylinder 103 and located at the bottom of the inner side of the cavity 102. Guide rods 105 are fixedly installed at the four corners of the top of the lower mold plate 101. A fixing plate 106 is fixedly installed on the top of the guide rods 105. A second hydraulic cylinder 107 is fixedly installed on the top of the fixing plate 106. An upper mold plate 108 is fixedly installed at the bottom of the piston rod of the second hydraulic cylinder 107. The extension of the second hydraulic cylinder 107 causes the upper mold plate 108 to move downward along the guide rods 105. By combining the upper mold plate 108 with the lower mold plate 101, the resin can be formed inside the cavity 102. The operation of the first hydraulic cylinder 103 causes the top plate 104 to move upward along the inner wall of the cavity 102, which can push the formed resin out from inside the cavity 102 and clean the inner wall of the cavity 102 at the same time.

[0030] To facilitate the adjustment of the position of the push plate 204, such as Figure 2-4As shown, two mounting plates 109 are fixedly installed on one side of the outer wall of the lower template 101. The two mounting plates 109 are rotatably connected to both ends of the rotating shaft 201. Each mounting plate 109 has a limiting groove 110 on its inner wall. Fixed shafts 205 are fixedly installed on the outer walls of both ends of the movable plate 202. The two fixed shafts 205 are movably connected to the inner walls of the two limiting grooves 110. Movable gears 206 are rotatably sleeved on the outer sides of both fixed shafts 205. Drive gears 208 are fixedly sleeved on the outer sides of both ends of the rotating shaft 201. The two drive gears 208 are respectively connected to the two movable gears 206. 6. The rotating shaft 201 is fixedly sleeved with traction plates 209 on both outer sides. The inner wall of the end of the two traction plates 209 away from the rotating shaft 201 is rotatably connected to the outer wall of the adjacent fixed shaft 205. The servo motor 207 drives the rotating shaft 201 to rotate, causing the drive gear 208 to rotate. Through the meshing action between the gear components, the movable gear 206 rotates, which can drive the fixed shaft 205 to move along the limiting groove 110. At the same time, the traction plates 209 can pull the fixed shaft 205, so that the movable plate 202 can rotate from the vertically downward state to the vertically upward state.

[0031] During resin injection molding, the second hydraulic cylinder 107 extends, causing the upper mold plate 108 to move downward along the guide rod 105. Through the engagement of the upper mold plate 108 and the lower mold plate 101, the molten resin can be formed inside the cavity 102. Then, the first hydraulic cylinder 103 extends, causing the top plate 104 to move upward along the inner wall of the cavity 102, which can lift the formed resin upward and clean the inner wall of the cavity 102. Then, the servo motor 207 drives the rotating shaft 201 to rotate, causing the two drive gears 208 to rotate. Through the meshing action between the gears, the two movable gears 206 rotate accordingly. At the same time, the rotation of the rotating shaft 201 can drive the two traction plates 209 to rotate, so that the two fixed shafts 205 can move along the two defined... The inner wall of the groove 110 moves from the bottom to the top of the groove 110, allowing the movable plate 202 to rotate from a vertically downward position to a vertically upward position. Then, through the extension of two third hydraulic cylinders 203, the push plate 204 moves on the top surface of the lower template 101, pushing the resin formed on the surface of the top plate 104 out from the inside of the mold body 1. The movement of the push plate 204 can clean the surface of the top plate 104, ensuring its cleanliness and preventing resin residue from affecting subsequent injection molding work. This ensures the quality of the formed resin and improves the efficiency of resin molding. This embodiment specifically solves the problem in the prior art that it is not convenient to clean residual resin, which affects the quality of subsequent formed resin.

[0032] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
