Description

Technical Field

[0001] The utility model relates to the technical field of polyurethane rubber roller casting, in particular to a polyurethane rubber roller forming die. Background Technique

[0002] The polyurethane rubber roller has good chemical properties, is suitable for various types of inks and printing methods, has special resistance to the solvent components in various inks, dampening solutions and cleaning agents, and the polyurethane rubber roller is also suitable for UV ink rubber rollers and varnish rubber rollers, etc. Industrially, it is usually produced by an injection and cooling forming manufacturing mode.

[0003] The existing Chinese patent with the application number 202221874538.1 discloses a polyurethane rubber roller casting and forming die, including a die. The lower parts of the inner walls on both sides of the die are fixedly connected with fixed brackets. The upper surface of the fixed brackets is fixedly connected with sleeves. The sleeves penetrate through the fixed brackets and extend to the outside of their lower surfaces. A ejector rod is movably inserted into the sleeves. The upper end of the ejector rod is fixedly connected with an ejector block. The outer wall of the ejector block is slidably connected with the inner wall of the die. The lower parts of the inner walls on both sides of the die are rotatably connected with rotating shafts. The middle parts of the outer walls of the rotating shafts are fixedly connected with cams. The output shaft of a high-torque reduction motor drives the rotating shafts and the cams to rotate, so that during the rotation of the cams, the ejector rod is pushed upward, driving the ejector block to move synchronously, thereby pushing the cooled and formed polyurethane rubber roller in the die upward, separating it from the inner wall of the die, so as to facilitate the staff to take out the polyurethane rubber roller from the upper opening position of the die, improving the production efficiency of the polyurethane rubber roller.

[0004] However, this polyurethane rubber roller casting and forming die still has some deficiencies in actual use. For example, only the ejector block is used to push the cooled and formed polyurethane rubber roller in the die upward to separate it from the inner wall of the die. Although this is convenient for the staff to take out the polyurethane rubber roller from the upper opening position of the die, the outer wall of the cooled polyurethane rubber roller is usually adhered to the inside of the die, and the outer wall of the polyurethane rubber roller is easily damaged during the upward ejection process, and once the adhesion degree is too high, the bottom surface of the polyurethane rubber roller is easily damaged. Content of the Utility Model

[0005] The purpose of the utility model is to provide a polyurethane rubber roller forming die to solve the problems put forward in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: a polyurethane rubber roller forming die, including a frame assembly. A number of die assemblies are sequentially arranged in the frame assembly from one side to the other side. The frame assembly includes a base. Vertical grooves are formed on both side surfaces of the base. Vertical sliding plates are slidably installed in the two vertical grooves. A lifting plate is fixedly installed between the two vertical sliding plates. A linear motor is fixedly installed in the middle of the front surface of the base.

[0007] The mold assembly includes an embedding plate. Chutes are provided on both sides of the top surface of the embedding plate. Lifting slides are slidably installed in the two chutes. Semi-finished molds are fixedly installed on the top surfaces of the two lifting slides. A transmission rod is rotatably connected to the bottom surface of each of the two lifting slides. A socket rotating seat is provided between the bottom ends of the two transmission rods. The two sides of the socket rotating seat are respectively rotatably connected to one ends of the two transmission rods. A vertical rod is fixedly inserted in the middle of the socket rotating seat.

A round head is movably installed in the piston groove. The top end of the vertical rod passes through the bottom surface of the pushing chassis and extends into the piston groove. The top end of the vertical rod is fixedly connected to the bottom surface of the round head.

[0008] Preferably, a number of embedding grooves are sequentially provided on the top surface of the base from one side to the other side. The number of the embedding plates corresponds to the number of the embedding grooves one by one. The embedding plates are fixedly embedded in the embedding grooves.

[0009] Preferably, a number of the vertical rods are fixedly installed on the top surface of the lifting plate. The two semi-finished molds together form a complete polyurethane rubber roller mold.

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0021] As Figures 1-4 shown, the present utility model provides a technical solution: including a frame assembly 1, a plurality of mold assemblies 2 are sequentially arranged in the frame assembly 1 from one side to the other side. The frame assembly 1 includes a base 101. Vertical grooves 103 are opened on both side surfaces of the base 101. Vertical slide plates 104 are slidably installed in the two vertical grooves 103. A lifting plate 105 is fixedly installed between the two vertical slide plates 104. A linear motor 106 is fixedly installed in the middle of the front surface of the base 101;

[0022] The mold assembly 2 includes a fixing plate 201. Chute grooves 202 are formed on both sides of the top surface of the fixing plate 201. Lifting sliding plates 203 are slidably installed in the two chute grooves 202. Semi-finished molds 204 are fixedly installed on the top surfaces of the two lifting sliding plates 203. A transmission rod 205 is rotatably connected to the bottom surface of each of the two lifting sliding plates 203. A socket rotating seat 206 is arranged between the bottom ends of the two transmission rods 205. The two side surfaces of the socket rotating seat 206 are respectively rotatably connected to one end of the two transmission rods 205. A vertical rod 207 is fixedly inserted in the middle of the socket rotating seat 206. A pushing chassis 208 is arranged at the top end of the vertical rod 207. A piston groove 209 is formed at the center of the bottom surface of the pushing chassis 208. A round head 210 is movably installed in the piston groove 209. The top end of the vertical rod 207 passes through the bottom surface of the pushing chassis 208 and extends into the piston groove 209. The top end of the vertical rod 207 is fixedly connected to the bottom surface of the round head 210.

[0023] In this embodiment, a number of embedding grooves 102 are formed on the top surface of the base 101 in sequence from one side to the other side. The number of the fixing plates 201 corresponds to the number of the embedding grooves 102 one by one. The fixing plates 201 are fixedly embedded in the embedding grooves 102.

[0024] Meanwhile, the number of the vertical rods 207 are all fixedly installed on the top surface of the lifting plate 105. The two semi-finished molds 204 together form a complete polyurethane rubber roller mold. The back surface of the slider of the linear motor 106 is fixedly connected to the front surface of the lifting plate 105. The linear motor 106 drives the lifting plate 105 to rise. When the lifting plate 105 rises, it can drive the vertical rod 207 to rise. When the vertical rod 207 rises, it can drive the socket rotating seat 206 to rise. When the socket rotating seat 206 rises, the bottom ends of the two transmission rods 205 will rise. Since the top end of the transmission rod 205 is rotatably connected to the bottom surface of the lifting sliding plate 203, and the lifting sliding plate 203 is slidably installed in the chute groove 202, when the bottom end of the transmission rod 205 rises, the two lifting sliding plates 203 will move away from each other. When the two lifting sliding plates 203 move away from each other, they will drive the two semi-finished molds 204 to separate from each other.

[0025] Vertical rods 107 are fixedly installed at the two rear corners of the top surface of the base 101. A round shaft 108 is arranged at the top and bottom between the two vertical rods 107. Slide sleeves 211 are fixedly installed at the middle parts of the backs of the two semi-finished molds 204. The slide sleeves 211 are slidably sleeved on the round shafts 108, which can make the semi-finished molds 204 more stable during the separation and combination process.

[0026] During use, hot-melt polyurethane glue is injected into the interior of the complete forming die composed of two semi-finished forming dies 204 through the opening at the upper end. After it is formed according to the specifications of the inner wall of the forming die and cooled, the linear motor 106 is started. The linear motor 106 drives the lifting plate 105 to rise. When the lifting plate 105 rises, the vertical rod 207 can be driven to rise. When the vertical rod 207 rises, the socket rotating seat 206 can be driven to rise. When the socket rotating seat 206 rises, the bottoms of the two transmission rods 205 will rise. Since the top of the transmission rod 205 is rotatably connected to the bottom surface of the lifting slide plate 203, and the lifting slide plate 203 is slidably installed in the chute 202, when the bottoms of the transmission rods 205 rise, the two lifting slide plates 203 will move away from each other. When the two lifting slide plates 203 move away from each other, the two semi-finished forming dies 204 will be driven to separate from each other. Thus, the connection between the two semi-finished forming dies 204 and the outer wall of the formed polyurethane rubber roller can be conveniently disconnected. At the same time, when the vertical rod 207 rises, the round head 210 will be driven to rise. After the round head 210 rises and abuts against the inner top surface of the piston groove 209, the abutting chassis 208 can be driven to rise. Thus, while the connection between the two semi-finished forming dies 204 and the outer wall of the formed polyurethane rubber roller is disconnected, the formed polyurethane rubber roller can be jacked up, which is convenient for the staff to take out the polyurethane rubber roller from the forming die. This can not only effectively improve the blanking efficiency of the polyurethane rubber roller, but also avoid the situation that the polyurethane rubber roller is damaged during the ejection process.

[0027] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
