Description

Technical Field

[0001] The utility model relates to the technical field of latex pillow production, in particular to a die pressing device for latex pillow production. Background Art

[0002] Latex pillows are made of pure natural latex, which is more elastic and breathable than traditional pillows. Latex pillows are made of natural latex using high-tech methods. During the production of some latex pillows, the latex is injected into the mold by a glue injection machine, and then the mold is tightened to form foam.

[0003] However, the molds used in the production of existing latex pillows are mostly hinged on one side and pressed on the other side. The pressing pressure on one side is uneven, which affects the balance of the mold. The hinge serves as an auxiliary structure during pressing. After long-term use, the hinged side is prone to loosening, which reduces the service life of the hinge and affects the sealing of the mold. In order to address the deficiencies of the prior art, we propose a compression molding device for latex pillow production. Utility Model Content

[0012] Beneficial Effects

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] 1. In the utility model, the waist-shaped hole is provided to expand the range of movement of the bending shaft at the connecting plate. When the sealing cover plate is pressed, the bending shaft is not subjected to stress as a necessary structure like the traditional hinged structure. The bending shaft and the connecting assembly are effectively protected, and the service life is extended, thereby extending the overall life of the equipment. The limiting semi-ring in the connecting assembly drives the rubber pad to be pressed under the tension of the elastic rope to limit the rotation range of the bending shaft in the waist-shaped hole, preventing the sealing cover plate from being opened too quickly and hitting the main body of the die pressing device, providing auxiliary limiting force for the operator, and making it more convenient for the operator to operate.

The worker grasps the crank handle to drive the rocker to rotate the screw, and the screw drives the pressing piece on the pressure plate to press the sealing cover plate. The rocker handle is used as an auxiliary tool for tightening the screw, which saves the worker's effort when operating. At the same time, the sealing cover plate is tightly pressed against the main body of the die pressing device by using the symmetrical clamping components on both sides. The clamping force on both sides of the sealing cover plate and the main body of the die pressing device is more uniform. Compared with unilateral clamping, the main body of the die pressing device is more balanced in force, has better sealing, and improves the product yield rate. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] like Figure 1-Figure 4 As shown, it includes a die pressing device body 1, a built-in cavity 2 is provided on the top of the die pressing device body 1, two connecting components 4 are symmetrically arranged on one side of the die pressing device body 1, and the connecting component 4 includes a connecting plate 18, one side of the connecting plate 18 is fixedly connected to one side of the die pressing device body 1, a waist-shaped hole 19 is provided on one side of the connecting plate 18, a sliding groove is provided inside the waist-shaped hole 19, an elastic rope 20 is fixedly installed at the bottom of the inner wall of the sliding groove provided by the waist-shaped hole 19, and a limited position semi-ring 21 is slidably connected inside the sliding groove provided by the waist-shaped hole 19, and the die pressing device body 1 is symmetrically opened on the top. Two positioning holes 5 are provided, and positioning pins 6 are slidably connected inside the positioning holes 5. A sealing cover plate 7 is fixedly installed on the top of the positioning pin 6. A bending shaft 8 is symmetrically installed on one side of the sealing cover plate 7. When the sealing cover plate 7 is pressed, the bending shaft 8 does not bear force as a necessary structure like a traditional hinged structure. The bending shaft and the connecting components are protected and the service life is extended. A handle 9 is fixedly installed on the top of the sealing cover plate 7. Workers can quickly and accurately align the positioning pins 6 at the bottom of the sealing cover plate 7 with the positioning holes 5 on the main body 1 of the die pressing device, which makes it more convenient for workers to operate.

[0023] To carry out the preparation work before production, the worker injects latex into the built-in cavity 2 opened on the main body 1 of the die pressing device, pulls the handle 9 to drive the sealing cover plate 7, and the sealing cover plate 7 drives the bending shaft 8 to slide in the waist-shaped hole 19 opened in the connecting plate 18. The connecting plate 18 cooperates with the waist-shaped hole 19 to limit the movable range of the bending shaft 8 to control the sealing cover plate 7. When the bending shaft 8 rotates in the waist-shaped hole 19, the elastic rope 20 fixedly installed in the slide groove opened in the waist-shaped hole 19 pulls the limiting semi-ring 21 by its own elastic force to drive the rubber pad 22 to press onto the bending shaft 8, thereby increasing the friction force of the bending shaft 8 in the waist-shaped hole 19, making it more convenient to control the position of the bending shaft 8 in the waist-shaped hole 19, preventing the worker from opening the sealing cover plate 7 too quickly and hitting the main body 1 of the die pressing device, providing auxiliary limiting force for the operating worker, and making it more convenient for the worker to operate.

[0024] like Figure 2 and Figure 3 As shown, clamping assemblies 3 are provided on both sides of the main body 1 of the die pressing device, and the clamping assembly 3 includes a mounting plate 12, one side of the mounting plate 12 is fixedly connected to one side of the main body 1 of the die pressing device, a pressing plate 13 is rotatably connected to the top of the mounting plate 12, a threaded hole is provided at one end of the pressing plate 13 away from the mounting plate 12, a screw rod 14 is threadedly connected in the threaded hole of the pressing plate 13, a pressing plate 15 is fixedly connected to the bottom end of the screw rod 14, a rocker 16 is fixedly installed on the top end of the screw 14, and a rocker 17 is rotatably connected to the top of the rocker 16.

[0025] In order to evenly compress the sealing cover plate 7, a second rounded corner is provided at the end of the crank handle 17 away from the rocking wheel 16. The height of the screw 14 is twice the height of the pressure plate 13, and the diameter of the pressing piece 15 is three times the diameter of the screw 14, so as to increase the pressure surface of the screw 14 on the sealing cover plate 7. The pressing piece 15 has the same diameter as the rocking wheel 16. The worker grasps the crank handle 17 to drive the rocking wheel 16 to rotate the screw 14. The screw 14 drives the pressing piece 15 on the pressure plate 13 to press the sealing cover plate 7. The rocking wheel 16 and the crank handle 17 serve as auxiliary tools for tightening the screw 14. The auxiliary tool can save workers' effort when operating. The sealing cover plate 7 is symmetrically pressed tightly on the die device body 1 on both sides. Compared with unilateral pressing, the die device body 1 is more balanced in force and has better sealing, which improves the product yield rate. When the sealing cover plate 7 is pressed on the die device body 1, the connection between the bent shaft 8 and the connecting plate 18 is not a necessary pressing structure. Compared with the traditional hinged structure, the sealing cover plate is pressed as a necessary structure, which effectively protects the bent shaft 8 and the connecting plate 18 and prolongs the service life.

[0026] How it works

[0027] It should be noted that the utility model is a die pressing device for latex pillow production. When in use, the worker first injects latex into the built-in cavity 2 opened on the main body 1 of the die pressing device, and then pulls the handle 9, which drives the sealing cover plate 7 to drive the bending shaft 8 to move, and the bending shaft 8 slides in the waist-shaped hole 19 opened in the connecting plate 18. Therefore, the connecting plate 18 cooperates with the waist-shaped hole 19 to limit the range of motion of the bending shaft 8, thereby controlling the range of motion of the sealing cover plate 7. The connecting plate 18 cooperates with the bending shaft 8 to form a rotating shaft. When the bending shaft 8 is in the waist-shaped hole 19, the elastic rope 20 fixedly installed in the slide groove opened in the waist-shaped hole 19 pulls the limiting semi-ring 21 by its own elastic force to drive the rubber pad 22 to press on the bending shaft 8, thereby increasing the friction force of the bending shaft 8 in the waist-shaped hole 19, making it more convenient to control the position of the bending shaft 8 in the waist-shaped hole 19, and the sealing cover plate 7 and the main body 1 of the die pressing device are connected as a whole through the bending shaft 8 cooperating with the connecting plate 18;

[0028] Next, align the positioning pin 6 at the bottom of the sealing cover plate 7 with the positioning hole 5 on the die pressing device body 1, locate the sealing cover plate 7 on the die pressing device body 1, cover the sealing cover plate 7 on the die pressing device body 1, push the pressing plates 13 on both sides of the die pressing device body 1 to rotate on the mounting plate 12, place the pressing plate 13 horizontally on the sealing cover plate 7, grab the pressing plate 13, shake the handle 17 to drive the rocker 16 to drive the screw 14, and rotate the screw 14 in the threaded hole on the pressing plate 13, so that the screw The rod 14 drives the pressing plate 15 to rotate until the bottom of the pressing plate 15 presses against the upper surface of the sealing cover plate 7, and then the handle 17 is continuously shaken. The pressing plate 15 presses against the sealing cover plate 7 and presses the sealing cover plate 7 tightly under the action of the screw 14. The sealing cover plate 7 is symmetrically pressed tightly against the main body 1 of the die pressing device on both sides, so as to achieve the purpose of improving the sealing by pressing on both sides. When the sealing cover plate 7 is pressed against the main body 1 of the die pressing device, no pressure is applied to the connection formed by the bending shaft 8 and the connecting plate 18, so as to achieve the purpose of protecting the connection.
