[0013] Specifically, when the mold 1 and the mold 2 are butt-jointed, closed, or opened, the sliding sleeve slides on the outer wall of the guide rod to obtain sliding support.

[0014] Furthermore, a bellows is provided between the delivery pipe and the injection nozzle;

[0015] Specifically, because the injection nozzle is connected to the mold 2, it provides lateral stroke compensation when the mold 1 moves.

[0016] Further, one end of the tooth plate one is connected to the mold one, and one end of the tooth plate two is connected to the mold two;

[0017] Specifically, the tooth plate 1 and the tooth plate 2 are fixed so that when the tooth plate 1 moves, the driving force is effectively applied to the tooth plate 2 through the gear.

[0018] Furthermore, a bearing bracket is provided at the upper end of the mounting frame, and an upper end of the rotating shaft is rotatably mounted inside the bearing bracket;

[0019] Specifically, the rotating shaft 1 is supported inside the mounting frame through a bearing bracket, thereby providing stable rotation support for the gear 1.

After the mold one and the mold two are opened, relative or opposite movement is achieved through the linkage structure, and the movement is achieved through the same hydraulic rod as the driving force, thereby reducing energy consumption;

[0025] During the mold opening process, the three pairs of gears on the toothed plate are squeezed and meshed to push each other, driving the rotating shaft 2 to rotate, and the receiving plate moves to the position below the mold 1 and the mold 2. At the same time, when the mold 1 moves, the internal template is fixedly installed, and the injection part on the template automatically separates from the mold cavity, realizing automatic demoulding and receiving. The linkage between the hydraulic rod and the mechanical structure realizes automatic door opening, demoulding and receiving and transportation, which reduces manual intervention, improves production efficiency, reduces the use of electric drive equipment of the equipment, and reduces the use and maintenance costs.

[0039] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.

[0040] Example 1

[0041] See also Figure 1-Figure 4 As shown, this embodiment is a demoulding device for parts of a rubber injection molding machine.

[0042] comprising a base 101,

[0043] The injection structure 100 includes a mounting frame 108 located at the upper end of the base 101, a mold 102 and a mold 104 located inside the mounting frame 108, a delivery pipe 105 penetrating and installed inside the mounting frame 108, and an injection nozzle penetrating inside the mold 104 is arranged at one end of the delivery pipe 105, and a hydraulic rod 103 located at one side of the mounting frame 108 and having a telescopic end fixedly connected to the mold 1 102;

[0044] The mold opening structure 200 includes a rotating shaft 205 located inside the rear side of the mounting frame 108, a gear 206 fixed to the outer wall of the rotating shaft 205, and a tooth plate 203 and a tooth plate 204 located at the front and rear sides of the gear 206 and meshing with the gear 206;

[0045] The mounting frame 108 is provided with symmetrically distributed guide rods 107 inside, and the outer walls of the mold 1 102 and the mold 2 104 are both provided with symmetrically distributed sliding sleeves 106 that are slidably sleeved on the outer walls of the guide rods 107;

[0046] A bellows 201 is provided between the delivery pipe 105 and the injection nozzle;

[0047] One end of tooth plate 1 203 is connected to mold 1 102 , and one end of tooth plate 2 204 is connected to mold 2 104 ;

[0048] The upper end of the mounting frame 108 is provided with a bearing support 202, and the upper end of the rotating shaft 1 205 is rotatably mounted inside the bearing support 202;

[0049] Performing use of the injection structure 100;

[0050] The hydraulic rod 103 drives the mold 102 to move toward the center of the mounting frame 108. During the movement, the tooth plate 1 203 pushes the gear 1 206 to rotate. When the gear 1 206 rotates, it pushes the tooth plate 204 to move, so that the mold 2 104 moves toward the mold 1 102. The two opposing molds achieve relative and opposite movement through a hydraulic rod 103 and a mold opening structure 200. When the mold 1 102 and the mold 2 104 are fitted together, the delivery pipe 105 delivers the liquid material through the bellows 201 into the injection nozzle, and then into the mold cavity inside the mold 2 104 and the mold 1 102. After the rubber liquid material is cooled and formed, an injected rubber mold is formed. The relative or opposite movement of the mold 102 and the mold 2 104 is achieved by using the same hydraulic rod 103 as a driving force, thereby simplifying the driving structure of the equipment.

[0051] Example 2

[0052] See also Figure 1-Figure 4 As shown, this embodiment is based on the embodiment 1 and also includes:

[0053] as well as;

[0054] The demoulding structure 300 includes a template 303 slidably installed inside the mold 102, a top rod 302 located between the template 303 and the mounting frame 108, a bearing seat 301 located at the upper end of the base 101, a rotating shaft 306 rotatably inserted into the bearing seat 301, a linkage rod 309 sleeved on the outer wall of the rotating shaft 306, a receiving plate 308 located at the upper end of the linkage rod 309, a gear 307 sleeved on the upper end of the rotating shaft 306, and a tooth plate 305 located at the front end of the mold 1 102 and meshing with the gear 307.

[0055] The tooth plate 305 is located between the guide rods 107, the receiving plate 308 is located at the center of the mounting frame 108 and below the mold 1 102 and the mold 2 104, and the ejector rod 302 and the mold 1 102 are slidably mounted through the sealing ring 304;

[0056] Using the demoulding structure 300;

[0057] When mold 1 102 and mold 2 104 are closed, template 303 gradually enters mold 1 102 and fits with the inner wall of mold 1 102. The shape of template 303 is adapted and installed according to the injection rubber part. During the mold opening process, tooth plate 305 moves with mold 1 102, drives gear 2 307 to rotate, and then drives shaft 2 306 to rotate. Linkage rod 309 rotates with shaft 2 306, drives receiving plate 308 to gradually enter under mounting frame 108. Because ejector rod 302 is fixed on mounting frame 108, mold 1 102 slides on the outside of ejector rod 302, template 303 remains stable, and the rubber injection part on template 303 is limited by template 303.

[0058] When detaching from mold 102, the rubber injection part detaches from the mold cavity, and the receiving plate 308 receives the rubber injection part. When mold 102 and mold 2 104 are closed again for processing, gear plate 305 pushes gear 2 307 to move in the opposite direction, and receiving plate 308 rotates and moves out of mounting frame 108, so as to facilitate the removal of the rubber injection part on receiving plate 308. The hydraulic system and mechanical structure are used to accurately control the movement trajectory and speed during the mold opening process. Due to the design of automatic demoulding and receiving, power consumption can be reduced during the production process, and the risk of damage caused by incorrect operation is reduced. The automated design reduces human intervention, and less electrical equipment is used, and the use cost and maintenance cost are low.

[0059] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0060] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents.
