Description

Technical Field

[0001] The invention relates to the technical field of sole production, in particular to a rapid injection molding device for a rubber sole. Background Art

[0002] At present, the production of rubber soles usually adopts injection molding of a single material, and most of the equipment is a fixed mold, which cannot meet the needs of multi-material composite. In the traditional process, if it is necessary to make a multi-layer sole with different physical properties, it is often necessary to perform injection molding in multiple times or complete it through subsequent bonding and assembly. This not only increases production time and cost, but may also lead to poor interlayer bonding and affect product quality. In addition, traditional injection molding equipment mainly relies on pressure when filling materials, which is prone to problems such as uneven material distribution, bubbles and inconsistent thickness, resulting in reduced product quality. The unloading process usually requires manual operation, which is inefficient and easy to damage the product during demolding. The drive system lacks an effective protection mechanism, and the equipment is prone to overload under high load, resulting in mechanical failure and production stagnation. These problems limit the efficiency of rubber sole production and the diversity of products. There is an urgent need for a new injection molding device that can improve production efficiency, realize multi-material one-piece molding, has a high degree of automation and has equipment protection functions.

[0022] Each forming block 123 is provided with an exhaust port 125 connected to the forming die 124; each unloading forming baffle 128 is rotatably mounted on the corresponding unloading support rotating frame 137, each unloading support rotating frame 137 is fixed on two parallel unloading support slide bars 135, and the unloading support slide bars 135 are slidably set on the corresponding sliding T-shaped frame 130, and the sliding T-shaped frame 130 is fixed to the forming block 123 through an extension arm 129, and the outer surface of each unloading support slide bar 135 is surrounded by a unloading support return spring 136, and the two ends of the unloading support return spring 136 are fixed to the unloading support rotating frame 137 and the sliding T-shaped frame 130.

A passive magnetic plate 132 is fixed to one end of the two locking guide slide bars 133 away from the locking sliding push plate 138. The passive magnetic plate 132 and the electromagnet 131 cooperate with each other by magnetic force.

[0023] The working principle of a rubber sole rapid injection molding device disclosed in the present invention is as follows: rubber melts of different materials are respectively injected into the first rotating connecting nozzle 116, the second rotating connecting nozzle 117 and the third connecting extension tube 118 (heating wires are arranged on the flow path from the first rotating connecting nozzle 116, the second rotating connecting nozzle 117, the second multi-way pipe 119 to the molding die 124 to prevent the rubber melt from solidifying midway), and the rubber melt will flow into the corresponding third multi-way pipe 121, the first multi-way pipe 120 and the second multi-way pipe 119 through the corresponding first connecting vertical pipe 140, the second connecting vertical pipe 139 and the third connecting extension pipe 118. The driving motor 112 is started, and the output shaft of the driving motor 112 drives the active synchronous impeller 111 to rotate, and the active synchronous impeller 111 drives the fluid medium inside the regulating chamber 103 to move, and then the flowing fluid medium drives the passive synchronous impeller 109 to rotate, and the passive synchronous impeller 109 drives the transmission shaft 108 to rotate (the output shaft of the driving motor 112 and the transmission shaft 108 are both in rotation with the regulating chamber 103 The seal cooperates), the transmission shaft 108 drives the bottom support plate 107 to rotate, and the bottom support plate 107 drives the forming The block 123 rotates, and the molding block 123 drives the extended support arm 126 to rotate, so that the rubber melt inside the injection channel tube 127 in the extended support arm 126 flows into the molding die 124. Specifically, it is necessary to control the blocking state of the rubber melt flowing into the first rotating connecting nozzle 116, the second rotating connecting nozzle 117 and the third connecting extension tube 118 (if the corresponding first rotating connecting nozzle 116, the second rotating connecting nozzle 117 and the third connecting extension tube 118 are blocked, the internal rubber melt will no longer flow). The rubber melt can be input into the first rotating connecting nozzle 116 or the second rotating connecting nozzle 117 or the third connecting extension tube 118, and the corresponding injection channel tube 127 can then be poured into the molding die 124. The rubber melt in the rotating state and entering the molding die 124 will be spread on the side of the discharge molding baffle 128 under the action of centrifugal force, forming a rubber layer of uniform thickness on the surface of the discharge molding baffle 128 (at the same time, the action of centrifugal force can also eliminate the bubbles inside the rubber). Similarly, rubbers of different materials can be poured into the molding die 124 in sequence through different injection channel tubes 127, so as to realize a multi-layer rubber sole (injecting multiple rubber materials can give different physical properties to different areas of the sole during the one-piece molding process, such as wear-resistant areas and shock-absorbing areas). It should be noted that if the density of the rubber material on the side away from the discharge molding baffle 128 is greater than the density of the rubber material on the side close to the discharge molding baffle 128, it is necessary to wait for the rubber on the side close to the discharge molding baffle 128 to cool slightly before pouring the next layer of rubber.

[0024] When unloading, it is only necessary to control the electromagnet 131 to be powered off, and then the electromagnet 131 and the passive magnetic plate 132 are separated from the magnetic attraction. At this time, under the action of centrifugal force, the unloading forming baffle 128 is separated from the forming block 123. This process will cause the unloading support slide bar 135 to slide with the sliding T-shaped frame 130, the unloading support return spring 136 to be compressed, the locking guide slide bar 133 to slide with the sliding T-shaped frame 130, the locking return spring 134 to be compressed, and at the same time, since the top end of the unloading forming baffle 128 is rotationally connected to the unloading support rotating frame 137, the unloading forming baffle 128 will rotate relative to the unloading support rotating frame 137 under the centrifugal force. The bottom of the molding baffle 128 will swing outward, thereby squeezing the locking sliding push plate 138, and then the cooled and shaped sole will be separated from the molding die 124 or the unloading molding baffle 128 under the action of centrifugal force, reducing the rotation speed of the molding block 123, so that the unloading molding baffle 128 is reset under the joint elastic force of the unloading support reset spring 136 and the locking reset spring 134, and re-contacts with the molding block 123, so that the molding die 124 is closed, and then the electromagnet 131 is started, and the electromagnet 131 attracts the passive magnetic plate 132, so that the unloading molding baffle 128 cannot move, thereby achieving the locking of the unloading molding baffle 128, and now the next batch of soles can be injection molded.

[0025] In the default state, the fluid medium inside the regulating chamber 103 is at room temperature. When the transmission torque from the drive motor 112 to the forming block 123 needs to be increased, it is only necessary to control the start of the refrigeration secondary plate 102. The refrigeration surface of the refrigeration secondary plate 102 will reduce the temperature of the regulating chamber 103, thereby reducing the temperature of the inner heat conduction plate 142, and then reducing the temperature of the internal fluid medium. At this time, the density of the fluid medium will increase, thereby increasing the force driven by the passive synchronous impeller 109 by the fluid medium, and then increasing the force on the rotation of the forming block 123. This process will also drive the heat dissipation fan 106 to rotate, and the rotation of the heat dissipation fan 106 will drive air to blow toward the heat dissipation outer shell 101. Since the heat dissipation outer shell 101 is in contact with the heating surface of the refrigeration secondary plate 102, it is necessary to dissipate heat from the heat dissipation outer shell 101. On the contrary, when the heating wire inside the heating plate 110 is activated, the fluid medium inside the regulating chamber 103 will be heated, thereby reducing the density of the fluid medium (in this process, the floating piston 105 will slide in the redundant chamber 104), and the power generated by the fluid blowing toward the passive synchronous impeller 109 will be weakened, thereby reducing the force on the rotation of the forming block 123. Therefore, by adjusting the rotation force of the forming block 123, the drive motor 112 can be prevented from being damaged due to overload when the rotation of the forming block 123 is blocked.
