[0022] The utility model provides a tooth-shaped forming mold for a headrest tube of an automobile seat, comprising a workbench 101, a die pressing mechanism 102, a lower mold 103 and a demoulding assembly, wherein the demoulding assembly comprises a base 104, a motor 105, a first rotating shaft 106, two groups of elastic members and two groups of telescopic members, each group of the elastic members comprises a support seat 107, a second rotating shaft 108, a transmission belt 109, a turntable 110, three dampers 111 and three knocking balls 112, and the telescopic member comprises an extension rod 113, a sleeve 114, a spring 115, a telescopic rod 116 and an arc plate 117. The above-mentioned scheme solves the problem that the headrest tube material is not easy to demould after the die pressing is completed, and the direct removal may cause the surface of the headrest tube material to be damaged.

[0023] According to the present specific embodiment, the die pressing mechanism 102 is fixedly connected to the workbench 101 and is located above the workbench 101. The lower mold 103 is fixedly connected to the workbench 101 and is located below the die pressing mechanism 102. The lower mold 103 has a through slot 119. The demoulding assembly includes a base 104, a motor 105, a rotating shaft 106, two groups of elastic members and two groups of telescopic members. The base 104 is fixedly connected to the workbench 101 and is located in the cavity 118. The motor 105 is fixedly connected to the base 104 and is located above the base 104. The rotating shaft 106 is fixedly connected to the output end of the motor 105 and is located on the outside of the motor 105. The two groups of elastic members are symmetrical. The elastic member is rotatably connected to the motor 105 and is located in the cavity 118. The two groups of telescopic members are symmetrically arranged. The telescopic member is slidably connected to the lower mold 103 and is located in the through groove 119. The telescopic member passes through the workbench 101. The headrest tube is placed on the lower mold 103. The molding mechanism 102 molds it. After the molding is completed, the headrest tube is pushed upward and demolded by the telescopic member. If it is stuck in the lower mold 103, the base 104 fixes the motor 105, and the motor 105 drives the rotating shaft 106 to rotate. The elastic member elastically knocks the telescopic member to generate vibration, so that the headrest tube is demolded. This method can effectively solve the problem that the headrest tube material is not convenient to demold after the molding is completed.

[0024] Among them, the support seat 107 is fixedly connected to the workbench 101 and is located in the cavity 118. The second rotating shaft 108 is rotatably connected to the support seat 107 and is located on the outside of the support seat 107. The transmission belt 109 is sleeved on the surfaces of the first rotating shaft 106 and the second rotating shaft 108. The support seat 107 supports the second rotating shaft 108, and the transmission belt 109 drives the second rotating shaft 108 to rotate synchronously with the first rotating shaft 106.

[0025] Secondly, the turntable 110 is fixedly connected to the second rotating shaft 108 and is located on the outside of the second rotating shaft 108. The damper 111 is fixedly connected to the turntable 110 and is located on the outside of the turntable 110. The knocking ball 112 is fixedly connected to the damper 111 and is located above the damper 111. The three dampers 111 and the three knocking balls 112 are distributed circumferentially along the axial center line of the turntable 110. When the turntable 110 rotates, the damper 111 drives the knocking ball 112 to rotate.

[0026] At the same time, one end of the extension rod 113 is detachably connected to the knocking ball 112 and is located above the knocking ball 112, and the extension rod 113 passes through the workbench 101, and the sleeve 114 is fixedly connected to the other end of the extension rod 113 and is located in the through groove 119, and the spring 115 is arranged on the outside of the sleeve 114, and the knocking ball 112 knocks the extension rod 113 to cause the sleeve 114 to vibrate, and the spring 115 can demold the headrest tube that has been molded. Demolding it by the spring 115 can effectively prevent the surface of the headrest tube from being damaged due to excessive pushing force. When the spring 115 cannot be demolded, the vibration generated by the sleeve 114 is used to assist in demolding.

[0027] In addition, the telescopic part also includes a telescopic rod 116 and an arc plate 117. The telescopic rod 116 is slidably connected to the sleeve 114 and is located above the sleeve 114. The arc plate 117 is fixedly connected to the telescopic rod 116 and is located above the telescopic rod 116. When the molding mechanism 102 is in operation, it presses the headrest tube downward, pushes the arc plate 117 to move downward, and the telescopic rod 116 is pressed downward in the sleeve 114.

[0028] The toothed forming mold of the headrest tube of the automobile seat of the present embodiment is used, by setting a die pressing mechanism 102, a lower mold 103 and a demoulding assembly. When it is used, the headrest tube is placed on the lower mold 103, the die pressing mechanism 102 is pressed down to mold it, and at the same time, the arc plate 117 is pressed down, the telescopic rod 116 is pressed down in the sleeve 114, and the spring 115 is compressed. After the die pressing is completed, the headrest tube is demoulded by the spring 115. If it cannot be disengaged, The motor 105 drives the rotating shaft 106 to rotate, the transmission belt 109 drives the rotating shaft 2 108 to rotate synchronously with the rotating shaft 106, the turntable 110 rotates, and the damper 111 drives the knocking ball 112 to rotate. The knocking ball 112 knocks the extension rod 113 to vibrate its sleeve 114, and the headrest tube is demolded by vibration, thereby effectively solving the problem that the headrest tube material is difficult to demold after the molding is completed and forced removal will cause surface damage.
