DETAILED DESCRIPTION

[0017] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.

[0018] Reference Figure 1-4 As shown,

[0019] A two-color rubber injection molding machine partition advance and retreat structure includes a conveyor belt 1, a connecting piece 3 arranged on the conveyor belt 1, and a partition 2 installed on the connecting piece 3. The conveyor belt 1 includes a horizontal conveying section 41 and a longitudinal conveying section 42. The horizontal conveying section 41 is located between the upper mold and the lower mold. The longitudinal conveying section 42 is connected to the horizontal conveying section 41 and is used to convey the partition 2 in the longitudinal direction; the longitudinal conveying section 42 is arranged corresponding to the mold station direction.

[0020] In this solution, the horizontal conveying section 41 is used to cooperate with the upper mold and the lower mold for molding and advancing and retreating. The horizontal section advances and retreats to allow the partition 2 to be moved out between the upper mold and the lower mold more stably, and the partition 2 is removed by the longitudinal conveying section 42, so that the upper mold and the lower mold can be reassembled and the double-layer rubber can be bonded and molded. The longitudinal conveying section 42 is located in the workstation direction of the mold, which is opposite to the direction of the injection molding machine, avoiding the partition 2 from affecting the structure of the injection molding machine and making the structure more reasonable. Moreover, the partition 2 is directly located in the direction of the workstation, which makes maintenance more convenient.

[0021] In a preferred solution, when the partition 2 is located in the horizontal conveying section 41 , it is horizontally arranged; when the partition 2 is located in the longitudinal conveying section 42 , it is longitudinally arranged.

[0022] When the longitudinal conveying section 42 is used, as shown in the figure, the partition 2 can be placed in a longitudinal setting, thereby reducing the occupied space. This is equivalent to flipping the state of the partition 2 during the conveying process, switching from a horizontal state to a numerical state, which allows users to operate more conveniently at the workstation.

[0023] In a further improvement, there is an inclined transition 43 between the horizontal conveying section 41 and the longitudinal conveying section 42.

[0024] The inclined transition 43 serves as a transition between the horizontal conveying section 41 and the longitudinal conveying section 42, which can make the state of the partition 2 more stable when flipping, and has a transition, which can make the flipping smoother.

[0025] The specific structure of the conveyor belt 1 can be set as follows:

[0026] The conveyor belt 1 also includes side plates 11 located on both sides of the partition 2. The side plates 11 are provided with grooves 13 for installing the chain 12. The grooves 13 are also provided with a transmission wheel 14 linked to the chain 12. The chain 12 and the inner wall of the groove 13 have a gap for the connector 3 to move.

[0027] The side plate 11 can be used to install multiple transmission wheels 14, and the chain 12 is installed on the transmission wheel 14 and cooperated with the transmission wheel 14, so that the chain 12 is formed with a horizontal transmission section 41 and a longitudinal transmission section 42. As shown in the figure, it can be formed into an approximately L-shaped structure, and the corner has an inclined transition 43. The groove 13 can be used to install the transmission wheel 14 and the chain 12. This cooperation method can make the chain 12 and the transmission wheel located in the side plate 11 to avoid being exposed. The connecting piece 3 is fixed on the chain 12, moves with the movement of the chain 12, and can move with the partition 2.

[0028] Preferably, connecting rods 21 are provided on both sides of the partition 2, and connecting grooves 31 for the connecting rods 21 to enter are provided at positions corresponding to the connecting rods 21 on the connecting member 3; the inner wall of the groove 13 cooperates with the chain 12 to limit the connecting rods 21 from escaping.

[0029] The inner wall of the groove 13 cooperates with the chain 12 to form a structure for limiting the connection rod 21 from escaping, so that the partition 2 can still maintain a stably connected state when it is in a flipping switching state and in a longitudinal setting. The connecting rod 21 is installed in cooperation with the connecting groove 31 of the connecting member 3, so that the partition 2 can be installed on the connecting member 3.

[0030] More specifically, in order to facilitate the rising of the lower mold and the cooperation with the upper mold, the side plate 11 is provided with a groove 15 at the position corresponding to the horizontal transmission end, and the position of the groove 15 corresponds to the connecting groove 31, so that the connecting rod 21 can enter the connecting groove 31 after passing through the groove 15.

[0031] In order to facilitate the cooperation with the upper die during the rising process, the lower die needs to move with the partition 2 during the rising process and move to the upper die for cooperation. Otherwise, the upper die and the lower die need to move toward the partition 2 to form cooperation. In the design of this scheme, the following setting can be adopted: the side plate 11 is provided with a slot 15 at a position corresponding to the horizontal transmission end, and the position of the slot 15 corresponds to the connection slot 31, so that the connection rod 21 can enter the connection slot 31 after passing through the slot 15.

[0032] The slot 15 on the side panel 11 allows the connecting rod 21 to enter or leave. When the lower mold rises, the lower mold will hit the partition 2 and move toward the upper mold with the partition 2. At this time, the connecting rod 21 leaves the connecting groove 31 and then leaves the slot 15. After injection molding, the lower mold descends to open the mold, at this time moving down with the partition 2, and as the lower mold moves down, the partition 2 will enter the connecting groove 31 through the slot 15, and be supported by the connecting piece 3 to separate from the lower mold. At this time, the partition 2 is separated and is transferred to the front of the workstation by the chain 12 for flipping and placement, which can make demolding and maintenance more convenient for the staff.

[0033] As shown in the figure, preferably, the number of the connecting rods 21 is at least four and evenly distributed on both sides of the partition 2, and the number and position of the connecting grooves 31 and the connecting members 3 correspond to the connecting rods 21. Under this setting, the connection can be more stable.

[0034] To sum up, during the implementation of this solution, the state of the partition 2 can be flipped to reduce the occupied space; and the movement of the partition 2 can avoid affecting the injection molding machine, making the setting of the injection molding machine more convenient; and the partition 2 can move together with the lower mold, and the driving method is also more convenient. The partition 2 can also cooperate with the connecting part 3 to automatically separate from the lower mold, so that the upper mold and the lower mold can re-cooperate for double-layer bonding.

[0035] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
