The mold demolding drive cooperates with the demolding plate to peel off the product, and each demolding plate of this scheme needs to cooperate with the demolding drive to drive the demolding, which has defects in cost and weight. In addition, in the specific implementation, for example, when used in sole molding, one demolding plate also needs two demolding drives to drive it. At this time, the synchronous cooperation of the two demolding drives needs to be considered, and the defects of cost and weight are further highlighted. Utility Model Content

[0015] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.

[0016] Reference Figure 1-4 As shown,

[0017] A two-color rubber injection molding machine mold demoulding and ejection mechanism comprises an ejection driving member 2 and an ejection plate 3 arranged on a mold 1, wherein the ejection plate 3 is located in a mold cavity of the mold 1, and the ejection driving member 2 is used to drive a push rod 4 to move telescopically, and one or more guide rods 5 are arranged on the ejection plate 3, wherein the guide rods 5 all penetrate the mold 1 and are connected to the push rod 4, and move synchronously with the extension and retraction of the push rod 4 to drive the ejection plate 3 to eject or restore.

[0018] This solution uses an ejection drive 2 to drive the push rod 4 to move telescopically, and uses the push rod 4 to move the guide rod 5. At this time, the number of guide rods 5 can be set as needed, and the telescopic movement is used to drive the ejection plate 3 to perform the ejection action, rather than directly using the ejection drive 2 for ejection, which can greatly reduce the cost and weight, and can overcome the problem of synchronous driving. The guide rod 5 moves synchronously with the push rod 4, and can simultaneously drive multiple guide rods 5 to move through the telescopic movement of the push rod 4. The driving structure is simple, the cost is low, and the synchronization effect is good.

[0019] In a preferred solution, a connecting plate 6 is fixedly connected to the push rod 4 , and the guide rod 5 is fixedly connected to the connecting plate 6 .

[0020] The connecting plate 6 is used to conveniently connect multiple guide rods 5. The push rod 4 directly drives the connecting plate 6 to move, which can synchronously drive multiple guide rods 5 to move, and then synchronously drive one or more ejection plates 3. Moreover, the connecting plate 6 can connect guide rods 5 at different positions by changing the size or shape, with a wide coverage and convenient connection.

[0021] In a further improvement, the guide rod 5 includes a sleeve 51 and a screw 52, ​​the sleeve 51 can be telescopically slid to penetrate the mold 1, and the sleeve 51 is provided with a through hole along the axial direction; the screw 52 penetrates the through hole of the connecting plate 6 and the sleeve 51 and is threadedly connected to the ejection plate 3, and the sleeve 51 is clamped by the ejection plate 3 and the connecting plate 6.

[0022] The outer sleeve 51 is mainly used as a support and can serve as a distance-fixing function. The two ends respectively support the connecting plate 6 and the ejector plate 3, and cooperate with the screw 52 to be threadedly connected with the ejector plate 3. When the screw 52 is tightened, the head of the screw 52 will press on the connecting plate 6, and the end will form a threaded connection with the ejector plate 3. After the connection is in place, the connecting plate 6 and the ejector plate 3 will be forced to be pressed against the two ends of the outer sleeve 51, thereby achieving the distance-fixing function, and the connecting plate 6 will move with the movement of the push rod 4, so the connecting plate 6 will drive the ejector plate 3 to move through the screw 52 and the outer sleeve 51 at the same time. This structure is convenient for installation and has sufficient strength.

[0023] In order to further improve the positioning effect, a groove 61 is provided on the connection plate 6 at a position corresponding to the outer sleeve 51 . The groove 61 is adapted to the shape of the outer sleeve 51 and is for the outer sleeve 51 to be embedded.

[0024] The groove 61 can prevent the outer sleeve 51 from shifting. At the same time, the groove 61 has a positioning effect on the outer sleeve 51, which can facilitate the alignment of the through hole of the outer sleeve 51 with the screw 52. This positioning effect can also maintain the smoothness of the movement between the outer sleeve 51 and the mold 1, and avoid the outer sleeve 51 being shifted by force, which causes greater friction between the outer sleeve 51 and the mold 1 when moving, affecting the movement.

[0025] In order to make the driving action more uniform, the push rod 4 is connected to the center of the connecting plate 6, and the number of the guide rods 5 is multiple and evenly distributed on both sides of the push rod 4. Under this setting, the force on the connecting plate 6 can be more uniform, and the force on the guide rods 5 can be more uniform, making the driving more stable.

[0026] It should be noted that, according to the embodiment shown in the figure, the ejector plates 3 are arranged in pairs, and the ejector drive member 2 is located between the two ejector plates 3, and each of the ejector plates 3 corresponds to two guide rods 5, so the two guide rods 5 form a group and are arranged in pairs and located on both sides of the push rod 4. By setting according to this scheme, the force can be more uniform and the driving stability can be better.

[0027] The ejection drive member 2 can be a motor, which cooperates with the push rod 4 to form an electric push rod 4 structure, or it can be a hydraulic cylinder, which cooperates with the push rod 4 to form a hydraulic push rod 4.

[0028] 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.
