However, there are two difficulties in the forming process: (1) The mold is used on a horizontal injection molding machine. Since the mold plate of the horizontal injection molding machine is far away from the worker, the worker needs to bow his body to explore into the equipment to take the product, which does not conform to the ergonomics, and it is difficult to take the product. For some products that are difficult to take, the production efficiency is low due to the excessive labor intensity; (2) The worker needs to pass through the injection molding machine to take the product, and the column of the injection molding machine is above the head of the worker. If not careful, the head of the worker will hit the column, which has a certain safety risk. In order to solve the above two problems, improve the production efficiency and reduce the safety risk, the original mold structure is improved and optimized. CONTENT OF THE UTILITY MODEL

DETAILED DESCRIPTION

[0022] The present application will be further described below in conjunction with specific examples and drawings.

[0023] Example 1

[0024] Reference Figures 1-3 As shown in the figure, an ejection mechanism 4 of a corrugated hose includes a push plate 41, an ejector rod 42, a fixed block 43, a push power assembly 44, a push plate guide column 45, and a rotary power assembly 46.

[0025] The push plate 41 moves vertically on the back mold mechanism 2, and the back mold mechanism 2 is provided with a plurality of vertical push plate guide columns 45. The push plate 41 is slidably sleeved on the push plate guide columns 45 to ensure the accuracy and stability of the vertical sliding of the push plate 41. The movement of the push plate 41 drives the vertical movement of the ejector rod 42.

[0026] The push power assembly 44 is arranged between the back mold mechanism 2 and the push plate 41. The push power assembly 44 is a pneumatic cylinder, an oil cylinder, or an electric cylinder. The push power assembly 44 provides power to finally realize the vertical lifting movement of the push plate 41.

[0027] The push plate 41 is provided with the horizontally rotating ejector rod 42 through the ejector rod bearing 423. That is, the rotation axis of the ejector rod 42 is vertical. The ejector rod 42 is fixedly connected with the fixed block 43, and the fixed block 43 is fixedly connected with the mold core 6. Therefore, when the push plate 41 vertically slides, the ejector rod 42, the fixed block 43, and the mold core 6 can be lifted together, so that the mold core 6 can be ejected from the corrugated cavity.

[0028] The rotary power assembly 46 is arranged between the push plate 41 and the ejector rod 42. The rotary power assembly 46 provides power for the rotation of the push plate 41. After the mold core 6 and the product are ejected, the rotary power assembly 46 drives the rotation of the ejector rod 42, so that the product is offset and rotated to the outside of the equipment, thereby avoiding the operation of the operator reaching into the inside of the equipment to take the product, improving the efficiency of the operation production, and reducing the safety hidden danger of the operation.

[0029] The push rod 42 is provided with a push rod slot 421, and a push rod block 422 is inserted in the push rod slot 421. The push rod block 422 is fixed on the fixing block 43. Through the structure of the block and the slot, the push rod 42 and the fixing block 43 are fixedly connected, which prevents the two from rotating relative to each other and also prevents the push rod 42 from falling off the fixing block 43.

[0030] Both sides of the push rod 42 are provided with push rod slots 421. The push rod block 422 has an L-shaped structure. One end of the push rod block 422 is locked in the push rod slot 421, and the other end of the push rod block 422 is connected to the fixing block 43 by screws. During connection, the push rod 42 is inserted into the rod groove of the fixing block 43, then the push rod slot 421 is aligned with the block slot of the fixing block 43, then the push rod block 422 is inserted into the block slot and the push rod slot 421, and finally the push rod block 422 is connected and fixed to the fixing block 43 by screws.

[0031] The rotary power assembly 46 includes a telescopic drive 461, a rack 462, an adapter 463, a first gear 464, a second gear 465, and a guide bearing 466. Similarly, the rotary power assembly 46 can also employ other forms of power capable of providing rotational torque, such as a geared motor.

[0032] The telescopic drive component 461 is fixed horizontally on the push plate 41. The telescopic drive component 461 is a cylinder, hydraulic cylinder or electric cylinder, used to provide the initial rotation power. The telescopic end of the telescopic drive component 461 is connected to the rack 462 through the adapter 463, so the telescopic drive component 461 drives the rack 462 to also perform telescopic movement.

[0033] The first gear 464 and the second gear 465 are both rotatably arranged on the push plate 41. The rotation axes of the two gears are vertical. The rack 462 meshes with the first gear 464, and the first gear 464 meshes with the second gear 465. The second gear 465 is coaxially fixed on the push rod 42. Through the conversion of gears and racks, the telescopic motion of the telescopic drive 461 is converted into the rotational motion of the push rod 42, so that the mold core 6 can be rotated and moved outside the equipment for easy removal, or the mold core 6 can be rotated and moved inside the equipment for production.

[0034] The product's rotation angle is controlled by the movement of the rack and pinion, which is achieved through two control methods. The first is the limit switch of the telescopic drive component, which is associated with equipment parameters and controls the rotation angle through parameter settings. The second is mechanical limit, which limits and blocks the movement by using the groove of the upper ejector plate and the shape of the rack and pinion.

[0035] The guide bearing 466 is rotatably arranged on the push plate 41. The rotation axis of the guide bearing 466 is vertical. The guide bearing 466 is located on the side of the telescopic path of the rack 462. The guide bearing 466 guides the smooth side of the rack 462 to make contact, thereby improving the stability of the telescopic rack 462.

[0036] The ejection mechanism 4 can also be fitted with a cover plate on the push plate 41 to shield the rotating power component 46, achieving both aesthetic appeal and protection.

[0037] Example 2

[0038] refer to Figures 1-3 As shown, a corrugated hose forming device includes a front mold mechanism, a rear mold mechanism 2, an air blowing demolding mechanism and a core pulling mechanism 5, and also includes the corrugated hose ejection mechanism 4 of Embodiment 1.

[0039] This embodiment is an optimized solution based on the invention patent application number 202210718143.0, entitled "A Forming Device and Production Method for TPV Corrugated Hose," with the difference being an improvement in the ejector mechanism 4. While that patent used two ejector rods, this application optimizes the ejector rod to a single, thicker rod to meet the rotation requirements. This application adds a locking block and a locking groove between the ejector rod and the fixing block to prevent relative rotation between them. Simultaneously, this application uses a gear and rack mechanism as the rotational power, converting the telescopic motion into rotational motion.

[0040] Other organizations use the same patent document.

[0041] This application simplifies the production process and reduces the difficulty and safety risks for workers in handling parts by modifying the ejection mechanism of the mold and adding a rotation mechanism for the mold core. The output per shift has been increased from about 100 pieces / shift to 240-260 pieces / shift (10 hours per shift).

[0042] The foregoing basic examples and their further alternative examples can be freely combined to form multiple embodiments, all of which are embodiments that can be adopted and claimed in this application. In the scheme of this application, each alternative example can be arbitrarily combined with any other basic example and alternative example.

[0043] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
