Description

Technical Field

[0001] This application relates to the field of secondary foaming technology, and particularly to a secondary foaming hydraulic device. Background Art

[0002] In industry, secondary foaming generally refers to a foaming process in which polymers or other materials are cross-linked under high temperature and high pressure conditions, the blowing agent decomposes to generate gas and pre-foams, and then further foaming and molding is carried out under lower pressure or conditions. This process can be divided into two stages, each stage involving a foaming process, so it is called secondary foaming.

[0003] Before secondary foaming, if the mold temperature is too high, it may affect the foaming effect of the EVA material, such as causing uneven or too fast foaming, thus affecting the product quality. Therefore, the hydraulic foaming machine needs to cool down and clean the mold before secondary foaming to ensure the smooth progress of the foaming process and the stability of product quality. Currently, the cooling of the mold is mainly achieved by spraying water mist on the mold surface to help adjust the mold temperature to an appropriate range. The water mist spraying is usually carried out by manually holding a water mist spraying device to spray and cool the mold. Since the secondary foaming hydraulic device usually has multiple layers of molds, the method of manually spraying water mist layer by layer has low efficiency and affects the production efficiency of the entire device.

[0030] The following combines the attachedFigures 1-3 A further detailed description of the present application will be given.

[0031] An embodiment of the present application discloses a secondary foaming oil pressure device. As Figure 1 and Figure 2 , the secondary foaming oil pressure device includes a movable frame 1, which is made of a strong metal material to ensure sufficient load-bearing capacity and stability. Four universal wheels 12 are installed at the bottom of the frame 1, and these universal wheels 12 allow the device to move flexibly in the workshop to adapt to different working positions. In order to prevent the universal wheels 12 from flipping unnecessarily during the movement towards the oil pressure device, a guide groove 13 is also provided on one side of the device, and the design of the guide groove 13 can limit the movement range of the universal wheels 12 and increase the stability of the frame 1 during movement.

[0032] As Figure 2 and Figure 3 , on the frame 1, according to different preset mold heights, a plurality of vertically sliding lifting seats 14 are provided, and a control component 3 for driving the vertical movement of the lifting seats 14 is provided on the frame 1. The lifting seats 14 are connected to the frame 1 through slide rails 31, and the slide rails 31 are fixed on both sides of the frame 1 to ensure that the lifting seats 14 can move up and down smoothly. A support arm 2 is fixedly connected to each lifting seat 14, and the support arm 2 is used to support, fix and guide the pipeline 21.

[0033] The pipeline 21 extends along the support arm 2 and a nozzle 22 is provided at the end. The other end of the pipeline 21 is connected to a pump set 23 provided on the frame 1, and the pump set 23 is connected to a water tank.

[0034] The control component 3 mainly includes slide rails 31, which are fixed on the frame 1. Two sliders 32 are slidably arranged on the slide rails 31. A connecting rod 33 is hinged to each of the two sliders 32, and the other end of the connecting rod 33 is hinged to the corresponding lifting seat 14. The two connecting rods 33 corresponding to the same slide rail 31 have opposite inclination directions. The slide rail 31 is rotatably connected to a stud 34, and the axial direction of the stud 34 is parallel to the axial direction of the slide rail 31. The stud 34 passes through the two sliders 32 and is threadedly connected to the two sliders 32. The stud 34 is a bidirectional screw, and the thread segments of the bidirectional screw corresponding to the two sliders 32 have opposite thread directions. The operator can drive the two sliders 32 to approach or move away from each other by rotating the bidirectional screw. When the bidirectional screw rotates, due to the action of the thread, the two sliders 32 will approach or move away from each other along the slide rail 31 at the same time, and under the linkage action of the connecting rod 33, the lifting seat 14 is driven to move up and down.

[0035] In addition, to further increase the flexibility of the support arm 2, the support arm 2 is designed to be hinged to the lifting seat 14. A sleeve 4 is also hinged to the lifting seat 14. An inner rod 41 is slidably inserted into the sleeve 4. External threads are provided on the inner rod 41. One end of the sleeve 4 away from the hinge point is rotatably connected to a nut 42. The nut 42 is sleeved on the inner rod 41 and forms a threaded connection with the inner rod 41. By rotating the nut 42, the inner rod 41 can be driven to move up and down in the sleeve 4, thereby driving the support arm 2 to achieve fine angle adjustment to ensure that the nozzle 22 can accurately align with a specific position of the mold.

[0036] A push handle 5 is further provided on the frame 1. A button 51 for controlling the opening and closing of the pump group 23 is installed on the push handle 5. The operator moves the device to a designated position, and the nozzle 22 can be controlled to spray water through the button 51.

[0037] In summary, the secondary foaming hydraulic device of the present invention realizes the water spraying and cooling effect on molds of different heights through the movable frame 1, the support arm 2 with a lifting function, and the precise pipeline 21 and nozzle 22 system. Compared with the operator manually spraying water on each layer of molds individually, the device in this application is more conducive to improving the efficiency of water mist spraying and cooling, and thus improving the production efficiency of the entire device.
