Description

Technical Field

[0002] Silicone molding is a common manufacturing process. During the processing, the following steps are required: 1. Mold preparation; 2. Vulcanization operation; 3. Molding; 4. Demolding. Since silicone is a flexible material, it is easy to adhere to the tooling used for pressing during the demolding process. It is not only easy to adhere to the lower tooling, but also easy to adhere to the upper tooling. However, since most of the molding techniques in the prior art use a separate tooling that goes up and down directly, there are the following problems when removing the silicone adhered to the upper layer: 1. It is inconvenient to take; 2. If the viewing angle of the upper tooling is too low, you have to bend over to observe and remove the remaining silicone material.

[0003] In order to solve the above-mentioned problems, the utility model proposes an auxiliary tooling for molding silicone products. Utility Model Content

A threaded seat 25 is provided in the middle of the lifting plate 23. A screw rod 26 is vertically screwed into the upper part of the threaded seat 25.

In order to facilitate the installation of the moving plate, see Figure 1 and 2 The movable plate 28 is inserted into the screw rod 26 and fixed to the screw rod 26 by two fixing nuts 27 on the upper and lower sides. Figure 4 In order to achieve the matching effect between the upper cover plate 31 and the movable plate 28, the movable plate 28 is set to be adjustable relative to the operating table 15. The movable plate 28 is provided with three parallel movable grooves 281, and the screw rods 26 are sleeved and installed in the movable grooves 281. The movable grooves 281 are arranged in an annular manner and are parallel to the setting direction of the linkage shaft 312.

It should be noted that a plurality of screw installation grooves matching the screw rods 26 should be set on the threaded seat 25;

[0034] A positioning step 29 is provided on one side of the movable plate 28 facing the pressing assembly 3, and a limiting groove 291 is provided on the positioning step 29;

[0035] In addition, in the above situation, the screw hole diameter of the screw 26 can be set to be small in the upper section and large in the lower section, and the two matching fixing nuts 27 also have different hole diameters, which is convenient for positioning at the transition position to achieve a limiting effect;

[0037] See Figure 3 In order to achieve a smoother molding feeding operation of moving the upper cover plate 31 and the lower base plate 32, a slider 321 is provided under the lower base plate 32, and the slider 321 is embedded in the sliding groove 151 to slide. At the same time, a sliding groove 151 for sliding of the pressing component 3 is also provided on the corresponding operating table 15.

[0038] In specific use, the working principle of this device is:

[0039] Before molding, the lifting plate is first lifted by the hydraulic cylinder, and the lifting plate lifts the threaded seat synchronously, and the threaded seat drives the screw and the movable plate to lift. The lifting of the movable plate can lift the upper cover plate through the linkage shaft, and then fill the lower cover plate with silicone product. At this time, it is not necessary to reach the height of the connecting rod during the lifting process, so there will be no flipping effect. Then the hydraulic cylinder is used in reverse to drive the upper cover plate to press the lower base plate. After the pressing is completed, the pressing assembly is pulled backward by the pulling device connected to the lower base plate into the molding mechanism, and the molding mechanism is used for molding. It should be noted here that the molding mechanism and the pulling device are both existing technologies, and the main innovation of this device lies in the tooling part, so the existing part will not be described in detail. After the molding is completed, the pulling device pushes the pressing assembly forward again, restores it to its original position, and then the hydraulic cylinder is used to press it again The lifting plate, threaded seat and movable plate are lifted. Since a limiting groove is provided on the positioning step at the edge of the movable plate, the limiting groove can cooperate with the linkage shaft to cooperate with the linkage shaft and lift it during the lifting process (when the linkage shaft moves back and forth, there will be no interference due to misalignment). When lifted to a certain range of heights, the upper cover plate is still in a parallel state with the lower base plate. When the lifting exceeds a certain height, since a pressure block is provided at the rear end of the upper cover plate, the pressure block is pressed on the pressure roller, and the pressure roller drives the front side of the upper cover plate to tilt up. At the same time, since the linkage shaft at the edge of the upper cover plate is limited in the limiting groove, only the front end will flip over, and due to the cooperation of the limiting strip and the groove, the effect of effective limiting in the flipping process can be achieved. After the flipping is realized, the mold cavity on the inner side of the upper cover plate and the mold cavity of the lower cover plate can be directly processed manually, which reduces the complexity of the operation and is more convenient to use.
