In this embodiment, by arranging two sets of mold opening mechanisms 3, the stability of the opening of a single polyurethane elastomer pad forming mold 4 can be improved, and the efficiency of the opening of adjacent two polyurethane elastomer pad forming molds 4 can be improved.

[0073] In one embodiment, the mold opening member 33 is a double-shaft mechanism, for example, a double-shaft cylinder or a double-shaft hydraulic cylinder, and a double-shaft hydraulic cylinder is preferably used, which can provide the opening force of the polyurethane elastomer pad forming mold 4.

[0074] In one embodiment, the guide rail 11 is provided with a roller groove 111, and the lug plate 42 is provided with a roller 423 that rolls with the roller groove 111, further reducing the moving resistance of the mold plate 41 and the lug plate 42 on the guide rail 11. Preferably, the mold pressing plate 21 arranged on the guide rail 11 can also be provided with a roller that matches the roller groove 111, reducing the friction resistance between the mold pressing plate 21 and the guide rail 11, and further reducing the burden of the linear movement driving mechanism 122.

[0075] In one embodiment, one of the mold pressing plates 21 is fixedly arranged on the two guide rails 11, and the other mold pressing plate 21 is driven by the linear movement driving mechanism 122 to move linearly and reciprocally along the guide rail 11. In this embodiment, all polyurethane elastomer pad forming molds 4 can be based on the fixed mold pressing plate 21, which facilitates the accurate determination of the positions of the polyurethane elastomer pad forming molds 4 by the mold opening mechanism 3.

[0076] In one embodiment, the mold plate 41 and the lug plate 42 are detachably matched. In this embodiment, the existing different types of mold plates 41 can be equipped with lug plates 42, and then the polyurethane elastomer pad forming device is adapted.

[0077] In one of the embodiments, two of the guide rails 11 are below the discharge port; the product is discharged from the discharge port after the polyurethane elastomer pad forming mold 4 is split, preferably, a product collecting device or a product conveying device, such as a collecting box or a conveying belt, is arranged at the discharge port, and after the product is discharged, the next pouring process can be carried out. Preferably, the support 1 further comprises a frame 12 for supporting the guide rails 11, and the linear movement driving mechanism II 31 is arranged on the frame 12.

[0078] In one of the embodiments, a mechanical hand mechanism 5 and a mold bank 6 are further included, the mechanical hand mechanism 5 is used to transfer the polyurethane elastomer pad forming mold 4 between the mold bank 6 and the guide rails 11. In this embodiment, various types of polyurethane elastomer pad forming molds 4 are stored in the mold bank 6, and the mechanical hand mechanism 5 can automatically grab the polyurethane elastomer pad forming mold 4 through a program and place it on the support 1 or back to the corresponding position of the mold bank 6.

[0079] In one of the embodiments, the exhaust hole 415 of the middle polyurethane elastomer pad forming mold 4 is smaller in diameter than the exhaust hole 415 of the outer polyurethane elastomer pad forming mold 4, which prevents the middle polyurethane elastomer pad forming mold 4 from being filled with the pouring material that has overflowed from the exhaust hole 415, and the outer polyurethane elastomer pad forming mold 4 from being not filled with the pouring material, resulting in product defects such as material shortage, bubbles, and deformation.

[0080] In one of the embodiments, referring to the accompanying drawings Figure 17 - the accompanying drawings Figure 19 , the polyurethane elastomer pad forming mold 4 further comprises an insert 418 with an exhaust hole 415, at this time, a fitting groove III 417 can be arranged on the sidewall of at least one of the mold plates 41 of the polyurethane elastomer pad forming mold 4, that is, the fitting groove III 417 can be arranged on only one mold plate 41, or a corresponding slot can be formed on two mold plates 41, and the insert 418 is detachably fitted in the fitting groove III 417, at this time, when the polyurethane elastomer pad forming mold 4 has multiple groups, the insert 418 is correspondingly provided with multiple inserts, and the diameters of the exhaust holes 415 on the multiple inserts 418 are inconsistent, so as to control the diameter of the exhaust hole 415 of the middle polyurethane elastomer pad forming mold 4 to be smaller than that of the outer polyurethane elastomer pad forming mold 4. At this time, before or after the multiple polyurethane elastomer pad forming molds 4 are closed, the insert 418 with the selected size of the exhaust hole 415 is fitted into the fitting groove III 417. Preferably, a rope 4181 is arranged above the insert 418, which facilitates the disassembly and assembly of the insert 418.

[0081] In one of the embodiments, referring to the accompanying drawings Figure 20The upper, lower, left and right sides of the polyurethane elastomer pad forming die 4 can be provided with exhaust holes 415. The exhaust holes 415 can be in the form of multiple round holes or one strip-shaped slot hole. The round holes or strip-shaped slot hole can be provided on only one of the mold plates 41, or can be provided as a half hole enclosed by two mold plates 41.

[0082] The process of injection molding is as follows: after all the molds are closed, the pouring pipe 7 is inserted into the main injection hole 416, the pouring material is poured from the main injection hole 416 to the through hole 414, and then flows into multiple pouring ports 412. The anti-backflow ball 413 of the multiple polyurethane elastomer pad forming dies 4 is pushed to the large end of the inclined hole 4121 by the pressure of the pouring material, without affecting the pouring of the pouring material into the mold cavity 411. In this process, all the polyurethane elastomer pad forming dies 4 are injected at the same time. Since the pouring material will preferentially enter from the pouring port 412 close to the main injection hole 416, the polyurethane elastomer pad forming die 4 located in the middle will be filled first, and then the polyurethane elastomer pad forming die 4 close to the two sides will be filled in turn, achieving the purpose of overall circulation. The air in the mold cavity 411 is discharged from the exhaust hole 415. When the material overflows from the exhaust hole 415 on the outer side with a large diameter, all the mold cavities 411 are filled, at which time the pouring is stopped and the pouring pipe 7 is pulled out. The anti-backflow ball 413 of the mold is reset to the lowermost part of the inclined hole 4121 by the pressure of the internal material and the self-weight of the anti-backflow ball 413, and blocks the injection hole 4122. When the exhaust hole 415 is in the form of a strip-shaped slot with a thickness of 0.2±0.05, a quantitative pouring mode is adopted. Without visually observing whether the material overflows, it is determined whether the quantitative pouring is complete.

[0083] The above is only an embodiment of the present application, and does not limit the present application in any way. Any person skilled in the art can make many possible changes, modifications or modifications to the technical solution of the present application without departing from the scope of the technical solution of the present application, and equivalent embodiments of equivalent changes. Therefore, any simple modification, equivalent change and modification of the above embodiments made according to the technical essence of the present application should fall within the scope of protection of the technical solution of the present application.
