Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

Referring to fig. 1 and 2, an embodiment of the present invention provides a mold opening assembly for processing a square product, including a base 1, four sliders 2 and a driving mechanism for driving the sliders 2 to be disengaged from a product 9 buckle position, four of the sliders 2 are all disposed on the base 1, and four of the sliders 2 enclose and form a groove for forming the square product 9, wherein a feed port for injecting a material of a feeding device 3 is disposed on one of the sliders 2, and the feed port is communicated with the groove. In this embodiment, four sliders 2 enclose to form a square, the four sliders 2 are all rectangular, the square and the base form a groove, the material of the feeding device 3 can be injected into the groove, and after cooling, a square product 9 with four surfaces can be formed. And then the sliding block 2 is withdrawn by a driving mechanism to obtain a molded product 9. For the injection of the material, a feed inlet is arranged on one of the slide blocks 2, then the feed inlet is communicated with the groove, the injected material can enter the groove, and further a required square product 9 is obtained, for the convenience of description with the accompanying drawings, the slide block with the feed inlet is defined as a feed slide block a, which is different from the other three slide blocks 2.

As an optimized solution of the embodiment of the present invention, please refer to fig. 1 and 2, the driving mechanism includes a plurality of driving assemblies for driving each of the sliding blocks 2 to be disengaged from the fastening position of the product 9, the number of each of the driving assemblies is the same as that of each of the sliding blocks 2, and the driving assemblies drive the corresponding sliding blocks 2. In this embodiment, the four sliders 2 are all driven by the driving assembly to realize independent driving, and certainly, one set of driving device may be used to simultaneously drive the four sliders, which is not limited in this embodiment.

In order to further optimize the above scheme, please refer to fig. 1 and fig. 2, the driving assembly for driving the slider 2 with the feeding hole and the three driving assemblies for driving the other three sliders 2 respectively include an ejector pin 4 for propping the slider 2 and a driving member for driving the ejector pin 4 to extend out, and the driving member is installed in the seat body 1. In the present embodiment, the driving manner is to push the slide block 2 by the ejector pin 4, and only the pushing direction needs to be set, and the driving member is a member having a linear driving force, such as an air cylinder, an electric push rod, and the like. Of course, other existing driving methods are possible besides the above driving method, and the details thereof will not be described here.

As an optimization scheme of the embodiment of the present invention, please refer to fig. 1 and fig. 2, the slider 2 having a feeding port is provided with a cold runner 8 for cooling the material, and the cold runner 8 surrounds the feeding port. In this embodiment, the material is cooled by the cold runner 8 before entering the groove, so that the forming speed of the product 9 can be increased, and the production efficiency can be improved.
