Technical Field

[0001] The utility model relates to the technical field of punching and cutting of silicone placemats, in particular to a punching and cutting mould for silicone placemats. Background Art

[0002] Placemats are dining items that can protect and decorate the table. Their main function is to prevent direct contact between tableware and the tabletop, reduce friction between the tableware and the tabletop, and protect the tableware and the tabletop. Since homes, restaurants, coffee shops and other places have different requirements for the size of placemats, large pieces of silicone placemats need to be cut to produce silicone placemats of various sizes to meet the needs of different customers.

[0022] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. The preferred embodiments of the present invention are given in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0023] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be an intermediate element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be an intermediate element at the same time.

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0025] See also Figures 1 to 4 , which is a silicone placemat punching mold according to one embodiment of the utility model, includes a fixing base 10, an upper mold assembly 20 that can be lifted and connected to the fixing base 10, and a lower mold assembly 30 that can be lifted and connected below the upper mold assembly 20; the lower mold assembly 30 corresponds to the upper mold assembly 20.

[0026] The fixing seat 10 includes a fixing seat body 11 arranged in a U shape and linear bearings 12 installed on inner walls of two opposite sides of the fixing seat body 11 .

[0027] The upper die assembly 20 includes a slide bar 21 matched with the linear bearing 12, an upper die carrier plate 22 installed on the top of the two slide bars 21, an upper die 23 elastically connected to the bottom surface of the upper die carrier plate 22, a cutter 24 fixedly connected to the bottom surface of the upper die carrier plate 22, and an upper die driving cylinder 25 installed on the bottom surface of the fixed seat body 11; the piston rod of the upper die driving cylinder 25 is connected to the bottom end of the slide bar 21 through an adapter plate 26 to drive the upper die 23 and the cutter 24 to perform lifting and lowering movements.

[0028] In this embodiment, a knife receiving groove 230 is provided in the middle of the bottom surface of the upper mold 23 , and the cutting knife 24 is located inside the knife receiving groove 230 . The blade width of the cutting knife 24 is smaller than the groove depth of the knife receiving groove 230 .

[0029] The lower mold assembly 30 includes a lower mold carrier plate 31 connected to the sliding rod 21 by a sliding sleeve, a lower mold 32 fixedly installed on the top surface of the lower mold carrier plate 21, a material guide plate 33 extending outward from opposite sides of the lower mold 32, and a lower mold driving cylinder 34 installed on the ground of the fixed seat body 11; the piston rod of the lower mold driving cylinder 34 passes through the fixed seat body 11 upward and is connected to the lower mold carrier plate 31 to drive the lower mold carrier plate 31 to slide along the sliding rod 21, which can be used to adjust the distance between the lower mold carrier plate 31 and the fixed seat body 11, thereby adapting to silicone placemats of different thicknesses.

[0030] The lower mold 32 corresponds to the upper mold 23. In the present embodiment, an avoidance groove 320 is provided in the middle of the top surface of the lower mold 32. The avoidance groove 320 is provided corresponding to the knife receiving groove 230. The avoidance groove 320 is used to accommodate the cutting knife 24. That is, after the cutting knife 24 falls to cut the silicone placemat, it continues to fall and be accommodated in the avoidance groove 320, thereby ensuring that the silicone placemat is completely cut.

[0031] During punching, the upper mold assembly 20 falls, and the upper mold 23 first contacts the silicone placemat. Since the upper mold 23 has a certain elasticity, it can achieve elastic contact when contacting the silicone placemat, that is, it can ensure sufficient pressure to firmly fix the silicone placemat, and will not damage the silicone placemat due to excessive pressure. Then, the cutter 24 emerges from the inside of the knife groove 230 and continues to fall. The side walls of the knife groove 230 on both sides can pre-press the silicone placemat before the cutter 24 cuts. Since the silicone placemat is soft in texture, if it is not pre-pressed, the incision deformation is easy to occur during cutting, affecting the cutting quality and the aesthetics of the product. When the cutter 24 continues to fall and exceeds the knife groove 230, it will directly contact and cut the silicone placemat. At this time, since the side walls of the knife groove 230 have pre-pressed the silicone placemat, the cutter 24 can cut more stably and accurately, effectively preventing the incision deformation.

[0032] The above-mentioned silicone placemat punching mold has a simple structure and is easy to operate. The silicone placemat is pre-pressed by using the opposite sides of the knife groove 230, and the cutter 24 falls to cut the silicone placemat. The punching operation can be performed quickly and continuously, and the cutting accuracy and repeatability can be guaranteed, which greatly improves the production efficiency and shortens the production cycle.

[0033] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0034] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
