Description

Technical Field

[0001] The utility model belongs to the technical field of packaging box molding, in particular to a folding box positioning molding die. Background Art

[0002] At present, many packaging boxes include an outer box and an inner box, and the inner box is placed inside the outer box, such as chewing gum packaging boxes, cigar packaging boxes, etc. The inner box is generally made of a plate folded into a box body having a bottom surface, an end surface, a short side, a long side, a short top surface 15 and a cover plate. The applicant's prior application for a Chinese utility model patent with publication number CN216885431U claims to protect a folding box mold structure and a folding mechanism. The technical solution disclosed in the patent document includes a mold body, which includes a bottom surface, a top surface and a side surface; the bottom surface, the top surface and the side surface are provided with adsorption holes, and the mold body is provided with an airflow channel connected to each adsorption hole, and the airflow channel is connected to the exhaust system; the top surface is provided with a connecting portion for fixing and installing the mold body. The sheet material to be folded into the inner box is adsorbed on the bottom surface of the mold body. When the side and top surfaces of the inner box are folded, the exhaust system forms negative pressure in each adsorption hole, so that the internal folded part can be adsorbed and attached to the corresponding outer surface of the mold body. When the folded inner box is loaded into the outer box, it is only necessary to put the outer box on the mold with the folded inner box, so that the inner box can be smoothly loaded into the outer box, avoiding the problem that the inner box is loose due to the rebound force after folding, which reduces the effect of transferring the inner box into the outer box; thus improving the efficiency of the combination of the inner box and the outer box. The applicant has also obtained the Chinese utility model patent with publication number CN217435132U. The solution of the patent document technology is to set the mold in the publication number CN216885431U on a turntable to realize automatic box folding and improve efficiency.

[0003] However, the inner box completes the folding of the short top surface of the paper box at the third folding position. Since the end of the short top surface is only one and has a certain length, when the turntable rotates at high speed, due to inertia and air flow resistance, the short top surface will bend upward, thus affecting the subsequent combination of the inner box and the outer box. Utility Model Content

[0004] The utility model aims to provide a folding box positioning and forming mold, which solves the problem that the existing inner box folding box mold causes the short top surface of the inner box to be tilted.

[0005] To achieve the above-mentioned purpose, an embodiment of the utility model provides a folding box positioning and forming mold, including a mold body. The mold body has a rectangular structure. An installation portion extends upward from the top side of the mold body. The installation portion is arranged close to one end side of the mold body and forms a top side forming area with the other end side; it also includes a pressing plate and a clamping drive component. The clamping drive component is arranged on the top side of the mold body, the pressing plate is connected to the clamping drive component, and the clamping drive component drives the pressing plate to be clamped in the forming area.

[0006] Furthermore, a protrusion extends from the back side of the mounting portion, and the bottom of the protrusion is higher than the top side of the mold body, so as to avoid the molding surface on the back side of the mold body.

[0007] Furthermore, a connection portion is extended upward from the top side of the mold body, the pressing plate is pivotally connected to the connection portion, and the pressing driving member drives the pressing plate to flip and press on the forming area.

[0008] Furthermore, the clamping drive member is a cylinder arranged on the top side of the mold body, and a transition portion extends from one side of the pressing plate, the transition portion is pivotally connected to the clamping drive member; the transition portion and the pressing plate are arranged at an acute angle.

[0009] Furthermore, a plurality of adsorption holes are arranged on the bottom side of the mold body, and the adsorption holes are connected to the negative pressure system, so that negative pressure is formed on the bottom side of the mold body.

[0010] Furthermore, the mold body comprises a main body and a bottom cover, a cavity is arranged on the bottom side of the main body, the bottom cover covers the bottom side of the cavity, and adsorption holes are arranged on the bottom cover.

[0011] Furthermore, a locking portion extending into the cavity is provided on the bottom side of the main body, and a connecting hole is provided on the locking portion, through which a locking screw passes to be fixedly connected with the mounting portion.

[0012] Furthermore, an air flow channel is provided in the mounting portion, the air flow channel is communicated with the cavity, and an air hole is provided on the back side of the mounting portion, the air hole is communicated with the air flow channel.

[0013] The above one or more technical solutions in the folding box positioning and forming mold provided by the embodiment of the utility model have at least the following technical effects:

[0014] When the short top edge of the paper box is folded to the forming area, the pressing drive drives the pressing plate to press the short top edge of the paper box in the forming area to prevent it from being loose. Therefore, when the mold body rotates at high speed with the turntable, the short top surface will not be lifted, thereby ensuring smooth assembly after forming. In addition, since the pressing plate presses the short top surface after forming, the rotation speed of the turntable can be accelerated, thereby improving the forming efficiency.
