Description

Technical Field

[0001] The utility model relates to the technical field of strapping belt production, in particular to an adjustable strapping belt mould. Background Art

[0002] Also known as strapping tape, packaging strapping tape (strapping tape) is made of polyethylene, polypropylene resin, cold-rolled strip steel as the main raw materials, and also made of nylon and polyester as raw materials. It is made by extrusion and uniaxial stretching, and heat treatment and bluing. In addition to being used for sealing and strapping corrugated boxes, hot-rolled steel coils and cold-rolled steel coils, it can also be used to strap glass, pipes, materials, fruits, etc. When producing strapping tape, a mold is needed to perform molding processing on it. Among them, the "an adjustable strapping tape mold" disclosed in the application number "CN214163952U" has solved the production problem. Although there is a technical disadvantage of increased cost, there are still many defects in the actual use of devices with similar structures. For example, the overall fixed structure is relatively cumbersome, which makes it inconvenient for the staff to disassemble the inside of the mold later, resulting in inconvenience for the staff to maintain the inside of the mold. When the mold is less maintained, the inside will be severely worn, metal fatigue, and inner wall corrosion, thereby reducing the service life and stability of the mold; at the same time, it is inconvenient to adjust the mold according to production needs, which reduces the convenience of the mold when in use, so it is necessary to design an adjustable strapping mold. Utility Model Content

[0003] The utility model aims to provide an adjustable mould for a strapping belt to solve the problems raised in the above-mentioned background technology.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an adjustable mold for packing tape, comprising a mounting mold and a forming mold, a mounting flange is fixedly installed on the back of the mounting mold, the mounting mold and the bottom of the forming mold are movably connected by a mounting hinge, and a docking plate is fixedly installed on the back of the forming mold, a material distribution cavity is arranged inside the mounting mold, and three groups of forming cavities adapted to the material distribution cavity are arranged inside the forming mold, three groups of threaded rods are threadedly installed on the front face of the forming mold, and an adjustment plate adapted to the forming cavity is rotatably installed on the rear side of the threaded rod, an adjusting hand wheel is fixedly installed on the front face of the threaded rod, a locking rod is movably installed on the front side of the top of the mounting mold, and a locking plate is fixedly installed on the outside of the locking rod through a supporting spring, a locking seat adapted to the locking plate is fixedly installed on the top of the forming mold, and an auxiliary frame is fixedly installed on the bottom of the mounting mold.

[0005] A strapping adjustable mold using the technical solution is installed and fixed to the production injection molding machine through the mounting flange on the back, so that the raw material liquid in the production injection molded part can enter the material distribution cavity in the installation mold. The auxiliary frame can provide auxiliary support for the bottom of the installation mold during installation. The bottom of the installation mold and the molding mold are movably connected through the installation hinge, so that the installation mold and the molding mold can be easily matched. The docking plate increases the sealing of the installation mold and the molding mold when they are matched.

[0006] When the installation mold and the forming mold are matched, the raw material liquid in the material distribution cavity enters the forming cavity inside the forming mold, so that the strapping tape can be formed through the forming cavity, and the locking rod is fixedly connected to the locking seat through the locking plate, so that the installation mold and the closed top of the forming mold can be connected and locked through the locking rod and the locking seat, and the support spring can elastically support the locking plate, and the inside of the mold can be quickly opened and closed through the locking rod and the locking seat, so that it is convenient for the staff to clean and maintain the inside of the mold later. Regular cleaning and maintenance of the inside of the mold reduces the wear, fatigue and corrosion during use, thereby increasing the stability and life of the mold during use;

[0007] The threaded rod can be rotated to move the adjustment plate forward and backward in the molding cavity, so that the front and rear space of the molding cavity can be adjusted through the adjustment plate, thereby realizing the thickness adjustment control of the strapping tape during raw extrusion. The adjustment hand wheel is convenient for the staff to adjust the threaded rod and the adjustment plate, thereby increasing the convenience of the staff in adjusting the mold and improving practicality.

[0008] Preferably, a sealing convex strip is fixedly installed on the front of the installation mold, and a sealing groove adapted to the sealing convex strip is provided on the back of the docking plate. The sealing convex strip and the sealing groove can be sealed when the docking plate and the installation mold are docked.

[0009] Preferably, a grip sleeve is fixedly mounted on the outer wall of the locking rod, and an anti-skid groove is provided on the outer wall of the grip sleeve. The grip sleeve facilitates the staff to hold the locking rod when operating the locking rod, and the anti-skid groove increases the friction of the outer wall of the grip sleeve, thereby improving the stability of the staff when operating the locking rod.

[0010] Preferably, two sets of positioning rods are fixedly installed on the upper part of the back of the forming mold, and positioning sleeves adapted to the positioning rods are fixedly installed on the upper part of the front of the installation mold. The positioning rods and the positioning sleeves can be positioned when the forming mold and the installation mold are docked, thereby increasing the accuracy of the docking of the forming mold and the installation mold.

[0011] Preferably, a mounting hole is provided on the outer side of the mounting flange, and a sealing ring is fixedly installed on the back of the mounting flange. The mounting hole can be used to fix the mounting flange to the external injection molding machine through bolts, and the sealing ring increases the sealing performance of the mounting flange and the injection molding machine when they are installed.

[0012] Preferably, an auxiliary plate is fixedly mounted on the back of the auxiliary frame, and a rubber pad is fixedly mounted on the back of the auxiliary plate. The auxiliary plate increases the force bearing area when the auxiliary frame contacts the base of the injection molding machine, and the rubber pad performs flexible protection when the auxiliary plate contacts the base of the injection molding machine.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. By setting the cooperation between the installation mold and the molding mold, the installation hinge, the locking rod and the locking seat, the installation mold and the molding mold can extrude and mold the strapping tape stock solution, so that the strapping tape can be produced and processed. The installation hinge can movably connect the bottom of the installation mold and the molding mold. At the same time, the locking rod and the locking seat can connect and lock the top of the installation mold and the molding mold, thereby realizing the function of convenient opening of the interior of the mold, increasing the convenience of the staff in cleaning and maintaining the interior of the mold in the later stage, and improving the service life and stability of the mold.

[0015] 2. By setting the cooperation between the molding cavity, the adjustment plate and the threaded rod, the molding cavity can be molded with the strapping tape. The threaded rod can adjust the adjustment plate to move back and forth in the molding cavity by rotation. The thickness of the molding strapping tape in the molding cavity can be adjusted by adjusting the adjustment plate to move back and forth, so that the staff can adjust the mold according to the actual production needs, which increases the convenience of the staff in adjusting the mold and improves the practicality.
