Technical Field
The utility model relates to the technical field of cladding, in particular to a cladding mold assembly.
Background Art
A cladding mold assembly is a mold used for injection-molding one material onto another during the manufacturing process. This process generally adopts a mold configured to produce two or more different parts, wherein one part is molded onto another. The finished product is a single integrated assembly with multiple materials and functions.
Conventional silent belts are usually made of flexible materials such as rubber or silicone. Such materials are prone to bending and deformation, so the silent belts may twist and intertwine with one another during service.Meanwhile, poor chemical or mechanical compatibility between the cladding material and the substrate material may lead to inadequate bonding of the cladding surfaces. This results in time-consuming operation, high material consumption and reduced cladding efficiency.
Contents of the Utility Model
(1) Technical Problems to Be Solved
In view of the deficiencies in the prior art, the utility model provides a cladding mold assembly to solve the problems mentioned in the background art: conventional silent belts made of flexible materials such as rubber or silicone tend to bend and deform and thus intertwine during use; in addition, the cladding material and base material feature insufficient chemical or mechanical compatibility, which prevents tight bonding of cladding surfaces, causing waste of time, labor and materials and lowering cladding efficiency.
(2) Technical Solution
To achieve the above purpose, the utility model adopts the following technical solution:A cladding mold assembly, comprising:A workbench. A tape wheel is arranged on the right side of the upper surface of the workbench; a tape wheel damping device is mounted on the tape wheel. A spring and friction plates are installed inside the tape wheel damping device, and positioning strips are evenly distributed on the surface of the tape wheel damping device;
A multi-roller rolling mold arranged on the upper surface of the workbench. A sealing strip guide base is mounted on the right side of the upper surface of the multi-roller rolling mold;
A first top cladding roller for the sealing strip, arranged on the left side of the upper surface of the multi-roller rolling mold. A second corner cladding roller for the sealing strip is arranged on the left side of the first top cladding roller;a first lateral circular surface cladding roller for the sealing strip is arranged on the left side of the second corner cladding roller;a second lateral circular surface cladding roller for the sealing strip is arranged on the left side of the first lateral circular surface cladding roller;a first inner-groove opening roller for the sealing strip is arranged on the left side of the second lateral circular surface cladding roller;a second inner-groove opening roller for the sealing strip is arranged on the left side of the first inner-groove opening roller;a first inner-groove cladding roller for the sealing strip is arranged on the left side of the second inner-groove opening roller;a second inner-groove cladding roller for the sealing strip is arranged on the left side of the first inner-groove cladding roller;
Upper pressing rollers arranged on two sides of the upper surface of the multi-roller rolling mold. The upper pressing roller on the right is disposed between the second corner cladding roller for the sealing strip and the first lateral circular surface cladding roller for the sealing strip;the upper pressing roller on the left is disposed between the first inner-groove opening roller for the sealing strip and the second inner-groove opening roller for the sealing strip.
Preferably, mounting brackets are arranged on the upper surface of the multi-roller rolling mold at positions corresponding to the upper pressing rollers. Each mounting bracket is of a U-shaped structure. The upper pressing rollers are installed inside the mounting brackets, and the mounting brackets are used for installing the upper pressing rollers.
Preferably, a silent belt guide inlet is formed on the right side of the multi-roller rolling mold, and a silent belt enters the multi-roller rolling mold through the silent belt guide inlet.
Preferably, a bearing is installed in the inner cavity of the tape wheel damping device, and a bearing cover is mounted on the front face of the tape wheel damping device, enabling the tape wheel damping device to rotate.
Preferably, a tape wheel fixing assembly is mounted on the right side of the upper surface of the multi-roller rolling mold. A tape wheel connecting rod is installed on the front face of the tape wheel fixing assembly and connected to the inner ring of the bearing, so that the tape wheel can rotate stably.
Preferably, mounting grooves are formed on two sides of each mounting bracket. Connecting pieces are installed on two sides of each upper pressing roller. Screws are mounted on two sides of the upper surface of each mounting bracket and arranged inside the mounting grooves. Each screw penetrates through the corresponding connecting piece and is in threaded connection therewith. The screws can drive the connecting pieces to ascend and descend, so as to adjust the height of the upper pressing rollers.
Beneficial Effects
Compared with the prior art, the utility model has the following beneficial effects:In this cladding mold assembly, the silent belt is sleeved on the outer ring of the tape wheel damping device. Positioning strips are arranged on the outer ring to form an interference fit with the silent belt, generating static friction therebetween. When external pulling force is applied for material feeding, the silent belt rotates and drives the outer ring to rotate. The friction plates twist and deform the spring to generate restoring force. As the silent belt continues rotating, when the restoring force of the spring exceeds the static friction force between the silent belt and the outer ring, slipping occurs between them, the restoring force of the spring decreases, and the outer ring rotates together with the silent belt again until overload slipping takes place once more.After a section of material pulling is completed and the pulling operation pauses, the restoring force of the spring drives the outer ring and the silent belt to roll back, maintaining constant tension on the silent belt. This ensures consistent pulling force in each feeding cycle, improves the feeding stability of the silent belt, and prevents intertwining and knotting of silent belts.The top cladding rollers, lateral circular surface cladding rollers, inner-groove opening rollers and inner-groove cladding rollers for the sealing strip cooperate to squeeze the silent belt, achieving perfect bonding of the cladding surfaces, avoiding insufficient lamination and material waste, cutting costs and improving cladding efficiency.
