Description

Technical Field

[0001] This utility model specifically relates to an automatic punching device for toy tires. Background Technology

[0002] Sprue refers to the waste material from the injection molding machine nozzle as it fills the mold until it reaches the finished product. After the entire injection molding process, the finished product is often still attached to the sprue. It requires manual shearing or other equipment for secondary processing to remove residual plastic material from the sprue and separate the product from the sprue, resulting in a complete injection-molded product. Therefore, after injection molding, toy tires need to be manually placed into the equipment, and then the machine is operated to cut and process the sprue in the toy tire.

[0003] Traditional punching requires manual activation of the punch after the tire is placed manually, or semi-automatic equipment requires operators to frequently participate in each work cycle. This results in slow production pace, high labor costs, and the inability to achieve continuous operation or form an efficient production line. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an automatic punching device for toy tires.

[0005] The technical solution adopted by this utility model to solve its technical problem is: An automatic punching device for toy tires includes a punching base, a column vertically inserted above the punching base, a support plate fixedly mounted on the column, a punching cylinder fixedly mounted above the support plate with its output end facing downwards, a solenoid valve fixedly mounted on one side of the punching cylinder and connected to the punching cylinder, a detachable and replaceable punching cutter head mounted on the output end of the punching cylinder, a PLC controller located on the other side of the punching cylinder and fixedly mounted on the support plate via a bracket, and a punching turntable movably mounted above the punching base, rotating around the column to adjust the punching position. The punching turntable includes a punching turntable body, a turntable drive motor located on one side below the punching turntable body and fixedly mounted on the punching base via a bracket, a toy tire positioning mold arranged in a ring around the edge of the punching turntable body and hollowed out in the middle, a driven gear ring fixedly mounted by screws at the center of the lower part of the punching turntable body with its meshing teeth facing downwards, and a bearing fitted inside the driven gear ring and assembled with the punching base.

[0006] Preferably, a through hole is provided in the center of the punching turntable body; The edge of the punching turntable is provided with corresponding to the toy tire positioning mold, with blanking holes at equal intervals.

[0007] Preferably, the turntable drive motor is connected to the PLC controller, and a drive gear is installed on the output end of the turntable drive motor.

[0008] Preferably, the toy tire positioning mold is a circular positioning mold that matches the shape of the toy tire.

[0009] Preferably, the punching base includes a fixing sleeve for supporting the punching turntable and the insert column, and a support seat for correspondingly supporting the toy tire positioning mold on the punching turntable.

[0010] Preferably, the lower end of the column is integrally formed with an insert head.

[0011] Preferably, the output shaft of the punching cylinder is provided with an external thread.

[0012] The beneficial effects of this utility model are as follows: 1. Multiple toy tire positioning molds are installed on the punching turntable body to form a "rotary" workbench. The PLC controller and turntable drive motor are integrated to realize a fully automatic cycle of feeding, rotating to the work station, automatic punching, and unloading. This allows the operator to load and unload materials at one work station. The punching cylinder works with the punching head to automatically punch holes at another work station, realizing assembly line operation and greatly increasing the output per unit time. 2. The meshing transmission of the driven gear ring and the driving gear has higher indexing accuracy and rigidity compared to simple friction transmission or belt transmission. It can ensure that each tire positioning mold can stop precisely under the punch. As a hollow circular positioning mold for the tire, the tire is embedded in the toy tire positioning mold, which fundamentally guarantees the uniqueness and correctness of the tire position during each punching. This ensures that the punching position of each product is exactly the same, which significantly improves product consistency and yield. Attached Figure Description
