Description

Technical Field

[0001] The utility model relates to the technical field of automobile manufacturing, in particular to a tire mold changing system. Background Technique

[0002] An automobile bumper is a safety device that absorbs and mitigates external impact forces and protects the front and rear parts of the vehicle body. Generally, the plastic bumper of an automobile is composed of three parts: an outer panel, a buffer material, and a cross beam. Among them, the outer panel and the buffer material are made of plastic, and the cross beam is stamped into a U-shaped groove with cold-rolled thin plate. The outer panel and the buffer material are attached to the cross beam. As a fixing structure of the bumper, the tire mold plays a crucial role in its processing production line.

[0003] The tire molds used for automobile bumper assembly mainly include two types: non-inverting tire molds and inverting tire molds. Among them, the non-inverting tire mold is the traditional assembly tire mold, which can be divided into a convex mold and a concave mold according to the differences in the basic framework and functions of the tire mold. Each bumper product requires two tire molds: a concave mold + a convex mold. The inverting tire mold is a single tire mold with the ability to invert. The product can be assembled in two states: concave mold and convex mold, through the inversion of the tire mold on the tire mold.

[0004] At present, the mold changing method for these two types of tire molds is manual mold changing. After the operator transports the tire mold to be changed to the mold changing trolley, the tire mold is installed on the tire mold base through manual operation. A mold changing trolley is required. The entire process involves many personnel, takes a long time, and has a low mold changing efficiency. Pure manual operation has potential safety hazards. Content of the Utility Model

After the die base 2 detects the signal that the tire die 4 is installed in place, it drives the clamping cylinder 22 to automatically clamp, realizing the fixation of the tire die 4.

[0038] Embodiment 2:

[0039] A die changing system for tires, as Figures 1-4 shown, includes a die rack 1, a die base 2, and a gripping robot 3 for gripping a tire die 4 and switching it between the die rack 1 and the die base 2.

[0040] The die rack 1 includes a die holder base 15 and support square steel 16. Multiple layers of die holders 11 are arranged in parallel at equal intervals on the support square steel 16. A die rack locating pin 12 capable of aligning with the tire die 4 is provided on the die holder 11. Tire die locating holes corresponding one-to-one to the die rack locating pins 12 are provided on the tire die 4. Laser material sensors 13 for detecting the type of the tire die are horizontally symmetrically provided on the die holder 11, which can effectively avoid misplacing the tire die.

[0044] A mold changing system for a mold includes a mold rack 1, a mold base 2, and a gripping robot 3 for gripping the mold 4 and switching it between the mold rack 1 and the mold base 2. The difference from Embodiment 2 is that in this embodiment, according to the shape of the mold, in order to enhance the stability and accuracy during mold positioning, the support positioning blocks 24 are arranged in a triangular shape on the bottom plate 23, and the position sensors 14 are also correspondingly arranged in a triangular shape on the mold frame 11.

[0045] This embodiment takes the male mold as an example to demonstrate the mold changing process. The working process of the female mold is the same. The specific working process is as follows:

[0046] At the beginning, the male mold ① is placed on the mold rack 11a, and the male mold ② is installed on the mold base 2. After the operator starts the mold changing program, the clamping cylinder 22 of the male mold ② automatically opens. The gripping robot 3 runs to the male mold ② station according to the PLC program to grip the male mold ②. After the screen displays the signal of gripping in place, it transports the male mold ② to the mold frame 11b. After the laser material sensor 13 of the mold frame 11b receives the signal, it places the male mold ② on the mold frame 11b. After the position sensor 14 receives the signal of being in place, the mold changing of the male mold ② can be completed. Subsequently, the gripping robot 3 grips the male mold ① and transports the male mold ① to the mold base 2 according to the PLC program. After the mold base 2 senses the position degree and the signal of being placed in place of the male mold ①, it drives the clamping cylinder 22 to automatically clamp. The gripping robot 3 resets, and the mold changing is completed.
