Description

Technical Field

[0001] The utility model relates to the technical field related to plate taking of an injection molding machine, in particular to an automatic lifting plate taking device for an injection molding machine. Background Art

[0002] When removing the die-cast filter plates from a traditional injection molding machine, the filter plates often fall into the machine during injection molding. When a certain number of filter plates have fallen into the machine, the machine stops working and the filter plates are manually cleaned and hoisted out of the machine before being used again. This method has the following problems: 1. When the dynamic mold of the injection molding machine pushes out the filter plates, the filter plates fall directly into the internal space of the injection molding machine. Due to a certain height difference, the shape of the filter plates will be more or less damaged, and subsequent repairs will be required; 2. After the equipment has been running for a certain period of time and enough filter plates have accumulated, the equipment needs to be shut down. The downtime depends on the time it takes for workers to enter the equipment to move the filter plates, which greatly reduces the efficiency of the injection molding machine; 3. Manually entering the injection molding machine to move the filter plates poses certain safety hazards, and there is still a certain height difference between the inside of the injection molding machine and the operating platform.

[0026] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention and are not used to limit the present invention.

[0027] Example: Figure 1-7 As shown, the present invention provides an automatic lifting and plate removal device for an injection molding machine, comprising a scissor lift 1 and a track 2. The top of the scissor lift 1 is provided with a receiving platform 3 for receiving the filter plate, and the scissor lift 1 moves along the track 2. The scissor lift 1 is arranged on the track 2, so that the scissor lift 1 can be fed into the injection molding machine along the track 2. After the injection molding machine opens the mold, the scissor lift 1 raises the receiving platform 3 to receive the filter plate pushed out of the movable mold. This completes automatic plate removal, eliminating the need for manual plate removal, thereby effectively improving work efficiency. Furthermore, multiple filter plates can be mechanically stacked. Once a certain number is reached, the scissor lift 1 moves along the track 2 to remove the filter plate, facilitating subsequent processing of the filter plate. The scissor lift 1 is a well-known technical product, so its specific structure and working principle will not be detailed here.

[0028] Among them, it also includes a laser distance measuring switch 4 arranged on the movable mold and used to measure the opening distance between the movable mold and the fixed mold, so that the opening distance between the movable mold and the fixed mold can be measured. After the laser distance measuring switch 4 measures that the relative width of the mold part is about 200mm greater than the width of the elevator, the injection molding machine equipment stops moving; and when the opening distance between the movable mold and the fixed mold is greater than the width of the material receiving platform 3 to meet the entry requirements of the material receiving platform 3, the scissor lift 1 will drive the material receiving platform 3 to rise and send the material receiving platform 3 to the material receiving position between the movable mold and the fixed mold to avoid collision.

[0029] Among them, the walking wheels 5 at the bottom of the scissor lift 1 and running along the track 2 are moved by the walking wheels, which effectively reduces friction and facilitates the movement of the scissor lift 1. The scissor lift 1 can be provided with a motor to drive the walking wheels to rotate, wherein the motor is not drawn in the figure, so that it is electrically driven and easy to operate. A linear limiting mechanism 6 is provided between the track 2 and the scissor lift 1, which plays a role in limiting the scissor lift 1 and avoids derailment between the scissor lift 1 and the track.

[0030] Among them, the linear limiting mechanism 6 includes a side plate 7 arranged on the inner side of the track 2 and pointing vertically downward. The bottom of the scissor lift 1 is equipped with side wheels 8 that travel along the side plates 7. The cooperation between the side plates 7 and the side wheels 8 is used to limit the left and right positions to avoid derailment. In the actual installation process, the side wheels 7 are installed by adjusting bolts.

[0031] The grating switch 9 is also provided between the movable mold and the fixed mold. The grating switch 9 is used to detect the lifting height of the scissor lift 1. The scissor lift 1 is lifted to the grating switch on the injection molding machine and stops moving when it reaches the upper limit of the scissor lift 1. Then, the movable mold on the injection molding machine has a push column to push the processed filter plate in the movable mold to drop it onto the receiving platform 3. Then the receiving platform 3 falls and falls to the lower limit of the equipment.

[0032] Among them, the scissor lift 1 is provided with a limit sensor 10 for detecting the lowest point of the scissor lift 1, to detect the lower limit of the material receiving platform 3 on the scissor lift 1, so that the scissor lift 1 is at the lowest position, ensuring a certain safety gap between the injection molding machine and the scissor lift 1.

[0033] Wherein, a limiting mechanism for limiting the movement of the scissor lift 1 is provided between the scissor lift 1 and the track 2.

[0034] The limiting mechanism is an electromagnet 12 arranged at the end of the body of the scissor lift 1. The track 2 is made of steel. The bottom of the electromagnet 12 fits the surface of the track 2. In this way, after the scissor lift 1 moves to the specified position, the electromagnet is powered on to be adsorbed together with the track, thereby playing a fixing role.

[0035] The surface of the receiving platform 3 is provided with a roller conveyor 13. The laying direction of the track 2 is parallel to the moving direction of the movable mold on the injection molding machine.

[0036] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
