Description

Technical Field

[0001] The utility model relates to the technical field of household appliance injection molds, in particular to a household appliance injection mold transfer device. Background Art

[0002] Home appliance injection mold is a mold specially used for producing plastic parts of home appliances. It can be cast with different materials. Usually, thermoplastic plastics can be injected into a closed mold and formed after cooling. Some large home appliances have large shells and need to choose suitable injection molds. Therefore, they need to be transported with the help of transfer devices.

[0003] According to the "A transfer device for injection mold processing" with Chinese patent publication number CN217293055U, it mainly describes that by arranging a limit spring and a limit plate inside the transfer box, when the injection mold is loaded, the limit spring will give elastic force to the push plate, so that the two push plates can limit the two ends of the injection mold, so that the injection mold can be stably inside the transfer box without the phenomenon of shaking and sliding, thereby ensuring its stability. Then, the transfer box is connected by two slings through a connecting rope, and the two slings are connected between the two slings by a connecting rope. The pulling force of the two slings can offset each other through the connecting rope, so that the transfer box can be kept from shaking during the transfer process. In this process, the box body used to transfer the injection mold will shake during the movement due to the traction of the rope, and it will be transmitted to the limit spring in the transfer box, causing the injection mold to shake in the transfer box, resulting in displacement.

[0004] Therefore, a household appliance injection mold transfer device is proposed to solve the problem that in the process, the box used to transfer the injection mold will shake due to the traction of the cable during the movement, and the shaking is transmitted to the limit spring in the transfer box, causing the injection mold to shake in the transfer box and cause displacement. Utility Model Content

[0005] The technical problem to be solved by the utility model is that the injection mold in the transfer box is affected by the rope and the limit spring, which may cause the injection mold to shake, so a transfer device for the injection mold of household appliances is proposed.

[0006] The technical solution adopted by the utility model to solve the technical problem is: a household appliance injection mold transfer device, including a fixed frame, a first motor is fixedly connected to one side of the fixed frame, a bidirectional screw is fixedly connected to the output end of the first motor, push plates are threadedly connected to two sides of the bidirectional screw that are far away from each other, a second motor is fixedly connected to the other side of the fixed frame, the output end of the second motor is fixedly connected to the first screw, the first screw is rotatably connected to one of the fixed frames and threadedly connected to the other fixed frame, an auxiliary rod is inserted into the bottom side of the fixed frame, a through hole is opened at the center of the fixed frame, and a support plate is inserted into the through hole.

[0007] As a preferred technical solution of the utility model, the fixing frame is located in the through hole and four sides away from each other are rotatably embedded with balls, and the balls are in contact with the support plate. By providing the balls, it is convenient to insert or remove the support plate.

[0008] As a preferred technical solution of the utility model, a spring top rod is inserted into the bottom side of the fixed frame, positioning holes are evenly opened on both sides of the support plate, and the end of the spring top rod is inserted into the positioning hole. By setting the spring top rod and the positioning hole, the support plate can be conveniently limited.

By arranging the spring rod and the connecting plate, a buffer can be provided and the wear between the injection mold and the components of the transfer box can be reduced.

[0010] As a preferred technical solution of the utility model, the support plate is glued to a pad at the center of the four spring rods, and the pad corresponds to the position of the connecting plate to improve the buffering effect.

[0011] The utility model has the following advantages: by setting a fixed frame that can be relatively far away and cooperating with a push plate that can be relatively movable, household appliance injection molds of different sizes are limited, and then support is provided by a support plate, and the support plate can be removed and the fixed frame and the clamping plate can be moved away from each other, so that the household appliance injection mold is automatically detached and disassembled conveniently.
