Description

Technical Field

[0001] This utility model relates to the field of mold replacement technology, specifically a multi-functional hoisting and mold replacement device. Background Technology

[0002] In the production of plastic products such as mecha toys, due to the time-sensitive and diverse nature of toy products, injection molding machines need to frequently change production molds to meet the injection molding requirements of different toy parts. Molds are usually heavy and large in size. Traditionally, mold changing mainly relies on gantry cranes installed in the injection molding workshop. The lifting mechanism of the gantry crane lifts the mold and moves it to a designated workstation for installation or replacement.

[0003] However, in actual operation, during hoisting and movement, molds are prone to collisions with other equipment in the workshop due to limited operating space or insufficient human control precision. Since mold materials typically have high hardness, rigid contact can not only cause surface damage or structural deformation of the mold itself, but also cause varying degrees of damage to the equipment being collided with, increasing maintenance costs and affecting production efficiency. Utility Model Content

[0004] This utility model addresses the technical problems existing in the prior art by providing a multi-functional hoisting and mold changing device. This device solves the problem that when a mold collides with other equipment in the workshop during hoisting and movement, it causes surface damage or structural deformation to the mold itself, as well as damage to the collided equipment.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A multi-functional hoisting and mold changing device, comprising:

[0006] Gantry crane, the gantry crane including a lifting mechanism;

[0007] At least four chains, one end of each of the at least four chains being detachable from the lifting end of the lifting mechanism;

[0008] A support fixture, wherein the four outer surfaces of the support fixture are respectively fixed to one end of four chains;

[0009] An electromagnet, which is embedded in the top of a support fixture;

[0010] A buffer airbag surrounds the four sides of the support fixture.

[0011] A displacement assembly is disposed at the bottom of the support fixture to allow the support fixture to move on the ground.

[0012] The beneficial effects of this utility model are:

[0013] 1) Buffer airbags are installed around the four sides of the support fixture. Utilizing the flexibility of these airbags, even if the support fixture comes into contact with workshop equipment during mold hoisting and movement, rigid collisions are transformed into flexible contact, significantly reducing the risk of damage to the mold and equipment. This not only extends the mold's service life but also reduces the frequency and cost of equipment maintenance, significantly improving the economic efficiency of the production workshop. Furthermore, by embedding an electromagnet at the top of the support fixture and utilizing the magnetic attraction generated when the electromagnet is energized, the mold is firmly attached to the support fixture, achieving stable mold positioning and effectively preventing the mold from slipping due to vibration or tilting during hoisting. Simultaneously, four chains are fixed to the four sides of the support fixture and lifted by a lifting mechanism, forming a secondary positioning protection for the mold. Even in the event of an accidental failure of the electromagnet, the chain enclosure structure can still effectively restrain the mold, preventing it from falling and significantly reducing the risk of the mold falling and injuring workers or damaging equipment, thus comprehensively improving the safety of hoisting operations.

[0014] 2) By embedding an electromagnet into the top of the support fixture, a flat surface without protrusions is formed on the top of the support fixture, which serves as a fixed platform for the mold. This not only facilitates the quick placement of the mold, but also simplifies the mold removal process. Operators do not need to handle complicated loading and unloading processes, and can quickly load and unload the mold, which significantly improves the efficiency of mold replacement.

[0015] Based on the above technical solution, the present invention can be further improved as follows.

[0016] Furthermore, the lifting mechanism is a chain crane.

[0017] Furthermore, the gantry crane also includes a crossbeam, a fixed plate, and multiple rollers, with the fixed plate located on both sides of the crossbeam.

[0018] Furthermore, one side of each of the rollers is rotatably connected to the side of the fixed plate near the crossbeam via a rotating shaft, and the chain crane is fixed to the bottom of the fixed plate.

[0019] Furthermore, one end of each of the four chains is respectively fitted onto the hook of the chain crane.

[0020] Furthermore, the displacement component includes multiple movable slots and multiple balls, with the multiple movable slots arranged in a linear array on the bottom of the support fixture, wherein each movable slot is two-thirds spherical.

[0021] Furthermore, each of the balls is positioned inside each active slot.

[0022] The beneficial effect of adopting the above-mentioned further solution is that the ball can roll freely in the two-thirds spherical movable groove, so that the carrying fixture has the ability to move with low friction and in multiple directions when moving on the ground, which facilitates the flexible transfer of the carrying fixture in the workshop, assists in the transportation of the mold from the storage area to the injection station for the last distance, and solves the problem of the moving area that the gantry cannot cover.

[0023] Furthermore, the diameter of the ball is smaller than the diameter of the movable groove.

[0024] The advantage of adopting the above-mentioned further solution is that it ensures that the balls can roll freely in the moving groove.

[0025] Furthermore, the opening diameter of the movable groove at the bottom of the bearing fixture is smaller than the diameter of the ball.

[0026] The beneficial effect of adopting the above-mentioned further solution is that by setting the opening diameter of the movable groove at the bottom of the support fixture to be smaller than the diameter of the ball, the ball is ensured to be securely embedded in the movable groove, effectively preventing the ball from falling out.

[0032] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0033] In the production of plastic products such as mecha toys, due to the time-sensitive and diverse nature of toy products, injection molding machines need to frequently change production molds to meet the injection molding requirements of different toy parts. Molds are usually heavy and large in size. Traditionally, mold changing mainly relies on gantry cranes installed in the injection molding workshop. The lifting mechanism of the gantry crane lifts the mold and moves it to a designated workstation for installation or replacement.

[0034] However, in actual operation, during hoisting and movement, molds are prone to collisions with other equipment in the workshop due to limited operating space or insufficient human control precision. Since mold materials typically have high hardness, rigid contact can not only cause surface damage or structural deformation of the mold itself, but also cause varying degrees of damage to the collided equipment, increasing maintenance costs and affecting production efficiency. To address these issues, the inventor has proposed a multi-functional hoisting and mold replacement device.

[0035] The present invention provides the following preferred embodiments.

[0036] like Figure 1 , Figure 2 ,and Figure 3 As shown, a multi-functional hoisting and mold changing device includes:

[0037] Gantry crane 100, gantry crane 100 includes a lifting mechanism;

[0038] At least four chains 200, one end of each of the at least four chains 200 being detachable from the lifting end of the lifting mechanism;

[0039] The support fixture 300 has four external surfaces fixed to one end of each of the four chains 200.

[0040] Electromagnet 400 is embedded in the top of the support fixture 300;

[0041] The cushioning airbag 500 surrounds the four sides of the support fixture 300.

[0042] A displacement assembly 600 is disposed at the bottom of the support fixture 300 to allow the support fixture 300 to move on the ground;

[0043] Buffer airbags 500 are installed around the four sides of the support fixture 300. Through the flexible characteristics of the airbags, even if the support fixture 300 comes into contact with workshop equipment during the mold hoisting and movement, the rigid collision can be transformed into a flexible contact, which greatly reduces the risk of damage to the mold and equipment. This not only extends the service life of the mold, but also reduces the frequency of maintenance and maintenance costs of workshop equipment, significantly improving the economic efficiency of the production workshop. In addition, by embedding an electromagnet 400 on the top of the support fixture 300, and using the magnetic attraction force generated by the electromagnet 400 after being energized, the mold is firmly attracted to the support fixture 300, realizing the stable positioning of the mold and effectively preventing the mold from slipping due to vibration or tilting during hoisting. At the same time, four chains 200 are fixed to the four sides of the support fixture 300 and are lifted by the lifting mechanism to form a secondary positioning protection for the mold. Even if the electromagnet 400 fails unexpectedly, the surrounding structure of the chains 200 can still effectively restrain the mold and prevent it from falling, greatly reducing the risk of the mold falling and injuring workers or damaging equipment, and comprehensively improving the safety of hoisting operations.

[0044] By embedding an electromagnet 400 into the top of the support fixture 300, a flat surface without protrusions is formed on the top of the support fixture 300, which serves as a fixing platform for the mold. This not only facilitates the quick placement of the mold, but also simplifies the mold removal process. Operators can quickly load and unload the mold without having to deal with a complicated loading and unloading process, which significantly improves the efficiency of mold replacement.

[0045] In this embodiment, as Figure 1 , Figure 2 ,and Figure 3 As shown, the lifting mechanism uses a chain crane 104.

[0046] In this embodiment, as Figure 1 , Figure 2 ,and Figure 3 As shown, the gantry crane 100 also includes a crossbeam 101, a fixed plate 102, and multiple rollers 103. The fixed plate 102 is located on both sides of the crossbeam 101. One side of each of the multiple rollers 103 is rotatably connected to the side of the fixed plate 102 near the crossbeam 101 via a rotating shaft. The chain crane 104 is fixed to the bottom of the fixed plate 102, allowing the rollers 103 to roll on the crossbeam 101, so that the fixed plate 102 and the chain crane 104 move along the trajectory of the crossbeam 101.

[0047] In this embodiment, as Figure 1 , Figure 2 ,and Figure 3 As shown, one end of each of the four chains 200 is fitted onto the hook of the chain crane 104.

[0048] In this embodiment, as Figure 1 , Figure 2,and Figure 3 As shown, the shifting assembly 600 includes multiple movable slots 601 and multiple balls 602. The multiple movable slots 601 are arranged in a linear array on the bottom of the support fixture 300. Each movable slot 601 is two-thirds spherical, and each ball 602 is placed inside each movable slot 601. The ball 602 can roll freely within the two-thirds spherical movable slot 601, giving the support fixture 300 low friction and multi-directional movement capability when moving on the ground. This facilitates the flexible transfer of the support fixture 300 within the workshop, assists in the final transportation of the mold from the storage area to the injection molding station, and solves the problem of movement areas that the gantry cannot cover.

[0049] In this embodiment, as Figure 1 , Figure 2 ,and Figure 3 As shown, the diameter of the ball 602 is smaller than the diameter of the movable groove 601, ensuring that the ball 602 can roll freely in the movable groove 601.

[0050] In this embodiment, as Figure 1 , Figure 2 ,and Figure 3 As shown, the opening diameter of the movable groove 601 at the bottom of the support fixture 300 is smaller than the diameter of the ball 602. By setting the opening diameter of the movable groove 601 at the bottom of the support fixture 300 to be smaller than the diameter of the ball 602, it is ensured that the ball 602 is securely embedded in the movable groove 601, effectively preventing the ball 602 from falling off.

[0051] The specific working process of this utility model is as follows:

[0052] Buffer airbags 500 are arranged around the four sides of the bearing fixture 300. Through the flexible characteristics of the airbags, even if the bearing fixture 300 comes into contact with the workshop equipment, the rigid collision can be transformed into a flexible contact.

[0053] After the mold is moved to the top of the support fixture 300, the electromagnet 400 is energized, and the resulting magnetic force firmly attracts the mold to the support fixture 300, achieving stable positioning of the mold. Finally, one end of each chain 200 is hooked onto the hook of the chain crane 104.

[0054] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
