Description

Technical Field

[0001] This utility model relates to the field of hoisting equipment technology, and specifically to a fastener mold hoisting device. Background Technology

[0002] Die casting molds are tools used to cast metal parts. The basic process of die casting is as follows: molten metal is first poured into the mold cavity at low or high speed. The mold has movable cavity surfaces, which are pressurized and forged as the molten metal cools. This process eliminates shrinkage cavities and porosity defects in the blank and also makes the internal structure of the blank reach the forged state with broken grains. Generally, a pad is placed on the ground, and then the die casting mold is placed on the pad. Lifting equipment is required to lift the die casting mold.

[0003] However, existing hoisting mechanisms often use wire ropes to hoist molds. During the hoisting process, the molds are prone to swaying, making it difficult to maintain their balance and causing slippage between the hook and the upper mold. In addition, the wire ropes need to be disassembled and reassembled before and after hoisting, which is time-consuming and labor-intensive. Utility Model Content

[0004] This invention provides a fastener mold hoisting device to solve the problems of the prior art.

[0005] The objective of this utility model can be achieved through the following technical solution: a fastener mold hoisting device, comprising: a base, a hoisting frame disposed on the side of the base, and a hoisting mechanism disposed on the hoisting frame. The hoisting mechanism includes a lifting assembly and a hoisting component. The lifting assembly includes a hoisting motor fixedly disposed on the upper end of the hoisting frame, a reciprocating threaded rod rotatably disposed within the hoisting frame, and a lifting seat. One end of the reciprocating threaded rod passes through the upper end of the hoisting frame and is drivenly connected to the hoisting motor. The lifting seat is threadedly connected to the reciprocating threaded rod. The hoisting component includes a double-headed cylinder fixedly disposed on the lifting seat, a hoisting arm disposed at the end of the piston rod of the double-headed cylinder, and a locking member slidably disposed on the hoisting arm. The locking member has a locking pin and a hook respectively disposed on both sides of its bottom.

[0006] In a further improvement, the upper end of the locking member is provided with a threaded hole, and a limit bolt can be threadedly connected in the threaded hole. The lower end of the limit bolt can abut against the upper surface of the lifting arm.

[0007] As a further improvement, the front end of the lifting arm is threaded with a locking bolt.

[0008] In a further improvement, a counterweight rod is provided on the side of the base away from the lifting frame, and several counterweight blocks are provided on the counterweight rod.

[0009] In a further improvement, the hoisting frame is equipped with guide columns, and the lifting seat is slidably mounted on the guide columns.

[0010] As a further improvement, the base is provided with a push handle on the side and rollers at the bottom.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. In actual use, this utility model first moves the equipment to the position of the mold to be hoisted, then controls the piston rod of the double-headed cylinder to move to both sides, so that the hoisting arm opens. Then, the hoisting motor is started again, and the lifting seat is moved above the fastener mold by the reciprocating motion of the reciprocating threaded rod. Then, the position of the locking part on the hoisting arm is adjusted so that the locking pin on the locking part corresponds to the hoisting groove of the mold. Then, the piston rod of the double-headed cylinder is controlled to move inward, and the locking pin is used to limit the mold. Finally, the hoisting motor is started to lift the mold and complete the hoisting. The adjustable hoisting arm and locking part can meet the hoisting of molds of different sizes. Moreover, there is no need to connect with hoisting ropes during the hoisting process, which improves the hoisting efficiency.

[0013] 2. In actual use, this utility model allows for the selection of appropriate counterweights to counterweight the molds to be hoisted, preventing the equipment from tipping over and damaging the molds due to instability caused by the large weight of the molds during hoisting, and reducing the risk of mechanical injury.

[0020] The following is a description of the embodiments and appendices. Figures 1-3 The technical solution of this utility model will be further described below.

[0021] Example 1

[0022] A fastener mold hoisting device includes: a base 1, a hoisting frame 2 disposed on the side of the base 1, and a hoisting mechanism 3 disposed on the hoisting frame 2. The hoisting mechanism 3 includes a lifting assembly 31 and a hoisting assembly 32. The lifting assembly 31 includes a hoisting motor 311 fixedly disposed on the upper end of the hoisting frame 2, a reciprocating threaded rod 312 rotatably disposed in the hoisting frame 2, and a lifting seat 313. One end of the reciprocating threaded rod 312 passes through the upper end of the hoisting frame 2 and is drivenly connected to the hoisting motor 311. The lifting seat 313 is threadedly connected to the reciprocating threaded rod 312. The hoisting assembly 32 includes a double-headed cylinder 321 fixedly disposed on the lifting seat 313, a hoisting arm 322 disposed at the end of the piston rod of the double-headed cylinder 321, and a locking member 323 slidably disposed on the hoisting arm 322. The locking member 323 has a locking pin 3231 and a hook 3232 respectively disposed on both sides of its bottom.

[0023] like Figures 1-3As shown, in actual use, this utility model first moves the equipment to the position of the mold to be hoisted. Then, the piston rod of the double-headed cylinder 321 is controlled to move to both sides, so that the hoisting arm 322 opens. The hoisting motor 311 is started again, and the lifting seat 313 is moved above the fastener mold by the reciprocating motion of the reciprocating threaded rod 312. The position of the locking member 323 on the hoisting arm 322 is adjusted again so that the locking pin 3231 on the locking member 323 corresponds to the hoisting groove of the mold. The piston rod of the double-headed cylinder 321 is controlled to move inward again, and the locking pin 3231 is used to limit the mold. Finally, the hoisting motor 311 is started to lift the mold and complete the hoisting. The adjustable hoisting arm 322 and the locking member 323 can meet the hoisting of molds of different sizes. Moreover, there is no need to connect with hoisting ropes during the hoisting process, which improves the hoisting efficiency.

[0024] The locking component 323 is equipped with hooks 3232 on both sides. When the mold to be hoisted does not have a locking groove that matches the locking pin 3231, the mold can be hoisted by using the hooks 3232 and the hoisting rope, thus improving the applicability of the equipment.

[0025] As a further preferred embodiment, the upper end of the locking member 323 is provided with a threaded hole 3233, and a limit bolt 3234 can be threadedly connected in the threaded hole 3233. The lower end of the limit bolt 3234 can abut against the upper surface of the lifting arm 322.

[0026] Specifically, during the hoisting process, the locking component 323 is locked by the limiting bolt 3234 to prevent the locking component 323 from sliding during the hoisting process.

[0027] As a further preferred embodiment, the front end of the lifting arm 322 is threaded with a locking bolt 3221, which limits the movement of the locking component 323 during the lifting process and prevents it from slipping off the lifting arm 322.

[0028] As a further preferred embodiment, a counterweight rod 11 is provided on the side of the base 1 away from the lifting frame 2, and a plurality of counterweight blocks 12 are provided on the counterweight rod 11.

[0029] Specifically, in actual use, appropriate counterweights 12 should be selected to counterweight the molds to be hoisted, so as to avoid the equipment from tipping over and damaging the molds due to the instability of the center of gravity caused by the large weight of the molds during hoisting, and at the same time reduce the risk of mechanical injury.

[0030] As a further preferred embodiment, the hoisting frame 2 is provided with a guide column 21, and the lifting seat 313 is slidably disposed on the guide column 21.

[0031] As a further preferred embodiment, the base 1 is provided with a push handle 13 on its side and a roller 14 at its bottom to facilitate equipment transportation.

[0032] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
