DETAILED DESCRIPTION

[0018] See also Figure 1-4As shown, the utility model is a mold changing trolley with horizontal alignment adjustment, comprising a first frame 1, on which a horizontal fine-adjustment platform 2 perpendicular to the forward direction of the first frame 1 is provided, and a hand push frame 3 for pushing the first frame 1 is provided at one end of the first frame 1 away from the external production equipment. The first frame is pushed under the external production equipment, and the horizontal fine-adjustment platform is moved left and right to accurately align the retracting assembly with the center of the external production equipment. The operation is simple and convenient, and the efficiency of mold replacement is effectively improved.

[0019] The bottom of the first frame 1 is provided with a lifting and bearing assembly 4; a retracting assembly 5 for pulling out the mold is provided on the horizontal fine-tuning platform 2, and a limiting assembly 6 for preventing the mold from sliding out is provided on the horizontal fine-tuning platform 2 on the side away from the trolley 3. When the retracting assembly is precisely aligned with the center of the external production equipment, the lifting and bearing assembly lifts the entire mold changing platform, so that the wheels of the first frame leave the ground, avoiding the first frame from moving when the retracting assembly pulls out the mold, and ensuring the safety of the demoulding process.

[0020] In this embodiment, the horizontal fine-tuning platform 2 includes a horizontal track 2a arranged on the first frame 1, a second frame 2b is arranged on the horizontal track 2a, a hand-cranked drive assembly 2c is arranged at the bottom of the second frame 2b, and the retracting assembly 5 is arranged on the second frame 2b. The hand-cranked drive assembly includes a moving seat arranged at the bottom of the second frame, a screw rod matched with the moving seat is arranged on the first frame, and a gear box, a transmission shaft and a hand-cranked rotating wheel are connected to the screw rod. The specific structure and connection method are prior art and are common knowledge of those skilled in the art, and will not be repeated here.

[0021] In this embodiment, the retracting assembly 5 includes two rows of horizontal roller groups 5a arranged on the horizontal fine-tuning platform 2, a telescopic assembly 5b is arranged between the two rows of horizontal roller groups 5a near one end of the hand push frame 3, a drawing die head 5c matching the mold is arranged at the front end of the telescopic assembly 5b, and a locking latch 5d is arranged on the drawing die head 5c. The telescopic assembly adopts a hand-cranked telescopic chain plate, which is easy to operate, and workers do not need to approach external production equipment to ensure personnel safety. It is also low-cost compared to electric telescopic chains. Its specific structure and connection method are prior art and are common knowledge of those skilled in the art, and will not be repeated here.

[0022] Preferably, an infrared sensor 5e is provided on one side of the locking latch 5d, and an alarm 5f is provided on the telescopic component 5b to cooperate with the infrared sensor 5e. The infrared sensor 5e and the alarm 5f are respectively connected to the control terminal; when the telescopic component 5b starts to work and the locking latch 5d is not locked, the alarm 5f sounds an alarm. During use, the mold and the die head are locked by the locking latch to ensure that the mold does not fall, but during the production process, the operator may sometimes forget to plug the latch. By setting up an infrared sensor and an alarm for monitoring, an alarm is sounded when the latch is not properly plugged in.

[0023] In this embodiment, the lifting load-bearing assembly 4 includes two jack groups 4a symmetrically arranged on both sides of the first frame 1, and a hand-cranked transmission assembly 4b respectively matched with each jack group 4a is provided on the first frame 1. Each jack group includes at least two jacks, and the hand-cranked transmission assembly and each jack corresponding to the same side are driven by a chain. The specific structure and connection method of the hand-cranked transmission assembly are prior art and are common knowledge of those skilled in the art, and will not be repeated here.

[0024] In this embodiment, preferably, the limit assembly 6 includes a mounting seat 6a arranged on the horizontal fine-tuning platform 2, two vertical guide rods 6b are arranged on the mounting seat 6a through a shaft sleeve, and a stopper 6c is arranged at the upper end of the vertical guide rod 6b; a multi-section connecting rod 6d is connected to the lower end of the vertical guide rod 6b, and a foot pedal 6e connected to the multi-section connecting rod 6d is arranged on the side of the first frame 1 located on the hand push frame 3. When the mold is located on the horizontal fine-tuning platform, stepping on the foot pedal causes the vertical guide rod to move upward to block the mold through the stopper to prevent the mold from falling. The specific structure and connection method of the multi-section connecting rod are prior art and are common knowledge of those skilled in the art, and will not be repeated here.

[0025] When in use, push the first frame to the bottom of the external production equipment through the hand pusher, shake the hand crank drive assembly to move the second frame left and right along the horizontal track, align the die head accurately with the center of the external production equipment, turn the hand crank transmission assembly to make the jack lift the frame to the position that matches the mold. Lock the mold and the die head with the locking pin, turn the hand crank telescopic chain plate to pull the mold out of the external production equipment onto the horizontal roller group, and step on the foot pedal to make the block block the mold.

[0026] The above embodiments are preferred implementation modes of the present invention and are only used to facilitate the explanation of the present invention. They are not intended to limit the present invention in any form. Any person with ordinary knowledge in the relevant technical field, if they do not depart from the scope of the technical features of the present invention, can make equivalent embodiments by partial changes or modifications to the technical contents disclosed in the present invention, and they still fall within the scope of the technical features of the present invention without departing from the technical features of the present invention.
