Description

Door type core pulling mechanism

Technical Field

The utility model relates to the field of dies, in particular to a door type core pulling mechanism.

Background

The vibration friction welding machine utilizes high-frequency vibration to make two plastic parts which are pressed together pass through high-frequency vibration friction until the contact surface of generated friction and shearing heat reaches a fully molten state so as to weld the two plastic parts together. In the production process of the carbon tank, the upper cover and the tank body of the carbon tank are welded through a vibration friction welding machine.

In the vibration friction welding process, core pulling operation is needed, namely, a mold on one side is unfolded to take and put a workpiece, the current core pulling mode is to directly drive one mold to be unfolded in a direction away from the other mold through an air cylinder, namely, front and back core pulling is carried out, but the actual operation is found: the abstract mode reserves larger core pulling space for front and rear positions in the machine, and partial machine has higher space requirement and certain defects when the core pulling is carried out due to insufficient front and rear spaces in the machine.

Disclosure of Invention

Aiming at the defects of the prior art, the utility model provides a door type core pulling mechanism, which solves the problems in the background technology.

In order to achieve the above purpose, the utility model is realized by the following technical scheme: the door type core pulling mechanism comprises a cylinder, wherein one end of the cylinder provided with a piston rod is hinged with two first fixing blocks which are arranged up and down, a second fixing block is fixed between the back surfaces of the two fixing blocks, an installation block is hinged on the second fixing block, and an edge lug is arranged on the front surface of the installation block;

and a piston rod of the air cylinder is connected with a pull block, and the pull block is hinged with the side lug.

Further limited, the door type core pulling mechanism is characterized in that a rectangular opening is formed in the end portion of the pulling block, and the side lug is located in the rectangular opening.

Further limited, in the door type core pulling mechanism, the mounting block is provided with a mounting hole, and the mounting hole adopts a counter bore.

Further limited, the door type core pulling mechanism is characterized in that the second fixing block is connected with the first fixing block through bolts.

The utility model has the following beneficial effects: according to the utility model, the die needing core pulling is arranged on the mounting block, and the cylinder can be arranged at the side surface position of the machine through the matching of the plurality of connecting rod mechanisms, so that the rotary core pulling is realized, the structure is simple, the occupation of the space in the front-back direction of the machine is reduced, and the problem of insufficient front-back space in the machine is solved.

Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Referring to fig. 1-2, the present utility model provides a technical solution: the utility model provides a door-type core pulling mechanism, including cylinder 1, cylinder 1 is equipped with two fixed blocks one 2 that the one end of piston rod 3 articulates has the upper and lower setting, and pull piece 4 is installed to the tip of piston rod 3, and rectangular opening has been seted up to the tip of pull piece 4, installs fixed block two 7 through the bolt between the back of two fixed blocks, is equipped with the breach on the fixed block two 7, articulates in the breach has installation piece 6, has seted up the mounting hole on the installation piece 6, and the mounting hole adopts the counter bore for through the mould that the bolt installation needs to loose core, the front of installation piece 6 is equipped with limit ear 5, limit ear 5 articulates with the rectangular opening of pull piece 4.

As shown in figure 3, when the cylinder 1 is in operation, the die which needs to be pulled out is arranged on the mounting block 6 through bolts, the die is in a closed state, as shown in figure 3, when the die is required to be pulled out, the piston rod 3 of the cylinder 1 pulls the pulling block 4 to drive one end of the mounting block 6 to rotate along the rotating shaft on the lug 5, the other end of the cylinder rotates along the rotating shaft on the fixing block II 7, and finally the die is opened by ninety degrees, in the process, the fixing block I2 rotates along the rotating shaft on the cylinder 1, the mounting block 6 rotates along the rotating shaft on the fixing block II 7, and the lug 5 rotates along the rotating shaft on the pulling block 4, so that the pulling block 4 and the piston rod 3 always keep moving forwards and backwards, and the extension of the piston rod 3 can not be blocked.

According to the utility model, the die needing core pulling is arranged on the mounting block 6, and the cylinder 1 can be arranged at the side surface position of the machine through the matching of the plurality of connecting rod mechanisms, so that the rotary core pulling is realized, the structure is simple, the occupation of the space in the front-back direction of the machine is reduced, and the problem of insufficient front-back space in the machine is solved.
