[0002] Injection molding refers to the process of injecting molten plastic into a mold using an injection molding machine, subjecting it to a certain pressure and temperature to completely fill the mold cavity, taking it out after cooling and shaping, and then shearing, trimming and other steps to finally form the desired plastic product. Injection molding is usually used to produce various types of plastic products, including industrial parts, daily necessities, electronic product housings, etc.

[0003] After the injection molded parts are formed, they need to be transferred to the operating equipment or operating table of the next step. This transfer process is generally achieved through a clamp structure.

At the same time, due to the synchronization of the clamp's contraction, there will also be a problem that the rectangular box-shaped injection molded part cannot be clamped.

[0034] An installation frame 10, the installation frame 10 is used to install the moving component 20;

[0035] A moving assembly 20, which is disposed on the mounting frame 10 and is used to realize the movement of the lifting assembly 30;

[0037] A clamping assembly 40, which is disposed on the lifting assembly 30 and is used to clamp the box-shaped injection molded part;

[0038] The clamping assembly 40 includes a connecting frame 400, a sliding rail 401, a pair of sliding blocks 402, a pair of clamping jaws 403 and a pair of first driving members 404. The pair of sliding blocks 402 are respectively arranged in the sliding rail 401 and are slidably connected to the sliding rail 401. A sliding groove 405 is provided at the bottom of the sliding rail 401, and the sliding groove 405 runs through the bottom of the sliding rail 401. A pair of clamping jaws 403 are respectively connected to the pair of sliding blocks 402, and the top of the clamping jaws 403 passes through the sliding groove 405 and is fixedly connected to the sliding blocks 402.

[0039] The arrangement of the sliding block 402 and the sliding track 401 enables the clamping jaw 403 to move only along the sliding track 401 .

[0040] The utility model drives a pair of clamping jaws 403 to approach or move away simultaneously through a pair of first driving members 404, so that the entire clamping jaws 403 can contact the box-shaped injection molded part, thereby increasing the contact area between the clamping jaws 403 and both sides of the box-shaped injection molded part, so that the box-shaped injection molded part can be clamped more stably. Compared with the traditional retractable manipulator clamping jaws 403, the utility model is more suitable for clamping and transferring the box-shaped injection molded part, and has the advantages of stable clamping and the box-shaped injection molded part is not easy to fall. The problem that the current injection molded part clamp cannot effectively clamp the injection molded part when clamping the box-shaped injection molded part, which easily causes the injection molded part to tilt or fall, is solved.

[0041] In order to facilitate the first driving member 404 to drive the clamping, this embodiment is modified on the basis of the above embodiment. The difference from the above embodiment is that the connecting member 406 includes a connecting block 407 and a connecting rod 408, and the connecting block 407 is arranged on one side of the sliding track 401. One end of the connecting block 407 is fixedly connected to the output end of the first driving member 404, and the other end of the connecting block 407 is fixedly connected to one end of the connecting rod 408, and the other end of the connecting rod 408 is fixedly connected to one end of the clamping jaw 403.

[0044] like Figure 4As shown, since the height of the equipment during the processing of the box-shaped injection molded parts may be inconsistent, and the size of the box-shaped injection molded parts is consistent, in order to facilitate the clamping and transfer of different box-shaped injection molded parts, this embodiment is modified on the basis of the above embodiment.

[0045] Preferably, one end of the connecting frame 400 is fixedly connected to the movable mounting seat 305 .

[0046] Preferably, the second driving member 306 is a servo motor. The servo motor can be a servo motor in the prior art that can realize the functions of the utility model.

[0047] When in use, the second driving member 306 drives the threaded rod 303 to rotate, thereby driving the movable mounting seat 305 threadedly connected to the threaded rod 303 to move. In order to prevent the movable mounting seat 305 from rotating with the threaded rod 303, a limiting slider 302 and a vertical slide rail 301 are provided so that the movable mounting seat 305 can only move up and down, thereby realizing the height adjustment of the clamping assembly 40.

[0048] like Figure 5As shown, in order to facilitate the transfer of the box-shaped injection molded parts, this embodiment is modified on the basis of the above embodiment. The difference from the above embodiment is that the moving component 20 includes a moving mounting plate 200, a pair of transverse slide rails 201, a pair of sliding limit blocks 202 and a third driving member 203. The pair of transverse slide rails 201 are fixedly arranged on one side of the moving mounting plate 200, and are respectively located at the upper and lower ends of the moving mounting plate 200. The pair of sliding limit blocks 202 are respectively arranged on the pair of transverse slide rails 201 and are slidably connected to the transverse slide rails 201. The third driving member 203 is fixedly arranged on the other side of the moving mounting plate 200. One side of the lifting mounting plate 300 is fixedly connected to the pair of sliding limit blocks 202. The output end of the third driving member 203 is fixedly connected to the lifting mounting plate 300 for driving the lifting mounting plate 300.

[0049] Preferably, the third driving member 203 is a pneumatic cylinder or a hydraulic cylinder.

[0050] When in use, the lifting and lowering mounting plate 300 is driven by the third driving member 203. In order to realize the movement of the lifting and lowering mounting plate 300, a transverse slide rail 201 and a sliding limit block 202 are set, and then the lifting and lowering mounting plate 300 is fixedly connected to the sliding limit block 202, so that the third driving member 203 drives the lifting and lowering mounting plate 300, and the lifting and lowering mounting plate 300 can move along the transverse slide rail 201.

[0051] The provision of the transverse slide rail 201 and the sliding limit block 202 not only facilitates the installation of the lifting installation plate 300 , but also increases the stability of the lifting installation plate 300 when it moves.

[0052] like Figure 5 As shown, in order to facilitate the installation of the utility model, this embodiment is modified on the basis of the above embodiment. The difference from the above embodiment is that the mounting frame 10 includes a base 100 and a pair of support plates 101, and the pair of support plates 101 are respectively arranged on the base 100, and one end of the pair of support plates 101 is fixedly connected to the base 100, and the other end is respectively fixedly connected to the left and right sides of the movable mounting plate 200.

[0053] The base 100 can be fixedly connected to the ground, so that the utility model can be fixed on the ground, avoiding the problem of tilting or collapsing of the utility model when in use.

[0054] like Figure 3 As shown, in order to further stably clamp the box-shaped injection molded part, this embodiment is modified on the basis of the above embodiment. The difference from the above embodiment is that a pair of clamping jaws 403 are used to clamp the box-shaped injection molded part. One end is provided with a flexible rubber pad 409, and the flexible rubber pad 409 is provided with a plurality of grooves.

[0055] The provision of the flexible rubber pad 409 can not only increase the friction between the clamping jaws 403 and both sides of the box-shaped injection molded part, but also make the clamping jaws 403 fit more closely to both sides of the box-shaped injection molded part during clamping, thereby enabling the clamping jaws 403 to clamp the box-shaped injection molded part more stably.

[0056] Working principle of this utility model:

[0057] The utility model drives a pair of jaws 403 to approach or move away from each other simultaneously through a pair of first driving members 404, so that the entire jaws 403 can be in contact with the box-shaped injection molded part, thereby increasing the contact area between the jaws 403 and both sides of the box-shaped injection molded part, so that the box-shaped injection molded part can be clamped more stably. Compared with the traditional retractable manipulator jaws 403, the utility model is more suitable for the clamping and transfer of box-shaped injection molded parts, and has the advantages of stable clamping and the box-shaped injection molded parts are not easy to fall off.

[0058] The above-mentioned embodiments only express the specific implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
