Description

Technical Field

[0001] The utility model belongs to the technical field of in-mold injection molding, in particular to an in-mold injection molding metal inlay fixture. Background Art

[0002] A fixture is a large category of tools for carpentry, ironwork, fitter, machinery, electronic control and some other handicrafts. It is mainly used as a tool to assist in controlling position or movement. The fixture can be divided into three categories: process assembly fixtures, project test fixtures and circuit board test fixtures.

[0003] With the continuous improvement of injection molding technology, more and more technical fields have begun to use injection mold technology. For example, many small rod-shaped or columnar parts are involved in the automobile manufacturing industry. The traditional processing technology is time-consuming and labor-intensive. The injection molding process can well avoid this shortcoming. However, the rod-shaped or columnar parts have different lengths and shapes. Designing molds one by one will reduce practicality. Therefore, it is necessary to add inserts in the mold cavity so that the same mold cavity can be suitable for injection molding of different parts with the cooperation of the inserts. However, in fact, the mold cavity of rod-shaped or columnar parts has the characteristics of small aperture and large depth. It is not easy to take out the inserts after they are placed in the mold cavity. Moreover, some inserts need to be split into multiple standard monomers and assembled into inserts in order to be separated from the molded parts. This results in the need to repeatedly assemble the inserts when continuously injecting multiple parts, which greatly reduces the processing efficiency. Therefore, it is necessary to develop a new type of metal insert fixture for injection molding that is easy to pick up and efficient to avoid the shortcomings of the existing technology.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] like Figures 1 to 5 As shown, the utility model provides an in-mold injection metal inlay fixture, comprising a mold 1, a mold cavity 2 is opened on the top of the mold 1, an inlay 3 is placed inside the mold cavity 2, and a control component 4 is arranged inside the mold 1 and located below the mold cavity 2;

[0025] The control assembly 4 includes an operating member 41 movably installed inside the mold 1, and two left and right adjusting members 42 are arranged inside the operating member 41;

[0026] The operating member 41 includes an operating shaft 411 rotatably sleeved inside the mold 1, a mounting column 412 is fixedly sleeved on the middle part of the operating shaft 411, and the upper and lower ends of the mounting column 412 extend to the upper and lower sides of the operating shaft 411, the tops of the operating shaft 411 and the mounting column 412 are flush with the bottom of the inner cavity of the mold cavity 2, and the bottoms of the operating shaft 411 and the mounting column 412 protrude to the lower end of the inner cavity of the mold cavity 2; the upper and lower ends of the mounting column 412 are respectively fixedly installed with a first magnet 415 and a second magnet 416; due to the setting of the operating shaft 411, the alternation of its upper and lower ends can achieve the effect of pushing the insert 3, so that it is originally loosened from the inside of the mold cavity 2, and then under the repulsive action of the second magnet 416, it is quickly ejected to the outside of the mold 1, so that it is convenient for the staff to take and place it.

[0027] like Figure 5 As shown, a third magnet is disposed at the bottom of the insert 3 , the bottom of the third magnet and the outer end of the first magnet 415 attract each other, and the bottom of the third magnet and the outer end of the second magnet 416 repel each other.

[0028] like Figure 1 and Figure 5 As shown, both ends of the operating shaft 411 are fixedly connected with a linkage shaft 413 , and the far ends of the two linkage shafts 413 are fixedly connected with a control knob 414 , and the control knob 414 is movably embedded in the left and right sides of the mold 1 .

[0029] like Figure 5 As shown, the adjusting member 42 includes a sliding cavity 421 opened inside the operating shaft 411 and the left and right linkage shafts 413, the sliding cavity 421 is movably sleeved with an adjusting piston 422, the cross-sections of the inner wall of the sliding cavity 421 and the outer surface of the adjusting piston 422 are both polygonal, the outer surface of the adjusting piston 422 is fixedly connected to a linkage sleeve 423 on the side away from the operating shaft 411, the internal thread sleeve of the linkage sleeve 423 is sleeved with an adjusting rod 424, and a section of the adjusting rod 424 away from the operating shaft 411 extends to the linkage sleeve A connecting rod 425 is fixedly connected to the outside of 423, and another section of the connecting rod 425 extends to the outside of the control knob 414 and is fixedly connected to the adjusting knob 426, and the connecting rod 425 is movably sleeved inside the control knob 414; due to the cooperation between the sliding cavity 421 and the adjusting piston 422, the rotation of the linkage sleeve 423 can be avoided, and then when the adjusting rod 424 is rotated by the adjusting knob 426 and the connecting rod 425, the linkage sleeve 423 can be driven to move left and right, thereby driving the adjusting piston 422 to move left and right.

[0030] like Figure 5As shown, a limiting cavity 427 is provided inside the installation column 412, and a positioning communicating groove 428 is also provided inside the installation column 412 at the bottom of the limiting cavity 427. The limiting cavity 427 and the positioning communicating groove 428 are connected to each other, and the inner diameter of the limiting cavity 427 is larger than the inner diameter of the positioning communicating groove 428. Due to the setting of the positioning communicating groove 428, it can ensure that the communicating hole 430 can be connected with the limiting cavity 427 through the positioning communicating groove 428, and it can also avoid the situation where the lower end of the linkage plunger 429 moves to the positioning communicating groove 428 to block the communicating hole 430.

[0032] like Figure 5 As shown, two left and right communicating holes 430 are opened inside the operating shaft 411, and the proximal ends of the two communicating holes 430 are respectively connected to the left and right sides of the inner cavity of the positioning communicating groove 428, and the distal ends of the two communicating holes 430 are respectively connected to the proximal ends of the left and right sliding cavities 421.

[0033] The working principle and use process of this utility model:

[0034] Rotating any one of the left and right control knobs 414 can drive the control shaft 411 to rotate through the corresponding linkage shaft 413. Since the rotation of the control shaft 411 can drive the upper and lower first magnets 415 and the second magnet 416 to move through the mounting column 412, the upper and lower positions of the first magnet 415 and the second magnet 416 can be exchanged. When the first magnet 415 is located at the top, the top of the control shaft 411 and the mounting column 412 are flush with the bottom of the inner cavity of the mold cavity 2 and will not conflict with the insert 3. Moreover, under the magnetic attraction of the first magnet 415, the insert 3 can be firmly placed at the bottom of the mold cavity 2; and when the second magnet 416 is located at the top, the top of the control shaft 411 and the mounting column 412 protrudes from the lower end of the inner cavity of the mold cavity 2, and while conflicting and pushing the insert 3, the insert 3 is ejected to the outside of the mold 1 due to the repulsive effect of the second magnet 416, thereby achieving the purpose of conveniently and quickly removing the insert 3 from the narrow space of the mold cavity 2.

[0035] After the insert 3 is correctly placed, rotating any one of the left and right adjustment knobs 426 can drive the corresponding adjustment rod 424 to rotate through the connecting rod 425, and then the adjustment piston 422 is moved along the inside of the sliding cavity 421 with the cooperation of the sliding cavity 421 and the linkage sleeve 423, so that the air pressure inside the sliding cavity 421 can be changed, and then the air pressure inside the limit cavity 427 is changed with the cooperation of the connecting hole 430 and the positioning connecting groove 428, so that the linkage plunger 429 can be moved up and down, and then the first magnet 415 and the insert 3 adsorbed on the top thereof can be driven up and down, so that the actual injection height of the top of the insert 3 in the mold cavity 2 is changed, so that it is suitable for injection molding of column structures of different specifications.
