[0029] Embodiment 1

[0030] Referring to Figure 1 , Figure 2 and Figure 3 , a high-frequency machine sliding block mechanism comprises a gantry sliding frame 1, a position adjusting device 2, a sliding seat 3 and a rigid connecting piece 5.

[0031] The door type sliding frame 1 is mainly composed of two parallel sliding rails 11, an upper beam 12 and a lower beam 13. The two parallel sliding rails 11, the upper beam 12 and the lower beam 13 form a "door opening" shape. The specific door opening shape is shown in Figure 2 The door type sliding frame 1 is mainly composed of two parallel sliding rails 11, an upper beam 12 and a lower beam 13. The two parallel sliding rails 11, the upper beam 12 and the lower beam 13 form a "door opening" shape. The specific door opening shape is shown in

[0032] The position adjusting device 2 is mainly composed of a lead screw 21, a lifting nut 22 and a pressing device. The upper end of the lead screw 21 is assembled on the upper beam 12 of the door type sliding frame. The lifting nut 22 is assembled on the middle end of the lead screw 21. The lower end of the lead screw 21 is optionally sleeved on a central positioning plate 23 for positioning the center of the lead screw and improving the appearance. The lifting nut is in transmission connection with the pressing device for adjusting the position of the door type sliding frame and / or for moving the door type sliding frame up and down and transmitting the pressure of the pressing device. The initial position of the lifting nut assembled on the lead screw is adjustable. In a specific embodiment, the upper beam is provided with a lead screw locking device which can adjust the initial position of the lifting nut assembled on the lead screw and lock and maintain the adjusted position. Thus, the lead screw locking device can be used to lock and maintain the position adjusted by the lifting nut. The lower beam adjusts the horizontal state of the mold through a plurality of horizontal adjusting screws. For example, four horizontal adjusting screws are arranged at the front and rear left and right points to adjust the horizontal state of the mold through the four horizontal adjusting screws. In a specific embodiment of the pressing device, the pressing device includes a rocker arm 24 and a fulcrum 25 fixed on the support 4. The rocker arm 24 and the fulcrum 25 form a lever structure with a lever principle. One end of the rocker arm 24 is fixedly assembled with the lifting nut. The other end of the rocker arm is fixed with a power device, for example, a pneumatic cylinder or a manually powered device. The power device provides power at the other end of the rocker arm to realize the pressing of the lifting nut through the lever principle.

[0033] The sliding seat 3 is mainly composed of a guide sleeve group assembled on the frame 4. The guide sleeve group is in slidable sleeve joint with the two parallel sliding rails of the door type sliding frame for cooperating to realize the up and down sliding of the door type sliding frame. The guide sleeve group is composed of a plurality of guide sleeves. The guide sleeves are self-lubricating guide sleeves. There are commercially available self-lubricating guide sleeves without oil. The cooperation of the guide sleeves and the sliding rails can realize the self-lubricating sliding without oil. In a first specific embodiment, the guide sleeve group is composed of two parallel long guide sleeves. One long guide sleeve is sleeved on each sliding rail for slidable joint. In a second specific embodiment, the guide sleeve group is composed of four short guide sleeves 31. Two short guide sleeves 31 are sleeved on each sliding rail 11 for up and down slidable joint. The second specific embodiment is preferred in the present embodiment.

[0034] The rigid connecting piece 5 is fixed at one end on the upper beam 12 and at the other end on the lower beam 13 to form a rigid connection between the upper beam and the lower beam and make the door type sliding frame a high rigidity structure.

[0035] The number of rigid connectors is not limited, and the number of rigid connectors is not less than 1, which can be 1, 2, or theoretically more than 3. Generally, only 1 can solve the problem, but it can also be 2.

[0036] The specific shape of the rigid connector is not limited, and the preferred rigid connector is a columnar rigid connector. The rigid connector 5 forms the side edges of the prism with the two parallel sliding rails 11.

[0037] In this embodiment, the rigid connector is a columnar rigid connector. In this way, the columnar rigid connector 5 forms three side edges of the triangular prism with the two parallel sliding rails 11, making the door-type sliding frame a high-rigidity structure.

[0038] As a specific embodiment, the two parallel sliding rails and the columnar rigid connector form a triangular distribution structure in the top view of their cross section. That is, the rigid connector is preferably arranged on the rear end between the two parallel guide rails.

[0039] As a specific embodiment, one end of the rigid connector 5 is welded or threaded to the upper beam 12, and the other end of the rigid connector 5 is welded or threaded to the lower beam 13. Of course, in addition to welding or threading, there can be other fixing methods, which are not listed one by one.

[0040] As a specific embodiment, the rigid connector 5 is a rigid connector made of metal material. Of course, the metal material is not limited to metal material.

[0041] In one specific embodiment, the high-frequency machine slider device further includes a rigid connector, the upper end of the rigid connector is fixed to the upper beam, and the lower end of the rigid connector is fixed to the lower beam, so that the upper beam and the lower beam are rigidly connected. One of the rigid connectors forms three side edges of a triangular prism with the two parallel sliding rails, the upper beam forms the top surface of the triangular prism, and the lower beam forms the bottom surface of the triangular prism, so that the upper beam, the lower beam, the left and right two parallel sliding rails, and the columnar rigid connector form a triangular prism structure, greatly improving the rigidity and stability of the entire structure, preventing load deviation, and reducing instability of tilting.

[0042] The door-type sliding frame in the prior art is a one-sided structure, so the lower beam still has tilting instability, the entire structure is not rigid enough, and deviation will occur. By adding the rigid connector, the structure of the door-type sliding frame becomes a three-dimensional triangular prism structure, and the three triangular positions of the lower beam are respectively limited by the two parallel sliding rails and the columnar rigid connector, greatly improving the stability of the lower beam and preventing load deviation and tilting.

[0043] When working, the power device provides power to press the lifting nut through the lever principle, and then drives the three-dimensional triangular prism to move up and down, the lower beam fixes the mold, thereby driving the mold to move up and down to complete the work. The three-dimensional triangular prism bears the functions of guiding, reciprocating up and down, lifting adjustment and pressure transmission in the high-frequency machine slider mechanism, and has the advantages of the portal sliding frame and overcomes the shortcomings of the portal sliding frame.

[0044] In this embodiment, when the three-dimensional triangular prism is pressed downward, the screw rod pulls the upper beam downward, the upper beam is pulled by the force and transmits the force to the lower beam through the two side rails and the rigid connecting piece to press downward, and the screw rod is in a tensile state.

[0045] Embodiment 2

[0046] With reference to Embodiment 1, different from Embodiment 1, the lower beam of this embodiment can also adjust the horizontal state of the mold by setting a horizontal cross frame.

[0047] Embodiment 3

[0048] With reference to Embodiment 1, different from Embodiment 1, as shown in Figure 4 , the upper end of the screw rod is fixed on the upper beam of the portal sliding frame, and the lower end of the screw rod is inserted into the through hole or groove 14 of the lower beam without fixation, so that the screw rod 21 is in a vertical state. That is, the lower end of the screw rod is limited in the through hole or groove of the lower beam without fixation, when the rocker arm is pressed downward, the screw rod transmits the pressure generated by the pressing device to the upper beam, at the same time, the lower beam plays the role of the original center positioning plate to position the center of the screw rod.

[0049] Embodiment 4

[0050] With reference to Embodiment 1, different from Embodiment 1, the screw rod of this embodiment is fixedly connected to the lower beam of the portal sliding frame to replace the screw rod fixedly connected to the upper beam of the portal sliding frame, so as to change the force applying mode.

[0051] In Embodiment 1, when the three-dimensional triangular prism is pressed downward, the screw rod pulls the upper beam downward, the upper beam is pulled by the force and transmits the force to the lower beam to press downward, and the screw rod generates a pulling force on the upper beam; in this embodiment, when the three-dimensional triangular prism is pressed downward, the screw rod directly presses the lower beam downward, and the lower beam is directly pressed downward by the extrusion force of the screw rod. The screw rod directly generates an extrusion force on the lower beam.

[0052] The effect of the pulling force of Embodiments 1-3 is better than that of the extrusion force of Embodiment 4, because compared with the extrusion state of the screw rod of Embodiment 4, the screw rod of Embodiments 1-3 is in a tensile state, and is not easy to deform and damage.

[0053] Embodiment 5

[0054] With reference to the embodiment 1, different from the embodiment 1, the lead screw of the present embodiment is not only fixedly connected to the upper beam of the portal sliding frame, but also fixedly connected to the lower beam of the portal sliding frame.

[0055] Embodiment 6

[0056] With reference to the embodiment 1, different from the embodiment 1, as shown in Figure 5 The two columnar rigid connecting members 5 form four side edges of a quadrangular prism with the two parallel sliding tracks 11, and each rigid connecting member is fastened at one end to the upper beam and at the other end to the lower beam, so that the upper beam and the lower beam are rigidly connected and the portal sliding frame has a high rigidity.

[0057] It should be noted that in some modified embodiments, for example, three columnar rigid connecting members are used to make a triangular prism into a pentagonal prism, but such modifications should also be within the protection scope of the present utility model.

[0058] It should be noted that the purpose of adding the rigid connecting members to the portal sliding frame is to rigidly connect the upper beam and the lower beam so that the portal sliding frame has a high rigidity, and therefore the rigid connecting members are not limited in shape and can be U-shaped, H-shaped, L-shaped, etc., or other special shapes, as long as the purpose is to rigidly connect the upper beam and the lower beam, which should be within the protection scope of the present utility model.

[0059] For example, although one rigid connecting member is used, the structure of the rigid connecting member is made more complex, such as also using a guide sleeve cooperation mode, i.e. the rigid connecting member is changed into a third parallel sliding track. Since there are already two parallel sliding tracks, a third sliding track can not be needed, but the present utility model does not exclude such modifications, which should also be within the protection scope of the present utility model.

[0060] The term "middle end" means the middle end, i.e. a part or position in the middle.

[0061] The above series of detailed descriptions are only specific descriptions of the feasible embodiments of the present utility model, and are not used to limit the protection scope of the present utility model, and any equivalent embodiments or modifications made without departing from the spirit of the present utility model should be included in the protection scope of the present utility model.
