DETAILED DESCRIPTION

[0027] In order to further understand the features, technical means and specific purposes and functions achieved by the utility model, the utility model will be described in further detail below in combination with the drawings and specific embodiments.

[0028] Referring to Figure 1 As shown in the figure, a mold suction mechanism of a mold clamping machine capable of preventing finished product demolding deformation comprises a machine body 1, further comprises a lifting device 2 and a guiding device 3 arranged at the machine body 1, and the bottom of the lifting device 2 and the upper portion of the guiding device 3 are both provided with an electric permanent magnetic disc body 4.

[0029] It should be noted that in use, the upper mold is first placed on the upper side of the electric permanent magnetic disc body 4 at the bottom, and the electric permanent magnetic disc body 4 above is moved according to the specified route through the linear guide rail in the guiding device 3 until the electric permanent magnetic disc body 4 is moved to the position directly below the electric permanent magnetic disc body 4 installed at the bottom of the lifting device 2, and then the electric permanent magnetic disc body 4 installed at the bottom of the lifting device 2 is driven to descend to the position in contact with the top of the upper mold through the pushing of the hydraulic cylinder in the lifting device 2. At this time, the electric permanent magnetic disc body 4 installed at the bottom of the lifting device 2 starts to magnetically attract the upper mold, and then the lower mold is placed on the electric permanent magnetic disc body 4 above the guiding device 3 for magnetic attraction.

[0030] Referring to Figure 1 and Figure 2 As shown in the figure, further comprises a clamping mechanism 5 arranged around the electric permanent magnetic disc body 4; the electric permanent magnetic disc body 4 is concavely provided with a mounting groove, the mounting groove is cross-shaped and the four extension portions of the cross-shaped mounting groove are all provided in an open manner, and the four clamping mechanisms 5 are respectively located at the four extension portions of the mounting groove and can slide along the extension direction of the corresponding extension portion.

[0031] It should be noted that the arrangement of the four clamping mechanisms 5 can push and adjust the position of the mold magnetically attracted from four directions, so as to better ensure that the mold can be smoothly centered and attracted.

[0032] Referring to Figure 2 , Figure 5 and Figure 6As shown, the inner wall of the mounting groove is provided with four magnetic isolation plates 4a, and the middle part of the mounting groove is provided with a transverse traction plate 4b and a longitudinal traction plate 4c which can move along the depth direction of the mounting groove. The end of each transverse traction plate 4b and longitudinal traction plate 4c is hinged with an adjusting arm 4d between the clamping mechanism 5 at the corresponding end of the mounting groove.

[0033] It should be noted that when magnetic adsorption is performed, the electric permanent magnetic disk body 4 will simultaneously perform magnetic adsorption on the transverse traction plate 4b and the longitudinal traction plate 4c, thereby driving the transverse traction plate 4b and the longitudinal traction plate 4c to move along the depth direction of the mounting groove, and then pulling the clamping mechanism 5 through the adjusting arm 4d to clamp the four sides of the mold. The setting of the magnetic isolation plate 4a is to avoid the magnetic force at the side wall of the mounting groove from interfering with the transverse traction plate 4b and the longitudinal traction plate 4c.

[0034] The working principle of the electric permanent magnetic disk body 4 is that two permanent magnets are usually used as magnetic sources inside the electric permanent magnetic disk body 4. It relies on instantaneous pulse current to control the change of magnetic pole direction, so that the magnet reaches the state of having magnetism or no magnetism. When the electromagnetic system is instantaneously connected with a forward excitation current, the N and S poles of the reversible polarity magnetic steel will become consistent with the N and S poles of the irreversible polarity magnetic steel. At this time, the electric permanent magnetic disk body 4 shows magnetism to the outside and can adsorb the mold. When the electromagnetic system is instantaneously connected with a reverse excitation current, the N and S poles of the reversible polarity magnetic steel will become opposite to the N and S poles of the irreversible polarity magnetic steel. At this time, the magnetic force lines of the two types of magnetic steel are closed, and the entire magnetic force device is in a non-magnetic state.

[0035] Referring to Figures 4-6 As shown, the clamping mechanism 5 includes a sliding block 5a and a positioning bolt 5b. The magnetic isolation plate 4a is horizontally provided with a guide groove matched with the sliding block 5a along the extension direction of the extension part. The end of each adjusting arm 4d is hinged with the sliding block 5a on the adjacent side. Each magnetic isolation plate 4a is provided in an "L" shape.

[0036] It should be noted that the part of the clamping mechanism 5 mainly connected with the adjusting arm 4d is the sliding block 5a, and the guide groove is provided to facilitate the sliding of the sliding block 5a along the guide groove to clamp the mold, so as to ensure the accuracy of the clamping effect and the clamping direction.

[0037] Referring to Figures 2-5 As shown, the transverse extension part of the mounting groove is symmetrically provided with a connecting assembly 4e about the vertical plane where the symmetry axis is located. The middle part of the mounting groove is provided with a guide rod 4f. The connecting assembly 4e and the guide rod 4f are both vertically arranged, and the top of the connecting assembly 4e and the guide rod 4f is connected with the inner wall of the top of the mounting groove.

[0038] The transverse traction plate 4b is provided with a connecting groove matched with the connecting assembly 4e, and the middle part of the transverse traction plate 4b and the longitudinal traction plate 4c is provided with a vertical groove matched with and penetrated by the guide rod 4f.

[0039] It should be noted that the connecting assembly 4e is a connecting rod connected with a thread at the bottom and a nut matched with the thread at the outer side, and when installed, the connecting groove at the transverse traction plate 4b is butted with the connecting rod, and the nut is locked by the thread.

[0040] Referring to FIGS. 4 and 5, Figure 3 、 Figure 5 and Figure 7 , the longitudinal traction plate 4c is further provided with a reset spring 4c1 between the longitudinal traction plate 4c and the inner wall of the installation groove.

[0041] It should be noted that the reset spring 4c1 is a component for pushing the transverse traction plate 4b and the longitudinal traction plate 4c to reset after the magnetic attraction of the electric permanent magnetic disk body 4 disappears. The recesses at the transverse traction plate 4b and the longitudinal traction plate 4c are used to compress the thickness of the two as much as possible in the limited space, so as to increase the vertical moving distance of the two, thereby improving the clamping distance of the clamping mechanism 5.

[0042] Referring to FIGS. 4 and 5, Figure 2 and Figure 5 , the length extension direction of the transverse traction plate 4b is the same as the width extension direction of the electric permanent magnetic disk body 4, the length extension direction of the longitudinal traction plate 4c is the same as the length extension direction of the electric permanent magnetic disk body 4, and the width of the transverse traction plate 4b and the longitudinal traction plate 4c is the same and is the shortest distance between the adjacent two magnetic separation plates 4a.

[0043] Referring to FIGS. 4 and 5, Figures 3-6 , the bottom of the sliding block 5a is provided with a clamping block 5c extending along the length direction of the sliding block 5a, and the sliding block 5a is further vertically recessed with an adjusting cavity, and the adjusting cavity extends along the width direction of the sliding block 5a to form a positioning groove matched with the positioning bolt 5b.

[0044] The clamping block 5c vertically extends into the adjusting cavity to form a plug-in part, and a plurality of through holes for the positioning bolt 5b to penetrate are vertically and equidistantly provided in the plug-in part.

[0045] It should be noted that in use, the positioning bolt 5b is rotated until it is disengaged from the insertion of the through hole, and then the insertion depth of the clamping block 5c and the sliding block 5a can be adjusted, so that the clamping block 5c is adjusted to the appropriate clamping height. At the same time, the adjustment of the clamping mechanism 5 by the positioning bolt 5b facilitates the convenient replacement of each component in the clamping mechanism 5.

[0046] The above embodiments only express one or several embodiments of the present application, and the description is more specific and detailed, but it should not be understood as a limitation on the scope of the present application. It should be noted that for ordinary skilled persons in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which are all within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the appended claims.
