In addition, the terms "first" and "second" are only used for distinction in description and have no special meanings.

[0035] For Figure 1 the working conditions shown, this preferred embodiment provides a carrier core filling and pressing mold. Please refer to Figures 3 to 7 shown in the figure, which includes a support base 1, a carrier positioning and guiding mechanism 2, a cylinder positioning mechanism 3, and a cylinder fixing mechanism 4, where:

[0036] A vertical plate 11 is provided on the support base 1;

[0037] The carrier positioning and guiding mechanism 2 includes a guiding cylinder 21 fixed on the vertical plate 11. The axes of the guiding cylinders 21 are horizontally arranged, and the carrier 5 to be installed passes through the inner wall of the guiding cylinder 21.

[0038] The cylinder positioning mechanism 3 includes a fixed cylinder 31 connected and communicated with one end of the guiding cylinder 21. A positioning plate 32 is provided on the end face of the non-connected end of the fixed cylinder 31. An annular positioning convex edge 321 is provided on the positioning plate 32. A fixed bracket 33 is provided on the outer surface of the fixed cylinder 31. The fixed bracket 33 is used to support the cylinder 6 to be installed, so that the cylinder opening of the cylinder 6 abuts against the positioning plate 32, and the annular positioning convex edge 321 forms an inner limit for the cylinder opening of the cylinder 6, so that the cylinder 6, the guiding cylinder 21 and the fixed cylinder 31 are all located on the same axis;

[0039] The cylinder fixing mechanism 4 includes a plurality of clamping blocks 41 that are circumferentially distributed around the annular positioning convex edge 321 and can move radially along the positioning plate 32. Each clamping block 41 acts on the outer surface of the cylinder 6 together, so that the cylinder 6 is clamped and fixed.

[0040] Thus, through the carrier positioning and guiding mechanism 2, the carrier 5 is kept in an accurate position during the press-fitting process to avoid deformation of the carrier 5; through the cylinder positioning mechanism 3, the cylinder 6 and the carrier 5 are coaxially placed to avoid the influence of the machining error of the outer shape of the cylinder 6; through the cylinder fixing mechanism 4, the position of the cylinder 6 is locked, and then the carrier 5 is pushed to move towards the cylinder 6, so that the carrier 5 can be smoothly and accurately inserted into the cylinder 6, ensuring the assembly consistency, and reducing the surface damage of the cylinder 6 and the carrier 5 during the clamping, positioning and assembly processes, reducing the labor intensity of workers, and improving the production efficiency.

[0041] Specifically, the cylinder fixing mechanism 4 further includes a driving plate 42 sleeved on the fixed cylinder 31 and abutted against the positioning plate 32. The driving plate 42 can rotate relative to the positioning plate 32. Eccentric arc-shaped grooves 421 corresponding to each clamping block 41 are provided on the driving plate 42. Radial straight grooves 322 corresponding to each clamping block 41 are provided on the positioning plate 32. A cam bearing 43 that sequentially penetrates into a radial straight groove 322 and an eccentric arc-shaped groove 421 is provided on each clamping block 41. For details, see Figure 6 , thus, the rotational movement of the driving plate 42 is converted into the radial movement of each clamping block 41 to realize the clamping and releasing functions of the carrier 5.

[0042] Furthermore, a driving cylinder 44 is provided on the fixed bracket 33. A transmission connection block 45 is provided between the output rod of the driving cylinder 44 and the driving plate 42, so as to simply control the forward and reverse rotation of the driving plate 42 relative to the positioning plate 32.

[0043] Particularly, a limiting step 311 is provided on the fixed cylinder 31. A cushion block 46 abutted against the limiting step 311 is sleeved on the fixed cylinder 31. The driving plate 42 is clamped between the cushion block 46 and the positioning plate 32, so that the driving plate 42 can only rotate, ensuring the structural stability.

[0044] Furthermore, the clamping blocks 41 are fan-shaped, and the clamping blocks 41 are equidistantly spaced. The cylinder fixing mechanism 4 further includes a guiding pressing block 47 located between two adjacent clamping blocks 41. Each guiding pressing block 47 is fixed to the positioning plate 32, and pressing grooves 471 are respectively arranged on both sides of the guiding pressing block 47. Pressing edges 411 are respectively arranged on both sides of the clamping block 41 and are matched with the pressing grooves 471, so as to ensure that the reciprocating movements of the clamping blocks 41 always maintain accurate positions, and improve the fixing effect on the cylinder 6.

[0045] Particularly, the positioning plate 32 is annular. The inner surface of the inner ring of the positioning plate 32 is flush with the inner wall surface of the guiding cylinder 21. An annular positioning convex edge 321 is formed at the inner ring opening of the positioning plate 32 and forms a slope surface for guiding the cylinder 6 to accurately reach the position. Even if there is a large deviation between the initial position and the target position of the cylinder opening of the cylinder 6, under the guidance of the slope surface, when the cylinder opening of the cylinder 6 finally abuts against the positioning plate 32, the coaxiality of the cylinder 6 and the carrier 5 is improved, and during the subsequent process of the clamping blocks 41 pushing towards the center against each other, the position accuracy of the cylinder 6 can be further improved to meet the assembly requirements.

[0046] Specifically, the cylinder positioning mechanism 3 further includes a supporting block 34. The supporting block 34 is driven by an additional device and is used to lift one end of the cylinder 6 that does not abut against the positioning plate 32, so as to cooperate with the fixing bracket 33 to make the axis of the cylinder 6 horizontal, and avoid the non-abutting end of the cylinder 6 from tilting and affecting the loading effect of the carrier 5.

[0047] Specific operation process:

[0048] 1) Each clamping block 41 is in an initial open state. The cylinder 6 to be installed is placed horizontally on the fixing bracket 33 through an additional device, and the levelness of the cylinder 6 is adjusted through the supporting block 34, and the cylinder 6 is made to lean towards the positioning plate 32. Under the action of the annular positioning convex edge 321, the position of the cylinder 6 is basically determined;

[0049] 2) The driving cylinder 44 drives the driving plate 42 to rotate, and then drives each clamping block 41 to move towards the center, so as to clamp and fix the cylinder 6. At this time, it is ensured that the cylinder 6 fits against the positioning plate 32, and the attitude of the cylinder 6 is coaxial with the guiding cylinder 21 and the fixing cylinder 31 to ensure the stability and smoothness of pressing into the carrier 5;

[0050] 3) The carrier 5 to be installed is put into the guiding cylinder 21 through an additional device, and the carrier 5 is pushed towards the cylinder 6. The carrier 5 moves along the guiding cylinder 21 and the fixing cylinder 31, passes through the positioning plate 32, and finally is loaded into the cylinder 6;

[0051] 4) After the carrier 5 is completely pressed into the cylinder 6, it is confirmed that the carrier 5 is pressed in place and does not fall off, and the cylinder 6 is not cracked. Then, the driving cylinder 44 can be controlled to drive the clamping blocks 41 to reset, and the pressed product is taken out, and the next pressing process is repeated.

[0052] Obviously, the above embodiments of the present utility model are merely examples for clearly illustrating the present utility model, rather than limitations on the implementation manners of the present utility model. For those of ordinary skill in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present utility model. It is not necessary and impossible to enumerate all implementation manners here. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present utility model shall be included within the protection scope of the claims of the present utility model.
