Detailed Description

The present application is described in further detail below with reference to the attached drawings.

The embodiment of the application discloses a composite compression mold structure. Referring to fig. 1 and 2, the composite die structure includes a frame 1, and a top plate 11, a turnover plate 12, a bearing plate 13, a lower die 14, a middle die 15, and an upper die 16 are disposed on the frame 1. The top plate 11 is connected with the frame 1 in a vertical sliding mode, the bearing plate 13 is fixedly connected with the frame 1, and the turning plate 12 is connected with the frame 1 in a rotating mode. A carrier plate 13 is disposed between top plate 11 and flap 12, and a lower die 14 is disposed on carrier plate 13. Still be provided with two jacking strips 131 on loading board 13, two jacking strips 131 set up the relative both sides at lower mould 14 to two jacking strips 131 with bear the vertical connection that slides of seat. The middle mold 15 is provided on two jacking bars 131, and a distance between the middle mold 15 and the lower mold 14 is changed by vertical sliding movement of the two jacking bars 131. Be provided with lift post 111 on roof 11, lift post 111 can with jacking strip 131 butt at roof 11's vertical slip in-process to drive jacking strip 131 and well mould 15 vertical migration, make well mould 15 and lower mould 14 separation. The upper die 16 is provided on the flap 12, and the upper die 16 can abut against the middle die 15 by rotation of the flap 12.

The frame 1 may further be provided with a driving device for driving the top plate 11 to vertically slide on the frame 1 and driving the turning plate 12 to turn over on the frame 1, so that the upper die 16, the middle die 15 and the lower die 14 are pressed against or separated from each other. In this embodiment, a linkage plate (not shown) is further disposed on the frame 1 in a vertically sliding manner, and the linkage plate can respectively abut against the turning plate 12 and the top plate 11. Specifically, when the driving device drives the linkage plate to move towards the turning plate 12, the upper end of the linkage plate is firstly abutted against the turning plate 12. Because the turning plate 12 is rotationally connected with the frame 1, the turning plate 12 is turned and opened under the abutting action force of the linkage plate. In the process of turning over and opening the turning plate 12, the lower end part of the linkage plate is abutted against the top plate 11 to drive the top plate 11 to move upwards, so that the jacking strip 131 and the middle die 15 are driven to move, and the middle die 15 and the lower die 14 are separated. Through a linkage plate, only one driving device is needed to realize the separation or the pressing of the lower die 14, the middle die 15 and the upper die 16. In other embodiments, two driving devices may be further provided, which respectively drive the turning plate 12 to rotate and the top plate 11 to move vertically, so as to separate or press the lower die 14, the middle die 15 and the upper die 16.

Referring to fig. 3, the top plate 11 is provided with a moving plate 112, a mounting block 113, and bolts 114. The lifting column 111 is screwed to the moving plate 112. The moving plate 112 is disposed on the upper surface of the top plate 11, the mounting block 113 is disposed on the lower surface of the top plate 11, and the moving plate 112 and the mounting block 113 are fixed by bolts 114. In the present embodiment, after the bolt 114 bolts the moving plate 112 and the mounting block 113, the bolt 114 is located at the side of the top plate 11, and the moving plate 112 and the mounting block 113 clamp the top plate 11 by the bolt 114. When the position of the lifting column 111 on the top plate 11 needs to be changed, only the clamping position of the moving plate 112 and the mounting block 113 on the top plate 11 needs to be changed.

Referring to fig. 4, the lifting column 111 includes a connection cylinder 1111, a support rod 1112, and a spring 1113. The support rod 1112 is inserted into the connecting cylinder 1111 and slidably connected to the connecting cylinder 1111. The spring 1113 is disposed in the joint barrel 1111, and both ends of the spring 1113 abut against the bottom of the joint barrel 1111 and the end of the support rod 1112, respectively, so that the support rod 1112 has a buffering function with respect to the joint barrel 1111. In the process that the top plate 11 drives the lifting column 111 to abut against the jacking strip 131, the spring 1113 can also reduce the acting force of the lifting column 111 just contacting the jacking strip 131, so that the jacking strip 131 can drive the middle die 15 to slowly open the die, and the reject ratio of products in the die opening process is reduced.

Referring to fig. 1 and 5, a receiving through groove 1311 is provided on the jacking strip 131. The middle mold 15 is placed in the receiving through groove 1311, and is limited by the side wall of the receiving through groove 1311, reducing the position shift of the middle mold 15. Positioning holes 1312 are formed at both ends of the jacking bar 131, and a positioning pin 132 is disposed on the bearing plate 13 at the projection of the jacking bar 131. The positioning pin 132 and the positioning hole 1312 are matched, so that the position of the jacking strip 131 when placed on the bearing plate 13 is not deviated, and meanwhile, the guiding function is also achieved, and the jacking strip 131 can slide vertically conveniently. In this embodiment, the number of the positioning pins 132 is provided with a plurality of positioning pins 132, and the plurality of positioning pins 132 are uniformly distributed on the bearing plate 13 along the direction in which the two jacking strips 131 are close to or far away from each other. When the distance between two jacking strips 131 needs to be adjusted, the distance between two jacking strips 131 can be changed by inserting the jacking strips 131 into different positioning pins 132.

Two limiting strips 133 are further arranged on the bearing plate 13, and the two limiting strips 133 are distributed at the end positions of the two jacking strips 131, namely the two jacking strips 131 and the two limiting strips 133 are respectively located on four edges of the rectangle. When the jacking strips 131 are not abutted by the lifting columns 111 and the jacking strips 131 and the bearing plate 13 are kept in an abutting state, the limiting space 2 is formed between the two limiting strips 133 and the two jacking strips 131. The lower die 14 is placed in the limiting space 2, and the position movement of the lower die 14 is limited by the limiting space 2.

The carrier plate 13 is further provided with a kidney-shaped hole 134, and the kidney-shaped hole 134 is matched with the lifting column 111, so that the lifting column 111 passes through the carrier plate 13 and then abuts against the jacking strip 131. By forming the kidney-shaped hole 134, the distance between the two jacking strips 131 can be limited within the range of the bearing plate 13, so as to avoid the excessive distance between the jacking strips 131 as much as possible. In this embodiment, the length direction of the kidney-shaped hole 134 is the same as the direction in which the two jacking strips 131 are close to or far from each other, so that after the position of the jacking strips 131 is adjusted, the lifting column 111 can always abut against the jacking strips 131 to be lifted.

The implementation principle of the embodiment of the application is as follows: the turnover plate 12 is turned over on the rack 1, so that the upper die 16 is gradually far away from the middle die 15, the separation between the die and the product is further realized, the turnover plate 12 is turned over on the rack 1, the space between the upper die 16 and the middle die 15 after the die opening is increased, and the product is convenient to take out; the vertically sliding top plate 11 can drive the lifting column 111 to move towards the jacking strips 131 until the lifting column is abutted, and under the action of the lifting column 111, the two jacking strips 131 drive the middle die 15 to vertically move, so that the middle die 15 and the lower die 14 are separated; and the middle mold 15 is placed in the receiving through groove 1311, which also facilitates the removal and placement of the middle mold 15.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
