implementation manner

The upper frame 8 consists of the pressure plate 84, the positive tool 81 and lifting push rod 83. In each side of the pressure plate 84 there is a ramp pressure column 82 downwards, the lower frame 7 at the top has a negative shape 9 in contrast to the positive shape 81; Below the ramp pressure columns 82 in the lower frame 7 there are through holes 71 for the connection to the ramp pressure column 82. Between the through holes 71 in the lower frame 7 there is a symmetrical sliding trough 72 on both sides, between the sliding troughs 72 there is a membrane 77 which is connected to the lower frame 7. In each sliding trough 72 at the top there is a through hole 75 which goes through the lower frame 7 and is connected to the negative tool 9 at the bottom; in the through hole 75 there is a ramp unloading block 78, in each sliding trough 72 there are sliders 74, between each slider 74 and each diaphragm 77 there are springs 76; above each slider 74 there is ramp rail 742; underneath each slider 74 there is a guide block 743 which is inserted in the guide 73 and supports the connection. On the side of the slide 74, which is remote from the spring (76), there is a ramp head 741 which crosses the lower frame 7 and goes into the through hole 71.

There is a part 91 to be pressed on top of the negative mold 9.

Between the negative tool 9 and the lower frame 7 is a removable

Fixation provided. This makes the exchange of products of different types easy to implement.

The removable fixation between the positive tool 81 and the pressure plate can be easily replaced due to the exchange of products of different types. The connection between the pressure plate 84 at the top and the lifting push rod 83 at the bottom increases the stability during pressing.

In the beginning, the upper frame 8 stands far from the lower frame 7, the slide 74 by the force of the spring 76 presses the ramp head 741 into the passage hole 71, at the same time the ramp unloading block 78 touches the surface of the slide 74 in the passage hole 75 at the same time, the ramp unloading block 78 pulls at the same time above into the negative form 9.

During pressing, we move the upper frame 8 in the direction of the lower frame 7, so that the ramp pressure column 82 gradually pulls into the passage hole 71 until the ramp of the column 82 touches the head 741 with the ramp. The column 82 slides further downward, so that the head 741 brings the slide 74 against the force of the spring 76 in the direction of the sliding recess 72. When the head 741 is in the sliding recess 72, the outer side of the head 741 moves in the direction of the Spring, at the same time the block 78 interacts with the slide 73. When block 78 is opposite 742, block 78 falls into 742 by its own weight and the surface of block 78 is parallel to the surface of lower frame 7. At the same time, the lower side of 81 connects to the upper side of part 91 and the upper frame 8 is moved further down, so that the upper frame fits with the lower frame 9 to press part 91 a. Then the rod 83 moves up and brings 81 far from the 9, at the same time 82 separates from the 71. When it moves up, the outer side of the 741 moves down. When it reaches the lower side of the 82, the force from the spring 76 contacts 741 with 82, then 8 moves up and 74 pulls into 71, simultaneously touches 78 with 742, so 78 gradually pulls into 9 and touches with part 91 If 82 completely separates from 71, 741 is already completely in 71, at the same time 78 touches with 74 and then 91 of 9 is pushed out.

The advantages of the invention:

1. The auxiliary fixation that can be removed between the pressure plate and the positive tool and the auxiliary fixation that can be removed between the pressure plate and the negative tool means that the exchange due to the products of different types can be easily implemented, thus increasing the performance.

2. The ramp connection column and the through hole help the sliding connection and then guide the press movement in order to prevent deviation and bring more stability, while at the same time the slide and the sliding recess are controlled to support the connection, so that the adjustment between Ramp sliding trough and ramp unloading block controlled to move the ramp unloading block vertically, therefore the parts are fully pressed and after pressing the materials are automatically unloaded.

3. With the support of the spring and slide, the upper frame is automatically acknowledged after separation from the lower frame, so that is a repetitive one

Editing easier.

4. The invention has a simple structure and is stable and accurate when pressed, after pressing the materials can be automatically unloaded and the manufacturing costs are cheap, maintenance is also easy, particularly suitable for small and medium-sized companies.

Above is only the detailed implementation of the invention, but the

Claims for protection are not thus limited, every change or change that is not thought out by creative work is valid for the claim for protection of the invention. Therefore, the scope of the invention depends on the scope of protection.
