Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Fig. 1 and 2 show the structure of such a mold carriage, and several embodiments are listed below with reference to the figures.

Example 1:

the utility model provides a mould car, is including installing in the die block of frame 1 and setting up in end mould 3 and the side form 2 of die block side, 3 bottoms of end mould and frame 1 between the activity articulated, 2 outer walls of side form be close to end mould 3 and locate to rotate through pivot 4 and be provided with lock pole 5, lock pole 5 is being provided with draw-in groove 6 near 3 one end belows of end mould, be provided with protruding pole 7 that corresponds with draw-in groove 6 on the 3 outer walls of end mould the terminal surface of side form 2 is provided with protruding nail 13, the inner wall of end mould 3 is provided with vertical strip groove 14 in the department of corresponding with protruding nail 13.

The bottom die, the end die 3 and the side die 2 form a cavity to form a forming cavity of the plate, when the die is closed, the end die 3 is rotated through the rotating shaft 4 to be closed with the bottom die and the side die 2, and then the buckling rods 5 on the outer wall of the movable side die 2 are buckled with the clamping grooves 6 of the buckling rods 7 on the outer wall of the end die 3, so that the end die 3 is tightly closed with the bottom die and the side die 2. When the die is closed, the convex nails 13 of the side die 2 are inserted into the vertical slots 14 of the end die 3 to form an accurate positioning mechanism, so that the product quality is improved. When the mold is opened, the buckling rod 5 is lifted upwards, the end mold 3 is automatically loosened, and the mold closing and opening are convenient, so that the mold is suitable for large-scale production.

Example 2:

on the basis of the embodiment 1, it is further defined that the size of the card slot 6 gradually decreases from the opening to the deep part. When the clamping groove 6 is buckled with the convex rod 7, along with the gradual reduction of the size of the clamping groove 6, the buckling of the clamping groove 6 and the convex rod 7 is gradually tight until the optimal tightness degree can be reached.

Example 3:

on the basis of the embodiment 1, it is further defined that the buckling rod 5 is located between the end of the buckling rod 5 provided with the clamping groove 6 and the rotating shaft 4 from the end provided with the clamping groove 6 to the other end, and the center of gravity of the buckling rod 5 is located between the end of the buckling rod 5 provided with the clamping groove 6 and the rotating shaft 4. When the mold is opened, under the action of external force, the end, provided with the clamping groove 6, of the buckling rod 5 is in an upward lifting state, and after the mold is closed, due to the gravity center position of the buckling rod 5, the end, provided with the clamping groove 6, of the buckling rod 5 can automatically fall down to complete buckling when the external force is removed, so that the mold can be suitable for automatic production.

Example 4:

on the basis of the embodiment 3, it is further defined that a bearing block 8 for bearing the buckling rod 5 is arranged on the outer wall of the side die 2 in the area between the end die 3 and the rotating shaft 4; and a lower pressing groove 9 is arranged above the other end of the buckling rod 5 provided with the clamping groove 6. When the mould is opened, external force is applied to the downward pressing groove 9, one end of the buckling rod 5 provided with the clamping groove 6 is lifted to open the end mould 3, the buckling rod 5 is placed under the condition of removing the external force and is born by the bearing block 8, the downward rotation cannot be continued, the external force is not required to be kept all the time, therefore, the side mould 2 convenient to carry out other actions according to production needs, when the mould is closed, the pressing groove 9 is pressed down again to lift one end of the buckling rod 5 provided with the clamping groove 6, and the mould is suitable for automatic production.

The most preferred embodiment is as follows:

on the basis of the embodiment 1, it is further defined that the end mold 3 is hinged to the frame 1 through the ear plates 10 arranged on both sides of the frame 1 and a second rotating shaft 11 penetrating through the ear plates 10 and the frame 1, and a cross bar capable of contacting with the frame 1 to limit the rotation angle of the end mold 3 is arranged between the ear plates 10. When the die is opened, the end die 3 is turned downwards to a certain degree, and the cross rod is limited by the rack 1 so as to limit the turning degree of the end die 3, thereby facilitating the subsequent die closing of the end die 3. On the basis, a spring is further arranged between the cross rod and the rack 1 and plays a role in buffering, and noise and damage caused by direct impact between the cross rod and the rack 1 are prevented.
