Description of drawings:

Fig. 1: be the utility model trailing type molding device structural representation.

The specific embodiment:

The utility model will be further described below in conjunction with drawings and Examples.

In Fig. 1, the push-down head 3 that the utility model trailing type molding device comprises seaming chuck 1 and adapts with it, described push-down head 3 is fixing pressure head, described seaming chuck 1 and push-down head 3 are cylindricality, framed 2 are sleeved on the outside of the described seaming chuck 1 and the push-down head 3 of coaxial relatively setting, described framed 2 inwall is the cylinder that adapts with seaming chuck 1, and be with seaming chuck 1 and push-down head 3 and be slidingly matched, described seaming chuck 1, framed 2, push-down head 3 is on the same axis, push-down head 3 constitutes the die cavity 5 of inserting blank towards framed 2 one side and framed 2 inwalls and seaming chuck 1 towards framed 2 one side, be connected with stripper apparatus on described framed 2, described stripper apparatus aids in described framed 2, described framed 2 position is symmetrical in seaming chuck 1 and push-down head 3 relative framed 2 displacements at any time, be framed 2 with seaming chuck 1 press down and servo-actuated in seaming chuck 1, be between the push-down head 3 and with seaming chuck 1 and push-down head 3 and be slidingly matched, described stripper apparatus is that 2 demoulding oil jars 4 are arranged symmetrically in framed 2 both sides, plays demoulding effect.

Action when trailing type molding device of the present utility model is used is as follows: this device is loaded in the forcing press, provides required drive by forcing press, die cavity 5 sections are brick shape, are the pressure brickmaking machine; At first framed 2 are lifted by framed oil cylinder 4 and to be sleeved on the push-down head 3, behind feed, the pressure of hydraulic mandril acts on seaming chuck 1 and pressure is passed to blank, blank is under pressured state, pressure transmits mutually by the adjacent blanks particle, particle generation relative motion, neighbor distance changes, thereby realize that blank is by loose transformation to densification, when reaching certain pressure, blank produces to inwall tension all around because of pressurized, this tension becomes the frictional force that hinders framed 2 motions around acting on framed inwall, when framed 2 suffered frictional force are enough to overcome framed gravity, at this moment remove lifting of 4 pairs framed 2 of framed oil cylinders, framed 2 are not subjected to the effect of external force, only be subjected to the effect of internal friction power, be in quick condition, float between seaming chuck 1 and the push-down head 3, when seaming chuck 1 and push-down head 3 continuation extrusion billets, at this moment framed 2 be follow that seaming chuck 1 moves and servo-actuated between seaming chuck 1 and push-down head 3, make the top and bottom equalization of pressure of brick, after pressure reached rated value, brick i.e. compression moulding, at this moment, 4 pairs framed 2 of framed oil cylinders apply with along the power of vertical axis towards push-down head 3 directions, be downward power, move down framed 2 that described demoulding oil jar 4 is connected with press frame, at this moment adobe deviates from framed 2 and brick output, has promptly finished all processes of brickmaking.
