Detailed Description

The following detailed description will be given with reference to specific embodiments, so as to solve the technical problems by applying technical means and to fully understand and implement the technical effects of the present invention.

Example one

Referring to fig. 1 to 4, a melamine tableware forming device, includes frame 100, install the last mould 1 and the lower mould 2 of mutually supporting extrusion on the frame 100, it is connected with the hydraulic lifting unit who drives its reciprocal lift from top to bottom to go up mould 1, specifically, hydraulic lifting unit include fixed mounting go up the pneumatic cylinder 3 of mould 1 top frame 100, with two guide bars 31 that 3 piston rods syntropy of pneumatic cylinder set up, the tip rigid coupling of 3 piston rods of pneumatic cylinder has a roof 32 to be used for the installation go up mould 1.

The upper end opening week side of lower mould 2 has outside extension platform 21 that extends, go up mould 1 include with the mould core of 2 adaptations of lower mould and install the grinding component of mould core upper end, the grinding component is including grinding wheel 4, grinding wheel 4 is rotatable to be installed the mould core upper end, be connected with its pivoted of drive motor 41 on the grinding wheel 4, work as when going up mould 1 and lower mould 2 cooperation, grinding wheel 4 contradicts extend on the platform 21, constitute the die cavity 200 that the shaping was used between grinding wheel 4, last mould 1, the lower mould 2. According to the technical scheme, the upper die 1, the lower die 2 and the polishing wheel 4 form a molding die cavity 200, after hot press molding, the polishing wheel 4 rotates through the rotating motor 41, and then waste materials generated by molding and a joint line are directly polished, polishing processes are integrated in the molding process, so that the processes are reduced, and the efficiency is improved; the structure of the grinding wheel 4 is a detachable grinding block 42 structure, so that the shape of the grinding block 42 can be adjusted according to requirements to meet the shape requirement of a formed product, and meanwhile, the grinding wheel 4 can be maintained more simply and conveniently, so that the maintenance time is shortened, and the maintenance difficulty is reduced.

Structurally, the grinding wheel 4 has a disc-shaped base 4a and a downwardly extending side 4b, and a grinding block 42 of annular configuration is mounted on the side 4 b. Abrasive brick 42 at this moment is complete loop configuration, bolt through lateral part 4b surface during the installation is direct rather than fixed, this loop configuration's abrasive brick 42 directly is located the upper end open position of melamine tableware, it can directly polish to rotate motor 41 and start after its shaping, this process of polishing is gone up mould 1 and lower mould 2 separation before, and then most raise dust parcel that will form when polishing is in wheel 4 of polishing, reduce the pollution to operational environment, and on this basis, can set up the raise dust of polishing that negative pressure adsorption structure produced in order to adsorb in wheel 4 of polishing or the similar position of last mould 1, further ensure operational environment's cleanness.

When the device is installed, the mold core is fixedly connected to the lower end of the top plate 32, the base part 4a is rotatably covered on the upper end of the top plate 32, and the side part 4b extends downwards from the periphery of the base part 4a and covers the mold core; specifically, a bearing 33 and a mounting seat 34 matched with the bearing 33 are installed on the end portion, close to the piston rod, of the hydraulic cylinder 3, a hole is formed in the center of the base portion 4a, the hole is fixedly connected to the mounting seat 34 through the hole to meet the rotation requirement, and the rotating motor 41 is in belt transmission connection with the mounting seat 34 to drive the grinding wheel 4 to rotate.

In this embodiment, one side of the grinding block 42 close to the mold core is an arc-shaped surface; the lower extreme of this arcwall face is along having the crooked towards mold core one side to make tableware turn-ups bottom after the shaping form corresponding arc, but this crooked too can not be to central skew, must guarantee can the drawing of patterns can.

Example two

Referring to fig. 5, compared with the first embodiment, the grinding wheel 4 has a disc-shaped base 4a and a side portion 4b extending downward, the side portion 4b is provided with two symmetrically distributed mounting grooves 43, and a grinding block 42 protruding from the inner surface of the side portion 4b is mounted on each mounting groove 43. In this configuration, the height of the blocks 42 protruding from the inner surface of the side portion 4b is 1 mm; therefore, after forming, when the precision of the material amount for forming is insufficient, the positions where the grinding blocks 42 are not installed can form overflow grooves for collecting the material, and the grinding blocks 42 rotate after forming to grind the part of the material.

The technical solution is not specifically stated for the heat supply structure during molding, and it may be an electric heating tube embedded around the lower mold 2, but the structure is not a main improvement point of the present application and is well known to those skilled in the art, and will not be described herein.

While the invention has been particularly shown and described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
