Utility model content

The purpose of this utility model is to provide a kind of desktop mold of new material desk.

The technical solution of the utility model is specially：

A kind of LFT-D is molded office table desktop mold, including grinding tool under grinding tool, desktop on desktop, is set on grinding tool under desktop There are desktop chamber corresponding with desktop, the bottom of desktop chamber to be equipped with connection boss chamber corresponding with connection bump, be additionally provided with Transverse stiffener rib corresponding with transverse stiffener rib channel is equipped with the corresponding vertical stiffener rib channel of vertical stiffener rib.

Transverse stiffener rib channel, vertical stiffener rib channel all unicom are extraneous.

Compared with the existing technology, the technique effect of the utility model is that the LFT-D techniques that the utility model uses have warp The advantage of Ji and environmental protection produces waste（Leftover pieces etc.）With the component in end lives period（Desk）It can be used, More more options are provided to furniture market.

Specific implementation mode

Such as Fig. 1, Fig. 5, a kind of LFT-D moldings desk, including desktop 10, the lower part of the four corners of desktop 10 are all fixed One hollow table leg 20, table leg 20 divide table leg left part 28 and table leg right part 29 to be fixed together, desktop 10, table leg left part 28, table leg right part 29 all uses LFT-D global formations.

Such as Fig. 2, in order to save material, the ratio that desktop can be done is relatively thin, for this purpose, the back side of desktop 10 is equipped with multiple willfully strong Muscle 12.

Such as Fig. 3, in order to save material, desktop can be done thinner, for this purpose, the back side of desktop 10 is equipped with multiple transverse stiffener ribs 12, vertical stiffener rib 13.

Such as Fig. 4, desktop 10 and the fixation of table leg 20 are specially：The lower part of the four corners of desktop 10 is fixedly connected with boss 11, the upper fixing flange 21 of table leg 20, connection boss 11 is fixed with flange 21 by screw, connection boss 11, desktop 10LFT-D global formations.

Such as Fig. 5, flange 21 is also classified into flange left part and flange right part, and flange left part is whole using LFT-D with table leg left part Molding, flange right part use LFT-D global formations with table leg right part.

Such as Fig. 6-7, table leg left part 28 and the fixation of table leg right part 29 are specially：The company of table leg left part 28, table leg right part 29 Junction is serrated face（Referring to reference numeral 281）, the protrusion of one of part inlays into the depressed area of another part, together Sample, flange left part are also so to connect with flange right part（Referring to reference numeral 212）.

Such as Fig. 5, prevent it from splitting for crack, table leg 20 is enclosed at least two leg cuffs 27.

Such as Fig. 8-9, a kind of table leg mold, including grinding tool 61 under grinding tool 69, table leg on table leg, under table leg grinding tool 61 be equipped with 28 corresponding main chamber 62 of table leg left part, one end connection flange chamber 63 of main chamber 62, the lower surface of grinding tool 69 exists on table leg The corresponding position of main chamber 62 is equipped with semi-cylindrical raised line 58.One table leg mold can produce a table leg left part 28 or table leg Right part 29.

Such as Fig. 8, in order to extrude serrated face, the lower surface of grinding tool 69 is equipped with zigzag in the corresponding position of serrated face on table leg Protrusion 68, the space connection between two adjacent saw-tooth shape protrusions 68 is extraneous, and in press mold, extra hot blank is not easy to flow out, Behind the extraneous channel of connection, hot blank is contributed to flow out.

Such as Figure 10, a kind of desktop mold, including grinding tool 71 under grinding tool 79, desktop on desktop, grinding tool 71 is equipped under desktop The bottom of desktop chamber 72 corresponding with desktop, desktop chamber 72 is equipped with connection boss chamber 73 corresponding with connection bump 11, It is additionally provided with transverse stiffener rib corresponding with transverse stiffener rib 12 channel 74, is equipped with 13 corresponding vertical stiffener rib channel of vertical stiffener rib（In figure Do not draw）.Transverse stiffener rib channel 74, vertical stiffener rib channel all unicom are extraneous, and hot blank is contributed to flow out.

Its working principle is that：

When this desk produces, a desktop is extruded using desktop mold, four pairs of table legs are extruded respectively using table leg mold Left part 28, table leg right part 29 are cooled and shaped.The hot blank of outflow may be reused, without waste material.

Table leg left part 28, table leg right part 29 are combined again, complete to fix using leg cuff 27.

Finally, connection boss 11 is fixed with flange 21 by screw, completes the fixation of desktop and table leg, making finishes.

This desk does not have any pollution to human body, and weight is stronger, and intensity is larger, and after the damage of last desk, material may be used also To melt down, remake.

Other content participates in the prior art.

Above-described is only preferred embodiments of the present invention, it is noted that for those skilled in the art For, under the premise of not departing from the utility model general idea, several changes and improvements can also be made, these should also be considered as The scope of protection of the utility model.
