Description
(1) technical field:
The utility model relates to the drum-type vacuum plastic suction forming apparatus of plastic products.
(2) background technology:
Existing plastics products vacuum forming machine is improved to step production from original two-step method production and gets final product, and is that raw material is the one-step method of goods through heating, vacuum suction moulding by sheet material.But the design of the frame for movement of one-step shaping has many treating with perfect place, all adopt track structure as existing integrally forming machine, mould and chain form the crawler belt of a cycle rotation, use 24 to 32 on mould, mould adopts air cooling to reduce mold temperature, in addition, vacuum suction adopts rail plate formula structure, with cylinder finish each time separation with combine.The whole series manufacture and design scheme and have following problem: 1, mould is many, cost is high; 2, cooling needs the blower fan blowing, and power consumption, production environment are poor; 3, vacuum forming day is operated in more than 50,000 times, finish by cylinder, and poor reliability, the fault rate height, the life-span is short.
(3) utility model content:
Technical problem to be solved in the utility model is at the problem that exists in the background technology, and a kind of simple in structure and dependable performance, long drum-type vacuum plastic suction forming apparatus of life-span are provided.
The invention for solving the technical problem can reach by following technical solution: the formed sheet of being extruded by extruder passes through cylinder, week at cylinder upwards is formed into the pattern tool, on the axle of cylinder the sprocket wheel that is meshed with power chain is housed, this axle is gone up spaced center into and out of water channel; Wherein, on two circumferential (circumferential) of axle, be drilled with two again and radially be communicated with into and out of water channel with above-mentioned center respectively, radially also be communicated with formation water cooling circulation canal with mould with water inlet pipe, outlet pipe respectively into and out of the hole into and out of the hole at two places on the axle; Sealing gland is housed on axle, and it is made of quiet, rotating ring, has axial hole to pass through pipe on the stationary ring and is connected with vavuum pump; Have on the rotating ring with stationary ring on the hole involutory and with number of molds identical hole, each hole is with pipe and corresponding mould connection.
In such scheme, the cross section of each mould is trapezoidal.Form one section arc-shaped cavity that is communicated with the hole on the involutory surface of stationary ring, the hole is involutory on convenience and the rotating ring.Drum shaft is enterprising, liquid packing is equipped with at the two ends of water outlet.Radially be communicated with into and out of water channel with the center respectively upwards being drilled with identical with number of molds 2 two weeks of axle into and out of the hole, each radially into and out of the hole respectively with water inlet pipe, outlet pipe and corresponding mould connection formation water cooling circulation canal; Rotation by cylinder makes plastic sheet suck mould under the effect of vavuum pump, makes the goods of moulding break away from mould again under the effect of cooling water, works continuously, and finished product is produced successively.Because it is simple in structure, dependable performance can reach purpose of design.
The utility model is compared with the above-mentioned background technology can have following beneficial effect: change former track structure into the water cooling drum-type structure, rectilinear motion is changed over rotatablely move; Change wind cooling temperature lowering into water-cooled cooling, improved heat exchange efficiency, can effectively reduce the required number of molds of moulding; Change the vacuum environment of plastic uptake into rotation mode by original line style motion, save plastic uptake with cylinder part and sync control device.
