Abstract
The utility model discloses a rotational moulding is crowded device of annotating of screw thread push rod for mould relates to rotational moulding production facility field, establishes in mould one side, constitute by push rod and injection tube, the injection tube communicates with each other with the mould, the push rod includes and drift and screw rod is equipped with the measurement scale on the outer wall, the inside ka tai and the internal thread of forming a complete set with the screw rod that be equipped with of injection tube. The utility model discloses can confirm the push rod scale according to the fashioned diameter of product size, extrude the plastics of molten condition that make solid construction, both reduce cost improved product quality again, economical and practical.
Description
Technical field:
The utility model relates to rotational moulding production equipment field, is specifically related to a kind of Plastic Rolling Molds screw putter extruding injection device.
Background technology:
Rotational moulding product is double layer hollow structure, because not having internal mold and internal pressure during formed product, when customer requirement shaping solid structure, moulding process having very large difficulty, there will be boring state.Common way is by process modification by hot mode, or the method such as to optimize product structure is improved, and its effect can not tackle the problem at its root.
Utility model content:
Technical problem to be solved in the utility model is to provide a kind of easy to operate, economical and practical Plastic Rolling Molds screw putter extruding injection device.
Technical problem to be solved in the utility model adopts following technical scheme to realize:
A kind of Plastic Rolling Molds screw putter extruding injection device, is located at mould side, is made up of push rod and injection tube, described injection tube communicates with mould, described push rod comprises drift and screw rod, and screw rod outer wall is provided with metering scale, and described injection tube inside is provided with the chuck supporting with screw rod and internal thread.
The longitudinal center line of described push rod and rotational moulding product longitudinal center line are on same straight line.
Utility model works principle:
Before plastic product plasticizing, screw putter is returned to " 0 " scale, according to the diameter of formed product, calculating need push the consumption of molten plastic, determine that push rod pushes scale, after product melting, screw putter is rotated to assigned scale, treat that Inner plastic is squeezed into solid construction and retreats pushback pin.
The beneficial effects of the utility model are: structure is simple, reasonable in design, easy to operate, according to the diameter determination push rod scale of formed product, extrude the plastics of molten condition, make solid construction, both reduced costs, improved the quality of products again, economical and practical.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is using state figure of the present utility model;
Wherein: 1-mould; 2-push rod; 3-injection tube; 4-drift; 5-screw rod; 6-metering scale; 7-chuck; 8-internal thread.
Detailed description of the invention:
The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the utility model further.
As shown in Figure 1, 2, a kind of Plastic Rolling Molds screw putter extruding injection device, be located at mould 1 side, be made up of push rod 2 and injection tube 3, injection tube communicates with mould, push rod comprises drift 4 and screw rod 5, and screw rod outer wall is provided with metering scale 6, and injection tube inside is provided with the chuck 7 supporting with screw rod and internal thread 8.
The longitudinal center line of push rod and rotational moulding product longitudinal center line are on same straight line.
More than show and describe general principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and description just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
