Abstract
A fine casting sprue bush. The utility model discloses a double-deck runner cover, it includes runner cover body, and its head has the cylinder structure, including last cylinder and lower cylinder, go up cylinder upper surface center department and have one sunken, sunken center department is equipped with the feed inlet, feed inlet and pouring channel intercommunication, and this pouring channel cylinder-circular cone structure, feed inlet and pouring channel and the coaxial setting of body, the pouring channel has eight louvre structures outward, and body material is chromium alloy tool steel. The utility model discloses simple structure, reasonable in design, the cylinder-circular cone structure of inlayer has good pressure boost performance, and consequently the packing of the accurate injection molding of being convenient for is moulded plastics, and satisfies the requirement of moulding plastics of multiple plastics commonly used (polyethylene, polypropylene etc.), and eight louvres of outer increase can obviously strengthen the heat dispersion of runner cover.
Description
Technical Field
The utility model relates to a mould pouring field, concretely relates to injection mold's runner cover structure.
Background
Sprue bush is also called pouring nozzle, squirt nozzle, sprue bush, etc. and is a part for injecting molten plastic material from the nozzle of injection molding machine into the mold.
Traditional sprue bush structure, inside is conical structure, and pressure is less when extruding, and during the preparation meticulous foundry goods, pressure can't be enough injects the mould edge with the raw materials into completely, has consequently greatly influenced the efficiency of the production of moulding plastics, causes manufacturing cost to increase.
Disclosure of Invention
Problem (A)
An object of the utility model is to provide a meticulous pouring gate cover to the above-mentioned shortcoming that traditional conical pouring gate cover exists, increase the pressure in the pouring gate cover pouring channel for the material obtains bigger pressure before getting into the mould, the edge of the accurate article mould of packing that can be better, make this kind of pouring gate cover can be better fill the material full mould, have fine practical meaning and application prospect.
(II) technical scheme
In order to achieve the above object, the utility model adopts the following technical scheme: the utility model provides a meticulous pouring gate cover, its head has the cylinder structure including pouring gate cover body, and including last cylinder and lower cylinder, it is sunken to go up cylinder upper surface center department, and sunken center department is equipped with the feed inlet, feed inlet and pouring channel intercommunication, and this pouring channel divide into two parts, and the top is cylinder structure and diameter less, and the below part is the great cone structure of radius, and feed inlet and pouring channel and the coaxial setting of body have eight louvres outward.
(III) Effect
The utility model discloses the structure is comparatively simple, reasonable in design, and the inlayer is cylinder-circular cone structure, because the radius of cylinder-circular cone structure than traditional conical sprue bush is littleer, the pressure in the increase pouring channel that can be obvious, therefore the raw materials of the accurate injection molding of being convenient for are filled, satisfy the requirement of moulding plastics.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
In order to make the objects and advantages of the present invention more clear, the following description is given of an embodiment of the present invention with reference to the accompanying drawings.
A double-deck runner cover as shown in figure 1, it includes a runner cover body 1, and the upper end has the cylinder structure, including last cylinder 4 and lower cylinder 5, 4 upper surface centers department of last cylinder have one sunken 2, 2 centers department of sunken is equipped with feed inlet 3, feed inlet 3 and pouring channel 6 intercommunication, and this pouring channel 6 is cylinder-circular cone structure, and feed inlet 3 and pouring channel 6 and body 1 coaxial setting have louvre structure 7 outside the pouring channel, and louvre structure 7 has chromium alloy tool steel 8 of certain thickness outward.
To sum up, the utility model discloses simple structure, reasonable in design, the cylinder-circular cone structure of inlayer has good pressure boost performance, and consequently the packing of the accurate injection molding of being convenient for is moulded plastics, and satisfies the requirement of moulding plastics of multiple plastics commonly used (polyethylene, polypropylene etc.), and eight louvres that the skin increases can obviously strengthen the heat dispersion of runner cover.
The above only be the embodiment of the utility model discloses a, not consequently the restriction the patent range of the utility model, with the utility model discloses other sprue bush of the same or similar structure are all in the utility model discloses in the protection scope.
Claims (4)
1. The utility model provides a meticulous pouring gate cover which characterized in that: the sprue bush comprises a sprue bush body, wherein the top end of the sprue bush body is provided with a cylindrical structure, and an upper cylinder and a lower cylinder are connected to form an integral structure; the center of the upper surface is provided with a recess, the center of the recess is provided with a feed inlet and is communicated with a pouring channel, the pouring channel consists of two parts, the uppermost part is of a cylindrical structure, the lowermost part is of a large-mouth conical structure, and the pouring channel is externally provided with eight heat dissipation holes.
2. A fine casting sprue bushing according to claim 1 wherein the depression is a circular depression.
3. The fine casting sprue bush according to claim 1, wherein the diameter of the heat dissipation holes is 3-5 mm.
4. The fine casting sprue bush according to claim 1, wherein the diameter of the lower bottom of the conical-structure casting channel is 1-2 mm smaller than the diameter of the lower end of the sprue bush body.
