Description
Technical field
The utility model relates to rubber roll production, especially a kind of rubber roll casting mold.
Background technology
The production of polyurethane rubber roller by corresponding die casting, is treated polyurethane hot setting aftershaping usually.At present, the rubber roll casting mold of each polyurethane rubber roller manufacturing enterprise employing is generally vertical.Vertical rubber roll casting mold comprises an internal diameter vertical cylindrical shell consistent with the rubber roll external diameter, is positioned at the bottom plate of cylindrical shell bottom, passes bottom plate and fixing rubber roll roll shaft, for conveniently stripped, cylindrical shell is that split type structure is made up of two tile semicircular arc steel plates, surrounds the die cavity that constitutes the cast polyurethane moulding by cylindrical shell and bottom plate.For the axiality that guarantees that the rubber roll roll shaft is installed, also be provided with upper head plate in the cylindrical shell upper end usually, upper head plate is provided with plug hole and steam vent.
Vertical rubber roll casting mold, because cylindrical shell bottom, that bottom plate bears pressure is bigger, therefore to making the requirement of strength height of cylindrical shell, bottom plate material, so Mold Making cost height.Simultaneously, for the bonding strength that guarantees cylindrical shell and bottom plate, the sealing of mold bottom, bottom plate is all fixing by welding with, roll shaft, cylindrical shell bottom, need remove the vestige of spot welding when therefore utilizing this mould once more, the increase operation.When adopting vertical die, especially when producing the rubber roll that diameter is less, length is long,, in the time of cast, easily fall down owing to the center of gravity height, very dangerous; The exhaust line path length is easy to generate bubble and lacks the material phenomenon in the casting process, influence product quality, especially at mold bottom; Bad to rubber roll density control up and down, be easy to generate and lay particular stress on.
The utility model content
It is low that technical problem to be solved in the utility model provides a kind of cost of manufacture, and casting process safety, convenience can guarantee the rubber roll casting mold of rubber roll quality.
The technical scheme that its technical problem that solves the utility model adopts is: the rubber roll casting mold, comprise roll shaft, cylindrical shell, end plate, described roll shaft is coaxially installed on cylindrical shell by end plate, described cylindrical shell is made of horizontally disposed C jacket tube, described C jacket tube axially is provided with poured joint at its top along roll shaft, described end plate comprises first member plate and right end plate, described first member plate is fixedlyed connected with C jacket tube by the structure that removably connects respectively with right end plate, is surrounded the die cavity that constitutes moulding by casting by first member plate, right end plate and C jacket tube.
The beneficial effects of the utility model are: mold height is low, and the requirement of strength of therefore making material is low, and it is fixing that end plate and cylindrical shell need not welding, easy to make, material, cost of manufacture are low, and the recycling of mould is convenient, overall weight reduces, and center of gravity reduces, so casting process safety.Casting process can be by poured joint back and forth cast or pour into a mould simultaneously by a plurality of cast mechanism back and forth, and therefore cast makes things convenient for, and exhaust is more unobstructed, avoid bubble and lacked the generation of expecting phenomenon, rubber roll density control is better, and the generation of having avoided laying particular stress on phenomenon has guaranteed the quality of rubber roll.
Further, the C jacket tube of described poured joint both sides connects by position limiting structure.
Further, described C jacket tube adopts galvanized iron sheet to make, and described first member plate and right end plate all adopt timber to make.
Further, described first member plate and right end plate are inserted in the C jacket tube respectively and the difference tight fit, and fastening under the position limiting structure effect.
Further, described position limiting structure comprises the limited block that is arranged at poured joint both sides on the C jacket tube respectively, and described two limited blocks connect by one group of caging bolt that is provided with along poured joint; Described caging bolt comprises three that are arranged at two ends and centre position at least.
Further, described first member plate, right end plate are fixedlyed connected with roll shaft with lock-screw radially by axle sleeve respectively.
Description of drawings
Fig. 1 is the right view of utility model;
Fig. 2 is that the A-A of Fig. 1 is to cutaway view.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
As shown in Figure 1 and Figure 2, rubber roll casting mold of the present utility model, comprise roll shaft 1, cylindrical shell, end plate, described roll shaft 1 is coaxially installed on cylindrical shell by end plate, described cylindrical shell is made of horizontally disposed C jacket tube 2, described C jacket tube 2 axially is provided with poured joint 5 at its top along roll shaft 1, described end plate comprises first member plate 3 and right end plate 4, described first member plate 3 is fixedlyed connected with C jacket tube 2 by the structure that removably connects respectively with right end plate 4, surrounds the die cavity that constitutes moulding by casting by first member plate 3, right end plate 4 and C jacket tube 2.
Mold height is low, and the requirement of strength of therefore making material is low, and it is fixing that end plate and cylindrical shell need not welding, easy to make, and material, cost of manufacture are low, and the recycling of mould is convenient, and overall weight reduces, center of gravity reduction, so casting process safety.Casting process can be by poured joint 5 back and forth cast or pour into a mould simultaneously by a plurality of cast mechanism back and forth, and therefore cast makes things convenient for, and exhaust is more unobstructed, avoid bubble and lacked the generation of expecting phenomenon, rubber roll density control is better, and the generation of having avoided laying particular stress on phenomenon has guaranteed the quality of rubber roll.
In order to guarantee the shape of C jacket tube 2 integral body, the circularity at its middle part especially, the C jacket tube 2 of described poured joint 5 both sides connects by position limiting structure, reduces the distortion of C jacket tube 2.
Mould can adopt various materials to make, and is concrete in order to reduce cost, and described C jacket tube 2 adopts galvanized iron sheet to make, and described first member plate 3 and right end plate 4 all adopt timber to make.
Further, operation for convenience, described first member plate 3 and right end plate 4 are inserted in the C jacket tube 2 respectively and the difference tight fit, and fastening under the position limiting structure effect.Elasticity of wood, toughness are better, therefore fastening effective, good airproof performance.
Above-mentioned position limiting structure can be arbitrarily, as spacing steel bushing of circle etc., but best, described position limiting structure comprises the limited block 6 that is arranged at poured joint 5 both sides on the C jacket tube 2 respectively, and described two limited blocks 6 connect by one group of caging bolt 7 that is provided with along poured joint; Described caging bolt 7 comprises three that are arranged at two ends and centre position at least.The limited block 6 of both sides also the time plays the effect of drainage in cast in spacing, limited block 6 can also prevent the distortion on C jacket tube 2 axially simultaneously.Concrete, in example as shown in the figure, caging bolt 7 is provided with five.
Can fix by frictional force by the spacing fixing or tight fit of step between first member plate 3, right end plate 4 and the roll shaft 1, but in order to guarantee versatility and fastening strength, ready-made, described first member plate 3, right end plate 4 are fixedlyed connected with roll shaft 1 with lock-screw 8 radially by axle sleeve 9 respectively.
