Abstract
The utility model relates to a plunger heating structure of a rubber injection molding machine, which comprises a charging barrel and a plunger adapting to the charging barrel in inner diameter. The plunger heating structure is characterized in that a plunger seat is arranged on the plunger; a heat insulation bearing plate is arranged on the plunger seat; a plunger joint is arranged on the heat insulation bearing plate; a deep hole is formed in the center of the plunger; a heating rod is arranged inside the deep hole; the plunger is fixed on the plunger seat through a plunger seat nut; and the plunger seat, the heat insulation bearing plate and the plunger joint are fixedly connected through bolts. The plunger heating structure has the advantages of simple structure, convenience in control, good self-cleaning performance of the plunger and easiness in clearance, and meets the manufacturing requirements of high-precision products.
Description
Technical field
The utility model relates to a kind of rubber injection machine technology, especially relates to a kind of plunger heating arrangement of rubber injecting press.
Background technology
The plunger of the vertical rubber injecting press of prior art, barrel generally are not provided with heating system, after agglomerating sizing material is put into barrel, down push by plunger, because plunger does not have heating, the thermograde of sizing material changes in this moment barrel directly influence quality of item, and plunger do not have heating, also thereby to cause plunger to clear up difficult, cause percent defective very high, do not satisfy the high accuracy product requirements.
Summary of the invention
Main purpose of the present utility model is: overcome the existing in prior technology deficiency, thereby develop a kind of rubber injecting press plunger heating arrangement that can improve quality of item, the rate of reducing the number of rejects and seconds.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of rubber injecting press plunger heating arrangement, has barrel, with the suitable plunger of barrel internal diameter, it is characterized in that: plunger mat is arranged above the plunger, heat insulation backing plate is arranged above the plunger mat, above the heat insulation backing plate plunger connector is arranged; There is a deep hole at described plunger center, in the described deep hole heating rod is arranged; Described plunger is fixed on the plunger mat by the plunger mat nut, and plunger mat, heat insulation backing plate and plunger connector are screwed connection.
The technical solution of the utility model can also be further perfect:
As preferably, gapped between described plunger mat nut and the plunger mat, to make things convenient for self-centering.
As preferably, have on the described plunger mat and be used for the metallic channel that the lead on the heating rod passes through.
The beneficial effects of the utility model are:
1) apparatus structure is simple, and control is convenient;
2) after the agglomerating sizing material of being extruded by make-up machine was put into barrel, internal and external temperature was even, easily insulation;
3) by injection characteristic decision injection more to the end, its injection pressure is high more, and the sizing material that needs this moment has certain thermograde to increase rubber mobility, will measure sizing material like this and be injected to die cavity fully, reduces the goods percent defective; Reach the manufacturing requirement of high accuracy goods.
4) the plunger self-cleaning is good, easy to clean; The effect of the sizing material big for viscosity especially, that flowability is poor is more obvious.
Description of drawings
Accompanying drawing 1 is a kind of structural representation of the present utility model.
Description of reference numerals: 1 is barrel, and 2 is plunger, and 3 is heating rod, and 4 is the plunger mat nut, and 5 is plunger mat, and 6 is heat insulation backing plate, and 7 is plunger connector.
The specific embodiment
Below by embodiment also in conjunction with the accompanying drawings, the technical solution of the utility model is further described in detail.
Embodiment:
Rubber injecting press plunger heating arrangement as shown in Figure 1, one deep hole is arranged in the middle of the plunger 2, heating rod 3 is installed in the deep hole of plunger 2, plunger 2 is fixed on the plunger mat 5 by plunger mat nut 4, and keeps certain clearance, but self-centering, convince wire casing on the plunger mat 5 by patient analysis and be used for placing the lead of heating rod 3, plunger mat 5 is screwed with plunger connector 7 and connects, the heat insulation good heat insulation backing plate 6 of middle placement, and plunger connector 7 connects with the notes compressing cylinder.
During use, at first plunger 2 is heated, after the agglomerating sizing material that machine to be formed is extruded is put into barrel 1, annotate compressing cylinder and drive plunger 2 to the pressure of making a bet, to the pressure of making a bet, its injection pressure is high more more, and the sizing material of this moment has certain thermograde to increase rubber mobility, to measure sizing material like this and be injected to die cavity fully, reduce the goods percent defective.
