Abstract
The utility model relates to an epoxy resin vacuum casting curing pressurization device, comprising a main body and a pressurization device, wherein the main body comprises a mould which is installed in a big sealed can and is already cured and shaped, and a water can at the lateral side of the big sealed can; the pressurization device is disposed on the big sealed can and is communicated with the big sealed can. The utility model is provided with the beneficial effects that a certain pressure is applied on the blended liquid material during the curing process of epoxy resin vacuum casting to ensure full filling of liquid, reducing contraction marks and shrinkage pools. By using the utility model, the product is more compact, the mechanical strength is added and the integral quality of the insulator is enhanced.
Description
Technical field
The utility model relates to a kind of epoxide resin vacuum cast cured explosive device, relates in particular to mould material feeding in this device.
Background technology
As shown in Figure 1: the existing technology of epoxide resin vacuum cast is such: with the airtight big jar of putting into after mould 1 heating after the vacuumizing of heat 2, top 3 heating that mixture of epoxy resins are placed on big jar mix (will vacuumize equally), to constantly certain, pipeline 4 by sealing, utilize the deadweight of compound to flow in the mould in airtight big jar, to be placed in the other baking oven heat tracing after the mould material feeding is finished and be convenient to reaction and solidify, and solidify feeding and finish by the deadweight of material itself fully; For better feeding, also near cast gate, increase water tank 5, prevent that the too high curing of resin mixture temperature herein from influencing feeding.
The insulating part of epoxide resin vacuum moulding by casting generally uses in super-pressure electrical equipment, and very important effect is arranged, and not only performance requirement height, and cost occupies bigger proportion.But solidify the shrink mark that unavoidable product appearance causes inadequately owing to feeding in the feeding process, the defective of the nest that contracts outward appearances such as (as A places among Fig. 1) by deadweight.If can use with the flat back of very thin sand papering degradation when shrink mark is not obvious, and the shrink mark area is big, the nest that contracts can cause product rejection, causes damage.How overcoming these defectives is problems that the technical staff will solve.
Summary of the invention
The utility model technical issues that need to address provide a kind of epoxide resin vacuum cast cured explosive pressue device, are intended to solve the above problems.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:
The utility model comprises: body; Described body comprise be placed in airtight big jar in the mould of curing molding; At the other water tank of airtight big jar side; Also comprise: the pressing mechanism that communicates on airtight big jar, with airtight big jar.
Compared with prior art, the beneficial effects of the utility model are: the fluid mix in the epoxide resin vacuum cast cured explosive process is imposed certain pressure, guarantee liquid to fill type full, reduce the appearance of shrink mark, the nest that contracts.And making product fine and close more, mechanical strength increases, and improves the total quality of insulating part.
Description of drawings
Fig. 1 is an epoxide resin vacuum cast cured explosive schematic diagram in the prior art;
Fig. 2 is the utility model structural representation.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described in further detail:
As seen from Figure 2: the utility model comprises: body 10; Described body 10 comprises and is placed in airtight big jars 2 the mould 1 of curing molding; At the other water tank 5 of airtight big jar 2 side; Also comprise: on airtight big jars 2, with airtight big jar 2 pressing mechanisms that communicate 20;
Described pressing mechanism 20 comprises: connect the compressed-air actuated gas joint 21 that charges and discharge; Charging and discharging charging and discharging valve 22 of gas joint 21 arrangements; Charging and discharging gas joint 21 links to each other with the airtight big jar of 2 compressed air air chambers 24 that communicate by tube connector 23.
Operation principle of the present utility model is as follows: after die casting is finished, pour water in water tank earlier, then pressing mechanism is anchored on one with screw with mould, it is sealed with sealing ring with mould contact surface, prevent gas leakage.With valve open, the step-down air that contracts is received and is charged and discharged on the gas joint, charges into compressed air in airtight air chamber, substitute the bad for the good behind the gas valve closing,, make it keep pressure cast gate place liquid resin compound with the compressed air sealing, be convenient to feeding, wait to solidify and open the valve venting when finishing the demoulding again.
Claims (2)
1. an epoxide resin vacuum cast cured explosive pressue device comprises: body; Described body comprise be placed in airtight big jar in the mould of curing molding; At the other water tank of airtight big jar side; It is characterized in that also comprising: the pressing mechanism that communicates on airtight big jar, with airtight big jar.
2. epoxide resin vacuum cast cured explosive pressue device according to claim 1 is characterized in that described pressing mechanism comprises: connect the compressed-air actuated gas joint that charges and discharge; Charging and discharging charging and discharging valve of gas joint arrangement; Charging and discharging the gas joint links to each other with the compressed air air chamber that airtight big jar communicates by tube connector.
