Abstract
The utility model discloses a resistor disc vacuum forming mould. The resistor disc vacuum forming mould comprises an upper template, a negative template and a fixed plate, wherein the fixed plate is provided with a lower punch base plate, and the lower punch base plate is provided with a lower punch; the upper template is provided with an upper punch base plate, and an upper punch is arranged below the upper punch base plate; the negative template is provided with a mould sleeve, and the mould sleeve is respectively matched with the upper punch and the lower punch. The resistor disc vacuum forming mould provided by the utility model has the advantages that the negative template, the upper punch and the lower punch are linked so as to punch in a pressing process, and meanwhile, a vacuum plant matched with a lower end pressing plate of the upper punch can enable a resistor disc to exhaust and press, so that the probability of an air hole generated by the resistor disc after firing formation is reduced, and the product performance is stable and balanced.
Description
Technical field
The utility model belongs to mechanical field, and what be specifically related to is a kind of resistor disc vacuum forming mould.
Background technology
Resistor disc is a kind of widely used anti-electric breakdown component, and the metal oxide powder of certain proportioning is compressing after sufficiently mixing, more makes the comparatively resistor disc of stability characteristic (quality) through the series of processes such as firing.In the compressing stage, all generally that although after Multi-step forming, powder can be consolidated into bulk by the direct punch forming of raw material process, if but punching press is insufficient, can cause the resistor disc after moulding to have the part bubble, can affect the moulding of resistor disc in the follow-up process of firing, especially in use can affect the performance of resistor disc integral body, the bubble position is being arranged, resistor disc is easy to breakdown under low-voltage, makes the resistor disc overall performance not reach requirement, and performance is unbalanced.
The utility model content
The utility model purpose: the purpose of this utility model is in order to solve above the deficiencies in the prior art, and the resistor disc that a kind of pressing result is good, production efficiency is high vacuum forming mould is provided.
Technical scheme: resistor disc vacuum forming mould described in the utility model, its objective is such realization, a kind of resistor disc vacuum forming mould, comprise cope match-plate pattern, negative template and fixed head, described fixed head is provided with the low punch backing plate, on the low punch backing plate, installs low punch, described cope match-plate pattern has the upper punch backing plate, install upper punch under the upper punch backing plate, described negative template is provided with die sleeve, and described die sleeve is suitable with upper punch and low punch respectively.
Described fixed head is provided with jumper bar, and jumper bar is connected with the low punch backing plate.
The bottom of described upper punch is set with pressing plate, is provided with the elastic damping bar between pressing plate and cope match-plate pattern.
Resistor disc vacuum forming mould as above, described pressing plate connects vacuum extractor by pipeline, between the gap of pressing plate and upper punch, is negative pressure of vacuum.
Beneficial effect: resistor disc vacuum forming mould described in the utility model, by the negative template in pressing process and upper punch, low punch interlock punching press, coordinate vacuum extractor exhaust compacting, the resistor disc reduced after forming by a firing produces the pore probability, and properties of product are stable equilibrium more.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
In order to deepen understanding of the present utility model, below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail, and this embodiment only, for explaining the utility model, does not form the restriction to the utility model protection range.
Resistor disc vacuum forming mould shown in Figure 1, comprise fixed head 1, suit jumper bar 2 on fixed head 1, the upper end installing low punch backing plate 3 of jumper bar 2, low punch backing plate 3 can move up and down under the drive of jumper bar 2, some low punches 4 of installing on the low punch backing plate, the upper end of low punch 4 is overlapped in the die sleeve 6 of the negative template 5 of packing into, for guaranteeing to have good pressing result, be provided with mould tire 7 at the two ends of die sleeve 6, the upper end of negative template 5 is provided with cope match-plate pattern 8, the lower end of cope match-plate pattern 8 is provided with upper punch backing plate 9, the lower end installing of upper punch backing plate 9 is consistent with negative template 5 Upper Die-sleeve 6 quantity, the upper punch 10 that position is corresponding, the bottom suit pressing plate 11 of upper punch 10, be provided with elastic damping bar 12 between pressing plate 11 and cope match-plate pattern 8, under normal condition, pressing plate 11 is the lower ends that are positioned at upper punch 10, when upper punch 10 punching press die sleeve 6, pressing plate 11 moves reciprocatingly under the effect of elastic damping bar, prevent that the dusty raw materials in die sleeve 6 from splashing out, pressing plate 11 also connects vacuum extractor by pipeline 13 simultaneously, illustrated is a vacuum tank 14, more effectively prevent the generation of bubble in the resistor disc pressing process, further guaranteed the performance of resistor disc.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection range of the present utility model.
